Discuses two proven ways to make cigarettes safer: 1) A German patent obtained by American companies in 1966 that enables manufacture of cigarettes free from benzo-a-pyrene, and 2) Spraying tobacco with a non-toxic product called chemosol, which does not change taste or smoking characteristics.

January 6, ~966 Dr. W. M. Bright Re: A Process for the Elimination of Carcinogenic Properties of 3:4 - benzo - pyren in Cigarette Tobacco" An application for a German patent on the above process has been registered at the Geman Patent Office, Munich, Germany, under the number B 82 871 IV a/79c. The inventor is Dr. Max Bindlg. He has done research on cancer and is the Chief Hedlcal Doctor of the Medlcal Institute "Perclval- . Pott-Statlon" in Munich, Germany. In the practice of the invention, t~o pounds of an organic substance (unidentified) is added to about 333,000 grams of tobacco for manufacture into cigarettes (rate of application is about 0.3Z). As reported in Tabacologia 18 (No. 9) 25 (1962) aroma of the tobacco (presumably aroma of smoke upon smoking the tobacco) is not affected. It is claimed that the presence of the organic substance in the tobacco prevents the formation of 3,4-benzpyrene (same as 3:4 - benzo - pyren) during smoking. It is conceivable that the above conclusion may have been reached in good faith by the inventor with the analytical method he had available when his experiments were conducted. However, if the experiment and the analysis were repeated by us at this time, it is believed that only a moderate reduction, if any, of 3,4-benzpyrene would be observed. The following factorshave been considered in coming to this conclusion: I. Analytical Metho~ Considerable work has been done both here and in Europe on the development of a reli.able ~nalytical procedure for 3,4-benzpyrene in cigarette smoke. To our knowledge, all methods in use, as late as about six months ago have been extremely cumbersome and time consuming. Host of the methods rec the smoking of about 3,000 cigarettes and in no case less than 100 ci Accuracy of any of the methods was unsatisfactory. For exsmple, analysis may have showed a yield of 3,4-benzpyrene of 3 pg/100 cigarettes on one lot and 1.5 pg/100 cigarettes on a subsequent lot of cigarettes in the same experiment. It is conceivable that in making the analyses for Dr. Biudi~, the analyst might have obtained the value of 1.5 pg/lO0 cigarettes on the control and 0 pg/100 cigarettes on the test, whereas the actual values should have b~en 3 pg and 1.5 pg respectively. Nonetheless, Dr. Bindig could have logically concluded that the 3,4-benzpyrene had been eliminated. In no case have we been able to completely eliminate the 3,4-benzpyrene in our experiments with additives. We contend that many of the exaggerated claims which have been made by various investigators regarding reduction of 3,4-benzpyrene are attributable to unreliable analytical procedures. 2. Types of Additives None of the organic additives has reduced 3,4-benzpyrene in our experiments. Reduction has been achieved with inorganic additives, but never complete elimination. Three types of inorganlc additives are discussed below.
Page 8: 502076684
2 Classes of Inorganic Additives (a) Oxidizing Agents Cupric nitrate, potassium nitrate, magnesimnnitrate, aluminum perchlorate and others, have reduced 3,4-benzpyrene and other polycyclic hydrocarbons. However, the nitrates resulted in formation of toxic oxides of nitrogen. These additives are therefore deemed undesirable. (b) Sulfam£c Acid and Anmonlum Sulf~mate Moderate reduction of 3,4-benzpyrene has been achieved by the addition of these materials; however, flavor of smoke is adversely affected. (c) Aluminum Oxide Trihydrate The addition of 25Z by weight of the above reduces 3,4-benzpyrene by about 25Z. Reduction is attributable to lowering of burning temperature. It is believed that formation of 3,4-benzpyrene is one of the fundamental reactions in the smoking process. The prevention of formation of the material would therefore require a very substantial change in the smoking process. It is highly unlikely that this change can be brought about by an organic substance. I have discussed the patent with Dr. Teague,~He w~"~ot able to envisage an organic material that would reduce 3,4-benzpyrene in smoke. Extraction Procedures 3,4-Benzpyrene in smoke has been reduced by extraction of tobacco prior to smoking. The extraction (with hexane, ether, chloroform) removes long-chaln aliphatlc hydrocarbons (C15 through C33), sterols and solanesol, which are believed to be the main precursors of 3,4-benzpyrene. The mechanism of formation of 3,4-benzpyrene fro~ these precursors.ls believed to be a series of cyclizations, dealkylations and dehydrogenations. One would expect that oxidizing agents (i.e. KN03, and others) would affect these reactions. The effect of the anmoni~m sulfamate is obscure although i~could act as a burning retardant. A lowering of the burning temperature would be expected to affect these reactions and it is not surprising therefore to find that al~nina trihydrate reduces 3,4-benzpyrene. However, it is difficult to vis- ualize how an organic substance could affect these reactions. In v~ew of the above, I seriously question the validity of the Bindig patent and do not reconmend that we express any interest in it. Horeover, it should be recognized that the presence of a substantial smount of a foreign organic material in tobacco (0.3~) would likely produce appreciable amounts of new smoke components which might possess undesirable physiological properties.

Re the new German process: The invention of Dr. Bindlg's concerns itself as above briefly described with a method, which eliminates 3:4 benzo-pyren out of cigarette smoke. Through t~e report of ~he US Surgeon General - the so-called TERRY-report -,which appeared ~n Fall of 1964, as well as through the report of the Royal College of Physicians (London, Great Britain) and other Government publications regarding the hazard of smoking, it is withou~ doubt established that 3:4 benzo-pyren is carcinogenic. The el~minatio9 of 3:4 benzo-pyren out of the cigarette .. smoke is therefore of utmost ~mportance to make smokin~ safer.~- .~ ~. In the German urocess an organic compo.undis used, which is sprayed on the tobacco~ As long as tobacco in ~he-course of its processin~ in the plant issprayed anyway no additional equipment has to be added but rather the~organic substance is dissolved.in the normally "used spraying substance.~ The'Cost. for the German substance is very small and only a Very small amount of the substance has to be added to the conventional-spraying fluid, namely: 2 pounds of substance will treat 333,000 cigarettes at a cost of approximately US $3.50.- per 2 pounds of subs tance. Considering the economics and the easinessof application regarding the new German process as well as the overwhelming favorable attitude of the Governments to make smoking "safe~', there can be hardly any doubt chat considering the enormous volume involved in the c%garette industry a highly profitable venture w£11 be built ups.-~..... t~ .

THE LEXING~X)N LEADER Lexington, Ky. Ed. P.5 ]/14/67 BG AHG WSS DSP CS WRL WMB JHS CBW FDR Smoke Gets In You,' Eyes... And Lungs Wednesday marked .the third anni- versary of the Surgeon General's Report on Smoking and Health, the controversial collection of statistics which led to a fed- eral law r, equiring all cigarette packages to state: "Caution: Cigarette smoking may be hazardous to your health." But most Americans still make their jokes about "coffin nails," even though cigarette smoking is extremely harmful to many of our citizens. Many of the peo- ple warned by their doctors about ~,hat smoking will do to them, continue with- out a thought of tomorrow. The Louis Harris public opinion poll, released' the first of this month, showed tha.t only 40 per cent of those questioned were con~ meed that smoking was a ma- jor cause of lung cancer. And although 76 per cent favored the legal caution requirement on cigarette packcges. 57 per cent felt that the warn. ins wvs more than mlequate. Yet. well-trained scientists have found that ~moking is causally related to em. phy~ema, heart disease and cirrhosis of the liver at well as lung cancer. Those persons v'ho should not smoke, who have had warnings from their doctors, should stop now. Also, we should launch a rmtional ef- fort, a serious and meaningful attempt, to prevent youngsters from taking up the Imbit. Fifty years a£o, 42.000 men and $,000 women died of lung cancer. It was a rare disease, then. The tables have shifted and now all forms of cancer make up the nation's second leading cause of death. The National Advlsory Cancer Council has projected thbt ~05,000 people witl die of cancer in the United States during 1967. A grim thought. Since Lexington is the world's .largest hurley tobacco market, it Should be our responsibility to lead the way in develop- ing a safer cigarette and in providing leadership to decrease the-number of deaths which may be Indirectly related to our community's top cash crop. We should not deceive ourselves into offering .economic answers to serious questions of health. We should lead the nation with safer products and should make all people aware of any dangers in using our products.

Dr. Bind~g uses a preliminary ~Titten opinion of the "Bundesanstalt fuer Tabakforschung in Forchheim" (Official German Research Institute for Tobacco) as proof of the success of his process to reduce the benzpyrene content of cigarette tobacco. According to Prof. Schmid, the written opinion is solely based on results of prellm~nary tests, thoroush additional tests will be run in order to verify the r~sults. The final report has not been received. The Scientific Commission recommends to obtain eventually an official report from Prof. Schmid of the Forschungsstelle outlining the final results of the tests. In the meantime, we found out that Prof. Schmld is participa~ ng at a meeting of th~ Commission Scientifique (CORESTA) in Rome. Dr. Weber will 41scuss with Prof. Schmid this matter (Dr. Bin~ig) and also the matter '~trosamines." Dr. Eeurath reports in regard to information received, whereby citric acid is identified as the material of Dr. Bindig's research. Strangely enough, Dr. Bindlg does not call it citric acid but oxy-~y~-propsne- tricarboxylic acid. - /

January 31, 1967 COMMENTS ON THE TECHNICAL REPORT ON CHEMOSOL Pa~e 2~ Par. I It is stated that Chemosol does not survive pyrolization in any form ~ more interesting than carbon dioxide and water. Presumably this means that it is an organic compound containing carbon, hydrogen ~ ~d possibly oxygen. On the basis of minutes of the official German Institute for Tobacco, it is believed that the compound being recommended by Dr. Bindig is citric acid. For example, in the minutes of the meeting of t~e Research Institute, held on October 4, 1963, Dr. Neurath reports that the material which has been used in Dr. Bindig's research has been identified as citric acid. Dr. Bindig however referred to is as oxypropanetricarboxylic acid. Interestingly enough, Lorillard has obtained a patent on the use of citric acid to reduce ciliastatic activity of cigarette smoke. At one time we had s~u~ied the effect of addition of fumaric acid to hurley tobacco and definitely established that the sensory strength was greatly decreased by the acid. It is possible that ciliastasis would have been reduced also but the work was done long before the smoking-health problem emerged. WINSTON cigarettes are now being made with two levels of citric acid. Determinations on the two test samples and on controls will be made for nicotine in smoke, solids, aldehydes, HCN, nitrogen oxides, phenols and polycyclies. We will also determine mildness and perhaps ciliastatie activity at the Industrial BIO-TEST Laboratories, Inc. Page 2, Par. 2 The.feasibility of inhibiting the formation of 3,4-Benzpyrene was not satisfactorily demonstrated by Alvord. In the first place, the article by Alvord deals almost exclusively with the depression of formation of 3,4-benzpyrene during the pyrrolysis of cigarette paper. He ran one experiment on tobacco, using 4.25% ammonium sulfamate a~d obtaf-~d a 50% reduc~0n in 3,4-benzpyrene. We
Page 80: 502076767
2 repeated this experiment recently on WINSTON tobacco rods at 5% ammonium sulfamate level. The cigarettes did not burn on the regular smoking machine owing to retardation of smoke. Accordingly, addition of ammonium sulfamate rendered the cigarettes unsatisfactory for consumer smoking. It was necessary to smoke the treated cigarettes at the rate of three puffs per minute to maintain burning. Under these conditions there was about a 50% reduction in polycyclics. Dr. Jones reports that the taste of smoke was very seriously adversely affected by the sulfamate treatment. ~a~e 3, Par. 3 According to this paragraph, Chemosol is inexpensive. This statement would lend further support to the view that the material is citric acid. ~age 3, Par..4 Chemosol does not adversely affect quality of smoke in panel tests. experience, addition of organic acids to tobacco had the same effect. In our Page 4, Par. 2 Chemosol reduces irritation; this effect would be expected of citric acid. ~age 47 Par. 4 Chemosol effects persist up to 120 days. In our tests, the effect of fumaric acid on mildness decreased on snorage. We interpreted this as equilibration with bases in tobacco. This, again, suggests that the additiye is an acid. Page 4~ Par. 6 Nicotine was r~moved from cigarette smoke c0ndensat~ for animal tests. This alteration of smoke is believed to be unacceptable if one wishes to extrapolate these data to human data where we are concerned with effect of whole smoke. Page 5~ Par..3 It is stated that Chemosol prevents -the formation Of 3,4-benzpyrene in cigarette smoke. The data which are presented later in this report do not substantiate this statement.
Page 81: 502076768
Page 8~ Par. 2 The author states that he used the CF-I mouse (C~.....~rth) inbred. The CF-I mouse is not inbred, but is a random bred mouse sold by Carworth Farms. The CAF-I inbred mouse sold by Carworth was the mouse usually used by Wynder in most of his studies. There is no objection to using the CF-I mouse however, because it is a random bred mouse (Swiss). This strain would also be highly resistant to mammary tumors, yet susceptible to some t~pes of carcinogens. This is not, however, a study on carcinogenesis. The work reported here is simply an assessment of the toxicity of cigarette residues and their apparent reversal by Chemosol; whereas Wynder's work was, of course, concerned with carcinogenesis of smoke residues.~ .~a~e 12~ Par. 2 The author does not mention the volume of sesame oil injected for ten con- secutive days. Neither does he mention the concentration of the residue suspended in the oil. These are most necessary in any description of materials and methods of any scientific paper on toxicity in animals. From viewing the photographs in the paper-~I~~~_-~ the volume injected daily was about 0.5 ml. per day. The results given on page 12 indicate that at the 50 cigarette level the Chemosol plus the residue developed no mortality,' and the residue only produced 60% mor- tality. He does not say how long the oil controls were held, or if they were held for the same period. The I00 cigarette level is obviously a fall'out point (no~ necessarily the threshold). It is assumed from these data (scant as they are) that a'does-response test could be generated with intermediate levels of the residue. These biological data can obviously not be quantitated using the number of ciga- rette residues as the dose. " .............. .page 13 In his results expressing vascular impairment or tissue destruction, the author states that at the 25 cigarette level, the residue alone gave 100% destruc- tion, and no destruction with Chemosol-plus-residue, and 0% destruction for the oil alone. At the 50 cigarette level for which the mice were held for 14 to 16 days, 100% vascular impairment was noted in the residue only, and 80% in the Chemosol-plus-residu~. There appears to be a very narrow limit of does response measured hy this technique. The author also did not mention at the i00 cigarette level if the mice held on the oil, and on the Chemosoi-plus-residue level were held the same length of time that the mice given the residue 0nly were held for.
Page 82: 502076769
It is concluded that protection provided by Chemosol against vascular impairment and tissue destruction is of an order of magnitude of five- to ten-fold. Automatically one would use tissue culture experiments rather than in vivo experi- ments for quantitative determinations. It is believed that in vivo experiments are of little value for quantitative determinations. It is believed that the method to determine toxicity of materials would not be acceptable to workers in the field. It is important to note that the animal test described is a test for toxicity. It should be recognized that it is not to be construed as a test for carcinogenicity although the treatment is designed to reduce 3,4-benzpyrene. If one were testing for carcinogenicity by subcutaneous injections, one would not make as frequent injections as are reported here since 3,4-benzpyrene is known to be quite stable and would remain at the site of injection. Experiments in the report include development of analytical procedures for 3,4-benzpyrene and determination of 3,4-benzpyrene in the smoke of treated and untreated cigarettes. In essence, page 24 Shows a calibration curve. The four points fall on a straight line; however, the values which were obtained for the knowns and unknowns fell in the low part of the curve. There could have been serious dis- continuity at the low part of the curve, particularly in the presence of impurities. The extension of the straight line is believed to be an unwarranted extrapolation. .Page 371 Par: I~ Page 3@~ Par. I; Pa~ 39~ Curve at Bottom of Pa~e We can say that the final statement made on page 38 may be correct but the final sentence on page 37, par. i, may not be necessarily " ~ correct because of interfering subs tances • ~ .Page. 44~ Last Peru A total of 5.56 micrograms should have been found in the residue from 200 untreated cigarettes. As can be seen, only 3.2 micrograms were recovered which is~quite an unsatisfactory recovery from these 200 untreated cigarettes.
Page 83: 502076770
Pa~e 49~. Par. 2 This is the analysis of the smoke from treated cigarettes. If no 3,4-benz- pyrene had been present then 3.16 micrograms should have been found. However, only 1.7 micrograms were recovered which is about one-half (3.16) of the spiked amount. Obviously, his recoveries are quite unsatisfactory, so how can one regard this as an analytical procedure. Looking at all the data presented in this report, one might conclude that Ehere is a hint that the $,4-benzpyrene content of treated cigarettes is lower. If one were to assume that Chemosol is citric acid, then the addition of an appreciable amount to the tobacco would, change the burning characteristics of the cigarettes. It is conceivable that it would depress the formation of 3,4-benzpyrene to a measurable extent. Even if 3,4-benzpyrene were reduced by 50%, the addition of citric acid could not be exploited commercially since this is not the only alleged carcinogenic factor. It is highly probable that Chemosol would produce a very marked effect on the nicotine content of smoke if it were, indeed, citric acid. A marked reduction af nicotine in smoke however would not be accept~Dle for smoking purposes since a certain minimum of nicotine is needed for physiological effect.

JOHN C. WATTS ouee e! tprt tntatibee COMMITTEE ON WAY8 AND MEAN~ 31 January 1967 M~. Henry Ramm Vice President & Ceneral Counsel R. 3. Reynolds Tobacco Comp--y Winston-Salem, North Carolina ._+ Dear Mr. Rmm: You will remember that I told yon of my own personal experience after s~oking about 100 of the "Chemosol" treated cigarettes when you visited our office several days ago. My background is in engineering and construc- tion and covers a period of approximately 30 years. During this period I have been a very heavy cigarette smoker and had acquired a so-called "morning cough" which was my constant companion. After smoking the treated cigarettes for only one day, I awakened the next morning without the slightest cough ..... and this continued until I had exhausted the supply on hand. For approximately 10 days, I smoked my reg- ular cigarettes (a popular filtered brand) and my cough returned iumediately in its usual form. Two days after you were here, I obtained another supply of the "Chemosol" + treated.cigarettes,- -I have experienced exactly the same result and my cough has completely disappeared. While I have no s~ientific Jus- tification, I knov without doubt that something asso- ciated with the treated cigarettes causes me to+stop coughing during the entire time I smoke nothing else• This is a factual statement on my part that I thought you might like to have - because I have nothing to gain or lose by the success or failure of the "Chemosol" process •

A REVIEW OF "TECHNICAL REPORT ON CHEMOSOL - A FUEL ADDITIVE FOR CIGARETTE TOBACCO" The following remarks and questions refer to the unsigned and undated document entitled "Technical-Report on Chemosol - A Fuel Additive for Cigarette Tobacco." Industry scientists representing the six major cigaret£e manufacturers have thoroughly studied the subject report. They have experienced a great deal of difficulty in establishing the validity of the stated conclusions, largely because of the many pertinent and crucial points which have been omitted in the report. From the very beginning many unsubstantiated claims are made. Many of these involve points which could be resolved by well designed experiments which unfortunately were either not performed or are omitted from the report. Consequently, the industry scientists at this point in time can only formulate some general impressions of the work and then submit a list of specific and detailed questions, which if answered will permit a more~.complete evaluation. GKNE RAL IMPRESSIONS i. BIOLOGICAL SECTION: The reported biological experiments appear poorly conceived since the results and their implications do not substantiate conclusions concerning the carcinogenic potency of smoke from treated and untreated b~207 ~779

- 2 - cigarettes. The authors have used, as a means of bio-assay, an injection technique in CF-I mice. As far as we know there has been little, if anything, in the literature concerning the relationship between ulceration at injection sites and benzo-(a)-pyrene (BaP) content of the injected materials. The authors make no statement regarding their injection technique - which in itself could Be critical - in the production of various skin reactions. Incidentally, the use of sesame oil in injection procedures has been criticized severely. .This material is poorly absorbed and is not regarded as suitable carrier. The introduction of "Chemosol - fuel additive" is stated by the investigators to prevent the formation of BaP. Consequently, a relationship between BaP content of the injected materials and the bio-assay results must be established. -No experiments were reported in which BaP in sesame oil was injected into the mice. Further, these studies are based on the precept that a relationship exists between ~e concentration of BaP in cigar@tte smoke condensate and its tumorigenicity. References to the publications of Alvord0 et. al., Wynder, et. al., and the U. S. Surgeon General's Report are given to support this view. More recently, P. Lazar et. al., (Journal of the National Cancer Institute 3__~7(5):573-579, November, 1966) clearly vitiate the hypothesis of a quantitative relationship between BaP and mouse skin activity, including carcinogenicity of smoke condensate. 50207 6780
Page 92: 502076781
- 3 - Finally the "Chemosol Report" has been submitted to an independent and reputable biological consultant who has made the following statement: "The biological data consists of observations on local necrosis at the site of administration and systemic toxicity (growth. curves and mortality data). There is no information on carcinogenicity. These tests were done on a residue of the condensate from which it is stated that 'only the nicotine is removed.' I find this hard to believe because they have apparently used a sulfuric acid wash step which will pull out other basic molecules as well as nicotine and might have caused changes in what was left. "The ulceration experiment appears to indicate that the residue from the treated tobacco condensate is less active in this regard than the untreated. I don't know what this means or would show in terms of possible effects on lungs when the treated smoke is inhaled. "The systemic toxicity data are somewhat peculiar in that the treated smoke mortality was not different from the untreated at the I00 cigarette dose (509 mortality in both) but there was a difference (609 mortality in the untreated, none in the treated) at.a 50 cigarette dose. The failure to find a difference at the i00 cigarette level suggests that the difference at the lower level may be an artifact. ~ "Overall, it is clear that the biological work is very preliminary and does not provide an adequate base on which to evaluate the chemosol treatment as promising or not." In summary, it may be stated that the biological experiments performed have in no way demonstrated that there is a difference in the tumorigenic or carcinogenic activity of smoke condensate of treated and untreated cigarettes. The number and kinds Of comparisons were 50207 6781
Page 93: 502076782
- 4 - inadequate, the techniques may be inappropriate, and no statistical treatment of the data, as meager as it is, has been offered. CHEMICAL SECTION: It is extremely difficult to appraise the analytical chemical work performed because no two experiments were carried out on identical samples in the same manner. At the start great variation could be expected in the smoke delivery from cigarette to cigarette because the cigarettes were individually fabricated on hand operated machines. No information is givenregarding the quantity of particu- late matter collected on the Cambridge filter or the amount of condensate collected in the cold traps. In a procedure as complex as the fractionation of cigarette smoke condensate - involving repeated extractions, partitions, various forms of chromatography - itis essential that knowledge be had of the amounts of material initially collected as a sample. The techniques used for the isolation of a fraction for ultimate" "spectrophotometric analysis to determine BaP must be carefully controlled and rigidly adhered to, sample after sample, in order to determine reproducibility before any comparison between two supposedly different samples can be made. This principle, funda- mental in analytical chemistry of this type, is entirely lacking in the reported experiments.

PERRY B. HUDSON, M. D. 117 EAST 71ST BTRIrL'T April 21, 1967 The Honorable John C. Watts House of Representatives Washington, D.C. Dear Congressman Watts: Initially it should be emphasized that the first Chemosol report to you included what were at the time considered to be the salient points in the investigation by January II, 1967. It was not intended to be, and is not, a compendium of all the experimental work and observations. With this letter you are belng brought up to date. In the past, investigations of this sort satisfied only a segment of the institutions and individuals who are working in the field of tobacco smoke toxicity. The methods and equipment employed in making cigarettes, mechanical smoking,condensate handling (collection, storage, etc.), separations protocol, recovery deter- minations, identification techniques and control systems -- these factors still are viewed in various ways by different laboratories. However, the combination of chemical and biological evidence from Chemosol experiments overwhelmingly indicates that cigarettes treated with Chemosol are safer. • The industry scientists are now being given information on the alteration in tumorigenicity provided by the fuel additive, Chemosol. It is unfortunate that these experiments were not given to them before they evaluated the original report. In any event, we have determined differences in the biological effects of smoke from cigarettes treated with and without Chemosol. Secondly, through analytical chemistry, observed differences are explained. All of the biological data on tumor induction were wlthheld from the original report in order to obtain, wi~h discretion, the opinions of experts with great experience and professional stature In this field. The approach used in these experiments dictates the blologlcal importance of the quality, rather than quantity, of smoke condensates. Therefore total gravimetric values for condensates as a particular point have not been extensively investigated with and without Chemosol; no statistically significant comparison has been attempted. Experiments requiring the paintingof rodent skln with tobacco smoke condensates have in recent years received much attention. ~uch experiments are in progress now at the High Tot Laboratories. - 1- 50207 6790

The Honorable John C. Watts - 3 - April 21, 1967 used, and there are no discernible differences in physical character- istics in the finished products. Tobacco weight per cigarette is constant. The time required to smoke each batch of 500 cigarettes has been less than 24 hours in all experiments. Smoking machines operated on a continuous basis will smoke several thousand per 24 hour period. Condensates are immediately extracted and the protocol of separations chemistry initiated. Measurements of the particulate matter removed or retained at each step are not routinely made. Acid washes are not always used; recovery experiments with known amounts of hydrocarbons (e.g. benzpyrene) yield total recovery on the one side and zero on the acid side; surveys for other aromatic hydrocarbons (of varying molecular structure and with different numbers of rings) also yields negative results on the acid side. Sesame oil, lard, croton oil, acetone- these and other carriers have successfully been used for benzpyrene production of experimental tumors; implanted smoke condensates with no carrier or solvent have been used also; sesame oll produces no tumors itself and allows for slow, long-term absorption of condensate with well-documented micropathological changes attributable to the oil alone. The fate ~f every animal in every experiment is determined. At the time of death, regardless of apparent cause, each animal is preserved for complete autopsy with gross and microscopical pathological study. The C F-I mouse was chosen in consultation with colleagues in other institutions and with the advice of scientists at Carworth Farms, a leading producer of strains of animals for particular experimental purposes. The C F-I strain is not the only mouse used, nor are the experiments confined to mice. Both males and females have been used for all experiments; no regard to seasonal factor has been given in weight- gain experiments because of the short duration involved (e.g. 10-day period of injection); however, these mice are kept, not sacrificed, so that long-term results may be obtained. Housing conditions for these animals are identical to those found elsewhere in :the region - (Columbia, N.Y.U., etc.) and found acceptable by leading authorities. Weight gain studies were made only at a dosage level consistent with survival of all animals; to do otherwise would produce artifacts derived from complex metabolic alterations attendant to death from overwhelming toxicity. No statistical technique was either required or employed for weight gain studies used as part of a toxicity survey, considering the results obtained. Volumes of treated and untreated residue injections at each level were identical, as they were for 25, 50 and I00 cigarettes. The

.-'~'~c llonorable John G. Watts - 4 - April 21, 1967 technique of injection is shown in accompanying photographs, as is the "painting" technique. All dying animals receive complete gross and microscopical autopsy evaluations. Microscopical changes found in local tissue destruction of ulcerating lesions from untreated tobacco are the result of arterial occlusion. (This observation was consistently made during toxicity screening.) It does not occur when Chemosol is added to cigarette tobacco. While no extrapolation from this observation to human pathology is made, failure to develop these changes with Chemosol condensates is further evidence of the total safety factor involved. CHEMICAL SECTION: Information is available on the pyrolytic'decomposltlon products of Chemosol. For security reasons this information is withheld. There is no significant biological reaction to these end-products. The appearance, aroma and flavor of cigarette smoke is not noticeably altered by Chemosol, although the composition of the smoke is changed in some ways (e.g. benzpyrene content). The quantity of Chemosol required to produce the desired effect is known. Parameters for standardized smoking have remained unchanged through experiments in which different smoking machines have been used; only the 40-port machine has been used for this work during the past several months. This machine is similar to each of the smaller machines previously used, and except for size is almost identical to the 20-port machine supplied to us by a member of the Tobacco Institute. Experimental smoking is conducted continuously and condensates need not be stored. It is acknowledged that both hexane and cyclohexane are good polycyclic hydrocarbon solvents. Familiarity with methyl cyclohexane prompted, in part, its selection in the High Tot Laboratories. Reagent grade chemicals are used in extraction work and spectral grade for analytical work; further purifications are not routinely required; spectra are run on solvents, however. In the Grinvner method and with modifications in it, "pure" benzpyrene is obtained from the last column. Between 375 - 395 mu the amounts of any substances contaminating the benzpyrene would be insignificant. No spectrophotometric examination is made of the "B P fraction" from chromatography of the treate8 smoke sample on the second column (p.36) because of the large quantity of interfering 6"/93

The Ronorable John C. Watts -5- ~prll 21, 1967 impurity. This has been experimentally demonstrated by adding pure B P and observing how the impurities obscure it for detection. Many experiments have been done In whlch identical procedures were followed for treated and untreated samples of smoke condensate. Consistently negative results for B P in the Chemosol treated samples has prompted the further search as described in the prior report. Multiple malignancies derived from experiments involving hundreds of animals denied protection of Chemosol, against zero in the Chemosol group, provide positive evidence of protection against tumor formation by the use of this fuel additive. More precise instrumentation is available for the final detection of the presence of benzpyrene. However, the amount which could possibly be detected is in a range well within the error inherent in the separations methods. Furthermore, biologically, there is no understandable difference between absolute zero B-P values and those which are practically zero. This information, plus the materlal previously presented to you, answers all of the questions submitted to us, except in those instances in which answers are wlthheld for security reasons. The per- formance of numerous types of chemical experiments and blologlcal studies involving thousands of animals, have resulted in the accumulation of documented evidence beyond that necessary to substantiate the conclusions stressed here. This data is available, and interviews at our laboratory ~_may be the mostexpedient means toward total cl-a~iflcatlon. -. .Very truly yours, Perry B.

Eva~uatlon o£ Results= the anin~als receiving no protection from Chemosoi in :he cigarette tobacco produced a high percentage of ,~...iignanc, anaplastic =umors. The Chemosoi- treated tobacco condensates produced no malignant turaors. The statistical significance of these finding~ therefore a~sumes grca~ i;uportance. To arrive at the abstract significanc~ of these experlr.en~al results, it was necessary to determine ~he mathematical probability of obtaining the same results (within specifiei, acceptable percentile variation) should the experiment be repeated. Such reproducibility of the experiment gives practical significa.nce and value to =he findings. There are several acceptable means of estimating statistical significance of results in biological ex~erimentatlon of this type. We have elected the szringent z~ethod e=:pioying Fibber's Exac= Test. In addition, the competing risks i~vo!ved prompted evaluation under the most pessimistic hypothetical conii=ions consistent with observed facts. The overall probability of .004 indicates that Chemosol cannot be disregarded as the cause of a~ ferentiel in nm]ignant rumor production in ~he ~obacco snake condensa~c~ ~:.is concept i~ corroborated by the blos~a~.~ica! analysis of Herbert Levine, Eead of Bios=atistfcs, >:oncefiore Hospital an& Medical Ce~er, Xew York, whose flnilngs are attached =o ~his report.

U;-,der ells se~ of circumstances, the observed resu%ts ar~ not likely considerin~ the [:no~:n role of tobacco sn%oke condensate as a ca~*cinogen. Group B should have had some ~u~.ozs if the latter situation was true. and Chemo$ol made no d if feb'ante. ~:~hile the practical si~nifica:.c~ of the experiment i& quite obviou~ tests of sta~isticai signif" -'- ~re TM or'Cot. One ought to .... ~.. ob~,.~no the ou~.~u u~sui'~& upon replicating the ex:~eri- ment under the assumption that ChoL~sol really ~d~ no difference in production of malignant ~umors. i analy~cd the results in ~::o ways zince thare was an elc=~ant of competi:.g risks involved, a concept which i ~,,ill explain belong. In my first approach~ I analyzed the results in terms of the original groups of I00 mice each. U~ing Fisher's Exact %'est, the probability of obtaining the observe/ :-ares of malignant tun:or production (16/100 in group 0 and 0/i00 in Group L)~ under ,~h~ hypothesis that Che.~oso! actually had no effect~ was ca!cula~ed to be .000007, or 7 in a million. In terms of the development of Fibrosar¢omas, the probability was calculated to be approximately 3 in 1,000, o~- .003~. to be exact. As for ~he con,paring risk concept, consider the fact that the A n.ice in group B than died from o~her cau~s might have developed malignant tun~.ors if they had lived longer. To raise this factor ~nto account, I arranged ~he data to provide the most unfavorable possible results for group B and the most favorable possible results for ~[roup C. I assumed ~hat ~he $ mice dying in group B wiZhout evidence of a "__nor had lived longer and deve!op~d tumors w~,~e the 3 ":" dving from other causes in ~rou~ C would haw within a year; ~:~ r~.-~ lived and not developed a t .... ~u.

- 2 - Using these data and applying Fisher's Exact Test, the probability of obtaining the" assumed results, or results which were more extreme, was calculated to be .00~ with respect to all types of malignant tumors. If only Fibrosarcomas are considered, the calculated probability is .186, which would not be significant if the conventional .05 level is used to indicate statistical significance. The analysis discussed above represents what I was able to do in a limited amount of time. I am sure that the data could be treated in numer- ous ways using different assumptions..However, considering the observed results, other tests of statistical significance are likely to reject the hypothesis that Chemosol had no effect on the production of tumors. Thank you for the opportunity to share your interesting findings. Sincerely yours~ ~erbert S. Levine, Sc.D. Head, B iostat ist ics Department ESL:ss J

SUMMARY Since shortly after its discovery in 1913, vitamin A has been considered by biochemists and physicians as a nutrient neces- sary for the health of the ephlthelial linings of the respiratory tract. More recently, vitamin A has been shown to be effective in preventing bronchogenlc carcinoma induced in hamsters by benzo(a)pyrene, and in preventing and reversing precancerous tumors, "papillomas," induced on the skin of mice by a similar carcinogen, 7,19-dimethylbenz(a)antracene, called "DMBA." The Council for Tobacco Research-U.S.A. is one group sponsoring re- search into a connection between dietary factors and carcinogenesis. Known since the time of Hippocrates to be needed for the prevention of night blindness, vitamin A is now recognized as hav- ing a more vital role in human health. Its lack leads to the over- production of keratin, a horny substance that makes up skin, feathers, horns, hoofs, and fingernails. This abnormal keratini- zatlon is found in various diseases of the skin, mouth and genito- urinary organs -- as well as the respiratory tract. Leukoplakia, white lesions in the mouth, is one of these diseases. Leukoplakia is also the most common precancerous lesion. The treatments for this disease which if untreated often develops into cancer, are surgery and large doses of vitamin A. The anti-cancer activity of vitamin A has been discussed since the 1920's. The vitamin may prevent or attack cancer and the precancerous states in many ways -- biochemical and mechanical. -I-
Page 135: 502076992
Epithelia and mucous membrances, made healthier by the vitamin, have been shown to be less prone to cancer. Abnormal keratini- zation, a stage in the sequence which can lead to many types of cancer, is prevented and reversed by vitamin A. Cilia, the micro- scoplc hair-like projections of the cells lining the bronchi, can be saved from destruct'ion by vitamin A, enabling them to continue their natural mechanical functions: trapping and removing dirt, irritants and carcinogens. The benzene compounds may be detoxi- fled metabolically by large doses of vitamin A. Reporting on his latest findings, confirming earlier findings, Umberto Saffiotti, M.D. of Chicago Medical School, explained his working hypothesis to last April's meeting of the Federation of American Societies for Experimental Biology: Vitamin A and a carcinogen aim at a "common target," a human process now unknown. The carcinogen initiates cancer, while vitamin A prevents cancer. James Olsen, Ph.D., a Rockefeller Foundation researcher, theorized at the same meeting that cells are more susceptible to cancer when they are dividing abnormally; and vitamin A prevents this abnormal cell division. At the American Cancer Society's Science Writers Seminar, last April in Palm Beach, Florida, Ronald Davies, Ph.D., a bio- chemist at Temple University's Skin and Cancer Hospital in Phila- delphia, explained that vitamin A, by speeding up natural skin growth, gives normal healthy epithelial tissue a "competitive advantage" over cancer. --~--

The benefits of vitamin A are not merely local, even though vitamin A has been used for years by dermatologists for various skin diseases. It also acts through the bloodstream when ingested orally or administered intravenously. Getting a biologically active agent into the bloodstream where it acts systemically can be accomplished another way -- by inhalation. Presently adrenalin (epinephrine), a stimulant, and amyl nitrite, for coronaries, are inhaled for their systemic effect. Nitroglycerine tablets, also for heart ailments, are absorbed into the bloodstream when placed under the tongue. Inhaling vitamin A would be akin to administering it intra- venously since the digestive system would be by-passed and the vitamin A would get into the bloodstream by passing through the highly vascular areas of the.tongue, bronchi and windpipe (trachea). A way of transporting the vitamin A for deposit on these blood vessels is via the natural moisture base of tobacco smoke. In addition to exerting some protection against the onset of bronchogenic carcinoma, vitamin A, by keeping the lung's epithe- lial lining healthy, may prevent emphysema. Some researchers have even reported that vitamin A is necessary in the prevention of athlerosclerosis. Normally vitamin A is fat-soluble -- and not water-soluble. But it can be made water-dispersible. Water-dlspersible vitamin A is available at any drug store for sale over the counter.

A device releasing vitamin A into the mainstream of tobacco smoke would assure an adequate supply of vitamin A to the respira- tory tract and bloodstream of smokers.

VITAMIN A AND THE EPITHELIA Hippocrates, probably the. first physician to record the use of vitamin A in treating disease, prescribed "an abundance of liver as a remedy for night blindness." (I) This association between vitamin A (found in liver in high amounts) and vision is well known, however, the nutrient has other roles in human health. James Olsen, Ph.D., a Rockefeller Foundation researcher and noted vitamin A expert, said at the Federation of American Societies for Experimental Biology annual meeting in April, 1967, that even though vitamin A was one of the first vitamins to be discovered, its action was still as mysterious to the researchers as the ac- tion of some of the "newer" vitamins like vitamin E. He, and other vitamin A experts on F.A.S.E.B.'s vitamin A committee, agreed that medical clinicians and researchers have in the past two years de- monstrated renewed interest in vitamins, but especially vitamin A. Vitamin A was apparently discovered in 191B simultaneously by two groups of researchers, McCollum and Davis, and Osbourne and Mendel.(2,B) Among the first signs of a deficiency in the then unnamed food factor were skin diseases, impaired vision and actual damage to the eye. (4) But a more vital role for vitamin A soon became apparent: a role in maintaining the" health and integrity of the protective ephithelial linings of the body, including the linings of the trachea, bronchi and bronchloles of the respiratory tract.
Page 139: 502076996
The Heinz Handbook of Nutrition, published for the H.J. Heinz Company and used by the food and drug industries generally, as well as by professional nutritionists, explained this early recognition of the multifaceted role of vitamin A. Soon after vitamin A was discovered as a necessary ingred- ient in the human diet, scientists noted two specific eye diseases caused by a deficiency of the nutrient. One of these diseases involved the drying and roughening of the cornea of the eye, or "xerophthalmia." The other, "keratomalacia," involved a later state of ~he same disease process, characterized by a fluid re- tention (edema), presence of abnormal substances (infiltration), and necrotic softening of the cornea sometimes followed by perfora- tion, the accumulation of pus and inflammation. (6) But in the diagnosis and treatment of patients with the vitamin A deficiency diseases, xerophthalmia and keratomalacia, physicians noted disease symptoms affecting the mouth, throat and lungs. The Heinz Handbook of Nutrition stated on page 147: Early clinicians frequently commented on the dryness of oral, nasal and pharyngeal membranes, hoarseness, husky voice and dry cough in pa- tients with keratomalacia; also the frequency with which respiratory infections, chiefly pneu- monia, were associated with acute phases of the disorders that constituted the primary cause of deathcases, o~6~ntreated or inadequately treated Rather than a nutrient with many independent and unrelated functions, v~tamin A became recognized as a nutrient needed by the one part of the body affected by the vitamin's deficiency -- -6-

the epithelial tissue. This tissue, the epithelium-- coated with a film of mucus when healthy -- lines the organs open to "the outside world," such as the eye, alimentary canal, respira- tory tract and genito-urinary tract. (7,27) As expressed by one researcher, "Aside from its role in growth and vision, the vitamin is important in maintenance of epithelial structures othe than the eye." (8) This importance is described in The Heinz Handbook of Nutrition on page 74: Vitamin A is essential for the integrity of epithelial tissues and normal growth of epithelial cells. Deficiency of vitamin A results in atrophy of the normal epithelial cells. Deficiency of vitamin A results in atrophy of the normal epithelial cell layer followed by proliferation of the basal cells and metaplasia to a stratified, keratlnized epithelium. In mucous membrances, secretory function is deranged and eventually obliterated. These changes may occur in the mouth, the respiratory tract, the urinary tract, the female genital tract, the prostate and seminal vesicles, and in the eyes and paraocular glands. In non-secretory, protective epithelium, vitamin A deficiency results in hyperkeratinization. Hyperkeratinization is the excess of keratin in epithelial tissue where some keratin is normal and necessary -- such as the skin. Analogous to hyperkeratinization of the skin is the pro- duction of keratin where keratin is neither normal nor necessary under normal conditions. This occurs in the mucous membrane epithelia of the respiratory tract and the urogenital (genito- urinary) system and manifests itself as keratinizing metaplasia. -7-
Page 141: 502076997A
Either too much keratin or keratin where it shouldn't be is the common denominator of most vitamin A deficiency diseases. The unwanted keratlnlzlng or hyperkeratlnlzing process is a mor- bid change in epithelial tissue and can be reversed by ample doses of vitamin A. Many of the diseases involving keratinization or hyper- keratinization are precancerous diseases and modern scientists have considered the keratinization process significant in the search for links in a chain of pathological events that end up as cancer. Not only does lack of vitamin A cause the over-production of keratin, the nutrient, when administered, can reverse this disease process and establish equilibrium with the right amount of keratin being produced. (9) Vitamin A also protects against abnormal changes in the cells, called "keratinizing metaplasia." As The Heinz Handbook of Nutrition continued on page 209: The basic pathology of avitaminosis A (vitamin A deficiency) is hyperkeratlnization of the skin at large and keratinizing metaplasia in the linings of the respiratory, gastrointestinal, and genito- urinary tracts and endocrine, salivary, sebaceous and lacrimal glands. -8-
Page 142: 502076998
KERATINIZING METAPLASIA IN THE RESPIRATORY TRACT The respiratory tract is particularly dependent on vitamin A, as those early clinicians discovered while treating keratomalacia of the eye. In discussing vitamin A deficiencies, pioneer nutrl- tionist James S. McLester, M.D., wrote on page 305 of Nutrition and Diet in Health and Disease: Diseases of the respiratory tract are common. The mucosa of all parts of the tract becomes keratinized, but even before this has occurred, there are, no doubt, profound disturbances of function. Because of the readiness with which accumulations of keratinized cells become in- fected, this metaplasia of the epithelium of the respiratory tract and communicating cavities may lead not only to colds and bronchitis but also to sinusitis, otitis media, bronchiectasis and pneu- monia. This, no doubt, explains the frequency and high mortality of pneumonia in in~ants who suffer from vitamin A deficiency. (10) Keratin and keratinizatlon must be discussed whenever the pathology of vitamin A deficiency or "hypovitaminosis A," is con- sidered. Vitamin A deficiency causes the replacement of many different single layered epithelia by a stratified "keratinizing metaplasia." This is explained in detail in Some Aspects of Vitamin A Metabolism by J.S. Lowe and R.A. Morton, Volume XV in the series, Vitamins and Hormones: Atrophy of the epithelium concerned, .reparative proliferation Of the basal cells, and growth and differentiation of the new products into strati- fied keratinizing tissue. Regardless of the original function and structure of the region, this replacement epithelium is identical in all locations and comparable in all its layers with epidermis. -9-
Page 143: 502076999
When the vitamin A deficiency is brought to an end% the epithelium of each region returns $o normal both in morphology and function. (177 In Volume of of The Vit~amins: Chemistry, Physiology and Pathology, edited by W.H. Sebrell, Jr., M.D. of Columbia and current chairman of the Food and Nutrition Board of the National Academy of Science's National Research Council, and nutrition expert Robert S. Harris, the effect vitamin A deficiency has on the respiratory tract is explained on page III: Keratinizing metaplasia of the entire respiratory tract~ nares (nostrils) to bronchioles, occurs early. Cough is an early symptom in infants. Atrophy of the epithelium and-loss of ciliary action even before replacement by keratinizing epithelium favor bacterial invasion, and hence lobular pneumoni@ h~s been a frequent immediate cause of death. In the early days after its discovery, vitamin A was called the "anti-infective vitamin." Reason for ~this reputa- tion was the nutrient's role in maintaining healthy epithelia in and around the respiratory tract. On page 76 of the l~th edition of Nutrition in Health and Disease, Lenna F. Cooper, Sc.D., wrote: When vitamin A is deficient, the membranes lining the nose, the throat and other air passages, the alimentary canal and the genito-urinary tracts show changes in the epithelial cells known as keratinization. Wherever these tissue changes occur, the natural mechanism for protection against bacteria or other foreign substances is impaired, and the tissue may easily become infected. Clinical observations show that normal mucous membranes lining nose, throat, -i0-
Page 144: 502077000
sinuses and ear passages are the best defense aEainst infections and that adequate vitamin A is an important factor in maintaining the normal functions of these membranes. From these findinEs came the term anti-infective. This was not reallM Justified, because the function of this vitamin is really the mainte- nance of normal epithelial cells that. naturally afford the best phys$olQEic protection aEainst bacterial invasion. (ii) Keratinization of the respiratory tract due to a vitamin A deficiency can become so clinically acute that such serious lung disorders as blockages of small air passages, the bronchioles, and lung collapse (atelectasis) have resulted. (12,25) -Ii-

EPITHELIAL TISSUE: "THE BODY'S FIRST LINE OF DEFENSE" In describing the epithelial lining of the respiratory tract, in the countless articles on vitamin A, the experts keep using the phrase "the body's first line of defense." This "first line of defense" is protected by vitamin A. (18,19,20,29) For example, Paul Gyorgy, M.D., world-renowned nutritionist and professor at the University of Pennsylvania School of Medicine in Philadelphia, called vitamin A "the epithelium-protecting vitamin." (21) It protects by preventing the replacement of normal cells with a stratified epithelium. (23,30) L. Jean Bogert, Ph.D., summed up the many ways vitamin A is necessary for the epithelial health on pages 264 and 265 of his book, Nutrition and Physical Fitness: One of the chief functions of vitamin A is to maintain the health of epithelial tissues, namely the skin and membranes that line all passages which open to the exterior of the • body. When deprived of an adequate supply of vitamin A, these tissues undergo changes that lead to a peculiar type of horny degeneration called keratinization. Damage to the mucous type membranes that line the mouth, throat, nose and respiratory passages is one of the earlier effects of vitamin A lack. In addition to general de- terioration of the cells, these membranes lack their normal secretions, and there is loss of the little filaments called cilia, which, by constant movement, aid in keeping the membrane surface clean. Probably vitamin A shares with other vita- mins in promoting health of tissues and is 'anti- infective' chiefly in the sense that it~helps to keep healthy the lining membranes that are the 'first llne of defense' to prevent entrance of bacteria into the body. If there has been previous -12-

deficiency of this vitamin, the diet, extra doses of it, will be helpful in rebuilding stores of it in the liver and restorin= damaged epithelial tissues to health.'T22) Some researchers have even reported that vitamin A may prevent the onset of athlerosclerosis. (86) -I3- 0
Page 147: 502077003
PRECANCEROUS DISEASES Other diseases involving areas of the body other than the respiratory tract respond to vitamin A therapy. They, too, should be discussed because some of these diseases are precancerous. Also, all involve keratlnization of the epithelia: that process which can result from a vitamin A deficiency and which under certain conditions can be reversed by vitamin~ A. The presence of keratin is used by pathologists when, by microscopic inspection of tumor tissue, especially from the lung, they seek to determine if the specimen is or is not malignant. Metaplasia (changes in cells) may indicate a "malignant transfor- mation," but to diagnose epidermoid bronchogenlc carcinoma (squamous cell carcinoma) microscopic study reveals keratinized cells. "The outstanding feature" of epidermoid bronchogenic carcinoma (squamous cell carcinoma), one text writer said, "is the presence of keratinized cells." (26) Keratin flakes are observed when breast carcinoma is examined under magnification. (32) "Keratinization is freely present, and numerous masses of dead horn, surrounded by large foreign-body giant cells, occupy the stroma (structure) in ovarian carcinoma." (34) In addition to the wealth of scientific literature on vitamin A and the prevention and reversing of abnormal keratinization and on vitamin A and the prevention and treatment of specific diseases involving abnormal keratlnization, such as leukoplak~a, the most common precancerous lesion, there are articles and textual -14-
Page 148: 502077004
references to a more direct association between vitamin A and cancer. But since most of the literature shows vitamin A's ef- fect on the precancerous state, the sequence from normal, healthy tissue to malignant tissue is germane. In a discussion of this sequence the terms "neoplasm," "precancerous" and "premalIEnant" are used. Stedman~s Medical Dictionary, (B3) on pages 1214 and 1215, defined "precancerous," "premalignant" and "precancer": A lesion from which a malignant neoplasm is presumed to develop in a significant number of cases. (Emphasis ~rovided) And "neoplasm", on page 1006, as: ... new growths not only in the sense of the rates of reproduction of cells, but also from the point of view that the process of neoplasia may result in types of cells that are vastly different from those in the normal tissue of origin. For example, neoplastic cells are fre- quently invasive, and may even grow when trans- planted into other species. On the basis of cytologic and histologic, or the clinical course, or both, considerations (neoplasm) may be sig- nificantly classified as malignant or ben__~ (and also intermediate forms) . . ._ (emphasis theirs) Admittedly, some of the lesions that make up the American Cancer Society's seven danger signs may never become malignant, but enough do to warrant concern when noted. Although experts still do not know the exact nature of carcinogenesis, they generally agree that cancer does not appear instantly but only after cellular changes. At a precancerous stage this progression can often be reversed by vitamin A. (35) -15-
Page 149: 502077005
Early detection and treatment can and, in fact, does prevent cancer. According tothe United Nations World Health Organization, (36) "(1)t would seem ...that the majority of human cancer is potenti- ally preventable." The report of a W.H.O. expert committee stated that one way to "control" cancer is the recognition, diagnosis and treatment of the "precancerous state." On page 7 the committee says: The idea of a "precancerous state" came originally from dermatology - that a correlation exists between certain abnormalities or lesions of the skin and the subsequent appearance of a local cancer. It seemed reasonable to infer that the prior skin condition, while not itself neoplastic, predisposed the affected tissue to subsequent cancerous transformation. The diagnosis of the precancerous state is valuable because the immediate treating and curing of the precancerous state will often prevent the development of cancer. On page 9: The therapy of precancerous lesions forms a corner- stone of cancer prevention. Such therapy should be undertaken as soon as possible after diagnosis, should be adequate, and should be subjected to rigid follow-up. The training of the medical pro- fession in this subject is, perhaps, one of the more important current practical aspects of cancer prevention. It is most urgent that such training as is now practised in certain countries should be made world-wide. Squamous cell epithelloma, a form of squamous cell carcinoma, follows diseases involving the excessive keratin production .(37,42) The incidence is frequent enough to warrant this note on page 159 of The Practitioner's Illustrated Dermatologist by Howard Behrman -16-
Page 150: 502077006
of New York Medical College and Theodore A. Labow, M.D. of Columbia | Presbyterian Medical Center: Squamous cell carcinoma may be preceded by leukoplakia, senile (actinic) keratoses, and scarred or ulcerated lesions of many varying origins including radiodermatitis. These lesions grow much more rapidly than basal cell epitheliomas and often metasta- size. The degree of malignancy, however, varies from lesion to lesion. Studies, cited in the Surgeon Generalls report, Smoking and Health, show that the epithelium of the tracheobronchial tree of cigaret smokers undergoes changes similar to the changes caused by a deficiency in vitamin A. These changes are (a) loss of cilia, (b) basal cell hyperplasia and (c) the presence of atypical cells. (38) Some studies have indicated that the cilia of non- smokers remains healthier than the cilia of smokers.(BS) And vitamin A maintains the health and integrity of the cilla.(35'28) Concluding the discussion on the changes in the ciliated c~lls attributed to smoke, the report stated that these lesions are premalignant. (38) Back in 1937, Edwin J. Simons, M.D., in his book ~rimary Carcinoma of the Lung, wrote about the sequence from a normal respiratory trsct to one with cancer-like growths. On Page 91: According to the information at hand, the effect on the bronchial mucous membrane of the diet, and especially that of a diet contaluing little or no vitamin A, has not been fully determined. Wohlbach and Howe kept white mice on a diet without vitamin A and found metaplastic changes in the uro- genital epithelium. Also, the bronchial epithelium -17-
Page 151: 502077007
began a marked transition involving the basal cells and even changed itself in isolated areas to Keratin-like squamous epithelium. In many places there were small islands of such nature that the epithelial changes in the air pa~a~es in many instances resembled the growth, of. real ignant tumors. (Emphasis provided) (~) - -18-

SKIN DISEASES INVOLVING HYPERKERATINIZATION The dreadful road to cancer has milestones, warning signs and exit ramps. Sign posts along this road include observable cellulam changes and the precancerous lesions or diseases. The cellular chan~es, hyperplasla and metaplasia with loss of the cilia part of the cell, have been discussed. Much can be learned throughdermatology about the precan- cerous state and vitamin A's influence on this state. Epithelia is present in the skin and so is keratin. But too much keratin, hyperkeratinization, is an early stage in carcinogenesis. The build-up of keratin growths is the disease "keratosis." (See Table A) ,! Keratosis can be "senile, a geriatric problem, "actinic" -- caused by sunlight, or "arsenical" and all are Precancerous. (40,41) Another type of keratosis, seborrheic keratosis, is not precan- cerous. (40) Vitamin A has been shown to prevent and reverse keratosis. 35,43) Howard Behrman, M.D. and Theodore A. Labow, M.D., wrote on page 157 of The Practitioner's Illustrated Dermatology: Senile keratoses (actinic keratoses) are pre- malignant lesions of the skin which, fortunately, usually remain in situ for a long period of time. Susceptible individuals who have had excessive sun exposure over the years have an increased ten- dency to these growths. Senile keratoses are single or multiple well-demarcated f]at, or eley~d~ gray- bland lesions with a dry warty surface. ~"w; -19-
Page 153: 502077008A
Pointing.out that senile or actinic keratosls is precan- cerous, Gordon C. Sauer, M.D., a professor of dermatology at the University of Kansas School of Medicine, warned on page 229 of the Manual of Skin Diseases: Lesion begins as a faint red, slightly scaly patch that enlarges peripherally and deeply over many years. A sudden spurt of growth would indicate a change to a squamous cell carcinoma. Individual lesions may merge and grow into a tiny horn sticking out of the face or neck. (40) On page 230, Sauer warned: To rule out cancer, e~very cutaneous horn should be sent with intact base for histopathologic examination. The incidence of squamous cell carcinomatous change in the base of a cutaneous horn is appreciable. (40) (Emphasis theirs) An etiological factor in carcinogenesis, particularly of the facial skin and llp cancer, is excessive sunlight. First indication of this development is the. build-up of keratin in the exposed area, or "hyperkeratos~s." (45) Hyperkeratlnizatlon alone is not cancer, but pathologists who notice hyperkeratini- zation are advised to take another biopsy. A renewed biopsy taken "sufficiently deep from the border of the lesion" may re- veal cancer cells. (46) Cancer of the larynx, the voice organ which houses the vocal cords, starts with metaplasla, or abnormal cellular change. Then abnormal corniflcation of the epithelial layer takes place. -20-
Page 154: 502077009
Excessive keratin forms on the surface of the epithelium. Kera- tosls then develops in the subepithelial layer. A recent text, Management of the Patient with Cancer,, stated on page 403: When changes of a malignant nature occur in the cells near the basement epithelium, it is re- ferred to as "carcinoma in situ" ... In some cases keratosis may undergo carcinoma if situ changes prior to invasion, while in others the malignant invasion o@~u~s without any observable intermediate stage. (7) Smoking and chewing tobacco is related to cancer of the oral cavity according to cancer experts, Lauren V. Ackerman, M.D., and Juan A. Del Regato, M.D. (49) But here, unlike the tracheo- bronchial tree, in the area of the lips, tongue, mouth, nostrils and gums, the phases in the development of cancer from various causes can be observed. As A~kerman~and Del Eegato pointed out, there are other factors influencing the development of oral cancer -- one is poor nutrition. Women, in the Scandinavian countries par- ticularly, have Suffered from sideropenia, or Plummer-Vinson syndrome, a deficiency in iron and vitamins generally. "The disease is probably due to a dietary deficiency and should be considered a true precancerous condition." (49) A precancerous Condition preceding cancer of the mouth and tongue. (49) -21-

LEUKOPLAKIA AND MOUTH CANCER AND THE ROLE OF VITAMIN A The most common precancerous lesion in man is a disease that involves keratinizatlon of mucous membranes -- leukoplakia. (50) Literally meaning "white patches," this disease is characterized by small, raised, white patches on the tongue, llps, inside the cheeks and on the roof of the mouth when it affects the oral cavitM, and in the Eenito-urinary tract, especially the vulva. . The most common precancerous lesion in man is also a disease that can be prevented and treated with vitamin A. In fact, aside from surgery~ the only positive therapy generally recommended for leukoplakia is vitamin A.

As far as the oral cavity is concerned, ~¥~ess of the mouth is the chief complaint. The resulting leukoplakia is cften a harbinger of carcinoma.(73) The Surgeon General's report Smoking and Health, claimed research data suggested that there is a strong clinical impres- sion llnkin~ the occurrence of leukoplakla in the mouth with the use of tobacco in its various forms. According to the report, oral carcinomas frequently develop at the exact s~te of an earlier leukoplakia lesion. (55) On page 203 the report concluded: Althou~h these results do not warrant any conclusions by themselves, they are consistent with the suggestion that oral cancer is fre- quently preceded by characteristic premalig- nant chan~es and that these have a relationship to the use of tobacco. Apparently excessive smoking rather than merely smoking is a factor in the cause of leukoplakia. And the disease is seen in patients who do not smoke. (56) One of the strongest calls for earlier detection and treatment of this number one precancerous lesion and its more severe mani- festations, leukokeratosls, came from Ashton L. Welsh, M.D. -23-

In Leukoplakia~ Leukokeratosis and Cancer in the Mouth, he said that the continuation of keratinization "progresses until a hardened, horny layer is produced." Unless checMed, this sequence proceeds to malignant dyskeratosis (self-destructive proliferation and changes in the cells). (56) The "field" is then "prepared" for malignant changes by an increase in size of the epithelial layer, as well as an increase in size of each of its component elements. (56)

VITAMIN A AND THE PREVENTIO_N ,,OF CANC.ER ITSELF The most definite findings to date on the antl-cancer effect of vitamin A came from Umberto Saffiotti, M.D., a research patho- logist at Chicago Medical School. Saffiottl, listed as one of the authorities in the Surgeon General's report, was the first researcher to demonstrate satisfactorily that benzo(a)pyrene could cause bron- chogenic carcinoma. He did this by feeding into the tracheas of Syrian Golden hamsters iron particles coated with the carcinogen. After passing through the bronchi, bronchiole and alveolar, the carcinogen was diffused through the parenchyma of the lung where it attacked the bronchi from the "rear" -- from the sides of the cylindrical bronchi away from the inner side protected by cilia. Saffiotti announced his f~st findings showing that vitamin A prevented bronchogenlc carcinoma at the Ninth International Cancer Congress in Tokyo in October, 1966.(57,87) He announced that he duplicated the results of his early experiments when he addressed a meeting, of the Federation of American Societies in experimental biology in April, 1967 in Chicago. (58,59) In his latest experiment, fifty-seven hamsters were given benzo(a)pyrene alone. Fifty-nlne were given benzo(a)pyrene plus 5 mg. (5,000 International Units) of vitamin A palmitate adminis- tered twice weekly in oral doses. Of the 57 annals receiving only the carcinogen, 30 developed 42 squamous tumors in the bronchi and 27 developed 51 papillomas (tiny precancerous growths) of the forestomach. -25-
Page 160: 502077014
Of the 59 animals receiving the carcinogen plus vitamin A, only 13 developed squamous tumors in the bronchi and only 16 developed 25 papillomas of the.forestomach. The number of animals, adminis- tered the carcinogen plus vitamin A, with squamous metaplasia, was 17. Ten exhibited this metaplasia with no tumors. The number of animals who were administered the carcinogen alone was Ii, and every one with squamous metaplasia also had tumors. Saffiotti explained that the vitamin A prevented the squamous metaplasia initiated by the carcinogen from becoming squamous cell carcinoma. His working hypothesls: Vitamin A and a carcinogen aim at a "common target" -- a human process now unknown. The carcinogen initi- ates cancer, while vitamin A prevents cancer. Saffiotti is not alone in investigating a direct connection between vitamin A and the prevention of carcinogenesis. George Wolf, Dr. Phil. of Massachusetts Institute of Technology, an internationally recognized expert on vitamin A metabolism, told a press conference at the December, 1966 meeting of the American Association for the Advancement that his work on vitamin A's role in the production of mucus and the retardation of keratin formation supported Safflotti's findings. (60) The precancerous conditions first became recognized by the dermatologists,(36) and dermatologists are investigating vitamin A's effect on precancerous conditions. Ronald Davies, Ph.D., a biochemist at Temple University's Skin and Cancer Hospital in Philadelphia, in April, 1967, told the American Cancer Society,s Science Writers -26-
Page 161: 502077015
Seminar in Palm Beach and reported in the February, 1967, issue of Cancer Research that vitamin A prevented and actually reversed the formation of papillomas, tiny benigh but potentially precancerous skin tumors. (43) These tumors were first induced on the skin of hairless Rhino mice by applications of the carcinogen 7,12- dimethylbenz(a)antracene (DM~A). According to Davies, vitamin A accelerates the normal process of skin growth thereby encouraging healthy skin. This gives normal, healthy tissue a "competitive advantage" over cancer. (43) Davies~ insisted that vitamin A has this anti-tumor effect even if the subject shows no classical signs of vitamin A deficiency. In 1963, B.K.S. DiJkstra, M.D., a Holland physician, reported that, of 330 patients with bronchogenic carcinoma between 50 and 65 years of age, a curiously high number was born in March and to a lesser extent February -- a time of the year in the era before modern preservation techniques o-- when most pregnant women in Holland were poorly nourished. (62) With no fresh vegetables for them or fresh forage for dairy cows, the vitamin A content of their bodies was low. He stressed the importance of vitamin A in the development of cells such as those in the lining of the bronchi and suggested that vitamin A deficiency is an important factor in the later de- velopment of pulmonary diseases. He reported that more often than not, lung cancer patients have first suffered from other disease of the lung -- caused by poor resistance -- such as pneumonia, tuberculosis or asthma. DiJkstra concluded, "The lack of vitamin A could be an important fa6tor in the development of carcinogenesis." -27-
Page 162: 502077016
One of the earliest references to an anti-cancer function of vitamin A was the work of Errs. FuJumka and Masaki in Japan in 1925. (61) They noticed that rats fed a vitamin A-deflcient diet developed cancer while rats given vitamin A d~d not. The most enthusiastic report on vitamin A's antl-cancer action probably comes from the U.S.S.R. N.N. Petrov of the U.S.S.R. Academy of Medical Sciences' Institute of Oncology wrote in A G~nera~ Guide to Research and its Treatment: Cancer: ...vitamin A deficiency which led in some experiments to hyperplasia and proliferative lesions of the epi- thelium. The addition of vitamin A to the carcinogenic hydrocarbon benzpyr@~e.retarded the induction of malignant growths. (~7) The Council for Tobacco Research-U.S.A. is also interested in the effects of diet on carcinogenesis.

OTttER EXPLANATIONS Not only does a deficiency of vitamin A cause a transforma- tion from mucus-lined epithelia to keratinlzed stratified epithelia, but the deficiency also causes, as part of the process, a disap- pearance in cilia. Cilia are the microscopic halr-like projec- tions of cells lining the lung's air passages. These cilia perform the necessary functions of trapping and moving from the lung- inhaled foreign substances including dirt, irritants and potential carcinogens. Vitamin A can restore the cilia as part of its activity in reversing the keratinization process. (71) How the cilia cleanse is explained on page 267 of Smo_~ and Health:(66) The cleansing mechanism of the mammalian respiratory system is dependent upon the efficient, integrated functioning of a complex system. From the nose to the terminal bronchloles, a mucous layer in which impacted particles and dissolved materials reside is propelled over the surface and removed from the res- piratory tract by the rapid, systemic, and purposeful beat of the cilia. The Surgeon General's report claimed on Pages 267 and 268 that tobacco tars and smoke inhibit this ciliary motility: There seems to be little or no doubt that cigarettes smoke is capable of producing significant functional alterations of ciliary activity in vitro. Such alte- rations could interfere markedly with the self- cleansir~ ~^~o~o~ of ~h~ ~-~O~V tract. The report admitted that the results of the test tube studies with human and animal lung tissue cannot be extrapolated to apply to man, but stated that autopsies have revealed shorter -29-
Page 164: 502077018
cllla and less.clllated cells in smokers than In non-smokers. Vitamin A's effect on the cilia and the cilla's function was explained as early as 1936 by Sir Robert McCarrlson, M.D., Sc.D., considered the father of nutritional sciences, on page ~5 of his book Nutriti.pn a~d H~alth: Let me draw.your attention to the kind of change that is brought about in eplthellumby lack of this vita- min. This membrane is covered by tall epithelial cells, each of which has a fringe of cilia. A func- tion of these cells is to secrete mucus which not only traps bacteria but permits the oilla to perform their movements -- this they can do only when the membrane they fringe is moist and the moisture contains calcium, The function of the cilia is, by their rapld movements in waves, to propel bacteria or foreign particles, as of dust, towards the exterior of the body, whence in normal circumstances, they are ejected. It has been estimated that the cilia move at the rate of about 600 times a minute. Now when the food Is deficient in vitamin A~ the cil a s o o .a _ hE ce Is em- selves l'ose their s~'cretory ~haract~r~" becom~r~horny or kerati~zed~as it is ~alled. ~ure ~p yourselve~ w~at this means~ no longer Is-this tra~plr~, thi~ pro- pelling of harmfu!.partlcies~ whetherof dust or bac- - in the teria~ or both~ possible ~reas sosf~ected. Unless the deficiency be very grave, it is" only at certain places that these chan~es occur. Where they do occur, the local defenses are broken down and bacteria are free to implant themselves in the soil thus made ready for them and to invade the tissues. And it is a curious fact that, in these circumstances, bacteria that may otherwise exist as harmless saprophytes, often take on pathogenic properties and become disease- producing. Mark how serious a view the body takes of these events; at once it sehds u~ ~efe~se forces in ~he fbrm of round ~ells t~ man the b~each~, and these ~ay ~cc~_u~'ate to such an extent ~s actually ad~noid-l~'outgr0wths." (Emphasis provlded~ Cilia then, kept healthy with Vitamin A, can also trap and propel carcinogens. Carcinogens in the concentrations found in our environment, -30-
Page 165: 502077019
are not enough to cause bronchogenic carcinoma. Cell changes from other causes -- and non-functioning cilia in the bronchi -- plus these carcinogens apparently combine, with other factors, to cause lung cancer. (169) One of these other causes of cell chan- ges and an inhibitor of ciliary function is Vitamin A defi- ciency. (28,68) As the W.H.O. report continued on page II: Multiple etiological factors are at work. In this instance the existence of polycyclic aromatic hydro- carbons in both tobacco tars and polluted atmos- pheres, is well established. However, levels are so low that other factors would seem to be required to induce the tumors. From a cursory observation of the pathogenesis It is apparent that the co- existence of squamos metaplasia and exposure tB carcinogen would be likely to increase the locali- zation in such a lung. Again, the paralysis of ciliary action would predispose to this hazard. In terms of cancer prevention it is impossible to rule out the possibility that these non-speclfic links in the chain of pathogenesis may be vital. (69) Mucus -- perhaps overlooked by cancer researchers, is also involved in vitamin A's anti-cancer or anti-neoplastic activity. And certainly, mucus is important in the natural cleansing of the lungs of smokers and non-smokers. (68) The healthy epithelial lining of the respiratory tract is coated with some mucus. How- ever, the epithelia of the vitamin-A deficient subject's respira- ./ tory tract, instead of being covered with a mucous membrane, becomes keratinized. The role of mucus is currently being Investigated by the Council for Tobacco Research -- USA. (63) -31-
Page 166: 502077020
The Report o£ the Advisory Committee to the Surgeon General, Smokln/~ and Health polnts out the need for Investigation lnto mucus and Indications of mucus chan~es caused by tobacco smoke. However, much is known of the relationship between vitamin A and mucus. With particular reference to the findin~ of Saffiqtti,(58) George Wolf, Dr. Phil. of the Massachusetts Institute of Technology, and a recognized expert on vitamin A metabollsm,at the December, 1966, meeting of the American Association for the Advancement of Science said that his findings supported Saffiotti's. Vitamin A stimulates the production of the mucus, while the deficiency stimu- lates the production of keratin and reduces the production of mucus. (60) Mucus, secreted by the mucus producing cells stimulated by vitamin A, may itself have some anti-cancereffect. According to Sm.9~ing and Health, the healthy oral mucosa appears to be resis- tant in general to cancer induction, even when highly active car- cinogens, such as benzo(a)pyrene, are applied. (38) Vitamin A might perform its anti-cancer duties by encouragin~ another "mechanical" function, involving not only the saliva but the cilia as well. As the repo~ stated: Mechanical factors, such as secretion of saliva, interfere with the retention of carcinogenic agents. As mucus acts both mechanically and biochemlcally, so also does saliva. The report continued: ~ Saliva may also play a chemicalrole in modifying the action of carcinogenic agents-on the oral cavity and pharynx. (38) -3z-
Page 167: 502077021
Vitamin A will prevent the dryness that precedes the precancerous mouth lesion, leukoplakia. There is yet another possible explanation for the anti- cancer activity of vitamin A. Researchers at the Dunn Nutritional Laboratory of the University of Cambridge in England reported that two benzene ring compounds, sodium benzoate and bromobenzene "became harmless" when given in conjunction with large doses of vitamin A. (55) On page 61 in the Symposium~ of Nutrition., Thomas A. Moore, Ph.D., one of the world's leading experts on vitamin A, explains : (R)ats given llb~'-doses of vitamin A were able to resist metabolic stresses which proved fatal to animals receivln~ only bare minimum necessary for growth. ~70~ Metabolic processes~ including the Krebs cycle, are being investigated for their relationship to carcinogenesis. (89) Even though the two poisons in the Cambridge study are not the same compounds as the benzene carcinogens similar to benz(a)pyrene, this metabolic "detoxifylng" effect of vitamin A should not be overlooked as a possible explanation for part of vitamin A anti- cancer activity. -33-
Page 168: 502077022
INHALATION OF VITAMIN A Breathing vitamins? Although novel, this concept is neither ridiculous nor unscientific. Since vitamin A acts sys- temically to prevent lung cancer, inhaling the tiny particles of the nutrient puts them in the blood stream quicker than if they were swallowed. The many blood vessels in the tracheobronchlal tree "pick up" the vitamin after the first puff. Vitamin A is then.carried to the bronchi, the site of bronchogenlc carcinoma -- for added local or topical benefit. Swallowing herbs and plants to relieve sickness is as old as the art of medicine itself. But, breathing the smoke from burn- ing stramonium leaves is an ancient folk remedy for asthma that is used even today. "Inhalation therapy," this different way to administer medication, has profound application in treatinE the modern patient. (74,75) Antibiotics are inhaled for both their systemic and local effects against infections. Warmed salt and glycols aerosols are used to treat lung diseases and to diagnose cancer of thelung. Enzymes, chemicals produced by body organs to assist in metabolizing food, have more recently been inhaled by those suf- fering from excess mucus in the lung. "Mucolytic agents," such as the enzymes trypsin and pancreatic dornase have helped patients suffering from bronchiectasls, atelectasls, chronic bronchitis and other bronchopulmonary diseases. Epinephrine (adrenalin), a stimulant, and amyl nitrite, for
Page 169: 502077023
coronaries are Inhaled by patients for their systemic effect. A nitroglycerin tablet, also for the heart, is absorbed into the bloodstream when placed under the tongue. Even the smoker who does not inhale would benefit from Vitamin A in the mainstream of tobacco smoke. The tongue, for- ward parts .of the throat and nasal passaEes contain blood ves- sels capable of "picking up" and transportinE the vitamin through- out the bloodstream. Inhalation of vitamin A provides a conveni- ent and effective way of benefiting fTom the anti-keratinizing and anti-cancer effects of vitamin A. -35-
Page 170: 502077024
HYFERVITAMINOS IS A The intensity of the warnings of vitamin A toxicity is greater than the published data on the subject. Hypervitamin- osls A does occur frequently in children when their mothers give them concentrated vitamin A liquid or vitamin A and D, not accord- ing to instructions -- by dropper -- but in the same large table- spoon dosages by which their mother used to measure cod liver oli (7~) Adult Eskimos and explorers who consumed Polar bear ~ liver, loaded with vitamin A, also became intoxicated by vitamin A.(7~) But according to William H. Stimson, M.D., the medical director and chief of the U.S. Public Health Service Hospital in Seattle, Washington, only six cases of vitamin A intoxication in adults have been reported. (7~) Fifty thousand l.U.'s are considered toxic, but the dosages in the cases of adult intoxication have generally been in the hundred thousands and millions of International Units. (7~) Furthermore, unlike other vitamins, such as vitamin B-I and vitamin D, there are no data indicatlnghumans are allergic or hypersensitive to vitamin A. (75) -36-
Page 171: 502077025
DOSAGE Whenever vitamins and diseases are discussed, questions arise: Does the vitamin have this effect only because the sub- Ject is deficient in the vitamln;, that is, does the vitamin have a physiological effect? Does the vitamin have this effect even if the subject is consuming and utilizing enough of the vitamin; that is, does the vitamin have a pharmacological effect? Cer- tainly the "need" for vitamins was first recognized when their absence from the diet of man and other animals produced certain symptoms. But no one will doubt that some vitamins produce ef- fects in the body not related to fulfilling a nutritional defi- ciency. In fact, ten per cent of all U.S. sales of pharmaceuti- cals in 1963 (87) were sales of vitamins prescribed by physicians -- not sold over the counter. How many of these prescriptions were to fulfill nutritional deficiencies and how many were to treat diseases in patients who were not deficient in the vitamin pres- cribed is not known. -Vitamin A prescribed therapeutically -- and not to supply a nutritional requirement -- for ache, leu- koplakia and hyperkeratinization or k~ratinization diseases in dosages of iO0,000 I.U. 's and up. (90,91) Saffiotti's findings to date have not answered these questions. But Saffiotti did use doses that, while they were not toxic, were substantially larger than doses which would be needed to correct a vitamin A deficiency state in the Syrian Golden hamsters. And Davies reported that vitamin A would even pre.vent and reverse tiny precancerous skin tumors in hairless Rhino mice who were consuming -37-
Page 172: 502077026
adequate amounts of vitamin A. He made it clear to the Science Writers' Seminar, sponsored in April, 1967, by the American Cancer Society, that vitamin A had a pharmacological, as well as a phy- slological effect, in preventin£ and reversln~ papillomas. The distinction between the physiological and the pharmacological ef- fects of vitamins may be merely arbitrary for practical purposes. The minimum daily human requirement of vitamin A, according to the Food and Nutrition Board of the National Academy of Sciences National Research Council, is 5,000 International Units. But more is recommended by such nutrition experts as Henry C. Sherman, Ph.D., D.Sc. and Caroline Sherman Lanford, Ph.D. of Columbia University. On page 290 in their textbook, Essentials of Nutrition, they wrote: In view of the facts mentioned in the preceding para- graphs, the question, how much vitamin A value is re- quired in human nutrition?, logically raises a fur- ther question. Requ~d for what: for the maintenance of passable health that each individual is potentially able to attain? ...Human requirement should, mean not only what is needed for the prevention of specific die- tary symptoms, but further what is needed to permit a human population to realize fully the potentialities of its hereditary birthright. ~78) Because observations upon the human popUlation reveal more frequent slight deficiencies in vitamin A, they wrote on page 292: ...(T)he actual requirements (are) higher than hitherto supposed .... (I)n case of vitamin A there is a wide zone of beneficial increase between the minimal-adequa~e~nd the long run optimal level of intakes. Sherman took issue with the N.R.C. recommendation. in his textbook, Chemistry of Food and Nutrition: On page 468 -38-
Page 173: 502077027
From 6,000 to 12,000 I.U. daily is scientifically more logical to provide' both for individual varia- tions in requirement and for the maintenance o£ such a bodily reserve as has been found to b@ favorable to higher health and longer life. (79) On page 467, he discussed longevity and vitamin A." ...Vitamin A is one of the outstanding nutrients of which stepwise increased intakes induce correspond- ingly higher health and longer life up to intake le- vels about four times that of minimal adequacy. There is no doubt that in these experiments the addi- tion of extra vitamin A to a diet which already con- tained "enough of everything" did positively and constructively build higher health and longer llfe. And we need have no doubt that this same thing may often occur with people....The increase in the average length of normal adult life in these experiments was I0.~ per cent with males and 12.1 per cent with females. If one finds doubt about some questions of relation of vitamin A to disease, one can still be confident that it clearly promotes positive health. The discoverer of another important vitamin, panothenic acid, a B vitamin, Roger ~. Williams, Ph.D., said "There are people (perhaps i0 per cent or less) who have requirements much higher than the general population." For this reason, he recommended vitamin A supplements "at levels higher than ...recommended." (80) Fredrick J. Stare, M.D., Ph.D., professor of nutrition at the Harvard School of Public Health, said, "The diets of teen-age girls are inclined to be low not only in iron, but also in vitamins A and C and the mineral calcium." (81) A World War II survey of dietary habits of industrial plant workers conducted by the Committee on the Nutrition of Industrial Workers of the National Academy of Science's National Research Council revealed that, although "only 15per cent of the workers
Page 174: 502077028
had diets low in vitamin A, nearly every worker had vitamin A lesions (avitaminosis A) in the conJunctiva as shown by the biomicroscope." And so using the "accepted" standards of the National Research Council, symptoms of vitamin A deficiency appeared in many workers who,.according to these standards, were on diets not deficient in vitamin A. (82) Sixteen per cent of American families in 1955, according to the U.S. Department of Agriculture (92) were consuming less than two-thirds of the recommended National Research Council (NRC) Allowances. But American dietary habits have changed and are changing. In the period from 1910 to 1957, the per capita civil- ian vitamin A consumption in the U.S. "before cooking losses" peaked in 1944 to 130 per cent of the vitamin A consumption for the 1909 to 1913 base period. The averages dropped sharply during the period from 19~4 to 1957 (approximately the time this book was written).(83) Cooper and associates in 1958 expanded on the issue of nutri- tional deficiencies in this country in the 13th Edition of Nutrition in Health and Disease: The United States s~ill has mild nutritional deficiencies, especially among people of low income and limited edu- cation. Often these deficiencies are termed subclinical because they are not the frank deficiency diseases found in underdeveloped countries. Surveys made (in the U.S.) during World War II showed that large numbers of people were not eating foods to provide the nutrients recom- mended for optimum health. (83) Although many diets are inadequate "evidence of serious malnutrition may not be conspicuous." "However, poor diet pre- disposes a propDrtion of such groups to the possibility of physical -40-
Page 175: 502077029
ills or defectsresulting from habitual malnutrition. (83) Torben K. With and Umprey Milford of Oxford University in London pointed out a difference between this "minimal requirement" and an "optimal requirement" considerably hi~her. (85) In their book, Absorption, ~et.abolism and Storage qf Vitamin A and Carotene,• they ~explained the way the body absorbs vitamin A after intravenous administration. Intravenous inJec- tlons of vitamin A "showed a distinct rise in the blood sample taken 15 minutes after the injection (from the other arm), but the values reached essentially the initial level with one hour, and the rise subsided completely wlth24 hours." (84) Vitamin A propionate may be the most suitable form of the vitamin. It is available in liquid, water-dispersible form from Vitamins, Inc. of Chicago, lllinols. But vltamin~A acid may be more suitable. Vitamin A, or retlnol, is virtually tasteless, assume the-taste of its base. but does O~ 0 r~

p. o Dr. S. O. Jones Re: Outsider Idea (Ol-ll) U.S. Patent No. 2,770,241 - TOBACCO S~KE FILTER AND METHOd, Joseph Winkler, Queens, N. Y., ~ssi9nor to A~..erican Collo Corporation, New York, N. Y. This patent pertains to the use of polyurethane foam as a cig- arette filter material. %he o~eneral claim in this patent is that polyurethane.being hydrophobic re~noves high molecular weight, water insoluble components from smoke such as polycyclic polyphenols and polycyclic nitrogen compounds. The author states that all of the filters presently on the Inarket are hydrophilic, which r~akes them effective in tl:e re~vai of water-soluble smoke components but in- efficient in the removal of water insoluble smoke components. The c~.ai..m.s include filters made from open cell po3yurethane foam and co||~bination filters consisting of open cell polyurethane foan~ and hydrophilic substances such as cellulosic n~aterials, silica gel ,.etc. In order to evaluate this patent, a sample of P-9100 Polyether Uretha~e Foam was obtained from the General Foam Corporation, 640 Vest 134th Street, ~ew York, N. Yo Cigarettes were prepared in the followin9 manrer: The cellulose acetate filter was removed from regular WINSTON (85-mm.) cigarettes and replaced w~th approximately 95 mg. of P-910O polyether urethane foam. These cigarettes along w~th regular WIRSTONS and WINSTONS with the fi)ter removed were submitted to U~e Analytical Division for analyses. The results of these analyses are as follows: ~.;INSTON Regular t41NSTON Tob. Rod Anal_y_si__s_ v~thout filter WINSTON with Urethane filter Av.

Seve.-'al significant differences were observed in the analytical data from the smoke of unfiltered I~INSTON cigarettes v;hen compared to data obtained from the smoke of cellulose acetate filter and polyether urethane foa,~ filter cigarettes. These differences a~e recorded in the following table.

It would seem that the results of polycycllc

A check with the Analytical Divisinn indicates that they have no ~,ethods for the d~.terminations of any of the polycyclic polyphenols or poly- cyclic nitrogen compounds, and it is believed that the develop~e:.t of these determinations would involve a great length of time and effort. An evaluation oF the analytical data received to date does indicate that although the polyurethane foam when used in quantities so as to produce the same pressure drop as that of a WINSTON cellulose acetate filter is slightly less effective in tar and nicotine removal (9 and 14% respectively), it is considerably more effective in the re- moval of HCN and phenols (24% and 16% respectively). Since this data does indicate that polyether urethane foam compares favorably with cellulose acetate in tar and nicotine removal from smoke, is substantially more effective in th? removal of HCN and phenol~ and the p~l~cyclic aromatic hydrocarbon determinations have not been completed, it is reconlnended that these analyses be repeated For veri- fication and that the decision to show interest in this invention be delayed until these results can be obtained.

Your summary is to be used .or these purposes. Many actions of nicotine on the central nervous system (CNS) have been de- scribed and, as with peripheral nervous mechanisms, both excitatory and i~hibitory responses have been reported. Direct application of nicotine to different brain structures in conscious animals has rarely been employed and confident relation- ships between the action of the drug and specific areas of the CNS have not been fully established. Cholinoceptive neurons have been identified in several sites in the CNS and many effects have been described following injection of cholino- mimetic agents directly into the brain or the ventricles. The terms nicotinic and muscarinic are well understood as applied to peripheral actions of acetKIcholine but their relevance to central cholinergic responses is not clear. The purpose of the present study is to investigate central cholinergic responses to determine the effect of nicotine at the same sites. Both the direct effects of the drugs and the effects on endogenous .acetylcholine will be investigated. Other CNS mediated responses to nicotine will also be studied. ,This research will utilize methods developed in our laboratories. Microapplication of drugs to specific brain areas in conscious unrestrained animals and estimation of brain amines by gas chromatography provide a new approach and should prove {o be powerful tools.

L The two aims of this investigation are (I) to develop and compare animal models for the induction and persistence of goblet cell metaplasia.(chronic bronchitis) using cigarette smoke and other agents particularly viruses and (2) to quantify goblet cell me£~plasia in autopsied'human subjects' bronchial trees and relate it to cigarette smoking.history, dis- tribution of centrilobular emphysema, clinical history of chronic bronchitis, the Reid index and causes of death and degree of exPiratory obstruction to air flow. The animal model which will consist of young and oldVmale rats will be subjected, in groups of 24, to unfiltered cigarette smoke from 20 cigarettes per day in a 1.25 cu ft chamber for 8 hours 5 days a week for thirty exposure days. After this lesion is thoroughly standardized, similar animals will be exposed to influenza or similar respiratory viruses at the end of the smoke exposure period. Because of the resistance of rats to respiratory viruses, hamsters or ferrets may be utilized. The effect of dehydration, starvation, vitamin A deficiency.and estrogens will be evaluated in subsequent series of animals. Perhaps most Importantly the effects of papain lung damage (centrilobular emphysema) on development and persistence of goblet cell metaplasia will be examined. There is evidence to suggest that emphysema predisposes the lung to bronchitis ip human subjects. Sagittal sections of human lungs obtained at autopsy will be studied to q~ .tify the goblet cell metaplasia and relate it to the distribution and severity of centri- lobular emphysema. The lungs will be studied after fixation at l~ cm inflatiop ,sure with normal buffered formalin solution. Both histochemical and ultrastructural stui ~ ill supple- ment the histology. Suitable ~amples will be taken so that Reid indices can be .culated. Particular attention will be paid to signs of airway obliterationand to the relationships between centrilobular emphysema and goblet cell metaplasia inspecific lobules within segments of the upper and lower lobes of each lung.

Your summary is to be used ~r Ihese purposes. Endocytie and exoeytie processes are common to a large portion, if not all, of cells from protozoan to mammalian origin. The end6cytie process which encompasses pinoeytosis and phagoeytosis and the exocytic p~oeess which includes cellular secretion are potential sites for the action of a varlet%, of drugs. The effects of nicotine and other agents will be studied on cultured mouse peritoneal maerophages. For the study of the exoeytie proeess, cells will be clotured in presence of sucrose. This results in the formation of pinoeytie vesicles whieh eon~)ine with lysosomal organelles to give vacuoles containing the sucrose and lysosomal enzymes. The cells with then be exposed to various agents such as nicotine, aeetyleholine, ATP, etc. and the release of sucrose and lysosomal enzymes for~ the cell followed. For study of the endoeytie process, sucrose- laden cells will be exposed to invertase. In the nozvnal situation, invertase is taken into the cell via pinocytosis and the pinocytie vesicles combine with the sucrose containing vacuoles. This eom~ination results in the digestion of the sucrose, the passage of the metabolites through the vacuolar membrane, loss of osmotically obligated ware6 from the vacuole, and a disappearance of the vacuoles. In studying this p~ocess, sucrose- laden cells will be exposed to invertase in the presence of agents such as nicotine and the number of vacuoles in the cell counted as well as the measurement loss of radioactivity which originated from isotopicslly labelled sucrose. The inter relationships of such ions as Ca++, K+, Na+ etc. will also be studied.

The present study is directed toward investigating changes in gastric mucosal blood flow and gastric mucosal cyclic ~IP formation during shJmulation with gastric secretagogues as influenced by nicotine. Conscious dogs provided with gastric fistulas will be used to permit measurement of gastric acid production, gastric clearance of aminopyrine and mucosal biopsies for measurement of tissue adenyl cyclase, phosphodiesterase and 3'5' adenosine monophosphate. Since ulcer formation can occur in the absence of excess acid production but with mucosal ischemia, the finding that nicotine decreases aminopyrine clearance, activity of adenyl cyclase and cyclic AMP formation would provide a mechanism for ulcer formation in men who smoke.

Examples of'such compounds would be acetaldehyde~ hydrogen cyanide, acrolein, proplonaldehyde formaldehyde, acetone and hydrogen sulfide. The amount of each of the substances retained by the respiratory tract would be determined. Such factors as the respiratory rate~ tldal volume and concentration inhaled would be varied to observe their effect. Comparisons would be made o£ slngle breath retention to that retained in experiments of several minutes duration. In .both cases efforts would be made 6o determine the most critical factor co~trolllng uptake. AnQther major aim is to determine the amount tak6n up by different segments of the respiratory tract. Since these substances are brought into contact with the respiratory tract during smoking, it would seem desirable to know as much-as'posslble about total retention as well as fractional retentions by subdivisions of the respiratory tract.

According to recent estlmates.Amerlcans ~moke about500".":-,~;:~:~ ' hi.ion cigarettes, the equivalent of about Z,777 cigarettes a year ~or everF man~ woman, and child in,the countrF or over seven cigare~es ..... :,. .,. per day. The estimate is the result of a stead7 increase up to ~ecent :",..' years. The ~merican Medical ~ssoCiatlon's House of Delegates, con- ce~ned with the health hazards of smoking~ hav~ initiated an education- ~ program on the subject, directed especially to the young. THIS IS DUE TO THE FACT.THAT THE SMOKING HABIT usually begins in the early teens. By the IZth grade in highschool "many children are heavy smokers. Several studies in A~nerican secondary schools indicate that about one of every four .boys smokes cigarettes, and one of every eight girls. The boys also are heavier smokers. This ratio follows through in adult life. Exact figures fluctuate, but it has been estimated that about 60 per cent of ~erican men smoke as contrasted with 30 per cent of American women. SINCE 1939, NUMEROUS SCIENTIFIC STUDIES have been con- ducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and has permitted sound evalua- tlon of the health risk. Based on evidence derived from human popula- tion studies, clinical and autopsy studies, and animal exPerimenta. tion, the smoking of cigarettes does constitute a definite hazard to health.
Page 218: 502077148
SKILLED RESEARCH PERSONNEL HAVE CONDUCTED studies that prove tobacco smoking, particularly c.l~arette smoking, is associ- ated with a shortened life expectanc7. Cigaretts smoking is regarded as an important factor in the develop~nent of cancer of the lun~ and cancer of the larynx, and is believed to be related to cancer of the bladder, esophafius, and oral cavity, l~lale cigarette smokers are said to have a higher death rate from coronary heart disease than non- .smoking males. Cigarette smoking is regarded as the most important of the causes of chronic bronchitis'in the United States. A relationship does exist between pulmonar~ emphysema and cigarette smoking, but it is not established that this relationship is causal. The majority of. .physicians and researchers believe these observations to be correct and say, "Don't smoke! If you don't, smoke, don't start." AN INDIVIDUAL I~L£Y. TRY TO~ REACH A SOLUTION about his own smoking by studying the evidence, making a rational decision, and acting on it. Accordingly, let~ us review some of the evidence that has accumulated Irorn the i, esearch of many ..investigators .during the last~wo decades, • SINCE SMOKING HASMARKED PHYSIOLOGICAL EFFECTS~•~" perhaps we should ask what is smoke? . ... " Smok~, a "productof combustion~ ~Is a mixture of gases, various vaporized chemicals, and millions.of minute particles of ash and other solids. These are drawn into the mouth ~during smoking and into the lungs by inhalation. The smoke includes some vaporized nicotine, a- toxic subs'~ance found in tobacco, although much of it is changed by heat. It contains tars and other..products from the partial burning and distillation of the tobacco. A SMOKER GETS MORE NICOTINE and tar if'he smokes a cigarette to the end. A significant amount of carbon monoxide is also produced. It is picked up by the red ,corpuscles of the blood, which • normally carry oxygen. The more heavily they are loaded with carbon monoxide, the less is their oxygen-carrying capacity. SMOKING CAN AFFECT THE RESPIRATORY SYSTEM. As smoke is drawn into the breathing passages and the air sacs of the lungs, the gases and particles in the smoke settle onto the surround- ing membranes. One point of special impact is ~vherever a large air- way branches into t~vo smaller ones. This sort of location is where most lung cancers begin. PATHOLOGISTS AND PHYSICIANS SKILLED IN THE MICROS- COPIC anatomy of disease--consistentl7 find that the lining mem- branes become damaged and are less effective .in removing the toxic and irritating chemicals introduced by the inhalation of smoke.
Page 219: 502077149
PATHOLOOISTS ALSO HAVE FOUND THAT SI~OKII~G" not ordy thickens the lining membranes of the air passages and obstructs them with secretions but also stimulates a contraction of the muscles in the'air passage walls which narrows them and further reduces air flow. There is considerable evidence that a single cigarette will mark- edly reduce the air flow of even an experienced smoker. Potentially harmful particles are deposited into the air sacs, the point where emphysema develops. Recent pathological studies in humans suggest an association of these changes found in smokers and development of this disabling lung disease. SMOKE ALSO AFFECTS THE MEMBRANES llning the larynx or voice box. A pathologist identifies a smoker's larynx by the thicker, often swollen vocal cords~ The changes in the voice box are similar to those that occur in the air passages and in the lungs. These irrita- tions cause swelling, and increased secretion and result in "smoker's cough,' ' SMOKING AFFECTS THE CIRCULATORY SYSTEIVI--the heart and blood vessels. Nicotine, if injected or taken In tobacco smoke,., stimulates that part of the nervous system that controls the heart, blood vessels~ and other internal organs th.at function almost auto- -~... rnatically. 1~Iore s'mokers die from coronary heart disease than do nons rook ers. AMONG OTHER. EFFECTS OF SMOKING are those of an ap- .:" parent tobacco a11ergy in some senitive'persons, and aggravation of .... peptic ulcors. Patients with these conditions are genera11y advised not to smoke. SMOKING IS DIR.ECTLY ASSOCIATED WITH ACCIDENTAL • DEATHS from fires in the home. A study of death certificates by the " National Safety Council led to an estimate of 1,000 deaths EACH YEAR in fires caused by smoking. About 900 of these deaths occurred in the home; many of them when people smoked in bed. l~ore than an average ... of two fatal conflagrations per da7~ wholly preventable! " .. WHILE ALL TOBACCO SMOKING is ~belleved to affect.health and life expectancy, cigarette smoking appears to have a much greater effect than cigar or pipe smoking. Among the possibl.e explanations are that cigar and pipe smokers often do not inhale, and the tempera- ture at which the tobacco burns is different. • FILTERS AND DENICOTINIZATION OF TOBACCO or ciga- rettes are alleged to reduce the hazards. However, denicotinization has no eHect on the kind or amount of tar in the smoke, and filters can only reduce, not eliminate, the hazards. THA~ SMOKING IS RELATED TO PSYCHOLOGICAL AND SO- CIAL SITUATIONS is well known, not only 'in the reasons people give
Page 220: 502077150
for smoking, but also in o~her~ obvious reasons which the' don*t give; Young people, often start smoking in imitation of older people who smoke or as an expression of a subconscious wish to be like them. O.Ider children and youth want to be accepted by their friends and associates. Often friends dress alike, talk alikeB and have other be- havior in Common. Smoking may be part of this attempt to conform. • Not smoking could also be part of a group p.attern, . AS A MEANS OF RELAXATION, the mechanical aspects of. smoking are recognized. Under tension or during an awkward Iu11 in activity, smokers probably do relax by taking out a package of cigarettes, choosing one, getting matches, lighting the cigaretteB and handling it. SOME AUTHORITIES SUGGEST THAT A CIGARETTE repre- " sents a reward that a smoker can offer himself whenever he wishes, or ~that the act of smoking represents a means of self-expression. In young people, it may represent freedom to do as one pleases, or be a reaction against adult authority. Others believe that pet)ple smoke "because of the need for oral activity to fulfill an unsatisfied suckling RECENT STUDIES HAVE SHOWN ~THAT YOUNGSTERS whose parents smoke will also tend to smoke. If older brothers and sisters smoke, the younger ones are more likely to become smokers. •l~luch research remains to be do~e before an understanding is reached regarding the factors in smoking that produce satisfaction and often lead to habituation. WHAT DO AUTHORITIES SAY ABOUT SMOKING? Physicians, s~ientists, and many other health agencies have studied the relation- ship of smoking to health and most are in general.accord. The most extensive examination of smoking was published inl January, 1964, by the Advisory Committee to the Surgeon General of the U.S. Public Health Service. The committee reported: "Cigarette smoking is causally related to lung cancer in men; the magnitude of the effect of cigarette smdking far outweighs all other factors. The data for women, though less extensive, point in the same direction," THE DANGERS IN SMOKING~ ESPECIALLY HEAVY SMOK- ING OF CIGARETTES, are recognized all over the world. Statements on the subject have been issued not only by the U.S. Public Health Set- • vice, but also by the Royal College of Physicians in Great Britain and a special committee of the World Health Organization. THE AMERICAN MEDICAL ASSOCIATION STATED officially at. its Annual Convention in 1704: "The American Medical Association • is on record and does recognize a significant relationship between cigarette smoking .and the incidence of lung cancer and certain other diseases, and that cigarette smoking is a serious health hazard."
Page 221: 502077151
THE HOUSE OF DELEGATES OF THE AMERICAN MEDICAL ASSOCIATION has. officially endorsed the actions of the Joint Coral rnittee on Health Problems in Education of the National Education Associa.tion and the American Medical Association. This Committee, recognizing that "...the specific components oftobacco exerting harm- ful effects on the human organism have not yet been defined and the exact pathological and physiological actions of these components have not been determined, nor the psychology of smoking full7 understood, recommended authoritative~ research...in smoking such as that being conducted by the AlvtA and others." THE JOINT COMMITTEE ALSO RESOLVED "That schools, physicians, health departments and other community agencies operate in an aggressive program designed to discourage children from starting, the smoking habit and to influence youth who are smok- ing to discontinue the habit." THE AMERICAN IMEDICAL ASSOCIATION has not confined itself to mere endorsement. It has never allowed tobacco advertising in its health magazine, TODAY'S HEALTH, since its establishment in 1925, and it banned tobacco advertising from its Journal for physicians and its exhibits at scientific meetings in 1954, long before the statis- tics had accumulated to their present overwhelming mass and rendered the hazards of 'smoking so apparent. It is sponsoring clinical and sci- entific research, as well as an educational program on a continuing basis to call to the attention of the public, particularly young people, the known evidence against smoking. WHAT CAN BE DONE ABOUT SMOKING? Manufacturers are trying to reduce the hazards of smoking by modifying tobacco, reduc- ing nicotine content, and filtering the tars. The long-range eHects of these efforts are not now know/,_ and cannot, in the_ nature of things, become known for some years to come. Cancer often waits Z0 years 6r more to become manifest after the irritation that provoked it, and by the same token, years must pass before the effectiveness of a pro- gram of prevention can be demonstrated. RESEARCH HAS BEEN INITIATED TO FIND AND ISOLATE or refine l~armful substances so that those who smol~e may continue to smoke safel7. Thus far, the results have been discouraging. As part of its concern with this problem, the American Aiedical Association is sponsoring a large-scale'study to determine mechanisms by, which human ailrnents may be caused or aggravated by smoking, in order to • define more accurately the role of tobacco in health and disease. WHILE TO SMOKE OR NOT TO SMOKE is a matter of individ- ual choice, most authorities now agree that never to smoke is prefer- able. Further, they would agree that significant evidence is accumu- lating which, indicates the desirability for the heavy smoker to stop smoking or cut down to the point of moderation.

Leonard Zahn ~nd Assoclates~ :Inc. ~ubJect.. American l~ical Associat~ton ~Meeting, July 13-17, 1969 I, House of Delegates -- Activities on ~moPAng, A. The three anti-smoking resolutions (copies of which were obtained early • ~nday, July 13) were referred to the House*s Reference Committee 0, which held hearings on these and other proposals beginning Monday morning~ July i~. The resolutions had been introduced by delegations from Arizona, Oregon and Wis- consin. Committee chairman Clarence S. Livlngood commented: "This is an old subject.= Delegate Daniel Te Cloud of Phoenix said his state's resolution ha~ been introduced at the request of the Arizona Hedlcal Association. "Though the AMA has taken action against smoking through statements and resolutions# we Would llke to see more of an anti-~oking effort in regard to television and advertis- ing and especially in the high schools. We want to see a good education program.z" Delegate Ernest T. Livingstone of Portland, supporting the Arizona and Wis- ¢onsin resolutions, said the Oregon proposal was offered to change the situation ~here the HEN Department was campaigning against smoking while the Department of Agriculture "doe s the opposite." He gave the committee copies of what he said was correspondence with Oregon's Congressional delegation. The comnittee's report, to the House of Delegates was made Tuesday m~i~ting, July 15, and was adopted after two changes in the section referring to the anti- smoking resolutions. . Delegate John" C. Quertemous of Kentucky proposed that the three underlined words in the follo~ng paragraph be changed to "the incongruity of"." Resolved~ that~ through appropriate channels# the American Medical Association indicate to the Congress of the United ttate~ its oppositiou~ ~ the expenditure of tax dollars to promote the production and sale of tobacco while at the same time spending other tax dollars to discourage cigarette smoking because of its hazard to health." California delegate Alfred J. Murrieta, referring to 196~, questioned ~is sentence: "In the same year the House of Delegates 'commended the establishment of the research program (on snoklng and health) that is being carried out by the American Medical Association Education and Research Foundation." Dr. M41ford Rouse said the AMA-ERF does not do any tobacco-health research but is only a "conduit" through which funds are channeled, to scientists. The sentence was deleted. B. The AMA-ERF Liaison Committee to tho 'House of Delegates reported that tobacco end health research, funded by the tobacco industry, "is necessary and of value" though public relations of a "positive nature have not been derived by either the AMA or the .AMA-ERF by the latter~s association with the tobacco industry."
Page 231: 502077173
Leonard Zahn and Associates, Inc. The Liaison Committee recommended every physician and the public at large be informed by the AMA of the relationship of AMA-ERF to the tobacco research project and that the program be continued. Reference Committee E of the House of Delegates concurred in its report ~nd the delegates adopted the report without discussion. Anti-Smoking Papers. Three papers dealing directly with smoking were on the program~ A. "Termination of smoking by a single treatment" -- Herbert Spiegel, a psychiatrist at Columbia University College of Physicians ~nd ~urgeons. As predicted, this paper attracted considerable press attention. Jim Spauldiug, science editor of the Milwaukee Journal, commented~ "It was cute and easy to write." Further, a press conference for Spiegel was held Monday morning, July 15, a day in ~hich the House of Delegat.es was" not in session. A copy of his paper was obtained. Splegel's one-shot, self-hypnosis session for smokers is based on whnt he called the "positive" approach: s~oking is a poison for your body# you need your body to llve~ you owe your body this respect and protection. B. ~k~at about smoking?" --Daniel Horn, USPHS. A copy of his paper also was obtained. Horn's presentationwas pretty~uch a rehash.of what he has been saying for a longwhile. He said that since the turn of the century, the effects of smoking have wiped out all beneficial results related to increased life ex- pectancy. Life expectancy for males has increased only fouryears, not the expected eight years. Cigarette smoking is declining in this country "on an absolute basis. The reduction of smoking is increasing." Horn personally delivered copies of his paper to the scientific press room at the Coliseum. He appeared to be trying to promote a press conference for him- self. The "sameness" of Hornts paper was pointed out to the man in charge of the press room and he agreed a press conference would not be of any value to the writers present. C. "Cigarette smoking and the serum activity of enzymes associated with atherosclerosls" -- CTR grantee Alfred Kershbaum et al. Delivery of this paper was cancelled because of Kershbaum's recent unexpected death. 0 0

Leonard Zahn and Associates, Inc. 3. Other Papers. "The ~nterdisciplinary approach to the rehabilitation of the emphysenmtous patient" ~- Dr. Irving Kass, University of Nebraska, Omaha. Kass noted that three factors are responsible for the increased incidence of chronic obstructive lung disease in the U.S.: smoking, air pollution, and ~overty. All patients at his universitytsRegional Chest Center are encouraged to stop smoking. However, he added, behavioral scientists at the center have found that some. patients ~to have smoked for many years cannot function adequately ~hen cigarettes are prohibited. Dr. Yredrick J. Stare, a CTR'grar, tee, spke on "Calories, cholesterol and alcohol." He noted that "smoking, lethargy, high blood pressure, obesity, and a host of genetic factors are all involved in heart disease along with cholesterol." Several physicians, speaking at a session on "Chronic Pulmonary Insufficiency and Problems of Air Pollution," appeared at a press conference. Dr. fan Higgins, University of PAchlgan, Ann Arbor, noted that cigarette s~oking "is almost certain~v a more important cause of chronic respiratory disease, lung cancer and heart disease than is air pollution." (His actual paper was on e~fects of sulfur oxides and particulates.) Dr. John R, Goldsmith, California Public Health Department, Berkeley, said that cigarette smoking is a major contributor to chronic respiratory in- sufficiency. Ozone can interfere with pulmonary function and nitrogen dioxide, in long-term experiments with anima~ls, has produced a condition resembling emphysema. (His paper was on the health implications of automobile pollution, with emphasis on lead anti-knock compounds in gasoline.) John A. Zapp, Ph.D., ~ilmington, Vel. (he is associated with a research instituted funded by du Pont). Zapp said that from a scientific point of view, the evidence about air pollution and health "is not yet firm." There could be a problem in the future, if the present composition of pollution continues and increases in intensity. Heavier levels of air pollution impose stresses on people and "if they're not in good health~ the results could be disastrous." Dr. Stephen Ayres, St. Vincent's Hospital, New York, noted that manydoctors are unaware of the air pollution-disease relationship. Respiratory infections can result from air pollutants or "inhaled particles such as cigarette smoke."

D., Cha:.rman Mr. Spea/:er and Members of the House of Delegates: Reference Committee E gave careful consideration to the several items referred to it and submits the following report. (i) REPORT E OF THE BOARD OF TRUSTEES - N~.; USES OF OLD DRUGS Report E of the Board of Trustees informs the House of Delegates of the action taken as directed ~j Resolution 14 (C-68). The ~.~% was directed to discuss with the Federal Food and I~'ug Administration the legal implications of physician use of drugs for purposes not approved by the FDA for inclusion in official labeling, such as package inserts. Your Reference Committee is pleased to note that a meeting has been held ~ith the FDA Geneyal Counsel and a member of the FDA Bureau of ~.~dicine. A report on the statements made by the FDA representatives ~s published in the February 17, 1969 issue of J~ and pertinent ex- cerpts are appended to Report E. The report of the discussion should answer many of the questions that prompted introduction of Resolution Soeaker, your Reference Co~_mittee recom:.mnds accewtance of the House of Delegates. ~'~ (2) Rr~ORT BB OF THE BOARD OF TRUSTEES - BLOOD DONERS Report BB of the Board of Trustees calls to the attention of the House the need foy mo~e volunteer blood donors and requests the con- currence of the House in three recommendations submitted by the Committee on Blood to encourage volunteer donations. The United States Post Office would be urged to give favorable consideration to the issuance of a commemorative stamp calling attention to the need for more volunteer blood donors; designation by Congress of Jsnuary, 1970 as National Blood Donor [bnth ~muld be encouraged; state medical assoclatious would be encouraged to promote actively state legislation to permit persons 18 years of aze or older to donate blood without parental per- mission or authorization. J,Ir. Speaker, your Reference Committee recommends adoption of BeDort BB of the ~oard of Trustees ~v the House of Delegates.

The first repo:'t of ~ ~ ~n~; ~/.~V~-E~iF Liaison Cor~dttee of the House on its study of these proz~'~us deserves the carefal attention of all the Delegates. Your Reference Committee recommends that these reports be accented bl,: the House. The Supp!euentary Report of the A],~A-ERF Liaison Committee contains five recom~,~endations for House action based upon the careful conslde~-atlon and study the Committee has given to the purposes and programs of the Foundation. Your Reference Co~tmittee concurs in these reco~:~endations ~Ith the addition of one change requested by the Liaison Committee. On page l, line ~2, the Liaison Cor.~ittee has requested that the phrase, "because of fiscal considerations," be inserted followinc the phrase, "at the present time". ~.[nen the /U~'~%-ERF Student Loan Procram ~as discussed by witnesses appearing before the Reference Co~a~ittee, information was presented in- dicatinG that a number of medical students may face serious financial problems if mo~-e funds cannot be made available at lo~: interest rates through student loan programs. Further, financial assistauce needs to be made available if prospective students unable to afford the expense of a medical education are to be recruited. Your Reference Committee was informed that the A2.5',-ERF Board of Dissectors has appointed a special committee as recommended by the A/~Dk-ERF Liaison Committee me study these problems and recozt~.end solutions to alleviate the crisis faced by financially distressed medical students. Your Reference Committee concurs in the Liaison Committee's emphasis on the importance of info~ing the profession a~ the public of the role the ~,~-L"~F serves in co:~junctlon ~ith the Tobacco Research Project. The A/~-ERF Liaison Co~nittee has pointed out that the Foundation serves only as a conduit for funds contributed to support basic research on the re- lationship of tobacco to health. The Foundation, through the Comzaittee for Research on Tobacco and Health, has established a project-review committee for the grantinz of funds fez institutionally-sponsored, basic research and conducts none of this research activity itself. Your Reference Committee feels that this activity of the ~.~-ERF is comple- menta~ to the objectives of the Association "to promote the science and art of nedlcine and the betterment of public health". ~. Speaker, your Reference Committee reco~.ends adoption of the Supplementary Reoort of the PJ~Sk-ERF Liaison Com~ittee of th4 House ~ith the requested chan~e..oq3~_a~xe_~__li_ne___~ REPORT A OF THE JUDICIAL COUNCIL - REVI~'~ OF ETHICAL CONSIDE~&TIO~ REL~ING TO CL~;ICAL LABOPJ~TORIES Report A of the Judicial Council, containir4z a review of policy positions adopted by the House of Delegates, prior opinions of the Judicial Council and a comprehensive analysis of current issues relating to the delivery of laboratory services, provides a valuable source docu- ment for the House of Delegates.

C Report of Reference C~mittee G Presented by: Clarence S. LivJ.ngood~ M. D., Chai~.nnan ~ p-~ 1 Mr. Speaker and ~bers of the House of Delegates: 3 6 8 9 13 lh 16 1B 1.9 ~3 31 33 35 3? 39 (1) REPORT I OF THE BOARD OF TRUSTEES - SCHOOL AND COLLEGE PHYSICAL EDUCATION Report I of the Board of Trustees would reaffirm a resolution on physical education programs in schools and colleges which was adopted by the House of Delegates in 1960. This resolution urges medical societies to do everything possible to encourage effective physlcal education for all students in schools and colleges. By effective physical education is meant regular instructional periods involving a wide varietyof physical activities designed to catch ~e interest and meet the needs of all pupils -- the under- developeS, the physically average~ and the physically gifted. In 1960 when this resolution was adopted, the American Medical Associa- tion did not have a C~aittee on Exercise and Physical Fitness as it now does. Accordingly, this Co~uittee believes that reaffirmation now~ ~en the interest in physical fitness is accelerating, would strengthen the Committee's posi- tion in trying to implement one of its major objectives -- to improvethe physical fitness of our youth. The Committee, through meetings and conferences, has close working relationships with other agencies interested in physical fitness and believes that~ through its own channels and those of these other agencies~ more could be done to implement the intent of this resolution than was possible upon its original adoption. The Boar~ of Trustees agrees with the Con~ittee on Exercise and Physical Fitness, that reaffi~aation at this Convention would have a fine potential for implementing the Committee's objectives with respect to the physical fitness of youth. _Mr. Speaker, your Reference Committee reco~ends adoption of Report I oft he Board of Trustees.

In te~s of this bachgroun~ Resolutions !~, BS, ~, ~nd 75 were considered together. In 1967, the House of Delegates of the American Medical Association reaffirmed its support "of all forms of nursing education including bacca- laureate, diploma, associate and practical nurse education puogr~ms;" and commended "hospitals that conduct diploma schools of nursing for the great contribution belngmade by these schools to the health needs of the nation." In 1968, the House urged increased subsidies to hospital nursing. schools, encouraged state and local medical societies to seek local "sources of financial support for hospital nursing schools" and urged concerted action by/~4A and other appropriate agencies "to encourage increased enrollment in hospital nursing schools". Your Reference Committee believ~ that the testimony given at the Reference Committee hearings ~as directed toward the same objectivesthat the House action of 1968 sought to achieve. It was also indicated that the obher resolutions on this subject have similar ~oals. Accordingly, your Reference Committee recommends reaffirmation and s~ren~thenlng of AMA's ~osi~icn in this area throu~ a substitute resolution as fol~ows~ i~ lieu of Resolutions !~,.. Resolve~, That the American Medical Association reaffirms its support of all forms of nursin~ education includlnc bacca- laureate, diploma, associate, and practical nurse education programs, and be it further Besolved, ~nat the American Medical Assoc~atlon encourage the continuation of federal subsidies to schools of nursin~ education, and be it further ~esolve~, That the American Medical Assoclaticn talm appro- priate action in consultation ~ith the professional and vocational nurses' associations, American Hospital Associa- tion and other concerne~ groups to increase the enrollment in diploma sohools and practical nurse education programs, and be it further Resolve~, That appropriate steps be taken by the American Medical Association to encourage recruitment into the health professions, cf health-oriented personnel released from the armed services, that the cooperation of allied health professions and vocations be soug~,t in this effort, and that such action be referreS to the Board of Trustees and its Council on Health Manpower for implementation.

This culminated with the adoption of Resolution 13 (C-68) on smoking and health at'the Clinical Convention in Miami in 1968. Your Reference Committee believes that Resolution 13 reflects both the intent of the current Resolutionslh~ 39, and 7~, and the testimony presented on the subject at this Convention. Accordingly your Reference Comr.ittee recommends that ~is position as set forth in Resolution 1~~ be reaffirmed ~ith one a~ditional resolve in lieu of Resolutions 14, ~9, and 72, as foll~,s: ~8 ~9 30 3~ 3~ 33 3~ 35 36 37 39 Resolved, That the American Medical Assooiation again urge Itsmem~ers to play a major role against cigarette smokiu~ by personal example and by advice regarding the health hazards of smoking; and be it further' Resolved, That the American Medical Association discourage ~moking by means of publi~ pronouncements and educational programs; and be it further Resolved, That the American Medical Association take a stFon~ ~tand against amoking by every means at its command; and be it further Resolved, That, through appropriate channels, the American ~2 Eedlcal Association indicate to the Congress of the United es ~tg'o~p~~ the e'.~enditure of taX dollars ~o 4~ /promot~e the p~oduction and sale of tobacco while at the same ~5 / time spending other tax dollars to discourage cigarette smok- ~6 ~ Ing because of its hazard to health. ~ /" Mr. Speaker, Your_Reference Committee r~commends th, _adopti~ Pf hgi ~esolut~pn_!~ as amend~. . _. ~ .... ~ ' • -# 0

Preparations of cat papillary musc~ and dog atrial trabeculae will 5e obtained from normal hearts and from hearts in failure Induced by chronic pulmon~.ry artery con- striction. Portious of normal and ~iseased human myocard[um will be obtained from hmnzns undergoing open heart surgery. Several concentrations of nicotine will be added to ~e perfusate for both normal a~d fai]ed ~nimal and human myocardial preparztions. ~e length-tensiqn and force-velocity relations for these preparations will be obtained to determine if nicotine differentially affects force development by normal and failed myocar~um. ~e 1shah-tension relation and diastolic compliance wiD be examined in similarly perfused preparations during controlled s~quentizl changes in len~h; these len~h change~ will include excessive ~mounts of stretch so that optimal len~h can be deterr.~ined. These da~ will permit a comp~risou of the ~ffects of nicotine on diastolic compliance ~nd optimal !ength for normal ,~uscles ~nd may indicate if nicotine influences c~rdiac output by altering the pressure- volume relationship for the intact heart by ~ctious ~ddit~onal or separzte from its positive inotropic action, " The ~ctions of nicotine will be determined on ~ftercontr~ctions induced by cardiac ~lycosides, czlcium, low temperature and cstecholzmines normal ~nd failed muscles. Simultaneous monitorin~ of electrical and mechanical activity will a!low an analysis of whether nicotine ~cts on transmembrane potentials or mechanical "threshold' potentials.

Introduction The Etiology area is char~ed with responsibility for the major share of the lnstitute's programmed research on cancer causation and preventions includin~ the major portion of the Special Virus Leukemia program. Its investigations extend fred the studies of cancer induction in defined human and animal populations to studies under laboratory conditions of the ftmdamental aspects of the mechanisms by which viral and chemical agents produce cancers by alterln~ the ~etabolism in living systems. Scientists are responsible not only for their individual research, but also for provision of stron~ central leadership in the concep- tualization, design, and implementation of an im~Inatlve and integrated attack upon these problems, in collaboration with other investigators in this countr~ and ebroad. Central to the Etiology area's approach is the concept of an interaction of multiple causative factors contributed by man as a host and by his environ- mant. The Demography prorrams (further described under "Biometry, epidemiology and field studies") in addition to providin~ a continuous monltorinX of cancer incidence, prevalence, end mortality rates end trends, are desil~ned to analyze defined populations having tmusual risks to specific cancers or known exposure to hi£h risk envlronnents, to reveal statistically silmificant cause-and-effect associations and dissociations leading to the discovery of etiologic factors and agents. The experimentally oriented xmits of the Etiolopy area select end combine, under carefully controlled conditions, those host and environ- mental factors which appear to be si~mificant in cancer etiology. From this point, the)' proceed to verify or deny such si~nlficance by success or failure in producing cancer in animals. It may then be seen that the synthetic approach on one hand and the analytic approachon the other ~re purposely united in the ~tiology area to complement one another.

It will ta_ke time, because the devices are re-. quired only on the 1968 c_ars and thereafter. Secondly, we have had abatement actlons--nine abatement actions---which have led td chan~es in pract_ices o~_ fuels or the use of fuels in majorcities, which is going to cut down the amount of sulfur oxides in the a~r.

There was a directive in the Cle.~n A~r Act of 1967 to increase our r,e~_earch particularly along the line of removal of sulfur from fuels.

We have not identified the item in ¢~g,,trette smoke or in the gaseous phase. Iwould like also to poin: out that we are be~nning to thi~k that there may be some potentiation of .items in the cizarette smoke and items in the environment which lead to it rather than being a single ~tem.

That leads me on to this question. Last year I inquired if there were any spec;.fic agents in cigarette smoke which could be pointed .to as the cause of lung cancer and you ~tid there ~'as not. Pre3mnablyyou have spent, a ~'eat deal of money over the pagt year in pursuit o,f,,~his elusive--if existent~agent and I ask you, Can you report that ~ ou ha~,:e finally: loc~a texl such an agent ? . -. Dr. SZ~W,tRT. ~No~ butI t.lfink that the question is not quite what the answer was. I think we have many agents in cigarette smoke which are hi_~hly~, _ p_.robable as._ heine,. ~,.the. etiological_ agent~_ of hm~_ cancer. . But ~ cannc;t ~y this specific ~tem Is ~t. " • , " Mr. Hw~. The 1964 Surgeon General's report on smoking stated, at page 3~, that nicotine was not an important health hazard a~d, at page 75, stated that nicotine probably does nol~ represent a significant health m'oblem. Last year when you were asked about this to deter- mine w~ether there hhd been an~ change in scientific thought about nicotine, you indicated that there was a re,dew beh~g conducted by the PHS of the current resehrch and that the review would be issue~l when it was completed, l~Ias the review been completed and can you now tell us if you can give us some concrete information along ~his Dr. Svzw,urr. Yes. The review is the report that was sent to the CongTess as required by law last year, which_brings up to date tl.e scientific evidence that has developed since the 1964 review. There is one interesting study reported in there which lends one to hare creases the oxygen demand of heart muscle. This is a very interesting
Page 269: 502077240
findings it this is so, because it could possibly link nicotine to cardio- vascular diseases. Again, I say this is just an addition. We also know that some of the _properties that cause physiolo~cal dependence on cigarettes are in the nicotine area. There has also been some research done on the enzymes which handle the nicotine in the body~ and the ability to characterize smokers and nonsmokers as havin~ different enzymes. There has been some prooress made on mcot~ne s~nce the 1964 report• I think the conclusion of the 1964 report was correct with the evidence that was available. But I think we need to pursue it a lot further in the scientific realm before we could draw any other conclusion than what was in the 1964 report. - .... ~Ix. Huz,~,. In other words, we will spend probably sereml million in an effort to establish nicotine as a he~lth ]~azard notwiths~u~ding the 1964 report? . ' :. • - . Dr. STmW, ZT. I think what we are doing is we are spending ~veral mglions to find what it is that makes cigarettes hazardous to health. In exploring, this we will be looking at the hydrocarbons, the _ea~es, the tars, and the mcotme. We am looking at a]l avenues.

Don't you really believe, Doctor, that there is ~ substan- tial number of people in the American Cancer Society and conceiv- ably in your own Public Health Service who would love to see a Vol- stead Ac.t for tobacco or, failing to achieve that, at least a social climate or emotional climate created which would approve cigarette prohibi. tion~ Is that what you are getting to ~ .... Dr. Szzw~z. I cannot speak for the Cancer. SOciety, but as far as I am awara of, nobody in the PHS is talking that way. ' "" L~ICO OANOER TASK FORCE Mr. Hb'z~. Isn't it true that when you formed your lung cancer task force the people who favored prohibition strongly recommended that educational methods aimed at preparing the mental climate in this ~ountry_ for cigarette prohibition be supported in advance~ Dr. Srzw,~z. The hn_~ cancer te, sk force has come up with a pro- gram of three avenues to%'ard the problem of lung cancer. One is to motmt a research program on etiology of cancer, lung cancer. Thi_s would be a level where it would cover occupational exposures and other exposure~ to lung cancer. The second avenue is to improve the diagnosis and treatment and the.third is to pursue a less hazardous cigarette. We have now formed work groups around the three avenues and the work group on the less hazardous cigarette is meeting on March 11. Mr. HVL~. In connection with the emotional climate you and your associates are trying lo produce in this co~mtry_, I woul~l lik_'e to turn to the subject of several pamphlets which the Public Health Service has sponsored recently.

No !~ I do not think it was trying to do that at all. It was saying that if ~ou are a cigarette smoker t]~ese are your health characterlst~cs. If you are not a cigarette smoker these are your h~ealth characteristics.

73 Mr H~L. Now. Dr. Stewart, with resp~_ ot .to the study conducted by th~ National C~nter for Health Statistics--and which states very p~_ainly the statistical associations do not establish a causal relation- ship-t-_I'd like to ask you the following questions: 1. Is it not a fact t'hat 60 percent o] t'he information .a.bout men who had ever smoked was obtained from other people~ Isn't that a quaint way of obtaining infor..mation ~ Dr. Srew,~T. I dont see the relationship, 60 percent of the infor- mation about men. Mr. HVL~,. Pardon~ Dr. ST~.w,urr. Is the question, Where did we get the information about meu nerer smoking'.~ - Mr. Hu~,~,. Yes. Dr. Svew.~ev. There has been a multiplicity of studies. Mr. HUL~. Going to other people rather than going to the people • that smoke. Dr. Sr~w,~r. You mean going to nonsmokers ~ Mr. Hu~,~. Yes. - Dr. S,~wA~. How would we go to nonsmokers to find out l ]~Ir. Hw~,. I don't "know but you wo~ld find a way. Dr. ST~w,~az. I just don't understand your question. Mr. HvL~. Isn't it also a fact that the person being interviewed was not only charged with interpreting smoI~ing patterns but also forced "to mak_e a diagnosis with respect to such illnesses a_s sinusitis, emphy- sema, heart trouble, liver trouble, hypertension without heart involve- . ment, et cetera ? Dr. ST~WA~rr. Now you are back to the National Health Survey. Mr. Hull, I would be gla~ to provide you a series of scientific docu- ments on the sampling tecl'-'dque, the error in sampling. These have been reviewed by all tl~e sample survey designers in the United States since 1955. . Mr. HUL~. If you will. (The information follows :) ~ " " Full details of the statistical design of the Health Household-Intervlew Survey and a full discussion of methodology used in the Cigarette Smoking and Health ~haracterlstics study are found in PHS Publication 584--A2 and 1000-Series 10, No. 84. " Dr. ST~W^~T. It is true we _asked people questions_. What the National Health Survey gives you is those people that people ca.n tell you about.

" " note in the justification of the Clearinghouse that whoever wrote it could not resist the temptation to follow the Clearinghouse's tra- ditional method of exaggerating in an apparent atte.m~t to mislead the reader. For example, you talk about this report ~sued b:~ the National Center for Health Statistics which is said to show h~gher rates of disabili.ty among cigarette smokers. The justification then ~hey account for 10 percent of the ~'~ million bed days spent each year by those aged 1~' and over; 13 percent of the 2.379,000 days of restricted activity, and 19 percent of the 399 million workdays lost per year. Now, Doctor, I got the report and looked at it. I could not find a single one of those figures in it.. . Dr. Sraw,teT. Yes. That is the difference between the figures of total" bed disabilities and those of noncigarette smokers and cig~rette emokers. Mr. HvL~. MY point is_ this: I_don't think the Clearinghouse has played fair in these justifications by trying to make it avvear that its position is supported by the National Center for Health ~ati~ics, an~i by using figures that are ba~ed on a study, which admittedly doe~'t prove any cause and effect relationship bet~ sen cigarette smokin~ and disability. I would like for you to take a look at the justificatioi~ and tell me whether or not you believe it is misleading. " - Dr. ST~w,tr, r. I dont think ~t ]s m~s_leadln~,_at all~ l~.fr. Hull. The statement in the second para~'aph of the justification .is a statement of fact, that there is an associated large amount of d~sabilitv from cigarette smol~ing among the citizen.~ of the United States ak~¢l they

109 Mr. HVLt,. I note that Finland has about five times more lung cancer deaths per 100,000 men than Norway. Do you claim cigarette smoking accounts for that? " . . Dr. S~wa~rr. I would have to find out. (The information follows:) ... In response to Mr. Hulrs question with respect to the explanation for the ~vefold greater risk to lung cancer attributed to Finnish males in relation to Norwegian males, it can only be stated that at this time the Public Health ~ervlce does not have a definitive explanation. It Is true that the mortality rates reported for lung cancer in males, by Finland and Norway, are 64.5 per • 1000000 and 14.2 per 100,000, respectively. Wae National Cancer Institute has been very much concerned about the prob- lems a~soclated with differing practices in the collection of mortality and inci- dence data, both internationally and with.in nations, for the past 15 years or so. The different practices may account for the difference in the mortality rates r~ported by Finland and .N'orway, but it is improbable that the disparity can be • dismissed entlrely on that basis. Any attempt to invoke an explanation based upon genetic differences would have to account for a known remarkable similarity o5 lung cancer mortality rates between the Finnish and the Norwegian women. ~aere is me very great probability that the differences can be explained, at least "in lmrt, on differences lq environmental conditions, including personal habits end smoking practices. Mr. HwL. Would .you agree in discussing ~this question of there being a difference in populations, that people who smoke may consti- tute a very different kind of population or group than people who do not smolce~ .. " " ]Dr. S~zwa~'r. I am not sure of thati, whether that is so or not~ whether the cigarette smoking habit itself differentiates people into different groups or whether they are different themselves and tlmt is why they take up cigarette smoking and others do not. ButI do not think that has anything to do wit!~ it. " . . ~ . Mr. Ht~Lt,. Are you making an:~ studies? ..... " " " Dr. Srrw,~Rr. Yes. What we are interested in is the host factor. As I mentioned earlier there are heavy smokers who do not get lung cancer~ and there are people who are not smokers who do get lung cancer. We are interested m whether there is some factor w~thin the person himself which is prevdntive or selective. • ]~r. HULL. ]Slx't it true that many doctors think it comes front a coll.~ Dr. S~wa~r. ~No; I think most doctors think ~t comes from cigarette mnokinlz. . " . Mr. Hv~.~. Where do the youngsters, and we have thousands Of young~ters that die every year with cancer or leukemia Dr. Sz~wa~r. Not lung cancer. . ' Mr. Hv~.L. Leukemia or some other. . Dr. Sz~wA~rr. Cancer is a generic name for many diseases which may have a multiplicity of etilogies. Virus is one ~ve. are exploring very rapidly now. " . . • Mr. HVL~ In some material submitted to this committee last ye,-tr, de~ling with a so-called s.-tfer cigarette program, t_he statement is made that a prospective clinical trial to determine whether smokers dif- fered from non-smokers in important Ways other than their smoking habits should be inau~trnted. No other form of study eliminates what the author, I assume someone in the Public Health Serdce, calls the constitutional hypothesis and avoids the selfselection of smokers and nonsmokers.

Isn't it important if smoking cigarettes rosy only refl~t ~ns mo~ likely ~o get a disease ~hat ~u~ which might demon- ~a~e th~s be suppor[ed ~ ~ ~ " ~. S~w~. ~ [hink that is right, but I would like t~ ~int out ~t ~ thi~ this avenue has ~o be pursued qui~eth~rough]y.

118 Mr. ]~[~c~r~. The Public Health Service Act at section 301(i) •tates that the Surgeon General may "adopt * * * such additional means as he deems necessary or appropriate to carry out the purposes of this section." You are, I am sure, aware of the recommendation of the Fountain report, because of the abuse of this section in the making of sn un- precedented grant of $~1 million over a 5-year period to Sioan-Ketter- mg Institute, that this provision be amended to clarity and limit the authority it contains. Do you believe any clarification is necessary Dr. StewARt. Again I would refer to the Department's response to' the conmfittee's report. It is our feeling that flus particular authority was not abused in making the award to Sloan:Kettering Institute and that the type of ima~natlvc, responsive, and, therefore, produc- tive program essential to the effective use of Federal funds would be greately hampered by limiting this authority. You will note that we intended to fbrmalize to a greater extent the circumstances in which this authority is actually employed. . • . OOVF.,ILN'MENT ROLE IN ADVISING CONSUMERS Mr. M~CH~ A~n area of intensive concern for me personally and, I am sure for many other members of this committee and of the Con- gres~ is the effort which is currently being made under the guise of ~.ublic health efforts to place the Government in the role of an ad- visor on consumer products. " " A current example is the ever-increaslng involvement of the Gov. ernment in the cigarette industry. While I am not a smokeri I do realize that the cigarette industry is important to many nlillions of Americans in an economic manner and to many Americans froht the apparent pleasure derived from the use of cigarettes. I understand that not only has the Government involved itself in the identification and seeming promotion of certain brands or tyves of cigarettes having low tar or nicotine, but suggestions have'also been made by certain Government officials that lengths of the cigarettes manufactured in this country be controlled. It seems to me, as an observer, that agencies of the Government may properly be concerned with what they feel is an important national health problem and may properly advise the public of scientifically established facts. When, however, the Government~on ~-hat I am advised is less than scientific evidence--proceeds to publicize product comparisons--particularly comparisons wlfich may be misleadin_o~ I have serious reservations about where such a precedent may lead-us. Dr. S~w^Rz. The Congressmen are probabIy re~erring to the ac- tion of the Federal Trade Commission in testing cigarettes for the tar and nicotine levels of their smoke and in publicizing these results. The Public Health Service supports the Commission in its concern about the tar and nicotine levels of cigarett~ smoke and feels, in the words o~ a report ot 2 years ago, that ~rthe preponderance of scientific evidence strongly suggests that the lower the 'tar' an.d nicotine content of cigarette smoke~ the less harmful are the effects." The Service be-

A work group is ~ctively discu_ssing thi~. Thgy will be me~ting fairly. _freq. uent-ly id .t.h.e .co .ruing months...

Endicott'| let me ask you, is t_he lung cancer task force which was named on August 17~ 1967~ direct.e.d to pursue research into the causes of lung can~r~ or was it pr|marily set up to p_revent ©|garotte s_moking and to loo_~ into a less liazardous elgarette~ Which would be the road ~ou intend to travel~ . ' • : ,. ". ; Dr. E~'Dzcorr. V/ell, the task wh|oh I have assign _ed to the task re_roe m to _examine the whole problem of lung cancer and to recomr~_end to me what avenues of research they think would b~ the most productlve in brinz|nz lunff cancer under control. Part of the efforts i~ certainly go|ng t'~ b~ dire-cted towartl some improved method for -early dete~- rich. Efforts must be made to improve the effectiveness of treatment. & G.percent cure rate is simply f/ig_htful._So a s.ub.stantial part of the. efforts will have to go into the questi.on of the climcal managemen~ _of the disease when it occurs. The rest ~s aimed at trying to prevent the ~sease. We have alread~ identified some areas Where we feel real progress can be made from a research standpoint. ! will try to enumer- ate them. - - " First, of course~is the cigarette. . • " " . °- : • Second is a series of exposures which occur which we have already identified in industry. There ar~ probably others we do not Imow about but we have identified certa|n types o~exposure in industry wh|ch are clearly associated with an increase in lung cancer. The problem of the role of atmospheric pollution has to be examined intenslv-ely. There is really no doubt in my mind that this is making some contribu- tien to the pr-oblem. . Another possibility whi_ch cannot be exclud.ed is_that viruses .may p_l_ay a role and may set the stage~ so to speak~ and that these o~n_er thi/~_g?~-industrial exposure~ atmospheric pollutlon~may trigger the reaction from the stage being set b~ viruses~ but this must be actively explorec~. ' • Then, finally~ of the workers in .the ~actories ex _l~osed to the dust m~_d fumes only a relatively few of them get cancer of the lung~just as ~ela.tively few c~aretta smokers get can-c~r of the lung~ andthere ob~'musly sometlung here which determines whet.her you do or you don't.. If ~'e could reall~- find what this is we might be able to attack the probl.e.m at that point by doing something to modify individual sUS~e~ ptibility. • • So:my charge to the task for .co was to look at the.whole problem, ~ll me xvh~t am the possibilities, what they regard ss the most likely to be

So the question is an i_fly one but if I unde~ta~id the intent of your question, my feeling is that the prop~er role in thise~ort, the~proper role ~or the lung cancer task force and the National Cancer Institute, is primarily a role of biolo~cal evaluation, and that if anytldng is to be accompl.ished it will prbbably have to be accomplished by working with indwidual companies ~'ho tlxemselves are attempting to their own products, and our role will principally be one, as best we ~n~ of providing t_he biolo~cal tests ag~inst wldch they can m~sure the effectiveness of .th.e.ir manip_ulations of the product. • I had not thought ~t likely that the lung cancer task force would itself become involved in the manufacture o~ filters or of cigai'ettes or the modificatio~t of tobaccos~ tobacco culture and curing.

Only when the shape of the lung cancer mortality curve by age is markedly displaced or other~vlse changed (as may prore to be the ca~for .uranium miners) could a pro- nounced shift In average age at death result. . Because the average age at death has been an insensitive and inadequate indicator of the magnitude oF changes In lung cancer risks, the studies conducted by the National Cancer Institute have emphasized more direct comparisons based an age-specific evidence.and mo.rtallty rates. .. Mr. Hm~ Is it not true that in the ~ of workers who h~.ve • _~pcs~_d to radloac_tive_ materials or chemicals which cause lung cance_r, that t_he age at which t_hey develop lung cancers does apl~ar to_be ~_lated to_ the amoun_t of exposure they l~ave had to these materials; that is~ the greater the exposur~ the earlier, lung cancer occurs~ Dr..Em)~co~. I. could gt~ve you an impression, bht I would rather ~e~kit and putit m the record. " . ..., " - . . It ~ true that workers exposed to radioactive materials develop lung cancers at an earlier age, related quantltatlvely to the amount of exposure they have had to the radioactive materials. ~-ais Is probably else true In the case of workers ~ to a chemical/Industrial atmo~phere, but the difficulty in quantltatlng men's exposure to chemicals makes this a quallaed answer.

In emphysematous lungs, the walls of the avcoll are irreversibly destroyed and broken down, resulting in large, lnei~clent ~lr spaces devoid of small blood ve~els. 5~e flow ot air is resisted, gas exchange impaired, and breathing becomes tremely strenuous. Meanwhile, the heart must pump harder to circulate oxygen- poor blood to body tissues. I! the p~tlent is untreated or treated too late, he may. suffocate or die ot an overworked heart. -" To provide hope and relle! to those disabled by emphysema, research has been conducted .and supported by the Public Health 8ervlce-.-lneluding the .N'ational /nstitutes of Health~ln the early detection and treatment of the disease.

However, it is also .recognized • .. that ~o reduce,the rate of death ~nd dis~blli.ty, Inten~ifled efforts must be focused • ... on.research Into the cause azd prevention of the disease. . T~e cause or causes of emphysema ~re ~not now known. At one time; it was" considered a disease entity affecting only the aveoll, tiny air sacs clustered ~tround the ends or the bronchial ~ubes deep In the lung ti~ue. However, some scientists ~ow suspect 4:hat emphysema is ~ctu~lly .a cluster of Conditions possibly pre- elplta,ted by n aeries of "Insults" to one or more portion of the respiratory tract. These Insults may be acute viva| and bacterial infections, allergic .reactions such as ~bma and hay fever, or. the Inhalation of noxious agents such ms cigarette smoke or the soot and fumes o1~ urban environments. Other lnvestlga~;or~ believe that substandard living conditions ~xud genetic factors may contribute .to chronic obstructive re~plratory disease conditions. ~ sr~a~c~ ~os causes The 89th Congress, recognizing the need for a program of basic .rese-~rch with a long-term goal o~ prevention, appropriated an additional $1 million to the l~.a~ior~al Institute of Allergy -and Infectious Diseases, for Investlgations into the ~tuses of emphysema. In this effort, ~e strategy of the Institute has been to utilize the interrelated disciplines of .allergy, immunology, virology, pathology, mlcroblology, and cellular biology. NIAID grantees at the University of Colorado 5Iedical Center have maintained an emphysema registry for the past 10 years In an effort to obtain data for testing the hypothesis that a number of different acquired disease conditions are involved In emphysema. In monitoring thelr registry, the sclentlsts have discovered that many deaths actually attributable to emphysema and chronic bronchitis find their way into "vital statistics records as deaths due to such L~soclated conditions as pneumonia, heart failure, and ~ometimes stroke. In their recording of the nature and extent of gross and minute changes in the lungs, the Colorado investigators are now beginning to relate atrophy and thlnning of airway walls to a physical flabbiness of the walls, which results in • ready collapse of the bronchial tubes on expiration. ~'beir studies also include the location, nature, and degree of airway obstruction and the effect on total lung capacity. At Harvard University and Boston City Hospital, scientists are describing the mechanism by which cigarette smoking may Impair the protective processes of the lung and thus increase its su~ceptibilityto microbial infection. They are also evaluating the effect of socioeconomic conditions on the progres- sion of chronic progressive respiratory disease. Current Indications are that the disease is more severe in lower social and economic groups. o

In their healthy state, cilia ~'lbrate and, by their constant motion propel mucous and foreign matter"(such as dust and pollen) toward the mouth where it can be removed by "clearing the throat." The Duke University studies indicate that clearance of this forel~n matter Is enhanced by water deposition, increased temperature, and breathing movement, and Is reduced by, drying. Another team of scientists--working at Hektoen Institute for Medical Research in Chicago--are also studying lung clearance and the effects of microbial agent~ on the activity of the cilia. Disappearance of particles labeled with radioactive ~old is being observed in normal subjects and In patients with chronic bronchitis and emphysema.

"~t Yale University Schcot of Medicine, scientists are" assessing the role of Tlruses, mycoplasmas, and other microbial agents In the causation of emphysema. At a nearby VA hospital patients wRh emphysema are contributing to a study of blood specimens, waste products and, when possible, bronchial secretions. " Because of the anatomica! similarity of the horse's lung to that of man~ and because pulmonary emphysema of the horse (commonly known as .the heaves) closely simulates emphysema in man---a preliminary investigation of this equine disease has been undertaken. In examining the lungs of horses exposed to urban environment and those living In rural areas.

At the University of Utah College of ~/edlcine, I~ patients with chronic bronchitis or emphysema are being studied to determlne the relaltonshlp at age, ~ex. race, resldence, and occupatloa to the diseases. ~he Utah grantees have developed a complete pulmonary function laboratory where patlents in early stages of the disease are tested and followed over many year~.

" . .' • • (}ire the committee some idea as to the use of this money and just what is being done. . " ... ~.~ - Dr. Ko~x. The lung cancer task force is concerned with initiating and supp0~rting studies concerned with identifying environmental fac- tors associated with increased risk to lung cancer, identifying the .compo.nent.s of the environment responsible for this!ncreased risk, and determining the mode of action of these agents for the purpose_ providing a firm scientific base on ~rhich to suggest methods for reduc- _~ or elfminating the hazards from the environment or protecting the ho~t ag~tinst their effects. Environmental experiences associated with an increased risk to lung cancer include urbttu residence, cigarette smoking, and certain occup.~tional exposures such as to chromates, nlcke], coking operations, asbestos, and alpha-ray emissions as .occur in uranium ~ines. The lung .cancer task ~orce proposes to initiate ~dies concerned with all of the environmental experiences associated with an increase_d risk to lung cancer and factors "concerned .with ~uscept~ility and resistance. In addition; resea_rch aimed at.~acilitating early diagnosis and i_mproved treatment is to b~ supported. " • In implementing _these. activitives it has already established a sub- ~ommittee concerned with the development o~ a less haz~trdous cigar. ette. This sub~mmittee is made up o~Fe_deral and hen-Federal sc~en- ~ the latter including representatives from the research laboratories of the tobacco industry. One meeting has already been held, and a O--day meeting is scheduled for May I and 2. At this time a rdview of the cur- rent_status of the problem will be completed and a series of recom- mendations for future efforts will be formulated. A plan of action to serve as a guideline has been evolved, utilizing a systems approach,. the_reby assuring the most effective utili_zation of fu'nds with pro~-m~m review procedures and decision points identified. The Division of E~- v~ronmeutal Health Sciences is collaborating w.ith the National Can- cor Institute and the National Heart Institute m this effort. • • Mr. NA'r~Hr~. I understand the lung cancer task force has proppsed t.hs investment of some $32 million, in the next 5 years in its total as- mgnment. Presumably a signific_ant percentage of that sum would be .d.dvoted to the smoking aspect of its assignment. In additiou, the Na- tional Cancer Institute, the National Heart Institute, the Chronic Dis- ease Control Center, and the Surgeon General's O~ce are requesting £~nds for research relatlng to tobacco and. health. I believe that correct, Dr. Kotin. V;'hat ~s your relation to these programs~ How does your Center fit into this ? ..... Dr. Ko~x. Our effo~'ts in this area are devoted exclusively to re- .re. arch for the purposes described in my answer to your earlier ques- tion on this subject and have no programmatic relation to the efforts- of the National Center for Chromc Disease Control The latter is con- earned with public educatlon and social aspects of b!~arette smoking as a patten~ of behador.

(The information.requested follows:) - " " .. - ~ I described in my testimony earlier, I am aware of the research program being supported by the b'atlonal Institutes of Health. In answer to the broader aspects of the question, through mY membership o~ the American Medical AS-. aoclation Committee for Research on T~bacco and Health, I am quite specifically aware of.its activltle.& This committee Is most particularly supporting rt~search In the areas of chronic obstructive respiratory dlsoas'e and degenerative resp[ra- tow changes and the cardiovascular eeeects of tobacco.. Studies are being sup- ported in private research Institutions as well as university and medical school laboratories. The Department ot Agriculture is concerned with providing bio- logical scientists with tobacco grown under controlled conditions so that the effects of genetic modification of tobacco plants as well as manipulation during growing, curing, and manufacturing can be studied. Further. studies related to the use of pesticides, suckering agents, and mlcroblolo~cal contaminants de- pond on Dermrtment of Agriculture cooperation. The Council for Tobacco Re- search (U.S.A.} is concerned with a broad program Involving the direct effects resulting from tobacco exposure as well as studies of many'human factors associated with relatively longer life and with relatively earlier death in human populations. They are trying to find out bow habits other than smoking tend to cluster with smoking or with uonsmoking or how these may serve singly or In groups as mathematical predictors of longevity. They also are supporting work to develop new mathematical methods of handing .large n~ultffactor studies in the Seld of epidemlology. • Mr. HUr~L.

879 ~ ]~[r. HIw.,L. Would you tell us how these programs are coordinated Dr. Ko'n,x. These pro~q-ams are coordlnated'by formal exchanges of information including reprint exchange ~nd conferences, by informal joint meetinff~_ and contacts, personal associations and acce~ to cane tral repositories of seientLfic information. The A.~fA Committee for Research on Tobacco and Health and the Council for Tobacco and Rese~rch exchange listlng~ of research projects by title and investl- gator. Research supported by the PHS as well as by other recognized granting agencms mcludmo various foundahons anc| other components of Government are listed in the Scientific Information Exchange. The title of the investigation, the name of t..he investigator, and brie~ ab- stracts o~ the proposed .research are avadable ~rom S.I.E. In addition, ~o~nt membe~-hip by scienti~s on several com..mittees proride~ impor- tant communication. For example, one scientist is'a member o~ the A~,[A committee, a member of the Scientific Advisory Board of .the Council for Tobacco Rescarch (U.S.A.), aud in addition serves on one o~ the advisory groups to the U'.S. Public I-[ealth Serv'ice. • In the past, X have served on tim Scientific Advisor)- Board of the Tobacco Research Council; I am at present on the A.~[A Committee on Smoking and Health and share responsibility for the NIH pr_ogram in tobacco and health. In addition, my associates and I are advisers to the D.epartment of Agriculture in relation to research support at the University of KentuckY. The lung cancer task force mem-t/ershlp in- ©ludes _representatives ~rom the Department of Agriculture, private research organizations, and the tobacco industry. Thus, coordination of these act~vlties is carried out through formal'administrative struc- tures as well as through the exchange of information resulting from publication of research findings in the scientific liter~ture. Mr. Hca.~.. Don't you believe more could be done by the Governme~it to coor~erate with ~he tobacco industry in the area of smoking and health? Dr. l~o'n~'. This is almost a l~_licy_ matter, and I am perhaps the wrong one to ask because from the days of my tobacco ihdustry re- search committee membership my relationships with the industry-have been so cordial that it has to be brought to my attention that there • eally isn't this cordiality up and down the line. • Mr. Ht'LL. ~[~" fiual c~uestJon is, what do you su~rgest to improve on thepresent situation. ...

THE AMERICAN MEDICAL 535 North Dearborn Street, Chicago, Illinois 60610 • • Area Code 312 527-1500 ASSOCIATION For A.M. Release Friday, May I0, 1968 CHICAGO--One of medical science's most intensive investigations gained additional scope today with pledges by six tobacco companies of an additional $8 million for the American Medical Association Education and Research Foundation's inquiry of smoking and health. 1973. into the relationship The new pledges assure support of the research program through All of the funds will be allocated by the Foundation to independent scientists conducting research in their own laboratories. Costs of administering the grants are paid by the American Medical Association and not from contributions. The program began in June, 1964, shortly after the ~rgeon G~n~al's Report on Smoking and Health was issued and the then- Surgeon General, Luther Terry, M.D., called for further research into the problem. Financial support c~me from the nation's physi- cians and an initial $I0 million grant from the same tobacco companies. Since then, 104 investigators or teams of investigators have been at work on the problem in 50 institutions in the United States and five foreign countries. 0

- 2- Association has repeatedly warned hazard; and this opinion has been scientific organizations. The companies aiding in support of the program are American Tobacco Co., Brown & Nilllamson Tobacco Corp., Liggett &Myers, Inc., Lorillard Corp., Philip Morris, Inc., and R. J. Reynolds Tobacco Co. Both the original grants from the firms and the new pledges were made without restrictions, said Gerald D. Dorman, M.D., vice- president of the Foundation. The only condition is that the money be used for research on tobacco and health, he said. Contributed funds go directly to the Foundation, and grants are awarded by a six-member co~,~ittee of scientiots. The committee includes two scientists who served on the original advisory com- mittee to the surgeon general. "For many years," said Dr. Dorman, "the American Medical that smoking may be a health supported by numerous other "But major questions about the problem remain unanswered by anyone--what is the exact chain of events inside the body when tobacco smoke is inhaled; which specific ills might be directly attributed to smoking; what are the elements in smoke which might create health hazards, and can these elements be minimized or eliminated?
Page 336: 502077307
-3- "~hese are ~mong the questions the Foundation is seeking to answer through basic research. "This matter of the relatlonshlp of smoking and health has become an emotion-laden issue, and the Foundation feels it is very important and that all avenues of exploratlon be kept open. Unless you have the scientific facts and explanations, you can't make absolute judgments." On June 19, a score of the independent scientist grantees from this r~atlon and abroad will report their findings to date to the nation's scientific co~unity during the AF~'s Annual Convention in San Francisco. At the same time, more than 90 additional reports will be published. Early drafts of those reports suggest several important find- ings. These include: * The most compelling evidence to date that dependence on smoking as a habit is psychological in origin, not physical. * Clinical trials which indicate that frequency of smoking can be reduced by intravenous injections of nicotine; but that two drugs widely used to help smokers quit either have no effect or may actually increase smoking frequency. * Further evidence supporting the long-held belief that patients with heart disease increase their risk of complications by smoking.
Page 337: 502077308
-4- * Extensive studies of pairs of twins, some of them smokers and some non-smokers, which indicate that genetic and environmental factors other than smoking also may play an important part in the development of angina pectorls and bronchitis. Subjects of other reports during the symposium will range from a clinical study of the effects of cigarette smoking in women to highly sophisticated physiological and biochemical studies of the effects of smoking on tissue. '~Ii of these investigations, some clinical and many quite basic in nature, add significantly to the body of scientific know- ledge about the effects of smoking on health," Dr. Dorman said. "But answers to the major questlons--what are the exact, scientifically documented effects of smoking on the human and his tissues; what, if anything, can be done to make smoking more safe-- are still inconclusive. "This reseach must be continued in the years ahead if answers are to be found." The tobacco companies, in pledging the additional $8 million grant, endorsed this goal. Five of the firms, Brown& Williamson Tobacco Corp., Liggett & Myers, Inc., Lorillard Corp., Philip Morris, Inc., and R. J. Reynolds Tobacco Co., pledged their support over the five years from 1969 to 1973. The sixth firm, the American Tobacco Co., currently pledged its support for the year 1969.

Blasingame Executive Vice President American Medical Association 535 North Dearborn Street Chicago, Illinois 60610 Dear Doctor Blasingame: I am writing you to give you my thoughts regarding my Company's continued participation in the work of the American Medical Association Education and Research Foundation to which tobacco companies have been contributing under a five-year grant that ex- .pires with 1968. In this connection, I have had the benefit of a report by Mr. C. F. Hetsko, our Vice President and General Counsel, of the discussions at the recent meeting in Chicago at which I understand there was a consensus that smoking and health ques- tions have not been resolved and that additional research is indicated. I also understand your own feeling to be that research will be far from completed by the end of the present grant period. With these considerations in mind, we are pleased to advise that for 1969 we will continue to contribute on the same basis as heretofore, namely, $500,000. We will then again consider the progress being made and what our further contribution to the research program may be. This arrangement, X hope, will be satisfactory to you. In closing, let me say that we here very much appre- ciatethe constructive attitude with which we under-

Walker President and chairman of the Board The American Tobacco Company 245 Park Avenue New York, New York 10017 296-8434 Dear Barney: I have given considerable attention to your letter of January 2, 1968, concerning continued support of the American Medical Association Education and Research Foundation Project of Tobacco and Health--which letter, as you may know, was delivered to me only upon my return to the office after gaining doctor's approval. Pursuant to your suggestion, I have taken this matter up with the other five companies. I am glad to report that the industry appears to be nearing a consensus. More precisely it appears that four of the other five companies favor another five-year commitment. The other company presently prefers a commitment for three years. I gather from your letter that you are thinking in terms of five years also. As to the amount of annual dollar contribution, the other five companies incline to the same total amount per year as heretofore; whereas your letter indicates a preference for a reduced total annual contribution. Speaking as one of your representatives, I believe that. the willingness of the A.M.A. to endorse another five-year program of the same total amount is a clear indication to the public that, in their judgment, a real controversy exists, the answers are not in, and they will not be in for many years. While I would not say that a shorter period or a
Page 349: 502077320
Mr. Robert, S. Walker - 2 - February 24, 1968 reduced dollar volume of support would completely destroy those benefits, it does seem to me that it puts the industry in the position of saying that the problem is not as complex or as difficult to solve as the A.M.A. is prepared to admit. Obviously it disadvantages us to minimize the complexity of the problem. I shall be glad to discuss this matter with you by tele- phone, or when the doctor permits me to travel, if you wish, I will come.to New York. On the other hand, it occurs to me that you may wish to invite the other chief executives to meet with you for a discussion of the matter. Kindest personal regards.

March 26, 1968. American Medical Association Education and Research Foundation, 535 North Dearborn Street, Chicago, Illinois. 60610. Gentlemen: The undersigned companies and TheAmerican Tobacco Company in their joint letter to you dated January 31, 1964, severally expressed their willingness to contribute to the Foundation during the period 1964 through 1968 the total.of ten million dollars to be used together with other funds made available for the purpose in financing the research project proposed by the Foundation to determine which significant human ailments may be caused or aggravated by smoking, how they may be caused, the particular element or elements in smoke that may be the causal or aggravating agents and methods for the elimination of such agents. Acceptance of the offer of the various companies was expressed in your letters dated February 12, 1964 to each of them. In our recent discussions in Chicago, the Foundation indicated the inconclusiveness of research to date and the necessity for continuation of research in the years ahead if answers are to be found. To enable the Foundation to plan for and continue sponsorship of needed research the companies involved were requested to continue beyond 1968 their financial support of the research project. The undersigned companies are willing, upon the same terms as set forth in the letters dated January 31, 1964 and February 12, 1964, to continue their financial support of the research project during the period 1969 through 1973 by contributing a total of $7,500,000, the contribution of each of the undersigned companies not to exceed the amount set underneath its name. The contribution of each would be paid in approximately equal annual amounts. It is our understanding that you have received a commitment from The American Tobacco Company to support this research by an additional contribution of $500,000 to be made in 1969. Hopefully that Company will renew such contribution

Tobacco & Health "2- Council for Tobacco Research American Medical Association Mr. N. T. Hoyt Executive Director Dr. Robert Hockett Scientific Director Milford O. Rouse, M.D. President F. J. L. Blaslngame, M.D. Executive Vice President Ernest B. Howard, M.D. Assistant Executive Vice President Charles L. Hudson, M.D. Immediate Past President and Director, Div.. of Health Service Hugh H. Hussey, M.D. Director, Div. of Scientific Activities Ira Singer, Ph.D. Secretary, Committee for Research on Tobacco and Health INTRODUCTORY REMARKS Dr. Rouse called the meeting to order at 1:30 p.m. and expressed the AMA's appreciation that the representatives of the tobacco industry had come to meet with the Committee to evaluate the goals and progress of the Project for Research on Tobacco and Health. He commented that in his travels as President of the Association he had found genuine interest in, and approval of, the search for evidence which the industry is supporting through the Foundation. Dr. Blasingame indicated that the Board of Trustees had instructed him to initiate a discussion of the cooperative efforts between the tobacco industry and the Foundation during the last four years and the future of this relationship. This meeting was arranged to give the industry representatives an opportunity to meet the advisory committee and to discuss its activities--especially the "progress report" to the public, industry, and profession whichwill be included in the program of the Council on Scientific Assembly at the AMAAnnual meeting in San Francisco in June--and, from an administrative standpoint, to ascertain whether this program will be continued, modified, expanded, or phased out.
Page 355: 502077322D
Tobacco & Health -3- Dr. Seevers reported that theCommittee had viewed the problem of tobacco and health as a whole to determine the most effective use of the industry's contribution. Within the context of the large amount of Federal funds available at that time for all types of research and the level of support for work in carcinogenesis, the Committee decided to concentrate its efforts on fundamental cardio-vascular, respiratory, and psycho-pharmacological research. It sought particularly to support ongoing projects by clinical investigators with demonstrated capabilities in these limited areas. The Committee would continue to follow these general concepts, with the addition of a fellowship program intended to increase interest in this field. Dr. Hudson stated his belief that the objectives of this program were worthy of further pursuit inasmuch as other approaches to the problem had proved unsatisfactory. Dr. Blasingame added that his correspondence and comments made to him suggested that the reasons for the joint endeavor were better understood and that the AMAposltlon had been strengthened. The AMA has conducted an.approprlate health education program directed at young people but maintains that no causal relationship between tobacc4) and health has been demonstrated and further research is necessary to elucidate any which might exist. Traditionally, such debate should be carried on through the AMA's scientific publications and not through the mass communications media. DISCUSSION OF PROGRAM San Francisco Meeting Dr. Seevers reported that the Committee had received two abstracts from each of its grantees and would select eighteen to twenty papers representing the basic and clinical aspects of the problem to be presented at the day-long open meeting. During the final hour, a panel of four people will summarize these observations and suggest future objectives. The brief abstracts will be published in the general program and the more detailed reports on the status and progress of the individual projects will be published in a separate book.
Page 356: 502077322E
Tobacco & Health -4- Publication of Research: In response to Mr. Smith's question about the Con~nittee's intent of publishing negative as well as positive results~ Dr. Seevers pointed out that the Co~nlttee has no mechanism for this and that only the editors of the scientific journals to which grantees choose to submit their manuscripts are in a position to make this decision. Dr. Hickam added that a grantee would feel some compulslon to publish unexpected answers in order to convince the Committee that his accomplishments merited continued support. In answering a subsequent question from Dr. Hockett, Dr. Seevers indicated the Committee had discussed the possibility of publishing an annual report but concluded that its program had not been in operation long enough to prepare a meanlngful evaluation. However, the reports from the San Francisco meeting should constitute such a summary. Dr. Singer described the procedures followed after the Committee recon~ends approval of an application, emphasizing that the grants are subject to annual renewal and this is based on the investigator's report of his progress--positive or negatlve--and that this material is available upon ~equest. Status of Project Dr. Seevers reported that almost $7 million of the origlnal contribution had been committed. In response to Mr. Yellen, he indicated that the Committee had been able to approve grants considered worthwhile; it rejects about half of the some twenty applications submitted to it each quarter. Dr. Singer has en- deavored to interest deans of medical schools and particularly well qualified scientists in this program although the Committee does not automatically approve solicited applications. Recent awards have averaged $50,000 - $i00,000 over a two- to three- year period. Areas of Research Mr. Hetsko asked the Committee, on the basis of their previous experience with this program and their knowledge of recent developments in the areas they had been supporting, if it intended to continue to direct its funds into these fields or if some would be emphasized more than others.
Page 357: 502077322F
Tobacco & Health -5- Dr. Kotin agreed that the establishment of some priorities was inevitable in approving some applications but not others; however, the Committee is limited by the requests submitted to it. In judging these applications, the Committee also considers the merit of the work, the competence of the investigator, and the relevance to the goals of the Project. Cancer: Dr. Seevers explained that the Committee had emphasized areas other than cancer research because of its inability to compete with existing large-scale efforts and the difficulty of discriminating between problems related specifically to tobacco and those concerned with carcinogenesis of neoplasms. Nevertheless, Dr. Kotin stated that the Committee had supported some excellent research related to this problem although their relevance is not apparent, from their titles because they are con- cerned with the cellular response to cancer. One investigator has been engaged in an attempt to determine if enzymatic defenses can be enhanced sufficiently to protect animals exposed to carcinogenic chemicals. Another study has traced the biological path followed after an agent attacks the receptor site within the cell in order to elucidate the mechanism of clearance. Cardio-vascular: With regard to cardlo-vascular research, Dr. Bing mentioned that a study supported by the Committee had produced the significant discovery that circulation in the normal system is not impaired by smoking, whereas it is in a diseased one. Respiratory: Dr. Hickamcited a recent discovery in this field which associates the lack of a specific i~,nunoprotein with the early development of emphysema regardless of whether the individual smokes. The Committee has just made a grant for a survey of immunoprotelns in the blood to learn if there are other related abnormalities and to determine if there is a segment of the population which is more susceptible to emphysema. Psyc~opharmacological: Dr. Seevers described some of the psychological approaches, pointing out that smoking is a partly psychological and partly pharmacological drive. That nicotine does not produce physical dependence has been reasonably well established in lower animals but the data are difficult to extrapolate. Moreover, it has been necessary to establish more
Page 358: 502077322G
Tobacco & Health -6- sensitive methodology to determine the amount of nicotine in circulating blood and its fate in the body. A current study has shown that an intravenous injection of 4 mg of nicotine per hour is necessary to affect the smoking patterns of human volunteers. Increases in heart rate and blood pressure suggest that one of the drives to smoke may be a blood pressure too low to be comfortable. Evaluation Mr. Rammasked the Commlttee to comment on the criticisms of individual projects raised by members of his scientific staff. For example, he questioned .the advisability of grants to study the influence of nicotine on HC1 secretion by the stomach, and the effects of nicotine on histamine levels. Dr. Larson objected that the abstracts and titles distributed to the industry were an inadequate basis for such judgments, pointing out that the HCI study was an attempt to understand the mechanlsm involved in this phenomenon. Dr. Kotln affirmed that the elegance of the actual experimental protocol is the crltlcal basis for evaluation. Because of the wide spectrum of response to Insult found in any population, it is imposslble to identify the individual who is at rlskunless the fundamental mechanism is understood. In reply to Mr. Hetsko's inquiry about the results from the $400,000 grant on smoking and cough presently being terminated, Dr. Hasterlik reported that in reevaluating this work, which was designed to analyze patterns of sound and describe the different phases of cough related to differences in abnormal pulmonary function such as chronic bronchitis, the Committee felt it had produced some important information but the potential yield was not as profitable as other possibilities and consequently this grant was cut back. Liaison withCouncll Staff of both.groups concurred that in spite of some duplication of support at the time the project was initiated, they have effectively discouraged investigators from applying to both organizations. In addition to the staff communication, there is an overlap in membership
Page 359: 502077322H
Tobacco & Health --7-- on the advisory committees and better methods of screening applications have been developed. However~ Mr. Hoyt stressed the need for awareness of possible complications as the reduced availability of Federal ~unds increases the number of applications submitted to the two tobacco groups. SUMMARY On behalf of the Committee, Dr. Seevers expressed the hope that it would be possible to continue the present program and to pursue the exploration of the many remaining unsolved problems in this area. It is felt that"such support from the private sector will be increasingly important, both because the government has reduced its spending and because this approach enables the investigator to plan his research more than one year in advance. Mr. Ramm thanked the Committee for the opportunity to meet with them and indicated that the decisions of the individual companies with regard to authorizing further support would be communicated to the AMA as promptly as possible.

EVALUATION OF PHYSICAL DEPENDENCE. PSYCHOGENIC DEPENDENCE AND TOLERANCE TO NICOTINE IN THE MONKEY~ O. A, Deneau,~ Retzo In.okts. and Daniel E. BrLtton Department of Pharmacolog),o The Untverstt~ of MtchL~n Medical School Ann ~rbor. Michigan These h~vesttgattons were designed to determine which of the more common elements of drug abuse, ff any, are attributable to nicotine. In the study of phys..lcal dependence, 4 groups of § monkeys each were used. Ono group received 118 mg/kg nicotine sc every 6 hours for 90 days (calculated to be roughly equivalent to the nicotine absorbed by a ~.-pa~,keoa-day smoker). The second group received 9./$ mg~kg sc every 6 hours for 90 days. The third group received 9./3.mg]kg sc every 0 hours inttislly, but the dose was raised as rapidly as possible consonant with good health of the monkeys. This " group was treated for 7 months, the ultimate dose being 17 mgIkg every (} hours. The fourth group was not treated -- it served as a growth-rate control group. Water solutions of the'a~kaloid were used throughout in concentrations such that the dose per kilogram was always contained tn 0. 9.5 co. A 48-hour test withdrawal w~s conducted after one month of treatment, The group on the ascending ~tose was withdrawn for 6 days at the end of three months before treatment was resumed. No outward signs indicative of an abstinence syndrome were observed in any group at any withdrawal period. It must be concluded that physical dependence to nicotine did not develop under the conditions of this experiment, Tolerance developed to several of the effecis of nicotLne such as increased heart rate, respiratory rate, emesis, and convulsions.. The tolerance, 5020"/ ?320,

After a period of chronic dosing and then withdrawal, the monkeys lost their tolerance and, in fact, became supersensitive to nicotine in 24 hours. The supersensitivity' persisted for 7o10 days. Although the LDs of nicotine was not determined, reports in the literature, coupled with experience from ace|dental overdosing, indicate that the LD~o is below |7 mg/kg, which was salt|safely attained in the chronic studies. From this, it is assumed that tolerance also develops to the lethal effect of nicotine. " P'sychogenlc dependence may be sa|d to have been demonstrated ff a monkey voluntarily initiates and maintains self-administration of a drug. In one o ¢ experiment, nine monkeys, housed lnd|vldually, .had a choice of drinking tap water or solutions of nicotine water. The consumption of both was recorded. In concentraUons up to 100,, gm/ml of nicotine, the monkeys appeared to be unable to discriminate between nicotine solution and tap water. monkeys developed an aversion for the nicotine solution. At 400. gm/ml, the There was no clear evidence of psychogenic dependence to nicotine in this experiment. In another experiment, 7 monkeys were prepared with intravenous catheters and by pressing a lever they could activate an injector to deliver an intravenous dose of nicotine. If the monkeys did not spontaneously initiate self- &dmb~istrat|on, injections were automatically delivered at hourly intervals by • timer mechanism. In this mode of operation, the monkeys could take supple- ss~entary hlJectiorm by pressing the lever. At a dose of I0 p grn/kg, none of the

When the dose w~s raised to 25 p gm/k~ 2 of the monkeys initiated self-lnjectlon; and with periods of priming, ranging from 2 to |0 days. t~e other 5 n~'~nkey~ began to self-ad~....i;~i.~ter ntcotL~e. At Intervals of approx- lxnately one month, the individual dose~ were raised successively to 50. 100, 200, 500, 10~) and 2000/~ gmlkg.

PULMONARY FUNCTION BEFORE AND D~ING THE COURSE OF PROLONGED ABSTINENCE FROM SMOKING IN A GROUP OF CHRONIC SMOKERS Richard A. Krumholtz and Joseph C. Ross (grantee) Department of Medicine Indiana University School of Medicine Indianapolis, Indiana Certain aspects of pulmonary function in chronic cigarette smokers have been sho~J~ to be different from those found in a similar group of non-smokers, the smokers' functions tending to be less normal than the non-smokers'. In a previous study we found that short term abstinence from smoking minimized these differences. The present study was undertaken to evaluate pulmonary function during long term abstinence from smoking in young cigarette smokers who have smoked at least 5 years and compare the results with parallel studies in non-smokers and smokers who continue to smoke, and who are in the same age group. Three groups of subjects, then, are being utilized: I) non-smokers, control, 2) chronic cigarette smokers who stop smoking, 3) chronic cigarette smokers who continue smoking, control. We plan to incorporate 20 to 25 subjects in each group. Measurements are being made at 0, 1½, 3, 6, 12, 24, and 36 months in the smokers who quit and 0, 6, 12, 24, and 36 months in both groups of control subjects. Lung volumes, spirometry, mechanics of breathing, dis- tribution index, response to exercise, and pulmonary diffusing capacity (DLco) are being determined. At this time 3 smokers have completed 6 months of abstention from smoking. With this small number, only general statements as to trends of functional change can be made, but all three subjects have had increases in total lung capacity, functional residual capacity, and residual volume after 6 months. Maximal voluntary ventilation and FEV200_I200 were also elevated in 2 subjects at 6 months. Airway resistance was reduced in all 3 subjects at 3 months and in 2 subjects at 6 months. DLco at rest and with exercise was increased in 3 subjects at 6 months. These preliminary studies in the 3 subjects who have completed 6 months of abstinence from smoking demonstrate that certain functional changes take place in the lung of the chronic smoker during a period of 6 months abstinence from smoking.

RADIOISOTOPIC STUDIES OF THE EFFECTS OF CIGARETTE SMOKING UPON DISTRIBUTION OF PULMONARY VENTILATION AND BLOOD FLOW Kenneth M. Moser (grantee)and August Miale, Jr. Department of Medicine Georgetown~ University Hospital Washington, D. C. This project will combine radioisotopic and pulmonary functional technics to determine: (a) the effects of acute and chronic cigarette smoking upon ventilation and blood flow in the lung; (b) the correlation between such effects and alterations in spirometric performance and arterial blood gas values; (c) pharmacologic and other methods which may prevent or reverse the effects observed. Initial studies will involve perfusion and inhalation .radioscans, utilizing the scintillation camera (SC), in normal subjects and patients with chronic obstructive pulmonary disease. Such subjects also will be studied by standard spirometric technics and (resting) values for arterial Po2, Pco2 and pH. During this control phase, developmental efforts will include: preparation of Tc99m albumin macroaggregates; study of the influence of various technical factors on inhalation scans; evaluation of special methods for improvement in the quality of data provided by both perfusion and inhalation Further phases of the investigation will be concerned with sequential studies (spirometric, blood gas, inhalation and perfusion scans) in subjects with and without pulmonary disease before, during and after cigarette smoking.

ACUTE EFFECT OF CIGARETTE SMOKE ON LUNGS OF RABBITS (A NEW HISTOLOGICAL TECHNIQUE) William H. Anderson Department of Medicine University of Louisville Louisville, Kentucky A technique of fixing cubic centimeter specimens of lung in the inflated state has been developed. This is accomplished by exposing the extirpated piece of lung to 100% CO2 at atmospheric pressure. The lung specimen expands spontaneously arid is then fixed in the expanded state by flooding the specimen with 10% formalin saturated with 100% carbon dioxide. This histological technique was used to examine the lungs of rabbits which had been exposed to cigarette smoke. The rabbits were anesthetized, respiration paralyzed, and a burning cigarette placed in the inspiratory side of the circuit of an intermittent positive pressure respirator. Control animals were treated in a similar manner with the respirator, but were not exposed to cigarette smoke. The following changes were observed as a result of acute exposure to cigarette smoke:. 1) Disruption and distortion of the general architecture of the mucosa and submucosa of the bronchi; disruption of the bronchial epithelium, vacuolization and swelling of cells with actual breakage of cell membranes. 2) Infiltration of monunuclear cells in the submucosal, peribronchial and interstitial spaces. 3} Parenchymal atelectasis with alveolar exudation and hemorrhage. 4) Desquamation of large, swollen, granular filled cells (granular pneumonocytes) into the alveoli. 5} Macrophages and round cells were also found to enter the alveolar spaces in large number. 6} Fraying. and spreading apart of the collagen bundles in the alveolar walls and the submucosa of the bronchioles was demonstrated by the trichrome stain. 7) Even though these extensive changes in the lungs were found, there were not profound changes in arterial pO2 or pCO2. However, the animals developed a marked metabolic acidosis and a significant decrease in cardiac output preceding death.

SMOKING AND COUGH R.G. Loudon Department of Medicine University of Texas, Southwestern Medical School Dallas, Texas The relationship between smoking and cough is being studied, using several avenues of approach. Specific items under study include: (1) The frequency with which smokers and non-smokers cough. (2) The relative strength of various factors affecting cough frequency in healthy smokers and healthy non-smokers. (3) The acoustic and physiologic characteristics of cough in smokers and non-smokers without overt respiratory disease. (4) The frequency and other quantitative characteristics of cough in.patients with various respiratory diseases, in relation to smoking history. Interim analysis of the first two items has revealed several points of interest. While cough frequencies vary considerably from one situation to another, those who smoke during the period of observation cough about twice as often as those who do not smoke. The ratio of cough. frequencies in smokers and in non-smokers is remarkably uniform for the varied situations observed. Factors other than smoking which influence cough frequency include sex, time of day, season of the year, and observational situation. The study of acoustic and physiologic characteristics of cough in smokers and non-smokers with and without respiratory disease is progressing favorably. Methods have been evolved to measure flow rates, esophageal pressure, volume expelled, air flow resistance, and work on the lungs during coughs and during maximal expiratory efforts. Methods and results will be described. Cough frequency has been measured in patients with a variety of respiratory diseases. The three main disease categories studied are pneumonia, chronic obstructive respiratory disease, and pulmonary tuberculosis. Mean cough frequencies per hour for smokers and non-smokers respect- ively in these disease groups are: pneumonia, 17.0 and 11.6, chronic obstructive respiratory disease, 26.8 and 43.5 (only two cases in non- smokers), pulmonary tuberculosis 7.5 and 4.5. Results will be presented by sex and by severity of disease. Implications of results will be discussed, and plans for future studies presented. 0

CILIOSTATIC EFFECT OF PHENOL AND RESOHCINOL Tore Dalhamn Institute of Hygiene, Karolinska Instituter Stockholm, Sweden Several substances have been reported as taking an active part in the ciliostatic effect of tobacco smoke. One of those attracting particular interest is phenol. Experiments with this substance have been conducted mainly on frogs or on lower animals such as mussels. The present authors have aimed at producing a method for screening tests on the tracheal mucosa in vitro from mammals. The effects of phenol and resorcinol (in various concentrations) have been compared, which is interesting in that it is only a hydroxyl group which distinguishes these two compounds. The results suggest that phenol is more ciliostatic than resorcinol.

EFFECT OF TOBACCO SMOKE ON RESISTANCE TO RESPIRATORY INFECTION Arnold Spurgash and Richard Ehrlich (grantee) Life Sciences Division IIT Research Institute Chicago, Illinois A study was undertaken to determine whether tobacco smoke can change innate resistance to respiratory infections. Two experimental protocols are utilized. In one, Swiss albino male mice are challenged intranasally with Diplococcus pheumoniae type II, III, or VII and then exposed to cigarette tobacco smoke 1 or 24 hours later. In the other, mice are exposed to cigarette smoke and then challenged intranasally with D__:_. pneumoniae 1 or 24 hours later. Control mice exposed to cigarette smoke only or challenged with D. pneumoniae only are included in each experiment. A specially designed smoking apparatus generates the cigarette smoke into a Lucite animal chamber, which houses the mice during exposure. The duration of smoke exposure is 1 hour, and the quantity of smoke is equivalent to 20 cigarettes. There was no statistically significant difference in the mortality or the survival time of mice challenged with D._~=_pneumoniae only and those challenged and then exposed to cigarette smoke. Likewise, there was no statistically significant differences between the mice challenged with D._:.. pneumoniae only and those exposed to cigarette smoke and then challenged with D..~neumoniae. No deaths occurred in mice exposed to cigarette smoke only.

SURFACTANT EFFECTS OF CIGARETTE SMOKE Watts R. Webb Department of Surgery The University of Texas Southwestern Medical School Dallas, Texas The surfactant effects of cigarette smoke on minced rat lung extract and dog and human bronchial washings have been evaluated utilizing a modified Wilhelmi balance. Cigarette smoke reduced the surface tension of rat lung surfactant from an average 55 dynes/cm at full area and 9 at 20% area to 38 and 17 respectively. Human bronchial washings were comparably altered in surface tension by exposure to cigarette smoke. Bubbling the smoke through water did not change its effect at all, presumably because large bubbles do not allow removal of the smoke particles. Use of a Sentering bubbler partially removed the smoke effect and filtration of the smoke through millipore filters (0.45 or 1.25 microns) removed all the effects of the smoke so that the filtered smoke produced no alteration of surfactant. This effect possibly could be due to either a chemical or a nonspecific dust effect since the effective chemical (if present) could be carried by the smoke particles. Interestingly, dust from the laboratory floor was found to alter the surfactant curves in much the same manner as cigarette smoke. Likewise, cigarette smoke bubbled through saline caused a marked reduction of its surface tension with a surprising degree of hysteresis. This reduction of surface tension, if similarly noted in the alveoli, would reduce their expulsive force in exhalation and tend toward emphysema, which is freq,~ently associated with chronic cigarette smoking. Washings from chronic cigarette smokers taken during a routine smoking day likewise had a significantly reduced surface tension and stability index. Also washings taken immediately after a cigarette showed a more abnormal curve than those taken after a period of abstinence.

EFFECTS OF CHRONIC NICOTINE ADMINISTRATION ON MULTIPLE MOLECULAR FORMS OF MYOCARDIAL ENZYMES Duane G. Wenzel Department of Pharmacology University of Kansas, School of Pharmacy Lawrence, Kansas Unpublished studies from our laboratories have demonstrated that the chronic administration of nicotine to rats produces a significant reduction in myocardial aspartate aminotransferase (AAT). An initial elevation is produced by a dose of 2.28 mg/kg/day (2 pack equivalent). This effect is blocked by either puromycin or ethlonine and the block of the latter reversed with methionlne. The stock colony of Sprague-Dawley rats was lost following the initial results and rats of this strain from other colonies have not demonstrated the.observed sensitivity to nicotine. Studies are currently underway to explore theuse of other strains of rats and to sensitize Sprague-Dawley animals through mild stress. Animals are to be chronically treated with two doses of nico- tine, 0.14 and 2.28 mg/kg/day, in their drinking water. These doses approximate the effect of nicotine obtained f~om one-elghth and two packs of cigarettes. Groups ofanlmals will be sacrificed at intervals of one to one-hundred and eighty days. Both AAT and lactic dehydrogenase and their Isozymeactlvltles will be deter- mined with entire hearts. A preliminary study with ~cute doses of catecholamlnes has shown a shiftln myocardial isozymes toward the skeletal muscle form. • Further objectives of the study are to evaluate the mechan- ism of possible nicotine-induced effects through the use of block- ing agents~ and with adrenalectomlzed and hypophysectomlzed rats. Catecholamine concentrations of the heart are to be determined in relation to isozyme patterns. Other multiple molecular forms of enzymes are to be similarly evaluated. 0

THE EFFECT OF NICOTINE ON MYOCARDIAL METABOLISM Norman Brachfeld Department of Medicine Cornell University Medical College New York, New York Mechanisms responsible for the apparent cardiac toxicity of nicotine are unknown. In brain, nicotine toxicity may be expressed as interference with cellular respiratory metabolism. Experiments to determine the effect of this agent on myocardial lysosomal, mi~o- chondrlal and supernatant enzyme systemswere performed in the isolated flow demand perfused rat heart. Control perfusions were compared to hearts perfused with Krebs Ringer buffer containing 5.5 mMglucose + 2~0 ~g. nicotine base for 30 minutes. Nicotine caused a highly significant release of acid phosphatase and ~-glucuronidase into the perfusate (96%, 53% > controls, p < .001). Perfusate concentration of lactic dehydrogenase increased 263%. Cytochrome oxidase concentration was unchanged. ~here was a 100% increase in lactic acid production with an associated 52% increase in glucose consumption and increase in QO2. Heart rate increased 24%. pH, perfuslon rate and other performance characteristics were unchanged. Response was fixed through nicotine concentrations of 2.0 to 20 ug/ml. Our data indicate that nicotine stimulates myo- cardial anaerobic metabolic rate and inhibits HLac oxidation. Evidence suggests the mechanism to include inhibition of DPN depen- dent dehydrogenations without inhibition of electron transport or mltochondrial integrity. Mechanisms responslble.for increased lysosomal fragility and increased permeability of the cell wall to LDH will be discussed.

EFFECT OF NICOTINE ON INCORPORATION OF CI4-AMINO ACIDS INTO PROTEIN Slgmundur Gudbjarnason Department of Medicine Wayne State University Schoolof Medicine Detroit, Michigan The effect of nicotine on in vitro incorporation of cl4-amlno acids into cytoplasmic and nuclear protein of heart muscle has been studied. In an aerobic system, .there was no effect of nicotine (1.5 x 10"4M) on incorporation of labeled aminoaclds into heart muscle protein. In an anaerobic system (KCN) the addition of nlco- tlne significantly increased the rate of incorporation both into cytoplasmic as well as nuclear protein. The effect of nicotine was also studied in presence of added G-6-PDH, since nicotine has been reported to activate G-6-PDH. The addltlonof G-6-PDH signifi- cantly reduced the rate of incorporatlbn, but nicotine again stimu- lated the incorporation to the same extent as before. The effect. of nicotine on the reaction rate of G-6-PDH .(from hearts brain, and liver) was studied, but no effect was observed with the direct spectrophotometrlc method. Addition of TPNH (NAPDH) (10"3M) inhibi- ted significantly the incorporation of cl4~amlno acids into nuclear. protein, both in absence and presence of KCN, whereas the incorpora- tion into protein of the cell-free supernatant was only inhibited in presence of KCN. Nicotine again effected an increase in incorpora- tion in a system containing both TPNH and KCN, particularly in the cell-free supernatant. It is tentatively concluded that TPNH may regulate certain reactions of protein synthesis as indicated by the inhibition of cl4-amino acid incorporation upon addition of TPNH or TPNH-generating system and KCN. Nicotine seems to be able to stimulate the oxidation of TPNH to TPN+ and thus indirectly • stimulate incorporation of cl4-amlno acids into protein. If this hypothesis is correct, nicotine might influence metabolism of ster- oids and llpids via TPNH. An investigation of the effect of nicotine in vlvd on protein and nucleic acid synthesis in heart muscle and on.enzyme patterns of heart, brain, and liver, is in progress. In these experiments the nicotine is administered to several groups of dogs, the first group receiving 50 ~g/kg 5 times a day for 3 months. The dose has been increased and presently animals are being studied that have received 400 ~g/kg 5 times a day for 3 months. These studies are still in an early stage and therefore inconclusive.

CATECI~OLAMINE METABOLISM FOLLOWING CIGARETTE SMOKING AND NICOTINE ADMINISTRATION Thomas C. Westfall Department of Pharmacology University of Virginia Schoolof Medicine Charlottesville, Virginia It has previously been observed that cigarette smoke inhala- tion and nicotine administration results in an increase in the epine- phrine (E) and to a much lesser extent noreplnephrlne (NE) content in the blood and urine of man and experlmental.anlmals. Although the amounts of free E and NE excreted in the urine are very constant they represent only 3-6% of the total excreted amine. The majority of amine is recovered as the o-methylated metabolltes metanephrine (M) and normetanephrine (NM) or .3-methoxy-4-hydroxy mandellc-acld- (VMA) as well as minor amounts of other acld and conjugated metabo- flies. The present expeflments were carried out to study the effect of nicotine and cigarette smoking on the major catecholamlne (CA) metabolites as well as the important precursor dopamine in order to further supplement our knowledge of the action of nlcotlne.on the sympatho-adrenal system. Rats were placed in individual metabolism cages and allowed 507 days for accllmitization to their enQironment. Twenty-four hour urine samples were then collected before and after the adminis- tration of various doses of nicotine. Each rat thus served.as his own control. One aliquot of the urine was taken and used for.the extraction and determination of VMA acc0rding..to'the method of Pisano et al. (Clin. Chim. Acta, 7:285, 1962). Another aliquot was pl~ced on a strong cation exchange resin (Amberllte CG-120). for separation of NE, E, NM, M and dopamine. Subsequent procedures and analysis of the amines were carried out by the methods descrl- bed by Haggendal (Scand. J. Clin. Lab. Invest., 14: 537, 1962). Although these present experiments are not completed, results obtained to date indicate an increase in the urinary excretion of E, M~ and VMA as a result of nicotine administration whereas no increases in the excretion of NE, NM or. dopamlne were observed. ' Similar experiments are being carried out on healthy human subjects substituting cigarette smoke inhalation for"nlcotine administration. Urine samples are being collected during three 30 min periods in which the subjects are smoking 3 cigarettes per 30 min period. Sufficient data to merit mentlon~has not yet been obtained. 0

EFFECT OF CIGAR AND PIPE SMOKING ON LIPID METABOLISM Samuel Bellet Division of Cardiology Philadelphia General Hospital Philadelphia, Pennsylvania In studies of the effect of smoking on lipidmetabolism, sub- jects showed greater free fatty acid (FFA) mobilization with ciga- rettes than cigars, which was reversed when cigars were inhaled and cigarettes not inhaled. In dogs, with the inhalation factor constant, there was no difference in FFA or triglyceride response to cigarette, cigar or pipe smoke; lipid effects of nicotine were similar to tobacco smoke. Catecholamine excretion during 4-hour periods of smoking was greater with cigarettes than cigars. In" dogs there was no difference in catecholamine output with cigarette, cigar or pipe smoke when.similarly administered by tracheal inhala- tion. The nicotine content of urine collected during 4-hour periods of smoking was greater with cigarettes than cigars or pipes. This was reversed when cigars and pipes were inhaled and cigarettes not inhaled. In dogs, with inhalation constant, there was no difference in nicotine excretion. Blood specific activity measurements after smoking radioactive tobacco showed greater absorption of pyrolysis products with cigarettes. The findings demonstrate that the greater lipid and catecholamine response to cigarette smoking is due to the tendency to inhale cigarettes with resultant greater nicotine absorption. This is substantiated by the higher level of nicotine excretion with cigarette smoking which is equalized by cigars and pipes when they are inhaled. In progress are studies of the effect of nicotinic acid on the lipid and catecholamine response to the different smoking forms and its effect in nicotine absorption (urinary excretion) during smoking. Also being studied is the effect of smoking and nicotine in the synthesis and metabolism of triglycerides and other lipid fractions in man and dog. In vitro tissue studies and in vivo perfusion experiments in dogs are being initiated in which the relationship of the lipid effect of smoking to cyclic AMP will be investigated.

NICOTINE AND NEUROGENIC VASCULAR TONE Ove A. Nedergaard, John A. Bevan (grantee) and Sandra Corbett Departments of Pharmacology and Pathology UCLA School of Medicine Los Angeles, Callfornla The action of nicotine on the response of vascular smooth muscle to sympathetic nerve stlmulatlon and on the restlngmuscle tone has been studied using the isolated recurrent cardiac nerve-pulmonary artery preparation of the rabbit. This i_~nvltro preparation was maintained in a buffered physiological salt solutlon(pH, 7.4) at 38° and aerated with a mixture of 95%02 and 5ZCO2. Electrical stlmulatlon of the recurrent cardiac nerve containing the post- gangllonlc sympathetic nerve supply, of the.pulmonary artery caused a very rapid contraction of the vessel followed by a return within -3 mlns to the original level of tone. Using stimuli of supra- maxlmal voltage, frequency 5/set, the effect of different concen- tratlons of nicotine on the contractile response to trains of 25, I00, and 200 stimuli res~ctlvel~ was determined. .After 30 mlns incubation, nicotine (10 V-3xl0"OM) reduced significantly (10-20Z) the ma~nltu~e of all contractions. Higher concentrations (3x10"v-10''M) however, potentiated the responses to nerve stlmu- lation by up to 60Z and occasionally.also caused a small increase in resting tone. The percentage potentiation caused by nicotine became larger as the train of stimuli was made longer. Inter- mediate concentrations had no effect on the magnitude of the responses. Since nicotine at pH 7.4 exists in both an ionized and unionized form, it is of interest to determhLe which of t~ese is mainly responslble for the pharmacologlcal action of nicotine. The effect of this alkalold was therefore compared with the quaternary compound, DMPP (dlmethylphenylplperazlnlum), which is fully ionized and possesses pharmacologically specific nicotinic properties. In contrast to nicotine, DMPP at concentrations of 10-7M and higher caused only a decrease.ln the contractions elicited by nerve stimulation. ~fter 30 mlns incubation the response was completely blocked by 10"~M of DMPP. This concentration also caused a smallIncrease in the resting tone of the artery. From these prellmlnary results it is speculated that the potentiating effect seen with nicotine is mainly due to the unionized part of the molecule, while the inhibitory effect observed with DMPP is related to its complete ionization. Experiments to further elucidate the site and mode of action of nicotine and related drugs on vascular smooth muscle is in progress and the results of these will be pre- sented and discussed.

EVALUATION OF THE EFFECTS OF CIGARETTE SMOKE IN THE INTACT GUINEA PIG S. Carson, R. Goldhamer and E. Clemente (Bernard L. Oser, grantee) Food and Drug Research Laboratories, Inc. Maspeth, New York A comparison of a number of cardiopulmonary parameters ~as been employed to evaluate the pathophysiologic consequences of acute and chronic inhalation of tobacco smoke by the intact guinea pig. The responses of the respiratory system, as the site of initial impingement, has been assessed in terms of the series of events which follow. Full body plethysmography using the technique of Mead and Amdur for acute exposures and that of Murphy for chronic or repeated exposures permit continuous evaluation of pulmonary function. Simultaneous recordings of right intraventricular pressure are obtained by permanent catheterization of the ventricle as described by~Popovic, with intraventricular and limb lead recordings. These are supplemented by the ~ecent addition of a gas-liquid chromatograph, for analysis of respiratorY gas concentrations in inspired and expired air and as a means of providing evidence of active compounds in trace concentrations of blood. Groups of guinea pigs were exposed to cigarette smoke for 5 days. a week in chambers using maximal tolerated doses, which would be leth~l if the exposure period were continued beyond this period. Simultaneous changes were observed in intraventricular pressure and in pulmonary compliance. The decrease in lung elasticity, seen after prolonged exposure to cigarette smoke, was accompanied by a marked increase in ventricular blood pressure. Findings in acute and chronic exposure regimens will be compared. Of particular interest are the differences in responsiveness observed between albino and non-albino guinea pigs.

THE EFFECTS OF SMOKING ON THE ~ART AND PERIPHERAL CIRCULATION IN MAN: MEASURED BY BLOOD PRESSURE, PULSE RATE, SKIN TE~[PERATURES AND ELECTRICAL IMPEDANCE PULSE VOLUME DETERMINATIONS Robert D. Allison Department of Physiology Lovelace Foundation Albuquerque, New Mexico Grace M. Roth Vascular Laboratory Lovelace Clinic Albuquerque, New Mexico Standard smoking tests were carried out on°60 male cigarette smokers ranging in age from 20 to 60 years. A non-occlusive four electrode impedance system was used to measure changes in pulse volume and blood flow to peripheral segments and the thorax. Simultaneous skin temperature, blood pressure and pulse rate were measured concomitantly. Such information has provided insight into the simultaneous effects of smoking on various portions of the body. The skin temperatures of the fingers and toes decreased more than the skin temperatures of the arms and legs. Likewise, the impedance pulse volume of the fingers and toes decreased more than the impedance pulse volume of the arm and leg segments. Smoking produced an increase in systolic and diastolic blood pressure and an increase in pulse rate. Blood flow in this study has been expressed as the product of pulse volume and heart rate, and despite an increase in heart rate, vasoconstriction dominated and resulted in decreased blood flow in peripheral segments. The thoracic pulses (thoracic impedance pulse changes synchronous with the cardiac cycle) as an index of pulmonary pulse volume changes indicated a reduction in pulmonary pulse volume during cigarette smoking. Heavy smokers demonstrated increased levels of carbon monoxide as established from infra-red analysis of alveolar gas.

MOTOR RESPONSES OF THE MICROCIRCUI..~i'ION FOLLOWING INHALATION EXPOSURE TO CIGARETTE SMOKE Paul A. Nicoll Department of Physiology Indiana University Medical Center Indianapolis, Indiana The motor response of both arterioles and venules when the animal is exposed to tobacco smoke have been investigated in the subcutaneous vascular bed of the wing membrane in unanesthetized bats. Commercial brand cigarettes obtained in the local market were smoked in an apparatus that gave one 35mi puff of two second duration once a minute. Each cigarette gave 7 to 9 puffs depending on the butt length. Animals were subjected to either a continuous environment of stQred diluted smoke or brief 5-15 seconds per minute exposures with each puff. The composition of the smoke varied depending on the procedure. Storage sharply reduces the particulate and so nicotine content of smoke. Continuous exposure to stored diluted smoke where the smoke concen- tration is 10% or less does not produce any significant response in the motor activity of the minute vessels. With higher smoke concentration some initial increase in motor activity is evident but this is soon reversed as inhibitory actions develop. Brief intermittent exposures to fresh cigarette smoke produce definite increase in motor action. Both arterioles, precapi]lary sphincters and venules showed increased strength of contraction and reduced resting length of the muscular elements. Inhibitory action does develop with repeated cigarette smoking at short intervals. Both the quantitative analysis of muscular response and the time aspects of the reaction have been followed with a new technical procedure. Using a closed circuit television set up the movements of the vessel walls due to muscular contraction may be detected by the use of photo-cells attached to the T.V. monitor screen. Magnitude of tonic action (reduced resting length) and the brief cyclic contractions are followed by this technique. The photocell readouts are recorded by a conventional polygraph and allow detailed analysis of duration and activity response.

OXYGEN DEBT ACCUMULATION IN S~K)KERS AND NON-SMOKERS Robert B. Chevalier Krannert Heart Research Institute Marion County General Hospital Indianapolis, Indiana Our data have shown that the oxygen debt accumulation of smokers is greater than that of non-smokers for a given exercise load. Additional work was done to account for this observation. Non- smokers were exercised and oxygen debts were calculated as the ratio of oxygen debt to total increased 02 uptake. The subjects then inhaled carbon monoxide until their carboxyhemoglobin levels were comparable to those of smokers. The subjects were then re-exercised and the 02 debt ration was found to increase under the effect of CO. The assumption was made that the CO in someway made the non-smokers have an exercise response more similar to a smoker. In view of these findings we have been undertaking some further observations as to the basic mechanisms involved. We have observed that there is a difference in the initial rise of the 02 uptake curve between smokers and.non-smokers This may be best demonstrated by the following lllustratlonl B represents the total increased ~0p uptake during work. C represents 02 debt. A represents The lag or "oxygen deficit". A large number of non-smokers in the past had a relation of A/C of approximately 0.75 to 0.80. In other words, most of the 02 debt went to repay the "oxygen deficit". On the other hand, smokers had an A/C ratio of approximately 0.50 -- a significant difference. In l0 non-smokers, the calculated A/C ratio was 0.85.
Page 390: 502077378
Oxygen Debt Accumulation In Smokers And Non-Smokers Page 2 This figure corresponded to the one obtained in a large group of non-smokers. After the inhalation of CO the A/C ratio in the same subjects fell to 0.50. In conjunction with this there was no significant change in area B. The 02 debt or area C did increase. The reason for this change has not been fully analyzed at this point. One speculation might be that the CO causes a need in increased 02 uptake that cannot be met aerobically. Therefore, the subject never reaches the steady state for the exercise and load that he does when no significant COHb is present. proposed Direction of Work for the Second Grant Year The methods of study of the subjects will be essentially as outlined in the grant proposal. No significant change in this technique is proposed. The aims of the second grant year will again be those outlined in the original proposal. In addition, we are anticipating studiesinvolving the 02 debt accumulation at higher work loads. In the past, thework loads selected have been sub-maximal. It is anticipated that studies will be undertaken that will involve maximal exercise in smokers and non-smokers with analysis of 02 debt. Such studies may add information as to the mechanisms of increased 02 debt accumulation in smokers.

THE STUDY OF THE EFFECTS OF NICOTINE ON THE HUMAN HEART BY ISOTOPE SCANNING AND BY REGIONAL MEASUREMENT OF CORONARY BLOOD FLOW Richard J. Bing (grantee) and Karel Rakusen Wayne State University School of Medicine Detroit, Michigan During the period sponsored by this grant, from July, 1964 until the present moment, we have been concerned with the effect of nicotine on the heart. Much of the time has been devoted to the technique, consisting in a study of the measurement of coronary blood flow using coincidence and isotope.scanning, and in the measurement of the capillary blood content of the heart. In the first method, we could establish the reproducibility of the technique, and show that variations in the counts on arterial blood have no influence on the results. We have furthermore demonstrated that we are measuring nutrient blood flow rather than total coronary blood flow, and that in the isolated perfused heart, the calculated flows check closely with those 6btalned by the direct Flick. Finally, we have now demonstrated that large changes in flow d~ocause alterations in the percentage myocardial extraction ratio. However, the quantltatlon for the measurement of coronary blood flow does not depend on measurements of percentage extraction ratio. We have found that smoking of cigarettes or the injection of nicotine has resulted in an increase in coronary blood flow in the normal, or a decline or no change.ln patients wlCh coronary artery disease. The behavior of nicotine is, therefore, similar to that of other coronary vasodilators. The second portion of our program dealt with a search for the effect of nicotine on alterations in coronary blood flow.. It was first our intent to measure this with scanning techniques. This course is being pursued, but the technical difficulties of producing 1-124 coupledto oleic acid and to albumin are considerable, and the process is. very expensive. Therefore, Dr. Rakusen in this laboratory has centered his attention to the effect of nicotine on regional capillary blood content in various portions of the heart under the influence of nicotine. His data have not demonstrated any significant changes in regional capillary blood content in the heart muscle following nicotine. However, nicotine resulted in an increase in capillary blood content of skeletal muscle.

THE EFFECT OF NICOTINE ON THE CANINE CARDIAC ACTION POTENTIAL Kalman Greenspan and Suzanne B. Knoebel Department of Medicine Indiana University School of Medicine Indianapolis, Indiana The effects of nicotine on canine myocardlum were studied, utilizing small strips of ventrlcular tissue and Purklnje fibers (false tendons)~ Continuously perfused with oxygenated Tyrode's solution containing nicotine base at a concentration varying from 2 - 20 micrograms per c.c., individual ventrlcular or Purklnje cells were impaled with glass mlcroelectrodes filled with 3 M. potassium chloride. Action potentials were elicited with bipolar stimulating electrodes, at rates varying from 60-120/minute and visualized on oscilloscopes which permitted simultaneous photographic recording. Characteristic changes in transmembrane action potential configuration were noted in both ventricular and Purklnje fibers, at intervals varying from I to hours after continuous exposure to the al~alold. These changes consisted, of attenuation or obliteration of the phase two plateau, phases two and three becoming confluent and resembling an exponential curve. This was observed with no alteration in the basic driving. rate, and was unattended by any significant change in the transmembrane resting potential. Such action potential alterations occurred more promptly with the higher concentrations of nicotine. Less commonly observed changes, following exposure to nicotine, included: reduced rate of rise of phase zero depolarization, with development of a 'step'; 2) loss of 'overshoot'; and.3) a decrease-of trans- membrane resting potential. The loss of overshoot was not necessarily related to the reduction in the resting potential. The development of spontaneous depolarization of PurkinJe fibers was also occasionally observed after nicotine administration. This was followed by a progressively more rapid rate of spontaneous depolarization (ca. 120/minute), and associated with the development of a marked 'step' or notch in the phase zero upstroke. The complex, thus altered, closely resembled that customarily recorded from A-V nodal cells. The physiologic basis for these action potential changes (i.e., acceleration of repolarization without a reduction in resting membrane potential) remain open to conjecture. It may be suggested,
Page 393: 502077382
The Effect of Nicotine on the Canine Cardiac Action Potential Page 2 however, that the aforementioned changes in repolarization may be" attributable to an enhancement of membrane permeability to potassium. The latter, in turn, may be ascribed to a direct effect of nicotine; or mediated via the release of endogenous acetylcholine, a character- istic effect of nicotine administration. The development of auto- maticity, on the other hand, cannot be explained in terms of enhanced membrane permeability to potassium. However, the occurrence of spontaneous depolarization may have resulted from endogenous eate- cholamine release, also a classically described effect of nicotine administration. ~ 0

SYMPATHOHIHETIC ACTION OF NICOTINE J. P. Long Department of Pharmacology State University of Iowa College of Medicine lowa City, Iowa There are a number of possible mechanisms by which nicotine may activate the sympathetic nerve terminals and release noreplnephrine. The major proposed mechanisms are: (1) stimulateganglia, (2) stlmulate "ramifying" ganglia, (3) stimulate the nerve terminals directly or, (4) in those organs with dual autonomic Innervatlons, activation of the parasympathetic nerves may indirectly release noreplnephrine. The. underlying mechanism of action for the sympathomlmetlc action of nlcot~ne has been the object of a major. part of our research. There is a wide species variation asfar as atrial responses to nicotine are concerned. The action of nicotine was evaluated for negative and positive chonotropic and-inotroplc action. ~These parameters of action were evaluated in atria from the rat~ guinea pig, cat, turtle, chicken,dog, frog, and rabbit. The decrease in force of atrial contraction was significant in all species except the frog. There was significant speeding in all species except the rat~ turtle~ and frog. There was significant increased force of atrial contraction in the rat, gulnea plg, cat, and rabbit. Therefore since the cat shows significant slowlng and speeding, as well as significant decrease and increase.in force of contraction to nicotine a considerable amount of work was done using these species. Inhibition of the parasympathetic nervous system with hemicholinium (HC-3) abolished both the positive and negative responses to nicotine. Both of these responses could again be observed after repeated washing over a 1-3 hour period. HC-3 did not inhibit the response to sympathetic nerve stimulation nor did it block the response to nicotine administered when the vagi were not stimulated. Similar mechanisms of action were found when evaluating the ability of nicotine to increase the vascular resistance of the mesenteric arteries of the cat. The innervation of the cat's iris definitely does not appear to be any interaction of the sympathetic and para- sympathetic nervous system. We are completing a study of the action using the cephalic vein of the" dog..In this preparation nicotine is very feeble in activity. Our work indicates that the sy~pathomimetic action of nicotine varies widely from species to species and there does not appear to be a singular or simple mechanism of action that initiates the sympathomimetic action.

STUDY OF THE EFFECT OF POLYCYCLIC HYDROCARBONS ON CHROMOSOMES E. Douglas Rees Department of Medicine University of Kentucky Lexington, Kentucky Some polycyclic hydrocarbons are powerful carcinogens, e.g. 3-methyl- cholanthrene, 7, 12-dimethylbenz(a)anthracene, and benzo(a)pyrene (one of the carcinogenic components found in tobacco tar). Oral administration of these compounds to rats induces cancer almost exclusively at a distant site - mammary gland. Since induction is markedly influenced by • carcinogen dose, age, sex and strain, this experimental cancer is an excellent tool for the study of carcinogenesis. Chromosome abnormalities are frequently noted in neoplasms, and it may be that changes in chromosomes are among the primary factors involved in the genesis of cancer. Accordingly, the effect of polycyclic hydrocarbons on the chromosomes of rat cells in being studied. Karyotypes of femur marrow cells from rats of strains with different susceptibility to induction of this cancer have been analysed. The very susceptible Holtzman rat has a karyotype similar to that of the relatively resistant Long-Evans rat, except the latter has a polymorphic pair of chrornoson~es (the $3 pair). ' Variations in karyotypes of cells from untreated rats of these strains have been defined and (for the Holtzman.rat) compared with changes occurring after carcinogen administration. Following carcinogen administration, a normal proportion of marrow cells remained .diploid but the range of number of chromosomes per cell was increased and aberrations in karyotypes were demonstrated. • Studies on rats of other strains have not been completed. Studies have also been started to demonstrate the presence or absence of the polycyclic .hydrocarbon carcinogens and their noncarcinogenic congeners on chromosomes.

INDUCTION OF INCREASED BENZPYRENE HYDROXYLASE ACTIVITY IN THE LUNG IN VIVO AND IN VITRO Lee W. Wattenberg (grantee) and J. Lionel Leong Department of Pathology University of Minnesota Medical School Minneapolis, Minnesota As part of a study aimed at determining methods of protecting the lung against the carcinogenic effects of polycyclic hydrocarbon carcinogens, the capacity of a number of heterocyclic compounds to induce an increase in benzpyrene (BP) hydroxylase activity of pulmonary tissue has been determined. A large series of compounds has been tested and of these the following, when given by oral administration, have been found to induce an increase in BPhydroxylase activity of the lung of the Sprague Dawley rat: several 5-memberedheterocyclic compounds with diaryl substitutions such as 2, 5 bis-(4-pyridyl)-l, 3, 4 thiadiazole, a number of phenothiazine derivatives, several flavones, 2.-phenyl benzothiazole, dibenzothiophene, and 5, 6-dimethy]- 2-(3-pyridyl) benzimidazole. Data pertaining to the effects-of various structural alterations of inducer molecules on their inducing capacity have been obtained. Induction can be carried out by the intratracheal route but results in no greater activity than with oral administration. A]HeJ and C3H/HeJ strain mice show increased BP hydroxylase activity in their lungs in response to oral administration of inducers effective in the rat. The untreated Syrian hamster has a lower pulmonary BP hydroxylase activity than the rat or mouse and is relatively unresponsive to most inducers. However, a " high activity can be induced in this species by beta,naph~hoflavone. In addition to in vivo induction, it has been possible to induce an increased BP hydroxylase activity in small pieces of rat lung cultured in vitro.

TIlE ROLE OF AI.PHA-EMITTING ISOTOPES IN TIlE EFFECTS OF CIGARETTE SMOKING Robert L. Bogner Nuclear Science & Engineering Corporation Pittsburgh, Pennsylvania This study is designed to investigate the significance of polonium-210 and related radionuc]ides as health hazards associated with smoking. Urinary excretion rates of Po-210 by smokers and non-smokers as well as abstaining smokers are being evaluated. Results have confirmed that smokers excrete substantially more Po-210 in the urine than non-smokers. The average urinary daily excretion of 0.14 la~ac Po-210 by a heavy smoker was approximately five times greater than the corresponding urinary excretion of 0. 027 ~ c per day by a non-smoker on an identical diet. The urinary excretion of Po-210 by the heavy smoker did not show a significant decrease following abstinence from smoking for over 40 days; apparently an appreciably bod.y burden of Po-210 developed in the heavy smoker over his twenty year smoking history. Selected dietary constituents such as beer and cola drinks have been identified which markedly influence the Po-210 excretion in the urine and strongly affect the values obtained on spot urine samples. The content of polonium-210 and its precursors, radium-226 and lead-210 will be determined in autopsy and surgical specimens of human tissues, particularly lung parenchym.a, bronchial tree, teeth, bone and various soft tissues, of smokers and non-smokers, of individuals in different geographical areas within the United States and different parts of the world, and of urban and rural inhabitants. Methodology has been refined for the analysis of the very low levels of 1'o-210 in lung tissues. It is now evident that natural 1'o-210 can be detected in dog lung specimens as well as in other soft tissues of the body. Human lung tissue obtained at autopsy is being analyzed to determine the influence that sampling techniques and sample handling procedures (freezing, fixatives, etc.) may be expected to have on the analytical results. After it has been demonstrated that specific portions of human lung should be procured and treated according to a standard technique, collection of autopsy and surgical samples will be instituted on a much more compre- hensive world-wide scale and appropriate smoking, occupational, and residence histories will be accumulated. Results of human tissue analyses will be related insofar as possible to the naturally-occurring levels of the radionuclidcs in tobacco and smoke, atmosphere, water, and diet. Arrangements have been made to obtai.n 50207 7389

Similar samples have been collected by NSEC at various sites in the greater metropolitan Pittsburgh area. Analyses of over eighty samples from near Pittsburgh reveal that Po-210 concentration range from 1 x 10-5 to 2 x 10-4 ~tac per ft3 with some suggestion at present that collections near power stations that burn fossil fuel show Po-210 levels near the upper limits. Analysis of samples from the national network so far indicate that reasonably similar Po-210 levels may exist elsewhere. World-wide samples of cigarette tobacco have been analyzed for Po-210 and except for a few apparent exceptions (e. g. India and Luxembourg), the Po-210 content closely resembles the content of American cigarette tobaccos. Attempts will be made to trace the cause for low Po-210 levels in the exceptions. All samples analyzed for Po-210 have been set aside after plating. After sufficient grow-in time, they can then be plated for Pb-210. Following the Pb-210 determination, the samples can then be run for Ra-226. This sequence provides a minimum of analytical problems. 50207 7390

EFFECTS OF PHARMACOLOGICAL AND PSYCHOLOGICAL VARIABLES ON SMOKING BEHAVIOR IN NAN WITH SPECIAL EMPHASIS ON THE ROLE OF NICOTINE Benedict R. Lucchesl, Charles R. Schuster (grantees), and GraceS. Emley Department of Pharmacology University of Michigan Medical School Ann Arbor, Michigan Nicotine has been considered by some to be the decisive factor in the effects of tobacco in those "addicted" to smoking where the pharmacological actions of nicotine play a greater role than its local effects. Previous studies by Johnston (1942) and EJrup (1963) have attempted to assess the role of nicotine in the smoking habits of man. Their results suggest that parenteral administration of nico- tine will alter an individual's smoking frequency. The present investigation s~udled this relationship ~n human volunteers who were unaware of the true nature of the study or the drug being administered. During the past year I0 male and 2 female volunteers between 21 and 26 years of age participated in this.study.. The subjects were confined to ~ soundproof booth for a duration of 6 hourson each of 15 consecutive experimental sessions. Sessions for nico- tine or normal saline administration were randomly selected. Solutions were given by the intravenous route and controlled by a peristaltic roller-pump with variable speed so as to adjust the drug dosage. Throughout each session the.subjects were assigned a definite schedule of behavioral testing and were permitted to smoke ad libltum. Blood pressure, heart rate and respiration were continuously monitored. Smoking behavior was not altered slgniflcantlywhen nicotine was administered in a dose of I mg for 30 minutes every hou~ or 2 mg per hour continuously for 6 hours..In five subjects, receiving 4 mg/hr, there was a significant decrease in the total number of cigarettes consumed. The systolic blood pressure and heart rate recordings indicate that the physiological alterations in these~ parameters produced by smoking can be reproduced by parenteral nicotine. Specificity of the effect of nicotine on smoking behavior is suggested by the failure of this drug to produce any changes in the behavioral ~arameters neasure'd.

"THE EFFECTS OF NICOTINE ON TIMING BEHAVIORIN THE RAT; I. EFFECTS ON ACQUISITION OF THE BEHAVIOR; II. PERFORMANCE OF THE BEHAVIOR FOLLOWING WITHDRAWAL OF THE NICOTINE" Irving Geller Department of Pharmacology and Toxicology Southwest Foundation for Research and Education San Antonlo, Texas Hungry rats will be trained to time precisely by rewarding with food. Lever responses will be spaced 20 to 22 seconds apart, During the training period, one-half of the rats will be given chronic administrations of physiological salt solution. After the temporal discrimination is established in all animals, the nicotine and saline injections will be discontinued and the animals will be subjected to the same behavioral procedure. The purpose of the study is to determine: (a.) whether chronic administrations of .. nicotine will influence the rate of acquisition of the temporal discrimina- tion; and (b.) the effect of abrupt wlthdrawal of nicotine on the performance of the discrimination. Another project has yielded preliminary results on the effects of nicotine discrimination in rats. In this experiment tone stimuli are randomly presented to hungry ratsin Skinner Boxes. If a light is on above the lever during, the tone stimulus, a lever response. produces a food reward. If the light is off above the lever.durlng the tone stimulus, a response produces a 30-second blackout period. For a second group of rats, light stimuli above the lever are ran- domly presented to hungry rats. If the tone is present during the light stimulus, a lever response is rewarded with food. If the tone is absent during the light stimulus period, a lever response is punished with a 30-second blackout period. Records are kept of correct and incorrect responses during the experlmental-sesslon. Preliminary results show that most doses of nicotine increase both correct and incorrect responses. However, .some doses of nicotine appear to decrease incorrect responses. Thlsmlght con- ceivably be interpreted as a tranquilizing effect of nicotine. 50207 7399

BEHAVIORAL EFFECTS OF NICOTINE IN SQUIRREL MONKEYS T. R. A. Davis, H. J. Bronsteln, C. J. Kensler (grantee) Arthur D. Little, Inc. Cambridge, Massachusetts The effect of nicotine intraperltoneally was studied in three behavioral schedules: a multiple fixed Interval/flxed ratio schedule, a Sidman avoidance schedule and a vertical acti- vity schedule. The vertical activity schedule involves physical work by requiring the animal to operate two levers, one at the. bottom and one at the top of a two meter pole which must be tra- versed to operate the levers for positive reinforcement. Know- ledge of the dlstancetraversed between levers, animalwelght and time of traverse allows computation of work done. Of five doses examined in the multiple fixed Interval/flxed ratio sched- ule, nicotine produced an increasedrespondlng rate at 0.15mg/kg during fixed interval periods but had no effect on fixed ratio. In the avoidance schedule, nicotine produced an increased res- ponding rate at doses of 0.05, 0.15 and 0.45 mg/kg. In the verti- cal activity schedule nicotine produced no.changes except a decrement of performance at 0.45 mg/kg both for work done and for the rate at which work was performed. It is concluded that nicotine at effective doses produces an increased responding rate in those schedules in which physical work is not a primary component. A learning schedule, a steadiness schedule and a nega- tive reinforcement physical work schedule are at various stages of completion and is proposed that future objectives include comparison with other compounds whlch have similar effects. In anticipation of this program change comparison of nicotine with d-Amphetamine is presently underway and preliminary results indicate that nicotine effects are similar to those of d-Amphetamlne.

PROGRESS .REPORT OF THE ACTION OF NICOTINE AND NICOTINE DERIVATIVES ON LEARNING AND RETENTION. Danlel Borer Department of Pharmacology University of Sassarl Sassari, Sardinia An earller report (1963-1965) indicated that nicotine induced a central stimulation and has a facilitating effect on the acqui- sition of a conditioned avoidance response in rats. Using various recently developed automatic devices, the effect of drugs on different types of conditioning, vlsual discrimination and maze learnlng was compared.ln rats and mice. The action of nicotine on maze learnlng was similar to that exerted on avoidance learnlng. Furthermore, avoidance conditioning of inbred strains of mice was used to analyze the effects exerted by genetic factors. This indicated that the action of nicotine is strain dependent and that the degree of facilltatlon is generallyhlgherIn the strain characterized by a low performance .level. ~ .- Comparison was made between the effect bf nicotine, nicotine derivatives, scopolamlne, mecamylamlne and other chollnerglc drugs. Nicotine and scopolamlne were found to exert two different patterns of facilitatlng effect on avoidance conditioning of.nalve animals. Mecamylamine impaired acquisition Of avoidance condltlonand and antagonized the action of atropine. Striking dlffer~nces were observed when a drug was administered to naive and previously treated animals. In a study concerned with the effect of nicotine on the-rat in the running wheel, opposite effects were observed in relation to the nyctemeral rhythm. The same dose of nicotine had a stimu- lating effect when injected during the daily rest. period and a sedative effect during the night period, usually characterized, by maximal spontaneous activity. The results are discussed in relation to thevarlous functions exerted at different levels by cholinergic mediators on.the central nervous system and to the existence of a dual mechanls~ of learning and retention. • 5020";

RESEARCH ON BEHAVIORAL ASPECTS OF SMOKING Dorothy F. Dunn University of Illinois • Department of. Health Science Urbana, Illlnols This preliminary report, concerns-the smoking habits of fresh- man students on the University of 111inols Urbana campus. Data for 102 variables were obtained through a self-admlnlstered precoded questionnaire from enrolled students and from a transfer of infor- matlon from the Student Data System magnetic tape. Of 3,567 students 2 in 5 smoked regularly and 98.0Z were resl- dents of Illlnols. Seven in I0 were men, and there were over 2 in 5 of the men and I in 3 of the women who smoked. A total of 95.2Z began to smoke before age eighteen. Of the I in 5 from farms and rural nonfarmareas i in 4 smokedand-for Chicago thls-was almost 1 in 2. Showing a relatlonshlp with mobillty of residence were the education of the father, occupation of head of household, and the education and smoking habits of .the mother. There. were I in 5 of the valedictorians and l.in 3 o~.thesalutatorlans of high.schools who smoked. For students in the James Scholars honors program approximately 1 in 3 smoked; and for those receiving full financial support entirely from scholarships this was approximately 1 in 5. For students with spending money of less than $5,~3 in 10 smoked and students with over $10, approximately I in 2 smoked. Of stu- dents who participated over 5 hours a week in organized campusactl- vltles, 1 in 3 smoked, and of students who had not held membership in any organization during the last 12 months almost 1 in 2 Smoked. If a student who smoked had a roommate who also smoked, he was more llkely to have increased the number of.clgarettes he was smoking during the past 12 months than the student with a roommate who did not smoke. Only sllght differences of opinion in student nonsmokers and in those who smoked regularly regarding parental attitudes were evident: I in 5 strongly disapproved, 2 in 5 disapproved, and less than 1 in 20 reported that their parents approved of smoking. The more cigarettes a student smoked a day the more times he had attempted to stop smoking. Of 4 in 5 who smoked cigarettes with filters, I in 4 smoked more than one pack a day, and i in 6 consumed all the tobacco portion of a cigarette with a filter. Almost 9 in I0 believed that a cigarette smoker has a greater chance of developing lung cancer than the nonsmoher and the same number disagreed with the statement that cigarette sales should be banned on campus. There were ~ in 5 who believed that freshmen students in college are adequately informed regarding potential dangers of smoking cigarettes. NOT IN ATTENDANCE 50207

PHYSIOLOGICAL DISPOSITION AND BIOTRANSFORMATION OF LABELLED NICOTINE C. G. SchmlterlSw (grantee), E. Hansson, G. Anderson, L. E. Appelgren and P. C. Hoffmann Department of Pharmacology Royal Veterinary College Stockholm, Sweden The distribution of cl4-1abelled nicotine in mice and cats has been studied using Ullberg~s autoradlographlc method. Whole-body autoradiography, autoradlography of. the brain and the adrenal, and mlcroautoradiography of the superlor, cervlcal ganglion have been employed. These methods visualize the distribution of the radioactive isotope.present in nicotine and/or its metabolltes. Nicotine and its metabolltes very rapidly accumulate in the brain but obviously leave the brain fairly soon. The accumulation of nicotine and/or its metabolltes in other target organs than the brain, such as adrenal medulla, suPerior cervical ganglion, gastric mucosa, and blood vessel walls is described. Microautoradlography of the superior cervical ganglion reveals that only part of the ganglion cells take up radioactivity following administration of cl4-nlcotine. Paper chromatography of chloroform extract from. the brain, liver, kidney and stomach after intravenous injection of nicotine-methyl-Cl4 indicated that nicotine ~as rapidly metabolized to continue. The latter compound was isolated and identified by physical and chemical methods. No other radioactive compound in addition to C1402 was observed by-the methods used in this study. The metabolism of nicotine has also been investigated in tissue slices of various organs of the mouse using cl4-1abelled nicotine and thin-layer chromatography. Of those tissues studied, the liver, the kidney, and the lung were found to metabolize nicotine, while the brain, diaphragm, spleen, stomach, small intestine, and adrenal glands did not. The metabolic products identified were continine, y-(3-pyridyl)-y-oxo-N-methyl- butyramide, hydroxycotinine, and C1402. Two unidentified products have been separated chromatographically. Further work concerning the distribution of C14- and H3-1abelled nicotine in the brain at the cellular and subcellular level is in progress.

STUDIES ON 14C LABELED NICOTINE METABOLITES Herbert McKennis, Jr. Department of Pharmacology Medical. College of Virginia Richmond, Virginia During the mammalian metabolism of (-)-nicotine, the alkalold undergoes a number of changes, including an oxidative deterioration of the pyrrolidine ring. Studies with both isotopic and non-lsotoplc nicotine have proceeded to the point where general schemes of the metabolic pathways have been clearly delineated. In extending these studies quantitatively to the cellular and organ level,need for ~)-nicotine and its metabolites wlth.a high specific activity of ~C has developed. .. The objectives of this study have been met in principle by a series of synthetic steps starting with nicotlnlc_acld. For the radioactive steps, the highest specific activity 14C commerclally available was employed. This provided a labelingin which approxl- mately 80 per cent of the carbon atoms adjacent to the pyrldlne ring are in the form of 14C. . Nicotinic acid was esterlfled, and the resultant ethyl nlcotlnate was condensed with ethyl succinate to obtain ethyl nicotinylsuccinate, which was hydrolyzed and decarboxylated.to obtain 7-(3-pyridyl)-v- oxobutyric acid (I). A reductive methylamination o£ I provided (+,-)-y-(3-pyrldyl)-y-methylaminobutyric acid (II). II was converted to a (+,-) benzoyl derivative [(+,-)-III] and resolved with L-(-)- ephedrine. (-)-III was hydrolyzed and lactamlzed to obtain (-)- 25 contlnine, characterized as a monoplcrate, [a]3461 +27,5°. The synthetic routes under investigation in this study haveprovided totally synthetic (~)-nlcotine with the required label. In addition, these and related synthetic routes provide (+)=nicotine and a. number of nicotine metabolltes: y-(3-pyridyl)-y-methylamlnobutyric acid, ¥-(3-pyrldyl)-¥-hydroxybutyric acid, ¥-(3-pyrldyl)-¥-oxobutyrlc acid, cotlnlne, demethylcotinlne, and y-(3-pyrldyl)-¥-oxo-N- methylbutyramide. The possibilities of detailed study of many facets of the metabolism of nicotine can be increased through use of these and related synthetic routes, which make possible the utilization of small, so-called physiological, quantities of nicotine and its metabolltes in tracer studies. Preliminary biological studies done in collaboration with the Department of Pharmacology, Royal Veterinary College, indicate a high level of excretion of .,-(3-pyridyl)-..,-oxobutyric acid-~1-14C after intravenous administration to the mouse. 5020?

SOME STRUCTURAL ASPECTS OF NICOTINE PHARMACOLOGY Charles H. Jarboe Department of Pharmacology University of Loulsville School of Medicine Loulsville, Kentucky A program to synthesize several types of nicotine derivatives has begun. Parallel studies on selected aspects of their biological activity are in progress. Inltial emphasis is on the production of compounds selectlvely quaternlzed at the pyrrolldlne nitrogen with alkyl halides. Nicotine has been reacted with methyl iodide and benzyl chloride to yield complex mixtures of products. The desired compounds were i~olated by the use of Column chromatography and plcrate formation. Structural assignments were made on the basis of elemental analysis, infrared, ultravlolet and nuclear magnetic resonance spectroscopy..These are the first of a group of compounds selected to demonstrate the effects of structural change on nervous system activity of the nicotine structure. Pharmacologic assay of these nicotine derivatives was performed using Ran.__~a piplens rectus abdomlnus muscle and a gulneaplg ileum preparation. The former measures activity at voluntary muscle end synapses and the latter activity at ganglla. All of these measurements are relative to nicotine as a standard agonlst. The bioassay work on both compounds is still in progress. The data presently available indicate quaternlzatlon with both halldes to effect receptor affinity and intrinsic activity. This effect appears to be greater for the benzyl derivative, indicating the possible existence of both electrlcal and sterlc factors in the reaction between biological receptor sites and these substances. This is being pursued further with the synthesis andevaluation. of other model compounds. No evidence has been obtained which would indicate either of the two compounds now under study to have blocking properties. $0~0~

QUANTITATIVE METHODS FOR THE DETERMINATION OF THE DISTRIBUTION OF NICOTINE AND ITS CONGENERS IN BIOLOGICAL SYSTEMS Herbert McKennls, Jr. Department of Pharmacology Medical College of Virginia Richmond, Virginia With increased interest in the quantitative determination of nicotine, its metabolites, and congeners in biological fluids and. cellular extracts, needs havedeveloped for methods that are accurate and rapid when small and limited amounts of biological material are at hand. Although much has been reported on gas-llquld chromatographic methods for the determination of nlcotlne, most methods appear not to provide the sensitivity desirable for many types ofmammallan studies. One approach to a solution to this problem under study hasbeen to provide, by chemical-alteration, nicotine-and-lts congeners ...... with groups known to have strong electron affinities and thus extend gas-liquid chromatographic methods to the ultimate capabilities of electron-capture detectors, which have usable- sensitivities under proper conditions several-thousand times as great as flame-ionlzatlon detectors. The two methods chosen for initial study provide for the introduction of a double bond in conjugation with the pyrldlne ring (I), and the introduction of a maximum usable number of fluorine atoms (2) The procedures which, in principle, have already shown success are now being refined for possible biological application. 3-Acetylpyridine (Aldrich Chemical Co.), a reported bacterial metabollte of nicotine and a product from fermentation of nicotine in cigar tobacco, has been subjected to gas-llquld chromatography on a column (Oronite polybutene 128, 2% on AnakromABS, 3'x 118") at 110°. The signal (retention time of 60 seconds referred to benzene as one) obtained under these conditions with an electron- capture detector gives usable information with known solutions containing as little as 2 x 10-12 grams of material. The electron- capture detector appears also to be suitable for determining esters of y-(3-pyridyl)-y-oxobutyric acid, a mammalian metabollte of nicotine, and nicotine that has been chemically converted to a ~-perfluoro- acylmetanicotine. Conditions for the application of these and related procedures to biological material are under study. 50207

ELECTROENCEPHALOGKAPHIC CHANCES IN MAN FOLLOWING SHOKING AND NICOTINE Henry B. Murphree and Carl C. Pfelffer Bureau of Research in Neurology and Psychiatry New Jersey Neuropsychlatrlc Institute Princeton, New Jersey Quantitative electroencephalography provides reliable and sensitive methods for assay of drug effects upon the central nervous system. These methods have beenapplied to study many different kinds of drugs, including ehtanol and other substances with "antlanxiety" effect (Arch. Gen. Psychiat. I~0:446, 1964) and In~ludlng stimulants or "antidepressant" compounds (Ann. N.Y. Acad. Scl. I0__~7:1045, 1963). This provides a set of r.eference standards by which many factors .affectlng. the central nervous system can be. gauged. The-studies reported here were conducted to determine the effects of smoking and nicotine according to these standards. The subjects .were smokers and non-smokers of both sexes, ages 21-43. Plain and mentholated cigarettes with and ~ithout filters were studied; as were pipes and cigars. Trials included pufflng,~ unllghted;in-- haling, unlighted; puffing, lighted; and inhaling, lighted. All trials were with subjects shplne, eyes closed, in a partially darkened, sound attenuated room. EEGs ~rom left or both left and right occipital areas were analyzed by the Drohockl method (Int. Rev. Neuroblol. ~:265, 1965) and recorded on magnetic tape for time series and frequency analysis by means of a digital computer (Int. J. Neuropharmacol.. ~:97, 1964). Results so far suggest that the most prominent effects.of smoking, those after inhaling, occur very rapidly, in less than a chest-to-head circulation time, so that reflex mechanisms are probably involved.

THE EFFECTS-OF SMOKING AND NICOTINE UPON CEREBROVASCUI~R ACTIVITY Sheldon H. Steiner Department of Medicine Northwestern University School of Medicine Chicago, Illinois ~he purpose of this research was to determine the effehts of nicotine and smoking upon cerebrovascular reactivity. The method proposed to measure changes in cerebra] blood flow as that of determining the cerebral uptake fraction of 4 lodo]31antipyrine after a slug intravenous injection. The cerebra] uptake of indicator in the absence of redistribution was caIculated by extrapolation to initial delivery. The first goal of this investigation was to determine the validity and reproducability of these extrapolations under controlled conditions in a precisely calibrated model. An eight-compartment recirculating flow model was connected in series to a ]50 m]. compartment which served"as a cardiac mixing chan~er. All other compartments were in parallel. Total volume of the system was 14 I, and compartment volumes ~anged from 0.5 to 3 L. Compartment flow rates were varied from I20 to 2140 ml/min. Total system flow was maintained at 5.]2 L/min by a calibrated f]owmeter. ~nf]ow to each chan6er was measured without disturbing the system. Each compartment was observed in turn by a collimated scintillation probe which led to a linear ratemeter with a l-second time constant. Rates of change of indicator (Cs137) input and washout were recorded. IRe difference between these mDno-exponential functions was extrapolated to TO semilogarithmica]ly. Counts per minute at T0 were converted to a~raction of the injected tracer by counting a known amount of injectate using identical volume and geometry. Systemic fIow was ca]cu]ated by the Stewart-HamiIton indicator dilution method. Three methods were used to calculate compartment flow: (]) Extrapolation to T0 of indicator input and net rate of redistribution; (2) Extrapolation to T0 of change in organ indicator content in the absence of recirculation; and (3) Using the "t½" of change in organ indicator content in the absence of recircu]ation. ]'he T0 of the injected fraction (Methods ] and 2) was multiplied by calculated systemic flow to determine compartment flow. Comparing actual and calculated flows gave the following mean percent errors and standard deviations: B~thod I (-0.]5 i 6.86); Method 2 (-0.65 i 11.]I); Method 3 (-2.07 i ]1.69). ]'he correlation coefficient for each method was NOT IN ATTENDANCE

THE ROLE OF NICOTINE AND RELATED SUBSTANCES IN THE GENESIS OF PROLONGED GANGLIONIC FACILITATION Gerard L. Gebber Department of Pharmacology M~chlgan State University East Lansing, Michigan High frequency pregangllonlc stlmulatlon-and repeatedexposure to nlcotlnlc-llke agents, produce a state of prolonged synaptlc facilltatlon in autonomic ganglla. The facilltatlon is char- acterized by enhanced gangllonlc discharges to injected acetylchollne as well as to other exogenously admlnlstered chollnerglc agents. Since the effect of repetitive pregangllonlc stlmulatlon and injected nicotine may be r~tmlcked by chronic smoklng~ It-seems reasonable to investigate the factors re~ sponslble for the genesis of prolonged gangllonlc facilltatlon. It is evident from the works of several groups that post-activation facilitation (post-tetanic potentiation), in autonomic ganglia, cannot be explained solely be each or a combination of the following: (1) changes in the presynaptic terminals which, in ..:tgrn,_.m~ght influence transmitter release;-.(2) sustained~ curare- sensitive depolarlzatlon of the gangllon cell; (3) sustained atroplne-sensltive depolarization of ~he gang!.ion cell. _A proposal has been f0~lated which suggests .that the genesis of post-activatlon facilltation may be associated with changes in the afterpotentlals whichcharacteristica1Iyfdlldwdischarge of the ganglion cell. Such changes presumably would beInduced by a ~itherto unsuspectedsction of-thesynaptic med#ator"and of exogenously administered nicotlnic-like substances.

Department of Pharmacology University of Michigan School of Medicine Ann Arbor, Michigan Carlson This investigation is primarily concerned with the pathophyslologlcal effects of~chronic intravenous administration of doses of nicotine comparable to those obtained during smoking. A modlflcatlon of the strain gage force transducer developed by Jacoby et al. (J. Appl. Physlol. 18:658, 1963) was sutured on the left ventrlcle, the perltoneal surface of the diaphragm and the pylorlc antrum of the Rhesus monkey. Independent monitoring Of !ongltudlnal and clrcular muscle activity of the antrum can be achieved by this method. A silastlc catheter was placed in the ~Ight aurlcle via the external Jugular vein for drug administration. EKG and blpolar EEG electrodes were also" Implanted. These anlmals .are presently for programmed drug administration. In preliminary studies partially restrained unanesthetlzed dogs (prepared as described .above) received doses of nicotine (25-200~g/kg) on an accumulative basis, at 15 minute intervals. Minimal cardiac slowing was observed following 25 ~g/kg. The accumulatlve dose 50-100 ~g/kgproduced an increase. in myocardial contractile force and a bradycardla which gradually returned toward control levels. No significant EZGalteratlons were noted. Resplratoryrate and depth were increased. An Inltlal bradycardla followed by a tachycardla was produced by the 200 ~g/kg dose. Myocardlal contractile force wasenhanced. Contractions Of t~e antrum were inltlallydepressed. This depression was closely followed by restlessness, retching and licklng.but never emesls. The retching was associated wlthlarge~contractlons, of the antrum and diaphragm. This phase of antral hyperactivity was followed by a second period of depresslon and gradual recovery. When 200 ~g/kg was given as the inltlal dose muscle tremors, salivation, defecation and urination were produced. This was never observed when the 200 ~g/kg dose was administered on an accumulative basis. receiving nicotine on a chronic baslsutillzlng ame~h0d ....... 50207 ?q12

EFFECTS OF NICOTINE ON ISOLATED ~SCLE George B. Weiss Department of Pharmacology Medical College of Virginia Richmond, Virginia A number of approaches have been utilized to obtain informatlon~ concerning the mechanism of action of nicotine in isolated muscle systems. In frog sartorlus muscle, an increased Ca45. uptake is induced by. nicotine at doses much lower than those which elicit contracture. Both the contracture and lucreasedCa45 uptake are inhibited by In- creased K iOn concentrat.lon or decreased pH. Lowering the pHfrom 8.4 to 7.4 inhibits the contracture, the increased Ca45 uptake and the uptake of C14-nicotlne. Lowered pH apparently decreases the access of nicotine to a cellular site by diminishing the proportion of unionized nicotine available. Increased K ion does not inhibit C14-nicotlne uptake or Ca45 efflux induced by nicotine, and may therefore block nicotine contracture by dlrectly inhibiting the increased uptake of calclum ion normally associated with the action of nicotine. The nicotine contracture occurs even .in zero Ca.Ringer's solutlon containing 4mMEDTA. However,..the increased Ca~5 efflux obtained under these conditions Indicates.that nicotine can release bound calcium from cellular sites. Experiments using calcium-free solutlons indicate that part of the calclum speclflcally released by nicotine is the self-exchangeable calclum, The uptake of C14-nlcotlne is quite rapid andequillbrlum is attained in approximately ten minutes. This uptake is inhibited by lowered pH (decreasing entry rate) or lowered temperature. The monoamlne oxidase inhibitor Nialamlde also appears to decrease uptake of C14-nlcotine. In longitudinal smooth muscle from gulneaplg ileum, nicotine causes a transient contracture, an increase in Ca45 uptake and a decrease in total calclum content. Various approaches indicate that nicotine may also act to release membrane-bound calclum in this tissue. The extracellular space has been measured and the uptake of C14- labeled histamine and serotonln has been dellneated in order to compare the movements of these agents with those of nicotine. 50207 7~113

EFFECTS OF SHOKING UPON UTERINE CONTKACTILITY AND PLACENTA IN HUMAN PREGNANCY Charles R. Echt and Richard W. Stander Department of Obstetrics and Gynecology Indiana University School of Medicine Indianapolis, Indiana It is a well known fact that pregnant patients who smoke seem to have infants of smaller size than non-smoking patients. The purpose of our investigation, which began in July of 1965, is to determine, if possible, the etiology, of low weight infants in smoking mothers. In order to do this in v~tro and in vivo studies of uterine contractility are being done in smoking and non-smoking patients and these results are being correlated with placental function in pregnancy. The in vitro studies are being done upon the uterine musculature in pregnant patients who come to cesarean section. Myometrial strips preliminarily have shown increased activity when bathed in nicotine. In vivo studies are being done by external toco- graphic measures. The placental function study, which is presently being used in an effort to predict fetal outcome, is that of urinary Estriol determination. These determinations are being done on 24-hour urines in the first, second, and third trimesters of pregnancy in smoking and non-smoking patients. The uterine contractility in vivo studies are being done simultaneously with the urinary Estriol determinations. At the writing of this abstract, the results were very preliminary, as the study had just been begun. 50207 7~17

Kirschbaum Department of Obstetrics and Gynecology UCLA School of Medicine Los Angeles, California The proposed studies are aimed at investigating the effects of smoking by the mother on utero-placental and fetal circulations and metabolism in animal and human subjects. The animals to be used are pregnant sheep, monkeys and cats. Maternal and fetal arterial pressures, uterine and umbilical blood flows, maternal and fetal P02, pH, pCO2 and carboxy- hemoglobin will be measured in control, smoking and recovery periods. In a series of chronic experiments on pregnant sheep, maternal and fetal circulatory and respiratory parameters will be measured in the conscious state in control, smoking and recovery periods. In the smoking period, the sheep will be placed in a specially constructed chamber with the atmosphere saturated with cigarette smoke. The human investigation will be carried out on pregnant women in various periods of gestation. The effects of smoking on maternal hem~dynamics will be recorded. The time for initiation of breathing by the newborn will be recorded in the smoking group and compared to that of nonsmokers. Fetal blood composi- tion will be analysed in infants born to a group of smokers and compared to that of nonsmokers. NOT IN ATTENDANCE 50207

NICOTINE ABSORPTION IN RATS DURING PREGNANCY: A BRIEF PROGRESS REPORT R. F. Becker (grantee) and J. E. King Laboratory of Perlnatal Studies Duke University Medical Center Durham, North Carolina Pregnant rats injected twice daily with 0.5 to 1.0 mg nicotine per kg exhibited no changes except for the very mild convulsive episodes following each injection. They did not develop a tolerance for nicotine over this 21 day period. The doses were in range of those purported to be absorbed by the heavy smoker. Gestation times, birth weights, survival and developmental status of the young differed no whit from similar parameters in untreated, or saline-injected controls~. With slightly higher doses twice daily (3-5 mg/kg), pregnant rats consumed less food, wasted more by spillage, and gained far less weight than control mothers. They delivered young 2-4 days beyond term; the young were underweight and fetal in appearance. Stillbirth and infant mortality rates were higher than in controls, but not as great as in young delivered 2-4 days post-term from mothers receiving Antuitrin-S to purposely delay delivery. There were no abortions and no premature deliveries. Surviving young had no difficulty establishing air breathing. They were pink and healthy, though immature in appearance. Along with decreased birth weight went a shorter transverse skull diameter; shorter vibrissae; less ossification in radius and ulnar, than in term control neonates. They often lacked nails. The placentae, while small, were firmly attached and, apparently, functional, despite the delayed delivery. In contrast, post-term infants of the Antuitrin-S group were heavier than term controls; had wider transverse skull diameters; longer vibrissae and nails; and a greater degree of ossification in the long bones. Placentae were infarcted and very tenuously attached. Neonates were cyanotic and in respiratory distress. Few survived. Many were hump-backed and club-footed, whereas no teratology appeared among the nicotinized group. If nicotine were fed in the drinking water even at high dose levels, maternal convulsive episodes were prevented. A more uniform drug titer could be protracted over 24 hours. Imbibition at intervals more nearly resembled a smoking situation.

Nicotine Absorption In Rats During Pregnancy: A Brief Progress Report Page 2 With daily intake of as little as 2 mg/kg/day, food consumption was reduced 5% and water consumption 34%. There was no maternal weight loss during pregnancy; young were born at term With birth weights equal to those of control neonates. With intakes of i0 mg/kg/day, food consumption dropped to 45% and water consumption to 60%; mothers lost weight during pregnancy; delivery was again delayed; young were underweight and immature in appearance. The only, difference had been the method of drug administration and the elimination of convulsive seizures in the mother. Are the effects observed due to nicotine intake per se or to the starvation and dehydration effects in the face of nicotine? When pregnant rats were deprived of as much food and water as the heavily nicotinized group, mothers lost weight and the neonates • were undem~eight at term. But, delivery occurred at normal times and the neonates, though lighter, had all the characteristics of term animals. It would appear that decrements in birth weight represent starvation and dehydration effects. Changes in the gestational period and signs of immature development appear to be nicotine effects. When exactly in utero, the developmental time schedule is slowed, and how nicotine acts to do this are still matters for further investigation. In the rat, at least, prematurity does not seem to be a salient feature, rather postmaturity with retardation in development. • 5020~ ~20

H. Ramm, Vice President R. J.

Dr. Thomas H. Kirschbaum and I have a grant from the Committee for Research on Tobacco and Health of the American Medical Association-Education and Research Foundation to study the effects of smoking on the fetus in utero and after birth. The project is divided into several parts. The first part consists of studying the effects o~utero-placental circulation, and fetal circulation and oxygen consumption in pregnant sheep. We would like to have tobacco in bulk form so we can burn it and channel the smoke via proper instrumentation to the lungs of the ewe. It seems to me that this way is preferable to burning cigarettes which would cost more in both time and money. If you believe it is not feasible to use tobacco in bulk form for these studies, could you send us a large number of cigarettes. Any help you might be able to give will be very much appreciated.

CA~CER field has tended to lend weight to this theory. Although no human cancer viruses have yet been isolated, ~'iruses that cause different can- cers in mice, hamsters, clfickens, and rabbits have been found. Dr. Charlotte Friend of the Sloan-Kettering Institute in New York City has discovered a virus that causes leukemia in mice. Using this virus, mice have been immunized against leu- kemia, or cancer of the blood, with some de- gree of success. This limited success in the field of animal experimentation holds real hope for human beings. The electron microscope has shown Dr. Leon Dmochowski and Dr. John A. Sykes of the University of Texas Medical School virus-like particles in leukemic cells of mice, chickens, and menmparticles that ap- pear to be strikingly similar. Thus, if a mouse can be inoculated with a virus against leuke- mia, it may be possible to do the same for man ~providing that the human leukemia virus can be found and a vaccine created. To this end, much experimentation on leukemia viruses is being carried on. Other scientists have been experimenting with limited success with vac- cines made from cancer patient's own tumors. The common occurrence of cancers in the same family has led to much thought about the part heredity might play as a Cause. Biologists 413 have been able, though with difficulty, to breed a cancer-susceptible strain of mice. However, most authorities at the present time agree that there is no real evidence to call heredity a cause of cancer. The fact that several cases occur in a family is regarded as a coincidence due to the increasing frequency of the disease in an aging population. Common Sites of Cancers Breast Crower: The leading cause of death from cancer among women in the United States is breast cancer. An estimated 64,000 new cases occur each year, of which about 25,000 are fatal. One out of every 17 women will have the disease in her lifetime. The common type of breast cancer affects a gland. It is most curable when found while still sn~all in size and con- fined to the breast. Hence, detecting it early is extremely important. This can be done by monthly self- examination which any woman can easily learn. The American Cancer Society has a film available for free showing on this subject. Also, regular visits to the family doctor--particu- larly if any suspicious lump is felt--are vital. Ninety-five per cent of women with breast lumps wait too long to see their doctors. In a Scotland study of several thousand women on whom breast cancer surgery was performed, the average size of the tumor was a little over an inch, three times the size of the smallest lump that can be felt. Lung Crower: The leading cause of cancer deaths in American men is lung cancer. About 40,000 deaths are recorded in the United States each year from this disease. Yet, a large portion of these deaths could be prevented if there were no cigarette smoking. The more cig- arettes smoked and the longer they are smoked, the greater the risk to the smoker. On the other hand, studies sho~v that in those who stop smok- ing, the risk of lung cancer decreases directly with the length of time they have stopped smok- ing. Pipe and cigar smokers who do not inhale run little risk of lung cancer, but they are more prone to cancers of the lip, tongue, and mouth than are non-smokers. Lung cancer is cured in only al:~out 5 per cent of cases even though the potential cure rate is as high as 50 per cent if operated upon in time. Unfortunately, it often gives no clue to its presence until it is too advanced for cure. Prevention by not smoking is the best protec- tion. (See Part XII, Chapter Three.) 5020? 7~130

CHA~'EK THREE SMOKING: FACTS YOU SHOULD KNOW AMERICANS SMOKE about 500,000,000,000 cigarettes, the equivalent of about 2,777 cig- arettes a year for every man, woman, and child in the country or over seven cigarettes per day. The smoking habit usually begins in the early teens. By the 12th grade from 40 to 55 per cent of all children are found to be smok- ers, according to one stud),. Another survey in American secondary schools indicates that about one of every four boys smokes cigarettes, and one of every, eight girls. The boys also are heavier smokers. This ratio follows through in adult life. Figures fluctuate, but it has been esti- mated that 60 per cent of American men smoke compared to 30 per cent of American women. Since 1939, numerous scientific studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and has permitted sound evaluation of the health risk. Based on evidence derived from human'population studies, clini- cal and autopsy studies, and animal experi- mentation, the smoking of cigarettes does con- stitute a definite risk to health. Skilled research personnel have conducted studies that prove tobacco smoking, particularly cigarette smok- ing, is associated with a shortened life expect- ancy. Cigarette smoking is regarded as an important factor in the development of cancer of the lungs, and cancer of the larynx, and is believed to be related to cancer of the bladder, esophagus, and oral cavity. Male cigarette smokers have a higher death rate from coro- nary heart disease than nonsmoking males. .Cigarette smoking is regarded as the most im- portant of the causes of chronic bronchitis in the United States, and is also a significant fac- tor in laryngeal cancer. A relationship does exist between pulmonary emphysema and cig- arette smoking, but it is not established that this relationship is causal. The majority of physicians and researchers believe these ob- servations to be corr,' .ey~d say, "Don't smoke! If you don't smoke, don't start." Some competent physicians and research perso, anal age less sure of the effect of cigarette smoking on health, although their number is d~s~dling. They believe the increase in these diseases may be explained by other factors in our complex environment, although evidence to support this view has not been forthcoming. Nevertheless the)- advise: "Be moderate if you must smoke." An individual may try to reach a solution about his own smoking by studying the evi- dence, ma "ldng a rational decision, and acting on it. Accordingly, let us review some of the evidence that has accumulated from the re- search of many investigators during the last decades. Ph~'slologlcal Effects What is smoke.'? Smoke, a product of com- bustion, is a mixture of gases, various Vapor- ized chemicals, and millions of minute particles of ash and other solids. These are drawn into the nose and throat during smoking and into the lungs by inhalation. The smoke includes some vaporized nicotine, a toxic substance found in tobacco, although much of it is changed by heat. It contains tars and other products from the partial burning and distilla- tion of the tobacco. A smoker gets more nicotine and tar if he smokes a cigarette to the end. A significant amount of carbon monoxide is also produced which is quickiy picked up by the oxygen- 454

You SHOUIcD ]~.WOW 457 Physicians, other scientists, and many health agencies have studied the relationship of smok- ing to health and most are in general accord. The most extensive examination of smoking was published in January, 1964, by the Ad- ~Jsor.v Committee to the Surgeon General of the U. S. Public Health Service. The committee reported that "cigarette smoking is causally re- lated to lung cancer in men; the magnitude of the effect of cigarette smoking far outweighs all other factors. The data for women, though less extensive, point in the same direction." The dangers in smoking, especially heavy smoking of cigarettes, are recognized all over the world. Statements on the subject have been issued not only by the United States Public ~-- Llealth Sen'ice, but also by the Royal College ." Physicians in Great Britain and a special committee of the World Health Organization. The American Medical Association stated officially at its Annual Convention in 1964: "The American Medical Association is on record, and does recognize a significant re- lationship between cigarette smoking and the incidence of lung cancer and certain other dis- eases, and that cigarette smoking is a serious health hazard." The House of Delegates of the American Medical Association has officially endorsed the actions of the Joint Committee on Health Problems in Education of the National Educa- tion Association and the American Medical Association. This Committee, recognizing that "the specific components of tobacco exerting "arnfful effects on the human organism have ..or yet been defined and the exact pathological and physiological actions of these components have not been determined, nor the psychology of smoking fully understood, recommended authoritative research...in smoking such as that being conducted by the AMA and others." The Joint Committee also resolved "that -schools, physiciang, health departments, and other community agencies cooperate in an ag- gressive program designed to discourage chil- dren from starting the smoking habit and to influence youth who are smoking to discon- tinue the habit." The American Medical Association has not confined itself to mere endorsement. It has never allowed tobacco advertising in its health magazine, Today's Health, since publication began in 1923, and it banned tobacco advertis-. ing from its Journal for physicians and its exhibits at scientific meetings in 1954, long before the hazards of smoking became scien- tifically apparent. It is sponsoring clinical and scientific research, as well as an educational program on a continuing basis to call to the attention of the public, particularly young peo- ple, the known evidence against smoking. Manufacturers are trying to reduce the haz- ards of smoking by modifying tobacco, reduc- ing nicotine content, and filtering tars. The long- range effects of these efforts are not known. Research has been initiated to find and iso- late or refine harmful substances so that those who smoke may continue to smoke safely. Thus far, the results have~been discouraging. As part of its concern with" this problem, the Amer'ican Medical Association is sponsoring a large-scale study to determine mechanisms by which human ailments may be caused or ag- gravated by smoking, in or.der to define more accurately the role of tobacco in diseas.e. While to smoke or not to smoke is a matter of individual choice, most authorities now agree that never to smoke is preferable[ Fur- ther, they would agree that significant evidence is accumulating which indicates the desir- ability for the heavy smoker to stop smoking or cut down to the point of moderation. The longer one smokes, and the more one smokes, the greater the risk of developing lung cancer. In those who quit smoking, the risk is diminished. Pipe smokers run more of a risk than nonsmokers, but far less risk than cigarette smokers. Medications are being sold which are tended to keep the smoker from smoking. Un- fortunately, these have not been successful. Antismoking clinics are being continually veloped and may help.many smokers. Persons who contend that smoking helps them control their weight by decreasing their appetites can find more healthful controls. Whether to smoke or not to smoke is a major decision for anyone to make. A person who has not started the habit should carefully consider all the facts before doing so. For those who really wish to discontinue smoking, the following suggestions are offered, out of the experience of a physician who suc- cessfully stopped smoking cigarettes, and has not resumed after 13 years. It takes doing, but it can be done. How to Quit Smoking To quit smoking is not easy.

THE AMERICAN MEDICAL 535 North Dearborn Street, Chicago, Illinois 60610 • • Area Code 312 527-1500 ASSOCIATION FOR IMMEDIATE RELEASE THREE-YEAR PROGRAM STIMULATES TOBACCO-HEALTH RESEARCH CHICAGO--Is smoking a psychologlcal addiction with deadly over- tones or more in the nature of a bad habit? The best estimate of clinicians and scientists in the field is that clgarets are a health hazard, But they admit they don't have the scientific data yet to establish why and how. The problem is one that must be answered at the cellular and molecular level• What effect is produced by the molecules that con- stitute cigaret smoke on the molecules that make up human cells? For the past three years, wide .anglng research into many questions at this level has been sponsored by the Project for Re- search on Tobacco and Health of the American Medical Association- Education and Research Foundation. But direct and incontrovertible evidence for a cause and effect relationship between smoking and dlsease--including cancer, respiratory and cardiovascular dlsease-- is difficult to obtain. The answers are probably still years away. 5020~ 7BS9
Page 446: 502077450
-2- Nevertheless, the program has already met with a degree of success, according to its architects. Explains Maurlce H. Seevers, M.D., Ph.D., chairman of the Com- mlttee for Research on Tobacco and Health: "For one thing, the program has helped stimulate an interest in laboratory research on smoking." In the past research into the effects of smokinghas often been retrospective in nature--attempting to correlate certain diseases with smoking patterns on a statistical basis. There was, however, only spotty interest among scientists in laboratory investigation of the questions posed by the statistics. Dr. Seevers, professor and chairman of the Department of Phar- macology at the University of Michigan Medical School, said grants provided under the AMA-ERF program are designed to change this by making it possible for scientists to undertake long-range studies. "Our goal has been to stimulate such interest among established researchers," he said. The decision to include cardiovascular and respiratory research in the program along with cancer, he explained, was based on the fact that certain respiratory and circulatory diseases show much the same statistical reiationshlp to smoking as cancer, and at the ~ame time are more prevalent than cancer. 50207 7~50
Page 447: 502077451
-3- The Project for Research on Tobacco and Health was initiated by the AMA House of Delegates as an adjunct to its educational cam- paign to discourage the use of toxic materlals--includlng tobacco-- among young people. The indictment of cigaret smoking as "a serious health hazard, was restated following the Surgeon General's report citing the statistical relationship between smoking and lung cancer and other diseases. At that time, however, the AMA delegates made it clear they did not think the report could stand alone. It needed facts to back it up. They indicated that statistical tabulations alone were not enough to dlsuade smokers from their habit. The role of smoking as a causative factor in death and disease--the mechanisms by which tobacco smoke attacks the body and the chemical agents, if any, responsible for the damage--also would have to be defined if any educational campaign were to be successful, they said. Much of the support for the research project was furnished by the tobacco industry itself, which pledged $I0,000,000 over a five- year period. Industry interest was in settling once and for all the question of whether smoking is or is not the cause of certain .diseases. Furthermore, the tobacco firms wanted to know if smoking $0~0 7
Page 448: 502077452
-4- was Impllcated in disease, was it due to some specific agent or agents in the tobacco which could be removed from the smoke. As Dr. Seevers explalned: "While the medlcal profession and tobacco industry have somewhat divergent reasons for promoting tobacco researdh, both are committed to basic scientific research as the best means of developing specific answers to the questions raised by our smoking population." "Certainly there are no scientific data that would contradict the basic tenets of the Surgeon General's report," he added. "I believe very few, if any, o~ the scientists working under this program would advise anyone to smoke. Still we hope that in search for facts, we can retain an open mind." All grants awarded under the program rest with the AMA-ERF and the research committee headed by Dr. Seevers. Other members of the committee are Drs. Richard J. Bing, professor and chairman of the department of medicine, Wayne State University; Robert J. Hasterllk, professor of medicine at the University of Chicago School of Medi- cine; John B. Hickam, professor and chairman of the department of internal medicine, Indiana University Medical Center; Paul S.

-5- To date 79 grants have been awarded, including four in foreign countries, and a total of $6,090,886 committed to research projects. Goals and guldellnes lald down for the awarding of grants are centered on "efforts to encourage and support studies to determine which significant ailments might be caused or aggravated by smok- Ing...those mechanisms by which cigaret smoking might affect health...and the particular substance or substances in smoke which might be the causal or aggravating agent." -0o 915167 50207 7~53

November 28~ 1967 , , INFORMATIONAL MEMORANDUM ~ ~-~ ~ SUBJECT: American Medlcal Association on National Interagency Council The AHA's House of Delegates in Houston Tuesday referred to the Boar~ of Trustees for study (and probably report at next June's annual meeting) a resolution proposed by the Colorado Delegation that A~A become a sponsoring member of the National Interagency Council on Smoking and Health. A reference committee reporting on the resolution recommended the action as follows (note reference to a 1968 report on the ANA-ERF tobacco research program): "This resolution seeks to have the American Medical Association become a sponsoring member of the National Interagency Council on Smoking and Health. The resolutlon states that the National Interagency Council plays a vital role in the dlsse~inatlon of information on the health hazards of cigarette smoking for the pur- pose of reducing the incidence of the habit in America. i '. "The polily of the American Medical Association recognizes the deleterlous effects of tobacco on human health. Efforts to educate the publlc to these dele- terious effects have been a continuing project of the Association for many years. Many pamphlets and other materlals are disseminated annually, and physicians are urged to educate young people about the health hazards of cigarette smoking to deter them from acquiring the habit. "The Amerlcan Medlcal Association Education and Research Foundation has an established research program under~ay to clarify the exact relationship of tobacco to health. The results of this program will be presented at a scientific session at the annual convention in June 1968. "It is apparent to the reference committee that the goals and efforts of the AMAand the Natlonal lnteragency Council on Smoking and Health in these educational efforts are comparable. Since Resolutlon 49 would have this Association become a spon- ~ sorlng member of another, addltlonal information about the costs involved and the pllcatlons of such a sponsoring membership appear to require addltlonal study and con- slderably more information than was available to this committee. "Mr. Speaker, your reference committee recommends that Resolution 49 be re- ferred to the Board of Trustees." Resolutlon 49 advanced by the Colorado delegation reads as follows: Whereas, virtually all physicians now believe that cigarette smoking is harmful to health; and Whereas, the National Interagency Council on Smoking and Health is playing a vital role in disseminating smoking and health information and in endeavoring to reduce the smoking of the American public, and k~ereas, official health actions by the A. M. A. have important Influence upon the American public, therefore be it, Resolved, that the Amerlcan Medical Association become a sponsoring member of the National Interagency on Smoking and Health. cc: Senator Clements, Ad Hoc Committee, General Counsel, ~0~0~ Company Public Relations Representatives

To learn if campus smoking policies for the incoming freshmen dictates to some extent his cigarette smoking patterns and to learn the place health occupies in the students basic value system, three groups of incoming freshmen and their roommates are to be studied. In addition to a control population methods used will include practices of non-Social acceptances of smokers and the use of intervention process techniques. ~ Dorothy F.

The acute effects of cigarette smoking on pulmonary ventilatlon-perfusion (9/~) relationships will be studied in normal individuals, those with obstructive .ai~ay disease, patients with diffuse pulmonary disease and with acute infections. The method of studying 9/~ will be the determination of alveolar-arterlal gradients and percenta$~ venous a~vixture while breathing 40% oxygen. It is planned to do these, studies before and after snaking, both at rest and following mild exercise in the above patient groups. In addition sir~lar studies are planned following the smoking of filtered cigarette s~mke. The potential modifying effect of bronchodilator medication prior to cigarette smoking will also be studied. Since ~/~ abnormalities are the primary cause of inadequate gas exchange in obstructive airway disease, these studies may pro~de evidence of the mechanistic relationship.s between smoking and obstructive air~:ay disease. In addition, this type of study may be able to serve as a humanmodel for the evaluation of effective filtration of cigarette smoke.

HILL J~ND KNOWLTON, INc. June 27, 1967 INFORMATIONAL MEMORANDa4 SUBJECT: American Medical Association meeting, June 18-22, 1967 Followlng are hlghlights of the American Medical Association Meeting held in Atlantic City, New Jersey, June 18-22: 1. The AMAnow has on record another resolutlon on smoking and health, which is a substitute for two separate and stronger versions proposed by delegates from.Ohlo and California (See memo dated June 22 for more detail.) 2. Copies of papers mentioning smoking and health are available on request. None appear to be of great importance. a. Labay, Peregrlna, and Boyarsky, Saul: "The Effect of Topical Nicotine on the Ureter." b. Porles, Walter J. et a__l: "The Treatment of Atherosclerosis with Zinc Sulfate." Co do Pe11, Sidney, and D'Alonzo, C. A.: "The Prevalence of Chronic Disease Among Problem Drinkers." Kershbaum, Alfred, PapaJohn, Douglas J., and Bellet, Samuel: "Effect of Smoking and Nicotine on Adrenocortleal Secretion~" Another paper, by Dr. Lee Farr, on noise pollution and other pollutants may be of interest chiefly because of his statement on page six where, in discussing smoking and respiratory disease, he said: "But, prior to the development of specific disability, it is impossible to indite a specific indlvidual as one of those who will, for example, with certainty, develop mallgnancy." Copies of this paper are being distributed to the ad hoc committee. 3. The Natlonal Clearinghouse for Smoking and Health had an exhibit in the scientific exhibit area. It consisted chiefly of three panels with text based on the attached handout (headed: "Physicians have stopped smoking. Why haven't their patients?"). Among the other material distributed from this exhibit: the diagram of a skeleton with diseases indicated (headed: "Distribution of Diseases Associated with Smoking); copies of "Medical Bulletln on Tobacco"; and copies of Clearinghouse antl-smokln8 literature.

4. It was reported privately to our observer at the meeting that the National Interagency Council on Smoking and Health has been trying to persuade AMA to Join as a member. The NIC, he was told, seems interested in getting a $i00,000 year gift from AMA for the NIC budget. There was no indication that AMA is considering Joining. 5. Dr. Milford O. Rouse, Dallas, was installed as AMA president. Dr. Dwight Wilbur, San Francisco, was named president-elect and will take office next June. / 6. Dr. Alton Ochsner was one of three recipients of a Distinguished Service Award from the AMA house of delegates. Just a few days before, he received the 1967 College Hedal of the Amerlcan College of Chest Physicians~ Ochsner recently announced that he would not do any more surgery. 7. In a meeting also held in Atlantic City, coinciding with the AMA, American College of Chest Physicians elected Dr. William E. Adams of Chicago as president. Adams is a long-tlmeAmerican Cancer Society official (director at large) and a member of the lllinols Division's Committee on Smoking and Health. He was also llsted as treasurer of the 1st International Congress on Smoking and Health, which was promoted by the American Temperance Society in 1965-66. 8. At the meeting of the National Association of Science Writers, the executive committee turned down -- unanimously -- a request by Emil Corwln, public information officer of the National Clearinghouse for Smoking and Health, that NASN Join the C1earlnghouse in sponsoring a survey of the smoking habits of the NASN members.

National ' Clearinghouse for Smoking and Health PHYSICIANS HAVE STOPPED SHOKIIqG. WHY HAVEN'T THEIR PATIENTS? The sharp reduction in cigarette smoking among physicians shows " that the physician is aware of this real threat to his health and is doing something positivd about it. In 195~, over 50% of physicians smoked cigarettes.. By 195~ the proportion of physlc£an.smokers had dropped to less than 30%. , Many physicians have stopped smoking because they know that the death rate for cigarette ~mokers in comparison to that of nonosmoker~ 70% higher from all causes 500~ higher from chronic bronchitis and emphysema 1000% higher from lung cancer. Those in the medical profession can be an important influence toward 'changing the smoking habits of people by: Instructing all their patients about the health hazards of cigarette smoking; Participating in com~unlty programs to help adult smokers give up smoking and youth not to start; Recognizing the importance of their attitudes and actions as non-smokers in ~ettlng an example.

HILL .~D I~NOWLTO.~0 I~c. INFORMATIONAL MEMORANDUM SUBJECT: AMA Passes Smoking Resolution The American Medical Association, by vote of its House of Delegates at the group's annual meeting in Atlantic City, approved a resolution on smoking and health Thursday. The resolution was a Reference Con~tttee substitute for two proposed resolutions (#22 and 6.4), which were more strongly worded. The text of the report of the Reference Committee follows~ "Resolutions 22 and 6~: The Reference Co~nittee considered these reso- lutions together. Several speakers spoke feelingly and infor~atively of the problem of smoking and health relating to the effects of smoking and approaches to improved health habits. The Reference Committee believes that the best interests of all concerned will be furthered by the following sub- stitute resolution~ Whereas the American Medical Association recognized and continues to recognize the deleterious effects of tobacco on hwnan health, and urges physicians to engage more actively in intensive education programs regarding smoking and health; therefore, be it Resolved, That the AMAreaffirm its policy regarding tobacco and health and vigorously continue its measures for corrective action."

Since alveolar macrophages provide a major defense mechanism against inhaled bacteria and other particulate material, this finding may be important in the pathogenesis of lung'dlseases associated with cigarette smoking. It is probable that the inhibitory action of cigarette smoke is biochemlc$11y mediated. Although preliminary studies of isolated components of tobacco smoke have not yet identified the active substance (s), the active component is water soluble and labile. ~ The present investigations propose a three-fold series of objectives: i) to isolate and characterize the active water-soluble labile principle in tobacco smoke that inhibits the capacity of macrophages to kill bacteria, 2) tb gain more insight into the metabolic effects of the unknown substance(s) in tobacco smoke on pulmonary macrophages, and 3) to gain more insight into the biochemical, physiological, and anatomical characteristics of the pulmonary macrophage system.

Comments and Critique by the Coeenittee for Research on Tobacco and Health Conference and Workshops for Rese~arch on Tobac,~co sued, Hea,l, th Abstracted from the minutes of the meeting of November 3, 1966 in Colorado Springs. Dr. Richard Btng ex~pressed disappointment in two of the reports given in his workshop that of Ntcoll on bat wing circulation and the Oser grant on air-way resistance. The Nicoll grant had already terminated. The Co.~ttee discussed the work of the Oser group and expressed dissatisfaction with the progress made. The Committee directed that in the final year of this award the group restrict itself only to a study of the 8uiuea pig plethysmosraph. (This has been doee ~ndDr. Oser has chosen not to request continuation support. Th~s project is therefore considered terminated.) Dr. Robert Hasterlik questioned support of Dr. P. O'B. Montgomery and stated that he felt the motion picture shown was not new and of little relevance to the objectives of the Co,~tttee. A discussion followed concerning this award and also the London award. The Co~nittee agreed that the time had come to reevaluate these projects and suggested a future site visit to Southwestern Medical College to do SO. Dr. Hlckam felt that the level of the papers was up and down, some were better than others, some hadn't progressed very far. He thought that the Committee had the right, when the situation occurred, to direct the investigator's attention to the fact that objectives of the program had not been met and that the investigator should be ~lven every chance to do so. He expressed pleasure with the meeting and opined it was a fine thing to have happened. Dr. Seevers stated that he was a little worried when he first came, but was now confident. Most people he had talked with said they hoped it would be a continuing type of operation. This, of course, would not preclude an open meeting. Dr. Larson suggested taking a specific area and getting the people involved together. 50207 7~182

-2- Dr. Singer added that in about a year an extra day might be added to the Co~nlttee meeting and one group could be convened at a time for discuss~ons or workshop sessions. Dr. Rites polnted out that the Coas~ttee had been handicapped by a finite amount of money and time and a lack of clear-cut objectives. He suggested that the Cow, tree consider itself a permanent group, and that he thought funding was assured for some tlue to come. Further, he felt that there was an opportunity for the Co~n~tttee to enter other areas. He cited the period when few people were Interested in virus diseases. The subsequent stimulation of research on such diseases--by a grant from the National Foundatio~ to the NIH--focused attention on the problem and provided for a man- power pool. At the first meeting of the Co~nLtttee attempts were made to identify areas of importance, and now, after this conference, another opportunity to name such areas ha8 come. The Consatttee might consider a fello~ship program and the assignment of people to definite areas. The Board of Directors relies 100~ on this Concretes. The only problem ae hand is to try to define new directions for action. Dr. Rites further mentioned that his opinions had chan~ed about some of the grants. Some were far better than he expected and others were not as good, but on the whole a favorable impression was made. Dr. Hlckam remarked that the NIH have a similar Job to that of the Conx~ttee. They regard themselves as a group try/x~ to reach certain ends; in 8o doing they must identify the areas which need additional study. The hard part of their situation is to try to attract good people iuco these areas and not to put people o££ too much by giving them the impression of completely directed research. Hany people are so attracted by n~ney they don't mind direction~ but they like it less when they are told exactly what to do. The problem is to try to identify the ends you want and keep good investigators attracted to the funds. Dr. Biug indicated his feeling that it was clear that there is a place for basic research and that the Comnfttee has followed these lines very well. If the Co~nittee were to fully reevaluate its position, it would not come up with anything different. He suggested that as Dr. Kotin becomes a more active member of the Comnittee, greater interest will be found among applicants in cancer research. Dr. Seevers pointed out that Dr. Bayne-Jones had said that the cancer area had not been given sufficient stress by the Commttte~. 50207 7~83

Remarks of Dr. Stanhope Bayne-3ones Confe.r.e.nce and .~,orkshops for I~esear.ch on Tob,a.eeo and Health Dr. Bayne-Jones expressed appreciation for the honor 8ivan h~n through the invitation to preside at this meeting. He said that this conference had great human significance because such a meting brings a mutual interest group closer together and gives individuals the opportunity for association, conversation, argument, and for making new friendships and consolidating old ones. He was impressed with the integrity both o£ the comnittee and the investigators and~rfth the abilities o£ the committee. The first grant was appro~-ed in 1964 and since then many thi~gs have gotten under way and many projects have even been completed. He considered this a significant accomplio~ment having produced sufficient material in so short a time--to Justify the confere~ce and workshops. Dr. Bayne-Jones mentioned that risks were involved in some of the projects using radioactive materials. He hoped that the committee has asked grantees to comply with federal safety regulations. This is important for the American Medical Association, the committee and the individuals on whom the experiments are being done. conclusion, Dr. Bayne-~ones thanked the AMA staff and the participants. "A good beginning is the secret to success, and you have done well." S020~ ~n8~

Remarks by E. F. Domino, M.D., R_=~p_orteur Wg~kshop on the Pharmacological and Psychophaz~nacological Action of Tobacco and Tobg~O COmponents Benedict R.~chesl, and Charl~s R%$chus.t~r~.Ph_..D_. This s~udy is designed to determine the role of nicotine in smoking habits of normal volunteers. Previous investigations which attempted to assess the role of nicotine in smoking suffered because the patients wanted to stop smoking. Furthermore, the patients frequently had a variety of disease sta~es. The present investi- gators took elaborate histories to assure tha~ the subjects were normal. The subjects were under ~he impression they were being studied for the effects of drugs on performance. The investigators had to es~abllsh the proper dosage of nicotine, but when they were successful in this there was no change in any of the behavloral measures. Essentially it was shown that there are physlologlcal and psychological components to cigarette smoking. Approximately one-thlrd of the results were from nicotine and two-thlrds were from other substances or were psychological. Gerald A. Deneau, Ph~D~ This study has many ramifications. I~ is essentially concerned with four elements of drug dependence: tolerance, physiologic dependence, psychogenic dependence, and antlsocial behavior. Followlng nicotine administration to monkeys, there is tolerance development; no physiologlcal dependence or withdrawal symptoms; clear psychogenic dependence; and no significant antisocial behavior. Nicotine is therefore a habituating drug bu~ is not truly addictive. These effects are apparently not due to catecholamlne release. lrvlng Geller, Ph.D. Dr. Geller described the effects of drugs on the timing behavior in anlmals. No data was presented on the effects of nicotine. Dr. Domino thought Dr. Geller needed pharmacological help and thinks this workshop helped him in this respect. $020"/ "/~ 88
Page 479: 502077489
-2- ,Cha~r!es J. Ke.nsler, Ph.D. Dr. Kensler used reasonable pharmacological doses of nicotine equivalent.to those a human being gets when he smokes. Quite remarkable in that they were able to show, depending on behavioral situations, nicotine as well as other drugs affected behavior in a variety of ways--either stimulant or depressant. Dr. Domino was impressed, that in general, nicotine was like amphetamine with a clear-cut stimulant effect. Studies of the interaction of nicotine with caffein were especially interesting. Combinations with alcohol and other tranquilizers should be studied. Nicotine and caffetn potentiate one another. Professor Danlel Bovet Dr. Bovet studied the effects of drugs, including nicotine, on acquired and innate behavior. He pointed out the importance of strains of mice. Nicotine depresses learning in smart mice and facilitates it in dumb mice. .C.arl G. Schmlt.e.rlSw, M.D. i_ Ph.D. This research by Dr. SchmlterlSw showed how nlcotine in mice and cats distributes in a variety of tissues especlally the brain. This clearly indicates the importance of the brain in nicotine studies. Most of the work was with nicotine and some'of its metabolltes. Herber~_McKennis, Jr,, Ph.D. The purpose of this study is to determlne.nlcotine metabolism and what happens as it is converted by the organism. The bio- transformation of nicotine is an extremely complex problem. They emphasize that nicotine is converted to many other things. This is good work and it should be continued. Charles H. Jarboe~_ Ph.D. A sophisticated approach was presented because he was trying to understand more of the pharmacology of nicotine and related derivatives in a quantitative manner. He is making hi~ own nicotine derivatives. Dr. Domino gathered that he frequently had problems • such as getting resins. Dr. Dominots impression is that he needs an organic chemist to help him but what he is lookinZ for is a selective nicotine antagonist. 50207 7m89
Page 480: 502077490
-3- Herber~ McKe~nls, J~o, Ph.D. Dr. McKennls Is. trying to find better methods of measuring nicotine. We need to know more about how much nicotine is absor~ed, how it is distributed and metabolized. Excellent work and should be continued. Carl C. Pfelffe~, Ph,D...,. M.Dt and ~en;y B. Murphree. M.D. They used extremely elaborate electronic and computer techniques to measure and quantify brain waves. Measurements are very precise but would raise the question of whether they are viewing the trees ra~her than the forest. The work done to date is good but the results presented were extremely preliminary. Humans who smoke clga~s and Inhale show a mild amphetamine effect on brain waves again showing importance of brain in tobacco studies. They did not relate this to nicotine. They will study nicotine soon. Gerard L. Gebber ~ Phi. D.~. This work is important because it has shown a new effect of nicotine on autonomic ganglia. Gebber achieves facilitation of autonomic ganglion transmission that lasts for hours. Roy D. Hu~son~ Ph.D. He may be getting at the antl-appetlte effect of nicotine. Georg~ B. ~e.~ss, P~D. Dr. Weiss is studying the actions of nicotine on muscle con- traction. It is very interesting pharmacology. Saul Boyar~ky, M.D. The study of nicotine is a side issue. Ureters have been thought of previously as passive tubules. In reallty, they have a fantastic mechanism for pumping~ dilatlng.~ etc. Eventually this will lead to the s~udy of patients while they are smoking to determine what happens to ureteral action.
Page 481: 502077491
-4- Charles~ R. Zcht.L M:D~ and-Richard W. Stande.r~ M.D. This was a clinical study showing that when women smoke during the end of gestation the.uterus is more irritable and the babies of some of the women kick around more. R. Frederick Becker~ Ph.D. Dr. Becket has done a large amo~mt of work. He can duplicate in rats what we know happens to women; heavy smokers have smaller babies. The question is what exactly causes this. The importance of this study is that the investigator went beyond nicotine and measured food and water consumption. Rats that don't eat and drink ~mll have essentially the same problem as female rats on nicotine. 50207 7qgt

Remarks by Alfred P. Fishman, M.D., Ravvorte~ W_0rksho~_on the,. Rel.at£or, shtv Of Pulmonary ~r0 Krumholtz end C.~R. ~oolf. H.D. Drs. Krumholtz and Woolies papers were dlrectly related. Dro Krumholtz extended studies done for a long time using previous controls to assess what happens to chronic smokers. A remarkable thing about his observations is that if a chronic smoker quits, he shows dramatic changes in pulmonary performance in a period of 3-6 weeks. He intends to continue observations up to two y~r$. Dr. Woolf, who studied women with a somewhat similar technique, found heavy smoking causes no change in pulmonary performance. Dr. Fielunan raised the question that if there is no change, how can it be reversed in 3-6 weeks? He dldnWt think a change llke that can show in three weeks. What would help here Is--(1) a clear definition of "what is a smoher?"; (2) how many subjects had bronchitis clinically?; (3) did they all have somewhat similar lun~ function tests? I think they and Dr. Yrayser would benefit fromtalking to each other. This might help others by defining some"sort of standards. Regi.na. Frayser. p_h,D. As a result of accidental observation of oxygen debt during exercise, Dr. Frayser has embarked upon measuring concentrations of all sorts of enzymes in blood. The key questions here are~ ~ny is this piece of work being done? What is one looktn$ for? Whae does one expect to find? Dr. Flshman is not at all certain about why they are measuring enzymes. Jerome Elia,,s,,Cohn! M.D. This is one of the papers where technique is being set up to analyze blood flow and ventilation. There is nothing really new about the technique because it is fairly standard now to use the substances cited for these analyseso This will be useful to general physiology.
Page 483: 502077493
-2- Dr. ,.Te.mple (Paper Was presented by Herbert O. Sieker, M.D.) Dr. Sieker gave a very interesting approach to analyzing blood flow and ventilation in the lung. He probably will do little as far as orlglnal objectives which probably would be to determine minor degrees of abnormality which you get in bronchitis. Instead, Dr. Fishman thinks they will come up with a method which will be useful in detecting gross abnormalities in blood flow and ventila- tlon. ~B.enJamln _H. Le~Is. M.D. This is interesting research in pulmonary physiology. Obser- vation is quite slmple: there is a pattern of breathing in the normal patient which is different from the abnormal. He used a computer to solve the question of why but it really does not have much physlological meaning at the moment because no one knows whether what the computer produced has a1~ything to do with wha~ the anlmsl produces. .Kenneth_M. M,.,ser~ .M.D. This again is a prellmlnary kind of statement of what wil! be. It is very much accepted now to use scintillation cameras to obtain pictures of ventilation and blood flow in the lung. There is a question of whether one method has any advantage over another. One problem in the use of sequentlal studies is that the radiation dose becomes important, Several questions from the audience were dismissed rather lightly but think that this will be a very serious problem in scanning, Dr. Fishman recommended to the Committee that they be rather careful about the amount of radiation given to patients. Dr. K~Iburn '"(Tak~ £~omvr. Herbert O. Sieker~s grant) His work was presented as something new. Actually it is not new but it is quite good. It was first done in the early 1920~s with a frog lung. This is a direct outgrowth; better with the frog lung than in manna allan lung. Nevertheless, it could be an important way to look at the lung.
Page 484: 502077494
-3- .Ian T. T. Hlgglns~ M.~. Continuing the tradition of the British eptdemio!ogist who gets himself a little town wlth a Salvation Army depot. He is using the same techniques used in mining towns in Wales. It will be very well done but not very much new will be learned. He and his group have a fiendishly clever way to create particles of known size for distribution to the lung of both man and donkey. Because of this, they can predict rather well where the particles go. Dr. Fishman was disappointed that this group has not attempted ~o examine the lung microscopically to determine if any iron oxide remain. They admit some do not come back, especially the smaller ones. Dr. Fishman has some reservations since they are also using radioactive materials. (Dr. Domino mentioned the new PHS rules for studies involving the use of humans. He wondered whether the AMA, in an effort to protect itself, should insist that all grants go through the human use co~nlttees now in existence at every center using PHS funds°) William H. Anderson, ~,D... Here we have a poorly designed experiment as well as a poor performance. He starts with a new histological technique which involves using lOOZ CO2 to prepare tissues for examination and then exposes rabbits to hearty doses of smoke in a system which allows accumulation of carbon monoxide, etc. Dr. Fishman thinks that no one can ever m~ravel this. ~errill A. Bender~ M.D~ Dr. Bender is doing external scintillation counting using NaI crystals as detectors. The test substance is p-iodobenzolc acid labeled with 1132. Involved in a very interesting, compllcated electronics system where indlvidual counters feed information in such a way to computers that he gets both a dlgltal readout and an analogue readout which is more representative in time. Entirely in the developmental stage. He has to develop more instrumentation to record rapidly enough to get serial film of events in the lung. Dr. Fishman thinks the work is good--skilled electronlc gadgetry with a direction. 50207 7~9~
Page 485: 502077495
-4- Gar.~e~h M" Green~, ,~.D~. This is a serious and impressive piece of work. It will probably succeed in identifying individual components of smoke that may have deleterious effects on the behavior of the two mechanisms. ,R,~bert G. _,L, opdon~,' M.D. Dr. Loudon is doing interesting work which may hoe be closely related to the problem at hand. He is studying systematically patterns of a cough and its acoustic components. He has a lot of imagination but one could quibble about some of the data he presented today. ,T,o~e ,Dalh~, M.D_. It is a curious kind of work. Dr. Fishnmn thinks It may be interesting but it is not the kind of work he would enjoy and does not know what conclusions you can draw from lt. He uses a pharma- cologlc rather than a physlologlc dose of the agents and his results may be subject to debate. _~ohn J_, 5_a!len~er, M.D, Dr. Ballenger gave an interesting and ~amattc approach. Dr. Flshman is not sure of what ultimate value this study will have. OsGar. K. Reiss,,, He has shown by elaborate techniques that the black pigment of the human lung occaslonally is something other than carbon such as ferritin. ~Dr. Richard Ehrlich's grant) He found that tobacco affected mice's resistance to infection. 50207
Page 486: 502077496
-5- s mu.el T. J. Gia. . ,ona , M.D. and Watts R, Webbo M.D. Both were concerned with surface active material in the lung. They used different techniques to obtain materlal and both agreed smoking modifies the surface active material. There was a little disagreement about exactly what it does but both are agreed it may be in part responslble for the emphysema which occurs. Dr. Fishman has serious doubts about this interpre- tation and thinks Dr. Hickam does also. One does not know how much surface active material one needs to get the "anti" effect. Dr. Fishman also thinks it is very fashlonable and will go on forever but will not end the question. As such, the studies are well done but will not answer the question of whether the surface active materlals are seriously affected by smoking to the polr~t where they are involved in the pathogenesis of emphysema. 50207 ~96

The animals to be used are pregnant "sheep, monkeys and cats. Maternal and fetal arterial pressures, uterine and umbilical blood flows, maternal and fetal pO2, pH, pCO2 and carboxyhemoglobin will be measured in control, smoking and recovery periods. In a series of chronic experiments on pregnant sheep, maternal and fetal circulatory and respiratory parameters will be measured in the conscious state in control, smoking and recovery periods. In the smoking period,.the sheep wili be placed in a specially constructed chamber with the atmosphere saturated with cigarette smoke. The human investigation will be carried out on pregnant women in various periods of gestation. The effects of smoking on maternal hemodynamics will be recorded. The time for initiation of breathing by the newborn will ~e recorded in the smoking group and compared to that of nonsmokers. Fetal ).food composition will be analysed in infants born to a group of smokers and compared to that of nonsmokers.

Nicotine and related drugs modify neuromuscular transmission from postganglionic sympathetic.nerve terminals to vascular smooth muscle. We plan to extend studies already initiated into the mode of action of nicotine at this site using classical pharmacological and also isotopic techniques. Our ultimate aim is to gain an understanding of the home- ostatic mechanisms which control the release and uptake of the neuro- humoral transmitter in the adrenergic neFve in blood vessels and the way in which nicotinic drugs modify these. b. An in vitro Study of Human Blood Vessels. It is proposed to study under controlled in vitro conditions, various physical, physiological and pharmacological characteristics of human blood vessels and correlate these parametePs with their his- tology, objective evidence of cardiovascular disease and smoking his- tory. It is hoped that significant and suggestive observations will emerge that will lead ¢o a subsequent definitive investigation. SIGNATURE OF PRINCIPAL INVESTIGATOR .. . John A. Bevan, Assoc.

The aims of this project are to delineate the action of nicotine at the cellular level'in a number.of d~fferent muscle systems and to obtain data indicating the points at which nicotine acts in the excitation-contraction coupling sequence-in muscle. Preparations to be employed are frog sartorius muscle, frog rectus abdominis muscle, rabbit aorta, and longitudinal smooth muscle from guinea pig ileum. Experiments will be designed to yield information concerning the relationship of nicotine actionto ion movements (Na22, K42, Ca45), and to the actions of procaine, nitrate, iris, IAA, nialamide, high potassium, and pH. Emphasis will be placed upon-the measurement of tension and calcium ion movements (Ca45) as parameters of particular importance for characterization of nicotine actions. It is anticipated that correlations found between the actions of nicotine and those of these-other agents upon ionic movements in different muscle systems will lead to a better understanding of the mechanism and site of action of nicotine.

By Charles A. L~4~:l.strs~ Hore than a year ago. with other members of theSurgeon General's' Advisory Co~mittee on Smoking and Health, I attended your first con- £erence in Washington. The .date o£ your meeting, I recall, marked the first anniversary, on January 11, 1965, of the Comitteees report. I assume that an important purpose of your meeting in the next two days will be to undertake a critical and thorough examination of the progress and shortcomings of action taken thus far in response to the Advisory Con~nittee~s report. I am delighted to participate in this undertaktugo At the outset, I would like to present my understanding of the task. The call to action two years ago was clear enough. The Judgment of ° the Advisory Co,~nittee, after a careful evaluation of evidence in more than 10,000 studies, is summed up in that sentence so familiar to us all: *'Cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action." The conclusions of the committee were sound and they have been confirmed, extended and strengthened by subsequent research.
