The subkth.l eoncentntions o/ B.P. which did aot affect either (1) cell growth. or (2) amino acid tnnspoal or (l) rotal protein synthesis or desradaion, did however inhibil specifically harmone synthesis by these cells.

A concentration dependent stimulation of microsomal BaP rronoo.ylienase activity was observed in nicotine or BaP treated cells. Tbe effects of :fiese substances on aimulalion of BaP monoosylleaase activity seems 1o be additive.

EFFECTS OF SELENIUM AND SULFUR ON METABOUSM OF BFJdZA>foIPYRENE BY HUMAN PULMONARY ALVEOLAR MAt.'ROPIIAGES The interactinn between trace metals .nd polycyclic acronutic hydrocaibons (PAlls) has attrneted increased irresesl recently since some Ir.ce metah, inchding seknium, have been shown to decrease chemical carcirror nesis.

M111.TIPI.ICITY ()F CYT(x11ROME P4S01N PRIMARY FETAL IIL'PAl (X.'Y7FS IN CULI URE The pmnnaW period of life is a critical time for the quantitative and qualitative development of marosomal monoosygenases, and earlier observations suggest that fetal hrpaoeytes in cuhure might constitute an ideal lool for studying the perinalal re6ulaatry mechanism o( mowoosytenases. Whik it has been known fa a whrk Ihat Primary fetal ral hepatocytes in c.Nve display difkrenl monoosy`enase activities which can be induced by sevenl chemical indreen. these hep.tocytes were believed wmi now to produce only one single eytodnome P-IS0 species, namely the cyto- chsorne P,450 (ar P4IS).

A FAMILIAL AGGREGATION OF PANCREATIC CANCER: AN IN VITRO S7vDY Pancreatic cancer, with its olncwe etiology and diffscuh early diagnosis, presents a medkal problem of slaggenng propurtions. In the in vitro study presented here, a family was identshed in which four individuals manifested pancreatic cancer verilied through two generations Cell cultures from split-thickness skin biopsy specimens were nblauied frr 24 rnembers fnsm three jenetNions (17 bMrdlirse relatives, seven family memBen by inarruge) as well as len noefamily normal subjects, none with a lamily hwory of aild sunrxs One of the conslam features of human nwNwolayer dcrmal (ultunrs has been dipN»dy On the other hand. hypenhploNly. other than 1et..pkidy. has been rarely observed in cultures fmrn.ormal subjccts without a family history of solid tunwus. In this shdy, however, increased in vrtru hyperdiploidy was observed in eight of the 17 family members /esled. In the long run. allregates of pancreatic cancer in families such as this one. and the occurrence of pancreatic cancer in sonse .wosornal domiarst cancer syndromes have added credence to the relevancy of agenetic component(s) in a fnctioa of patscreMic eancers. ln an important way, this study has demonstrated the potential lnr eombirdng detailed family data with rocogni- lion of in vitro biornarters for caucer pronencss an am approach ao rhe cornpehension ol carcinopeesis in pancreatic caecer.

Smoking histories of pwbands and their relarives were obtained for an oveslappinR series of 60 hrtg ea.ces prob.nds and 7111 psnbands with other smokiy- wociarod romors.

A cohun treed for hrsg cancer was also appareM amons reftlives of breast cancer prolwsds, but not for relatives of colon caarer pro• bands, suggesting the posublNy of an intrlnsic association belween carcinoms of the baast and lung.
