One relatively immediate application
of this research aiay be in establishing
a therapeutic index of the effect of
treatment on eancers of the herpes-
retatca types. tneh tevcts ot anuo.ooy to
the nonvirion antigen persisting after
therapy would be a sign that things
were not going well, and, perhaps, treat-
mcm etlulu Uc aU)ulleLL accun7ingiy.
Conversely, an absence of antibody
would be a good sign.
Further in the future, Sabin says, is
the prospect of a vaccine. Although he
has been, for the last couple of years,
an outspoken critic of the notion that
there is any point in hoping for a vac-
cine against cancer, he says that his
skepticism is over the prospect as far
as it applies to RNA viruses, not DNA
ones like herpes. (bfost of the claims
:°at ya ^, L,-n sw-1c u.' the diswvtrl
of' a human cancer virus have been
about RNA viruses, which, presumably,
are vertically transmitted from cell to
rci1, fro:.t ccseradion to generation. if
so, everyone carzies these viru* from
conception, ard the thougt,t' of vac-
cinating again~t them in ai traditional
sense is impractical. Furthcrmore, vir-
tually all of these RNA viruses are
known to be oncogenic. The potential
hazards of injecting them in anyone
are obv _ious.)
But, as Sabin sees it, the situation
with the herpcsviruses is different. "If;"
he says, stressing the if, "w'e could-
find strains of herpcsviruses that are
infectious but are definitely not onco-
genic, it might be possible to develop
an attenuated vaccine which would
produce immunity to all forms of
herpes, includinF the oncogenic ones.'
But that is a very long way away, if it
happens at all." Nevertheless, Sabin.
who only began working at the Fred-
erick center in January, is optimistic
about the chances.
The woik that Sabin and Tarro have
just completed after weeks of intensive
effort began. in a sense, as IonF ago
as 1965, whc.4 Tarro came to Sabin's
laboratory in Cincinnati as a post-
doctoral studcnt to learn virology. At
the time. they were looking for ways
to identify nomirion antigens and pre-
pare them for laboratory use by sep-
arating them from thc virus antigens
with which they are associated. "There
was a long period bf poking around in
the proverbial dark room looking for
a black cat that may not be there."
Sabin says of the time, using one of
his favorite cxpressions.
During that pcriod, the two Cncin>
nati researchers did some work with
Arid Hollin.hcad of George Wash-
ington University, whose studies fo-
cused on ways of identifying, isolating.
and characterizing specific virus-in-
duced tumor antigens. That marked tbe
oegmrnng oi a ctose association be-
tween Tarro and Hollinshead which
has continued to this day. Their most

Two ~'atentStudies Pending ~

In her maiden speech as Assistant Secretary of Commerce for Science
and Technology, former-Boeing Company physicist Betsy Ancker-Rit,n- '
son announced that two programs to put the department's file of I1
million patents to work in aiding American technology are under r:~ay.
with some preliminary results expected soon. -- --
Speaking to the Washington Chapter of the National Association of
Science Writers, Ancker-Johnson said that the larger effort is to break
out the data in the Patent Offices mauivR files of 11 million patents
(which already divides new inventions inta 85,000 subclasses), to iudi-
cate where technology is advancing rapidly, where it is proceediog more
slowly, and who literally owns it, The premise, she said, is that "Chang-
ing patterns of patent activity . . . can be an accurate Indication of
technological activity throughout the world:"
Patents granted in tunneling technology are one example. "U.S.
inventors clearly dominate In the broad field of hydraulic and earth
engincering, with 69 percent of the patents. However. In the tsubcategbry
dealing with tunneling, the figures are quite different. The U.S. shatc is
only 31 percent, while Germany, with 37 pereent, emerges as the nEost
active country." ' In citing this sort of example. Ancker-)ohnson was
reflecting a feeling shared by others in the Commerce Department and
in Administration science circles that, Increasingly, American scientists
and technologists should keep a weather eye on their foreign competi-
tion. At present, she erplained. Commerce is preparing a prdimina,ry
report which will suggest fcrmats and categories for breaking ouc this
kind of patent information for use by busibess and government.
A second, smaller effort she cited is a review of the :5,000 gosern-
,ment.owned patents to see which might be turned into profitable com-
mercial ventures, or, in her words, into "acres of diamonds" for industry.
The effort here, according to a department spokesman, is a result of the
Ptssident's Technology Alessage of March 1973. If AnckeMohnson's
speech, with its concluding pitch for women's rights, is an indieation,

In Naples. Tarro, who is described

retiring young investigator, .vorked
under a grant from the cancer insti-
tute which, Sabin says, he got because
he /Sabin) would continue to be asso-
ctated with the project. By the late fall
of 1972, Tarro's work in Naples had
progressed, so far that he was able to
say that there was a clear relationship
between harpesviruscs and several hu-
man cancers. Says Tarro. "In Novem-
ber, we got some very nice results.

' he was the first person to be informed-
he said they were 'too good to be
true.' " In February, Sabin sent a joint
Sabin-Tarro paper off to the Proceed-
ings, where it was published in the
Anriy issun,. S.thin viho was hv this
time back in thc United States, also
asked Tarro to come to this country
for a stay in his laboratory at the
Frederick center. Tarro arrived in Feb-
ruary and will return to Italy soon.
According to Tarro, the work he and
Sabin did at Frederick was a "repe-
tition" of the work he did in Naples,
although it was done with more "so-
phisticated" equipment and with dif-
ferent controls. A travel order to Tatrro

partially supports Tarro's contention
that the work he did in the last 3
months cssehtially duplicated previout
work: "Dr. Tarrm will participate in a
collaboration with inv`o3tigaRors at the
'Freder*ek Cancer Research Center to
verify and extend observations made
on human cervical carcinoma patients
by techniques deinBloped,by Dr. Tarro
in Naples."
Once back, in Italy, Tarro hopes to
continue his research'along the same
lines he has been pursuing and to con
tinue his collaboration with scientists
in this country, including Hollinshead,
even though Sabin is reportedly less
than pleased about that. 1Vhen asked.

National Academy of Sciences
The National Academy of Sciences
devoted its spring meeting this year
mainly to commemorating the 500th
anniversary of the birth of Copernicus
and to discussing the scientific revolu-
tion he did much to initiate. On more
immediate problems facing science and
society, the academy members also
tended to take the long-range view.
It would be unfair to suggest that
the academy has relapsed into the com-
placency of the past. A lot has hap-
pened to the academy in recent years,
and it is now in a period of consolidat-
ing the changes that have been made
the members arc in no mind to sec any
major rocking of the boat.
Asked to characterize the atmosphere
of this year's meeting, academy presi-
dent Philip Handler replied, "Quiet "
Handler says hc feels that for several
years the problems-tPat were on the
minds of many membcrs had their
origins in the Vietnarii war. "The matter
of 'our relationship with the military-
classified activitics-has been regu-
larized. As far as I know this has satis-
fled the concerned portion of the ment-
bership."
The issue of secrecy of the military
work accepted by the academy was the
$74
cause of sharpest dissent among acad-
emy members in recent years. As a
result of the criticism, the academy
last year adopted new rules on classified
work which essentially provide that
members be Informed of the nature of
classified work before the academy ac-
cepts it and creates-machinery through
which members can protest and have
a particular contract rejected.
The debate over classified work and
the compromise reached led to the
resignation of two members critical
of the sittration. Richard Lowentin of
the University of Chicago and Bruce
Wallace of Cornell. Technicalities had
left the resignations in limbo until this
year's meeting, but the academy coun-
cil this year clarified the situation by
changing the bylaws to provide a di-
rect means of resigning and also, so
to speak, left a light in the window by
adding that a resigned member may be
reinstated after not less than 4 years
by a two-fifths vote of the council.
11'hat seemed to concern members
_most thts year, according to Handler,
was thc-°funding of the_ scientific en-
deavor." He said that "the most acute
concern was expressed by biomedical
researchers." He suggested that this
J
may be the case because "bthers felt
the pressure earlier."
On another internal matter that has
troubled the academy for several years,
the members received the formal word
that the leadership of the National
Academy of Engineering (NAE) was
recommending dissolution of its decade-
fong partnership with NAS (Scfence,
13 April). NAS members received the
news calmly and approved a discreetly
worded resolution invidag NAE to co-
operate with NAS in matters of "mu-
tual and overlapping concern," and
adding that if NAE decides to remain
under tlx NAS chairter, "the iavitation .
to do so remaias open"
There was really not much else that
NAS could do sinse NAE was sched-
uled to mebt the following week, and
the decision to stay or go rests with
a vote of the NAE members. In the
event that the-decjsion is-to-stay with
NAS-considered against the odds-
the two academies would reopen nego-
tiations. Theae nagotiations seem to
have stuck mainly on the issue of how
the two academies koulr jointly operate
the National Research Council (NRC),
the framework otganiration for the
voluntary committees which perform
the academy's funetion of advising the
government. - - -

From the viewpoint of arma conttol

In a telephone. interview, Sabin
sarssed the fact that there must be co-

which is produced by a, cell that has
been infected by the virus "and that uses
a piece of DNA from the virus in the
production ptocess. Thus, it is the viral
information that codes for production
of the antigen which, while specific
to that virus, is not a ittuctural part
of the virus itself. These nonvirion attd-
gens, like 'any other antigens, stimulate
antibody production. ~
In experiments conducted during
February, March, and April at the
NCI's Frederick Cancer Research Cen-
ter in converted Fort Detrick, Sabin .
and Tarro screened a variety of human
serums for antibody to the tsonvirlon
antigen. They found it in serums from
patients with advanced cancers of the
following nine typesr Gp, mouth, oro-
pharynx, nasopharynx, kidney, bladder,
prrstate, cervix, and vulva. There was
no antibody in serums from patients
with 20 other types of cancer, including
cancer of the lung,-s-tomach, colon, and
breeast, as well as a couple of~types of
leukemia. Nor was it present in fetal
tissue, thereby discounting the poui- }
bitity that the antigen in question is
really an embryonic one that is fre-
quently assoceated with various cancers.
