Cancer Scientists Turn Interest To Venezuelan Virus
mm

By DELOS SMITH
UPI Science Editor
New York - OTH - In can
cer science there is a sudden
Interpst in a virus which in
flames the
brains of
horses. When
put into eight
human beings
with far ad
; vanced cancer
i it appeared to
! prolong t h e
; lives of three
of them. The
DMoi sroitb interest is not
engendered by that medical
ly meaningless statistic. It
grows out of scattered inci
dents over the past 60 years
In which a viral infection pro
ducing fever seemed to in
terfere with cancer growth.
"Fever therapy" for cancer
has long since been discred
ited, however. It rarely seems
to work. But the horse virus
has scientifically raised this
question: Could it be a virus
specially endowed with chem
ical properties that interfere
with one class of human can
cers? The virus is the one which
causes Venezuelan equine en
cephalomyelitis (brain inflam
mation). It is closely related
to viruses which cause the
same disease in animals in
other parts of the world. Oc
casionally human beings get
infected with them. Their
brains become inflamed, of
4im with a fatal outcome. The
viruses are spread by insects,
usually mosquitoes.
The Venezuelan virus
VEE came into this experi
mental picture because there
is a strain of it which was
taken from a Trinidad horse
in 1943 and has been kept
going in laboratory cultures
ever since.
Workers Infected
Fifty laboratory workers
have been infected wilh it
over. the years, by accident.
Not one developed brain in
flammation, although all had
brief illnesses with high fe
ver. That made it seem non
lethal for human beings al
though it was highly lethal
in mice, guinea pigs and other
animals.
Nevertheless it has been
"attentuated," that is, weak
ened, by laborious laboratory
procedures with the idea of
producing a vaccine to protect
laboratory workers against
I the full . strength virus. This
attenuated VEE attracted Drs.
W. D. Tigcrtt, W. II. Crosby,
T. O. Berge and their associ
ates of Walter Reed Army
Medical center in Washing
ton.
In 1952 other doctors put
another brain - inflaming vi
rus the West Nile virus
into patients with far advanc
ed cancers of the kinds which
arise from the body's lymph
cells. The cancers seemed to
shrink, but the patients de
veloped brain inflammation.
Attenuated VEE might re
tain any anti-cancer powers
it might have although de-
I prived of brain - inflaming
properties, the Walter Reed I
scientists reasoned. They put
Edison Honored During

son was honored at the Ore
gon Legislature Monday for
inventing the light bulb 116
years ago.
All lights in the House and
Senate chambers were turned

Speaker of the House.
it into eight lymph-type can
cer patients who apparently
were doomed. All known
treatments had been used in
them and all had failed.
Four were so far advanced
in disease their life expec
tancies were measured in
days. In only one did the vi
rus so much as cause a fe
ver. All four died when ex
pectcd and their cancers were
unchanged.
Feverish Illnesi
The other four had life
expectancies measured in
months. In all the viruses
produced an acute feverish
illness of several days dura
tion. When that was over
their pain and other cancer
symptoms disappeared, fur
thermore, there was objective
evidence of a shrinking of
their cancers. There was no
"cure," of course, but their
lives were prolonged many j
times beyond the medical ex-;
pectancy.
In carefully measured con
servative language the scien
tists reported this to the tech
nical organ of the National
Association for Cancer Re
search. They suggested the
study of VEE in patients with
less advanced cancels was
"warranted." You may be
sure these studies are now
under way.

Retail Prices of
Food Expected To
Stay About Same
Washington -WPP- The Agri
culture department says that
retail food prices in the first
half of 19G3 are expected to
average about the same as a
year earlier.
Higher prices for fresh
fruits and vegetables, hit by
freezing weather, are expect
ed to be offset by lower prices
for beef, pork and eggs.
In a review of the national
food situation, the depart
ment noted while the current
quarter is the low-supply sea
son for foods such as fresh
vegetables, some fresh fruits,
and fishery products, the pro
cessed forms of these foods
are in large supply.
Expenditures Up
The department estimated '
consumers spent about S74
billion for food in 1962. This
was somewhat more than 4 j
per cent larger than food ex- j
penditures in 1961. Per capi- j
ta food outlays increased 2.8 i
per cent, along with the 3.6
per cent gain in per capita :
consumer income. The volume
of food consumed per person
in 1962 was about the same
as in 1961. with gains in
meals and fats and oils offset
by declines in the consump
tion of dairy products and
fresh fruits and vegetables, j
The department predicted ,
total consumer expenditures
for food in 1963 likely will in
crease but probably not as
much as the 4 per cent in-'
crease in 1962. Per capita con
sumption of food may increase
a little this year, particularly
consumption of meals and i
poultry. i
Little Change Seen
The department expects lit
tle, if any. change in the all
food price level for the year
as a whole, compared with
1962.
Exports of foods last year
are estimated to have been
near the record-large quantity
exported in 1961. They were
especially strong for fats and
oils, while grains decreased
some. Early in 1963, food ex
ports were slowed by the
shipping strike, but with ship
pins moving again, these ex
ports will increase. There are
ample supplies to take care
nf domestic needs and still al
low large exports.
