The researchers said these cells
appear to be at work in several pa
tients who have been infected with
the virus for up to four years.
These patients either have not
gotten AIDS or, if they already were
infected, their disease seems to be in
remission.
If the suppressor T-cells prove to
control the virus in humans, the re
searchers said, it may be possible to
boost the number of these cells to
stop the virus from reproducing and
arrest progress of AIDS.
“This is the first indication that in

of controlling the virus,” Levy said in
a telephone interview. “This discov

[ATLANTA (AP) — Almost
DO previously unexplained
IDS cases have been reclassified
heterosexually transmitted,
publing the percentage to 4 per-
nt of such cases, government
searchers said Thursday.
By 1991, one researcher said,
pterosexual cases could make up
Karly 10 percent of AIDS cases.
■ The national Center for Dis-
■se Control also reported that
■e AIDS case count in the
United States stands at 28,098,
■ice the number reported 13
mths ago. Fifty-six percent of
|e victims are dead.
The CDC said it now can re
classify 571 AIDS cases — all in
apparently heterosexual, non
drug-using people who were
born outside the United States in
areas such as Haiti and central
Africa, where heterosexual con
tact is the chief way of spreading
the disease.
Evidence indicates heterosex
ual transmission in those cases,
the CDC said, because some of
the patients have other sexually
transmitted diseases and because
some male AIDS patients report
edly have been with prostitutes.
person’s own immune cells rather
than drugs that are toxic to the body.
“The drama of this observation is
that we are finding people who are
antibody-positive, meaning they are
infected, and we can’t get virus from
their blood and they seem to im
prove all by themselves.
“We now have a mechanism that
could explain this.”
The AIDS virus attacks another
group of T-cells, called helper T-
cells, which govern the other compo
nents of the immune system.
The virus penetrates the helper
T-cells, reproduces, and destroys its
host cells as it spreads to other cells.
In this way, the AIDS virus, va
riously known as HTLV-3, HIV or
LAV, cripples the disease-fighting
immune system, leaving sufferers
vulnerable to numerous infections
and cancers that lead to death.
More than 28,000 Americans
have been diagnosed with the incur
able infectious disease, half of whom
have died.
Levy, with Drs. Christopher
Walker, Dewey Moody and Daniel
Stites, found that suppressor T-cells,
whose normal job is controlling the
production of antibodies by other
cells, appear to emit an unknown
substance that keeps the virus from
reproducing after invading the
helper cells.
When certain suppressor T-cells
that have a protein on their surface
called CD8 were removed from
blood cultures, the virus started to
grow in the remaining blood cells,
the scientists reported.
But when the suppressor T-cells
were put back into the cultures, re
production of the virus was sup
pressed, they said.
The suppressor cells do not de
stroy the virus or kill the host cells.

decision upheld the Nov. 15
Ision by the three-member Peo-
Revolutionary Tribunal con
ing Hasenfus of helping to airlift
_B)ons to U.S.-backed Contra re
els.
[This is the definitive sentence
ati has been decided,” the head of
the three-member appeals court, Ar-
wengol Cuadra Lopez, said after the
ruling was read. “The defendant,
Eugene Hasenfus, must serve the
maximum penalty of 30 years.”
The People’s Revolutionary Tri
bunal, made up of a lawyer, a truck
driver and a laborer, found Hasen
fus guilty of violating public order
and security, criminal association
and terrorism.
The case was reviewed automat
ically by the higher court, known as
the Superior People’s Revolutionary
Tribunal. The higher court was
composed of Cuadra, who is a law
yer, and a carpenter and a clerk.
The tribunal system, which is out- *;
side the regular law courts, was cre
ated by the Sandinista government
to try those defendants considered
counterrevolutionaries.
Hasenfus, 45, of Mariette, Wis.,
was captured Oct. 6, one day after a
plane ferrying weapons to the Con
tras was shot down by army troops in
southeastern Nicaragua. He was the
only survivor out of a crew of four.
