For the first time solid evidence linking
the
incurable disease multipie^ selerosis with an infectious
virus
has been found by reseachers in New York and Pennsylvania. The
malady attacks the brain and the spinal cord. Symptoms casually
appear in victims in their 30 1 s. Speech becomes slurred. The
eyeballs flick up and down and back and forth. Gradually
the
victim loses eye sight and becomes progressively paralyzed.
Only in the last few years have scientists found clues to what
causes MS.
In 1972 , Dr. R. I. Carp and colleages at the Institute
of Research on Mental Retardation, Staten Island, injected mice
with material from the brain and other tissues of MS patients
and discovered a resultant drop in the white blood cells - a
sign of virus infection. They also found that the viral
agent
multiplied in the brains of test animals and could be transmitted
from mouse to mouse. Now, a husband-and-wife team, Drs. Werner
and Gertrude Henle, in Philadelphia, has confirmed the presence
of this virus in similar tests with rats, hamsters and
guinea
pigs. They also detected the virus in the blood of MS patients.
