LifeTECH Abstract on Viral Inactivation in Human Red Blood Cells 
to be Presented at Experimental Biology '97 Conference


TORONTO, April 8 1997 - LifeTECH Corporation today announced the 
acceptance of a scientific abstract describing innovative viral 
inactivation in human red blood cells by the Sterinetics(TM) 
System. The abstract, entitled "Virus Inactivation in Human Red 
Blood Cells by Induced Oxidative Stress", will be presented at the 
Experimental Biology '97 conference to be held April 6-9, 1997 in 
New Orleans. Principal author of the abstract is LifeTECH 
scientist Dr. Lilian Lee.

Walter J. Dermott, President & CEO, made the announcement, saying, 
"Our research dramatically advances the science of inactivating 
viruses in human red blood cells. The unique ability of the 
Sterinetics System to inactivate 6 logs/ml of Bovine Viral 
Diarrhea Virus (BVDV) in red blood cells once again raises the bar 
for the competition. Our scientists have also developed important 
new methods for quantifying viral inactivation, as well as 
identifying assays to validate red blood cell structure and 
function after controlled oxidative stress. The Sterinetics System 
continues to be the only viable sterilization technology that can 
make blood transfusions safer for all."

The abstract, Number 341/2981, describes the inactivation of three 
key viruses in human red blood cells: Bovine Viral Diarrhea 
(BVDV), an enveloped virus which models the human Hepatitis C 
virus; Infectious Bovine Rhinotracheitis (IBR), a large enveloped 
herpes virus; and Bovine Adenovirus, a non-enveloped virus that 
causes respiratory diseases in humans and bovine species.

Experimental Biology '97 is a biomedical scientific meeting 
coordinated by The American Physiology Society, the American 
Society for Investigative Pathology, the American Society for 
Nutritional Sciences and the American Association of Anatomists. 
More than 8,000 scientists are expected to attend the newest 
scientific concepts and experimental results from around the 
world.
