LifeTECH Scientific Abstract to be Present at International 
Society for Antiviral Research Conference

TORONTO, April 10 1997 - LifeTECH Corporation today announced the 
acceptance of a key scientific abstract at the International 
Society for Antiviral Research Conference to be held on April 10, 
1997 in Atlanta, Georgia. The abstract is entitled "Inactivation 
of Enveloped and Non-Enveloped Viruses by Ozone Induced Oxidative 
Stress." Its principal author is Dr. Peter Lea, LifeTECH's 
Director of Research and Development. 

The announcement was made by Mr. Walter J. Dermott, President & 
CEO, who said "The acceptance of another LifeTECH abstract at an 
important international congress reflects the rapid pace of our 
scientific advances. The unique ability of our Sterinetics(TM) 
System to inactivate viruses in blood and blood products has now 
been recognized by scientific symposiums around the world. Our 
research and development will position the Sterinetics System as 
the only viable sterilization technology that can make the global 
blood supply safer."

The abstract describes the dramatic progress achieved by the 
Sterinetics System in the sterilization of blood and blood 
products. LifeTECH's research has confirmed the successful 
inactivation in human immunoglobulin of 6 logs/ml of two enveloped 
viruses - Infectious Bovine Rhinotracheitis, a large herpes virus 
and Bovine Viral Diarrhea, which models the human Hepatitis C 
virus - and Bovine Adenovirus, a non-enveloped virus. Of critical 
importance was the finding that the human immunoglobulin was fully 
functional after the application of controlled oxidative stress, 
verifying its suitability for transfusion purposes.

The International Society for Antiviral Research is based in the 
Janssen Research Foundation, Beerse, Belgium and provides an 
interdisciplinary forum for scientific investigators involved in 
basic, applied and clinical research in all areas of antiviral
