A May 4 press release on the Telescan System which monitors 
various small-cap stocks, relates to BioTime Inc.(NASDAQ-listed as 
BTIM), a company which produces artificial blood substitutes currently 
under review for approval by the FDA. Their research vice president, Dr. 
Hal Sternberg, describes "experiments in which hamsters were completely 
blood substituted at hypothermic temperatures with BioTime solutions, 
and then placed in sub-zero freezing baths for periods of up to 2 hours. 
These animals reached deep body temperatures as low as -4 C, and then 
were revived to consciousness and reactivity. An analysis of brain 
tissue immediately following revival indicated that substantial freezing 
and thawing of the tissues of the brain had occurred. Sternberg said, 
'these experiments reveal that mammals can survive - at least for short 
periods - partial freezing of vital organs, if their blood is replaced 
with solutions which guard against some of the damage caused by ice 
crystallization.'
	No mention is made of the implications for cryonics, but it 
would seem like this is non-trivial forward progress. Any comments?
