Is there any evidence that glycerol is metabolized at cryothermic temperatures? As far as I'm aware, glycerol toxicity in cryobiology is due to the direct action of glycerol itself. Of course this may all be academic given the renewed interest in non-glycerol CPAs inspired by Visser. None of the most promising organ cryopreservation technologies now use glycerol. Glycerol's days in cryonics are clearly numbered. *************************************************************************** Brian Wowk CryoCare Foundation 1-800-TOP-CARE President Human Cryopreservation Services http://www.cryocare.org/cryocare/ --------------------------------------------------------------------------- Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=6991
