X-Message-Number: 16578 Date: Mon, 18 Jun 2001 13:44:24 -0400 (EDT) From: Charles Platt <> Subject: 21CM Ice Blocker as an Additive In a previous post I stated that 21CM's ice blocker can be used in conjunction with "existing protocol." What I should have said is that the ice blocker can be used in conjunction with the type of conventional glycerol solution that is used in existing protocol--PROVIDED THAT the glycerol reaches a high terminal concentration in the perfused tissues. Since the terminal concentration reported by Robert Ettinger on Cryonet some months ago is really quite low, CI would need to upgrade its perfusion capability before it could profitably add the ice blocker. This is pretty much what Ben Best said in his post. One can reach two conclusions from these statements. Either it's pointless for CI to experiment with the ice blocker; or CI might consider improving its perfusion technique to reach a higher terminal concentration, so that the ice blocker could be used to provide greatly enhanced protection for its patients. --CP Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=16578
