X-Message-Number: 12466 From: Thomas Donaldson <> Subject: to Doug Skrecky Date: Tue, 28 Sep 1999 23:30:35 +1000 (EST) To Doug Skrecky: Fine. You say that brains have been completely embalmed ie. the substance penetrated at the right concentration into the entire brain. Please give a reference for this. (I'm not doubting you, I just want to look at the subject past what you say). I know of lots of cases in which various fixatives have been used on pieces or slices of brain; I'd like a case in which the entire brain became PROVABLY fixed. This leaves the issue of revival open (except perhaps for red blood cells). One problem with such methods is that they may unwittingly destroy some essential chemical. I'd be interested in any discussion you can make about that. Second, ideas about how to look into means to revive such tissue (rather than simply putting the problem off into some unknown future) would also be useful. The rest of what you say in your reply I do not doubt and would even agree with. I am asking about fixation and fixation methods; once we have the problems with such methods solved (or see a way to solve them, even if it will take some time) the other treatments shouldn't prove questionable. Best and long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=12466
