X-Message-Number: 7737 From: (Thomas Donaldson) Subject: Re: another tech question Date: Sun, 23 Feb 1997 10:27:41 -0800 (PST) Hi again! After sending my last questions about fluorocarbon cooling, I thought of another one: presumably this process also involves infusion of a cryoprotectant (CP). Ignoring just which CP this may be (possibly an important question), is the CP also dissolved in the fluorocarbon solution? If it is not, then do you get a problem with its REMOVAL as you circulate the solution? And if you do get such a problem, it may or may not be serious (perhaps --- speculating: once the temperature is low enough and you have the fluorocarbon in the brain, the CP is no longer necessary). Regardless, these results still look very good so far. Long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=7737
