X-Message-Number: 15403 From: Date: Sun, 21 Jan 2001 12:01:13 EST Subject: CI procedures again Thomas Donaldson (#15393) shows again that sometimes he just doesn't pay attention. He has shown this repeatedly in his go-rounds with Mike Perry, but I won't get into that here. Thomas mentioned "secretiveness" and wrote, in part: >it may well clear the air if we can learn just what the [Cryonics] Institute's current >methods may be, especially since they recently did some suspensions. CI current methods (which will almost certainly be improved this year) are on record in several places including our web site--in particular, on our research page with Dr. Pichugin's report of his repetition of our sheep head work and its evaluation. And on our page "Comparing Procedures and Policies" are some extensive explanations of why we do or don't do certain things. I suggest careful readings of these pages by anyone in doubt. It seems pretty clear that newcomers, by and large, find our disclosures and explanations satisfactory. People tend to "vote with their feet," and CI growth has been faster than anyone else's in the last couple of years. No amount of fulminating on Cryonet can change that. Nevertheless, there may be some who don't get an impression of clarity, and we always try to improve, so we will shortly modify the web site pages to include a clearer and more succinct summary of our procedures. But let me emphasize again--exactly what is it that Thomas, or anyone else, would gain from ever more detailed explanations of our procedures? Would you compare that information with reports in the cryobiological literature and make a theoretical guess as to whether our methods conform to "accepted" views of what is best for brains? Would you actually go to the trouble and expense of replicating our work, or paying someone else to do it, and then paying for its evaluation by independent professionals? Is it not obvious that the bottom line is RESULTS? Two sets of independent professionals have evaluated our work, and key parts of the reports are on our web site. They show clearly that (1) our procedures (one pass with 75% glycerol) produce much less damage than is observed in untreated controls, and (2) ours are better than using stepped glycerol with a lower (30%) maximum concentration, and (3) with some tissues, by a very slight margin, there may be a better result with stepped glycerol with the same maximum concentraton (75%). The second lab, run by someone on the faculty of a Canadian university, did not know how the specimens had been prepared, so could not have been biased. Is there anyone--any newcomer especially, but also anyone else, including Thomas--who would rather bet on his own theoretical guesses than on actual professional evaluation of results? Suit yourselves. Now again, how about the latest Alcor procedures? Key parts are admittedly secret, at least for the time being--not by inadvertence or lack of clarity, but by policy, for commercial reasons. Of course, that aspect is legal and defensible. Less defensible is Fred Chamberlain's over-reaching in his article in CRYONICS and on their web site, "Vitrification arrives!" The decision itself--to use the new procedures--is defensible, and it may have been the right decision. But we don't know, whereas the thrust of the article is to convey the impression that we do know. The fact is that the new procedures, as applied to Alcor's last two patients, have never been tested and evaluated, as far as I know--not by anyone, at any time, anywhere. Instead, scattered and partial and indirect evidence has been used to create the impression that the decision was based on direct evidence. As I have said, critics of CI in most cases, asking for more details, probably just want to score debating points, not to test our methods for themselves. We on the other hand, in desiring more information about the Alcor methods, truly do want to test their methods ourselves, and we will pay for professional evaluation of those tests, if those methods are still relevant when we get the information.
