CI RESEARCH FORGES AHEAD
Dr. Yuri Pichugin's vitrification research continues gradually to yield new information and improved results. In recent work he has been able to keep brain slices at dry ice temperature for 48 hours, with viability as good as before cooling, namely, around 75% by the potassium/sodium criterion.
Also, two liters of the latest vitrification mixture was kept at dry ice temperature for 72 hours, with no ice crystallization.
So, according to all the results it is possible to keep a patient’s body at dry ice temperature at least for 48 hours without ice crystallization and without reduction of tissue viability.
Additional information has also been obtained pertaining to the rate of absorption of the vitrification mixture.
Work with whole animals has yet to begin.
