Summary

1,3-BUTANEDIOL AND 2,3-BUTANEDIOL HAVE BEEN USED IN BUFFERED SOLUTIONS WITH 20, 30 OR 35% (W/W) ALCOHOL TO COOL ERYTHROCYTES TO 77 K (-196 DEG C) AT DIFFERENT COOLING RATES BETWEEN 0.017 AND 58 K/SEC FOLLOWED BY SLOW OR RAPID REWARMING. 1,3-BUTANEDIOL SHOWS THE SAME SHAPES OF RED BLOOD CELL SURVIVAL CURVES AS 1,2-PROPANEDIOL. THE CLASSICAL MAXIMUM OF SURVIVAL FOR INTERMEDIATE COOLING RATES AND AN INCREASE FOR THE HIGHEST COOLING RATES ARE OBSERVED WHICH SEEMS TO BE CORRELATED WITH THE GLASS-FORMING TENDENCY OF THE SOLUTION. AFTER THE FASTEST COOLING RATES, A WARMING RATE OF 83 K/SEC IS SUFFICIENT TO AVOID CELL DAMAGE, BUT A WARMING RATE OF 1.7 TO 3.3 K/SEC IS NOT.
