	Yes, you are always walking a tightrope between perfusate
toxicity (which is temperature dependent) and the prevention of
freezing (ice formation).  Sophisticated computer-controlled perfusion
technology has been developed for introducing and removing  
perfusate according to a precise temperature/time schedule.
It appears to be working well enough to allow recovery of
whole kidneys from -40'C, as Mike as described.
