These experiments are exactly why people were excited about cryonics, until they realized that it doesn't work on anything much larger than a rat.

You have to thaw them right down to the core very quickly; you need to get the heart pumping or the thawed extremities will die with no bloodflow. There's no way to heat a human's core that fast without causing unsurvivable burns to their outside. (Even the rats wound up with nasty, sometimes fatal burns.)
