[Study of the state of mitochondria at low temperatures by the ESR method]

Possible usage of ESR probe method for studying low temperature effect on structural and functional state of mitochondria is under study. It is shown that during freezing out of mitochondrial water there is sharp dehydration of intermitochondrial matrix and membrane thickening. The facts are given about damage of barrier function of the membrane at the moment of appearance of extramitochondrial liquid phase during thawing.
