We consider the problems arising when freezing and defrosting the biotissues. The article emphasizes the urgency of the issue and the statistical estimate of the people with cold-related injuries for the period from 1 January to 13 February 2017. It examines the processes of insult to cells under different speeds of freezing and defrosting by means of the most commonly used up-to-date techniques and shows their inefficiency. We suggest a new treatment mode for severe tissues injuries caused by low temperature impact on the organism. The work analyzes the characteristic features of the microwave wavelength absorption process in the living tissue under the hypothermia conditions and leads out the mathematical model of this process. The article elicits and justifies the viability of warming-up the partially frozen bioobject in the microwave field.
