[Combined action of a UHF electromagnetic field and local freezing on biological tissues]

Experience gained so far by cryogenic surgery indicates that the possibilities of cryodestruction of sizable pathological formations are fairly limited. To overcome this barrier, it is necessary to change the status of the tissues, making them more sensitive to cryodestruction. The theoretical investigations suggest that microwave irradiation is one of the factors capable to change the status of tissues and to raise their sensitivity to cold exposure. Experiments made on the liver and muscles from rabbits, dogs and guinea-pigs have demonstrated that preliminary microwave irradiation followed by local freezing promotes the death of tissues 4-6-fold as compared to control.
