[Histological signs of thermal damaging by electricity].

Identification of histological signs of thermal damaging by electricity. It was studied the histological picture of the electrometric and changes in the epidermis and dermis in the area of exposure to a red-hot metal object. The same type of microscopic changes in the skin have been revealed: in the central zone of damage there were coagulation necrosis and homogenization, as well as the porous tissue structure formation; in the peripheral zone there were deformation of cells with their verticalization and the vortex figures formation. These histological signs are a manifestation of coagulation processes, hydrodynamic effects because of explosive boiling of interstitial fluid and tissue deformation that characterize the thermal damaging effect. The data obtained clarify the mechanism of the damaging effect of technical electricity on human tissue.
