[The action of microwave radiation on potassium ion transport and oxygen consumption in the perfused rat liver].

Changes induced by the effect of microwave irradiation (2450 MHz, specific absorbed power from 0.1 to 5 W/g, continuous and pulsed-modulated regime) on potassium ion transport and oxygen consumption in the perfused liver do not virtually differ from those induced by heating the perfusate: this is indicative of a "thermal" mechanism of action of microwave radiation.
