[Effect of microwave radiation on regional blood flow and tissue oxygenation in the brain].
The effect of irradiation of the central nervous system by microwaves (MW) at a frequency of 2450 MHz and power 5-40 W on the regulation of cerebral circulation and oxygen supply to the nervous tissue were studied in rabbits. Local irradiation of the exposed cerebral cortex resulted in hyperemia and hyperoxia in the zone of exposure induced by the hyperthermal effect of MW. When the region of the medulla oblongata was irradiated even with low MW power (not leading to hyperthermia), the local circulation and oxygen tension increased in the whole brain, apparently due to the impairment of the regulation of the cerebral blood flow and oxygen supply to the brain tissue.
