Abstract

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.

摘要

研究了2450兆赫频率、5 - 40瓦功率的微波(MW)对家兔中枢神经系统的照射,对脑循环调节及神经组织氧供应的影响。对暴露的大脑皮层进行局部照射,由于微波的热效应,在照射区域导致充血和高氧。当即使使用低微波功率(不会导致体温过高)照射延髓区域时,全脑的局部循环和氧分压增加,这显然是由于脑血流调节和脑组织氧供应受损所致。
