Abstract
To investigate the mechanism of effects of microwave irradiation on the central nervous system, 12 male LACA mice were irradiated with 3000-MHz microwave 1 h daily for 7 days at incident power density of 5 mW/cm2. Significant inhibitory effects were observed on total electroencephalic energy and peak electroencephalic energy of left and right central concatenated electrodes (channels 3 and 4) as compared to the control (p < 0.05 and/? < 0.01, respectively). It was also discovered that the adenosine triphosphate (ATP) in the brain and the amounts of succinate dehydrogenase (SDH) in the hypothalamus and hippocampus were reduced significantly in the irradiation group as compared to the control (p < 0.05). The mechanism might be as follows: the decrease in SDH causes the decrease in ATP, and then a lower ATP possibly results in lower electroencephalic energy. It is thus suggested that effects of microwave irradiation on central nervous system are relevant to electroencephalic energy.
