RESUMO
Objective: To observe the effects of microwave on the activity of SOD and the contents of MDA in renal cortex and testis of mice. Methods: Microwave generator(2 450 MHz, 10 mW/cm2) was used to expose mice; NBT,DTNB and TBA were used to mearure the activity of SOD and the contents of MDA in renal cortex and testis of the mice after microwave exposure.Results: The content of MDA in renal cortex and testis of the mice increased progressively on days 1,6,12 and reached the highest level on day 24 after the microwave exposure (P<0.01). The activity of SOD in renal cortex and testis of the mice decreased progressively on days 1, 6, 12 and reached the lowest level on day 24 after the microwave exposure (P<0.01). Conclusions: Microwave exposure can produce reactive oxygen free radicals and lead to depress SOD activity.
