Abstract:
The scrota and testes of the rabbits were exposed to 2450 mHz microwave field and the temperature of scrotal skin was raised to 41-42℃ for 20 minutes. Ultrastructural observations on the peritubular tissue of ductus epididymides were studied at different intervals from 30 minutes to 4 months after the treatment, and alkaline phosphatase cytochemical changes were observed at intervals from 12 hours to 30 days. Pronounced morphological alterations of the smooth muscle cells and endothelial cells of capillaries were detected within 30 minutes to I hour following exposure. After 24 hours to 3 days, the thickening of the peritubular tissue were noted. The thickening and infolding of the proper lamina were also prominent. The degenerative smooth muscle cells generally returned to normal appearance after 3-4 months, but the thickening of the peritubular tissue and infolding of the proper lamina still appeared. Alkaline phosphatase was localized in the basal lamina, proper lamina, the innermost smooth muscle cells cytoplasm and surface vesicles. There were no obvious alterations of alkaline phosphatase activity after 12 hours. After 15 days, the alkaline phosphatase prominently decreased, while after 30 days the alkaline phosphatase increased nearly to normal.
