本文用微波(2450mHz)照射兔阴囊,使阴囊皮肤温度升至41～42℃,维持20min。用电镜观察照射后30min至4个月之间不同时间阶段附睾中段的附睾管周组织超微结构改变,同时还观察照射后12h至30d之间不同时间阶段,对附睾管周组织内碱性磷酸酶细胞化学的影响。照射后1/2～1h,即见平滑肌细胞和毛细血管内皮细胞呈现明显的形态学改变。24h～3d后,小管周组织增厚,其中的固有膜增厚内凸明显。3～4个月后,平滑肌细胞一般已恢复正常形态,但小管周组织的增厚和固有膜的内凸仍然存在。碱性磷酸酶分布于基膜、固有膜、最内层平滑肌细胞胞浆及其表面小泡。照射后12h碱性磷酸酶活动无明显改变,15d后明显减少,30d后接近正常。
In this paper, microwave irradiation (2450mHz) rabbit scrotum, scrotal skin temperature rose to 41 ~ 42 ℃, maintaining 20min. The ultrastructure of epididymal peri-epididymis was observed by electron microscope at different time points between 30min and 4months after irradiation. At the same time, the changes of alkaline phosphatase Effects of enzyme cytochemistry. After irradiation 1/2 ~ 1h, that smooth muscle cells and capillary endothelial cells showed obvious morphological changes. After 24h ~ 3d, the peritumoral tissue thickening, in which the intrinsic thickening of the intrinsic membrane obvious. After 3 to 4 months, the smooth muscle cells generally returned to their normal shape, but the thickening of the peritubular tissue and the convexity of the intrinsic membrane still exist. Alkaline phosphatase distributed in the basement membrane, lamina propria, the innermost smooth muscle cell cytoplasm and its surface vesicles. Alkaline phosphatase activity did not change significantly at 12h after irradiation, but decreased significantly after 15d, and nearly normal after 30d.
