单纯三硝基甲苯(TNT)染毒动物组和单纯紫外线辅射组动物白内障发生率分别为28.6％和33.3％。TNT染毒加紫外线照射组为57.1％,发病率增加近1倍。光镜和电镜观察,TNT染毒加紫外线照射组动物晶状体组织结构病理改变明显重于上述两组。可以认为,紫外线和TNT两种有害因素共存时,对白内障的发病有协同作用。
The incidence of cataract in animals exposed to TNT alone and UV alone was 28.6% and 33.3%, respectively. TNT exposure plus UV irradiation group was 57.1%, the incidence increased nearly 1 times. Light microscopy and electron microscopy, TNT exposure and UV irradiation of the lens tissue pathological changes were significantly heavier than the above two groups. It can be considered, UV and TNT coexistence of two harmful factors, the incidence of cataracts have a synergistic effect.
