为研究维生素E对铬酸钾 (K2 CrO4 )所致大鼠睾丸毒性的影响 ,将大鼠分为 4组 ,其中 3组口服K2 CrO4 (1 0mg/kg体重 ) ,第二组加服维生素E(5mg/kg) ,第三组按 2 0mg/kg体重加服生素E ,连续服药 30天 ,通过光镜检查 ,结果发现 :单独服用K2 CrO4 1 0mg/kg组的大鼠睾丸曲细精管不同程度变性 ,管内生精细胞数目减少、缺如 ,精子形成少或者无。而用K2 CrO4 (1 0mg/kg)染毒同时加服维生素E(2 0mg/kg)组大鼠睾丸组织破坏程度减轻。结果显示 :维生素E在一定程度上能拮抗铬的毒性 In order to study the effect of vitamin E on testicular toxicity induced by potassium chromate (K2 CrO4), rats were divided into 4 groups, of which 3 groups were orally administered K2 CrO4 (10 mg / kg body weight) and the second group served with vitamin E (5mg / kg), the third group by 20mg / kg body weight plus vitamin E, continuous medication for 30 days, by light microscopy, the results showed that: taking K2 CrO4 10mg / kg group of rat testicular seminarin Tubules of varying degrees of degeneration, the number of spermatogenic cells decreased, absent, less or no sperm formation. However, the damage of testicular tissue in rats treated with K2 CrO4 (10 mg / kg) and vitamin E (20 mg / kg) was alleviated. The results showed that: vitamin E to a certain extent, can antagonize the toxicity of chromium
