四氯化碳对雄性小白鼠生殖细胞染色体畸变率的影响

THe Effect of Carbon Tetrachloride on Gierm Cell Chromonema Aberration Rate in Male Mice

选用小鼠睾丸染色体畸变试验探讨四氯化碳 ( CCl4)对生殖细胞染色体的诱变作用 ,结果表明 ,16～ 8mg/ kg体重的四氯化碳可不同程度地诱发小鼠睾丸精母细胞染色体畸变 ,畸变率 ( %)分别为 31.2± 4.2 3与 2 5 .2± 4.34。

The mice testes was wsed as the material to study the chromonema aberration of gern cell by carbon tetrachloride.The spermatocyte chromonema aberration in mice tertes was found when treated by 16 mg/kg carbon tetrachloride in different degree the aberration rates were 31.2±4.32 and 25.2±4.34 respectively.Which indicated that carbon terachloride could induced geren cell chromonema aberration in marmmal and it was a kind of mutagen.
