摘要 目的:评价治疗良性前列腺肥大的新药依立雄胺(Epr)的遗传影响.方法:1)鼠沙门氏菌体外回复突变试验测试能否诱发基因突变;2)CHL细胞染色体的损伤和畸变实验;3)ICR小鼠一次igEpr后测试是否导致骨髓嗜多染红细胞染色体的损伤;4)昆明种小鼠连续igEpr5d,30d后统计精子头部异常情况.结果:1)Epr不诱导细菌回复突变.2)CHL细胞染色体畸变低于3%不造成细胞染色体损伤.3)Epr不诱导小鼠嗜多染红细胞微核的形成.4)Epr高、中、低剂量组引起的头部畸形率分别为5.3%±2.7%,5.3%±1.9%,5.2%±1.2%,与对照组相比不引起显著的精子头部异常.结论:Epr在体内外实验中没有表现出遗传毒性.
