2、叶毒性和进行毒性比较。结果在急性毒性实验中,各给药组小鼠无死亡;小鼠骨髓微核实验中和精子畸形实验中,各给药组与正常组无统计学差异。大鼠30d喂养实验中,厚朴叶对大鼠的食物利用率、血常规、肾功能都有所影响,也影响肝、卵巢、睾丸的脏体系数;在对大鼠各脏器病理组织学检查中未见明显异常;厚朴叶与厚朴皮、厚朴花的慢性毒性差异为后两者不影响血常规。结论厚朴叶无急性毒性,无致骨髓突变毒性,无致精子畸形毒性;厚朴叶有慢性毒性作用,表现在影响食物利用率、血常规、肾功能、器官发育;厚朴叶与厚朴皮、厚朴花的毒性差异表现在慢性毒性中影响血常规,其它无差异。关键词:厚朴叶;厚朴皮;厚朴花;毒性比较中图分类号:R28
