摘要：目的 观察三苯氧胺(TAM)对小鼠内脏器官的形态影响。方法 以不同剂量的TAM(0.02mg·kg-1·d-1、0.2mg·kg-1·d-1、2mg·kg-1·d-1)分别连续灌胃染毒小鼠35天，于末次染毒称取体重后处死小鼠，取出心、肝、肾等器官，称重，光镜下观察病理形态变化。结果 高剂量组与阴性对照组比较，肝/体系数差异有显著性(P<0.05)，部分肝细胞可见脂肪变性。心、肾脏体系数与阴性对照组比较差异无显著性，光镜下无形态异常。结论 部分肝细胞脂肪变性可能与长期服用TAM有一定的关系。关键词： 三苯氧胺； 脂肪变性；病理形态学

ABSTRACT：Objective To observe the effects of tamoxifen(TAM)on the internal organ of mice. Methods TAM was administrated to mice at different doses(0.02mg·kg-1·d-1,0.2mg·kg-1·d-1,2mg·kg-1·d-1)by gavage once a day for successive 35 days. The mice were weighted and sacrificed on the 35th day . The hearts, livers and kidneys were enucleated and weighted. The pathomorphologic observation were made by light microscope . Results The ratio of liver /body had significant difference between 2mg·kg-1·d-1 groups and negative control group (P<0.05). The liver cells with fatty degeneration were observed in 2mg·kg-1·d-1 and 0.2mg·kg-1·d-1TAM groups . The ratio of heart and kidney to body had no significant difference with those in negative control group. Conclusion Hepatic steatosis may occurred after lasting taking TAM. ......
