目的　实验观察三乙醇胺染毒后实验动物的组织病理学改变。方法　 32只实验大鼠分别染毒不同剂量的三乙醇胺 (2 50 ,50 0 ,750 mg/kg) ,每周 1次 ,7周后断头处死进行大体解剖和组织病理学检查。结果　 50 0 ,750 mg/kg染毒组脏器系数增大 ,肝、脾、肾等器官有细胞水肿和嗜酸性变等不同程度的病理学改变。结论　接触一定量的三乙醇胺对大鼠肝、脾、肾脏组织有损伤作用 Objective To observe the histopathological changes of experimental animals after triethanolamine exposure. Methods Twenty-two experimental rats were treated with different doses of triethanolamine (2 50, 50 0, 750 mg / kg) once a week for seven weeks and then sacrificed for gross anatomy and histopathology. Results 50 0, 750 mg / kg increased organ coefficient of rats, liver, spleen, kidney and other organs with varying degrees of cellular edema and eosinophilic pathological changes. Conclusion Exposure to a certain amount of triethanolamine can damage the liver, spleen and kidney of rats
