摘要
目的 :研究乌索酸保肝利胆作用。方法 :分别以CCl4、APIT制作动物急性肝损伤模型 ,测定血清ALT、AST、SB含量 ,作肝组织病检 ,观察乌索酸对动物急性肝损伤的影响 ;采用麻醉大鼠行胆汁引流术 ,测定正常大鼠及APIT肝损伤大鼠的胆汁分泌量及胆汁成分。结果 :乌索酸能明显降低CCl4、APIT急性肝损伤动物血清ALT、AST水平及SB含量 ,减轻肝组织病理损伤 ;使正常大鼠、APIT肝损伤大鼠的胆汁流量明显增加 ,胆汁中胆红素浓度提高。结论 :乌索酸有明显保肝、利胆作用。
Objective: To study the liver protection and promoting bile secretion of ursolic acid Methods: Ursolic acid was administrated to the mice with liver injury induced by CCl 4 or APIT ALT, AST levels in serum were examined The bile flow rate and the concentration of the main components in the bile of rats administrated with ursolic acid were estimated Results: Ursolic acid could decrease the serum ALT, AST, SB levels in the mice treated with CCl 4 or APIT, promote the secretion of bile and increase the concentration of bilirubin in the bile Conclusion: Ursolic acid exhibited significant liver protection and promoting blie secretion
