摘要
目的观察棓丙酯对四氯化碳导致的肝纤维化大鼠的保护作用,为临床治疗肝纤维化提供实验依据。方法以四氯化碳皮下注射复制大鼠肝纤维化模型,设立正常对照组、肝纤维化模型组和棓丙酯组,棓丙酯组在造模的同时给予棓丙酯注射液皮下注射。6周后取肝组织常规HE染色观察肝脏病变,天狼猩红胶原染色、肝组织羟脯氨酸(HYP)含量测定观察肝纤维化程度;赖氏法测定血浆丙氨酸氨基转移酶(ALT);TBA法检测肝组织丙二醛(MDA)水平,产色基质偶氮法鲎试剂定量测定血浆内毒素。结果棓丙酯与肝纤维化模型组比较,①肝脏的损伤性改变较轻,肝组织HYP及肝纤维化指数(FI)明显降低。②血浆内毒素含量、ALT及肝组织MDA均有不同程度的降低。结论棓丙酯具有一定的抗肝纤维化的作用。
Objective To explore the effects of propylgallate on hepatic fibrosis in rats. Methods Hepatic fibrosis in rats was induced by carbon tetrachloride, 24 rats were randomly divided into normal control group, hepatic fibrosis group and propylgallate group, propylgallate group rats were given propylgallate subcuta- neously while inducing hepatic fibrosis by carbon tetrachloride. Rats were killed for collecting blood and liver tissues in 6 weeks. The pathological changes were observed by hematoxylin-eosin staining, the degree of liver fi- brosis was observed by stained of Sirius red for collagen and the contents of hydroxyproline in liver tissues. Plas- ma alanine aminotransferase （ALT） was determined with Reitman-Frankel method; the content of malondialde- hyde （MDA） in liver tissue was determined with TBA method. Endotoxin in blood plasma was measured with a limulus ameboeyte lysate test kit. Results Propylgallate group compared with the hepatic fibrosis model group： ① fibrotic changes in liver were ameliorated, hydroxyproline in liver tissue and hepatic fibrosis index were sig- nificantly reduced. ②Plasma endotoxin, ALT and liver MDA were reduced as well. Conclusion Propylgallate has significant protective effect on liver fibrosis in rats induced by carbon tetrachloride.
