丹酚酸A抗四氯化碳中毒致大鼠肝损伤和肝纤维化的作用

目的：研究丹酚酸Ａ（ＳＡ－Ａ）抗肝损伤、肝纤维化作用。方法：采用ＣＣｌ４诱导大鼠肝损伤及肝纤维化，期间予ＳＡ－Ａ灌胃治疗，另设秋水仙碱（Ｃｏｌ）组、丹参组作对照，６周后进行肝组织病理学和Ｉ、Ⅲ型胶原免疫组化观察，肝组织羟脯氨酸（Ｈｙｄ）、丙二醛（ＭＤＡ）含量及血清ＡｌａＡＴ、ＡｓｐＡＴ和白蛋白含量测定。结果：ＳＡ－Ａ降低血清ＡｌａＡＴ、ＡｓｐＡＴ水平及肝组织ＭＤＡ、Ｈｙｄ含量，减轻肝纤维化程度，抑

Actions of salvianolic acid A on CCl4-poisoned liver injury and fibrosis in rats]

AIM: To study the actions of salvianolic acid A (SA-A) on liver injury and liver fibrosis. METHODS: The liver fibrotic rat was made by i.p. injection of CCl4. The model rats were divided into 3 groups treated with SA-A, colchicine (Col), and Salvia miltiorrhiza Bunge (SMB), respectively. Six wk later the rat liver pathology was examined, type I and III collagen in the liver were examined by immunohistochemistical method. Also hydroxyproline (Hyd) and malondialdehyde (MDA) in the liver, alanine aminotransferase (AlaAT), aspartate aminotransferase (AspAT), and albumin (Alb) levels in the serum were measured. RESULTS: SA-A inhibited serum AlaAT and AspAT activities, decreased MDA and Hyd contents, alleviated liver fibrogenesis, protected deposition of type I and III collagen in liver matrix. The actions of SA-A on liver fibrosis were similar to those of Col and SMB, action of SA-A decreasing MDA was better than that of Col. CONCLUSION: SA-A has marked effects against liver injury and fibrosis, associated with its anti-lipid peroxidation actions.
