Studies on anti-early hepatic fibrosis of no donating-oleanlic acid derivatives in rats / 中国临床药理学与治疗学

ABSTRACT

AIM: To investigate protect effect of the NO donating-oleanlic acid derivatives on hepatic fibrosis in rats. METHODS: The rat model with early hepatic fibrosis was induced by carbon tetrachloride (CCl_4). ZCⅡ_2 at the dose of 128 and 64 mg?kg -1 had been given orally for 30 days. Serum level of the total protein (TP), albumin (ALB), the albumin/globulin (A/G) and ALT, AST. The hyaluronic acid (HA), laminin (LN), the procollagen type Ⅲ (PCⅢ) and the level of MDA, GSH-Px in liver tissues were determined. Pathological examination to reveal the extent of liver damages was observed. [WTHZ]RESULTS: ZCⅡ_2 at the dose of 128 mg?kg -1 increased the serum TP, ALB, and A/G and decreased HA, LN, PCⅢ, ALT, and AST more significantly than the model group, and hepatic pathological injury was abated to some degree. CONCLUSIONS: ZCⅡ_2 at the dose of 128 mg?kg -1 can attenuate liver damages, protect against lipoperoxidation and attenuate hepatic fibrosis induced by CCl_4.
