Antioxidant effects of the Uygur herb, Foeniculum Vulgare Mill, in a rat model of hepatic fibrosis / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate therapeutic and antioxidant effects of Uygur Herb Foeniculum Vulgare Mill (FVM) in hepatic fibrosis rats.</p><p><b>METHOD</b>Hepatic fibrosis model was built in rats by subcutaneous injection with 40% CCl4 olive oil mixture. At the same time the rats were given high lipoid-low protein animal feeds for 5 weeks. 94 male SD rats were randomly divided into six groupsblank control group (A-group), 8 rats were feed in normal; prevention model control group (B-group), 10 rats were given saline solution by intragastric administration during make of hepatic fibrosis model; FVM prevention group (C-group), 10 rats were given FVM by intragastric administration during make of hepatic fibrosis model; model control group (D-group), FVM treatment group (E-group); Fuzhenghuayu treatment group (F-group). 22 rats in each D, E, F-group were respectively given saline solution, FVM and Fuzhenghuayu by intragastric administration after hepatic fibrosis model were built. At the 5-th weekend, A, B, C- group rats were sacrificed. At the 6-th, 7-th, 8-th, 9-th weekend, 4-6 rats in D, E, F-group were sacrificed. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) and 8 - hydroxy-2-deoxyguanosine (8-OHdG) were detected, liver tissue homogenate superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) were detected. Histopathologic changes were observed after H.E and Masson staining. The expression of alpha-smooth muscle actin(a-SMA) were detected by immunohistochemical staining. The data were analyzed by SPSS17.0 software.</p><p><b>RESULTS</b>The serum levels of ALT, AST, HA, and LN in the FVM prevention group were significantly reduced compared to the prevention model control group.(P less than 0.05). Rats in FVM treatment group appeared a marked lower serum levels of ALT, AST, HA compared to the model control group (P less than 0.05), and a distinguished lower Inflammation grade and fibrosis stage (P less than 0.05) when the liver section were assayed as well; Rats in FVM treatment group and FVM prevention group had a conspicuous lower content of MDA, 8-OHdG, fibre and a-SMA expression (P less than 0.05), a significantly higher level of SOD, GSH-Px compared to those of in the model control groups.</p><p><b>CONCLUSIONS</b>Foeniculum Vulgare Mill declines liver inflammation response ,and prevent the hepatic fibrosis progression,, this may be due to its effects of antioxidative results.</p>
