ABSTRACT
Objective: To explore the antifibrotic effect of echinacoside on carbon tetrachloride (CCl4)-induced hepatic fibrosis in rats. Methods: Male Wistar rats were randomly divided into normal control (n = 8), model (n = 14), and echinacoside treatment (n = 14) groups. The hepatic fibrosis model was induced by CCl4 compositor. The rats were ig administered with echinacoside at a daily dose of 50 mg/kg. The anti-oxidant status, liver function parameters, and hepatic hydroxyproline content were detected by chromatometry. The serum levels of hyaluronic acid (HA), type IV collagen (CIV), type III precollagen (PIIIP), and laminin (LN) were assayed with radioimmunoassay. The hpatic injury was detected by haematoxylin-eosine staining. The deposition of collagen was observed with Masson staining. Results: Echinacoside increased the superoxide dismutase activity and reduced the levels of malondialdehyde, aspartate aminotransferase, alanine aminotransferase, HA, CIV, PIIIP, and LN in serum. Echinacoside could also reduce the hydroxyproline content in liver, alleviate hepatic injury, and inhibit collagen deposition. Conclusion: Echinacoside possesses antihepatic fibrosis effect. © 2013 Tianjin Press of Chinese Herbal Medicines.
ABSTRACT
Objective: To observe the effect of Haobie Yangyin Ruanjian Decoction (HYRD) on rats with hepatic fibrosis induced by CCl4 composited factor. Methods: Wistar rats were randomly divided into seven groups: control group, model group, HYRD groups of low, medium, and high doses, positive groups of Fufang Biejia Rungan Tablets, and colchicin. Model of hepatic fibrosis was induced by CCl4 composited factor. Malondialdehyde (MDA), total protein (TP), albumin (ALB) in serum and hydroxyproline (Hyp) in liver were detected by chromatometry; MMP-2 and MMP-9 activities in liver were detected by gelatin zymography; α-SMA expression in liver was evaluated by immunohistochemical method. Results: MDA in serum and Hyp in liver were decreased gradually in HYRD groups compared with those of model group; TP and ALB in serum were increased gradually in HYRD groups compared with those of model group; MMP-2 activity in liver was decreased in HYRD groups compared with those of model group; MMP9 activity had no significant change in each group and α-SMA expression was decreased gradually in HYRD groups compared with those of model group. Conclusion: HYRD can antagonize the hepatic fibrosis induced by CCl4 composited factor.
