Abstract
- Abstract: The aim of the study was to investigate the potentially protective effects of fraxetin on carbon tetrachloride (CCl4) induced oxidative stress and hepatic fibrosis in Sprague–Dawley rats. In this study, rats were divided into five groups, including normal controls, model, silymarin as the positive control, fraxetin 20mg/kg and fraxetin 50mg/kg. After 8weeks, activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBIL) were checked. The levels of protein carbonyls, thiobarbituric acid-reactive substances (TBARS) and antioxidant enzymes such as catalase, SOD and glutathione peroxidase (GSH-Px) were determined after fraxetin administration. The hydroxyproline levels and histopathologic examinations of hepatocyte fibrosis were also determined. We found that fraxetin at doses of 20 and 50mg/kg for 8weeks significantly reduced the levels of TBARS and protein carbonyls compared with CCl4 group. Fraxetin significantly increased the activities of catalase, SOD and GSH-Px in the liver. We also found that fraxetin prevented CCl4 induced hepatic fibrosis by histological observations. These results indicate that fraxetin exhibits potent protective effects against CCl4 induced oxidative stress and hepatic fibrosis. [Copyright &y& Elsevier]
