AIM OF THE STUDY: To investigate the protective effects of dehydrocavidine (DC), a main active ingredient of Corydalis saxicola Bunting (Yanhuanglian), on carbon tetrachloride (CCl4)-induced hepatotoxicity and the possible mechanisms involved in male Sprague-Dawley rats. MATERIALS AND METHODS: Acute hepatotoxicity was induced by CCl4 intoxication in rats. Serum biological analysis, lipid peroxides and antioxidants estimation, histopathological studies were carried out. RESULTS: Both pre-treatment with DC prior to CCl4 administration and post-treatment with DC after CCl4 administration significantly prevented increases in serum enzymatic activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and total bilirubin (TBIL). In addition, pre- and post-treatment with DC also significantly prevented formation of hepatic malondialdehyde (MDA), depletion of glutathione peroxidase (GPx) and depression of superoxide dismutase (SOD) in the liver of CCl4-intoxicated rats. ALT, AST, LDH, ALP and TBILL levels, as well as MDA, SOD and GPx activities were unaffected in normal rats by treatment with DC alone. GST, a phase II enzyme, had no significant changes during our experiments. Histopathological changes induced by CCl4 were also significantly attenuated by DC treatment in both preventive and curative experiments. CONCLUSIONS: DC has a potent hepatoprotective effect on CCl4-induced liver injury in rats through its antioxidant activity.
