The effect of chondroitin sulfate against CCl4-induced hepatotoxicity.
This study was conducted to develop a new biomaterial to be used for an antioxidative drug. In this study, the hepatoprotective effect of chondroitin sulfate (CS) (100 mg/kg and 200 mg/kg body weight) was investigated at the antioxidative enzyme levels of liver total homogenate and mitochondria fraction. And the carbone tetrachloride (CCl(4))-induced rats were used as hepatotoxic models. The CCl(4) induced rat has been widely used as a hepatotoxic model due to its practicality, convenience and cost effectiveness since the generation of free oxygen radicals by CCl(4) injection was proposed as an important causative agent of hepatotoxicity. Malondialdehyde (MDA) levels were determined as well as the activities of superoxide dismutase (SOD), catalase (CAT), reduced-glutathione (GSH), oxidized-glutathione (GSSG) and glutathione peroxidase (GPx) in the liver. In addition, histopathology of liver tissue was investigated. Liver antioxidative enzyme activity was elevated while MDA concentration was decreased in all CS treated animals. The results demonstrated that CS protected oxidative stress in a dose dependent manner. Moreover, inflammation and cirrhosis in liver tissue of CS treated group were significantly decreased. It gave us an impression that CS might be a radical scavenger.
