Chemical liver and kidney injury have become a serious concern to human. Side effects occur when they are treated with medicine. The present study evaluated the preventive effect of Cyclocarya paliurus polysaccharides (CP) on hepatic and renal injury in carbon tetrachloride (CCl4) induced mice. The results showed that CP treatment could effectively prevent H2O2-induced oxidative damage of NCTC-1469 cells. Administrated with CP could ameliorate the body weight loss and organ swelling of mice induced by the 0.2% CCl4. Compared with the model group, CP groups have beneficial effects in decreasing ALT, AST, TBA and CRE levels in serum. In addition, the expression of CYP2E1 in the liver was also significantly decline after continuous administration of CP. Moreover, pre-administration of CP can improve the antioxidant status of liver and kidney (MDA and SOD, GSH-Px). Histopathological studies also supported the improvement of CP on liver and kidney of CCl4-induced mice. These results indicate that CP may be of therapeutic value in ameliorating the hepatic and renal oxidative stress caused by CCl4, through its antioxidant properties.
