Oxidative stress and hepatotoxicity of Rana chensinensis exposed to low doses of octylphenol.

This study investigated the effects of low doses of octylphenol (OP) on the oxidative stress and hepatotoxicity in amphibian liver. The frog, Rana chensinensis, were exposed to 10, 10, 10 mol/L OP for 10, 20 and 30 days. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) in liver were reduced at first, then recovered slightly, and the content of malondialdehyde (MDA) and hydrogen peroxide (HO) were increased significantly.
