Abstract:

The present study compared the activities of antioxidant enzyme SOD, CAT, GPx and the content of malondialdehyde (MDA) in Liver and kidney of toad Bufo raddei sampled from two different polluted sites of the Upper Yellow River. It was found that the toad from Lanzhou (polluted) had significantly descent of CAT and GPx activities in liver compared with those of Liujiaxia (relatively unpolluted), while the activity of SOD of the male and MDA content of the female from Lanzhou were both higher in liver than those of from Liujiaxia. There was no significant difference of the nephritic antioxidant enzyme activity except GPx depression in the female toad from Lanzhou as well as the increased MDA content in kidney. It was suggested that the environmental pollution in the Upper Yellow River induced oxidative stress and increase of lipid per oxidation on Bufo raddei.
