Protective role of vitamin E on nickel and/or chromium induced oxidative stress in the mouse ovary.

In the present study, we report the invivo effects of nickel chloride (NiCl2; 8 and 16 mg/kg body weight) and/or potassium dichromate (K2Cr2O7; 5 and 10mg/kg body weight) in the ovary of adult mice. The protective role of vitamin E (2mg/kg body weight) along with their combination was also studied. Nickel and/or chromium to mice enhanced the levels of lipid peroxides in the ovary, which was accompanied by a significant decline in the levels of protein, glutathione, total ascorbic acid and activities of superoxide dismutase and catalase.
