title: Sex-related differences in cadmium-induced lipid peroxidation in the rat.
abstract: Male and female rats were dosed once a day for 2 days injection with 1.5 mg of Cd/kg as CdCl2. 24 hr after administration of cadmium, lipid peroxidation determined by estimation of malondialdehyde (MDA) was greatly increased in male rat liver, but was not in female rats. Cadmium in a larger dose of 4.5 mg/kg, subcutaneous single injection, significantly increased content of MDA in female rat liver. These results suggest that sex-related differences exist in the ability of cadmium to induce MDA formation in rat liver, although administration of cadmium causes the enhancement of MDA formation in both male and female rats. The reason why sex-related differences exist in lipid peroxidation of rat liver is discussed.
