Abstract
The aim of this study was to investigate the effects of cadmium-induced peroxidative damage to rat adrenals. Cadmium significantly increased adrenal lipid peroxidation in a dose- and time-related manner. Cadmium-induced lipid peroxidation was accompanied by a marked elevation in adrenal iron (Fe) levels, in particular the free elemental form. Chelation of Fe with deferoxamine decreased the cadmium effect on lipid peroxidation. Selenium (Se) was also effective in inhibiting Cd-induced adrenal lipid peroxidation. Data indicate that Cd-induced lipid peroxidation in rat adrenals may be dependent upon Fe and Se levels in this tissue.
