Our study pertains to evaluate the protective effect of selenium (Se), used as a nutritional supplement, against aluminium chloride induced cardiotoxicity in rats. Rats have received during 21 days either AlCl3 (400 ppm) via drinking water, AlCl3 associated with Na2SeO3 (0.5 mg/kg of diet) or only Na2SeO3. Co-administration of Se to AlCl3 treated rats alleviated heart oxidative stress objectified by a decrease of malondialdehyde, hydrogen peroxide and protein carbonyls levels. An improvement in antioxidant redox status, enzymatic (catalase, superoxide dismutase and glutathione peroxidase) and non enzymatic (reduced glutathione, non protein thiols and vitamin C) was also observed in Se treated rats.  LDH and CK activities, TC, LDL-C levels, TC/HDL-C and LDL-C/HDL-C ratios were increased, while HDL-C and TG decreased in rats treated with AlCl3. Cardiac biomarkers and lipid profile were restored to near control values by the supplementation of Se. Our results revealed that Se, a trace element with antioxidant properties, was effective in preventing heart damage induced by aluminium chloride.
