CARACTERIZACIóN DEL ESTRéS OXIDATIVO EN RATAS WISTAR DIABéTICAS POR ESTREPTOZOTOCINA

diabetes is a chronic metabolic disease. numerous studies have demonstrated that diabetes mellitus is associated to free radicals increase derived from oxygen and to the organism potential antioxidant decrease generating oxidative damage of some cell components like proteins, nucleic acids, carbohydrates and lipids. after 20 days of administration of streptozotocin in wistar rats, we have found a relationship between levels of blood glucose and some markers from antioxidant status. we evaluate oxidative stress markers like catalasa and superoxide dismutase acivities, ferric reducing ability of plasma and thiobarbituric acid reactive species.
