Active oxygen species have been proposed to be involved in the aging process of the brain, therefore alterations in the activities of enzymes involved in the defense system against free radicals and other active species could substantially influence the aging process. This study is planned to determine the brain superoxide dismutase (SOD) and catalase activities which defend the components of brain cells against active oxygen species, in order to evaluate whether they play a role in the aging process. The activities of SOD and catalase were measured in the cerebral cortex and cerebellum of Swiss male albino rats aged either …

Vitamin E and other antioxidants prevent or minimize oxidative damage in biological systems. The level of antioxidant defense sufficient to protect the organism from high free radical concentrations is one of the new horizons for Vitamin E research. The role of Vitamin E as a protective agent aganist oxidative stress was evaluated by meas-uring the antioxidant enzyme catalase (CAT) activities in different tissues of Swiss male albino rats aged two months. In this study, rats were divided to three groups; control (n=10), E 1 (n=5) which received 25 mg/kg. per day of Vitamin E, IM. for 10 days and E …

It has been maintained that free oxygen radicals (FOR) that occur in cell have important roles in the ethiopathogenesis of diabet, and that cell damage progressing as a result of their accumulation is responsible for the development of diabetic complications. In recent years, along with free oxygen radicals, antioxidant mechanisms and the substances influencing as free radical cleaner have been investigated in connection with diabet. With this respect, in a total of 30 patients with type II Diabetes Mellitus (NIDDM), 15 with diabetic retinopathy and 15 without diabetic retinopathy, and in 20 healthy subjects, we measured glutathione (GSH), catalase and …
