in this study, we investigated the cardioprotective effects of resveratrol. rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...
Antioxidant enzymes protect cells against oxidative stress and are associated with stress tolerance and longevity. In animals, variation in their activities has been shown to relate to species ecology, but in plants, comparative studies with wild species are rare. We investigated activities of five antioxidant enzymes - ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), per...
Background and Objectives:Oxidative stress has been reported to provide neurodegeneration in multiple sclerosis (MS). Coenzyme Q10 is an endogenous lipid-soluble antioxidant. Up-to-date, no intervention studies have investigated coenzyme Q10 supplementation in MS. The purpose of this study was to investigate oxidative stress and antioxidant enzyme and lipid peroxide activities in women with MS...
Background: Blindness due to cataract is a major and important problem in Pakistan. The problem is expected to increase in future due to increase in tobacco smoking. The aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in Karachi, Pakistan. Methods: 20 cataract patients were randomly selected from Out Patient De...
As a safeguard against oxidative stress, the balance between the main antioxidant enzymes including superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) was believed to be more important than any single one, for example, dual-functional SOD/CAT enzyme has been proved to have better antioxidant ability than either single enzyme. By combining traditional fusion protein tec...
