Oxidative stress mediated by pro-oxidants has been implicated in the pathogenesis of vascular disorders. However, the effect of pro-oxidants on myogenic regulation of vascular function and the differential influence of gender is not known. Superoxide dismutase (SOD), an intracellular enzyme restricts excess pro-oxidant levels and may limit vascular dysfunction. We therefore tested the effects o...
Reactive oxygen species (ROS) have been implicated in the pathogenesis of many clinical disorders such as adult respiratory distress syndrome, ischemia-reperfusion injury, atherosclerosis, neurodegenerative diseases, and cancer. Genetically engineered animal models have been used as a tool for understanding the function of various antioxidant enzymes in cellular defense mechanisms against vario...
To examine effects of exogenous Cd on the kidney antioxidant defense system (AOS) and the possible protective role of Se against Cd toxicity, male Wistar albino rats (2 months old) were exposed during 30 days to oral intake of 200 ppm Cd (as CdCl2), 0.l ppm Se (as Na-selenite) or to the same doses of Cd / Se, simultaneously. Marked accumulation of Cd (23.44 +/- 0.69 micrograms/g w.m.) and marke...
Conclusions Compared with the general population, the prevalence of cataract in Down’s syndrome was raised in those aged 45 to 64, but not in those aged 65 to 75 years; the latter might be a function of the relatively small number of patients in this age group. The increased prevalence of cataract found in those in the 45to 64-year-old age group may be the result of increased levels of CuZnSOD,...
