ABSTRACT
This study focused on the relationship between NO concentration and different parameters of the free radical scavenging system. The study was performed on 40 children with congenital heart disease [20 cyanotic and 20 acyanotic] as well as 15 healthy children serving as a control group, aiming to evaluate the effect of a long period of hypoxia on NO level, enzymatic antioxidants [copper-zinc superoxide dismutase] and glutathione peroxidase [GPX], nonenzymatic antioxidants [vitamins C and E] and plasma level of malondialdehyde [MDA] as a marker of lipid peroxidation plus reduced glutathione [GSH]. The results showed that there was a significant reduction in the NO concentration in parallel with a reduction in the plasma antioxidant vitamins, blood enzymes and GSH in children with cyanotic heart defects, meanwhile the level of MDA was significantly increased
