Assesment of antioxidative enzymes activity and intensification of lipids peroxidation in asthmatic patients.

Chronic immunoalergic in flammatory reaction plays a key role in pathogenesis of asthma. Importance of free oxygen radicals in mechanism of chronic inflammatory process has been proved. Activity of two antioxidative enzymes: isoenzymes of superoxide dismutase (SOD), glutathione peroxidase (POX), and concentration of malondialdehyde (MDA) in serum and erythrocytes in asthmatics during exacerbation and improvement of disease were assessed. Disturbances in oxidative system in asthmatic patients have been observed. Lack of significant differences in antioxidative indexes between a period of exacerbation, not complicated by infection and a period of improvement indicates a pathophysiological role of chronic oxygenic stress in asthma. It has been also shown that bacterial infection disturbes efficiency of antioxidative mechanisms. Pneumonol. Alergol. Pol. 2004, 72, 472-47
