[Antioxidant activity and functional endothelium characteristics before and after the operation in patients with atherosclerosis obliterans].

Data of 410 male patients operated on account of atherosclerosis obliterans of lower limbs vessels. Biochemichal parameters of functional endothelium status of the arteriae after operative treatment are studied. Superoxide dismutase activity and nitric oxide level are registered before and 5 days after the operation. Statistically reliable changes of the biochemical parameters in dependence of methods of the operative treatment are determined.
