title: [The state of antioxidant defense system in patients with multiple gastroduodenal peptic ulcers].
abstract: There were examined 32 patients with multiple gastroduodenal ulcers ageing 24-65 yrs (basic group) and 30 patients with gastroduodenal ulcers of conventional size (group of compare). The antioxidant defense system (ADS) state was studied, using analysis of its enzymes (catalase and superoxydismutase) activity, integrating index F was calculated as well. Prominent disorders of the ADS (the catalase activity increase and the superoxydismutase activity decrease) were revealed in patients with multiple gastroduodenal ulcers. Also the reduction of index F, which characterizes the ratio of prooxidant and antioxidant properties of the blood, was noted.
