title: [Free radical processes involving oxygen in biosystems under ultraviolet radiation].
abstract: Literary data concerning the influence of ultra-violet radiation on redox processes with participation of oxygen in biosystems are analyzed and generalized. The possible mechanisms of oxygen radicals' generation and antioxidant protection in humans under extreme conditions are considered. The methods of research of antioxidant activity of biologically active compounds are characterized. Using electrochemical method developed by the authors, the results of investigations of antioxidant and anti-radical activities of a wide number of medications are presented.
