[Anti-edematous action of EDTA, its effect on lipid peroxidation intensity and various components of the antioxidant system of the lungs in rats exposed to NO2]. / Protivootechnoe deistvie EDTA i ee vliianie na intensivnost' perekisnogo okisleniia lipidov i nekotorye komponenty antioksidantnoi sistemy legkikh krys pri vozdeistvii NO2.

It has been studied how preventive administration of EDTA influences toxic NO2- induced pulmonary edema and disturbances in antioxidant systems. The compound in question, being preventively administered, has exerted a significant antiedematic effect as a result of a decrease in lipid peroxidation intensity and protection of the most important substrate components of the nonenzymatic antioxidant system from the oxidation effect.

[Correction of lipid peroxidation intensity and glutathione system by derivatives of polygalacturonic acid after exposure to nitrogen dioxide]. / Korrektsiia proizvodnymi poligalakturonovoi kisloty intensivnosti perekisnogo okisleniia lipidov i sistemy glutationa pri vozdeistvii dioksida azota.

Influence of intraperitoneal administration of polygalacturonic acid derivatives at a dose of 100 mg/kg on the glutathione system and lipid peroxidation in the rat lung after treatment with NO2 was studied. A considerable decrease of lipid peroxidation intensity by these derivatives was caused not only by ability of these compounds to the chelate formation and absorption of free radicals, but also by the substantial activation of the glutathione system.
