The dynamics of oxidative metabolism in healthy people's blood (n = 30) under the influence of gaseous nitric oxide and dinitrosyl iron complexes is explored. In all blood samples we studied lipid peroxidation intensity and malonic dialdehyde in plasma and erythrocytes, plasma antioxidant potential and activity of superoxide dismutase. During our investigations it was possible for the first time to identify the peculiarities in the responses of pro- and antioxidant blood systems in vitro to the treatment with nitrogen monoxide as the free. radical and its storage form (as a component of dinitrosyl iron complexes). So, a pronounced prooxidant effect for the gas flow from the "Plazon" apparatus moderately decreases when a tenfold dilution of a NO-containing mixture is made. Gas flow from the experimental NO-generator causes minimal prooxidant action, and injection of water solution of dinitrosyl iron complexes in blood specimens leads to an antioxidant action, as limitation of lipoperoxidation processes in plasma and stimulation of superoxide dismutase in erythrocytes. |
