Abstract

The evaluation of the features of the erythrocyte response to the action of ozone in
experiments in vitro was carried out. An increase in the effect of this gas on the parameters of oxygen
transport in a suspension of erythrocytes was revealed, which is more pronounced with the addition of a
donor of gas-transmitter nitrogen monoxide (nitroglycerin) and is not observed with the introduction of
hydrogen sulfide.Incubation of erythrocyte suspension with ozone causes the development of oxidative
stress, which is manifested by an increase in the concentrations of diene conjugates, malondialdehyde, and a
decrease in catalase activity, which indicates an overload of antioxidant defense mechanisms. Nitroglycerin
and sodium hydrosulfide do not change the activating effect of ozone on the processes of free radical
oxidation, however, they activate the enzymatic link of the antioxidant defense catalase.
