title: [Effect of the enzymatic treatment of erythrocyte membranes on their interaction with neutrophilic leukocytes].
abstract: The treatment of erythrocytes with different enzymes (neuraminidase, trypsin and papain) has been studied for its effect on the lipid peroxidation in their membranes, activity of antioxidant enzymes and on the ability of such erythrocytes to interact with neutrophilic leucocytes. It is shown that desialization of the membrane erythrocyte structures causes the intensification of lipid peroxidation in the membranes, decrease of their stability. Simultaneously, the interaction of neutrophils increases. The treatment with proteases causes the opposite changes. It is shown possible to split out the end molecules of sialic acids with exposure of the subterminal residues of B-galactose as a result of the effect of active oxygen forms. An assumption is advanced concerning the functional conjugation of the free-radical oxidation and proteolysis in provision of stability of the cell membranes.
