[The activity of erythrocyte membrane enzymes in different stressor exposures].

The decrease in activity of acetylcholinesterase and Na,K-ATPase of erythrocyte membranes was found to be the result of stress effects. These decrease may be concerned with the changes of ratio of various erythrocyte population the appearance in blood "old" cells having 1.8-2.0 times lower activity of membrane-bound enzymes. The specific digoxin-like inhibitors of Na,K-ATPase was revealed in blood, which also contribute to the inhibition of the enzyme activity. For correct interpretation of the reason of changes in activity of erythrocyte membrane enzymes in stress conditions the complex of physiological changes on the level of the whole organisms has to be taken into account.
