Activity of cholinesterase was higher in young erythrocytes when the cell populations of various age were studied; the enzymatic activity was increased after addition of valinomycine into a medium independently on the antibiotic concentration and the enzyme activation was more pronounced in the old population of erythrocytes. The same alterations were observed in presence of calcium ionophore A 23187 and nystatin. Alterations in the enzymatic activity appear to depend on changes of erythrocyte membrane properties in ageing as well as on introduction of ionophore into the membrane.
