title: Effect of ethanol on the hemolytic stability of erythrocytes.
abstract: The stability of rabbit erythrocytes to hemolysis induced by different compounds in the presence or absence of ethanol or acetaldehyde has been analyzed. Ethanol slightly reduced erythrocyte stability against acidic hemolysis only after long-term preincubation, but the effect of ethanol on stability to oxidative hemolysis manifested itself immediately after its addition to the cells. Ethanol decreased both stability of cells to oxidative damage and dispersion of the hemolytic curve. Comparison of the effects of ethanol and acetaldehyde showed that the destabilizing effect of ethanol might be caused by either its direct action or the effect of its metabolites formed during preincubation of ethanol with erythrocytes. Possible mechanisms of ethanol and acetaldehyde effects on erythrocyte stability are discussed.
