[Effect of vitamin E on the mechanical fragility and the Mg++-ATPase of rabbit erythrocytes]

Abstract

We have established that Mg++ activated ATPase in red cells of rabbits is not changed by vitamin E injection, even if the mechanical resistance of these red cells is increased. Enzyme activity, however, cannot be correlated with this increased mechanical resistance. Probably, the effect of vitamin E on membrane lipids may be supposed to exist, though its effect on membrane proteins cannot be fully excluded.
