[Erythrocyte membrane permeability of sodium in different types of chronic experimental hypertension].

The permeability of the red blood cell membrane for sodium in rats with spontaneous genetic hypertension, in rats with renovascular and DOCA-salt-induced hypertension as well as the effect of high salt diet on the permeability were studied using the flame photometry method. The increase permeability of the red blood cells in the rats with spontaneous genetic hypertension was observed, while no changes occurred in the cases of DOCA-induced and renovascular hypertension. Salt load as well as deoxycorticosterone administration had no effect on the permeability of the red blood cell membrane.
