[Ca-binding capacity and the membrane structure of the erythrocytes in certain types of experimental hypertension in rats].

The authors studied the microstructure of erythrocyte membrane (using polarization method of fluorescent probes) and its Ca-binding property in rats with spontaneous, renal and DOCA-salt hypertension. Rats with spontaneous hypertension showed increased microviscosity of erythrocyte membrane and decrease in its property of binding Ca ions, which is not recorded in renal and DOCA-salt hypertension. Salt overload exerted no influence on both parameters studied.
