oa Central African Journal of Medicine - Intracellular concentrations and ouabain-induced fluxes of sodium and potassium in erythrocytes of normotensive Zimbabweans

Volume 37, Issue 4
  • ISSN : 0008-9176



Intracellular Na and K concentrations as well as ouabain-induced transmembrane net Na and K fluxes were measured in erythrocytes (TBC) of 22 adult Black male Zimbabweans. The intracellular Na concentration is higher than most values reported from studies of Whites, but the intracellular K concentration and the ouabain-induced Na influx compare with literature values. No significant correlation was found between intracellular Na concentration and blood pressure.
