Furosemide and bumetanide-sensitive Na+ fluxes in erythrocytes from genetically hypertensive rats (SHR).
Na+ and K+ fluxes from erythrocytes of SHR and WKY control rats have been studied. Fluxes were measured in both fresh and sodium-loaded (after exposure to ouabain or PCMBS) erythrocytes. Pump activity appears higher and furosemide or bumetanide sensitive Na+ efflux lower in SHR compared to WKY suggesting a similar abnormality in SHR genetic hypertension as in human hypertension.
