Erythrocyte sodium ion transport system in DOC-salt, Goldblatt, and spontaneously hypertensive rats
1992
Altered erythrocyte Na+ transport has been observed in relation to the pathogenesis of essential hypertension. In the present study, intracellular Na+ and K+ levels, Na+-K+ pump activity, Na+-K+ cotransport, and Na+ passive permeability were measured in erythrocytes of DOC-salt hypertensive (DSH) rats, two-kidney, one clip Goldblatt hypertensive (2KH) rats, and spontaneously hypertensive rats (SHR). The results were as follows:1. In comparison with the control groups, no change in the erythrocyte Na+ level was noted in the DSH and 2KH groups, whereas a significant increase was seen in the SHR group.2. Although no change was noted in the erythrocyte K+ level in the 2KH and SHR groups when compared with the control groups, a significant decrease was seen in the DSH group.3. Na+-K+ pump activity of erythrocytes was not changed in the DSH and 2KH groups when compared with the control group, but a significant increase was noted in the SHR group.4. Na+-K+ cotransport of erythrocytes was not changed in any hyper...
