the effect of an acute saline load on the sodium pump was determined from measurements of intracellular sodium and potassium , ouabain-inhibitable sodium efflux , and the number of sodium-potassium adenosine triphosphatase ( na , k-atpase ) sites per cell ( using 3h-ouabain binding ) of erythrocytes from 22 hypertensive and 21 normotensive subjects before and after a 2-1 infusion of 0.9 % saline over a 4-hour period .
