title: Altered activity of the sodium-potassium pump in arteries of rats with steroid hypertension.
abstract: 1. Ouabain-sensitive uptake of 86Rb, a measure of the Na+-K+ pump activity, was studied in tail arteries of rats made hypertensive with deoxycorticosterone and saline. 2. Decreased activity of the ouabain-sensitive Na+-K+ pump supports the hypothesis that the activity of Na+-K+ pump is suppressed in volume expanded hypertension.
