Effect of vertebral artery infusions of oxytocin on plasma vasopressin concentration, plasma renin activity, blood pressure and heart rate and their responses to hemorrhage.

Abstract

Infusion of oxytocin into one vertebral artery of anesthetized dogs did not alter plasma vasopressin concentration, blood pressure or heart rate. However, there was a significant (p less than 0.01) increase in plasma renin activity (PRA; delta = 7.6 +/- 2.3 ng/ml X h). A 35% hemorrhage caused blood pressure to fall by 9.4 +/- 4.0 mm Hg (p less than 0.01… (More)
