Regulation of hemodynamic parameters under conditions of systemic administration of angiotensin II and angiotensin IV to rats after carotid glomectomy

Abstract

Systemic administration of angiotensin II was followed by an increase in systolic BP and HR in rats with carotid glomectomy, the time of attaining maximum values in treated animals was much higher than in sham-operated controls. Injection of angiotensin IV slightly reduced systolic BP in sham-operated animals and increased it in rats with carotid glomectomy. The involvement of the local renin-angiotensin system of the carotid body in systemic mechanisms of hemodynamics regulation is discussed.
