Effect of Chronic Angiotensin-Converting Enzyme Blockade on Pressor Responses to Exogenous Angiotensin II, Noradrenaline and Vasopressin in Deoxycorticosterone Acetate Salt (DOCA)-Induced Hypertensive Rats

[摘要] References(26)Effect of chronic angiotensin converting enzyme blockade on the pressor response to exogenous angiotensin II, noradrenaline and vasopressin were evaluated in DOCA-salt induced hypertensive rats using teprotide. The blood pressure of rats receiving teprotide chronically was reduced markedly. The pressor responses to exogenous angiotensin II was accentuated, while that of noradrenaline and vasopressin were significantly reduced. It is concluded that besides the angiotensin converting enzyme blocking action, the decrease in sensitivity of the pressor response to noradrenaline and vasopressin may contribute towards the antihypertensive activity of teprotide given chronically.
