Renal Intramedullary Infusion of Tempol Normalizes the Blood Pressure Response to Intrarenal Blockade of Heme Oxygenase-1 in Angiotensin II-Dependent Hypertension

摘要

BackgroundPrevious studies have demonstrated that intramedullary inhibition of heme oxygenase-1 (HO-1) increases the blood pressure and superoxide production response to angiotensin II (Ang II) infusion. The current study was designed to test the hypothesis that increased renal medullary superoxide production contributes to the increase in blood pressure in response to blockade of renal medullary HO-1 in Ang II-induced hypertension.
