we studied the possible interplay between plasma bradykinin ( p-bk ) and the renin-angiotensin axis in essential hypertension , the effect of catecholamine on p-bk by standing and norepinephrine ( ne ) infusion , and the possible role of bradykinin in the hypotensive mechanism of angiotensin i converting enzyme inhibitor ( captopril ) in renin-independent essential hypertension .
