Abstract

Bradykinin (BK) causes vasodilation and increases free water and sodium excretion in the kidney and stimulates smooth muscle contraction in the ureter and bladder. Several proposed sites of action for BK include the renal medullary collecting duct, renal blood vessels and the ureter and bladder smooth muscle. This study employs 3H-BK autoradiography to localize the sites of BK action. 3H-BK binding sites in the kidney are localized in the medullary interstitium where BK may produce prostaglandins which mediate its blood flow, natriuretic and diuretic effects. 3H-BK binding sites in the ureter and bladder are localized in the lamina propria below the basal epithelial layer and absent over the muscle layers suggesting an indirect action on urinary tract smooth muscle.
