The kidney may cause hypertension by the elaboration of a pressor material in the presence of renal ischemia. The prevailing theory is that a decrease in the pressure within the renal afferent arteriole (1, 2) causes the juxtaglomerular apparatus to release the enzyme renin (3), which in turn acts enzymatically upon a substrate in the circulation to produce the decapeptide angiotensin I. Angiotensin I is then acted upon by a converting enzyme to produce the potent pressor octapeptide, angiotensin II (4).
We have attempted to assess the role of the renal pressor mechanism in various hypertensive states. Two different methods
