Abstract

1 Prolonged infusion (11 h) of both saralasin and angiotensin-converting enzyme inhibitor (SQ20881) gradually lowered BP in two-kidney hypertensive rats to levels similar to that in normotensive rats infused with dextrose.

2 Saralasin did not lower BP in DOCA-salt-hypertensive rats.

3 These observations support the notion that in chronic renal hypertension, angiotensin II may maintain hypertension by a slowly developing action.

4 Plasma angiotensin II in rats infused with SQ20881 was suppressed relative to renin, but was not eliminated.

5 Chromatography of angiotensin II extracts from dogs infused with converting enzyme inhibitor (SQ14,225) showed that the very high levels of angiotensin I achieved after treatment with SQ14,225 can lead to falsely high estimated angiotensin II levels as a result of angiotensin I cross-reacting with the angiotensin II assay.
