Plasma aldosterone fell while both blood angiotensin I and renin concentration rose. 2...

... but not the high sodium diet. 4. These results suggest that the renin-angiotensin-aldosterone system is a normal mechanism for maintaining blood pressure and aldosterone secretion in normotensive man. The system may also be involved in the maintenance of sodium balance. 5. These results may lead to a better...

By immunoperoxidase technique, immunoreactive angiotensin II (ANG II) was located in the cell bodies of many magnocellular neurons in the supraoptic and paraventricular nuclei of the hypothalamus and their pathways to median eminence and posterior...

...S. C. Textor; H. R. Brunner; H. Gavras 1. To investigate the non-angiotensin effects of converting enzyme inhibition, angiotensin II was infused intravenously at 30 ng/min for 9 days in conscious rats to produce moderate blood pressure elevation. One group was given captopril (SQ 14 225) by gavage...
