A brief account for the renal renin‐angiotensin system (RAS), its inhibitors and receptors, as for the presence of an intrinsic cerebral RAS is initially provided. The review is then focused upon the circumventricular organs as cerebral targets for blood‐borne angiotensin II (Ang II) and on centrally mediated Ang II effects.

Human Leukocytes Contain Angiotensin I, Angiotensin II and Angiotensin Metabolites
International Archives of Allergy and Immunology, 2009Angiotensin I (ANG I) and angiotensin II (ANG II) were measured radioimmunologically in human leukocytes extracted with a mixture of acetone, 1N HCl and water (40:1:10 vol). The analytical recoveries of 125I-ANG I and 125I-ANGII, which were added prior to extraction, were 92.00 ± 3.I0 and 99.19 ± 0.91% (mean ± SEM; n = 12).

SUMMARY1. One of the most important issues in the field of hypertension research centres on the therapeutic use of inhibitors of the renin‐angiotensin system (RAS). Inhibitors of the RAS have potent anti‐hypertensive effects, even in experimental models of hypertension and in human essential hypertension, where the activity of the peripheral RAS is low

Conversion of angiotensin I to angiotensin II
The American Journal of Medicine, 1976The angiotensin I converting enzyme has two important functions: it inactivates bradykinin and converts angiotensin I to angiotensin II. Inhibition of the enzyme blocks the renin-angiotensin system and decreases systemic blood pressure if the pressure is maintained or increased by renin. The enzyme occurs in a variety of tissues and cell forms.

Regulatory Peptides, 1999
The object of this review is to describe the role of the renin-angiotensin system in control of aldosterone secretion. The review focuses on the roles of the circulating renin-angiotensin (RAS) system, the activity of which is determined predominantly by control of renin secretion from the kidney and on the role of the intra-adrenal RAS.

Pharmacoangiography with Angiotensin
Radiology, 1974Angiotensin was investigated as a pharmacoangiographic agent in 80 patients, employing selective catheterization of various arteries. The diagnostic value of angiography was improved in about 70% of cases. This improvement usually consisted of enhanced filling of smaller arteries with a higher concentration of contrast material.

Radioimmunoassay of Angiotensin
Nature, 1968HABER et al.1 showed that antibodies elicited in rabbits by copolymers of angiotensin with poly-L-lysine can be used for radioimmunoassay of angiotensin. The following are details and some results of the method we have developed. Comparing the binding affinity of three different rabbit antisera to Val5-angiotensin II amide (‘Hypertensin’, Ciba) and ...

iAngiotensin's renal and circulatory actions hare long been known. Some of these actions are mediated by the central nerrous system. More recently angiotensin ha~" been shown to be .~ powerful stimulus to thirst. It now appears that angiotensin is act.~ally localized in neur,nes in certait; regions of the central nerrous system.

Angiotensin-(1–7) and the renin–angiotensin system
Current Opinion in Nephrology and Hypertension, 2007In this review we will focus on the recent findings related to angiotensin-(1-7) as an angiotensin II counter-regulatory peptide within the renin-angiotensin system.The identification of the angiotensin-converting enzyme homologue ACE2 as an angiotensin peptide processing enzyme and of Mas as a receptor for angiotensin-(1-7) has contributed to ...

CONVERSION OF ANGIOTENSIN I TO ANGIOTENSIN II IN SHEEP
Clinical and Experimental Pharmacology and Physiology, 1978SUMMARY1. The methodology for measurement of angiotensin I in whole blood is described.2. Angiotensin I was measured in arterial and venous blood samples from sodium‐loaded, sodium‐replete and sodium‐depleted sheep. Venous blood concentrations were higher than arterial angiotensin I concentrations.
