Angiotensin and angiotensin receptors in cartilaginous fishes

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2001
In mammals, a principal bioactive component of the renin-angiotensin system (RAS), angiotensin II (ANG II), is known to be vasopressor, dipsogenic, a stimulant of adrenocortical secretion and to control glomerular and renal tubular function. Historically, a RAS analogous to that found in mammals was thought to have first evolved in the bony fishes ...

Is the adrenal angiotensin receptor angiotensin II — or angiotensin III like?

Acta Endocrinologica, 1983
Abstract. In order to determine whether the adrenal receptor is primarily directed at angiotensin II (All) or angiotensin III (AIII) the following in vitro experiments were performed examining aldosterone responsiveness in isolated glomerulosa cells.

Conversion of Angiotensin I to Angiotensin II

Nature, 1967
Results obtained with the blood bathed organ technique indicate that angiotensin I is converted rapidly to angiotensin II in the pulmonary circulation and not by an enzyme in the blood.

Human Leukocytes Contain Angiotensin I, Angiotensin II and Angiotensin Metabolites

International Archives of Allergy and Immunology, 1994
Angiotensin 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-ANG II, which were added prior to extraction, were 92.00 +/- 3.10 and 99.19 +/- 0.91% (mean +/- SEM; n = 12).

Angiotensin in atherosclerosis

Current Opinion in Nephrology and Hypertension, 2004
While it is well established that angiotensin II promotes cardiovascular and renal disorders, recent evidence has indicated a pivotal role in atherosclerotic disease which is distinguished by the central abnormality of lipid accumulation within the vascular wall.Studies published in the last year show that angiotensin II activity is increased in ...

Angiotensin and the brain

Acta Physiologica Scandinavica, 1995
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.

Angiotensin and thirst

Trends in Neurosciences, 1978
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.

Pharmacoangiography with Angiotensin

Radiology, 1974
Angiotensin 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.
