unusual facts about Renin-angiotensin-aldosterone system



Angiotensin

Angiotensin was independently isolated in Indianapolis and Argentina in the late 1930s (as 'angiotonin' and 'hypertensin', respectively) and subsequently characterised and synthesized by groups at the Cleveland Clinic and Ciba laboratories in Basel, Switzerland.

ARBS

ARBs – Angiotensin II receptor blockers; a group of pharmaceuticals

David Cushman

He credits Dr. John Vane with suggesting angiotensin converting enzyme as a target for research at The Squibb Institute.

Effective arterial blood volume

The kidney mechanisms used to restore EABV include, (1) sympathetic nerve activity; (2) Atriopeptin (ANP) secretion from the atria; (3) Starling forces; (4) Renin-angiotensin-aldosterone system.

Epimer

Epimerisation can be spontaneous (generally a slow process), or catalyzed by enzymes, e.g. the epimerization between the sugars N-acetylglucosamine and N-acetylmannosamine, which is catalyzed by Renin-Binding Protein.

Nesiritide

Nesiritide works to facilitate cardiovascular fluid homeostasis through counterregulation of the renin-angiotensin-aldoesterone system, stimulating cyclic guanosine monophosphate, leading to smooth muscle cell relaxation.

Pulse pressure

If the patient suffers from elevated pulse pressure, treatment may include medications that address this factor, such as an angiotensin-converting enzyme inhibitor (ACE inhibitor).

Robert Tigerstedt

Tigerstedt's work on renin was probably inspired by Brown-Sequard's work examining the effect of organ extracts on physiological function.

Telmisartan

Telmisartan is an angiotensin II receptor blocker that shows high affinity for the angiotensin II receptor type 1 (AT1), with a binding affinity 3000 times greater for AT1 than Vasomotor

Endothelin, and angiotensin are the vasocontrictors of smooth muscles while nitric oxide and prostacyclin are vasodilators of the smooth muscles.
