TīmeklisThe renin in plasma is allowed to act on the plasma's endogenous substrate, angiotensinogen, producing angiotensin I. This is measured by mass … Tīmeklis2004. gada 1. nov. · Plasma renin is therefore the initiator of the renin-angiotensin-aldosterone system, which has an important role in the homeostasis of water and electrolyte balance and in the regulation of arterial pressure. In most studies, circulating renin has been estimated by assays of plasma renin activity (PRA).

Tīmeklis2014. gada 15. aug. · Reninoma (juxtaglomerular cell tumor) is a rare cause of renin-mediated hypertension. Reninomas are usually diagnosed in adolescents and young adults with occasional reports in younger children. Patients typically present with a long history of headaches leading to a diagnosis of severe hypertension … TīmeklisPlasma renin then carries out the conversion of angiotensinogen, released by the liver, to a decapeptide called angiotensin I. [4] Angiotensin I is subsequently converted to angiotensin II (an octapeptide) by the angiotensin-converting enzyme (ACE) found on the surface of vascular endothelial cells, predominantly those of the lungs.

Tīmeklisrenin. [ re´nin] a proteolytic enzyme synthesized, stored, and secreted by the juxtaglomerular cells of the kidney; it plays a role in regulation of blood pressure by catalyzing the conversion of the plasma glycoprotein angiotensinogen to angiotensin I. This, in turn, is converted to angiotensin II by an enzyme that is present in relatively ...
