Plasma Cryoactivated Renin and Active Renin in Diabetes Mellitus*

The Journal of Clinical Endocrinology & Metabolism, 1981
PRA and the inactive renin which is activated by cold (IR-C) were studied in a group of normal subjects and in patients with diabetes mellitus with and without the presence of nephropathy. The amount of renin activity, as measured after incubation of plasma at -5 C for 4 days, was called cold renin activity (CR.

Suppression of Plasma Renin Activity by Cyclosporine

Journal of Urology, 1987
Cyclosporine treatment is associated with hypertension and suppression of plasma renin activity, the causes of which are unclear. To determine whether suppressed plasma renin activity is due to extracellular fluid volume expansion, 10 cyclosporine-treated renal transplant recipients were compared with 10 azathioprine-treated renal transplant recipients

Active renin versus plasma renin activity to define aldosterone-to-renin ratio for primary aldosteronism

Journal of Hypertension, 2004
In recent years, the assessment of the plasma aldosterone-to-renin ratio (ARR) has become an established screening method for the diagnosis of primary aldosteronism. Plasma renin activity (PRA) is usually measured to define ARR although, increasingly, renin concentration alone is often measured in clinical routine.To determine the threshold of ARR ...

Circadian Variations of Total Renin, Active Renin, Plasma Renin Activity and Plasma Aldosterone in Clinically Healthy Young Subjects

Hormone and Metabolic Research, 1990
The direct assay of total renin (TRC) and active renin concentration (ARC) is a reality due to the availability of monoclonal antibodies against human renin. Because of this, a study has been performed in order to assess the circadian rhythmicity of TRC and ARC. The study was extended to plasma renin activity (PRA) and plasma aldosterone concentration (

Measurement of Plasma Renin Activity

2013
This chapter describes the measurement of plasma renin activity by calculation of the quantity of angiotensin I that is released in plasma by the action of endogenous enzyme renin on angiotensinogen, the endogenous substrate. Details are given for the generation of angiotensin I from plasma using controlled pH and temperature conditions.

PLASMA RENIN ACTIVITY IN CHRONIC NEPHROPATHY

Acta Medica Scandinavica, 1970
Abstract. Plasma renin activity (PRA) has been measured in 14 patients with chronic nephropathy maintained on hemodialysis. Most of the patients were hypertensive at the time of measurement, and mean PRA was significantly elevated. No correlation between PRA, mean blood pressure and dialytic controllability of hypertension could be established.

Measurement of Plasma Renin Activity

2006
Measurement of angiotensin 1, released in plasma by the action of endogenous enzyme renin on endogenous substrate, angiotensinogen is described. Details are given for the generation of angiotensin 1 from plasma using controlled conditions of pH and temperature.

Plasma Renin Activity

1994
Renin is a proteolytic enzyme (M.Wt. 40 kDa) released by the juxtaglomerular cells of the kidney in response to sympathetic neural activity, dehydration, or salt loss.

PLASMA RENIN ACTIVITY IN PANHYPOPITUITARISM

Acta Endocrinologica, 1972
ABSTRACT The response of plasma renin activity (PRA) to sodium restriction, furosemide and ACTH administration were studied in six patients with panhypopituitarism of various causes and in a patient with Addison's disease. In all the patients with panhypopituitarism, the basal levels of PRA were within normal limits and the responses of PRA and

RADIOIMMUNOASSAY DETERMINATION OF PLASMA-RENIN ACTIVITY

The Lancet, 1969
Abstract Both practical and theoretical considerations have made difficult the application of a recently developed angiotensin II immunoassay to the measurement of " plasma-renin activity ", and a separate radioimmunoassay for angiotensin I has therefore been developed.
