The Effect of High Dose Total Body Irradiation on ACTH, Corticosterone, and Catecholamines in the Rat [PDF]

, 2011
Total body irradiation (TBI) or partial body irradiation is a distinct risk of accidental, wartime, or terrorist events. Total body irradiation is also used as conditioning therapy before hematopoietic stem cell transplantation.

Radioimmunoassay of plasma renin activity.

Clinical Chemistry, 1976
Abstract We describe a sensitive, simplified radioimmunoassay method for determination of plasma renin activity. Plasma was acidified to the optimal pH (6.0) of angiotensin l generation with the least possible dilution, by using a single addition of hydrochloric acid and the enzyme inhibitor hydroxyquinoline.

Performance of renin assays in selecting fludrocortisone dose in children with adrenal disorders

Endocrine Connections
Children with salt-wasting adrenal insufficiency are managed with glucocorticoid and mineralocorticoid replacement. Measurement of renin activity or concentration alongside blood electrolyte levels is used to monitor the adequacy of mineralocorticoid ...

Secondary Hypertension due to a Renin-secreting Juxtaglomerular Cell Tumor

Journal of the Formosan Medical Association, 2010
A juxtaglomerular cell tumor (JCT) is a rare, renin-secreting tumor of the kidney and can cause hypertension. JCT is pathologically benign, and resection of the tumor is curative for hypertension.

Different behaviour of the N-terminal and C-terminal fragment of proatrial natriuretic factor in plasma of healthy subjects as well as of patients with cirrhosis [PDF]

, 1990
N-terminal (atrial natriuretic factor (ANF) 1-98) and C-terminal (ANF 99-126) fragments of proatrial natriuretic factor (NTA and CTA, respectively) were determined in plasma of healthy subjects adopting different postures and in patients with cirrhosis ...

Regulation of Renin Release via Cyclic ADP-Ribose-Mediated Signaling: Evidence from Mice Lacking CD38 Gene

Cellular Physiology and Biochemistry, 2013
Background/Aims: Despite extensive studies, the intracellular regulatory mechanism of renin production and release is still poorly understood. The present study was designed to test whether CD38-ADP-ribosylcyclase signaling pathway contributes to the ...

Effect of Breed on Plasma Endothelin‐1 Concentration, Plasma Renin Activity, and Serum Cortisol Concentration in Healthy Dogs

Journal of Veterinary Internal Medicine, 2016
Background There are breed differences in several blood variables in healthy dogs. Objective Investigate breed variation in plasma endothelin‐1 (ET‐1) concentration, plasma renin activity, and serum cortisol concentration. Animals Five‐hundred and thirty‐

Reduced blood pressure in sickle cell disease is associated with decreased angiotensin converting enzyme (ACE) activity and is not modulated by ACE inhibition.

PLoS ONE, 2022
BackgroundSickle cell disease (SCD) incurs vaso-occlusive episodes and organ damage, including nephropathy. Despite displaying characteristics of vascular dysfunction, SCD patients tend to present relatively lower systemic blood pressure (BP), via an ...

Measurement of Renin Activity in Human Plasma [PDF]

Circulation Research, 1965
A method is described for estimating plasma renin activity by using renin substrate present in plasma. This method differs from other indirect renin assay methods by (1) incubation in the absence of ions thus establishing conditions for zero order kinetics for the reaction between endogeneous renin and substrate and (2) the use of ...

Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]

, 1990
In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...
