Jae Hong You, Jae Ho Lee
Clin Exp Pediatr. 1989;32(9):1232-1239.   Published online September 30, 1989
Thes is a study on changes of plasma renin activity (PRA) and aldosterone concentration (PAC) which was obtained before and after heart operation in 26 normotensive children with congenital heart diseases without renal disease admitted in Chungnam National University Hospital for cardiac catheterization with angiogram and heart operation from Apr. 1988 to Aug. 1988 to confirm any differences of PRA and PAC between groups...
Plasma Renin Activity (PRA) in Peripheral Vein and Renal Veins in Normotensive Children with Cyanotic Congenital Heart Disease.

Clin Exp Pediatr. 1988;31(8):1021-1027.   Published online August 31, 1988
PRA’s in peripheral vein, both renal veins, and inferior vena cava (IVC) were measured in 25 normotensive children without renal disease undergoing cardiac catheterization for their underlying cyanotic congenital heart disease. And we presented the results as reference values/ranges of PRA in children. 1) There was no significant difference in PRA between both side renal veins at any absolute PRA levels with a mean ratio (RT/LT)...
Periperal Plasma Renin Activity in Children with Normotensive Reflux Nephropathy.
Chong Guk Lee, Kwang Mann Ko
Clin Exp Pediatr. 1988;31(6):731-737.   Published online June 30, 1988
Peripheral renin activity was measured in 11 children with normotensive reflux nephropathy and 20 normal children to disclose the abnormality of the renin-angiotensin system in the patient group. 9 children among the patient group were allocated to single-dose captopril test for the assessment of the response to the test in patients with normotensive reflux nephropathy. 1. Contrary to the significant negative correlation between PRA and...
Plasma Renin Acivity in Children with Acute Glomerulonephritis and Nephrotic Syndrome.
Oh Kyun Kwon, Young Hun Chung
Clin Exp Pediatr. 1987;30(11):1213-1220.   Published online November 30, 1987
This is a study on plasma renin acitivity (PRA) which was obtanined from the patients with acute glomerulonephritis or nephrotic syndrome and normotensive control group admitted in Chungnam National University Hospital from Oct. 1985 to Aug. 1986 to confirm any differences of PRA between groups and to establish their influencing factors. The results were as follows; 1) PRA of noimal children in preschool age (3.49 ±0.98...
Studies on the Changes of Serum Osmolality Electrolytes, Digoxin-like Substance and Plasma Renin Activity Following Angiocardiography using Hypertonic Contrast Media.

Angiocardiography and cineangiocardiography have been employed with increasing frequency for the diagnosis of cardiovascular diseases. These commonplace technics of cardiovascular radiology depend upon the rapid injection of hypertonic contrast media into the heart or central circulation. In order to study the effects of concentrated radiopaque materials(Conray®, 1382 mOsm/L, 1-2 ml/ kg) on hemodynamic consequences, the changes of serum osmolality, sodium, potassium, chloride, digoxin-like substance and...
Influence of Isoproterenol on the Plasma Renin Activity in Rats.

It has been suggested that the effect of catecholamine administered into the renal artery on the plasma renin activity may be controlled by extrarenal beta-receptor. Still the exact mechanism responsible for the increase of the plasma renin activity by catecholamines is obscure. In this experiment I have intended to clarify the involvement of extrarenal beta-receptor concerning renin release in the...
Plasma Renin Activity (PRA) in Peripheral Vein and Renal Veins in Normotensive Children.
Chong Ku Yun, Hae Il Cheong, Chung Il Noh, Jung Yun Choi, Yong Choi, Kwang Wook Ko, Kyung Mo Yeon
Clin Exp Pediatr. 1985;28(6):555-563.   Published online June 30, 1985
PRA in peripheral vein, both renal veins and both inferior vena cava (JVC) both proximal and distal to the drainage of the both renal veins was measured in 80 normotensive children with no renal disease undergoing routine cardiac catheterization due to congenital heart disease which did not cause significant hemodynamic changes in most of them. And we presented the results...
