Influence of Isoproterenol on the Plasma Renin Activity in Rats.
Woong Kyou Park, Yong Bae Shin, In soo Choi, Hyeon Suk Lee, Jung Soo Kim, Kyung Woo Cho

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...

There have been some suggestion that inactive renin may be a kind of precursor renin. There have not yet been however, founded direct evidence for that suggestion. To understand more about the physiological role of the plasma inactive renin, experiments have been done. The results obtained as follows. 1)In the newborn infants plasma renin activity showed highest level up to...
Change of Renal Excretion of Ascorbic Acid in Children.
Chang Yeal Jeon, Jong Duck Kim, Heon Sook Lee, Jung Soo Kim, Kyung Woo Cho
Clin Exp Pediatr. 1984;27(6):548-553.   Published online June 30, 1984
In order to investigate the development of renal function, especially of the capacity of reabsorption of ascorbic acid in proximal tubule, in function of aging, experiments have been done. 1)Urinary flow, creatinine and electrolytes excretion in children (age :1~13yrs, weight: 10~39 kg) increased by aging and reached near the adult value at 11~13 years old. 2) Urinary concentration ability was matured...
A Study on the Renal Function in Neonates and Children.
In Soo Choi, Young Sook Kim, Soo Chul Cho, Jung Soo Kim, Kyung Woo Cho
Clin Exp Pediatr. 1983;26(8):744-750.   Published online August 31, 1983
A study on the renal function and its changes by aging in neonates and children has been done, and the result obtained were as follow. 1) Urinary output, creatinine and electrolyte excretion in neonates (age: 12 〜 24 hrs) were significantly lower than children over 1 〜2 yrs, and urine concentrating ability may not yet t>e matured. 2) Urinary output, creatinine and electrolyte excretion in children...
Effects of Arginine Vasopressin on Renal Function in the Rabbit.
Dae Yeol Lee, Sun Taik Rhim, Jung Soo Kim, Kyu Cha Kim, Kyung Woo Cho
Clin Exp Pediatr. 1981;24(7):638-644.   Published online July 15, 1981
It has long been known that Vasopressin could increase the urinary sodium and chloride excretion. The exact mechanism and site of action, however, have not yet been explained. Experiments were performed whether the renal effects were the same in both cortical and juxtamedullary nephron in decorticated kiddney model. Heat-decortication was car ried out in the left kidney immersed in water...
Treatment of diabetes insipidus with chlorpropamide
Kibok Kim, Kyu-Hae Chung, Yang Hyun Park, Kyung Woo Cho, Young Johang Kook

In two cases of diabetes insipidus (a five-year-old girl and a eight-year-old boy), oral administration of chlorpropamide in doses of 125~250 mg per day produced marked antidiuresis and concentration of urine. It was noted that the agent was effective also in the vasopressin-insensitive case (8-year-old boy). During the treatment endogenous creatinine clearance and the amount of sodium excreted, as well...
