Abstract |
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 (age: 1 〜 10 yrs) increased
l)y aging, and reached near the adult value at 9〜 10 yrs old. 3) Urine concentrating ability and sodium, chloride reabsorptive capacity were almost matu-red at 3 〜4 yrs old.
4) Circardian rhythm in the renal function seemed to be matured already at 1 〜4 yrs of age, and its function was supressed during the night. 5) There was intimate intercoorelationship between nocturnal and 24 hrs renal function, so the findings of nocturnal urine could be used as an index of renal function.
