THE INFLUENCE OF AGE ON THE RENAL RESPONSE TO WATER DEPRIVATION IN MAN
Alterations in urine concentrating ability with age were examined in 98 active community-dwelling volunteers (aged 20-79 years) who were free from evidence of diseases known to adversely affect renal function. There was a significant decrease [...]
VOLUNTARY HYPOHYDRATION IN 10- TO 12-YEAR-OLD BOYS
This study was performed to determine whether a) children voluntarily dehydrate while exercising in hot climate; b) such dehydration affects their well-being and thermoregulation. Eleven 10p to 12-yr old, partially acclimatized boys underwent two work-in-the-heat [...]
VALIDATION OF THE DEUTERIUM DILUTION TECHNIQUE FOR THE MEASUREMENT OF FLUID INTAKE IN INFANTS
The validity of the deuterium dilution technique as a method of measuring fluid intake was investigated by comparing values obtained with this technique and direct measurements of milk intake in 10 exclusively bottle-fed infants recovering [...]
AGE-RELATED FAILURE OF VOLUME-PRESSURE-MEDIATED VASOPRESSIN RELEASE
Osmoreceptor sensitivity, as estimated by the plasma vasopressin (AVP) response to hypertonic saline infusion, increases with age. We studied volume-pressure sensitivity, as estimated by the plasma AVP response to orthostasis, in healthy young (19-31 yr [...]
