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 [...]
THIRST
The homeostasis of body fluid traditionally is viewed as involving the regulation of its osmolality and of blood volume. However, the control of thirst is more complex than can be described in a two-factor model, [...]
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 [...]
