METABOLIC INDICATORS OF HYDRATION STATUS IN THE PREDICTION OF PAROTID SALIVARY-GLAND FUNCTION
Salivary glands require body fluids for normal function. It has been suggested that decreased levels of hydration (dehydration) may cause diminished salivary output, but it is not known whether salivary flow rates are related to biological measures of hydration status. The purpose of this study was to determine whether reduced parotid salivary flow rates, as [...]

ENDOCRINE AND RENAL RESPONSE TO WATER LOADING AND WATER RESTRICTION IN NORMAL MAN
1. Nine normal subjects (eight male, one female) on a fixed daily intake of 150 mmol of sodium and 80 mmol of potassium, were randomized to receive either 3 days of 1.0 litre total water intake/24 h (food + fluid) or 4 days of 6.8 litres total water intake/24 h, and were then crossed over [...]
RENAL MANAGEMENT OF SODIUM UNDER INDOMETHACIN AND ALDOSTERONE IN THE ELDERLY
The tubular handling of sodium in two groups of healthy old people, under the action of indomethacin and aldosterone was studied. Urinary aldosterone elimination was measured. From the results obtained, it is deduced that the elderly lose sodium through incompetence of the distal nephron. The possibility is put forward of a Na-K-ATPase deficit and/or interstitial [...]

BODY FLUID BALANCE IN DEHYDRATED HEALTHY OLDER MEN: THIRST AND RENAL OSMOREGULATION
We examined osmotic control of thirst and free water clearance in healthy older (65+, n = 10) and younger (Y, n = 6) subjects during a 3-h rehydration period after an approximately 2.4% decrease in body weight. Plasma volume (PV), plasma osmolality (Posm), renal function, and thirst were measured before and after dehydration and during [...]
HYPERHYDRATION: THERMOREGULATORY EFFECTS DURING COMPENSABLE EXERCISE-HEAT STRESS
This study examined the effects of hyperhydration on thermoregulatory responses during compensable exercise-heat stress. The general approach was to determine whether 1-h preexercise hyperhydration [29. 1 ml/kg lean body mass; with or without glycerol (1.2 g/kg lean body mass)] would improve sweating responses and reduce core temperature during exercise. During these experiments, the evaporative heat [...]
