HYPOHYDRATION EFFECT ON FINGER SKIN TEMPERATURE AND BLOOD FLOW DURING COLD-WATER FINGER IMMERSION
This study was conducted to determine whether hypohydration (Hy) alters blood flow, skin temperature, or cold-induced vasodilation (CIVD) during peripheral cooling. Fourteen subjects sat in a thermoneutral environment (27 degrees C) during 15-min warm-water (42 [...]
Relative density of urine: methods and clinical significance.
The physical properties and chemical composition of urine are highly variable and are determined in large measure by the quantity and the type of food consumed. The specific gravity is the ratio of the density [...]
EFFECTS OF VOLUNTARY FLUID INTAKE DEPRIVATION ON MENTAL AND PSYCHOMOTOR PERFORMANCE
AIM: To assess if there is deterioration in mental and psychomotor performance during 24-hour voluntary fluid intake deprivation. METHODS: A battery of computer generated psychological tests (Complex Reactionmeter Drenovac-series) was applied to 10 subjects to [...]
Disordered water metabolism: hyponatremia.
Normal osmoregulation is maintained by the proper function and interplay of factors influencing thirst, renal water metabolism, and vasopressin secretion. In pathophysiologic states, body water homeostasis is disrupted and hyponatremia ensures. Hyponatremia associated with cardiac [...]
