Body temperature, urine output, osmotic and free water clearances, plasma osmolality, sodium and potassium concentrations, blood lactate level, osmotic thirst and central blood volume were measured in dogs exposed to cold (+1 to -8 degrees C) for 1-3 hours and compared to those obtained under control conditions at ambient temperatures (18-20 degrees C).

The purpose of the present study was to investigate the possible role of vasopressin (ADH) in the control of thirst. With this aim spontaneous water intake (WI) was examined in conscious dogs after 1) electric stimulation in the basal forebrain causing release of ADH, 2) injection of 0.03, 0.05, 0.10, 0.15, 0.30, and 3.00 mU of ADH into the third cerebral(More)
Diuresis and water intake was determined in 20 male albino rats during 8 weeks of immobilization and in 10 rats in post-immobilization recovery phase. Increase of diuresis and water intake during the immobilization period have been observed. Neither changes in sodium and potassium excretion nor in Na/K ratio were found. As the immobilization of the rats did(More)
Seven dogs were chronically implanted with 30 electrodes directed at various structures of the basal forebrain. Osmotic thirst threshold (expressed as an increase in plasma osmolality and a decrease in cellular water content caused by an intravenous infusion of 5% NaCl, necessary to induce drinking) was measured during electric stimulation of the basal(More)
Body temperature, water intake, urine output, sodium and potassium excretion, osmolal and free water clearance, plasma osmolality, sodium and potassium concentrations and osmotic thirst were examined in conscious dogs during pyrogen fever and compared to those found under control conditions. Arterial blood pressure and central venous pressure were also(More)
The effect of electrical brain stimulation (ESB; 50 Hz, 50-150 microA sine wave, 5 s on/5 s off) on osmotic thirst was examined in 10 conscious dogs chronically implanted with electrodes aimed at the anteromedial part of the basal forebrain. Suppression of osmotic thirst (SOT) was observed during stimulation through 18 of 41 electrodes located in the(More)
To determine whether centrally released vasopressin influences thirst, observations of osmotic thirst threshold, osmotic load excretion and postloading restitution of plasma osmolality were made in dogs in control experiments and during infusion of AVP antagonists into the third ventricle. Significant elevation of osmotic thirst threshold was elicited by(More)
