Water Deprivation and Trichloroethylene
Archives of Environmental Health: An International Journal, 1970Rats with implanted hypothalamic electrodes were trained to press a lever for electrical brain stimulation during a daily 30 minute test period. In rats continuously deprived of water for three days, the rate of lever-pressing declined slightly on the first day but remained at that level during the next two days.

Thirst following water deprivation in dogs
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1977Eight dogs were prepared with unilateral carotid loops, and trained to stand quietly in a modified Pavlov stand. They were deprived of water for 24 h, which significantly depleted both the cellular and extracellular fluid (ECF) compartments. When they were allowed access to water for 5 min, they promptly drank amounts sufficient to make up their fluid

Influence of Water Deprivation on Adrenocortical Rhythms
Neuroendocrinology, 2008Female rats maintained on a 23 h water deprivation schedule show an altered circadian rhythm of pituitary-adrenal activity. Significant elevations of plasma corticosterone are observed in the morning if the watering time is between 1000 and 1100 h. These elevations continue to early afternoon if watering occurs at 1500 h. The normal late afternoon peak

In patients with polyuria, the response of both urine osmolality and output to water deprivation differentiates conditions of overhydration from diabetes insipidus, as long as osmotic diuresis and chronic renal failure have been excluded.

Water Deprivation: A New Migraine Precipitant
Headache: The Journal of Head and Face Pain, 2005Fifty migraineurs were asked if insufficient fluid intake could provoke their migraine attacks. Twenty replied “yes,” 7 were doubtfully positive, and 23 said “no.” In addition 14 of 45 migraineurs at a meeting of the British Migraine association (UK) also recognized fluid deprivation as one of their migraine triggers.

Light Reinforcement as a Function of Water Deprivation
Psychological Reports, 1958There are several studies (3, 4, 5 ) which attest to the efficacy of light as a reinforcing stimulus with non-deprived animals. However, Kling, et al. ( 5 ) noted that light presentation did not appear to strengthen bar pressing when the subjects, albino rats, were water deprived.

Effects of water deprivation on the water content of cattle skin
International Journal of Biometeorology, 1968In cattle the water content of the skin was determined (1) in the normal animals; (2) after a 3-day period of water deprivation (dehydration); (3) one hour after the water deprived animals had resumed drinking (rehydration)and (4) one hour after the beginning of infusion of water into the rumen of normal animals (overhydration). Dehydration reduced the

Mechanism of the Decreased Erythropoiesis in the Water Deprived Rat
British Journal of Haematology, 1979Radioiron uptake by erythrocytes, metabolic rate, erythropoietin formation during hypoxia and erythroid responsiveness to exogenous erythropoietin were determined in both starved and water deprived rats. The feed intake showed a marked and progressive reduction during water deprivation.

Interaction of mercury and water deprivation on the hematology of chickens
Journal of Toxicology and Environmental Health, 1986Four-week-old male chickens were subjected to one of the following treatments: 0 ppm mercury (Hg) plus water ad libitum, 0 ppm Hg plus limited water (LW), 500 ppm Hg plus water ad libitum, and 500 ppm Hg plus LW. Exposure was for each of the following time intervals: 0-3, 0-6, 0-9, 0-12, and 0-15 d.
