Water Intake of the Rat as a Function of Duration of Water Deprivation

Psychological Reports, 1966
Water intake in a 2-hr. period was measured for groups of rats deprived of water either 0, 12, 24, 36, 48, 72, 96, 120, 144, or 168 hr. The intake function appeared to reach a maximum value at 48 hr., suggesting that intake is not a useful measure of the effects of long durations of water deprivation.

Water Deprivation: A New Migraine Precipitant

Headache: The Journal of Head and Face Pain, 2005
Fifty 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, 1958
There 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, 1968
In 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, 1979
Radioiron 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, 1986
Four-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.

Naloxone: Effects on food and water consumption in the non-deprived and deprived rat

Psychopharmacology, 1980
Naloxone (0.5--5 mg/kg) reduced both food and water intake in non-deprived male rats, tested in the dark phase of the light-dark cycles in their home cages. These effects were transient; food and water-intake were restored to control levels by the end of the 8-h test period. The effects were also not dose-related.

The Effect of Food and Water Deprivation and Satiation on Recognition

The American Journal of Psychology, 1979
Food and water deprived and satiated subjects, as well as control subjects, were shown words presented tachistoscopically for .01 sec until word recognition. Five food-relevant, five water-relevant, and five neutral (animal) words of high string frequency were matched for letter confusability and letter predictability. Analyses of the data, in terms of

Effects of water deprivation on the pharmacokinetics of metformin in rats

Biopharmaceutics & Drug Disposition, 2007
AbstractIt was reported that metformin was mainly metabolized via hepatic CYP2C11, 2D1 and 3A1/2 in rats, and in a rat model of dehydration, the expressions of hepatic CYP2C11 and 3A1/2 were not changed. Hence, it could be expected that the Clnr of metformin is comparable between two groups of rats if the contribution of CYP2D1 in the rat model of ...

Learned aversion to mannitol in water-deprived rats

Physiology & Behavior, 1984
Mannitol, a non-absorbent compound may suppress free drinking in rats. It was suggested that the osmotic accumulation of water in the intestine produced a satiety signal by distending the wall of the gut, which resulted in the reduction of intake. However, we never obtained this suppression during the first exposure to mannitol in water deprived rats ...
