Anorexia, food deprivation and hibernation

Physiology & Behavior, 1974
Abstract Two experiments examined the relationship between food eaten and the lenghts of bouts of continuous hibernation of golden-mantled ground squirrels, Citellus lateralis , kept at 5 ± 4°C. The first experiment showed that food deprivation at the start of the hibernation season increased the hibernation bout lengths compared to a control group ...

Bradycardia in cattle deprived of food

Journal of the American Veterinary Medical Association, 1990
Summary Bradycardia was documented in 12 cattle from which food had been withheld for 48 hours in preparation for general anesthesia and an elective surgical procedure. The heart rates decreased by a mean of 14 beats/min, and 4 cows had sinus arrhythmia.

Food deprivation and cocaine self-administration

Pharmacology Biochemistry and Behavior, 1981
The effects of food deprivation on the self-administration of cocaine were assessed in three rhesus monkeys under different schedules of reinforcement. In one subject, decreasing body weight to 80% of free-feeding weight (ffw) resulted in increase response rates and number of cocaine infusions taken.

Intracerebroventricular enterostatin stimulates food intake in non-food-deprived rats

Peptides, 1996
Previous studies reported that ICV enterostatin reduced high-fat food intake in food-deprived rats. The present study sought to determine if ICV enterostatin would decrease intake of a high-fat food in non-food-deprived rats. Eight doses (0-32 micrograms) were tested.

Food deprivation facilitates hypothalamic drinking

Physiology & Behavior, 1970
Abstract Rats were implanted with chronic electrodes in the lateral hypothalamic drinking area and were maintained on ad lib water. One to three days of food deprivation slightly decreased the minumum amout of current necessary to induce the water-satiated rats to drink.

Food deprivation and ethanol intake

Drug and Alcohol Dependence, 1980
Results from our laboratory show that food deprivation (reducing animals to 80% of free-feeding weight) markedly increases rats’ oral and intravenous intake of the potent opioid, etonitazene. Additionally, food deprivation greatly increases rhesus monkeys’ oral intake of phencyclidine and pentobarbital once these drugs have been established as ...

Dieting, Perceived Deprivation, and Preoccupation with Food

Western Journal of Nursing Research, 2003
A prospective study using 14-day food diaries was conducted to determine whether perceived deprivation and preoccupation with food correspond to actual caloric and fat intake, using a sample of 121 adult women who were binge eating without purging or were currently dieting. Caloric and fat intake were not significantly related to perceived deprivation.

Food Deprivation Reduces Rats' Oil Preference

Appetite, 1993
Rats normally prefer dilute oil suspensions over vehicle, but this preference can be abolished by exposing them to dilute oil suspensions during a period of food deprivation. In the first series of experiments, rats were given a choice of 0.5-0.9% triolein vs. vehicle for 4 consecutive days each week for 3 weeks. Food was available ad libitum on days 1,

Food deprivation and effort expended for food

Learning and Motivation, 1970
Abstract Wheel turning by rats was studied under several conditions of food deprivation. Two procedures were compared, one in which force required to turn the wheel remained constant throughout a session and one in which required force increased progressively with each revolution of the wheel.

Food deprivation and surfactant in adult rats

Journal of Applied Physiology, 1983
We sought to determine if fasting (80% reduction of food intake for 72 h) diminishes airway or tissue disaturated phosphatidylcholine (DSPC) relative to alveolar surface area, or alters the lung response to overventilation. The lungs of fasted rats were lighter, but the size and recoil of saline-filled lungs, and the alveolar surface area of lungs ...
