Adaptation to repeated restraint stress in rats: failure of ethanol-treated rats to adapt in the stress schedule.
Adaptation to a repeated restraint stress schedule was monitored in ethanol-treated and control rats. A single episode of 2 h restraint decreased food intake in both control and ethanol-treated rats. The decreases in control rats were not observed following the 5th daily restraint of 2 h/day, suggesting that adaptation has occurred. Ethanol-treated rats, however, exhibited decreased food intake...
متن کاملEffects of repeated restraint stress on gastric motility in rats.
In our daily life, individuals encounter with various types of stress. Accumulation of daily life stress (chronic stress) often causes gastrointestinal symptoms and functional gastrointestinal diseases. Although some can adapt toward chronic stress, the adaptation mechanism against chronic stress remains unknown. Although acute stress delays gastric emptying and alters upper gastrointestinal mo...
متن کاملEnergetic response to repeated restraint stress in rapidly growing mice.
There is a cost of stress that may result in the loss of normal biological function (e.g., growth). Repeated, and even single, applications of stressors have been shown to induce negative energy balance in rodents. However, here we addressed whether this energetic response changes during multiple stress exposure and whether there is complete recovery subsequent to the cessation of stress exposu...
متن کاملVasopressin and corticotropin-releasing hormone gene responses to novel stress in rats adapted to repeated restraint.
Stress-responsive neurons of the hypothalamic paraventricular nucleus (PVN) show functional plasticity and adapt to repeated restraint (RR) stress. To investigate whether neuronal adaptation to the homotypic stress also affects their response to a heterotypic stressor, we used in situ hybridization with intronic and exonic probes to measure primary transcript (hnRNA) and messenger RNA (mRNA) le...
متن کاملChronic disruption of body weight but not of stress peptides or receptors in rats exposed to repeated restraint stress.
Rats exposed to restraint stress for 3 h on each of 3 days lose weight and do not return to the weight of their non-stressed controls for extended periods of time. Studies described here demonstrate that the initial weight loss is associated with increased energy expenditure and reduced food intake on the days of restraint but that there is no difference between stressed and control rats once s...
