TLDR
It was observed that the estrous cycles of 50% of the rats became desynchronized over the 5-day stress period; a steroid hormone imbalance is suggested as a possible factor contributing to this desynchrony.About:

Acute and chronic stress effects on open field activity in the rat: Implications for a model of depression
TL;DR: Chronic stressed rats showed endocrine changes similar to those seen in human depressives, and antidepressant treatment with the monoamine oxidase inhibitor pargyline restored the ability of chronically stressed rats to respond actively to stress.

Variations in the Hypothalamic-Pituitary-Adrenal Response to Stress during the Estrous Cycle in the Rat
Victor Viau,Michael J. Meaney +1 more
TL;DR: In this paper, the role of gonadal steroids in the hypothalamic-pituitary-adrenal (HPA) response to stress was investigated in cycling female rats.
Journal ArticleDOI
HPA function in adolescence: role of sex hormones in its regulation and the enduring consequences of exposure to stressors.
TL;DR: There is a growing evidence that exposure to stressors in adolescence may alter behavioural responses to drugs and cognitive performance in adulthood, however, the effects reported appear to be stressor-specific and sex-specific.

Sex Differences in the HPA Axis
TL;DR: This review focuses on the interactions between the gonadal hormone system and the HPA axis as the key mediators of these sex differences, whereby androgens increase and estrogens decrease HPA activity in adulthood.
Journal ArticleDOI
Social stress increases the acquisition of cocaine self-administration in male and female rats
TL;DR: Social status appears to be a potent influence in the onset of drug taking behavior in both male and female rats, and rats that had experienced social stress self-administered more cocaine than non-defeated controls.

A simple fluorimetric method for the estimation of free 11-hydroxycorticoids in human plasma.
TL;DR: A simple fluorimetric method is described for measuring free 11-hydroxycorticoids in human plasma that compares favourably with the methods in current use for estimating urinary steroids, and has the added advantage of not being dependent on the accurate collection of 24-hour urine samples.

Population density and social pathology.
TL;DR: In a series of experiments normal colonies of Norway rats were allowed to grow unchecked in a limited environment as discussed by the authors, and four distinct types of behavior emerged: 1) In the end pens which were easily defended dominant males set up harems.
Journal ArticleDOI
Effect of "stress" on serum prolactin and luteinizing hormone levels during the estrous cycle of the rat.
TL;DR: Compared to decapitation, laparotomy and bleeding under ether anesthesia induced 3- to 8-fold increases in serum prolactin values at all times studied dur-ing the estrous cycle except on the afternoon of proestrus, when no further increase in already elevated levels was observed.
Journal ArticleDOI
Parameters of novelty, shock predictability and response contigency in corticosterone release in the rat.
TL;DR: Exposure of male C.F.S. rats to novel apparatus raised plasma corticosterone levels, but the effect habituated, and the role of psychological component in psychosomatic stress and possible neuroendocrine pathways in psychological stress were discussed.

Plasma corticosterone response to parameters of electric shock stimulation in the rat
TL;DR: It was found that merely placing the animals in the experimental cage increased corticosterone levels, and these levels were further elevated as shock intensity and duration were increased.
