...- fos or on nonapeptide mRNA expression was found in the hypothalamic paraventricular nucleus. Moreover, chronic PRL abolished the rise in plasma OXT induced by acute exposure to 30 min restraint stress in vehicle-treated rats. However, restraint stress did not significantly alter OXT or AVP mRNA...

...Richard R. Gala; Daniel J. Haisenleder Female Sprague-Dawley rats were ovariectomized, given estrogen, and blood samples were obtained via an atrial catheter in the afternoon during the prolactin (PRL) surge. Restraint stress applied at 16.00 h and continued for 3 h resulted in marked decrease...

... for pituitary prolactin (0.71 ± 0.04 for pituitary, vs. 0.19 ±0.06 in the hypothalamus; p < 0.001). Hypophysectomy, which led to the expected fall in serum prolactin to undetectable levels, and restraint stress, which resulted in a statistically significant 4-fold rise in serum prolactin, caused no change...

...-acetic acid (5-HIAA)] were measured in the suprachiasmatic (SCN), medial preoptic (MPO), and arcuate (AN) nuclei as well as the median eminence (ME) and striatum (ST) of the rat brain and correlated with changes in serum prolactin resulting from restraint stress (30 min) or the stimulus of acute suckling...

... to the extended response observed after acute stress, repeated restraint stress (30 min/day for 7 days) resulted in prepubertal males exhibiting a higher peak ACTH and corticosterone (free and total) response immediately following the stressor, but a faster return to baseline compared to adults [ 10 ]. We have...

... repeated forced swimming, or repeated forced swimming followed by repeated restraint stress. In neonatally androgenized females, immobility time was lower in the handled than in the non-handled rats, a pattern resembling that of the males, suggesting that the sexually dimorphic effect of handling...

... stress response by measuring corticotropin (ACTH), corticosterone, and testosterone levels in prepubertal and adult male rats exposed to a single 30-min session of restraint stress. We show that ACTH and corticosterone levels in prepubertal males take significantly longer to return to baseline after...

...; proestrus, n = 6) rats. Dialysates and blood samples were taken from 11.00 to 16.00 h in freely moving rats, but restraint stress was applied from 12.00 to 13.00 h. Basal ACh release in the hippocampus was low without significant differences between groups. Although ACh release promptly increased...
