...Bernard J. Carroll; James C. Ritchie; Hollister Rogers; Doh Kwan Kim Background: Using high-frequency blood sampling, we demonstrate glucocorticoid fast feedback (FF) mediated by endogenous cortisol in 6 normal humans. Methods: We stimulated adrenocorticotropic hormone (ACTH) secretion by ovine...

... has repeatedly reported that age aggravates HPA system changes [ 18,19 ]. That is, even subtle changes in the endocrine stress system are magnified by age. For this reason, we decided to only study elderly individuals. Adrenocorticotropic hormone Dexamethasone/corticotropin-releasing hormone...

... contributes to neuroendocrine activation under stress conditions. Moreover, the results show that listening to music may both positively and negatively influence the perception of stress and the level of anxiety, which might have functional consequences. Anxiety Stress Adrenocorticotropic hormone...

... are reflected by increased circulating levels of CRH and adrenocorticotropic hormone (ACTH) is unknown. Methods: LPS (100 µg/kg) was injected intraperitoneally in conscious rats, and blood processed for CRH using the new RAPID (reduced temperatures, acidification, protease inhibition, isotopic exogenous...

... in various locations, DA agonists have elicited some interest as a medical treatment for hypercorticism. Non-iatrogenic Cushing’s syndromes are due in 70% of the cases to a pituitary adrenocorticotropic hormone (ACTH)-producing adenoma, and, less frequently, to an adrenal adenoma or an ectopic ACTH secretion...

Here, we examine the kinetics and persistence of cardiovascular and locomotor responses to single and repeated immobilization stress (IMO), with and without prior treatment with adrenocorticotropic hormone (ACTH). Radiotelemetry probes were...

Longer-term effects of birth hypoxia on testosterone-related function were also assessed. Results: Rats born by C-section + 15 min of anoxia had...

... cytokines were obligatory for the stimulation of adrenocorticotropic hormone (ACTH) release by LPS. LPS and LPS-derived cytokines also stimulate the release of histamine (HA). HA is a known hypothalamic neurotransmitter and activates the HPAA. Therefore, to elucidate the role of HA in LPS- and cytokine...

... clear. We, therefore, sought to determine the effects of daily treatment with the DA receptor antagonist, domperidone (DOM), on secretion of the POMC peptides adrenocorticotropic hormone (ACTH) and α-melanocyte-stimulating hormone (α-MSH) from the dog pituitary, and on concentrations of another...

... administration. The purpose of this study was to determine the effects of endotoxin on pituitary hormone secretion both in vivo and in vitro in sheep, with emphasis placed on its effects on growth hormone (GH) release. Endotoxin (400 ng/kg i.v.) increased plasma GH, adrenocorticotropic hormone (ACTH), cortisol...

...Andreas Kjær; Ulrich Knigge; Flemming W. Bach; Jørgen Warberg Arginine vasopressin (AVP), corticotropin-releasing hormone (CRH) and catecholamines seem to be involved in the histamine- (HA) and/or stress-induced release of the pro-opiomelanocortin-derived peptides adrenocorticotropic hormone (ACTH...

...Thierry Chautard; Françoise Boudouresque; Viviane Guillaume; Charles Oliver During the postnatal period from day 2 to day 10 of life, basal and stress-induced adrenocorticotropic hormone (ACTH) and corticosterone releases are low as compared with adults. This period has been called the ‘stress...

In the present experiments, we have attempted to identify specific CNS regions mediating the feedback and to characterize which hypothalamic adrenocorticotropic hormone secretagogues are under glucocorticoid inhibitory control. Adrenalectomized rats were presented with a delayed...
