...Sarah A. Jacob; David D. Williams; Jennifer Boyd; Kavitha Dileepan; Sarah L. Tsai Introduction: Patients with suspected adrenal insufficiency undergo screening with a serum morning cortisol level and confirmatory testing with an adrenocorticotropic hormone (ACTH) stimulation test. However, much...

...P. Chiodera; R. Volpi; L. Capretti; G. Giacalone; G. Caffarri; C. Davoli; E. Nigro; V. Coiro Delta-sleep-inducing peptide (DSIP) is a well-known inhibitor of pituitary ACTH secretion. In order to evaluate the possible influence of DSIP on basal arginine-vasopressin (AVP) secretion and/or on the AVP...

...A. Ait-Chaoui; J. Rakotondrazafy; R. Brudieux Age related changes in the time courses of response of plasma corticosterone and aldosterone to exogenously applied ACTH were simultaneously studied in old (female and male) Long-Evans rats and compared to both young and adult pentobarbitone...

... of the autonomous adrenocorticotropic hormone (ACTH) hypersecretion in the pituitary. Hormonal evaluation suggested a pituitary genesis for the disease, but both sellar computed tomography and cranial magnetic resonance (MR) were unable to give clear-cut evidence for a pituitary neoplasm. Simultaneous and bilateral...

...P.P. Vescovi; V. Coiro; R. Volpi; M. Passeri In order to establish possible alterations in the hypothalamic pituitary-adrenal axis and in ACTH-related opioids in cocaine addicts, plasma ACTH, cortisol and β-endorphin levels were measured throughout the day in 9 cocaine addicts [age: 27 ± 5 years...

... (S) secretion and induces an IGF-I responsiveness to the ACTH challenge. The aim of the present study was to further investigate the mechanisms by which IGF-I is secreted after ACTH challenge in children affected with IGHD by correlating IGF-I versus cortisol (F) time courses after ACTH...

Chiodera The possible mediation of dopaminergic, muscarinic cholinergic and/or serotonergic receptors in the response of ACTH/cortisol to metoclopramide (MCP) was evaluated in 27 normal...

...M.C. Young; K.M. Laurence; I.A. Hughes A comparative study of adrenal morphology between normal fetuses and those with anencephaly or congenital adrenal hyperplasia (CAH) was performed in order to examine the hypothesis that fetal adrenal mass and structure are adrenocorticotrophin (ACTH)-dependent...

These abnormalities observed during discontinuance of alcohol consumption may reflect adaptive mechanisms of the hypothalamicpituitary-adrenal activity which may be previously altered by chronic alcohol intoxication. 28 11 2008 o-CRF test Cortisol ACTH...

...Lubomir J. Valenta; Alan N. Elias; Harvey Eisenberg Epinephrine (E) and norepinephrine (NE) levels were measured simultaneously in the adrenal veins of 6 patients before and after stimulation with 0.25 mg β1-24 ACTH. In 1 patient with Cushing’s syndrome, E and NE were also measured before and 30...

...Roger A. Cheitlin; Manfred Westphal; Claudia M. Cabrera; Dennis K. Fujii; James Snyder; Paul A. Fitzgerald A 59-year-old man developed Cushing’s syndrome with massive bilateral adrenal macronodular hyperplasia. Plasma ACTH levels were undetectable both peripherally and in the inferior petrosal...

...J.B. Baumann; J. Girard; E. Christen; A.N. Eberle; W. Ruch 16- and 4-week-old intact and adrenalectomized rats have been treated with different doses of the three glucocorticoids hydrocortisone, prednisolone and dexamethasone by gavage. The delayed feedback effect on plasma ACTH and corticosterone...

...Barry M. Sherman; Janet A. Schlechte; Bruce M. Pfohl We examined the plasma cortisol and ACTH concentrations after graded doses of dexamethasone in a group of young, healthy adults. The decrease in cortisol was uniform in all subjects, and in 8 subjects there was a high degree of correspondence...

...Charles Eldridge; John R. Lymangrover Prolactin, alone and in combination with ACTH, was tested for its ability to release steroids from rat adrenocortical slices superfused in vitro. The hormone possessed weak activity alone (minimal responsive dose = 1 U), but was able to potentiate the ACTH...

...E.C. Degli Uberti; G. Trasforini; A.R. Margutti; C.A. Rotola; R. Pansini The possible role of gastrin on TSH, ACTH and cortisol secretion was evaluated by intravenous administration of pentagastrin, the carboxyl-terminal tetrapeptide of gastrin (0.5 µg/kg b.w.) into 12 healthy subjects...

...Felice Petraglia; Fabio Facchinetti; Donatella Parrini; Giuseppe Micieli; Salvatore De Luca; Andrea R. Genazzani The major objective of this study was to investigate the analogy existing between the typical circadian periodicity of ACTH and that recently described of β-lipotropin (β-LPH) and β...
