Human CRH resulted in a rapid stimulation of adrenocorticotropin and cortisol. Adrenocorticotropin levels increased from 6.8 ± 3.5 (± SD) pmoI/L (30.7 ± 16.1 pg/dL) to a peak of 11.6 ± 5.5 pmol/L (52.9 ± 24.8 pg/mL) at 15 min with return to baseline levels by 60 min. ...
BNST stimulation, on the other hand, produces behavioral consequences similar to those induced by forced restraint [14] whereas its chemical lesion prevents the development of behavioral deficits that characterize the "learned helplessness" phenomenon [19]. These deficits are thought to arise from ...

Thus, positive ACTH and cortisol responses to vasopressin analogs have been observed in the majority of patients with pituitary-dependent Cushing’s syndrome, whereas no such vasopressin tests had a lower diagnostic accuracy compared to the more widely used CRH test (5). Moreover, because of its...

CRH stimulation testACTHIn clinical guidelines, risk factors for a malignant illness course include 3 or more lifetime episodes of depression. Our aim was to investigate the activation of the hypothalamic–pituitary–adrenal hormonal axis in treatment–refractory affective disorder in pauciepisodic (one...
