Neuroendocrine function, assessed in 90 couples during their first year of marriage (Time 1), was related to marital dissolution and satisfaction 10 years later. Compared to those who remained married, epinephrine levels of divorced couples were 34% higher during a Time 1 conflict discussion, 22% higher throughout the day, and both epinephrine and norepinephrine were 16% higher at night. Among ...

Objective(s): To investigate the effects of paeoniflorin (PEF) on the hypothalamic-pituitary-adrenal (HPA) axis feedback function of post-traumatic stress disorder (PTSD). cSingle-prolonged stress (SPS) was used to establish a PTSD-like rat model. The contents of plasma corticosterone (CORT), adrenocorticotropin hormone (ACTH) and cortic...

By means of direct arterial perfusion of the adrenal glands of the hypophysectomized dog, it has been shown that synthetic lysine, arginine and acetyl arginine vasopressins stimulate the adrenal cortex directly to secrete hydrocortisone. Pressor activity and cortisol-stimulating activity were demonstrated to be independent of each other. Similar polypeptides, such as oxytocin, insulin, glucagon...

The present studies were designed to examine the effect of angiotensin II on baroreflex control of adrenocorticotropic hormone secretion and heart rate in conscious dogs. Baroreflex function was assessed by examining the relationship between blood pressure and plasma corticosteroid concentration (used as an index of adrenocorticotropic hormone secretion) and between blood pressure and pulse int...

INTRODUCTION The diagnostic efficacy of biochemical and imaging modalities for investigating the causes of Cushing's syndrome are limited. We report a case demonstrating the limitations of these modalities, especially the inability of functional imaging to help localize the site of ectopic adrenocorticotropic hormone secretion. CASE PRESENTATION A 37-year-old Arabian woman presented with 12 m...

INTRODUCTION Determining the etiology of Cushing's syndrome is very challenging to endocrinologists, with most of the difficulty arising from subtype differentiation of adrenocorticotropic hormone-dependent Cushing's syndrome. We present the pitfalls of evaluating a rare cause of adrenocorticotropic hormone-independent Cushing's syndrome in the transition period between adolescence and adulthoo...
