Studies on the corticotrophin-releasing activity of vasopressin, using ACTH secretion by cultured rat adenohypophyseal cells.

Endocrinology, 1976
CRF activity of synthetic vasopressins and pitressin was studied in an in vitro system of cultured rat adenohypophyseal cells using direct measurement of ACTH by radioimmunoassay.

Vasopressin in the ICU

Current Opinion in Critical Care, 2004
Vasopressin is one of the most important endogenously released stress hormones during shock. In this review, studies published in the past year that add to our understanding of the use of vasopressin in the ICU are discussed.Endogenous vasopressin levels are inappropriately low in adults with severe sepsis but not in children with meningococcal septic ...

Pituitary adenomas that caused Cushing's disease or Nelson's syndrome are not responsive to ovine corticotropin-releasing factor in vitro.

Journal of Clinical Endocrinology and Metabolism, 1983
The response of pituitary adenomas obtained surgically from patients with Cushing's disease of Nelson's syndrome to synthetic ovine corticotropin-releasing factor (CRF), vasopressins, somatostatin-28, dexamethasone, 3-isobutylmethylxanthine or high [K ...

Antidiuretic and pressor activities of vasopressin analogs with L-alaninamide and D-alaninamide substitutions at position 9.

International journal of peptide & protein research, 2009
Analogs of arginine vasopressin (AVP) and lysine vasopressin (LVP)--with an L-alaninamide residue or a D-alaninamide residue replacing the naturally occurring glycinamide in position 9--lose virtually all pressor activity but retain from 10 to 70% of the

Vasopressin and vasopressin antagonists in heart failure and hyponatremia

Current Heart Failure Reports, 2008
Increased synthesis of arginine vasopressin (AVP) plays a critical role in fluid retention and hyponatremia in patients with heart failure. The AVP receptor antagonists constitute a new class of agents that are promising in the management of hyponatremia and congestion.

Phylogeny of neurohypophyseal hormones. Vasopressin polymorphism in three kangaroo species.

International journal of peptide & protein research, 2009
The neurohypophyseal hormones of three species of Australian marsupials belonging to the family Macropodidae (Macropus rufus, Macropus giganteus, Macropus robustus) have been investigated.

Vasopressin

2016
Vasopressins (VPs) are mammalian VP family nonapeptides. VPs are composed of an intramolecular ring structure flanked by two cysteine residues and a C-terminal extension with a basic amino acid residue at position 8. VP causes antidiuresis, blood pressure elevation, stress response, metabolic actions, and various behaviors through three VP receptors. A

Vasopressin stimulation of the isolated adrenal glands: nature and mechanism of hydrocortisone secretion.

Endocrinology, 1960
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. Maximal cortisol

Injection of melatonin into cisterna magna increases concentration of 3', 5' cyclic guanosine monophosphate in cerebrospinal fluid.

Neuroendocrinology, 1976
Rabbits were anesthetized with urethane and were given intracisternal injections of the following substances: adrenocorticotropin, beta-melanocyte stimulating hormone, choroid plexus peptide IIF, epinephrine, serotonin, histamine, oxytocin, lysine and a ...

Vasopressin studies in the rat

Pfl�gers Archiv f�r die Gesamte Physiologie des Menschen und der Tiere, 1968
A modification of Jeffers method for estimating antidiuretic hormone in body fluids is described. With this modification it is possible to detect antidiuretic activity corresponding to 0.25 μU of Vasopressin.
