vasopressin

 [vas″o-pres´in]
a hormone secreted by cells of the hypothalamic nuclei and stored in the posterior pituitary for release as necessary; it stimulates contraction of the muscular tissues of the capillaries and arterioles, raising the blood pressure, and increases peristalsis, exerts some influence on the uterus, and influences resorption of water by the kidney tubules, resulting in concentration of urine. Its rate of secretion is regulated chiefly by the osmolarity of the plasma. Also prepared synthetically or obtained from the posterior pituitary of domestic animals; used as an antidiuretic. Called also antidiuretic hormone.
Vasopressin (ADH) regulation. ADH is secreted by the posterior pituitary gland primarily in response to an increase in plasma osmolality. From Malarkey and McMorrow, 2000.
arginine vasopressin vasopressin containing arginine, as that from humans and most other mammals; for medicinal uses, see vasopressin. Called also argipressin.
lysine vasopressin the antidiuretic hormone of the pig family, differing from arginine vasopressin in having lysine instead of arginine at position 8. A synthetic preparation, lypressin, is used as an antidiuretic and vasoconstrictor.

ar·gi·nine va·so·pres·sin (AVP),

[MIM*192340]
vasopressin containing an arginyl residue in position 8 (as in chickens and most mammals, including humans); porcine vasopressin has a lysyl residue at position 8. All are vasopressors.
Synonym(s): argipressin

arginine vasopressin

vasopressin containing arginine, as that from humans and most other mammals; for medicinal uses. Also called argipressin.

arginine vasopressin

ADH-antidiuretic hormone, see there.

ar·gi·nine va·so·pres·sin

(AVP) (ahr'ji-nēn vā'sō-pres'in)
This agent contains an arginyl residue in position 8 (as in chickens and most mammals, including humans); porcine vasopressin has a lysyl residue at position 8. All are vasopressors.

arginine vasopressin

VASOPRESSIN, one of the two hormones from the rear lobe of the PITUITARY GLAND. The antidiuretic hormone in humans.

arginine

a basic amino acid occurring in proteins and essential for many species, particularly the cat.

arginine amidinase
arginine deaminase test
see arginine dihydrolase test (below).
arginine dihydrolase test
a test for the identification of bacteria, based on the conversion of l-arginine to putrescine. In a positive result, the alkaline product is indicated by bromocresol purple. Called also arginine deaminase test.
arginine esterase
an androgen-dependent enzyme derived from the prostate which occurs in high concentrations in seminal plasma.
arginine nutritional deficiency
results in elevated blood ammonia concentration. Cats are particularly sensitive and within hours of eating an arginine-free diet, severe neurological signs develop, leading to death. In other species, cataracts have been reported in dogs and feather abnormalities occur in chickens on deficient diets.
arginine vasopressin
a potent vasoconstrictor in mammals.
arginine vasotocin
the normal antidiuretic hormone in birds; released from the avian posterior pituitary.
