Antidiuretic hormone liberated the vertebrates from their aqueous environment, and permitted them to establish themselves on dry land. The combination of sensitive volume and osmoreceptors, a pituitary secretory apparatus which can vary its output from virtually zero to high levels in a short space of time, and receptor cells functioning in the ...

Vasopressin and Vasopressin Receptor Antagonists [PDF]
Vasopressin, a neurohypophyseal peptide hormone, is the endogenous agonist at V1a, V1b, and V2 receptors. The most important physiological function of vasopressin is the maintenance of water homeostasis through interaction with V2 receptors in the kidney.

Sodium fraction excretion rate in nocturnal enuresis correlates with nocturnal polyuria and osmolality [PDF]
: Purpose: We verify the sodium fraction excretion rate (FE Na) and potassium fraction excretion WE K) rates in monosymptomatic nocturnal enuresis. We also correlate FE Na and FE K to urinary osmolality, nocturnal polyuria and vasopressin in the same ...

The osmoregulation of vasopressin
The concept that secretion of the antidiuretic hormone, arginine vasopressin, is regulated by the osmolality of body water originated with the pioneering studies of Verney over 25 years ago [1]. In a classical series of experiments, this investigator showed that the injection of hypertonic saline into the carotid artery of conscious, hydrated dogs ...

Molecular evolution of the neurohypophysial hormone precursors in mammals: comparative genomics reveals novel mammalian oxytocin and vasopressin analogues [PDF]
Among vertebrates the neurohypophysial hormones show considerable variation. However, in eutherian mammals they have been considered rather conserved, with arginine vasopressin (AVP) and oxytocin (OT) in all species except pig and some relatives, where ...

Background: Laparoscopic cystectomy for ovarian endometrioma, despite its high usefulness, reduces ovarian reserve; so, several methods are proposed to reduce this problem.

Background: We hypothesized that RX246, a vasopressin V1a receptor antagonist, blocks the effect of intranasally administered vasopressin on brain processing of angry Ekman faces.

The Effects of Lysine Vasopressin on Conditioned Behaviour in Rats [PDF]
This thesis is concerned with lysine vasopressin's (LVP's) behavioural activity. Chapter One describes vasopressin's synthesis, secretion, metabolism, pressor, antidiuretic and putative corticotrophic functions with emphasis on behaviourally ...

Control of Renal Tubular Sodium and Water Absorption - An Animated Model
The kidney is among the most complex of internal organs. This is due in large part to the multiple and integrated mechanisms of the kidney and their highly dynamic regulation by a variety of neurohormonal and hemodynamic inputs.
