Physiological effects of arginine vasotocin and mesotocin in cockerels

British Poultry Science, 1988
1. The effects of continuous infusion of 0.1, 1.0 and 10.0 mU/min/kg body weight of arginine vasotocin (AVT) or mesotocin (MT) on cardiovascular and thermoregulatory responses, on plasma osmolality and ionic composition and on plasma concentrations of AVT, MT, prolactin and aldosterone, were investigated in conscious White Leghorn cockerels. 2. Neither

A study of the antigonadotrophic action of synthetic arginine vasotocin

Experientia, 1968
L'arginine vasotocine est capable d'inhiber la reponse de la souris impubere a la stimulation gonadotrope, mais ne semble pas agir directement in vitro sur l'excretion hypophysaire, comme le fait le facteur inhibiteur epiphysaire present dans la poudre totale et dans la fraction F 3, obtenu apres filtration d'un extrait epiphysaire sur gel Sephadex G ...

Central Corticotropin Inhibition by Arginine Vasotocin in the Mouse

Neuroendocrinology, 2008
A single injection of 1 µU synthetic arginine vasotocin (AVT) into the 3rd cerebral ventricle of the mouse on the day of surgery, completely inhibited the compensatory adrenal hypertrophy (CAH) measured 3 days later. Neither arginine vasopressin nor oxytocin, administered under the same conditions, are able to inhibit CAH. Because 1 µU AVT i.v.

Arginine vasotocin and renal function in the conscious dog

Peptides, 1982
The effects of arginine vasotocin (AVT), 4-6 ng/kg, on renal function and plasma prolactin (PRL) were determined in conscious American foxhounds undergoing a water diuresis. Intravenous AVT produced an antidiuresis, kaliuresis and inconsistent natriuresis, independently of changes in GFR, blood pressure, heart rate and plasma PRL.

Administration of Arginine-Vasotocin (AVT) to Human Subjects

1979
Publisher Summary This chapter outlines the study of administration of arginine-vasotocin (AVT) to human subjects. As in mammals, synthetic arginine-vasotocin (AVT) produces marked effects on the secretion of the anterior pituitary and on sleep induction, especially when intraventricularly administered, but also intraperitoneally or intravenously, so

Arginine Vasotocin and a Novel Oxytocin-Vasotocin-Like Material in Plasma of Human Newborns

Biology of the Neonate, 2009
Plasma of human adults contains an oxytocin, vasotocin-like (OT-VT) immunoreactive material that is estrogen responsive in both males and females and the levels of which are elevated during pregnancy. Although OT-VT is immunoreactive with an antiserum raised against synthetic arginine vasotocin (AVT), the elution profile of OT-VT by high-performance ...

Pituitary and plasma arginine vasotocin levels in teleost fish

General and Comparative Endocrinology, 1991
The role of arginine vasotocin (AVT) in teleostean osmoregulation is unclear. Its administration may produce dose-dependent effects on renal fluid loss though the physiological significance of such effects is unknown due to the paucity of data on the normal range in pituitary and plasma AVT levels.

Urinary Clearance of Arginine Vasotocin in Pekin Ducks

General and Comparative Endocrinology, 1995
To quantify the renal excretion of arginine vasotocin (AVT) in birds, synthetic AVT was infused into conscious Pekin ducks at rates of 0.03, 0.10, and 0.30 ng/kg/min for 30 min and the relationships between plasma and urine AVT concentrations were monitored by radioimmunoassay.

The Cardiovascular and Renal Effects of Hydrins and Arginine Vasotocin in Frogs

General and Comparative Endocrinology, 1993
Cardiovascular and renal actions of hydrins and arginine vasotocin (AVT) in frogs (Rana tigrina and Rana catesbeiana) were examined in view of their relationships as precursor/prohormone-hormones in the anuran amphibian. In vitro hydrins and AVT respectively vasorelaxed and vasoconstricted KCl-preconstricted femoral artery in R. tigrina.

Vascular effects of arginine vasotocin in toad skin

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1993
Fluid balance in amphibians is regulated, in large part, by arginine vasotocin (AVT). One important action of this hormone is to facilitate water uptake by increasing the water permeability of the skin. Cutaneous blood flow also affects water uptake, but the effects of AVT on skin perfusion are unknown.
