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.

Serious Adverse Events Associated With Vasopressin and Norepinephrine Infusion in Septic Shock*

Critical Care Medicine, 2014
Objective:The frequency, risk factors, and mortality rates of serious adverse events associated with the use of vasopressin and norepinephrine are not clear. The objectives of this study were to determine frequency, risk factors (including candidate gene

Renal microvascular effects of vasopressin and vasopressin antagonists

American Journal of Physiology-Renal Physiology, 1989
The effects of vasopressin (AVP) and vasopressin antagonists on lumen diameters of cortical afferent and efferent arterioles isolated from rabbit kidneys were examined. Over a concentration range of 10(-14) to 10(-7) M, AVP had no effect on lumen diameters of afferent arterioles, although the arterioles were responsive to norepinephrine.

Vasopressin and Vasopressin Receptor Antagonists in Heart Failure

Cardiology in Review, 2009
Antidiuretic hormone, also known as arginine vasopressin, is a hormone with a multitude of physiologic activities including the control of urinary free water excretion. Antidiuretic hormone also plays a role in vasoconstriction and has 3 receptors that have been identified.

Vasopressin and Oxytocin Excite Distinct Neuronal Populations in the Central Amygdala

Science, 2005
Vasopressin and oxytocin strongly modulate autonomic fear responses, through mechanisms that are still unclear. We describe how these neuropeptides excite distinct neuronal populations in the central amygdala, which provides the major output of the ...

Oxytocin and vasopressin

Neurology, 2013
Oxytocin (OXT) and arginine vasopressin (AVP) are 2 closely related neuropeptides, widely known for their peripheral hormonal effects. However, OXT, AVP, and their receptors are also expressed in several areas of the CNS and exert widespread ...

Vasopressin metabolites: A link between vasopressin and memory?

1999
The effects of endogenous metabolites of the neuropeptide vasopressin (VP) in behavioural tests led to the hypothesis that VP metabolites have a more selective function than VP. In contrast to VP, no peripheral effects have been found thus far with VP metabolites and their function seems to be associated with memory-related behaviour.

Vasopressin in Cardiovascular Control: Role of Circulating Vasopressin

Clinical Science, 1984
Vasopressin has been shown to elicit vasoconstriction in unanaesthetized animals at plasma concentrations similar to those associated with its renal antidiuretic effect. The vasconstrictor effects of vasopressin do not normally translate into pressor responses until relatively high plasma concentrations are reached.

Mechanisms of Vasopressin Secretion

Hormone Research, 1992
The magnocellular vasopressin system of the rat has been studied intensively in recent years. This review outlines the electrophysiological characteristics of vasopressin neurons, the characteristics of stimulus-secretion coupling in the neural lobe, and describes some of the major features of the neural regulation of this system which underlie ...
