Central vasopressin signalling and aggressive behaviour
… individual styles of behaviour, are unknown. Vasopressin is the strongest candidate regulator of social behaviour. Experiments were carried out in consideration that vasopressin may directly regulate aggressive behaviour in lactating rats. Patterns of immediate early gene expression …

Structure and function of V1b vasopressin receptor
The V1b vasopressin receptor (V1bR) is a receptor for a neurohypophysial hormone [arginine8] vasopressin (AVP). V1bR is a G-protein coupled receptor (GPCR) belonging to the Family A GPCR superfamily. The structures of seven α-helical transmembrane domains of this family members can be predicted …

Zur Wirkung von Vasopressin beim unkontrollierten hämorrhagischen Schock
… of fluid resuscitation vs. epinephrine vs. vasopressin vs. saline placebo on hemodynamic variables, regional organ blood flow, and short term survival in an animal model of uncontrolled hemorrhagic shock. Twenty-eight anesthetized pigs were subjected to a severe liver injury, which resulted …

A Study of Some Factors Influencing Vasopressin Release
… the presence of increased blood levels of vasopressin in patients suffering cardiac arrest. Experimental evidence has shown that strong emotional stress, hypercapnia and hypoxia are all capable of eliciting an increased blood level of vasopressin (3). With the realization that vasopressin …

The elderly, arginine vasopressin & selective serotonin reuptake inhibitors
… aim was to investigate whether dysregulation of vasopressin function in the elderly using SSRis is a sporadic or usual phenomenon. The null hypothesis is that A VP function is not disturbed by SSRis.

Molecular regulation of vasopressin receptor among (mostly) monogamous prairie voles
… differences are predicted by abundance of the vasopressin receptor 1a (V1aR) in the retrosplenial cortex (RSC), a brain region implicated in spatial memory. We find that variation in RSC-V1aR and associated behaviors are predicted by two alternative avpr1a alleles. These “HI” and “LO” alleles …

The Effects of Lysine Vasopressin on Conditioned Behaviour in Rats
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 significant aspects. Chapter Two reviews behavioural data …

Pressor and depressor aspects of vasopressin in the spontaneously hypertensive rat
… and BP lowering properties of arginine vasopressin (AVP). The hypothesis that endothelin (ET) contributes to the exaggerated pressor responsiveness of the spontaneously hypertensive rat (SHR) to AVP was tested by comparing the changes of BP, cardiac output (CO), and total peripheral …

THE VASOPRESSIN SYSTEM IN DIABETES MELLITUS, OBESITY AND THE METABOLIC SYNDROME
… Animal studies suggest that the arginine vasopressin (AVP) system plays a role in glucose and fat metabolism, but data from humans are limited. Method and results: We analysed plasma copeptin (copeptin), a stable C-terminal fragment of the AVP pro-hormone in the large, Swedish, …

Emergency delivery of Vasopressin from an implantable MEMS rapid drug delivery device
… and validated for the in vivo rapid delivery of vasopressin in a rabbit model. In vitro characterization of device performance found the device capable of reliably and reproducibly delivering 85% of its loaded drug solution. A comparison of intraperitoneal and subcutaneous injections of …

Fluid retention in congestive heart failure-the role of natriuretic peptides and arginine vasopressin
… C-type natriuretic peptide (CNP) and arginine vasopressin (AVP) in CHF is not fully understood. Studies were done in 300days old male normal and cardiomyopathic hamsters with moderate CHF. Their body and heart weights were measured. Blood was collected for ANF measurement. Urine was collected …

Central Cardiovascular Effects of Arginine Vasopressin in the Lateral Habenular Region in Anesthetized Rats
… studies have shown the presence of vasopressinergic and oxytocinergic fibers extending from the paraventricular and suprachiasmatic nuclei in the hypothalamus to other brain structures. The lateral habenular region in the rat brain has been shown to specifically receive …

Vasopressin decreases excitability in rat lateral amygdala neurons through inhibition of hyperpolarization-activated cationic current.
… a primary symptom. The peptide hormones arginine-vasopressin (AVP) and oxytocin (OT) are strongly implicated in social behavior, and may also be involved in the pathophysiology of ASD. Here, we show that AVP causes an increase in excitability, through eliciting a decrease in action potential …

The Role of Arginine Vasopressin Receptor 2 in Microvascular Hyperpermeability During Severe Sepsis and Septic Shock
… strategy for this condition. Arginine vasopressin (AVP), a hypothalamic hormone, has been used exogenously in sepsis to promote vasoconstriction by activating AVP receptor 1 (V1R). However, recent evidence suggests that an increased fluid retention may be associated when AVP receptor 2 …

Investigations into the Actions of Vasopressin Histamine, Isoproterenol, Phentolamine, Phenylephrine, and Propronalol on Flow Through Perfused Rat Livers
… and the adrenergic agonists, histamine, and vasopressin should be tested for antagonism of each other. Dog livers as well as rat livers and healthy as well as cirrhotic livers should be tested because they would provide important data to compare with other research.
