Arginine vasotocin and aggression in rats

Peptides, 1984
Pinealectomized (PX) and sham animals were administered either AVT (1 ng/kg) or vehicle (1 ml H20). Boxing-kicking-biting episodes were significantly reduced by administration of AVT, F(1,21) = 8.09, p less than 0.009. Crawling under behavior was increased in PXH20 animals (p less than 0.05).

Arginine vasotocin and fish osmoregulation

Fish Physiology and Biochemistry, 1993
Pituitary arginine vasotocin (AVT) secretion is sensitive to the osmotic challenge associated with transfer of euryhaline teleosts between sea water (SW) and fresh water (FW). Pituitary AVT content in FW-adapted flounders greatly exceeds that in SW-adapted fish. Plasma AVT concentrations are in the range 10(-12)-10(-11) M (1-100 pg/ml).

Antipyretic effect of arginine vasotocin in toads

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2000
Arginine vasotocin (AVT) is a nonmammalian analog of the mammalian hormone arginine vasopressin (AVP). These peptides are known for their antidiuretic and pressor effects. More recently, AVP has been recognized as an important antipyretic molecule in mammals. However, no information exists about the role of AVT in febrile ectotherms.

Arginine Vasotocin in the Rabbit Subcommissural Organ

Endocrinology, 1975
Subcommissural organs of young and mature rabbits were analyzed for their content of arginine vasotocin by radioimmunoassay. Younger animals had significantly greater quantities of this peptide. There was no detectable arginine vasopressin or oxytocin in subcommissural organ extracts.

The cardiac effects of arginine vasotocin in amphibians

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1988
1. The cardiac effects of arginine vasotocin (AVT) on isolated atria were examined in three anuran and one urodele species. 2. AVT produced dose-related positive chronotropic and inotropic responses. 3. The responsiveness of the atrial tissue varied among species. 4.

The natriuretic action of [4-Leucine]-arginine-vasotocin

Experientia, 1973
[Leu4]-Arginin-vasotocin wirkt so wohl an Katzen (Chloralose-Narkose, Mannit-Diurese) als auch an wachen Ratten (mit 0.9%-iger NACl-Losung belastet) und wachen nicht vorbehandelten Hunden natriuretisch und diuretisch.

Arginine Vasotocin: Effects on Development of Reproductive Organs

Science, 1974
Immature 25-day-old mice were injected daily with 1 microgram of arginine vasotocin for 3 or 4 days and killed 24 hours after the last injection. The ovaries were 30 percent smaller in treated females than in controls. The ventral prostates and accessory organs (seminal vesicles and coagulating glands) were less than half the size of these structures ...

Prolactin-Releasing Activity of Arginine Vasotocin in vitro

Hormone Research, 2008
A significant elevation in both luteinizing hormone (LH) and prolactin release was observed in the culture medium of hemipituitaries from castrated estrogen-progesterone (EP) primed female rats incubated for 5 h with arginine vasotocin (AVT) and luteinizing hormone-releasing hormone (LRH) compared to corresponding halves incubated with LRH alone ...

Regulation of the avian kidney by arginine vasotocin

General and Comparative Endocrinology, 2006
Nonapeptides secreted by the neurohypophysis have important roles in vertebrate cardio-fluid homeostasis. In birds, those peptides include mesotocin (the representative of the neutral, or oxytocin-like, nonapeptide family) and vasotocin (the representative of the basic, or vasopressin-like, hormones).
