American Journal of Obstetrics and Gynecology, 1967
Abstract An antibody to oxytocin has been developed. It has been shown to be specific, and a reproducible immunologic method of quantitation has been illustrated. The biologic activity of this small hormone appears to have been inhibited by antibody, and localization of this octapeptide in tissue has been demonstrated by immunofluorescence.

Journal of Endocrinology, 1978
Abstract The evaluation of a radioimmunoassay of oxytocin is described. The method involved careful collection and transportation of blood at 4 °C, acidification of the plasma, extraction with Fuller's earth and radioimmunoassay using antisera raised in rabbits immunized against oxytocin conjugated to bovine serum albumin and 125I ...

The oxytocin receptor was first identified using a pharmacological ligandbinding assay in the rat myometrium (Soloff and Swartz 1973). Its peptide ligand, oxytocin, belongs to the nonapeptide hormone family comprising both oxytocin-like (mesotocin, isotocin, etc.) and vasopressin-like (vasotocin, phenypressin, etc.) cyclic peptides.

Determination of oxytocin in milk of cows administered oxytocin
Analytica Chimica Acta, 2009To address people's concerns of exogenous oxytocin (OT) administration to lactating bovines, a study was undertaken to (a) establish an enzyme immunoassay (EIA) for OT determination in milk, (b) quantify OT in milk of cows administered OT, and (c) study influence of pasteurization on OT stability in milk.

Social signals are identified through processing in sensory systems to trigger appropriate behavioral responses. Social signals are received primarily in most mammals through the olfactory system. Individuals are recognized based on their unique blend of odorants.

Testicular oxytocin: effects of intratesticular oxytocin in the rat
Journal of Endocrinology, 1991ABSTRACT The long-term effects of oxytocin administration on the testis were studied using intratesticular implants. Adult male rats had an Accurel device containing 20 μg oxytocin (releasing approximately 200 ng/day) implanted into the parenchyma of each testis; control animals received empty devices.

Regulation of Oxytocin Receptors and Oxytocin Receptor Signaling
Seminars in Reproductive Medicine, 2007The oxytocin (OT) -oxytocin receptor (OTR) system plays a key role in many aspects of mammalian reproduction as well as several other physiological processes such as bond pairing and cardiovascular homeostasis. To manifest these diverse physiological roles, the transcription and expression of the OTR is tightly regulated within reproductive ...

Oxytocin has potent central effects on feeding behaviour, as well as on social and sexual behaviours, and one likely substrate for its anorectic effect is the ventromedial nucleus of the hypothalamus. This nucleus expresses a high density of oxytocin receptors, but contains very few oxytocin-containing fibres, hence it is a likely target of ...

Loss of myometrial oxytocin receptors during oxytocin-induced and oxytocin-augmented labour
Reproduction, 2000Abstract Oxytocin is used widely for the induction and augmentation of labour, but there is little information about the dynamics of oxytocin receptors in human myometrium during parturition, and the possible effect of oxytocin infusion.

Oxytocin and Oxytocin Receptor Gene Expression in the Uterus
1995Publisher Summary The posterior pituitary contains a strong uterotonic activity known as the nonapeptide oxytocin (OT). It has been determined that uterus itself represents a major site of OT production. Therefore, the activation of uterine contractions by circulating OT is only one aspect of OT action. A significant portion of OT activity originates
