The change in the amount of immunoreactive oxytocin in human term placental tissue due to cycloheximide, an inhibitory agent of protein biosynthesis, was observed by a tissue culture method. The immunoreactive oxytocin content per gram tissue was 1.81 ng/g and significantly decreased to 1.17-1.11 ng/g when the concentrations of cycloheximide were at 1-10 micrograms/ml in culture medium. The tot...

BACKGROUND AND AIM Social factors may be of importance causally and act as maintenance factors in patients with anorexia nervosa. Oxytocin is a neuromodulatory hormone involved in social emotional processing associated with attentional processes. This study aimed to examine the impact of oxytocin on attentional processes to social faces representing anger, disgust, and happiness in patients wit...

OBJECTIVE to evaluate the effects of labor stimulation with oxytocin on maternal and neonatal outcomes. METHOD descriptive and analytical study with 338 women who gave birth at a tertiary hospital. Obstetric and neonatal variables were measured and compared in women submitted and non-submitted to stimulation with oxytocin. Statistics were performed using Chi-square test, Fisher exact test, St...

BACKGROUND Oxytocin is known for its capacity to facilitate social bonding, reduce anxiety and for its actions on the stress hypothalamopituitary adrenal (HPA) axis. Since oxytocin can physiologically suppress activity of the HPA axis, clinical applications of this neuropeptide have been proposed in conditions where the function of the HPA axis is dysregulated. One such condition is major depre...

OBJECTIVE The neuropeptide oxytocin is implicated in social processing, and recent research has begun to explore how gender relates to the reported effects. This study examined the effects of oxytocin on social affective perception and learning. METHODS Forty-seven male and female participants made judgments of faces during two different tasks, after being randomized to either double-blinded ...

Postpartum hemorrhage is an important cause of maternal morbidity and mortality after delivery. Active management of postpartum hemorrhage by an uterotonic drug decreases the rate of postpartum hemorrhage. The aim of this study is to evaluate the efficacy of rectal misoprostol for prevention of postpartum hemorrhage. This double blind randomized clinical trial was performed on full term pregnan...

a quasi experimental study was conducted in the labour rooms of one of the hospital's of the university of   medical science of iran, to compare the effect ofcord blood drainage and oxytocin injection into the umblicat   vein in the duration of the third stage of labour.   a total of 180 women in the course of normal pregnancies with no complications and normal vaginal   dd ivery were sele...

BACKGROUND Social recognition underlies social behavior in animals, and patients with psychiatric disorders associated with social deficits show abnormalities in social recognition. Oxytocin is implicated in social behavior and has received attention as an effective treatment for sociobehavioral deficits. Secretin receptor-deficient mice show deficits in social behavior. The relationship betwee...

BACKGROUND As the interval between rupture of the fetal membranes at term and delivery increases, so may the risk of fetal and maternal infection. It is not known whether inducing labor will reduce this risk or whether one method of induction is better then another. METHODS We studied 5041 women with prelabor rupture of the membranes at term. The women were randomly assigned to induction of l...

In recent years more and more studies have revealed the effect of extraneous oxytocin on the social behavior of dogs. The distribution of administered oxytocin in different physiologically relevant compartments is important because this knowledge forms the basis for the timing of behavior tests after the administration. Most behavioral studies rely on the non-invasive intranasal application of ...
