BACKGROUND Recent interest in the social and cognitive effects of intranasal oxytocin prompts a need for understanding its physiological effects in humans. Few studies have examined the effects of intranasal oxytocin on steroid hormones. Filling this gap is especially important given the evidence that steroid hormones participate in some of the same behavioral functions as oxytocin, e.g. in str...
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...
The neuropeptide, oxytocin, receives increasing attention due to its role in stress regulation and promoting affiliative social behavior. Research across mammals points to a complex pattern whereby social context and individual differences moderate the central release of oxytocin as well as moderate the effects that exogenous administration of oxytocin has on social behavior. In addition, it is...
BACKGROUND Oxytocin, a neurohypophyseal neuropeptide, is a potential mediator and regulator of drug addiction. However, the cellular mechanisms of oxytocin in drug seeking remain unknown. METHODS In the present study, we used a self-administration/reinstatement model to study the effects of oxytocin on cocaine seeking and its potential interaction with glutamate function at the receptor level...
We have previously shown that oxytocin receptors are present in the heart and that perfusion of isolated rat hearts with oxytocin results in decreased cardiac flow rate and bradycardia. The mechanisms involved in the negative inotropic and chronotropic effects of oxytocin were investigated in isolated dog right atria in the absence of central mechanisms. Perfusion of atria through the sinus nod...
BACKGROUND During pregnancy asthma may remain stable, improve or worsen. The factors underlying the deleterious effect of pregnancy on asthma remain unknown. Oxytocin is a neurohypophyseal protein that regulates a number of central and peripheral responses such as uterine contractions and milk ejection. Additional evidence suggests that oxytocin regulates inflammatory processes in other tissues...
The hypothalamic neuropeptide oxytocin attracts the attention of both the neuroscientific community and the general public, especially because of its prosocial effects. In the brain, this neuropeptide is synthesized in neurons exclusively located within the hypothalamic nuclei. Magnocellular neurons compose the larger population of oxytocinergic neurons, project to the posterior pituitary lobe ...
Background: Postpartum hemorrhage considered to be one of the most important cause of women mortality in developing countries. Usage of oxytocin is one of the outstanding success in medicine but it should not be taken for granted and should be used only if it is necessary and not as routine. Objective: To determine the amount of postpartum hemorrhage on the absence of IM injection of oxyt...
Background and purpose: Since bleeding due to the prolongation of the third stage of labor is one of the most common cause of mortality in the developing countries, we decided to conduct a comparative study on the effect of oxytocin and normal saline injected into umbilical vein on the shortening of the third stage of labor. Ïn referrees to Ïmam Khomeini delivery center of Sari in 1375. Ma...
Objectives: The aims of the present study were to compare the efficacy of oxytocin bolus alone, oxytocin bolus and infusion, carbetocin bolus alone, and carbetocin bolus followed by oxytocin infusion in reducing blood loss during and after cesarean section and reducing the needs for additional uterotonic agents. Methods: 200 women scheduled for elective CS under spinal anaesthesia were divided ...
