Uterine contractions play a very important role in the smooth delivery process. However, some mothers experience problems uterine which will result length of labor So cases need induction assistance. Advances medical science terms acupressure and rebozzo have become several solutions for certain treatments without involving chemistry it. This study aims to be applied directly this case help red...

During the final hours of pregnancy, uterine contractions cause the foetus to move through the birth canal and leave the mother's body. Haly Abbas (died 982-994 CE), is believed to be the first writer to explain the role of these contractions. However, this concept had in fact been described in the text titled Bab-e-Borzouyeh, written four centuries earlier by the physician Borzouyeh (Perzoes i...

OBJECTIVE Oxytocin is frequently used by intravenous bolus and infusion to minimize blood loss and prevent postpartum hemorrhage at cesarean delivery. Current dosing regimens are arbitrary whereas large doses may pose a serious risk to the mother. The purpose of this study was to estimate the minimum effective intravenous bolus dose of oxytocin (ED90) required for adequate uterine contraction a...

This study was designed to assess the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. One hundred twenty-three nulliparas with a singleton cephalic pregnancy at term were randomized. Standard care was performed in the control group, and uterine fundal pressure by the Labor Assister (Baidy M-420/Curexo, Inc., Seoul, Korea) was utili...

Objective: Nymphaea alba is a medicinal plant used in tropical regions for its genital, gastrointestinal and bronchial activities. In the present study, the probable effect of the ethanol extract of the rhizome on rat uterus in the presence of standard antagonists like salbutamol and atropine and a uterine stimulant like oxytocin were examined. Methods: This work examined the effect of the etha...

Plasma pH can be altered during pregnancy and at labor. Membrane excitability of smooth muscle including uterine muscle is suppressed by the activation of K(+) channels. Because contractility of uterine muscle is regulated by extracellular pH and humoral factors, K(+) conductance could be connected to factors regulating uterine contractility during pregnancy. Here, we showed that TASK-2 inhibit...

Vaginal ultrasonography of uterine peristalsis during the follicular phase of the menstrual cycle demonstrates an increasing frequency and intensity of subendometrial and myometrial peristaltic waves as the follicular phase progresses. During this time the numbers of contraction waves with a fundo-cervical direction decrease considerably in favour of waves of contraction with a cervico-fundal d...

The importance of gaining insight into the mechanisms underlying uterine quiescence and contractility is highlighted by the absence of an effective strategy to prevent or treat preterm labor, the greatest cause of perinatal mortality and morbidity worldwide. Although current evidence suggests that in myometrial smooth muscle cells (mSMCs) calcium homeostasis is modulated near term to promote ut...

OBJECTIVE Erythromycin stimulates stomach smooth muscle contraction via action on motilin receptors, but the effects of erythromycin on non-pregnant uterine smooth muscle are unknown. The purpose of this study was to assess the effect of erythromycin on non-pregnant uterine smooth muscle and to examine the possible mechanism of its action. STUDY DESIGN Uterine smooth muscle strips from rats w...
