IGF-I is a critical regulator of uterine growth, and locally produced uterine IGF-I could mediate the effects of 17beta-E2 on growth and cellular proliferation. We used IGF-I knockout (KO) mice and tissue grafting to determine the roles of local and systemic IGF-I in uterine growth and E2 responsiveness. Uteri from adult KO mice and neonatal and adult wild-type (WT) mice were grown under the re...

Reproductive abnormalities cause major losses of sheep production. Abattoir materials were used todetermine the extent of reproductive wastage. Reproductive tracts were collected from 524 ewes slaughtered at Urmia slaughter-house in Urmia, northwest of Iran, during a period of 12 months. Overall, 30.10% of the ewes examined were pregnant. A total of 149 (28.44%) tracts developed acquired reprod...

BACKGROUND AND OBJECTIVES This study was conducted to determine the feasibility and effectiveness of transient occlusion of the uterine arteries (TOUA) during laparoscopic surgery for benign uterine tumors, with preservation of fertility. METHODS Patients with uterine myoma or adenomyoma underwent laparoscopic uterine surgery, with or without TOUA, performed by a single surgeon (Y.-S.K.). Sur...

While the contractile effect of oxytocin on uterine artery has been reported, little is known about whether pregnancy affects the responsiveness of this artery to oxytocin. If it does, is it a consequence of changed endothelial function, as has been proposed for some other vasoconstrictors. Furthermore, the receptor subtypes involved in oxytocin action on uterine artery has not been yet determi...

Introduction: Considering the importance of uterine contractions in uterus retraction and reducing post-partum hemorrhage and the current findings on the effect of the alcoholic extract of pomegranate seed on the uterine contractility, only few studies were made on this issue. In the present study the cumulative effect of the aqueous extract of pomegranate seed on the uterine smooth muscle c...

Objective Antenatal anxiety or maternal stress is a prevalent chronic mental disorder in pregnant women. We assessed the effect of maternal stress because of positive aneuploidy screening results on the alteration of uterine artery’s blood flow. MaterialsAndMethods A prospective cohort (one sample) study as a pilot study was done at a hospital in Tehran. Sixty pregnant women who were candidates...

Uterine tumors are rare in cats, the most common clinical signs observed include presence of abdominal mass, weight loss, anorexia, pain, and vaginal bleeding in some cases. On the other hand, the most commonly diagnosed and thus the most important disease of feline uterus is cystic endometrial hyperplasiapyometra complex (CEH-P). A 12-year-old, sexually intact, female domestic shorthaired cat ...

Uterine sarcoma, a rare solid tumor in uterus, is difficult to identify in the early stage from some benign uterine tumors, such as uterine fibroids. Hence, uterine sarcoma may be treated in the same way as uterine fibroids; and this may not be found until pathological diagnosis. Consequently, this can lead to tumor's abdominal spread, planting and local invasive growth, resulting in an early u...

Background: Uterine rupture can be a catastrophic obstetrical emergency. Many risk factors for uterine rupture have been identified, as well as a wide range of clinical presentations. In this case report, we describe the occurrence of fetal death and uterine rupture in a non-labouring, preterm patient. Case: A 32-year-old woman, gravida 10, para 7, who had three previous lower segment Caesarean...

BACKGROUND Uterine arteriovenous malformation is a rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can be lead to massive hemorrhage. CASE We describe here a case of uterine arteriovenous malformation. A 32-y...
