OBJECTIVE In this paper we present our observation of a specific sign on transvaginal ultrasound that may help basic minimal invasive surgeons diagnose vesico-uterine adhesions preoperatively. METHODS The ultrasound images of the latest eleven patients who were preoperatively diagnosed with vesico-uterine adhesions using transvaginal ultrasound were compared with their intraoperative findings...

Whole boar semen or seminal plasma has been demonstrated to advance the time of ovulation in gilts. As a means of clarifying this influence, the contribution of uterine lymphatics and their white cell populations has been examined. After duct visualisation with Evan's blue, lymph was sampled from a mesometrial vessel in eight pre-ovulatory gilts whose uterine lumen was infused simultaneously wi...

Background: Approximately 3% to 5% of obstetric patients will experience postpartum hemorrhage (PPH). Even though the most common reason for postpartum hemorrhage, as the main cause of maternal death, is uterine atony; other complications such as laceration, hematoma, inversion, rupture; retained tissue or invasive placenta; and coagulopathy may result in PPH. The main cause of retained placent...

Primary dysmenorrhea (PD) is a common gynecological disorder. Hitherto, animal models which recapitulate clinical features of PD have not been fully established. We aimed to examine whether a pain model in mice could mimic the clinic features of PD. After pretreated with estradiol benzoate (1 mg/kg/day) intraperitoneally (i.p.) for 3 consecutive days, non-pregnant female Imprinting Control Regi...

The uterus plays a central role among the reproductive tissues in the context of early embryo-maternal communication and a successful pregnancy depends on a complex series of endometrial molecular and cellular events. The factors responsible for the initial interaction between maternal and embryonic tissues, leading to the establishment of pregnancy, remain poorly understood. In this context, I...

The relative contribution of systemic versus local (intrauterine) factors in the activation and stimulation of the sheep myometrium during labour was examined using an in-vivo myometrial explant preparation. Myometrial tissue alone (MYO) or with attached endometrium (ENDO/MYO) was removed from the pregnant uterine horn, sutured to a stainless-steel frame and placed into the omental fat. After 7...

A rapid method is described for the isolation of Bacillus abortus from the peritoneal cavity of the guinea pig following the injection of uterine exudate or placental tissue.

Somatic cell nuclear transfer (SCNT) is a useful tool for animal cloning, but the efficiency of producing viable offspring by SCNT is very low. To improve this efficiency in the production of cloned pigs, it is critical to understand the interactions between uterine function and cloned embryos during implantation. Lysophosphatidic acid (LPA) is a lipid mediator that plays an important role in t...
