Adenomyosis is a common gynecological disorder characterized by the presence of endometrial glands and stroma deep within the myometrium associated with myometrial hypertrophy and hyperplasia. Focal uterine infarction after IVF-ET in a patient with adenomyosis following biochemical pregnancy has not been previously reported, although it occurs after uterine artery embolization in order to control symptoms caused by fibroids or adenomyosis. We report a case of a nulliparous woman who had uterine adenomyosis presenting with fever, pelvic pain and biochemical abortion after undergoing an IVF-ET procedure and the detection of a slightly elevated serum hCG. Focal uterine infarction was suspected after a pelvic magnetic resonance imaging demonstrated preserved myometrium between the endometrial cavity and inner margin of the necrotic myometrium. This case demonstrates that focal uterine infarction should be considered in the differential diagnosis of acute abdominal pain, vaginal bleeding and infectious signs in women experiencing biochemical abortion after an IVF-ET procedure.

Purpose : The objective of this study is to serve guidelines for the investigation and management of uterine myomas with KM therapies. Methods : English-language articles from PubMed and Korean-language articles from the database of the journal of oriental gynecology were reviewed from 2000 to 2005, using the key words 'uterine myoma', 'uterine leiomyoma', 'fibroid', 'uterine artery embolization', 'endometrial ablation', 'myomectomy', and jagungguenjong(子宮筋腫)'. Results and Limits : The areas of clinical practices considered in formulating this guideline are assessment, KM therapies, medical treatments, myolysis, selective artery occlusion, endometrial ablation and surgical therapies including myomectomy and hysterectomy. Implementation of this guideline would optimize the decision-making process of women with uterine myomas and further investigation or therapy of their KM doctors. But we don't have abundant evidences of clinical trials of uterine myoma treated with KM therapy, though we treat or manage that with every-day clinical practices. Moreover cultural gaps between Korea and other western countries make many differences in the attitude to surgical therapies, especially hysterectomy. So it is very difficult to compare W therapies with other therapies. Moreover it is much difficult to estimate cost-effectiveness and benefit of those therapies in QOL. Conclusions : The majority of uterine myoma is asymptomatic and will not require any intervention or further investigation. But unmarried women who wish to marry and get pregnant want to find safe therapy for their asymptomatic uterine myomas. In that case, most of the patients prefer non-surgical therapy to surgical therapy. So KM herbal medicinal therapy is a good alternative method for those patients. For the symptomatic myomas, hysterectomy offers a definitive solution. However, it is not the best solution for women who wish to preserve their uterus. So KM therapy is a good alternative for them. But the predicted benefits of alternative therapies including KM therapy must be carefully weighed against the Possible risks of these therapies. To improve the quality of life of both women with asymptomatic and symptomatic myomas, selecting and treating patients should be done carefully. Moreover, the effect of KM therapy has to evaluated, comparing the possible situation without treatment and the benefit of constant treatment as a health-care system.

The plasma levels of 23 free amino acids in both the umbilical circulation (umbilical vein and artery) and the maternal circulation (antecubital vein, uterine vein and iliac artery ) of 34 pregnant women were measured at delivery by the cesarean section. Each amino acid with the exception of glutamate was found to be in higher concentration in the fetal blood and the cord plasma characterized by hyperaminoacidemia with a marked increase of the lysine and ornithine levels. The linear relationships found between the amino acids concentrations of iliac artery and those of umbilical vein suggest three transport groups across the placental membrane One group consists of neutral amino acids whose slopes are equal to one and the other two groups are characterized by their slopes higher and lower than unity respectivly. This division into three groups is tentatively explained by the result of a dynamic equilibrium between active transport towards the fetus and diffusion back towards the maternal circulation.

The inferior mesenteric artery is a rare source of postpartum hemorrhage. We report two cases of primary postpartum hemorrhage that originated from the inferior mesenteric artery after vaginal delivery. Both patients showed signs of hypovolemic shock, and disseminated intravascular coagulation was suspected. The bleeding continued even after embolization of the uterine artery, a typical source of postpartum hemorrhage. Inferior mesenteric arteriography confirmed contrast extravasation from the superior rectal artery, and selective embolization was performed using N-butyl cyanoacrylate. This report highlights that the inferior mesenteric artery can be a source of bleeding in patients with intractable and persistent postpartum hemorrhage due to birth canal injury.

Endometriosis-related symptoms are believed to be alleviated during pregnancy. However, pregnancy complications, such as pseudoaneurysm of the uterine artery, rupture of ovarian or uterine vessels, and intraabdominal bleeding from decidualized deep infiltrating endometriosis (DIE) lesion have been rarely reported. Owing to the potential risk of rupture and resultant life-threatening complications, proper diagnosis and close monitoring of decidualized endometriotic lesion are very important despite its low relative risk. Till date, massive vaginal bleeding from decidualized rectovaginal DIE during pregnancy has not been in English literatures. Here, we present the first case of spontaneous massive vaginal bleeding due to decidualized rectovaginal DIE that occurred in the late third trimester of pregnancy.

Objective: This study was aimed to investigate whether uterine blood flow on the day of embryo transfer can be a predictor of pregnancy outcome in human IVF. Methods: Fifty-one patients undergoing IVF program were included in this study. Serum estradiol levels were measured on the day of hCG administration and uterine pulsatility index (PI) and resistance index (RI) was examined for at embryo transfer of day 3. Results: Of 51 cycles, 22 cycles were clinically pregnant (43.1%) and the implantation rate was 14.7%. Uterine PI and RI had a significant inverse correlation with serum estradiol levels (p<0.05). These uterine blood flows were not significantly different between pregnant and nonpregnant groups. The pregnancy rate was slightly higher in patients with PI more than 3.0 compared to those with PI of 3.0 or less, but there was no significant difference. Conclusion: These results suggest that uterine PI and RI at the day of embryo transfer could not be a good predictor of pregnancy in IVF treatment. But they had an inverse correlation with serum estradiol levels on the day of hCG administration.

Background: The research was to compare the efficacy and side effects of cisplatin or lobaplatin in combination with mitomycine (MMC) and vincristine in treating patients with cervical squamous carcinoma. Materials and Methods: Cervical squamous carcinoma patients who were pathologically diagnosed with stage Ib-IIb from April 2012 to May 2013 in the general hospital of Chinese People's Libration Amy were enrolled. All patients were confirmed without prior treatment and were randomly divided into two groups, Group A and B. Efficacy and side effects were evaluated after one cycle of chemotherapy. Results: Group A (n=42) were treated with Loubo$^{(R)}$ (Lobaplatin) $50mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. Group B (n=44) were treated with Cisplatin $100mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. All 86 patients completed one cycle of chemotherapy with cisplatin or lobaplatin in combination with MMC and vincristine. No difference was observed regardiing short-term effect between two groups. Main side effects were bone marrow suppression and gastrointestinal reactions including decrease of white blood cells, platelet and nausea/vomiting. Grade III-VI liver and kidney impairment was not reported in two groups. In group A the incidence of uterine artery spasm in the process of drug delivery was significantly lower than the group B. Conclusions: Cisplatin or lobaplatin with MMC and Vincristine in the interventional treatment of cervical squamous carcinoma were effective, especially after uterine artery perfusion chemotherapy at tumor reduction and tumor downstaging period. The adverse reactions of concurrent chemotherapy are tolerable, and low physical and mental pressure even more less stimulation of vascular in treatment with lobaplatin. However, the long-term effects of this treatment need further observation.

Purpose This study aimed to evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for bleeding due to uterine body cancer. Materials and Methods In this retrospective study, six patients with varying types of uterine body cancer who underwent TAE for bleeding control were investigated. Angiographic findings, cross-sectional images, TAE details, and clinical outcomes were studied. Technical and clinical success rates were calculated. Results The identified patients had endometrioid adenocarcinoma, sarcoma, and gestational trophoblastic neoplasia, and most were patients with advanced-stage cancer. In four patients, tumor bleeding presented as vaginal bleeding. Technical success was achieved in all seven TAE procedures in six patients. Two patients with recurrent masses who had undergone hysterectomy presented with hematochezia, and TAE was able to provide technical success in these patients as well. The clinical success rate was 50%, indicating bleeding control for > 1 week. Rebleeding was directly associated with death in one patient. On the following day, mild fever was observed in one patient. Conclusion TAE can be considered an effective and safe method of bleeding control for uterine body cancer, especially during critical periods throughout the disease course of patients with inoperable, advanced-stage cancer.

Objective : The purpose of this study was to investigate the prenatal hypoxic effect on the fetal brain development. Methods : We used the guinea pig chronic placental insufficiency model to investigate the effect of hypoxia on fetal brain development. We ligated unilateral uterine artery at 30-32 days of gestation (dg : with term defined as -67 dg). At 50 dg, 60 dg, fetuses were sacrificed and assigned to either the growth-restricted (GR) or control (no ligation) group. After fixation, dissection, and sectioning of cerebral tissue from these animals, immunohistochemistry was performed with NeuN antibody, which is a mature neuronal marker in the cerebral cortex. Results : The number of NeuN-immunoreactive (IR) cells in the cerebral cortex did not differ between the GR and control groups at 50 dg. However, the number of NeuN-IR cells was lesser in GR fetuses than in controls at 60 dg (p<0.05). Conclusion : These findings show that chronic prenatal hypoxia affect the number of neuron in the cerebral cortex of guinea pig fetus at 60 dg. The approach used in this study is helpful for extending our understanding of neurogenesis in the cerebral cortex, and the findings may be useful for elucidating the brain injury caused by prenatal hypoxia.

Invasion of trophoblasts into maternal uterine tissue is essential for establishing mature feto-maternal circulation. The trophoblast invasion associated with placentation is similar to tumor invasion. In this study, we investigated the role of KAI1, an anti-metastasis factor, at the maternal-fetal interface during placentation. Mouse embryos were obtained from gestational days 5.5 (E5.5) to E13.5. Immunohistochemical analysis revealed that KAI1 was expressed on decidual cells around the track made when a fertilized ovum invaded the endometrium, at days E5.5 and E7.5, and on trophoblast giant cells, along the central maternal artery of the placenta at E9.5. KAI1 in trophoblast giant cells was increased at E11.5, and then decreased at E13.5. Furthermore, KAI1 was upregulated during the forskolin-mediated trophoblastic differentiation of BeWo cells. Collectively, these results indicate that KAI1 is differentially expressed in decidual cells and trophoblasts at the maternal-fetal interface, suggesting that KAI1 prevents trophoblast invasion during placentation.
