		                        			Trichomonas vaginalis induces proinflammation in cervicovaginal mucosal epithelium. To investigate the signaling pathways in TNF-alpha production in cervical mucosal epithelium after T. vaginalis infection, the phosphorylation of PI3K/AKT and MAPK pathways were evaluated in T. vaginalis-infected SiHa cells in the presence and absence of specific inhibitors. T. vaginalis increased TNF-alpha production in SiHa cells, in a parasite burden-dependent and incubation time-dependent manner. In T. vaginalis-infected SiHa cells, AKT, ERK1/2, p38 MAPK, and JNK were phosphorylated from 1 hr after infection; however, the phosphorylation patterns were different from each other. After pretreatment with inhibitors of the PI3K/AKT and MAPK pathways, TNF-alpha production was significantly decreased compared to the control; however, TNF-alpha reduction patterns were different depending on the type of PI3K/MAPK inhibitors. TNF-alpha production was reduced in a dose-dependent manner by treatment with wortmannin and PD98059, whereas it was increased by SP600125. These data suggested that PI3K/AKT and MAPK signaling pathways are important in regulation of TNF-alpha production in cervical mucosal epithelial SiHa cells. However, activation patterns of each pathway were different from the types of PI3K/MAPK pathways.

		                        			OBJECTIVE: To detect meconium peritonitis for the fetal period is important for prenatal counseling. The aim of this study was to evaluate prenatal ultrasound finding for diagnosing meconium peritonitis and postnatal clinical course and outcomes. METHODS: The prenatal and postnatal medical records of all patients to our institutions with confirmed meconium peritonitis were reviewed, with emphasis on prenatal ultrasound findings, postnatal investigations, operative findings, outcomes of meconium peritonitis. RESULTS: Fourteen fetuses were confirmed to have meconium peritonitis at birth by operation. Eight cases were diagnosed correctly because of prenatal ultrasound showing ascites and calcification/dilated or hyperechoic bowel loops. In the other 6 cases, prenatal ultrasound showed only ascites. One patient was operated on first day of life and its intra-operative finding was malrotation of small bowel, volvulus with strangulation, perforation and jejunal atresia. Most cases were operated on 2nd or 3rd day of life. Intra-operative findings were ileal atresia and perforation in 11 cases and jejunal atresia and perforation in 3 cases. Four patients underwent ileostomy but all patients survived and prospered. CONCLUSION: All patients do not present typical prenatal ultrasound findings of meconium peritonitis. Therefore, even in pregnancies associated with isolated ascites, meconium peritonitis should be taken into consideration. Favorable outcome of intrauterine meconium peritonitis is reassuring in prenatal counselling and stems from multidisplinary team approach.

		                        			Metastasis to the skin occurs rarely in gynecologic cancer. Although carcinoma of the cervix is the fifth most common malignancy in Korean women, cutaneous involvement originating from cervical cancer is unusual. Common pattern of occurrence is multiple nodule in abdomen, vulva, lower extremities. We report a case of metastasis from squamous cell carcinoma of cervix to vulva. The patient was diagnosed with cervical cancer IIA. The extensive skin lesion on the vulva occurred 3 months after neoadjuvant chemotherapy, radical hysterectomy and concurrent chemoradiation. We have experienced such a case and report the case with brief review of literatures.

		                        			We report a case of premature constriction of the fetal ductus arteriosus following maternal ingestion of a cyclooxygenase-2 (COX-2) inhibitor at 37 weeks' gestation. Fetal sonography at 38+2 weeks' gestation revealed tricuspid regurgitation, absent transpulmonary valve flow, right heart enlargement, and pericardial effusion. An immediate delivery resulted in a good postnatal outcome with dramatic improvement in the clinical and echocardiographic findings. Maternal exposure to Non-steroidal anti-inflammatory drugs (NSAIDs), especially late in gestation, can cause premature constriction of the ductus arteriosus, heart failure, and fetal death. Therefore, the use of NSAIDs late in gestation should be considered in limited cases with close fetal heart monitoring.

		                        			Eclampsia, defined as peripartum seizure activity commonly associated with hypertension, proteinuria and edema. Historically, eclampsia was believed not to occur more than 48 hours after delivery and late postpartum eclampsia was thought to be uncommon. However, recent evidence suggests that its incidence is increasing. In addition, clinical signs of late postpartum eclampsia may differ from that occurring during the pregnancy. In case of late postpartum eclampsia, headache and visual disturbance may precede seizure but classic preeclampsia signs as edema, proteinuria, and hypertension are not presented until shortly before seizure onset. So it should be needed that patient education about prodromal symptoms of late postpartum eclampsia, including headache, visual disturbance, and abdominal pain at the time of hospital discharge. We described a case of eclampsia occurring 11days after delivery without preeclampsia symptom including a review of the literature.

		                        			PURPOSE: Premature narrowing of the foramen ovale is rare but serious clinical entity. Prenatal narrowing or obstruction of the foramen ovale shows symptoms such as right heart failure, fetal hydrops, triscupid regurgitation, left heart obstructive disease, and supraventricular tachycardia. This study aimed to assess the prenatal diagnosis and postnatal clinical course of restrictive foramen ovale in utero in otherwise normal heart. METHODS: The subjects were five patients diagnosed with restrictive foramen ovale in utero from January 2001 to June 2005 at Chungnam National University Hospital. The diagnostic criteria was defined when the maximum diameter in a 4-chamber view is less than 2.5 mm and there is a continuous doppler velocity at the foramen ovale of more than 0.6m/s. RESULTS: At the time of diagnosis of restrictive foramen ovale, gestation age was 34~37 wks, and chief complaints were fetal arrhythmia(2 cases), pericardial effusion, Ebstein anomaly and subaortic stenosis. Two cases which were diagnosed fetal hydrops and supraventricular tachycardia delivered by emergent cesarian section. Five cases were found to have right heart dilatation on echocardiogram after birth, but right heart dilatation became normalized at day 7 after birth and the clinical courses were not eventful. CONCLUSION: Identifying an obstructed foramen ovale in the fetus warrants the further search for additional cardiac and extracardiac anomalies, which may alter the prognosis. Delivery should be induced if possible in cases of foramen ovale obstruction with signs of cardiac decompensation.

		                        			Meckel Gruber syndrome consisting of an occipital encephalocele, polycystic kidney disease and polydactyly is a rare autosomal recessive disorder with a recurrence risk of 25%. Targeted ultrasonography in late embryonic or early fetal stages of pregnancy has great importance in diagnosis and management of affected pregnancy in high risk groups due to incomplete genetic mapping of meckel syndrome gene (MKS). We present a case of prenatal diagnosis at 14 weeks' gestational age of Meckel Gruber syndrome in a woman, who experienced same disorder in her previous pregnancy.

		                        			BACKGROUND: Endometrial carcinomas are pathogenetically classified into two major types; endometrioid carcinoma (EC) and serous carcinoma (SC). The most frequently altered gene in EC is the PTEN tumor suppressor gene (TSG). SC is usually associated with mutations in the p53 TSG. METHODS: To further determine the role of PTEN and p53 mutation in endometrial carcinogenesis, the analysis of 33 endometrial carcinomas, including 28 ECs and 5 SCs, for loss of heterozygosity (LOH) on 10q23 and for mutation in all 9 coding exons of PTEN and the 5-8 exons of p53, using SSCP-PCR methods was carried out. RESULTS: LOH was detected in at least one marker in 12 (54.5%) of 22 ECs, but in only one (20.0%) of 5 SCs. Somatic PTEN mutations were detected in 10 (35.7%) of 28 ECs. PTEN was altered in 67.9% of ECs and in 20.0% of SCs, including those with 10q23 LOH. No PTEN mutations were found among the SCs. Somatic p53 mutations were detected in 2 (7.1%) of 28 ECs and 3 (60.0%) of 5 SCs. CONCLUSIONS: PTEN gene alterations contribute to the pathogenesis of an endometrioid subtype of endometrial carcinoma, but not to the serous type. In contrast, p53 plays an important role in the pathogenesis of SCs.

		                        			OBJECTIVE: Ovarian follicular atresia is initiated from ovarian granulosa cell apoptosis and macrophages exert their effects directly and/or indirectly on follicular atresia by phagocytosis of apoptotic bodies and secretion of various cytokines. In spite of the abundant data on ovarian macrophages, the presence of these cells within the follicles (i.e., among granulosa cells) remains controversial and the elimination methods of apoptotic bodies of atretic follicles, and the time and methods of penetration of macrophages into the follicles are not known completely. The aim of the present study is to demonstrate the presence of macrophage within the ovary as related to follicular atresia and the process of elimination of apoptotic granulosa cells by light and electron microscopy. METHODS: Using rat ovaries, immunohistochemical studies with rat macrophage monoclonal antibody ED1 for macrophages, and light and transmission electron microscopic observations were performed. RESULTS: In the rat, follicular atresia was initiated by the granulosa cell apoptosis which occured randomly within the all granulosa layers. Macrophages were observed within normal follicles, in antrum, granulosa and theca cell layers of atretic follicels, in interstium and in corpus luteum. Ultrastructurally, apoptotic granulosa cells showed characteristics, pyknotic nucleus and apoptotic body formation. Apoptotic bodies were eliminated by intact neighboring granulosa cells and macrophages. Intact granulosa cells ingested apoptotic bodies transiently, soon after they fell into the apoptosis. Finally, apoptotic bodies and degenerating oocytes were phagocytosed by macrophages. Macrophages entered the ovarian follicle at the time of initiation of granulosa cell apoptosis, and migrated with the progression of apoptosis. By elimination of theca cells, macrophages contributed the completion of follicular atresia. CONCLUSION: This study demonstrates both intact neighboring granulosa cells and macrophages in the elimination of apoptotic bodies in atretic follicles of the rat ovary. Macrophages are present within normal follicles, in atretic follicles such as antrum, granulosa and theca cell layers and in corpus luteum but are in different appearances according to their location in ovary. A number of macrophages appearing in atretic follicles and in corpora lutea suggest a role for macrophages in follicular atresia and corpus luteum differentiation. The function of macrophage according to their location in follicular development should be further studied.

		                        			OBJECTIVE: To analyze the indications, clinical features, cytogenetic results and complications of amniocentesis and to determine the efficacy of antenatal genetic amniocentesis. METHODS: We analyzed retrospectively maternal age, gestational age, indications, transplacental puncture, frequency, discoloration of amniotic fluid, karyotype and complications in 325 cases of prenatal genetic amniocentesis performed at Chungnam National University Hospital from January 2000 to December 2002. RESULTS: The most common age group was from 30 to 34 (31.4%) and mean age was 32.7 years old. 85.3% of cases were performed at 16th-20th gestational weeks. Abnormal maternal serum markers were the most common indication of amniocentesis (56.0%) and the second most common indication was maternal age over 35 (33.2%). Abnormal karyotypes were found in 12 cases (3.6%) and normal variants were 21 cases (6.5%). Numerical aberration were 9 cases (2.7%) and structural aberration were 3 cases (0.3%). Among the autosomal aberrations, Down syndromes were 5 cases and Edward syndrome was 1 case. Among the sex chromosomal aberrations, 47,XXX were 2 cases and Turner syndrome was 1 case. As the increasing maternal age, the incidence of abnormal karyotype was increased. Procedure-related complications occurred in 11.7% of cases and fetal loss rate was 7.4%. No significant associations were found between procedure-related complications and maternal age, gestational age, transplacental puncture, frequency, discoloration of amniotic fluid, and antibiotic treatment. CONCLUSION: Amniocentesis is useful for prenatal genetic diagnosis in pregnancies with increasing risk of chromosome aberrations, such as advanced maternal age, abnormal maternal serum markers or abnormal US findings. Further studies are necessary to identify risk factors of complications after invasive procedure.
