N/A Objective : To evaluate the invasive capacity of trophoblastic cells when treated with HGF, and see whether HGF induces c-met expression in vitro. Methods : HT cell line was treated with recombinant HGF (rHGF) at different concentrations (0, 10, 50 and 100 ng/mL) and cultured for 24 hours. To evaluate according different time of culture, HT cell line was pre-treated with 50 ng/mL rHGF and cultured for 24, 36, 48 and 72 hours. We analyzed the expression of c-met mRNA using reverse transcriptase-polymerase chain reaction and the expression of c-met protein using western blot in each samples. We also observed cellular invasion capacity through the invasion assay under a microscope and confirmed 72 kDa gelatinase and 92 kDa gelatinase expression patterns by zymography assay. Results : The expressions of c-met mRNA and protein were increased in all concentrations of rHGF, compared with that of normal control although it was not in dose-dependent fashion. In invasion assay, the number of invaded HT cells were increased in dose-dependent fashion, compared with that of normal control. In zymography ssay, the expression of 72 kDa gelatinase was increased in dose-dependent fashion, compared with the control. However, 92 kDa eglatinase was not detected in any studied group. Conclusion : These results suggests that HGF might be related to upregulation of trophoblast cell invasiveness by activation of c-met and subsequent induction of 72 kDa gelatinase.

N/A Objective : This study was performed to investigate the influence of hepatocyte growth factor (HGF) on matrix metalloproteinase (MMP), which are related in the lysis process of tissue during the invasion of trophoblasts. Method : HT cell line was treated with recombinant HGF (rHGF) of different concentration (0, 10, 50 and 100 ng/mL) and was cultured for 24 hours to check the changes in the expression of MMP-2 and MMP-9. Also, HT cell line was treated with recombinant HGF 50 ng/mL and was cultured for 24, 36, 48, and 72 hours to check the changes in the expression of MMPs according to the different time span. Total RNA were extracted from each cultured sample and RT-PCR and Western blotting were used to analyze the expression of MMP-2 and MMP-9. Results : MMP-2 mRNA expression with treated rHGF showed increase of 2, 2.5 and 2.2 times with the increase of concentration level of 10, 50 and 100 ng/mL accordingly, while MMP-2 protein expression were increased 1.4 and 1.5 times in 50 ng/mL and 100 ng/mL of rHGF respectively compared with that of normal control. MMP-9 mRNA showed no significant changes in its expression with all different levels of concentration, while MMP-9 protein showed 1.5 times increase with 10 ng/mL rHGF but 0.4 times decrease with 100 ng/mL. MMP-2 mRNA expression treated with recombinat HGF were increased 1.6 times with 24 hour culture and 2.3 times with 36 hour culture. MMP-2 protein showed 1.9 times increase only for the case of 24 hour culture. MMP-9 mRNA expression of recombinant HGF-treated groups was decreased 0.7 times compared with that of control group in 36 hours. MMP-9 protein expression were increased by 1.2, 1.6 and 1.9 times as culture time increase to 36, 48, and 72 hours accordingly, compared with that of normal control. Conclusion : This result suggests that the HGF might partially regulate the invasion of trophoblasts through MMP-2 and MMP-9.

The relationship between level of milk composition and conditions of ovary and uterus were analyzed in Holstein cows at seven farms participating in a reproductive herd health management program. Milk data were taken from 503 early lactating cows between 30 and 60 days in milk with reproductive examination with ultrasonography from september 1999 to August 2000. Milk fat, protein and solid-not-fat concentration in the herds were $3.70{\pm}1.08%$, $2.97{\pm}0.35$, and $8.41{\pm}0.61%$, respectively. The reproductive disorder relative to normal cows had higher risk in the cows that the level of protein was lower than 2.70%. Also, the higher milk fat than 4.50% were associated with a higher risks in the uterine disease and follicular cysts. Therefore, the cows with the fat to protein ratio of > 1.30 had higher risks for reproductive disorder such as cystic ovarian diseases, inactive ovaries and endometritis. These results indicated that cows diagnosed with reproductive disorder were energy deficient prior to reproductive disorder diagnosis. Consequently, milk fat and protein analyses may be used serve as a monitoring tool for condition of ovary and uterus in early lactating cows

There is high prevalence of HBV infection in Asian countries including South Korea. In fact, 8% of Koreans are HBV carriers, and 20-25% of them progress to liver cirrhosis. Liver cirrhosis, known to be the last stage of chronic liver diseases, is the most prominent cause of death in Korean males in their forties. However, women participation to social activities increased and also increased psychological stress that changed life style now days, and due to increased alcohol consumption liver disease has become a serious problem in korean women population. But as liver cirrhosis usually occurs after the menopause, and decreased fertility in cirrhotic patients, pregnancy in women with liver cirrhosis is rare. However, improved general care increased pregnancy rates and reports of pregnancy in women with liver disease worldwide. Studies on the effect of liver cirrhosis on pregnancy and the effect of pregnancy on the clinical progression of liver cirrhosis have not been well established, and the continuation of pregnancy in a patient with liver cirrhosis has been controversial. Recently, it has become favorable for the argument that pregnancy can be kept as long as liver function is maintained at certain level and portal hypertension is mild. The most common and fatal maternal complication is gastrointestinal hemorrhage. It increases maternal mortality and intrauterine developmental defect resulting in neonatal morbidity. Although South Korea is an area of high prevalence of HBV infection, there are few reports of pregnancies in women with liver cirrhosis. Recently, we have experienced the 3 cases of pregnancies in women with progressive liver cirrhosis who became pregnant. Although thrombocytopenia and increased coagulopathy complicated the pregnancy course, all women delivered healthy babies and were discharged in good condition.

목적: 태아 심박동(fetal heart rate; FHR)은 자율신경계의 조절로 나타나는 현상으로 정상 심박동은 자체의 주기성, 교감 신경 또는 미주 신경 및 부교감 신경으로부터 영향을 받는다. 자율신경 하에 조절되는 심장박동은 성인의 경우 나이 성별에 따른 차이가 있으며, 성별에 따른 자율신경의 생리 작용이 다르다는 것을 알 수 있다. 이에 저자들은 태아 성별에 따른 임상적 여러 변수들 그리고 태아 심박동과 차이를 연구하였다. 연구 방법: 가톨릭 의과대학 산부인과학 교실에 산전 진찰 및 분만을 위해 내원한 산모 중 전자식 태아감시 장치를 시행하였고, 본원에서 분만하여 신생아 임상 소견을 알 수 있었던 317명의 667개의 태아 심박동 자료를 대상으로 하여, 기초 태아 심박동수, 태아 심박동 증가, 태아 심박동 감소, Percent acceleration time(PAT) 및 Percent deceleration time(PDT)를 계산하였고, 변이도로 표준 편차, Mean minute range(MMR)의 장기변이도(LTV) 및 단기변이도(STV)를 계산하였다. 결과: 분석 결과 남아 분만군과 여아분만군의 비교에서 기초 태아 심박동수 137.64±13.68 bpm, 140.51±12.43bpm(P=0.007), PAT는 6.10±4.00bpm, 4.90±3.34bpm(P=0.001), 그리고 PDT는 7.50±8.70bpm, 6.18±7.70bpm(P=0.039)으로 유의한 차이가 있었으나, 표준 편차는 8.84±10.11bpm, 8.11±3.56bpm, LTV는 80.38±62.79msec과73.65±54.60msec, STV는 14.06±9.79msec과 13.33±12.32msec로 차이가 없었다. 결론: 위의 결과로 남아와 여아의 태아 심박동은 차이가 있으며, 이는 발생 시기부터의 부교감 신경과 교감 신경의 발달 차이로 인한 심장 및 체강의 연결계의 차이가 임신 기간 중에 발생한는 것이 원인으로 사료 된다. Objectives: The purpose of this study is to analyze the previously unreported effect of fetal sex on the fetal heart rate and to measure its magnitude in relation to the effects of other independent clinical variables. Methods: Three hundred and seventeen pregnant women who were able to provide electronic fetal heart rate monitoring were evaluated. On the basis of fetal sex after birth, 167 pregnant women who delivered male neonate were for males group and 146 examples who delivered female neonate were for female group. We analyzed fetal heart rate data using the Catholic Computer Assisted Obstetric Diagnosis System(CCAOD). Results: Female fetuses had significantly faster basal heart rate(140.51±12.43bpm) than male fetuses(137.64±13.68 bpm).(P=0.007) Percent acceleration time(PAT) increased significantly for males(6.10±4.00bpm), comparing to females(4.90±3.34bpm).(P=0.001) Also percent deceleration time(PDT) was significantly higher in male fetuses(7.50±8.70bpm) than female fetuses(6.18±7.70bpm).(P=0.039) But there was no differences in standard deviation(SD)(8.84±10.11bpm, 8.11±3.56bpm), long term variation(LTV)(80.38±62.79msec, 73.65±54.60msec), and short term variation(STV)(14.06±9.79msec, 13.33±12.32msec) between male and female fetuses. Conclusion: The fetal heart rate of female fetuses differ from that of male fetuses. Computerized linear analysis and nonlinear analysis of antepartum fetal heart rate will need to take into account the multiple factors that influence the fetal heart rate to identify precisely which pattern predict clinical outcome.

We report a case of ring chromosome 13 with a distal deletion of 13q32.2→qter observed in a fetus who was referred to our institution at term due to severe growth restriction and multiple congenital malformations on ultrasonographic examination. This boy was born by vaginal delivery at 39 weeks in gestation. His weight, head circumference and height were less than the 3 percentile of gestational age. Apgar score was 7 at 1 minute and 9 at 5 minutes. He showed microcephaly, large forehead, low set ears, hypertelorism, flat nasal bridge, and micrognathia. The genitalia was ambiguous, showing severe hypoplasia of the penis. The anus was ectopic, displaced anteriorly from its normal position but with a normal opening and function. Neurologic examination was normal. Echocardiogram done at 2 weeks of life showed a persistent foramen ovale and a ventriculoseptal defect (type II) with increased pulmonary hypertension. MRI examination of the brain showed poorly demarcating corpus callosum suspecting agenesis of corpus callosum. Also, cerebellar vermis was small and hypoplastic, mimicking a variant form of Dandy-Walker malformation. MRI of the pelvis showed a tubular structure in pelvic cavity, suspicious of uterine remnant, between urinary bladder and rectum, and a inguinal hernia was noted in the left side. In the abdominal cavity enlarged adrenal glands were noted, and hormonal study showed elevated 17-α-OH-progesterone (168.9 ng/ml) with normal 17-KS and 17-OHCS levels. Gastrointestinal and urogenital system were otherwise normal. Cytogenetic analysis of the parents were both normal but the newborn showed 46, XY, r(13), de novo, with deletion points q32.2→qter. Our findings are in line with previous reports about chromosome 13 deletions, in which loss of the critical point leads to major malformations like brain anomalies and ambiguous genitalia.

Maternal serum α-fetoprotein (AFP) has been used for a long time for the prenatal diagnosis of neural tube defects in women at midtrimester of gestation. But AFP is elevated not only in cases of neural tube defects, but also in fetus with congenital nephrosis, abdominal wall defects, fetal demise, low birth weight or simply erroneously calculated gestational age. So, when maternal serum AFP is increased, gestational age of the fetus must be re-evaluated and targeted ultrasonographic evaluation is indicated to rule out neural tube defects. If NTDs are suspected or ultrasound is non-diagnostic, amniotic fluid AFP are measured and when AF-AFP is elevated, the presence or absence of acetylcholinesterase should be evaluated. The detection rate of open neural tube defects using amniotic acetylcholiesterase is reported to be as high as 96 to 99% with a 0.06% and 0.14% of false positive rate in amniotic fluids non-contaminated and contaminated by blood, respectively. We report a case with elevated mid-trimester MS-AFP, AF-AFP and positive amniotic acetylcholin- esterase, but in which repeated sonographic findings were normal, and result in delivery of a heathy baby without anomalies.
