Clinical Practice Patterns of Hypertensive Disease in Pregnancy among Korean Obstetricians

Purpose@#The purpose of this study was to investigate the clinical practice patterns of Korean obstetricians and gynecologists the diagnosis and management of hypertensive disease in pregnant women. @*Methods@#From April 2015 to October 2015, questionnaire was distributed via email to obstetricians who were members of the Society for Maternal and Fetal Medicine. The survey consisted of 37 questions in 6 categories. Responses to the questions on the management of hypertensive disorders of pregnancy, from diagnosis to treatment, were evaluated. @*Results@#A total of 93 obstetricians and gynecologists responded to the survey. High blood pressure was allocated the highest priority as an index mainly used when deciding to hospitalize patients with hypertensive disease during pregnancy, followed by pregnancy symptoms, proteinuria, and blood test results. Calcium channel blocker (CCB) for oral administration and hydralazine for injection were preferred as antihypertensive drugs mainly used to control severe hypertension. Regarding the delivery method for hypertensive disease during pregnancy, in cases of preeclampsia, 63% of the respondents chose the delivery method according to the cervical status, and in cases of hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and eclampsia, which increased in severity, 52% and 31% responded that the delivery method was determined according to the cervical status, respectively. In cases of mild preeclampsia, the 70% of respondents preferred 37–38 weeks of gestation for the delivery time. Regarding the use of aspirin in patient with hypertension during pregnancy, 52% of the respondents occasionally administered aspirin, and in patients with a history of hypertensive disease during pregnancy, only 43% were administered prophylactic aspirin. @*Conclusion@#Domestic obstetricians regarded blood pressure as the most meaningful factor when treating women with hypertension during pregnancy and considered blood pressure control as important. The preferred antihypertensive agents were oral CCB and hydralazine injections, and the choice of delivery method was determined according to the condition of the cervix and severity of the disease. Even in women with high risk factors for preeclampsia, prophylactic aspirin was administered in as low as 50%, of patients, possibly may due to the absence of domestic guidelines for aspirin use during pregnancy. Korean guidelines for prophylactic aspirin administration during pregnancy is needed based on additional research on the efficacy of aspirin for domestic women in the future.

Expression of embryonic stem cell markers in human term placenta / 대한산부인과학회지

OBJECTIVE: To determine which compartments of placenta in the term pregnancy express the embryonic stem cell markers. METHODS: We have used immunohistochemical methods with antibodies to embryonic stem cell surface antigens, TRA 1-60 (Tumor rejection antigen 1-60), TRA 1-81 (Tumor rejection antigen 1-81), SSEA-3 (stage-specific embryonic antigen-3) and SSEA-4 (stage-specific embryonic antigen-4), to identify and localize stem cells in the term placenta. RESULTS: Stem cell marker-positive cells were found in all layer of placenta. Amnionic epithelial cells was immunoreactive with TRA 1-60, TRA 1-81. Amnionic mesenchymal stromal cells was immunoreactive with TRA 1-81. Chorionic mesenchymal stromal cells was immunoreactive with TRA 1-60 and TRA 1-81. SSEA-3 and SSEA-4 were not stained at any compartment of the term placenta. Compartment that was stained most strongly by TRA 1-60 was the amnionic epithelial cells layer. Compartment that was stained most strongly by TRA 1-81 was the chorionic mesenchymal stromal cells layer. CONCLUSION: The mesenchymal stroma cells of the amnion and chorion as well as amnionic epithelial cells may be useful source of pluripotent stem cells in the term placenta.

Clinical significance of oligohydramnios in intrauterine growth restriction / 대한산부인과학회지

OBJECTIVE: This study was performed to prove the significance of the oligohydramnios in the intrauterine growth restriction. METHODS: Eighty two patients were identified to have intrauterine growth restriction with oligohydramnios (Group of IUGR+Oligihydramnios) and fifty six patients were identified to have intrauterine growth restriction without oligohydramnios (Group of IUGR) on ultrasound examination from January 1st, 2005 to December 31st, 2007 at St. Vincent Hospital of Catholic University of Korea. Perinatal outcomes were compared between two groups. RESULTS: Statistically significant differences were not shown between two groups in the maternal characteristics and fetal clinical features except amniotic fluid index and the duration between diagnosis and delivery. The incidence of hyperbilirubinemia and complications in the urogenital system were significantly increased in the group of IUGR+ Oligihydramnios. The other complications were not shown significant difference between two groups. CONCLUSION: Oligohydramnios may not seem to be significant predictor of adverse neonatal outcome of IUGR except the development of hyperbilirubinemia and urogenital complications.

TSH and Free T4 Concentrations in Korean Pregnant Women / 대한주산의학회잡지

PURPOSE: To determine the means, medians and reference intervals for TSH (thyroid-stimulating hormone) and fT4 (free thyroxine) for each month of gestation and for three trimesters in Korean pregnant women. METHODS: Serum samples were collected from 265 pregnant women with singleton gestation. Levels of TSH, fT4 were measured by immunoassay. After exclusion of subjects with positive antimicrosomal autoantibodies, the means, medians and reference intervals based on 2.5th and 97.5th percentiles for TSH, fT4 were determined. RESULTS: The study population consisted of 94 women in first trimester, 49 women in second trimester, and 122 women in third trimester. The trimester-specific reference intervals were: TSH (1st trimester: 0.03~2.72, 2nd: 0.27~2.29, and 3rd: 0.03~2.88 mIU/L), fT4 (1st trimester 4.50~19.75, 2nd: 4.70~12.98 and 3rd: 5.07~11.84 pg/mL). fT4 levels were significantly lower in the second and third trimesters. TSH levels were lower in the first trimester than second and third trimester, with gradual elevation in the second and third trimester. CONCLUSION: Levels of TSH, fT4 during pregnancy differ from those in non-pregnant women. Gestational age specific reference intervals will play a cental role in screening and diagnosis of thyroid disorders. Further studies for normal reference ranges during pregnancy are needed to create reference intervals in Korean pregnant women.

Severe preeclampsia at 16 weeks' gestation associated with a partial hydatidiform mole and bilateral theca-lutein cysts / 대한산부인과학회지

We present an unusual case in which a patient was diagnosed with the preeclampsia associated with a partial hydatidiform mole and bilateral theca-lutein cysts. The patient newly developed proteinuric hypertension at 16 weeks' gestation. Ultrasound findings showed small multiple cystic spaces in the placenta and a live singleton fetus. Triploid 69, XXX was confirmed at karyotype analysis. Intrauterine fetal death was found at 18 weeks' gestation and termination of pregnancy was performed, and a partial hydatidiform mole was confirmed at pathologic examination. Torsion of bilateral theca-lutein cysts was developed at postpartum one week. Detorsion and aspiration of the bilateral theca-lutein cysts were performed under the laparoscopy.

Differential gene expression of transglutaminase 2 in term pregnancy with and without labor / 대한산부인과학회지

OBJECTIVE: Our purpose was to investigate transglutaminase 2 (TGM2) mRNA and protein expressions in term placentas and fetal membranes delivered with labor compared to no labor. METHODS: Samples were obtained from five cases delivered with labor and five cases delivered without labor after 38 weeks of gestation. Each sample was collected from amnion, chorion, central and peripheral portion of the basal plate of placenta. Real time polymerase chain reaction (RT-PCR) was done to analyze mRNA expression of TGM2. Western blot was done and TGM2 protein level was detected. Mann-Whitney U test was used for statistic analysis. RESULTS: In labor group, TGM2 mRNA expressions were decreased compared to no labor group in 3 sampling sites except chorion (0.66+/-0.10 vs 1.29+/-0.12 in peripheral placenta, 0.67+/-0.23 vs 1.02+/-0.02 in central placenta, 0.70+/-0.16 vs 1.04+/-0.05 in amnion in contrast with 1.62+/-0.64 vs 1.56+/-0.21 in chorion). TGM2 protein expressions of four differential portions were decreased in all labor groups (1.05+/-0.35 vs 1.27+/-0.19 in peripheral placenta, 0.69+/-0.84 vs 0.84+/-0.31 in central placenta, 0.33+/-0.15 vs 0.39+/-0.33 in amnion, 0.96+/-0.18 vs 1.77+/-0.61 in chorion). CONCLUSIONS: This result suggests that TGM2 might involve in labor progress of term pregnancy.

Perinatal outcomes of birth weight discordance according to the chorionicity / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to examine the association between intrapair birth weight discordance and perinatal outcomes according to the chorionicity. METHODS: Twin births in St. Vincent's Hospital of Catholic University of Korea for the period 2000~2007 were retrospectively studied. Discordance was defined as an intertwin birth weight difference > or =20% and concordance was defined as weight difference <20% calculated from the larger newborn. Perinatal outcomes were compared between discordant and concordant pairs in monochorio-diamnionic and dichorionic twins. RESULTS: Among 38 monochorionic twin births, 34.2% was discordant and 66.8% was concordant. Among 144 dichorionic twin birth, 9.9% was discordant and 91.9% was concordant. The incidences of intrauterine fetal death (FDIU), twin-to-twin transfusion syndrome (TTTS), intrauterine growth restriction (IUGR) and neonatal hypoglycemia of discordant group of monochorionic twins were statistically increased compared with concordant group of monochorionic twins. The incidences of IUGR and neonatal hypoglycemia were statistically increased in the discordant group of dichorionic twins compared with concordant group of dichorionic twins. The others were not shown statistically significant between two groups in the both chorionic twins. CONCLUSIONS: Birth weight discordance in monochorionicity seems to predict fetal death, TTTS, IUGR and newborn hypoglycemia. Birth weight discordance in dichorionicity does not seem to be good predictor of adverse perinatal outcomes except IUGR and neonatal hypoglycemia.

Analysis of gene expression in placenta of severe preeclampsia / 대한주산의학회잡지

OBJECTIVE: This study was designed to detect genes specifically expressed in severe preeclamptic placentas. METHODS: Placenta tissues were collected immediately after delivery from 5 preeclamptic patients and 5 normal pregnant women. Total RNAs of each placenta were extracted and hybridized for a cDNA microarray. Of the microarray data, four up-regulated genes (DSCR4, GPA, PCDHGB1, Hemogen) and four down-regulated genes (IL1R2, MGST1, GAS1 GREB1) were selected and reverse transcriptase-polymerase chain reaction was used to confirm the results of cDNA microarray. RESULTS: The expression fold for each up-regulated gene was 2.2 times for DSCR4, 2.7 times for PCDHGB1, 3.5 times for Hemogen, 5.2 times for GPA on the cDNA microarray. The expression fold for each down-regulated gene was 3.3 times for IL1R2, 4.2 times for MGST1, 4.9 times for GAS1 and 2.3 times for GREB1 on the cDNA microarray. The expression fold for each up- regulated gene was 5.21 times for DSCR4, 3.01 times for PCDHGB1, and 4,53 times for Hemogen and 2.2 times for GPA on RT-PCR. The expression fold for each down-regulated gene was 2.7 times for IL1R2, 2.22 times for MGST1, 2.53 times for GAS1 and 1.83 times for GREB1 on the RT-PCR. CONCLUSION: DSCR4, PCDHGB1, Hemogen and GPA as the up-regulated genes and IL1R2, MGST1, GAS1 and GREB1 as the down-regulated genes, which were found and selected by the cDNA microarray, might be considered to be novel biomarkers for preeclampsia.

Analysis of clinical characteristics of cornual pregnancy / 대한산부인과학회지

OBJECTIVE: To determine the efficacy of ultrasonogram in the detection of cornual pregnancy and the factors that might be affected on early diagnosis. METHOD: We studied 26 cases which were diagnosed as a cornual pregnancy from Jan, 1, 2000 to Dec, 31, 2004 at department of Obstetrics and Gynecology, St. Vincent's Hospital, the Catholic University of Korea. We compared two groups about clinical characteristics and outcomes. One group (A group) was diagnosed as cornual pregnancy before beginning of treatment, another group (B group) was not diagnosed as cornual pregnancy until operation. RESULTS: A group was 8 cases (30.8%) and B group was 18 cases (69.2%). There were no significant differences in age (33.0+/-6.21 years : 31.0+/-5.82 years), duration of amenorrhea (7.32+/-1.07 weeks : 8.90+/-5.44 weeks), previous cesarian section history (25.0% : 27.8%), present myoma (12.5% : 11.1%) and abdominal pain (50% : 77.78%), vaginal bleeding (50% : 55.6%), shock (0% : 27.8%) between two groups. There were significant differences in parity (1.63+/-0.74 : 1.0+/-0.77, p=0.032), number of abortions (2.25+/-1.16 : 1.11+/-1.18, p=0.016), previous history of ectopic pregnancy (37.5% : 0%, p=0.022). Of the method of treatments, only cornual resection (50% : 94.4%) showed significant differences between two groups. CONCLUSION: 30.8% of cornual pregnancy was early diagnosed by ultrasonogram. The important early detective factors for cornual pregnancy might be parity, previous ectopic pregnancy history and abortion history. Therefore if the patient has the previous ectopic pregnancy and abortion history, she can visit early to the hospital and the doctors do pay attention to the possibility of cornual pregnancy.

Impact of Maternal Age of 40 Years or Older on Pregnancy Outcomes / 대한주산의학회잡지

OBJECTIVE: The aim of this study was to examine the effects of maternal age on perinatal and obstetric outcomes with respect to maternal age older than 40 years. METHODS: A retrospective review of maternal and newborn medical records of women who delivered their babies in the hospitals of the Catholic University of Korea between January 1, 2000 and July 1, 2005 was conducted to compare pregnancy complications and perinatal outcomes in three age groups; women aged 25~29 years (group A; n=214), those aged 35~39 years (group B; n=276), and those aged 40 years and older (group C; n=347). RESULTS: The incidences of GDM (gestational diabetes mellitus), preterm birth and cesarean section in group C were by far the greatest among the three groups. The incidence of postterm delivery in group A was the highest among the three groups. Previous cesarean section and elderly gravida were the most frequent causes of cesarean section in group C. The incidences of low birth weight (<2,500 g) and the NMICU(neonatal medical intensive care unit) admission rate in group C were higher than those in group B, but not significantly different from those in group A. CONCLUSION: Maternal ages of 35~39 years do not appear to be associated with adverse perinatal and obstetrical outcomes. Maternal ages of over 40 years influence the incidences of PIH (pregnancy induced hypertension), GDM, preterm birth, cesarean section, placenta previa, low birth weight and NMICU admission.

A case of thoraco-omphalopagus with omphalocele with 3D ultrasonography and MRI / 대한산부인과학회지

One of the most interesting congenital malformations is a conjoined twin. Conjoined twins are a rare occurrence in obstetric practice. More commonly known as Siamese twins, this phenomenon is shrouded in mystery and considered a curiosity by general public. Current technology is providing a basis for earlier diagnosis and a better prognosis. Frequently, the twins are born dead, but there are a few cases in which the twins survive. We present a case of thoraco-omphalophagus with omphalocele in 35 years old woman at 25weeks 5 days gestation by 3-D ultrasonography and MRI.

The significance of maternal serum and umbilical cord blood leptin concentration with intrauterine fetal growth restriction and/or preeclampsia / 대한산부인과학회지

OBJECTIVE: To ascertain whether fetal growth restriction with or without preeclampsia is associated with alteration of leptin concentration in maternal and umbilical cord serum. METHODS: Maternal serum and umbilical cord blood leptin concentrations were determined by ELISA assay in 25 women with singletone pregnancies complicated by fetal growth restriction without preeclampsia (IUGR), in 11 women with singletone pregnancies complicated by fetal growth restriction with preeclampsia (IUGR+PE), in 9 women with singletone pregnancies complicated by preeclampsia without fetal growth restriction (PE), and in 13 women with uncomplicated singletone pregnancies (Control). RESULTS: Maternal weight and BMI before pregnancy and in delivery were significantly different among groups. The lowest weight and BMI before pregnancy and in delivery was group IUGR. Neonatal birth weight was significantly different among groups. The lowest birth weight was group IUGR+PE. Maternal serum leptin concentration and umbilical cord leptin concentration were not significantly different among groups. Maternal serum leptin levels were not significantly correlated with maternal BMI or with neonatal birth weight. Umbilical cord blood leptin levels were significantly correlated with neonatal birth weight. CONCLUSION: Maternal serum leptin concentration and umbilical cord blood leptin levels were independent of presence of preeclampsia and/or IUGR. Umbilical cord blood leptin reflects neonatal birth weight.

The risk factors of emergency cesarean hysterectomy for placenta previa / 대한산부인과학회지

OBJECTIVES: The purpose of this study is to investigate the clinical risk factors of emergency cesarean hysterectomy in patients with pregnancies complicated by placenta previa and whether the third trimester transvaginal ultrasonographic findings of placenta previa would predict emergency cesarean hysterectomy. MATERIALS AND METHODS: Between January 1995 and March 2005, we retrospectively reviewed the records and compared between patients with pregnancies complicated by placenta previa who underwent cesarean hysterectomy and patients with pregnancies complicated by placenta previa who did not undergo cesarean hysterectomy. RESULTS: There were 314 had placenta previa and 34 patients were performed cesarean hysterectomy (10.83%). There were significant differences on the basis of maternal age (31.53+/-4.41 vs 34.06+/-4.12, p<0.05), parity (0.81+/-0.70 vs 1.29+/-0.63, p<0.05) , the number of cesarean section (0.36+/-0.56 vs 0.91+/-0.75, p<0.05), previous history of placenta previa and presence of placenta accreta, but not on the basis of gestational age, the number of antenatal vaginal bleeding, the number of abortions and emergency operation between two groups. On the basis of third trimester transvaginal ultrasonographic findings, significant differences were found on the distances from the internal os of cervix (1.18+/-3.66 vs 2.67+/-2.94, p<0.05) and thickness of lower placental edge. However, the presence of lacuna in the lower placenta was not associated with emergency hysterectomy. CONCLUSIONS: Patients with placenta previa are at a higher risk of undergoing cesarean hysterectomy when they are associated with placenta accreta, thick lower placenta edge, and positively longer distance to the internal os of cervix. The other clinical factors such as maternal age, parity, the number of cesarean section and previous history of placenta previa might be associated the risk of cesarean hysterectomy.

Differential Gene Expression in Placenta of Term Pregnant Women with and without Labor using cDNA Microarray / 대한주산의학회잡지

OBJECTIVE:cDNA microarray technology was used to comprehensively analyze the gene expression in the placenta of term women with labor compared to without labor. METHODS:Placental tissue was obtained from patients in spontaneous labor (n=5) and those not in labor (n=5) during Cesarean section of full term pregnancy. mRNA levels were examined through cDNA microarray using Agilent GeneSpringGX 7.3 (Agilent technology, USA). SPSS 11.0 was used for statistical analysis. RESULTS:Among total 38,467 genes, 2,374 genes were detected to be up-regulated in labor samples, while 12 genes were down-regulated. 40 genes of them were identified as significantly up-regulated in levels of expression (up-regulated > or =5.0 fold, p<0.05). According to gene ontology analysis, they are associated with variable cell biologic functions including apoptosis, signal transduction, metabolic process, immune response, and transcription, etc. CONCLUSION:This study suggests that our results could provide interesting clues to understanding the initiation and the process of normal labor and might lead to further studies in a more targeted fashion.

Two Cases of Acute Interstitial Pneumonia During the Second Trimester of Pregnancy / 대한주산의학회잡지

We present two cases of acute interstitial pneumonia (AIP) during the second trimester of pregnancy managed by mechanical ventilation, high dose corticosteroids. We described clinical course, laboratory data and imaging studies. Case 1) A 29-year-old woman, G1P1, was referred for aggravated continuous coughing, sputum and dyspnea, pleuritic chest pain and mild fever for 3 weeks at 24(+3) weeks of gestation. There were coarse breathing sounds with crackles on the both lung field. Her chest X-ray showed diffuse haziness in both lungs with suspicious nodular opacities and suggested pneumonia. HRCT showed diffuse ground glass opacities with interstitial thickening and suspicious fine nodular infiltration in both lungs suggesting acute interstitial pneumonia combined with ARDS. Because her symptoms were more aggravated, she was performed mechanical ventilation treatment. After that, she was performed cesarean hysterotomy and delivered a dead male 850grams. After her symptoms were much more improved. All antibiotics were stopped and reduced the doses of steroids, she was discharged with t-tube capped state. Case 2) A 33-year-old woman, G1P1, was referred for continuous coughing, sputum and dyspnea for 3 months and low abdominal discomfort at 24(+4) weeks of gestation. There were coarse breathing sounds with rales on the both lung field. Her chest X-ray showed diffuse haziness in both lungs with suspicious nodular opacities and suggested interstitial pneumonia. HRCT showed diffuse ground glass opacities with some intralobular and interlobular interstitial thickening and suspicious fine nodular infiltration in both lungs suggesting acute interstitial pneumonia or miliary TBc combined with ARDS. She was treated with antibiotics, oxygen, high dose corticosteroids, and tocolytics. There was no evidence of TBc in the bronchoscopy. She showed decreased mentality and decreased O2 saturation below 90% in spite of mechanical ventilation, high dose steroids and IVGV therapy. She delivered a boy of 870 g (Apgar score 1/5). After delivery, she was expired due to combined aggravating DIC. Her baby was expired at the next day, too. The outcome of AIP is fatal, reporting 59~100% mortality rate. The clinical course, laboratory data and treatment are not well established due to rarity of this disease entity. Chest X-ray and HRCT may be helpful in diagnosis and high dose steroid and immunosuppressive agents usually used but the efficacy is not guaranteed.

Pregnancy Outcome in Renal Transplant Recipients: A Retrospective Study / 대한주산의학회잡지

OBJECTIVE: The aim of our study was to identify graft, obstetric and maternal outcomes of pregnancies in renal transplant recipients at our center. METHODS: A 14-year retrospective study between January 1990 and December 2003, 224 women 15 to 45 years of age had transplantation and were analyzed the outcomes of pregnancies, obstetric complications and graft function. RESULTS: Thirty-four pregnancies occurred in 21 of 224 patients. The mean age at the time of conception was 29.5 years (21 to 36 years) with a mean interval of 61.9 months (one to 162 months). In the pregnancy outcome, there were the 23 live births (67.6%) included 13 preterm and 10 term deliveries, 3 spontaneous abortions (8.8%), 7 artificial abortions (20.5%) and one case of ectopic pregnancy (2.9%). Obstetric complications were; preeclampsia (39.1%), preterm labor (43.4%), urinary tract infections (38.2%) and gestational diabetes (8.6%). Nine pregnancies within 2 years of transplantation had the permissible obstetric outcomes comparing with the others after 2 years (spontaneous abortion: p=0.77, artificial abortion: p=0.88, live birth: p=0.36). In twelve pregnancies appearing renal dysfunction associated with pregnancy, the abortion rate was increased comparing the others with stable renal function (p=0.006). Pre-pregnancy serum creatinine > or =1.4 mg/dl was associated with increased preterm delivery, but not significant (50.0% vs 28.5%, p=0.30). In graft function, serum creatinine 3~6 postpartum was significantly increased comparing pre-pregnancy levels (p=0.04). Five cases of 7 patients with acute rejection episode associated with pregnancy conceived after 4 years of transplantation. Two-year graft survival after delivery was 95.2% (20/21) and chronic rejection and graft failure was diagnosed in one case at postpartum 14 months. CONCLUSION: These findings suggest that, if the graft function is stable, pregnancy within 2 years after renal transplantation might be safe. Pregnancy does not appear to have adverse effects on long term graft survival.

A case of ovarian pregnancy with focal adenomyosis mimicking cornual pregnancy that managed by laparoscopy / 대한산부인과학회지

Ovarian pregnancy is rare form of ectopic pregnancy occurring in 0.5-1% of all ectopic pregnancies. But the presenting symptom is very similar and difficult to distinguish with other forms of ectopic pregnancy. We report a case of ovarian pregnancy mimicking cornual pregnancy managed with laparoscopy. Early detection is important role in preserving fertility to avoid the ablation of functional ovarian tissue. The diagnostic criteria, etiology, and management are discussed.

Clinical Outcome of Pregnancy-associated Aplastic Anemia Treated with Supportive Anagement / 대한주산의학회잡지

OBJECTIVE: Pregnancy-associated aplastic anemia remains a rare occurrence. The aim of this study was to examine the maternal and fetal outcomes of pregnancy-associated aplastic anemia treated with supportive care. METHODS: From January 1995 to December 2004, a total of 14 women newly diagnosed with pregnancy-associated aplastic anemia were recruited for the study. RESULTS: Eleven (78%) of the 14 women were diagnosed with pregnancy-associated aplastic anemia during the second or third trimester. There were eight severe cases; three of which were diagnosed at the initial presentation. All 14 women had conservative management with transfusions but not specific immunological or hormonal therapies during pregnancy. Blood transfusions were performed prenatally in seven mothers and perinatally in 13. Of the 12 patients eligible for follow-up, one achieved complete remission and another eight showed partial remission after delivery. During the follow up period, there was no case of maternal-fetal death in our series. The pregnancies were continued uneventfully in most cases. CONCLUSIONS: This study demonstrated favorable maternal and neonatal outcomes with transfusion support alone for pregnancy-associated aplastic anemia. Therefore, pregnancy continuation with meticulous blood support should be considered, rather than therapeutic termination, for women with pregnancy-associated aplastic anemia.

Effects of magnesium sulfate on VEGF and Caspase-3 of HUVECs (Human umbilical vein endothelial cells) / 대한주산의학회잡지

OBJECTIVES: To determine the effects of magnesium sulfate on Caspase-3 and Vascular endothelial growth factor (VEGF) of human umbilical vein endothelial cells (HUVECs) under presence or absence of Tumor necrosis factor (TNF-alpha). METHODS: HUVECs were isolated from normal term umbilical cords and cultured in several physiolo gically relevant concentrations of magnesium sulfate with or without exposure of TNF-alpha. The concentrations of VEGF and caspase-3 were estimated by colorimetric assay and ELISA assay, respectively. RESULTS: The concentration of VEGF in HUVECs significantly increased in the presence of TNF-alpha compared with in the absence of TNF-alpha. However, the concentration of VEGF did not show significant difference in several concentrations of magnesium sulfate concentrations with addition of TNF-alpha and it showed the lowest concentration under 4 mM and 8 mM of magnesium sulfate concentration without addition of TNF-alpha. The concentration of caspase-3 in HUVECs did not show statistically significant difference with the addition of TNF-alpha and magnesium sulfate. CONCLUSION: TNF-alpha induce HUVECs to stimulate the VEGF, and magnesium sulfate might not have the effects on the expression of VEGF with addition of TNF-alpha However, the concentration for treatment of magnesium sulfate inhibits the expression of VEGF without addition of TNF-alpha. Magnesium sulfate might not have an effect of the expression of caspase-3 with or without addition of TNF-alpha.
