N/A Objective: A dichotomous Thl and Th2 cytokine profile has been associated with reproductive failure and success, respectively. The purpose of our study was to determine the levels of Thl cytokine (IFN- y ) secreted by peripheral blood mononuclear cells (PBMCs) form women with unexplained recurrentabortion (URA) and fertile controls in response to trophoblast antigen. Methods: PBMCs were isolated from 30 nonpregnant women with URA and from 10 nonpregnant fertile controls. Following 4 days of culture (1 * 10(6) cells/mL) with and without a protein extract derived from a trophoblast cell line (30 ug/mL, protein). None of the women had allergies, atopy or recent infection. Cytokines were measured in supernatants with enzyme-linked immunosorbent assay (ELISA) kits. IFN- r kit was obtained from BOISOURCE (lower limit of sensitivity, 15.6 pg/mL for IFN- r ). All values below the lowest limit of sensitivity as determined by test kit standards were considered negative. The cytokine stimulation test is considered positive if the IFN- r concentration increases by 200% or more with the trophoblast antigen stimulation. Datas are presented as mean+ SEM. Nonparametric testing (Mann-Whitney U) was used for analysis with P<0.05 considered statistically significant. Results: The Thl-type cytokine (IFN- r ) was detected in 20(67%) of 30 supernatants from women with URA. In contrast, 2 (20%) of trophoblast-activated PBMC culture supernatants from the 10 parus women with normal reproductive histories was detected IFN- r and but were significantly lower than levels in women with URA who had secreted IFN- r upon trophoblast stimulation (99.80+ 18.17 pg/mL versus 166.47 + 36.96 pg/mL, p<0.05). Spontaneous secretion of IFN- r was significantly higher in culture supernatants from women with URA than in supernatants from women with successful reproductive histories (41.36.09+6.99 pg/mL versus 25.89+9.34 pg/mL, p<0.05). Conclusion: These data indicate that there are significant differences between women with URA and women with normal reproductive histories in their regulation of the Thl-cytokine (IFN- r) in response to trophoblast. Thl-type immunity to trophoblast is associated with URA and may play a role in reproductive failure.

The safety of ICSI as a novel procedure of assisted fertilization may be assessed by the health of the baby born. In order to evaluate the safety of ICSI, perinatal outcome and congenital anomaly of the babies born after ICSI were compared with those of babies born after IVF (control group). We analysed the clinical data from the obstetric and pediatric records, including the information obtained through telephone. The results are as follows; Mean gestational age $({\pm}SEM)$ and birth weight in singleton pregnancy were $38.8{\pm}1.9$ weeks and $3209.7{\pm}501.9gm$ in IVF group, $39.0{\pm}2.2$ weeks and $3289.9{\pm}479.5gm$ in ICSI group, respectively. Mean gestational age and birth weight in twins were $36.8{\pm}2.1$ weeks and $2512.8{\pm}468.0gm$ in IVF group, $36.5{\pm}2.8$ weeks and $2492.7{\pm}537.1gm$ in ICSI group. In IVF group, perinatal mortality rates were 8.5 in singletons and 56.6 in twins; for the ICSI singletons and ICSI twins, the perinatal mortality rates were 11.6 and 49.0, respectively. The incidence of congenital malformations was 3.6% (8/224) in IVF group and 2.1% (4/188) in ICSI group, there was no statistical difference (p>0.05, Fisher's exact test). The incidence of major congenital anomalies was 0.9% (2/224; pulmonary artery hypoplasia, renal cystic dysplasia) in IVF group and 1.1% (2/188; holoprosencephaly, Cri du chat syndrome) in ICSI groups (p>0.05, Fisher's exact test). Similarly, there was no significant difference in incidence of minor congenital anormalies 2.7% (6/224) in IVF group and 1.1% (2/188) in ICSI group respectively (p>0.05, Fisher's exact test). In conclusion, there was no difference in the perinatal outcome and the incidence of congenital anomalies between the babies born after ICSI and those after conventional IVF.

N/A Objeetive: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. Methods: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. Results: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). Conclusion: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.

목적 : 제왕절개 분만 후의 치골관절 이개는 국내에서 보고된 적이 없다. 본원에서 체험한 례를 중심으로 질환의 조기 발견 및 방지를 위한 목적으로 임상적 특징, 치료결과, 발병률 및 위험인자를 확인하기 위하여 본 연구를 하였다.방법 및 재료 : 본원에서 1997년 부터 1999년까지 제왕절개 분만을 한 산모 8,089명을 대상으로 하였다. 진단기준은 1)임상적으로 골반 불안정성의 증상 및 이학적 검사 양성인 경우, 2)x-ray상 치골관절 간격 6mm이상, 혹은 상하이동 3mm이상, 혹은 천장관절 간격4mm이상인 경우로 하였다. 치골관절 이개가 있는 군(n=21)과 대조군(n=138) 사이에 위험인자들에 통계학적으로 유의한 차이가 있는지를 t- test 및 chi-자승 검사로 통계학적 분석을 하였다. 결과 : 치골관절 손상은 8,089 제왕절개 분만에 21례로 발병률이 제왕절개 분만 1,000에 2.6례였다. 치골관절 간격은 3mm부터 28mm까지 였으며, 8례에서 상하 이동을 관찰 할 수 있었다. 위험인자의 통계학적 분석에서는 산모의 과체중 및 임신중의 골반관절 이완증상의 기왕력이 유의한 유발 인자로 나왔다(P<0.05).결론 : 이상의 결론으로 제왕절개 분만을 한 경우에도 치골관절 이개가 생길 수 있으며, 위험인자가 포함되어 있는 경우에는 치골관절 이개의 발생 가능성을 예견하여, 조기 발견 및 치료를 하여 합병증을 예방 하여야 하겠다. Objective : The objectives of this study are to observe the clinical characteristics, outcome of treatment and incidence of diastasis of symphysis pubis after cesarean section, and to evaluate the risk factors of the lesion.Methods : 8,089 cesarean section cases of our center from 1997 to 1999 were reviewed. The diagnostic criteria of diastasis were; 1) positive signs and symptoms of pelvic instability, 2) radiological evidence of widening of symphysis pubis more than 6mm and/or vertical mobility more than 3mm, or widening of sacroiliac joint more than 4mm. Several factors that increase the risk of this lesion were reviewed and analyzed by t- test and chi-square test. Results : Twenty-one diastasis of symphysis pubis were diagnosed out of 8,089 cesarean section cases during that period and all were available for over one year follow-up. The widening of the joint ranged from 3mm to 28mm. Eight cases accompanied vertical mobility. The history of pelvic girdle relaxation during pregnancy and over weight gain were proved to increase the risk of the lesion (P<0.005).Conclusion : We should have in mind that diastasis of symphysis pubis after cesarean section delivery could be found and history of pelvic girdle relaxation symptom and overweight during pregnancy might be the risk factors. Further studies with more cases would be needed to disclose the etiology and risk factors.

Objective: To compare the pregnancy outcomes after in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI) between obstrucvtive and non-obstrucvtive azoospermia. Methods: From January 1994 to December 2002, 524 patients with obstructive azoospermia (886 cycles) and 163 patients with non-obstructive azoospermia (277 cycles) were included in this study. Microsurgical epididymal sperm aspiration (MESA) or testicular sperm extraction (TESE) in obstructive azoospermia and TESE in non-obstructive azoospermia were perfomed to retrieve sperm, which was used for ICSI and then fertilized embryos were transferred. The results of ICSI - fertlization rate (FR), clinical pregnancy rate (CPR), clinical abortion rate (CAR) and delivery rate (DR) - were statistically analysed in obstructive versus non-obstructive azoospermia. Results: There were no differences in the number of retrieved oocytes, injected oocytes for ICSI and oocyte maturation rate. FR was significantly higher in obstructive than non-obstructive azoospermia (71.7% vs. 61.1%, p<0.001). There was no difference in CPR per embryo transfer cycle. After pregnancy was established, however, CAR was significantly higher in non-obstructive than obstructive azoospermia (25.6% vs. 12.5%, p=0.004). DR per clinical pregnancy cycle was significantly higher in obstructive than non-obstructive azoospermia (78.0% vs. 64.4%, p=0.012). In the karyotype ananlysis of abortus, abnormal karyotypes were found in 75.0% (6/8) of obstructive and 55.6% (5/9) of non-obstructive azoospermia. Conclusion: Our data show significantly higher FR in obstructive than non-obstructive azoospermia. Though there was no differrence in CPR, CAR was significantly higher in non-obstructive than obstructive azoospermia. The abortion may be related to the abnormal karyotype of embryo, but further investigations are necessary to elucidate the cause of clinical abortion in azoospermia.

Objectives: We aimed to investigate the clinical effect of low-dose intravenous immunoglobulin treatment in unexplained recurrent spontaneous aborters (RSA) with elevated peripheral CD56+ natural killer (NK) cell levels and to determine the pre-conceptional NK cell percentage predictive of subsequent successful pregnancy outcome. Materials and Methods: Sixty four cases of unexplained recurrent miscarriage with elevated peripheral NK cells (>15%) were received low dose IVIg infusion at the dosage of 400 mg/Kg/month after confirmation of gestational sac and continued until 20 weeks. The patients were divided into two groups according to the pregnancy outcome: Group I was success of treatment defined as live birth at or after 25 gestational weeks and Group II was failure of treatment. The preconceptional levels of the peripheral blood NK cells were compared between two groups. Results: Fifty-three pregnancies resulted in live births after 25 weeks and 11 resulted in abortion (Overall success rate of IVIG treatment was 82.8%). Preconceptional CD56+ NK cell percentage in group II ($27.4{\pm}1.9%$) was higher than those in group I ($22.3{\pm}0.8%$). By using ROC curve, optimal discrimination between success and failure of treatment was achieved with ${\leq}27%$ of preconceptional NK cell percentage. Conclusion: In RSA patients with elevated NK cells, we suggest that preconceptional peripheral blood CD56+ NK cell level could be a useful marker for predicting successful treatment outcome of low-dose IVIg infusion.

N/A Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.

Objective s: Chromosome aneuploidy is associated with recurrent abortion and congenital anomaly and genetic diseases occur repeatedly in the specific families. Preimplantation genetic diagnosis (PGD) can prevent aneuploidy or genetic disease by selecting normal embryos before implantation and is an alternative to prenatal diagnosis. The aim of this study is to assess the outcome of PGD cycles by using FISH or PCR, and to determine the clinical usefulness and values in patients with risk of chromosomal aneuploidy or genetic disease. Materials and Methods: From 1995 to Apr. 2001, a total of 108 PGD cycles in 65 patients with poor reproductive outcome were analyzed. The indications of PGD were translocation (n=49), inversion (n=2), aneuploidy screening (n=7), Duchenne muscular dystrophy (n=5) and spinal muscular atrophy (n=2). PGD was applied due to the history of recurrent abortion, previous birth of affected child or risk of aneuploidy related to sex chromosome aneuploidy or old age. Blastomere biopsy was performed in 6$\sim$10 cell stage embryo after IVF with ICSI. In the single blastomere, chromosome aneuploidy was diagnosed by using FISH and PCR was performed for the diagnosis of exon deletion in DMD or SMA. Results: The FISH or PCR amplification was successful in 94.3% of biopsied blastomeres. The rate of transferable balanced emb ryos was 24.0% in the chromosome translocation and inversion, 57.1% for the DMD and SMA, and 28.8% for the aneuploidy screening. Overall hCG positive rate per transfer was 17.8% (18/101) and clinical pregnancy rate was 13.9% (14/101) (11 term pregnancy, 3 abortion, and 4 biochemical pregnancy). The clinical pregnancy rate of translocation and inversion was 12.9% (11/85) and abortion rate was 27.3% (3/11). In the DMD and SMA, the clinical pregnancy rate was 33.3% (3/9) and all delivered at term. The PGD results were confirmed by amniocentesis and were correct. When the embryos developed to compaction or morula, the pregnancy rate was higher (32%) than that of the cases without compaction (7.2%, p<0.01). Conclusions: PGD by using FISH or PCR is useful to get n ormal pregnancy by reducing spontaneous abortion associated with chromosome aneuploidy in the patients with structural chromosome aberration or risk of aneuploidy and can prevent genetic disease prior to implantation.

목적 : 입원을 요하는 중증 난소과자극증후군 환자에서 난자 채취 시 예방적 알부민 투여가 임상결과에 미치는 영향에 대해서 알아보고자 하였다. 연구 방법 : 1995년 1월부터 2000년 12월까지 삼성제일병원 불임센터에서 체외수정 및 배아 이식술을 시행 받은 환자 중 입원치료를 시행한 중증 난소과자극 증후군 86명을 대상으로 하였으며, 이중 난자 채취시 예방적 정맥내 알부민 주사를 시행한 21명과 시행하지 않은 65명으로 구분하여 그 임상결과를 후향적으로 비교 분석하였다. 결과 : 난소반응을 알 수 있는 여러 지수들 중 배란유도를 위한 hCG투여 당일의 혈중 estradiol (E_2) 농도는 알부민을 투여한 군 (5805.2+1604.4 pg/㎖)이 투여하지 않은 군 (4125.2+1921.5 pg/㎖)에 비해 유의하게 높은 반면 (p<0.05), 임상경과를 알아보는 여러 지수들 (복수천자의 횟수와 양, 입원 후 사용한 알부민의 양, 증상발현기간, 입원기간 등)은 알부민을 사용한 군에서 오히려 낮은 경향을 보였으나 통계적인 차이는 보이지 않았다. 결론 : 본 연구에서 저자들은 중증의 난소과자극증후군이 우려되는 환자에서 난자 채취 당일에 예방적 정맥 내 알부민의 사용이 임상경과를 호전시키는 유용한 방법일 것으로 결론지을 수 있었다. Objective : The purpose of this study is to evaluate the efficacy of prophylactic intravenous albumin in patients with severe ovarian hyperstimulation syndrome (OHSS) who needed hospitalization. Methods : From January, 1995 to December, 2000, 86 women who underwent COH for IVF-ET were hospitalized for the management of severe OHSS in Samsung Cheil hospital. Among them, twenty one patients were treated with prophylactic intravenous albumin at the day of ovum retrieval, and 65 were not. We analysed clinical symptoms, signs, and hospital courses in the records of 86 patients retrospectively. We compared above variables of prophylactic albumin used group (n=21) with those of non-used group (n=65). Results : Among the indices of ovarian response to ovarian stimulation, serum estradiol (E_2) level at the day of hCG injection was significantly higher in prophylactic albumin used group (5805.2±1604.4 pg/ml) than non-used group (4125.2±1921.5 pg/ml, p<0.05). But the variables which indicate clinical progress (number and amount of paracentesis, amount of used albumin after hospitalization, duration of symptoms, hospital days) showed less severe tendency in prophylactic albumin used group but was not significantly different between two groups. Conclusion : Our results indicates that the use of prophylactic intravenous albumin in patients who have risk of severe OHSS had some advantages in favorable clinical progress.
