OBJECTIVE: To verify the effect of Matrigel, a ECM complex from Engelbreth-Holm-Swarm(EHS) mouse sarcoma on the preimplantation development and apoptosis of mouse fertilized eggs. METHOD: Late Pronucleus stage eggs were cultured through the blastocyst stage in the presence of Matrigel (0.5%, v/v). Characteristics of apoptosis and cell number assessed by Hoecst staining and TUNEL labeling at the blastocyst stage, respectively. RESULTS: Morphological development, number of cells per embryo was significantly increased but rate and number of TUNEL positive nuclei of the embryo were decreased in the presence of Matrigel. CONCLUSION: This result suggested that at low concentration of Matrigel improves both viability and morphological development in the preimplantation mouse embryos.

Endovascular aneurysm repair (EVAR) for the treatment of abdominal aortic aneurysm (AAA) is a widely used method, and its decreased invasiveness compared to traditional surgical repair has brought about reduced rates of morbidity and mortality. Several vascular complications related to the procedure have been reported, but non-vascular complications have rarely occurred. We report herein the case of a 78-year-old man who underwent EVAR for AAA and presented with active duodenal ulcer bleeding and acute acalculous cholecystitis as complications after the procedure. We must consider that a wide spectrum of complications may occur following EVAR, and therefore it is important to evaluate the risks of complication and to take the necessary measures to minimize them.

OBJECTIVES: To determine whether the body weight, body mass index (BMI), and basal serum level of LH, FSH, testosterone (T), dehydroepiandrosterone sulfate (DHEA-S) are related to the ovarian response to clomiphene citrate (CC) in patients with polycystic ovarian syndrome (PCOS). MATERIALS AND METHOD: From January 1996 to June 1997, total 57 patients with PCOS were enrolled in the present study. Women who had other infertility factors were excluded from our study. The ovulation induction using CC was used in all patients. The patients were grouped into 50 mg group, 100 mg group, and 150 mg group according to their daily CC dose. The patients were also grouped to ovulatory and non-ovulatory group. The body weight, BMI, arid basal serum level of LH, FSH, T, DHEA-S were measured in all patients on the 2nd or 3rd day of the menstrual cycle. Results were analysed with Student's t-test and Fisher's exact test. RESULTS: The body weight and BMI of the nonovulating group were significantly higher than those of the ovulating group in all groups (50, 100, 150 mg of CC). However, there were no significant differences of the level of LH and FSH between ovulating and nonovulating groups in all CC groups (50, 100, 150 mg). The level of T of nonovulating group was significantly higher in 50 and 100 mg of CC groups, but not in 150 mg group. The level of DHEA-S of the non-ovulating group is significantly higher in 50 mg group, but not in 100 and 150 mg groups. CONCLUSION: The body weight and BMI could be useful predictors of ovarian response to CC in patients with PCOS, and basal T and DHEA-S also might be useful in cases of low-dose CC treatment.

Changes of bone turnover with aging are responsible for bone loss and play a major role in osteoporosis. Among the early postmenopausal women, as are known by previous study, there are about 35% ""fast bone losers and bone turnover is more uncoupled in osteoporotic group than in normal control. So, early detection of such fast losers"" and women who have high turnover rate is important to prevent postmenopausal osteoporosis and spontaneous fracture. Dual-energy X-Ray absorptiometry (DEXA), however, cannot reflect current bone loss because changes in bone mineral density (BMD) are only seen after 1 or more years of bone densities declining. In this study, we have measured a battery of new sensitive and specific markers of bone turnover which reflect current bone loss. To investigate the changing pattern of those markers, 674 healthy women including 451 postmenopausal women were classified, according to their menopausal period (less than 5 years, 5-10 years, more than 10 years). Bone formation was assessed by serum osteocalcin (OC), bone-specific alkaline phosphatase (BSAP) and bone resorption by the urinary excretion of deoxypyridinoline (DPD), cross-linked N-telopeptide of type I collagen (NTX). All Biochemical markers, except OC, significantly increased after menopause (p < 0.05). NTX and BSAP remained elevated after 10 years of menopause. These data indicated that the overall rates of both bone formation and bone tesorption increased after menopause and remained high in elderly women.

It is well known that the clinical test for responsibility of accurate fertilization capacity in male partners is very important to diagnose and treat the infertility. However, it has been reported that the traditional semen analysis cannot accurately predict fertilization and pregnancy potential. The present study was performed to evaluate the acrosomal reaction to ionophore challenge (ARIC) test as a prognostic indicator for fertilization of sperm and oocyte in an in vitro fertilization and embryo transfer (IVF-ET) program. From March 1996 to Februry 1997, 30 couples undergoing IVF program were allocated to this study group. All female partners in the study group were 35 years old or less and their serum level of basal follicle stimulating hormone (FSH) and estradiol (E2) were normal. All the male partners have normal parameters of semen analysis. The ARIC tests were performed on the day of ovum pick up and in vitro insemination in all the male partners. The controlled ovarian hyperstimulation (COH) using luteal long protocol of gonadotropin releasing hormone (GnRH) agonist was used in all couples for IVF-ET. The acrosomal reaction with 10microliter of 10% DMSO was induced spontaneously in 10.1+/-9.8%, and acrosomal reaction with calcium ionophore A 23187 was induced in 27.4+/-18.1%, and the ARIC value was 17.4+/-16.2%. There were no significant correlation between the ARIC value and the fertilization rate (r2=0.044, p=0.268). There were also no significant correlation between the ARIC value and the percentage of the grade I, II embryos (r2=0.046, p=0.261). On the basis of above results, it was suggested that ARIC test might not be a useful prognostic indicator for fertilization in IVF-ET in male partners with normal parameters of conventional semen analysis. We guessed that IVF-ET could be performed to the patients primarily without universal appilcation of ARIC test to all male partenrs, and if fertilization failure occurs, the microassisted fertilization (MAF) such as intracytoplsmic sperm injection (ICSI) might be used as an alternative mode of treatment with acceptable success rate.

OBJECTIVES: To investigate the patterns of biochemical bone markers, such as urinary deoxypyridinoline (DPD), N-telopeptide of type I collagen (NTX), and serum osteocalcin (OC), bone-specific alkaline pbosphatase (BSAP) in postmenopansal women with hormone replacement therapy (HRT). Materials and METHOD: From July 1997 to January 1998, total 239 postmenopausal women were emolled in the present study, and 198 healthy premenopausal women with regular menstruation were served as control. The postmenopausal women were pouped into the HRT group and the non-HRT group. The women in the HRT poup have received estrogen with continuous or cyclic progestin therapy far more tban 6 months. The biochemical bone markers of all women were assayed. Results were analysed with Students t-test. RESULTS: The urinary DPD of the non-HRT group was sigaificantly higher than both the HRT poup and the premenopausal group(5.51 +/- 2.47 vs. 3.36 +/- 1.02 and 4.01 +/- 3.86 nM/mM, p < 0.05, repectively). The urinary NTX of the non-HRT group was also higher in comparison to the HRT group and the premenopausal group(48.71 +/- 11.54 vs. 33.70 +/- 17.43 and 33.70 +/- 17.43 nM BCE/mmol, p < 0.05, repectively). However, there were no significant differences in the concentrations of serum BSAP and OC among the three poups. CONCLUSION: The urinary DPD and NTX were more sensitive indicators of bone metabolism tban serum BSAP and OC in postmenopausal women undergoing HRT.

OBJECTIVE: To determine if basal serom follicle stimulating harmone (FSH) level could be a prognostic factor of the clinical outcome in in vitro fertilization and embryo transfer (IVF-ET) with intracytoplasmic sperm injection (ICSI) in the couples with male factor infertility. Materials and METHOD: From December 1995 to March 1998, total 118 patients with male factor infertility were included in this study. Patients were allocated to the low basal FSH group (>8.5 mIU/ml) and the high basal FSH group (>8.5 mlU/ml). The basal levels of FSH were measured in the 3rd day of menstrual cycle preceding ovarian stimulation cycle in total IVF cycles by immunoradiometric assay (IRMA). Statistical analysis was performed using Student's t-test, Fishers exact test, and x2 test as appropriate. Statistical significance was defined as p < 0.05. RESULTS: The total dose of exogeneous gonadotropin required in the patients of the high basal FSH group was significantly higher than that of the patients with the low basal FSH poup (p < 0.05). The numbers of retrieved oocytes, oocytes with grade I, II, fertilized oocytes, cleaved oocytes, embryos with grade I, II, and transferred embryos were significantly higher in the low basal FSH group (p < 0.05), The clinical pregnancy rate per cycle in the low basal FSH gmup (15.7%) seemed to be higher than that in the high basal FSH poup (3.4%) (p 0.08), however, there was no statistically significant difference between the two groups. CONCLUSION: These results suggested that the basal FSH levels could be predictive of pregnancy outcome and the results of ovarian stimulation in IVF-ET using ICSL.

With the advent of intracytoplasmic sperm injection (ICSI), the fertiliution and pregnancy have been reported even in complete asthenozoospermia. However, the results of ICSI in men with totally immotile sperm was still disappointing. The reasons for the total lack of sperm movement are not yet determined. The immotility of ejaculated spermatozoa is probably caused by sperm degeneration during epididymal transport, therefore higher viable spermatozoa can be obtained by testicular sperm recovery in some cases with low viability and total lack of movement of ejaculated spermatozoa. Recourse to testicular spermatozoa for ICSI is thus an alternative treatment possibility in this kind of pathology. This clinical study was performed to investigate the efficacy of ICSI employing testicular and ejaculated spermatozoa. From December 1995 to March 1998, 35 couples with totally immotile spermatozoa were included in the study. In 14 patients, the ejaculated spermatozoa were used whereas in 21 patients the spermatozoa were recovered from the testis. There were no significant differences in the fertilization and cleavage rates between the testicular sperm group with 62.6%, 52.7% and the ejaculated sperm group with 56.1%, 74.3%. Two pregnancies were achieved, one in the testicular spnm poup and the other in the ejaculated group. A healthy child was delivered at term in the ejaculated sperm group, but a clinical abortion occurred in a pregnancy in the testicular sperm group. In conclusion, it was suggested that ICSI using ejaculated sperm might be a primary treatment in cases with totally immotile spermatozoa and, if failed, testicular sperm could be used as an alternative mode of heatment.

The effects of embryo number and incubation volume on the development of mouse embryos were evaluated. The growth rate of two-cell mouse embryos to attached blastocyst stage and the growth rate of blastocysts to early somite stage were assessed after culture in different incubation volumes and embryo densities. Embryos were collected from ICR female mice superovulated with pregnant mare serum gonadotropin and human chorionic gonadotropin and mated by ICR males. In experiment 1, groups of one, five, ten, twenty 2-cell embryos were cultured in 10-, 50-, 500-, 1000-microliter drops of BWW media under mineral oil at 37 degrees C in a humidified atmosphere of 5% CO2 and 95% air. As the incubation volume decreased, significantly (p<0.05) higher rates of embryos reached morular and blastocyst stage on day 3 and 4 culture, respectively In experiment 2, groups of one, five, ten, twenty blastocysts were cultured in 1- and 2-ml volumes of CMRL 1066 media under same condition as in experiment 1. However the reverse was the result. Decreasing the number of embryos incubated per volume from 1 to 20 significantly (p<0.05) increased the number of blastocysts reaching the late egg cylinde. (LEC) and early somite (ES) stage on day 6 and 8 culture, respectively, regardless of incubation volume. Blastocysts cultured in 2ml had higher (p<0.05) development rates to LEC and ES stage on day 6 and 8 culture, respectively, than embryos cultured in 1ml. Our results suggest that the effects of embryo number and incubation volume on the development of mouse embryos are stage specific and the shifting point was between hatching and EEC stage.

It was reported that the etiologies of recurrent spontaneous abortion are immunologic factors, endocrinologic problems, anatomical abnormalities, genetic abnormalities, infection, and unexplained factors. Among those etiologic factors, genetic abnormalities occur in about 5% of the couples who experience recurrent spontaneous abortions, and most common parental chromosomal abnormality contributing to recurrent abortion is balanced translocation. The advent of in vitro fertilization (IVF), the development of skills associated with the handling of human embryo, and an explosion of knowledge in molecular biology have opened the possibility of early diagnosis of genetic disease in preimplantation embryos. Therefore preimplantation genetic diagnosis (PGD) is indicated for couples, infertile or not, at risk of transmitting a genetic disease. A case of successful pregnancy and term delivery by PGD using fluorescence in situ hybridization (FISH) technique in patient with recurrent spontaneous abortion due to balanced translocation is presented with brief review of literatures.
