This study was performed to investigate the stimulating effect on oocyte maturation and cumulus cell expansion in TC199 media by human cord serum (HCS) supplementation. Immature mouse oocyte cumulus complexes (OCCs) were cultured in TC199 media supplemented with bovine serum albumin (BSA), HCS and human chorionic gonadotropin (hCG) instead of luteinizing hormone (LH) respectively, and the expression of cumulus expansion and oocyte maturation were observed. After 4hr and 24hr culture with or without OCCs, media containing 0.4% BSA, 10% HCS and 10 lU hCG respectively were collected and analyzed for changing concentrations of estradiol (E2), progesterone(P4), testosterone(T), and PGF2. There were no elevation of E2, T, and PGF2 by OCCs culture, but minute elevation of P4 level by 24hr OCCs culture in hCG supplementation (p=0.048). The stimulating pattern of cumulus expansion of OCCs by HCS and hCG supplementation was similar to our previously report using Ham's F-10 media, however oocyte maturation rates after 24hr OCCs culture in all media were increased by 20~30% compared to Ham's F-10 media. These results suggest that LH in HCS induce cumulus expansion probably by P4 secretion of OCCs, and TC199 is efficient media for immature mouse oocyte maturation.

2.A Clinical Study of 12 Cases of Sarcoma of the Uterus.
Korean Journal of Gynecologic Oncology and Colposcopy 2000;11(4):404-410
OBJECTIVE: Sarcoma of uterus is originated from uterine muscles and/or connective tissues and rare and most lethal of all primary uterine tumors. The purpose of this study was to evaluate the clinical outcome of 12 patients diagnosed primary uterine sarcoma at the Department of Obstetrics and Gynecology in Kyungpook National University Hospital between 1984 and 1998 for 15 years. METHODS: After review of chart in twelve patients, data including clinical and histologic findings, treatment and outcome were analysed. RESULTS: The most common histologic finding was leiomyosarcoma(6cases, 50%) and the age of patients ranged 24 to 69 years and the average age was 43.25 years and two patients were nulliparous. The most common sign was abnormal uterine or vaginal bleeding(48%), and pelvic cavity or vaginal mass(16%), pelvic pain(16%), no symptom(16%), in order of frequency. The distribution by FIGO clinical stage was four cases(33%) for stage I, one case (8%) for stageII, one case(8%) for stage III, six cases (50%) for stage N. The nine cases received hysterectomy with or without BSO. Two cases received myomectomy to preserve fertility. The mean follow-up duration was 39.6 months. CONCLUSION: Uterine sarcoma is an uncommon and aggressive tumors with a poor prognosis. Leiomyosarcoma is the most frequent histologic type(50%). Stage I uterine sarcoma with or without adjuvant chemotherapy has better prognosis than other stages.

3.Two Cases of Congenital Ectodermal Defect.
Korean Journal of Dermatology 1968;6(1):45-49
Tow cases of congenital ectodermal defect in brothers aged 15 and 10 years were pesinted and the literature was reviewed. They had lack of sweating, sparseness of the hard hairs, absence of lanugo hairs, maldevelopment or defect of most of the teeth, etc. They seemed to be angidrotic type associated with a sex-linked reccessive inheritance in their family backgroud.

OBJECTIVE: To estimate the predictive value of initial serum B-hCG and progesterone measurement for pregnancy outcome in IVF-ET. METHODS: Serum B-hCG at 11-12th day after embryo transfer and progesterone at 7th day after oocyte aspiration were measured in 48 successful pregnant IVF-ET cases from July 1993 to June 1997. RESULTS: Of 48 cases, 26 cases (54.2%) successfully carried to sustaining gestation and 22 cases (45.8%) failed to sustain gestation. The estimated initial serum B-hCG levels in the normal sustaining pregnancy group (132.28+ 22.42 mlU/ml) were statistical significantly higher than 29.43+8.08 mIU/ml in the failed sustaining pregnancy group (p<0.001), while the estimated initial serum progesterone levels showed no significant differences (p=0.159). In order to determine the predictive values using the Receiver Operator Curve (ROC), an appropriate cutoff value of 38 mIU/ml for initial serum B-hCG was obtained. In IVF-ET pregnancies, the estimated serum B-hCG levels in cases of chemical abortion in failed sustaining pregnancy were significantly lower compared to the normal sustaining pregnancy group (p<0.001). CONCLUSION: The initial serum B-hCG levels at 11 days after embryo transfer could be used to predict the pregnancy outcome in an IVF program. An initial progesterone level acquired on the 7th day after oocyte retrieval is not a useful indicator to predict pregnancy outcome.

OBJECTIVES: This study was to investigate the fertilization rate after intracytoplasmic sperm injection (ICSI) or partial zona dissection (PZD) of human and hamster sperm into hamster oocyte in in vitro fertilization (IVF). In addition, the possibility of clinical application was evaluated by the comparison of usefulness and difference of these method. MATERIALS AND METHODS: Hamster immature oocytes were obtained from oviducts superovulated by PMSG and hCG, and hamster sperms were obtained from epididymis. The freezed human sperms were thawed before use. Fertilization were confirmed by two pronuclei, one pronucleus, swollen sperm head or/and two polar bodies at 7~8 hour after ICSI or PZD. RESULTS: The fertilization rates after ICSI and PZD of human sperm to hamster oocyte were 3.6%, 64.2%, 73.6%, and 55.6% for negative control, positive control, ICSI, and PZD respectively, suggesting that ICSI only showed improved fertilization rate (p<0.01). The fertilization rates after ICSI and PZD of hamster sperm to hamster oocyte were 11.1%, 51.2%, 39.6%, and 72.7% for negative control, positive control, ICSI, and PZD respectively, suggesting that PZD only showed improved fertilization rate (p<0.01). PZD showed significantly higher fertilization rate than ICSI (p<0.05). CONCLUSIONS: As for the fertilization rate by ICSI and PZD using hamster oocyte in IVF, ICSI technique was considered to be more useful for human sperm and PZD technique for hamster sperm. Therefore, ICSI technique was considered more appropriate for experimental application using human sperm and hamster oocyte.
