The athors have presented recently treated 4 cases of malignant tumors of the eye and adnexa. 1. All of them were rapidly aggrevated after previous incompleted surgical management (3 cases) or postponement 01 operation (1 case). 2. Three cases of them except adenoid cystic Ca. were recurred after orbital exenteration. 3. The authors were concluded that the poor prognosis is due to its nature of malignancy and delayed radical surgical management.

The authors observed clinically typical case of unilateral coloboma of the optic disc. This patient, 5 years old Korean boy, visited to our clinic with the chief complaints of visual disturbance and intermittant exotropia of left defecting eye. The optic disc was enlarged about 2.5 times of normal optic disc diameter excavated about 7.0 Diopters in depth. The vision of colombomatous left eye was 20/50(n.c.) but the cause of defective vision was not evaluated certainely whether it might be due to coloboma itself or slight posterior subcapsular opacity of the lens.

Extracorporeal shock wave lithotripsy(ESWL) for urinary calculi is usually performed under general anesthesia, regional anesthesia or intravenous anesthesia. We evaluated the sedativeanalgesic effeet and untoward effects of diazepam-fentanyl for ESWL. 60 patients were belonged to physical status 1 or 11 of ASA classification who injected diazepam(5~10 mg) and fentanyl(1.5 ug/kg) at 2 minutes were as follows The results were as follows; 1) Mean arterial pressure(MAP) was significantly decreased in 3-10 minutes after injection compared to baseline value. 2) Heart rate(HR) was statistically nonsignificant but slightly decreased from 2 minutes after injection. 3) Respiratory rate(RR) and arterial oxygen saturation(SaO2) were significantly decreased until 15 miuntes after injection but SaO was not decreased below 92.7% and RR was not decreased below 13 rates/minute. 4) Pain and movement during ESWL developed in 18 cases but repositioning and discon- tinuation of EWSL were not necessary. Episodes of desaturation(SaO2<90%) developed in 2 cases. 5) Postoperative dizziness developed in 24 cases. nausea and vomiting developed in a few cases. We concluded that intravenous administration of diazepam-fentanyl is more convenient and simpler than other anesthetic technique for ESWL.

OBJECTIVE: To analyze the efficacy of intracytoplasmic sperm injection (ICSI) for totally unfertilized oocytes by the conventional insemination during in vitro fertilization and embryo transfer (IVF-ET) METHODS: From March 1996 to April 1998, 15 couples who experienced total fertilization failure after conventional IVF without severe male factor infertility in semen analysis were evaluated. Fertilization were assessed by the presence of 2 pronucleus (PN) after 14-16 hours of conventional insemination. All unfertilized oocytes were reinseminated by ICSI and checked for signs of fertilization between 6-10 hours after ICSI. The embryos with fertilization and development were transferred to the uterine cavity and the outcome was analyzed. RESULTS: Total numbers of unfertilized oocytes were 120, and total numbers of oocytes injected on day 1 using ICSI were 102. Total numbers of oocytes with normal fertilization after ICSI were 74 and mean fertilization rate of 71.1 +/- 24.0% was obtained. The numbers of embryos transferred was 3.6 +/- 1.7. The biochemical pregnancy rate was 13.3% (2/15) and the clinical pregnancy rate was 6.7% (1/15) per cycle. CONCLUSION: ICSI to totally unfertilized oocytes by conventional insemination technique during IVF-ET on the next day of oocyte retrieval seems to be a relatively successful mean and afford a chance of pregnancy to the infertile couples whom the ET could not perfomed to because of total fertilization failure."

OBJECTIVE: To determine whether the somatostatin analogue, octreotide, given concunently with human menopausal gonadotropin (HMG) affects ovarian response, ovulation induction outcome, and serum levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) in infertile patients with polycystic ovarian syndrome (PCOS) resistant to clomiphene citrate (CC). METHODS: From August 1996 to June 1998, 42 infertile patients with PCOS urresponsive to CC were enrolled in the present study. Women who had other infertility factors were excluded from this study. Patients were randomly allocated either to combined HMG and octreotide treatment (treatment group) (n=21) or HMG alone (control group) (n=21). In the treatment group, 100 micrograms of octreotide were administered daily concomitantly with HMG from the 3rd day of menstrual cycle to the preceding day of human chorionic gonadotropin (HCG) injection. RESULTS: Patient's characteristics were comparable in both groups. One cycle in the control group was abandoned because of excessive follicular development. However, none of the cycles in the treatment group was abandoned. There were no differences in the number of HMG ampules required and the duration of HMG administration between the two groups. The number of follicles > 14mm diameter on the day of HCG injection was significantly less in the treatment group than that in the control group (p<0.01). The serum estradiol level on the day of HCG injection was also significantly lower in the treatment group, with 1391.0 +/- 695.5 pg/ml compared with 2217.5 +/- 811.6pg/ml in the control group (p<0.001). The incidence of severe ovarian hyperstimulation syndrome seemed to be lower in the treatment group, but the difference did not achieve significance (4.9% vs 23.8%). There were no differences in the clinical pregnancy rate, miscarriage rate and multiple pregnancy rate between the two groups. Although serum GH levels were comparable between the two groups, serum IGF-1 level on the day of HCG injection was significantly higher in the treatment gmup than that in the control group (p<0.001). CONCLUSION: This study suggests that the combined octreotide and HMG treatment could improve hormonal milieu and folliculogenesis compared to HMG alone, and therefore may be effective in ovulation induction for patients with PCOS resistant to CC.

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.

BACKGROUND/AIMS: The most effective method of improving survival in patients with HCC is early diagnosis and curative hepatic resection. However, longterm survival after curative resection remains low because of high recurrence rate after resection. The purpose of the study is to assess the prognosis and the efficacy of the various treatment modalities on recurrent HCC after curative resection. METHODS: The clinical records of 50 patients with recurrent HCC were reviewed retrospectively who underwent curative surgery in Yonsei University, Severance Hospital from Jan. 1987 through Oct. 1994. The cummulative recurrent rate after resection, the response rate of treatment after resection, the median progression free survival and the survival after recurrence according to the treatment modalities were evaluated. RESULTS: The cummulative recurrent rate after resection was 3.9% at 3 month, 8.3% at 6 month, 14.1% at 12 month, 21.5% at 24 month, 23.4% at 36 month and 24.4% at 60 month. The response rate of treatment after recurrence was 23.7% (9 patients). The median progression free survival of the patient with reoperation and hepatic embolization was 13.9 months, that of conservative treatment group was 6.8 months and that of no treatment group was 4 months(p = 0.004). The survival after recurrence of HCC was 19.7 months in reoperation and hepatic embolization group, 11.4 months in multimodality group, 16.9 months in conservative treatment group and 8.4 months in no treatment group(p=0.0998). CONCLUSION: Reoperation and hepatic embolization for HCC after curative resection was effective in improving progression free survival, but overall survival were not significantly different according to the treatment modalities. This results proposed that reoperation and hepatic embolization for recurrent HCC after curative resection improve progression free survival.

Since the blastocyst is broken and spreads out on a flat plastic culture dish (two dimensional culture) during in vitro development, it has been difficult to study the implantation process. It also has been difficult to analyse the interactions between endometrial epithelial and stromal cells because of the lack of a long-term in vitro model which can stimulate in vivo characteristics, as these cells eventually fail to proliferate or cease to express differentiated functions. Recently nontransformed cell lines, CUE-P and CUS-V2, derived from rat endometrial epithelium and stroma were reported. In this study, morphology of CUE-P and CUS-V2 was examined and oxytocin gene expression by CUE-P cells was demonstrated by RT-PCR. The CUE-P cells have a cuboidal morphology and CUS-V2 cells resemble fibroblast and exhibit a spindle-like morphology. In RT-PCR, same size of PCR products of oxytocin gene at hypothalamus, uterus and CUE-P cells were demonstrated. These results showed three dimensional culture system could be made by using the new cell lines.
