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.

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."

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.

Congenital diaphragmatic hernia (CDH) is caused by a failure of fusion of the muscular diaphragm and results in herniation of abdominal viscera into the thorax, It occurs in appoximately 1 in 2,200 to 5,000 live births, and most cases are probably multifactorial, but they can be also associated with chromosomal abenation. Due to the improvement of sonography, it can be diagnosed more accurately. However, the mortality associated with CDH is extremely high. It is well known that the incidence of congenital anomaly in infants after in vitro fertilization and embryo transfer (IVF-ET) is not increased copared with that of general population, and CDH that occurred following IVF-ET has not been reported. A case of CDH that occurred following IVF-ET is presented with brief review of literatures.

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: A quantitative, rather than visual, assessment of the outcomes of facial surgery has recently become increasingly important, and this is best accomplished using anthropometry. However, most anthropometric methods have limited applicability in office settings. METHODS: We conducted preliminary studies on images of a 30-cm straight edge ruler with various camera-to-object distances (OD) and aperture sizes, and identified a convenient range of ODs and the most reliable aperture size of our camera for photogrammetry. Subsequently, we measured various lengths circumjacent to the center of the ruler in the images of different ODs with a graphics viewer program and calibrated the raw data using the central 20-mm length. We obtained a reliable circle in our camera's viewfinder from a chart of percentage differences between the calibrated data and coupled real ruler lengths. Following this, we replaced the concept of the central 20-mm length with a geometric sphere 20-mm in diameter, and applied it to clinical photogrammetry. RESULTS: The percentage differences were almost directly proportional to the real lengths. This value was below 0.48% in the central 160-mm of all images within an OD range of 50 to 125 cm. In clinical applications, the greatest difference compared to direct measurements was 0.97 mm. CONCLUSIONS: Using a graphics viewer program, we performed anthropometric measurements of images that included a sphere of known size, without printing the images; the difference between these and direct measurements was <1 mm. This method is simple enough for use in an office setting.

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.

Scrub typhus, an acute febrile infectious disease caused by R. tsutsugamushi, has been reported from various parts of the far east and pacific rim of Asia including Korea. It is well known that all human pathogenic rickettsia share an affinity to endothelial cells of the small blood vessels and evoke vascular inflammation variably associated with a rash, microthrombi, and hemorrhage. We infected the ICR mice by inoculating sublethal doses of R. tsutsugamushi R19 strain intraperitoneally and observed the pathologic changes by time sequence. The histopathologic features of experimentally induced scrub typhus in the mice were generally nonspecific interstitial inflammations characterized by interstitial pneumonitis, periportal inflammation, multifocal hepatic necrosis, interstitial nephritis, sinusoidal engorgement, and lymphohistiocytic cell infiltration in lymph nodes and spleen. Contrary to the general features of other rickettsial diseases, the pathologic process of scrub typhus experimentally induced by R. tsutsugamushi R19 strain mainly involved the interstitial connective tissue but not the blood vessels.
