Objectives: Bok, Bcl-2-related ovarian killer, is a proapoptotic Bcl-2 family protein identified in the ovary based on its dimerization with the antiapoptotic protein Mcl-1. The present study examined the hormonal regulation and localization of Bok messenger RNA levels in the mouse ovary during the follicle development. Methods: The animals were implanted subcutaneously with Silastic brand capsules containing the synthetic estrogen, DES at $21{\sim}23$ days of age. Ovaries were collected $1{\sim}3$ days after implantation for RNA analysis and in situ hybridization. Some mice were removed capsule for $1{\sim}2$ days to induce ovarian follicle apoptosis. Ovaries were also collected from 26 day-old immature mice at various times after treatment with 10 IU PMSG. Some mice received a single intraperitoneal injection of 10 IU hCG to induce ovulation, and ovaries were obtained at different time intervals for Northern blot and in situ hybridization analysis, respectively. Results: Treatment of immature mice with diethylstilbestrol (DES) for $24{\sim}48$ h increased ovarian Bok mRNA levels. Bok mRNA was remained the same levels in mice removed DES for $24{\sim}48$ h to induce apoptosis. High signals of Bok mRNA after DES treatment were detected in granulosa cells of early antral follicles. Treatment of immature mice with PMSG for 12 h increased markedly ovarian Bok mRNA expression which was detected mainly in preantral and atretic follicles. Interestingly, low levels of Bok mRNA were also expressed in granulosa cells of preovulatory follicles. Treatment of PMSGprimed mice with hCG stimulated strongly ovarian Bok mRNA expression at $6{\sim}9$ h. At that time, Bok mRNA was expressed in granulosa cells of atretic and small growing follicles. Conclusion: These results demonstrate that Bok is one of proapoptotic Bcl-2 members expressed in early growing and atretic follicles during the ovarian follicular development. Gonadotropins induce a transient increase of Bok gene expression in granulosa cells of preantral and preovulatory follicles indicating some role in the ovulatory process.

This study was carried to determine the possibility of finding motile spermatozoa and fertilization, pregnancy rate after testicular sperm extraction(TESE) with ICSI in obstructive and non-obstructive azoospermic patients. In 154 cases(132 patients), obstructive azoospermia was 77 cases and non-obstructive azoospermia was 77 cases. In obstructive azoospermia, patients generally showed normal spermatogenesis and included vas agenesis(n=8), multiple vas obstruction(n=7), epididymal obstruction (n=54). Total of 982 retrieved oocytes were obtained and 84.4% were injected. The fertilization rates with 2 PN and cleavage rate were 72.5% and 62.3%, respectively. 30 pregnancies(38.9%) were achieved and the ongoing pregnancies were 22 cases (28.6%). In non-obstructive azoospermia, patients showed hypospermatogenesis(n=49), maturation arrest(n=4), Sertoli cell only syndrome (n=24). The various stages of spermatogenic cell could be retrieved by TESE and could be reached normal fertilization and embryo development with ICSI. Total of 1072 retrieved oocytes obtained and 80.2% were injected. The fertilization rates with 2 PN and cleavage rate were 52.8% and 68.9%, respectively. 22 pregnancies(30.1%) were achieved and the ongoing pregnancies were 19 cases(26.0%). Conclusively, the combination of TESE with ICSI using testicular spermatozoa can achieve normal fertilization and pregnancy rate and effective method in obstructive and non-obstructive azoospermic patients.

Premature rupture of membrane is the most frequent cause of low birth weight infant delivery which increase the maternal and fetal morbidity and perinatal mortality. A retrospective case-control study was performed on 315 mothers who delivered low birth weight infants($\leq$2.5kg) with premature rupture of membrane and as control group 546 mothers who delivered normal birth weight infants(2.9-3.7kg) without premature rupture of membrane were chosen. The results obtained from this study were as follows: 1. The proportion of low birth weight infants due to premature rupture of membrane among all low birth weight infant deliveries was 14.5%, and this is equivalent to 1.1% among all deliveries. 2. The most significant maternal risk factor of low birth weight infant deliveries with premature rupture of membrane was infections on vagina, cervix and uterus during pregnancy. Compared with control, adjusted odds ratio was 7.61(95% confidence interval(CI) 1.88-30.88, p=0.004). Other significant maternal risk factors were the history of induced abortion, spontaneous abortion, and the experience of premature delivery. The risk ratios were 1.82, 2.07, 4.42, respectively. 3. Breech presentation did increase the risk of low birth weight infant delivery with premature rupture of membrane compared with control(Adjusted Odds ratio=2.66, 95% CI 1.35-5.26, p=0.005). 4. Mothers who had not taken antenatal care were having higher risk of low birth weight infant delivery with premature rupture of membrane against control(Adjusted odds ratio=1.73, 95% CI 1.19-2.53, p=0.004). These study results show that maternal factors such as the infection of genital organs during pregnancy, the history of induced abortion and breech presentation are significantly associated with the premature rupture of membrane in the low birth weight deliveries, and that most of these risk factors are controllable ones through proper antenatal cares.

The present study was conducted to measure health-related utility for post-menopausal symptoms among Korean woman. A survey questionnaire was developed to measure utility based on visual analogue scale(VAS) and time trade-off method (TTO). From January 29 to February 3, 2007, a face-to-face interview was conducted with 274 women aged 45 to 60 to ask about their subjective utility for hypothetical health status of mild or severe post-menopausal symptoms. Among the participants, 160 were recruited from outpatient departments of 3 hospitals and 114 from 2 sports centers located in Seoul. For mild symptom, the average utility score of the respondents was $0.63{\pm}0.14$ based on VAS and $0.61{\pm}0.26$ based on ITO. For severe symptoms, the average utility was $0.39{\pm}0.16$(VAS) and $0.44{\pm}0.27$ (TTO). For severe symptom, a higher utility score was observed for TTO than for VAS, which is consistent with earlier studies and thus supports the validity of the utility measurement in this study. Overall, the severity of post-menopausal symptoms of the respondents themselves was not significantly associated with the utility score that the respondents answered for hypothetical health status. Multiple regression analysis results showed that the utility score was significantly higher among respondents with older age, higher education, higher family income, and from hospitals. It is expected that the utility score measured in this study will enhance the understanding of the quality of life of women after menopause and will be used to conduct cost-utility analysis of health care interventions to treat post-menopausal symptoms.

Objectives: Pelvic tuberculosis (TB) causes infertility despite of anti-TB chemotherapy and IVF-ET is effective treatment to achieve pregnancy. The aim of this study is to assess the outcomes of IVF-ET in pelvic TB, especially according to main Tb lesion, and to investigate the factors affecting the successful outcome. Methods: A total of 135 IVF-ET cycles were performed in 54 patients with pelvic TB and the outcome was compared with that of control group with tubal factor not associated with TB in 301 cycles, 227 patients. Anti-TB chemotherapy was performed in the patients with pelvic TB. Pregnancy rate was compared according to main TB lesion as salpingitis, peritonitis, and endometritis. In the patients with endometrial TB, when complicated with uterine synechia, hysteroscopic lysis was done before IVF-ET and pregnancy rate was compared according to the presence of uterine synechia. Results: There was no significant difference in peak E2 ($2,790{\pm}280.1$ vs $2,554{\pm}101.2$, p>0.05), the number of retrieved oocytes ($13.5{\pm}0.7$ vs $12.5{\pm}0.4$, p>0.05) and fertilized oocytes ($7.7{\pm}0.5$ vs $7.8{\pm}0.3$, p>0.05) between patient and control group. Clinical pregnancy rate per transfer in pelvic TB group was 22.9% and showed no difference from that of control group (24.3%, p>0.05). Although it was not statistically significant, pregnancy rate in the endometrial Tb (18%) was lower than that in the salpingitis (28.5%) or peritonitis (26.5%) (p>0.05). In the endometrial TB with uterine synechia, pregnancy rate was significantly lower than that of the patients without synechia even after hysteroscopic lysis (9.7% vs 31.6%, p<0.05). Conclusion: IVF-ET after anti-TB chemotherapy is the most effective treatment to achieve pregnancy in infertile patients with pelvic TB. Because the presence of endometrial TB and resulting uterine synechia affects the outcome of IVF-ET, thorough evaluation for endometrium with endometrial biopsy and hysteroscopy is important to predict the prognosis of IVF-ET treatment.

Objective: Ovarian angiogenesis plays an important role in folliculogenesis. However, little is known about the expression of angiogenic factors during follicular development according to female age. Stromal cell derived factor-$1{\alpha}$ (SDF-$1{\alpha}$) plays a role in granulosa cell survival and embryo quality as an angiogenic chemokine. Leptin is also involved in folliculogenesis and angiogenesis. This study examined expression of SDF-$1{\alpha}$ and leptin, and their effects on the expression of angiogenic factors in the ovary during follicular development according to female age. Methods: Ovaries were collected from C57BL mice of two age groups (6-9 weeks and 24-26 weeks) at 6, 12, 24, and 48 hours after 5 IU pregnant mare's serum gonadotropin (PMSG) injection. The expression of ovarian SDF-$1{\alpha}$ and leptin mRNA was evaluated by RT-PCR. In the organ culture experiment, the ovaries were cultured in transwell permeable supports with Waymouth's medium treated with various doses of SDF-$1{\alpha}$(50-200 ng/mL) or leptin (0.01-1 ${\mu}g$/mL) for 7 days. Then, mRNA expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), and visfatin were examined in the cultured ovaries. Results: Expression of SDF-$1{\alpha}$ and leptin in the ovary was significantly lower in the aged mouse group compared to the young mouse group ($p$ <0.05). Expression of these two factors increased with follicular development after PMSG administration. SDF-$1{\alpha}$ treatment stimulated visfatin expression in a dose-dependent manner, while leptin treatment significantly increased eNOS expression. Conclusion: These results suggest that decrease of ovarian SDF-$1{\alpha}$ and leptin expression may be associated with aging-related reduction of ovarian function. SDF-$1{\alpha}$ and leptin may play a role in follicular development by regulating the expression of angiogenic factors in mouse ovaries.

Objectives: This study was a methodological study to verify the reliability and validity and to make a diagnosis of a diagnostic tool for climacteric and postmenopausal syndrome pattern identification (CaPSPI). Methods: This study was conducted from June 1, 2018 to October 18, 2018 with ${{\bigcirc}{\bigcirc}}$ University Korean Medicine Hospital IRB's approval (2018-3). To make a diagnosis using CaPSPI, we decided the cut-points for the tool. Three professors of ${{\bigcirc}{\bigcirc}}$Korean Medical University conducted pattern identification diagnosis. The result is marked from 0 to 3, 0 is 'No', 1 is 'Slightly Yes', 2 is 'Yes' and 3 is 'Very Yes'. And if two or more professors' diagnoses are the same, we took the diagnoses as a diagnostic criteria. The decision of pattern by three experts converted to 0-1 scores in two ways. In "method 1", if the diagnosis was zero points, the score was 0 (have no such identification), and the rest was 1 (have such identification). In "method 2", if the diagnosis was zero or 1 point, the score was 0, and the rest was 1. After that, intraclass correlation was calculated for experts agreement. And logistic regression was conducted. A response variable was the results of the experts' diagnosis and an explanatory variable was the results of the pattern identification diagnostic tool. Results: The diagnosis of the three experts showed excellent concordance of more than 0.794 and showed a significant correlation with the diagnostic tool. Both 'Method 1' and 'Method 2' showed statistically significant effects with the diagnosis of 3 experts and the results of the diagnostic tool. The frequency of cumulative pattern identification diagnosis in 'Method 1' and 'Method 2' were found to be 578 occasions and 203 occasions, respectively. The average number of pattern held by participants in 'Method 1' and 'Method 2' were found to be 5.26 and 1.85, respectively. In both "Method 1" and "Method 2," the yield frequency of liver qi depression was the highest, and the frequency of kidney yin deficiency and liver-kidney yin deficiency was relatively high. Conclusions: Based on the above results, it is thought that, in diagnosis using CaPSPI of menopausal women, 'method 1' could be used for the health diagnosis and prevention, 'method 2' could be used for the pattern diagnosis. On the conclusion, CaPSPI is thought to be available for pattern diagnosis of menopause women.
