Objective: To determine the reproductive outcomes of women undergoing microsurgical reversal of tubal sterilization at age 36 years or older. Materials and Methods: A series of 133 patients who received microsurgical reversal of the previously sterilized fallopian tubes at Seoul National University Hospital from July, 1980 to January, 1992 was reviewed and evaluated for clinical characteristics, pregnancy rates, and factors influencing the outcome of tubal reversal. Results: Of 133 patients, 78 (58.6%) had been sterilized by laparoscopic cautery. Loss of children was a leading cause for tubal reversal. The mean interval from tubal sterilization to tubal reversal was 65.0 months. The overall pregnancy rate was 52.6% (70/133), and the mean interval was 9.4 months from tubal reversal to pregnancy. Excluding 7 patients who were lost to follow-up, 76 pregnancies were confirmed in 63 patients with the delivery rate per patient of 66.7% (42/63). There were no significant differences in age, duration of tubal sterilization, postoperative tubal length between pregnant and non-pregnant groups. Conclusions: Microsurgical reversal of tubal sterilization could be a justifiable method in women 36 years age or older.

This study was designed to investigate the relationship between insulin resistance and obesity in the pathogenesis of polycystic ovarian syndrome(PCO). Twenty-two women with PCO, of whom thirteen were non-obese with body mass index(BMI, kg/$m^2$) of <25 and nine were obese with BMI${\geq}$25 were studied. Eight non-obese control women and seven obese control women were studied. Serum concentrations of testosterone, lutenizing hormone(LH)/follicle-stimulating hormone(FSH) ratio, and insulin-like growth factor I (IGF-I) were found to be significantly higher(P<0.05) in PCO women compared with control women, which clearly is not related to obesity. Serum glucose, insulin, and C-peptide levels were measured during a 2-hour oral glucose tolerance test(OGTT). Non-obese and obese women with PCO both(P<0.05) compared with control women demonstrated significant hyperinsulinemia after OGTT. The degree of hyperinsulinemia was found to be significantly higher in the obese women with PCO compared with the non-obese women with PCO. We concluded that obesity may contribute to hyperinsulinemia, however may not playa central role in the pathogenesis of PCO.

Objectives: To characterize autonomic dysfunction in patients with Cold hypersensitivity, their heart rate variability(HRV) were measured and analyzed with cold hypersensitivity patients, compared with those of normal population. Methods: We studied 56 patients visiting Gangnam Kyung-hee korean hospital from 1st January 2010 to 31th December 2010. Heart rate variability were obtained from 28 female patients who suffer from cold hypersensitivity and 28 healthy female controls in resting state. We studied the difference of Heart rate variability between two groups by Independent T-test using SPSS for windows(version 17.0). Results: Standard deviation of NN interval(SDNN), total power(TP), Very low frequency(VLF) in patients with cold hypersensitivity were significantly different with those of controls. While no significant differences were observed in square root of mean squared differences of successive NN intervals (RMSSD), low frequency (LF) and high frequency(HF). Conclusions: The decreased values of heart rate variability(HRV) study means that they may have some kinds of imbalance in autonomic nervous system in cold hypersensitivity patients. heart rate variabiliry(HRV) study might be a tool of diagnosis and predictors in cold hypersensitivity patients.

Background: Atypical squamous cells of undetermined significance (ASCUS) feature a wide variety of cervical cells, including benign and malignant examples. The management of ASCUS is complicated. Guidelines for office gynecology in Japan recommend performing a high-risk human papillomavirus (HPV) test as a rule. The guidelines also recommend repeat cervical cytology after 6 and 12 months, or immediate colposcopy. The purpose of this study was to determine the clinical significance of ASCUS. Materials and Methods: Between January 2012 and December 2014, a total of 162 patients underwent cervical conization for cervical intraepithelial neoplasia grade 3 (CIN3), carcinoma in situ, squamous cell carcinoma, microinvasive squamous cell carcinoma, and adenocarcinoma in situ at our hospital. The results of cervical cytology prior to conization, the pathology after conization, and high-risk HPV testing were obtained from clinical records and analyzed retrospectively. Results: Based on cervical cytology, 31 (19.1%) of 162 patients were primarily diagnosed with ASCUS. Among these, 25 (80.6%) were positive for high-risk HPV, and the test results of the remaining 6 patients (19.4%) were uncertain. In the final pathological diagnosis after conization, 27 (87.1%) and 4 patients (12.9%) were diagnosed with CIN3 and carcinoma in situ, respectively. Conclusions: Although ASCUS is known as a low-risk abnormal cervical cytology, approximately 20% of patients who underwent cervical conization had ASCUS. The relationship between the cervical cytology of ASCUS and the final pathological results for CIN3 or invasive carcinoma should be investigated statistically. In cases of ASCUS, we recommend HPV tests or colposcopic examination rather than cytological follow-up, because of the risk of missing CIN3 or more advanced disease.

Background: Our aim was to investigate the efficacy of the Pap test in combination with the ThinPrep cytological test (TCT) in screening for cervical cancer in China. Design: From March 2006 to October 2008, 988 women with the mean age $46.4{\pm}10.5$ years (range, 23-80 years) were recruited to receive cervical cancer screening. Pap test results ${\geq}$ grade III and TCT findings ${\geq}$ ASCUS/AGUS were considered abnormal. Subjects with a Pap test result ${\geq}$ grade IIb received TCT. Colposcopy and biopsies were performed in all participants, and final diagnosis was based on pathological findings. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden index for predicting CIN I or above were determined. Results: The sensitivity, specificity, PPV, NPV and Youden index of the Pap test were 43.1%, 97.2%, 70.0%, 91.9%, and 40.3%, respectively. The same values for TCT in predicting CIN were 80.0%, 63.2%, 16.0%, 97.3%, and 43.2%, respectively. The two tests in combination gave values for predicting CIN of 64.8%, 87.6%, 43.6%, 94.4%, and 53.5%, respectively. Combined testing exhibited the highest Youden index (53.4%). Conclusion: The Pap test with a reduced threshold in combination with the TCT has high sensitivity and high specificity in screening for cervical cancer.

Objectives : In the theory of Korean medicine, Citri Reticulatae Viride Pericarpium (CRVP) can soothe the liver to break qi stagnation, eliminate mass and relieve dyspepsia. This study was carried out to investigate the effects of CRVP on the apoptotic cell death in breast cancer cells. Methods : In the present experiment, the effects of CRVP on proliferation rates, type of cell death, cell cycle distribution, and intracellular oxidative stress were investigated using MDA-MB-231 cells in vitro. In addition, the effects on expression levels of caspase 3, caspase 9, Bax and Bcl-2 were also investigated. Results : Treatment with CRVP decreased proliferation rates in a dose dependent manner. ID50 (50% inhibitory dosage) was 175.4 μg/ml. In the CRVP treated group, cell volumes showed smaller than non-treated normal. In addition, CRVP increased percentage of apoptotic and sub G1 arrested cells respectively. 200 μg/ml of CRVP treatment increased intracellular ROS level significantly. Finaly the expression level of caspase 3 and Bax/Bcl-2 ratio were elevated by treatment with CRVP respectively. Conclusions : These results suggest that CRVP can trigger intrinsic apoptotic pathway in MDA-MB-231 cells.

Purpose: This study was performed to observe the correlation between Hot flush and pulse wave velocity(PWV), ankle brachial index(ABI) in the Climacteric women. Methods: We studied 63 climacteric women visiting OO hospital from 8th January 2007 to 22nd April 2009. The subjects were categorized in two groups, the hot flush group(37) and normal group(26). For the study, the subjects were selected by excluding the patients who receive treatment affect hot flush or have disease affect arterial states. We assessed PWV and ABI of two groups by Oscillometric method using VS-1000(Form PWV/ABI; Fukuda Denshi, Co., Ltd., Japan). From these results, we studied the correlation between hot flush and PWV/ABI by Wilcoxon Mann Whitney Test. Results: 1. It is shown that hot flush group was no significant correlation with normal group. There is no significant factor among R-PWV, L-PWV, R-ABI, L-ABI. However, L-ABI have shown relatively higher correlation with comparison to the other factors.(p-value<0.05) 2. R-PWV, L-PWV significantly increased in menopause group than in premenopause group though there is no relation to the hot flush. (p-value<0.01) Conclusion: Though the results showed no correlations between Hot flush and PWV/ABI in the Climacteric women, L-ABI showed relatively higher correlation with hot flush than others. R-PWV, L-PWV showed significant correlation between premenopause and menopause.

Objective: To study the mechanism of effects of AZD1480 on the SKOV3 ovarian cancer cell line. Methods: The MTT method was used to assess cellular proliferation, flow cytometry for cellular apoptosis, the scratch test to determine migration, transwell chamber assays to detect cellular invasion, plate clone experiments to detect the clone forming ability and Western blotting to determine p-STAT3 protein levels. Results: The proliferation rate, migration ability, invasiveness and the clone forming ability of SKOV3 cells were reduced after treatment with AZD1480, while apoptosis rate and chemotherapeutic susceptibility were increased. After treatment with AZD1480 plus cisplatin, the apoptosis rate increased significantly while the expression level of p-STAT3 protein was decreased. Conclusion: AZD1480 can inhibit the proliferation, invasion, metastasis and clone formation of SKOV3 cells, induce cellulsar apoptosis, increase the chemotherapeutic sensitivity and reduce the expression level of p-STAT3 protein.
