Objective: This study was designed to estimate the frequency and risk factor for edenomyosis Methods: The clinical records of 623 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital, during 5 years, from Jan. 1995 to Dec. 1999. Results: The following result were obtained. 1. Adenomyosis was found in 247 of 623 patients(39.6%) 2. The highest incidence was 40-49 years of age group, an incidence of 46.6% and mean age was 44.7 years. 3. Adenomyosis was more frequently observed in parous women than non-parous women, such as 93.1% and 6.9%, respectively. 4. Dysmenorrhea, metrorrhagia, pelvic pain and vaginal bleeding were common symptom of adenomyosis, an incidence of 28.7%, 19.0%, 18.2% and 16.2%, respectively. 5. Myoma was the most combined disease in adenomyosis, showing the incidence of 54.7%. 6. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 61.9%. 7. Preoperative diagnostic accuracy of adenomyosis was 6.9%. Conclusion: The results show that deeply understanding of the common symptoms and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

Objective: The purpose of this study was to evaluate clinical efficacy of fetal fibronectin as a marker to predictor of preterm labor. Materials & Methods: The study group consisted of sixty-eight healthy pregnant women, at gestational age between 24 and 36 weeks, who visited our department with vaginal discharge from April, 1995 to December, 1997. For comparison, we divided all of the pregnant women into two groups by the result of ROM-Check^®, positive groups(N=21) and negative groups(N=47). When preterm labor appeared, 50mg of ritodrine hydrochloride(Yutopar^®) mixed I liter of 5% dextrose solution was administered slowly intravenously. Results: 1) The gestational age at delivery and the interval time from admission to delivery in the positive groups were significantly shorter than those of the negative groups(p<0.05). 2) The positive groups had significantly lower birth weight and Apgar scores than the negative groups(p<0.05). 3) Among the negative groups, in case of tocolytics administration, the interval time from admission to delivery significantly delayed more than that time in case of no tocolytics administration(p<0.05). Conclusions: The detection of the fetal fibronectin in vaginal discharge had a useful method as a predictor of preterm labor. Tocolytics was more effective in the negative groups than in the positive groups.

본 연구에서는 풍동의 활용성과 경제성, 장비설치 및 취급의 용이성등을 고려하여 요구풍속을 결정한 후 확산부, 정체실, 수축부, 시험부등을 설계하고, 제작된 풍동에 대한 성능검사를 실시하였다. 정체부와 시험부 수축비는 9이고 시험부의 단면은 406mm×406mm 이며 길이는 1,200mm 이다. 시험부에서 얻을 수 있는 최대속도는 송풍기 회전수 1,500rpm 일때 36m/sec이다. 송풍기 동력은 19kW 이며 송풍기 형태는 원심형 임펠러를 선택하였다. 시험부의 성능을 검사하기 위해 열선유속계를 사용하여 시험부 출구 단면에서의 속도분포와 난류강도를 조사하였다. 시험부의 속도는 5m/sec 에서 30m/sec 까지의 범위에서 난류강도는 0.5%이고 벽면경계층 두께를 고려하면 유효 단면적은 약 85%이다. 제작된 풍동에 에머리 페이퍼(emery paper) 또는 트리핑 와이어(tripping wire)를 부착한 매끈한 평판과 축대칭 3차원 물체를 장치하여 경계층 속의 흐름이 난류가 되도록 하였고 발생된 난류 경계층의 특성을 분석 하였다. In the present experimental study, the range of wind speed at the test section was determined by considering the availability, economy, installation and handling of the wind tunnel, and diffuser section, settling chamber, contraction section and test section of the wind tunnel were designed and manufactured to satisfy the prescribed wind speed range. Performance of the manufactured wind tunnel was tested according to the normal testing procedure. Contraction ratio of the test section to the settling chamber is 9 and the cross section of the test section is 406mm×406mm and the test section is 1200mm long. The maximum air speed at the test section is 36m/sec for the motor speed of 1500 rpm. A centrifugal type fan is used and the maximum power required is 19kw. The hot-wire anemometer system was employed to test the performance of the wind tunnel by measuring the velocity distribution and turbulent intensity at the exit of the test section. Measured values of turbulent intensity were less than 0.5% for the range of wind speed from 5m/sec to 30m/sec. The available cross sectional area of the test section was about 85%. Flat plate and axisymmetric three dimensional body were used as models to identify the boundary layer characteristics. The boundary layers were triggered by emery paper and/or tripping wire. The characteristics of the generated turbulent boundary layers were analyzed.

Two cases of primary small cell carcinoma of the ovary occurred. One was a case of 43-year-old woman associated with hypercalcemia and the other was a case of 40-year-old woman with pulmonary type. Ovarian small cell carcinoma of the hypercalcemic type have clinicopathological, immunohistochemical, ultrastructural, and flow cytometric features that from differ from those of small cell carcinomas of the pulmonary type. It is important for therapeutic reasons to distinguish these two types of ovarian tumors from each other and from a variety of malignant small cell tumors that ovary primarily or secondarily. So, we reported these cases with a brief review of the concerned literatures.

The leiomyomas of the vulva are rare benign tumors the incidence is 0.024%~0.55% in women. There are no relationship between leiomyomas of the vulva and uterus. But there are some reports that leiomyomas of the vulva and uterus simultaneously. The leiomyomas of the vulva present without symptoms and excision with biopsy is treatment of choice. Tumors of the gynecological apparatus may present without symptoms, or they may mimic other common gynecological conditions. Because of this, any vulva mass must be considered cautiously. We reported this case with a brief review of the concerned literatures.

Prolapse of the fallopian tube into the vaginal vault after hysterectomy is a rare complication. Since most of cases may resolve before detection or remain undiagnosed, the exact incidence is still unknown. Though most common sign of tubal prolapse is tender friable tissue in vaginal cuff, with the simptoms of lower abdominal pain, dysparenunia, vaginal discharge, or postcoital spotting. The definitive diagnosis should be confirmed histologically Recently, we experienced a case of fallopian tube prolapse after abdominal hysterectomy in a 41-year-old woman and report with a brief review of the literature.
