OBJECTIVE: Abnormal uterine bleeding is the most common disorder of gynecologic department. Organic causes of abnormal uterine bleednig are chronic cervicitis, submucosal myoma, endometrial polyp, endometrial malignancy. To find the exact cause of uterine bleeding, hysteroscopic endometrial biopsy was used. METHODS: 214 patients were included in the study, who received hysteroscopic endometrial biopsy from Feb. 2000 to Dec. 2002 with abnormal uterine bleeding, negative in urine pregnancy test, normal in cervix cytology, and without organic lesion causing uterine bleeding in pelvic examination and ultrasonography. Age, parity, hysteroscopic biopsy result were analyzed retrospectively. RESULTS: Mean age of study group was 42 and mean parity was 2.75. When final hysteroscopic biopsy histology were analysed, proliferative phase was most common (28.9%). Next followed secretory phase (18.2%), simple hyperplasia (13.5%), endometrial polyp (9.8%), chronic endocervicitis (5.1%). Submucosal myoma (4.2%), endometrial cancer (4.2%). Complex hyperplasia were detected in 3.2%. Of 214 patients, who complained uterine bleeding, only 99 (47.1%) patients were proved true non- organic uterine bleeding on hysteroscopic biopsy. Remainder had organic disorder (39.8%). CONCLUSION: When a patient visits the hospital with abnormal uterine bleeding, doctor should be suspicious of endometrial organic disease and treat the patient under exact diagnosis. In these patients, hysteroscopic examination and biopsy were very useful and safe method to determine exact diagnosis and treatment plan.

Microinvasive carcinoma of the uterine cervix(FIGO stage IA) has been reported as highly curable disease even with conservative surgery such as conization and simple hysterectomy. Nevertheless, the surgical management for microinvasive carcinomas has been proposed varying from conservative surgery to radical hysterectomy with pelvic nodes dissection according to different diagnostic criterias for microinvasive carcinoma. We reviewed 512 patients who had been diagnosed as microinvasive carcinoma of the uterine cervix at the Department of Obstetrics and Gynecology, Samsung Cheil Hospital and Women's Healthcare Center from Jan. 1988 to Dec. 1995. Among them, 376 patients were included in this study satisfying guided criterias such as proper management and follow up more than at least one year, and they were analyzed retrospectively based on the clinicopathologic characteristics, pattern of surgical management and postoperative status.

BACKGROUND: The aim of this study is to evaluate our clinical experience with the Carbomedics heart valve prosthesis. MATERIAL AND METHOD: Between Aug. 1988 and Dec. 1998, 294 Carbomidics valves were implanted in 235 patients(mitral; 143, mitral and aortic; 59, aortic; 33) The mean age at operation is 40.0+/-12.3 years(range 7 to 68 years); 63.8% (150patients) were woman. Follow up was 97.4% complete and mean follow up time was 5.7years with a total of 1209.2 patient-years. RESULT: The hospital mortality was 8.9%(mitral; was 95.2+/-1.6%(mitral ; 94.9+/-2.1%, mitral and aortic 95.0+/-3.7%, aortic 96.2+/-3.8%). Actual freedom rates from complications(linearized rates in parentheses) were fllowings; thromboembolism 96.2+/-1.5%(0.59%pt-yr), valve thrombosis 96.7+/-1.4%(0.5%/pt/yr), anticoagulant related hemorrhage 98.3+/-1.0%(0.25%/pt-yr), perivalvular leak 99.0+/-1.4%(0.5%/pt-yr), endocarditis 98.7+/-1.0%(0.25%/pt-yr), perivalvular leak 99.0+/-0.7%(0.17%pt-yr), endocarditis 98.7+/-1.0%(0.17%+/-pt-yr) and overall valve-related complications 88.9+/-2.5%(1.68%/pt-yr). CONCLUSION: The clinical performance of the Carbomedics valve was quite satisfactory with a low incidence of valve related mortality and morbidity.

Pulmonary mucinous cystic tumor of borderline malignancy is very rare and distinguished from bronchogenic cyst or adenocarcinoma of bronchoalveolar type. We present the case of a 63-year-old woman with a right lower lobe mass, found by chest radiographs. The preoperative diagnosis was made as bronchoalveolar cancer by percutaneous needle aspiration of mass. Right lower lobectomy and lymph node dissections were performed. The lobectomy specimen contained variable sized multilocular cystic mucous masses, filled with mucus. Microscopically, the cystic masses are lined with tall columnar mucinous epithelium but some area contains focal cellular atypism and bronchoalveolar cancer like foci. This foci are lack of cellular atypism consistent with bronchoalveolar cancer cell. After lobectomy the patient has remained free from recurrence and distant metastasis for following 12 months period. Pulmonary mucinous cystic tumor of borderline malignancy appears to have a favorable prognosis and should be distinguished from other lung neoplasms.

In this study, we examined the effects of a two-step culture system, which involves the use of different culture media for early cleavage and later stage embryos, on the in vitro development of bovine embryos. We also investigated the effect of glucose, phosphate and citrate on the in vitro early developmental period of bovine embryos in a two-step culture system. Moreover, the supplementation of different protein sources (BSA-V, BSA-FAF and FBS) during IVC did not affect the frequency of blastocyst development. Using two-step culture, embryos were cultured in protein-free media for an initial 5 days. This was then followed by the same culture media or an FBS supplemented media. The developmental rates of blastocysts in the FBS containing group were significantly higher than in the replaced with no serum containing group. Embryos cultured in mSOF supplemented with 1.5 mM glucose plus 1.2 mM phosphate were significantly inhibited. The inhibition of developmental competence by glucose plus phosphate was consistent with the existence of 0.5 mM sodium citrate. This study indicates that a two-step culture system, which applies different conditions for early cleavage embryos, i.e., serum-free media, vs. later stage embryos, with serum containing media, may be effective for in vitro production systems. In addition, the developmental competence of bovine embryos was depressed in the presence of glucose plus phosphate as compared to either alone or the absence of both. Therefore, the avoidance of this negative effect should allow more optimal conditions to be developed for in vitro production.

Coronary artery bypass grafting on the beating heart is no longer new to any cardiac surgeon. What matters nowadays is stablizing the heart without impairing the hemodynamics. We describe a simple and safer technique to move the anterolateral coronary to a center in the operation field. The empty blood bag connected to 50 cc syringe is put underneath the left venricle. Simply inflating the air into the blood bag gradually displaces the heart and rotate the lateral wall of the ventricle to the midline position. Therefore, we suggest "Blood Bag" method as a different way of exposing heart.
