N/A Objective : The aim of this study was to evaluate the clinical experiences of patients with the primary tubal cancer diagnosed and treated in the Department of Obstetrics and Gynecology, Gacheon Medical School from January 1996 to December 2000. Methods : Age, symptoms, Pap smear, CA-125, preoperative diagnosis, mode of surgery, stage, additional pathologic finding, mode of adjuvant therapy and survival periods of patients were reviewed retrospectively. Results : The mean age of patients was 57.4 years. The symptoms were vaginal spotting, leukorrhea and pelvic mass. Three patients were treated by simple hysterectomy and both salpingoophorectomy. Staging laparotomy was done in 4 patients. Three patients were in stage I, 2 patients were in stage II and 2 patients were in stage III. Endometrial adenocarcinoma was present in 1 patient and endometrial hyperplasia was present in 1 patient. The mean follow-up period of five patients were 25.4 months and 2 patients were lost for follow-up. Conclusions : The primary tubal cancer was rare gynecologic malignancy and the preoperative diagnosis was difficult due to non-specific symptoms and signs. Staging laparotomy and adjuvant chemotherapy should be done like in ovarian cancer. More studies may be needed for the associated endometiral diseases.

By using the ${\beta}$-tyrosinase of Citrobacter freundii KCT2006, which was cloned and overexpressed in Escherichia coli, 3,4-dihydroxy phenyl-L-alanine (L-DOPA) was synthesized efficiently from pyrocatechol, sodium pyruvate, and ammonium acetate. Optimal temperature and pH for the reaction were determined to be about 18$^{\circ}C$ and 8.5, respectively. The effects of substrate concentrations were also examined at different concentrations of ammonium acetate, sodium pyruvate, and pyrocatechol. Ammoniumacetate and sodium pyruvate increased the reaction rate until the concentrations reached to 300mM and 50mM, respectively. Although pyrocatechol showed the optimal concentration at 20mM, it was controlled between 20mM and 50mM to avoid the depletion of substrate during the enzymatic synthesis. Meanwhile the synthetic rate was improved about 20% when ethanol was included in the reaction solution. Based on above results, a reaction medium for the productin of L-DOPA was prepared and incubated with 1 unit/ml of ${\beta}$-tyrosinase. Pyrocatechol and sodium pyruvate was added to the reaction solutin intermittently to avoid the substrate depletion during the enzymatic reaction. After 24 hour of reaction, 31.6g/l of L-DOPA was accumulated in the reaction solution as soluble and precipitated ones and the conversion yield was about 85.2%.

목적 : 미세침윤성 자궁경부암에서 침윤 정도에 따른 조직학적 특징, 치료 방법 및 합병증과 임상적 특징의 상관 관계를 평가하여 적절한 치료 방향을 설정하고자 하였다. 연구 방법 : 1997년 1월 1일부터 2001년 12월 31일까지 가천의대 길병원 산부인과에서 1994년 FIGO 병기에 따라 미세침윤성 자궁경부암으로 진단 받은 137명의 환자를 대상으로 원추생검술, 제1형, 제2형 및 제3형 자궁절제술을 시행하여 침윤 깊이를 1 mm 미만, 1-3 m Objective : To evaluate correlation the of histological variables and the clinical features of microinvasive cervical cancer with the depth of invasion and to establish the adequate therapeutic modality. Methods : One hundred and thirty-seven patients wit

Prenatal Ultrasonographic findings of meconium peritonitis show calcificalion, and abdominal echogenic masses such as pseudocyst. Also, we can find availability of 3 dimensional ultrasonography above these descriptions. We present a case of meconium peritonitis in uterus which was diagnosed by means of prenatal 2D & 3D ultrasonography with brief review of literatures.

재조합 대장균에서 대량발현 시킨 Citrobacter freundii KCTC 2006 유래이 효소 β-tyrosinase를 이용하여 pyrocatechol, sodium pyruvate, ammonium acetate로부터 3,4-dihydroxy phenyl-L-alanine을 생산하기 위한 연구를 수행하였다. 이 효소반응에 적합한 온도 및 pH 조건은 각각 18℃와 8.5로 결정되었고, 반응액 중의 ammonium acetate와 sodium pyruvate의 농도는 각각 300 mM, 50 mM 이상으로 조절하는 것이 적합하였다. Pyrocatechol의 경우는 20 mM에서 가장 높은 반응성을 나타냈으나, 기질을 반복적으로 첨가하며 장시간 동안 효소반응을 수행하는 경우에는 pyrocatechol의 고갈을 피하기 위하여, 20 mM에서 50 mM 사이로 조절하였다. 한편, 반응액 중에 ethanol을 10% 첨가한 경우에는 반응속도가약 20% 증가하였다. 이상과 같은 효소반응특성에 기초하여 조제한 기질용액에 β-tyrosinase를 1 unit/㎖ 농도로 가하고, pyrocatechol과 pyruvate가 고갈되지 않도록 간헐적으로 첨가하면서 효소반응을 수행한 결과, 24시간 만에 85.2%의 수율로 31.6g/ℓ의 3,4-dihydroxyphenyl-L-alanine를 생산할 수 있었다.
