최종열 ( Jong Yeol Choi ),김형중 ( Hyoung Jung Kim ),어완규 ( Wan Kyu Eo ),김흥열 ( Heung Yeol Kim ) 대한산부인과학회 2006 Obstetrics & Gynecology Science Vol.49 No.6

목적: 자궁육종은 중배엽기원의 비교적 드문 악성종양으로서 자궁에서 발생하는 악성종양들 중에 약 2-6%를 차지하는 가장 악성도가 높은 종양이며 그 진단과 치료에 있어 어려움이 따른다. 이 논문의 목적은 자궁육종의 임상병리학적 소견 및 환자의 예후를 알아보고자 하였다. 연구 방법: 1996년 1월부터 2004년 12월까지 본원 산부인과에서 조직학적으로 자궁육종으로 진단된 환자를 대상으로 후향적 분석을 통해 임상적 결과 및 생존율을 평가하였다. 결과: 자궁육종 환자의 연령분포는 28세에서 71세 사이였고 평균연령은 48세이었다. 흔한 임상증상으로는 비정상적 자궁출혈, 복부 동통 및 하복부 종괴 등이었다. 자궁육종 환자의 전체 5년 생존율은 48.9% 이었고 평균 생존기간은 73.6개월이었다. 연령에 따른 전체 5년 생존율을 비교할 때, 50세 미만 24명의 생존율(69.1%)은 50세 이상 16명의 생존율 (24.6%)보다 통계학적으로 유의하게 좋은 예후를 나타내었다. (p=0.0139). 조직학적 유형에 따른 분류에서 각각의 환자 분포는 자궁근육종 21명 (52.5%), 자궁내막기질육종 8명 (20.0%), 악성혼합뮬러씨종양 10명 (25.0%) 그리고 지방육종1명 (2.5%)이었으며, 악성혼합뮬러씨종양의 전체 5년 생존율이 자궁근육종과 자궁내막기질육종의 전체 5년 생존율보다 통계학적으로 유의하게 더 나쁜 예후를 나타내었다. (p=0.0423). FIGO의 수술적 병기에 따른 분류에서 각각의 환자 분포는 1기 26명 (66.7%), 2기 4명 (10.3%), 3기 5명 (12.8%) 그리고 4기 4명 (10.3%) 이었으며, 병기 1기와 2기의 전체 5년 생존율 (61.8%)이 병기 3기와 4기의 전체 5년 생존율 (11.1%)보다 통계학적으로 유의하게 더 좋은 예후를 나타내었다. (p=0.0011). 통계학적으로 유의하지는 않았지만, 세포유사분열수 10개/10 HPF 미만의 환자 14명의 전체 5년 생존율 (83.9%) 10개/10 HPF 이상의 환자 13명의 전체 5년 생존율 (38.5%)보다 좋은 예후를 보이는 경향 있었으며 (p=0.0568), CA-125 35 U/mL 미만의 환자 6명의 전체 5년 생존율 (83.3%)은 35U/ml 이상의 환자 12명의 전체 5년 생존율 (20.8%)보다 좋은 예후를 보이는 경향이 있었다. (p=0.0580). 그러나 폐경 여부와 치료 방식에 따른 전체 5년 생존율 비교에서는 통계학적으로 유의한 예후인자가 아닌 것으로 나타났다. 결론: 자궁육종은 안 좋은 예후를 나타내는 악성종양으로서, 우리의 연구에 의하면 나이, 조직학적 유형, 병기가 통계학적으로 유의한 예후인자로 나타났다. Objective: Uterine sarcomas are rare tumors of mesodermal origin and constitute 2-6% of uterine malignancies. They are the most malignant group of uterine tumors and present difficult problems with regard to diagnosis and treatment. The aim of this study is to investigate the clinicopathologic finding and outcome of patients with uterine sarcoma. Methods: From Jan. 1996 to Dec. 2004, 40 patients with histologically proven uterine sarcomas at Gospel Hospital were evaluated for their clinical profile and survival retrospectively. Results: The age of patients with uterine sarcoma ranged 28 to 71 years, and the mean age was 48.0 years. The common presenting symptoms were abnormal uterine bleeding, abdominal pain and lower abdominal palpable mass. The overall 5-year survival rate of uterine sarcoma was 48.9% and the mean survival time was 73.6 months. The overall 5-year survival rate of 24 patients less than 50 years was significantly better than that of 16 patients more than 50 years, 69.1% vs 24.6% (P=0.0139). When classified according to histologic type, there were 21 cases (52.5%) of leiomyosarcoma (LMS), 8 cases (20.0%) of endometrial stromal sarcoma (ESS), 10 cases (25.0%) of malignant mixed mullerian tumors (MMMT) and 1 case (2.5%) of liposarcoma. The overall 5-year survival rate of MMMT was significantly worse than that of LMS and ESS, 26.7% vs 49.0% and 100.0%, respectively (P=0.0423). Classifying according to the FIGO surgical staging criteria, we found the following distribution; stage I of 26 cases (66.7%), stage II of 4 cases (10.3%), stage III of 5 cases (12.8%) and stage IV of 4 cases (10.3%). The overall 5-year survival rate of stage I and II was significantly better than stage III and IV, 61.8% vs 11.1% (P=0.0011). The overall 5-year survival rate of 14 patients less than 10 mitotic figures per 10 high-power microscopic fields had a tendency to good prognosis than that of 13 patients more than 10 mitotic figures per 10 high-power microscopic fields, 83.9% vs 38.5% (P=0.0568). The overall 5-year survival rate of 6 patients less than 35 U/mL of CA-125 had a tendency to good prognosis than that of 12 patients more than 35 U/mL of CA-125, 83.3% vs 20.8% (P=0.0580). However, menstrual status and treatment modality were not significant prognostic factors. Conclusions: Uterine sarcoma are aggressive tumors with a poor prognosis. Age, histologic type, and stage were statistically significant prognostic factors for overall survival in uterine sarcomas.

Enhanced DC-Operated Electroluminescence of Forwardly Aligned   p/MQW/n InGaN Nanorod LEDs via DC Offset-AC Dielectrophoresis

Eo, Yun Jae,Yoo, Gang Yeol,Kang, Hyelim,Lee, Young Ki,Kim, Chan Sik,Oh, Ji Hye,Lee, Keyong Nam,Kim, Woong,Do, Young Rag American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.43

<P>We introduce an orientation-controlled alignment process of p-GaN/InGaN multiquantum-well/n-GaN (p/MQW/n InGaN) nanorod light-emitting diodes (LEDs) by applying the direct current (DC) offset-alternating current (AC) or pulsed DC electric fields across interdigitated metal electrodes. The as-forwardly aligned p/MQW/n InGaN nanorod LEDs by a pulsed DC dielectrophoresis (DEP) assembly process improve the electroluminescence (EL) intensities by 1.8 times compared to the conventional AC DEP assembly process under DC electric field operation and exhibit an enhanced applied current and EL brightness in the current-voltage and EL intensity-voltage curves, which can be directly used as the fundamental data to construct DC-operated nanorod LED devices, such as LED areal surface lightings, scalable lightings (micrometers to inches) and formable surface lightings. The enhancement in the applied current, the improved EL intensity, and the increased number of forwardly aligned p/MQW/n InGaN nanorods in panchromatic cathodoluminescence images confirm the considerable enhancement of forwardly aligned one-dimensional nanorod LEDs between two opposite electrodes using DC offset-AC or a pulsed DC electric field DEP assembly process. These DC offset-AC or pulsed DC electric field DEP assembly processes suggest that designing for these types of interactions could yield new ways to control the orientation of asymmetric p/MQW/n InGaN diode-type LED nanorods with a relatively low aspect ratio.</P>

Objectives : The aim of the study was to assess the hitologic appearance according to endometrial thickness in postmenopausa endometrial fluid accumulation women. Methods : A group of 20 postmenopausal women with an endometrial fluid accumulation confirmed by ultrasonography and underwent Dilatation & Curettage. The patients were divided into two groups according to the endometrial thickness(ET). Sixteen women had thin endometrium (<4mm) and four women had the thick endometrium (≥4mm). Results : When ET was ≥ 4mm, proliferative endometrium was found in 2 patients (50%), atrophic endometrium was in I patient (25%) and endometritis was in I patient (25%). When ET was < 4mm, atrophic endometrium was found in 14 patients (87%), A majority of patients with ET of less than 4mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as abserved by ultrasound. Conclusion : The presence of endometrial fluid accumulation in postmenopausal patients without any symptoms seems to be a benign condition. Normal endometrium of less than 4mm observed by ultrasound in postmenopausal women without vaginal bleeding dose not necessarily need further surgical investigation.
