Objectives : This study was performed to find out the relationships between abdominal fat and eating attitude in obese climacteric women. Methods : 42 obese climacteric women were recruited in August 2007. Anthropometry has been done and abdominal fat distribution had been assessed by CT scan at the level of L4-5 and eating attitude was measured using Korean Eating Attitude Test-26. Results : There were significant correlations between body mass index, percent of body fat and eating attitude. Total abdominal fat and visceral fat also increased with KEAT-26. Conclusions : There were relationships among eating attitude total fat, abdominal fat and visceral fat in obese climacteric women.

Malignant transformation of teratoma in the anterior mediastinum is rare; the mass usually has a long history and is seen in older patients. We report a case of teratoma with malignant transformation in the anterior mediastinum, complicated by rupture. CT revealed a lobulated, inhomogeneous cystic mass with a fat component and wall calcifications. The lateral wall was disrupted and consolidation in the adjacent left upper lobe was noted, suggesting rupture. A heterogeneously enhanced solid portion, obliterating the fat plane between the mass and the great vessels was present in the medial aspect of the mass, and pathologic examination demonstrated the presence of adenocarcinoma.

본 연구는 고지방식이로 유도된 제2형 당뇨 동물모델에서 잠상산물의 항당뇨 및 지질개선 효과를 규명하기 위하여 C57BL/6N 마우스에 14주간 잠상산물 분말(ML, SK, MF, CT)을 급여한 후 제2형 당뇨의 임상적 지표 및 인슐린 신호 전달체계에 미치는 영향을 분석하였다. HFD군보다 잠상산물을 급여한 군들의 체중증가량이 감소하는 경향이었으며, 혈장 포도당 및 인슐린 농도는 HFD군보다 ML분말을 급여한 군에서 특히 감소하였다. 혈장 T-C 농도는 HFD군에 비하여 ML과 SK 분말 급여 군에서 유의적으로 감소하였으며, 혈장 HDL-C 농도 및 HTR은 HFD군보다 ML군과 SK군에서 현저히 증가하였다. 간 조직 지질 농도는 HFD군보다 잠상산물을 급여한 네 군 모두에서 TG와 T-C 농도의 유의적인 감소가 나타났다. 이상의 결과 잠상산물 중 ML분말이 혈장 포도당, 인슐린, T-C 및 TG 농도를 가장 효과적으로 감소시켰으며, 혈장 HDL-C 농도 및 HTR은 증가시켰다. 또한, 내장지방 조직의 AKT, S6K, 그리고 AMPK의 활성도 증가시킨 것으로 보아 고지방식이에 의한 인슐린 저항성 및 지질 대사를 개선한 것으로 생각된다. 향후 ML의 인슐린 저항성 개선 효과에 대해 더 깊이 있는 기전연구가 수행된다면 제2형 당뇨환자를 위한 건강기능성 식품으로 개발될 수 있을 것으로 생각한다.

Truncal obesity associated with insulin resistance and metabolic syndrome increase the likelihood of hypertension, various cardiovascular diseases, hyperlipidemia and coronary heart diseases. International Diabetes Federation (IDF) experts recognized that it is necessary to develop the simple diagnostic tool which is applicable to diagnose truncal obesity worldwide, and proposed the method using a waist circumference but there is a limit to estimate subcutaneous fat distribution. However, waist line is also influenced by total fat capacity less than the intra abdominal fat. The more having severe obesity, the more correlation coefficient between waist line and intra abdominal fat is low. Therefore, this thesis defines a new abdominal impedance measurement position and impedance-index to analysis central obesity. This proposes the new model to estimate abdominal obesity using the abdominal impedance-index and CT images acquired fro 160 Korean subjects. The proposed model shows that the abdominal fat distribution has a higher correlation than waist line. (Adj R2=0.809, 0.667 and 0.687 with abdominal fat area, visceral fat area and subcutaneous fat area respectively).

Object The purpose of this study is to evaluate the effect of far-infrared (FIR) therapy on weight loss. Method Thirty five participants (BMI ${\geq}25kg/m^2$) were recruited. Body weight, Waist circumference (WC), Bio Impedance Analysis (BIA), abdominal fat Computer Tomography (CT) scanning were evaluated. Results of 25 women were analyzed. Result After 6 weeks of FIR therapy, there was significant efficacy on obese women in body weight, WC, Body fat mass (BFM), and Visceral fat area (VFA). But there was no efficacy in Total fat area (TFA), and Subcutaneous fat area (SFA). Conclusion This study suggests that FIR therapy might be an effective way to promote weight and abdominal visceral fat loss in Korean obese women.

Purpose: This systematic review was planned and performed in order to determine the clinical effectiveness of acupuncture for non-alcoholic fatty liver disease (NAFLD). Methods: We searched related randomized controlled trials in several medical online databases, including China National Knowledge Infrastructure (CNKI), Excerpta Medica dataBASE (EMBASE), Public/Publisher MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), National Digital Science Library (NDSL), and Research Information Sharing Service (RISS). NAFLD related outcomes were extracted from the included trials and meta-analyzed. Results: From the 8 included trials, the values of the following examinations were extracted: liver ultrasonography, liver CT, body fat CT, aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, fasting blood sugar (FBS), hosmeostatic model assessment for insulin resistance (HOMA-IR), weight, body mass index (BMI), waist hip ratio (WHR), obesity degree, body fat mass, body fat rate, leptin, malondialdehyde (MDA), and super oxide dismutase (SOD). In the 4 outcomes, cure rate in liver ultrasonography (RR=1.56; 95%CI=1.05~2.31; P=0.03), cure rate in liver CT (RR=2.23; 95%CI=1.33~3.72; P=0.002), TC (MD=-0.78; 95%CI=-1.41~-0.15; P=0.02), and TG (MD=-2.05; 95%CI=-3.88~-0.21; P=0.03), acupuncture was more effective than the control intervention. Conclusions: In this meta-analysis, acupuncture relieved hepatic steatosis, and reduced TC, and TG in NAFLD patients. more well-planned studies are still needed due to the heterogeneity and the considerable methodological flaws in the analyzed trials.

본 논문은 CT 영상을 이용하여 체지방과 근육의 체적 및 비율을 분석하는 알고리즘 개발에 대하여 기술한다. CT 영상에는 체지방, 근육, 공기, 뼈등의 구성성분들이 서로 다른 명암값을 가지고 분포한다. 이 논문에서는 히스토그램을 통하여 각 구성성분에 대한 명암값을 찾아내었다. 찾아낸 명암값에 따라 체지방과 근육 그리고 뼈, 공기에 각각 색을 입혀 시각적으로 표현하여 체지방과 근육의 분포와 비율을 볼 수 있는 환경을 만들고 수치적으로 체적 및 비율의 결과 값을 출력하는 알고리즘을 개발하였다. 또한 단계적인 체지방 측정 프로그램을 위해 DB 환경을 구축하여 모든 자료를 저장하고 불러올 수 있는 환경을 만들어 체지방 측정 알고리즘을 완성하였다. 알고리즘은 돼지 실험에서 측정된 체지방과 비교하여 정확성을 검증한 결과 약 92.86%의 정확도를 보였다.

Background: Magnetic resonance (MR) image guided radiation therapy system, enables real time MR guided radiotherapy (RT) without additional radiation exposure to patients during treatment. However, MR image lacks electron density information required for dose calculation. Image fusion algorithm with deformable registration between MR and computed tomography (CT) was developed to solve this issue. However, delivered dose may be different due to volumetric changes during image registration process. In this respect, synthetic CT generated from the MR image would provide more accurate information required for the real time RT. Materials and Methods: We analyzed 1,209 MR images from 16 patients who underwent MR guided RT. Structures were divided into five tissue types, air, lung, fat, soft tissue and bone, according to the Hounsfield unit of deformed CT. Using the deep learning model (U-NET model), synthetic CT images were generated from the MR images acquired during RT. This synthetic CT images were compared to deformed CT generated using the deformable registration. Pixel-to-pixel match was conducted to compare the synthetic and deformed CT images. Results and Discussion: In two test image sets, average pixel match rate per section was more than 70% (67.9 to 80.3% and 60.1 to 79%; synthetic CT pixel/deformed planning CT pixel) and the average pixel match rate in the entire patient image set was 69.8%. Conclusion: The synthetic CT generated from the MR images were comparable to deformed CT, suggesting possible use for real time RT. Deep learning model may further improve match rate of synthetic CT with larger MR imaging data.

본 실험은 타우린이 고지방 사료를 급여한 산란계의 생산성, 계란 품질, 혈액 성상, 간 조직의 지질 및 지질과산화물 수준에 미치는 영향을 평가하였다. 45주령 Hy-Line 갈색계 280수를 4개의 처리구로 구분하여 처리구당 7반복, 반복당 10수씩 배치하여 4주간 실시하였다. 실험 처리구는 기초 사료를 대조구로 하고, 기초 사료+0.5% 타우린(CT), 기초 사료+5% 대두유(HF) 그리고 기초 사료+5% 대두유+0.5% 타우린(HFT)로 구분하였다. 난중은 CT가 대조구보다 유의적으로 낮았으나(P<0.05), HFT는 대조구 그리고 HF와 비교하여 비슷한 수준이었다. 혈청 중 총 콜레스테롤, 중성지방 그리고 GOT 농도에서 HFT는 HF보다 유의적으로 각각 약 30%, 36% 그리고 20% 감소하였다(P<0.05). 간 조직에서 중성지방 농도는 HFT보다 HF보다 약 28% 낮은 경향이었으며, 지질과 산화물 농도는 HFT가 HF보다 유의적으로 약 25% 감소하였다(P<0.05). 따라서 본 연구 결과, 고지방 사료에 타우린의 급여는 산란계의 생산성에 영향을 미치지 않으면서 혈청 중 총 콜레스테롤과 중성지방 농도를 개선하였으며, 간 조직의 지질과산화물 농도를 감소시키는 것으로 평가되었다.
