Previously, Euptelea pleiosperma was identified as one of the useful sources containing anti-oxidative and anti-inflammatory activities for the first time in our research group. In this study, anti-obesity effect of E. pleiosperma ethanol extract (EPEE) was evaluated by using a pancreatic lipase enzyme inhibition assay and a cell culture model system. EPEE suppressed effectively pancreatic lipase enzyme activity dose dependently. Furthermore, EPEE significantly suppressed adipocyte differentiation, lipid accumulation, triglyceride contents, and triggered lipolysis activity on 3T3-L1 preadipocytes in a dose-dependent manner without cytotoxicity. Anti-adipogenic effect of EPEE was modulated by cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins ${\alpha}(C/EBP{\alpha})$, $C/EBP{\beta}$ and peroxisome proliferator-activated receptor ${\gamma}(PPAR{\gamma})$ gene and protein expressions. Taken together, these results provide the important new insight that E. pleiosperma possesses anti-obesity activities such as pancreatic lipase inhibition, anti-adipogenic, and lipolysis effects. It might be utilized as promising sources in the fields of nutraceuticals. The identification of active compounds that confer anti-obesity activity of EPEE might be needed.

Pancreatic lipase and ${\alpha}$-amylase inhibitory activities in purified extracts of pumpkin and job's tear were studied. Pancreatic lipase inhibitory activity was determined by measuring the rate of releasing oleic acid from triolein, and ${\alpha}$-amylase inhibitory activity was determined by iodometric method. The extracts of pumpkin and job's tear were purified using silica gel and C-18 gel column chromatographies. Treatment of pumpkin extract $(120\;{\mu}g/mL)$ in 3T3-L1 preadipocyte decreased differentiation about 95% and blocked accumulation of lipid. Body weights of rats fed high-fat diet containing dietary supplement decreased about 13% as compared with those fed only highfat diet. These results revealed dietary supplement is a good obesity-reducing material for decreasing lipid and carbohydrate absorptions.

과식과 폭식은 건강의 적이다. 소화불량, 역류성 식도염, 복통, 복부팽만감, 설사 등 위장 장애를 일으킬 뿐만 아니라 급성장염이나 드물지만 급성췌장염 등의 심각한 병으로까지 발전할 수 있기 때문이다. 현대인들의 만병의 근원인 비만의 원인이 되기도 한다. 특히 설과 같은 명절기간엔 평소보다 튀김이나 전, 잡채 등과 같은 기름기와 지방이 많은 음식을 더 많이 섭취하기 때문에 각별한 주의가 필요하다. 건강한 설을 보낼 수 있는 식습관에 대해 알아보자.

당뇨병을 앓고 있는 환자들 중 비만 때문에 고생하는 환자들이 매우 많다. 당뇨병의 발병 원인이 아직 완전히 다 밝혀진 것은 아니지만 유전적인 원인과 근육이나 지방조직 등 말초조직에서의 인슐린저항성, 췌장에서의 인슐린분비기능의 감소 등이 가장 큰 원인인 것으로 알려져 있다. 특히 비만이 관계하는 말초조직의 인슐린 저항성이 당뇨 발병 원인의 주요 요인으로 꼽히고 있다는 것은 주목해야 할 사항이다. 또한 비만한 당뇨인들은 체중조절이 되지 않는 만큼 혈당조절에도 실패할 수밖에 없다. 비만한 당뇨병환자분들, 올해는 체중감량으로 건강한 한해를 보냅시다.

수년간 감보로병은 감보로지방에서 처음 발견된 이래로 여러가지 이름으로 불리어졌다. 이 전염병은 양계산업을 주로 위협하며 특히, 악성 바이러스에 걸렸을 때는 더욱 피해가 심하여 양축가에게 경졔적 손실을 가져다 준다. 다행이도 백신의 사용이 가능하여 이 무서운 전염병으로 부터 피해를 예방할 수 있게 되었다. 감보로병은 1962년 미국 델라웨어주의 작은 도시 감보로에서 처음으로 알려졌으며 전염성F낭병 또는 감보로병으로 불리어진다. 원인이 되는 바이러스는 생선(전염성췌장 궤사바이러스)연체동물 및 과일 파리로부터 분리된 것으로 최근에 알려진 비르나버리데군에 속한다.

The aims of this study were to evaluate the anti-obese effects of pine needle, black tea and green tea in rats and overweight people. Supplementation of 1, 2, 4 and 8% amount to the control diet of pine needle extract and mixture groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Supplementation of 1, 2 and 4% amount to the control diet of black and green tea extracts groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Anti-obese effect in body weight gain and visceral fat mass of mixture group was higher than in other groups. In human study, extracts mixture supplementation to overweight subjects significantly decreased both body weight and body fat compared with placebo control group. In vitro study, black and green tea extracts significantly inhibited both the pancreatic lipase and ${\alpha}-amylase$ activities dose dependently. In conclusion, the anti-obese effects of pine needle, black, and green teas in rats were found. In overweight human subjects, extracts mixture decreased body weight and body fat compared with placebo control group. Anti-obese effect in black and green tea groups might be from an decrease in carbohydrate and fat digestions via inhibition of pancreatic ${\alpha}-amylase$ and lipase activities in part.

This study aimed to verify the antidiabetic effects of the unripe black raspberry extract (UBRE) in obese diabetic mice. For the experiment, animal model mice were divided into six groups: normal control, diabetic control, three experimental groups (treated with 75, 150, and 300 mg/kg single dose of UBRE), and a positive control (200 mg/kg metformin). The groups treated with 300 mg/kg UBRE and metformin had significantly reduced blood glucose and triglyceride levels in the diabetic mice compared to those in the vehicle control group. In addition, histopathological evaluation showed that UBRE increased the Langerhans area, cell number, and insulin concentration in the pancreatic islets of db/db mice. Therefore, UBRE exerts significant antidiabetic effects by decreasing the blood glucose and lipid levels, suggesting that it can be consumed as a functional diet for diabetic patients.

Purpose : To evaluate value of superparamagnetic iron oxide (SPIO) as a negative oral contrast agent in MR cholangiopancreatography (MRCP). Materials and methods : Forty-eight patients with suspected biliary tract or pancreatic diseases and six healthy volunteers were enrolled in this study. All MR images were obtained using a 1.5 T MR unit. MR-CP using fat-suppressed half-Fourier acquisition single-shot turbo spin echo (HASTE) and turbo spin echo (TSE) techniques were performed and reconstructed with maximal intensity projection (MIP). To determine the most optimal concentration of SPIO to obliterate the high signal intensity of water, a phantom experiment was conducted with various concentrations of SPIO-water mixture. Two radiologists evaluated pre- and postcontrast MRCPS. The contrast enhancement was assessed on the basis of loss of signal intensity in the stomach and duodenum. Results : In the phantom experiment, a significant increase of percentage of signal intensity loss (PSIL) occurred in concentration of 22.4 ugFe/ml (Feridex1 ml diluted with water 500 ml). Postcontrast MRCP showed an improved image quality compared with precontrast images. The rate of improvement in the diagnosis of diseases of the common bile duct and pancreatic duct was 25% (12/48). Conclusion : In patients with suspected biliary tract and pancreatic diseases, the SPIO is useful as a negative oral contrast agent for MRCP and provides an improvement of image quality.

To examine the effects of dietary fibers on gastrointestinal physiology, rats were fed with diets containing 10% sodium alginate,10% cellulose, or fiber-free diets for 5 weeks. The results obtained were as follows: The chronic consumption of sodium alginate induced a significant decrease in body weight gain and feeding efficiency, but a significant increase in length and weight of small intestine. Fecal bulk and weight were higher in fiber-fed group than fiber-free group. The chronic consumption of dietary fiber induced a significant increase in fecal output, resulting in tile decrease of apparent digestibility of protein and lipid. Pancreatic protease activity was lower in fiber-fed group than fiber-free group, whereas pancreatic amylase and lipase activities were not affected. Scanning electron microscopy(SEM) and light microscopy(LM) studies showed small intestine microvilli with numerous ridges and convolutions and goblet cells in fiber-fed groups. As a result of this study, it is concluded that the chronic consumption of dietary fiber decreases apparent digestibility of nutrients and induces morphological and biochemical adaptation of digestive organs.

The purpose of this experiment is to evaluate of optimized FS techniques for T2 weighted abdominal MRI compared of TSE-SPIR fat suppression and GE-PROSET fat suppression. All MR examinations were performed on a 1.5 T(Philips, Medical System, Achieva) scanner using 16 channel mult-coils. All images were performed in the axial plane using TSE-SPIR and GE-PROSET. The mean SNRs of the retroperitoneal and mesenteric fat for TSE-SPIR and GE-PROSET were 31.50, 4.15 and 32.39, 7.03. The mean CNRs of the bowel and retroperitoneal, mesenteric fat for TSE-SPIR and GE-PROSET were 52.69, 74.54 and 26.12, 68.78). The delineation of bowel wall margins with TSE-SPIR(2.4) and GE-PROSET(1.8) were significantly improved using TSE-SPIR. The delineation of pancreas wall with TSE-SPIR(1.90), GE-PROSET(2.80) were significantly improved using GE-PROSET. In conclusion, TSE-SPIR fat suppression was superior to GE-PROSET fat suppression in T2 WI FS abdominal MRI.
