1. Backgrounds and Aims Human being is divided into 4 constitution types(Taeyangin, Soyangin, Taeumin, and Soumin). According to Sasang Constitutional Medicine[SCM] Each constitution has its own incidence, treatment and prevention of disease. The purpose of this study is to find the relation of dietary habits, life styles and Psychosocial stress with obesity in each Sasang Constitution. 2. Methods 975 subjects who have received health examinations and diagnosis of Sasang Constitution at Kyung-hee Medical Center were divided into each constitutional group. Each constitutional group was then divided into obese group and normal group. We evaluated risk factors of obesity such as dietary habits, life styles, and Psychosocial stress. These data were statistically analysed to investigate the relations between risk factors and obesity. And then significant factors were analysed by multinomial logistic regression analysis to get each odds ratio. 3. Results In a multinomial logistic regression analysis adjusted for age and sex, promotion of appetite and overeating or excessive diet elevated risks of obesity in Taeumin, promotion of appetite and high speed of diet elevated risks of obesity in Soyangin, and Psychosocial stress elevated risks of obesity in Soeumin. 4. Conclusions The results suggest that promotion of appetite and overeating or excessive diet may be major risk factors for obesity in Taeumin, promotion of appetite and high speed of diet in Soyangin and Psychosocial stress and dyschezia in Soeumin.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

The Asynchornous transfer mode (ATM) can be efficiently used to transport apcket data services. The switching system will support voice and packet data service simultaneously from end to end applications. To guarantee the quality of service (QoS) of the offered services, a source rate to send packet data is needed to control the network overload condition. Most existing control algorithms are shown to provide the threshold-based feedback control technique. However, real-time voice calls can be dynamically connected and released during data services in the network. If the feedback control information delays, a quality of the serviced voice can be degraded due to a time delay between the source and the destination in the high speed link. An adaptive algorithm based on the optimal least mean square error technique is presented for the predictive feedback control techinique. This algorithm is used to attempt predicting a future buffer size from weight(slope) adaptation of unknown functions, which are used for feedback control. In this paper, we have presented simulation results, which are related to the effective use of the algorithm.

고삼 메탄올 추출물로부터 분리한 flavonoids를 IR, NMR등의 분광학적인 방법으로 Leachianone A(LA)과 Sophoraflavanone G(SFG)로 동정하였고, 카드뮴의 세포독성효과를 고삼 및 고삼추출물이 방어할 수 있는 지를 검색하기 위하여 NIG 3T3 세포에 고삼 및 LA와 SFG, LA+SFG를 처리하고 MTT assay 및 광학현미경으로 세포의 생존률을 검색하여 다음과 같은 결론은 얻었다. MIT의 흡광도는 카드뮴의 농도에 의존하여 감소하였으며, IC_50인 MTT50은 12.5??이었으며 카드뮴을 IC_50농도로 처리하고 고삼 및 LA, SFG, LA+SFG를 각 화합물의 자체 세포독성을 갖지 않는 농도로 처리한 후 MTT assay로 세포 생존율을 측정한 결과 LA, SFG, LA+SFG 처리군들은 카드뮴 처리군(MTT_50)에 비해 세포생존률이 증가되었으며 이들은 고삼 및 고삼추출물의 농도에 의존적으로 증가되었고 각각의 단일 화합물보다 두 화합물 LA+SFG 병용처리군에서 수복 효과가 더 좋은 것으로 나타났으며 광학현미경적 소견에서도 세포재생이 뚜렷하게 보였다. 이상과 같이 고삼에서 분리한 flavonoids가 카드뮴 독성에 의하여 손상된 NIH 3T3 섬유아세포의 재생효과에 영향이 있는 것으로 판단된다. The aim of this study was to assess the antitoxic compounds, flavanones (Leachinanone A=LA and Sophora flavanone G=SFG), from Sophora flavescents (S. Flavescens). We investigated the possibility of antitoxicity of LA and SFG against NIH 3T3 fibroblasts cell lines using colorimetric MTT[3-(4-5-dimethylthiazol-2-yl)-2-5diphenyl-2H-tetra-azolium bromide] assay. The results were as follows : After cadmium was treated against NIH 3T3 cell lines, we determined IC_50. Accordingly we have examined the detoxification effects of S. flavescens, LA and SFG under cadmium IC_50=12.5?? and was carried out to observe morphological changes by the light microscopic study. In NIH 3T3 cells, Sophora flavescens, LA, SFG and LA+ SFG showed inhibitory effects on the cytotoxicity of cadmium and these detoxication effects increased in proportion to the concentration of these drugs. These results suggest that LA and SFG from S. flavescens retain a potential antitoxic activity.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.
