규칙적인 운동은 혈압을 낮춰주고 체중조절과 스트레스 해소에도 도움을 주기 때문에 협심증이나 심근경색과 같은 관상동맥질환을 예방하는데 효과가 있다. 동맥경화증을 촉진시키는 위험인자로는 고혈압, 고지혈증, 당뇨병, 비만, 지나친 흡연, 운동부족 등을 들 수 있으며, 동맥경화의 진행은 어려서부터 시작되어 연령의 증가와 어불어심해진다. 특히, 여자보다 남자에게서 더 심하다. 동맥경화증 위험인자가 있는 사람의 경우 식습관과 생활양식, 그리고 운동처방으로 동맥경화성 질환을 예방하는 것이 중요하다. 식이섬유는 체내에서 소화관의 운동을 촉진하여 장관내 체류기간을 단축시키며 콜레스테롤의 흡수를 저해하여 비만, 고지혈증, 동맥경화 및 대장암 등을 예방할 수 있다. 각종 채소류와 해조류는 불포화지방산이 다량으로 함유된 식품으로서 장내에서 콜레스테롤 흡수를 방해하는 역할을 한다. 또한 식물성 기름에 함유되어 있는 필수지방산과 불포화지방은 콜레스테롤의 대사를 촉진하는 반면 흡수를 방해하며, 과일류에는 수용성 식물섬유인 팩틴이 함유되어 있어 체내의 콜레스테롤치를 떨어뜨린다. 콜레스테롤 및 포화지방산이 적고 불포화지방산이 많은 음식을 섭취하도록 하며 식이요법만으로도 콜레스테롤치를 10~15% 감소시킬 수 있다. 운동과 식이를 병행하여 운동을 지속적으로 장기간 할 때 효과가 매우 크다. 운동은 유산소성 운동으로서 운동강도는 HRmax의 60~80$\%$ $Vo_2$ max 50~70$\%$), 운동시간은 15~60분/day, 운동빈도는 3-6회/week가 바람직하다. 특히 심한 고혈압의 경우에는 환자의 상태에 따른 운동처방의 배려가 있어야 되며, 의사와 상의하여 전문적인 처방이 필요하다. 확인되었다.H, ENO1, ADH1 promoter 순으로 나타났지만, 초기 포도당 농도가 높을 때나 에탄을 생산이 심각한 유가식 배양에서는 ENO1 promoter가 inulinase의 구성적 발현ㆍ생산에 더 적합할 것으로 사료된다.라서 체중조절을 위해서는 식이제한 보다는 자유로운 식이 섭취의 방법을 통해 더 많은 운동기간을 가지고 운동을 한다면 체중조절은 물론 근육 대사를 원활히 하여 건강한 생활을 할 수 있으리라 기대한다.공정에서 매우 효과적으로 이용될 수 있을 것으로 판단된다.게 기여하리라고 전망된다.

Metabolic syndrome, defined as the clustering of several metabolic disorders including obesity (waist circumference ${\geq}90$ if male or ${\geq}80$ if female, cm), dyslipidemia ($TG{\geq}150$ or HDL-C<40 if male or <50 if female, mg/dl), hypertension ($BP{\geq}130/85mmHg$) and hyperglycemia (fasting plasma $glucose{\geq}110mg/dl$), increases the cardiovascular risk of the general population. Recently, risk of this syndrome arises in young adults world widely. Therefore, we randomly selected and evaluated the risk of metabolic syndrome of total 43 people (group I-22, group II-21) for 2 years. Group I was 22 peoples (15 males, 7 females) with age of 22 thru 35 year old (average 28 year old) and group II was 21 people (19 male, 2 female) with age of 22 thur 32 years old (average 24 year old) in Cheongju area from March 1st thru 30th of 2008 in Cheongju area from September 1st thru 30th of 2007 in order to find out how serious this phenomenon is in young adult of Korea. 13.95% (n=7) of total people has a metabolic syndrome by NCEP/ATPIII definition among this group (group I-6, group II-1). Those of 6 have 3 or over risk factor for metabolic syndrome such as obesity, hypertension, fasting blood glucose and hypetriglyceridemia at the same time (group I-5, group II-1). Group I have more risk factor because of more higher age than group II. Therefore we need aggressively to monitor and provide them for early diagnosis, educational programs and assistance for lifestyle changes in order to prevent metabolic syndrome among young adults.

Objectives: Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Methods: Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

Cathepsin D (CtsD)는 아스파르트산 단백질 분해효소로서 cytochrome C의 방출을 유도하여 apoptosis 기전을 활성화시킨다. 본 연구에서는 3T3-L1 지방전구세포에서 CtsD 발현 조절에 관여하는 microRNA에 대해 조사하였다. 먼저 지방전구세포 사멸시 CtsD 발현 변화를 관찰하기 위하여 DNA damage agent인 doxorubicin을 3T3-L1 세포주에 노출시켜 CtsD 발현이 증가함을 확인하였다. 또한 지방전구세포주에서 CtsD가 과발현되면 세포 생존율이 감소하였다. miRanda program을 이용하여 CtsD 유전자를 표적으로 하는 microRNA를 탐색하여 miR-145를 선발하였다. Luciferase reporter assay에 의해 miR-145가 CtsD 유전자의 3' UTR 부위에 결합하여 luciferase 활성을 감소시킴을 관찰하였다. 3T3-L1 세포주에 miR-145 mimic을 도입한 결과 CtsD mRNA 발현과 단백질 수준이 감소하였다. 또한 세포주에 doxorubicin을 처리한 결과 CtsD 유전자 발현 증가와 상반되게 miR-145 발현이 감소하였다. 이외에도 miR-145 inhibitor을 세포에 도입하면 세포 생존율이 감소하였다. 이러한 결과는 지방전구세포의 세포사멸에 CtsD가 관여할 수 있으며, miR-145에 의해 CtsD 발현이 직접 조절되고 있음을 나타낸다. 따라서, 지방전구세포의 사멸을 유도하기 위해서는 miR-145 발현 제어가 주요한 표적이 될 수 있을 것으로 생각된다. 본 연구결과는 향후 비만 예방 및 치료를 위한 지방세포 사멸기전 규명에 중요한 기초 자료를 제공할 수 있을 것으로 기대한다.

항암제로 알려진 cisplatin과 t-BHP를 토끼에 투여하여 유도된 급성 신부전 시 산조인 추출액을 처리하였을 때 신장 세포의 보호에 미치는 항산화 효과를 조사하였다. 신장을 분리한 후 신피질 절편 실험에서 세포의 손상을 유발하는 지질과산화 및 LDH 실험에서 t-BHP 단독 처리 시 대조군에 비하여 각각 3배, 5배 이상 증가하였으나 산조인 추출액 0.5%를 동시 처리하였을 때는 대조군 수준으로 감소하였다. Creatinine 측정과 지질과산화 실험에서 cisplatin $5mg{\cdot}kg^{-1}$을 복강 투여한 군의 creatinine 농도가 $2.13{\pm}0.1mg{\cdot}dl^{-1}$로 나타났으나 산조인 추출액 $50mg{\cdot}kg^{-1}{\cdot}day^{-1}$을 7일간 전처리 후 cisplatin 투여 48시간 경과한 군은 $0.84{\pm}0.1mg{\cdot}dl^{-1}$로 creatinine의 농도가 약 60% 감소되는 신장보호 효과를 나타내었고, 지질과산화 검사는 cisplatin 단독 투여 시 대조군에 비하여 1.6배 높게 나타났으나 산조인 추출액 전처리 시 1.1배로 대조군과 유사하였다. 병리조직 검사는 cisplatin 단독 처리군에서 근위곱슬세관이 대조군에 대하여 더 붉게 염색되었으며 근위곱슬세관은 내강의 융모세포가 탈락하여 공포를 형성하였다. 그러나 산조인 추출액을 7일간 전처리한 군에서는 근위곱슬세관이 대조군과 유사한 염색소견을 보였고 근위곱습세관도 내강의 융모세포 탈락이 거의 나타나지 않았다. 따라서 cisplatin과 t-BHP에 의해 유발된 신장세포 손상에 대하여 산조인 추출액이 항산화 효과를 보였다.

Korean dishes, Hansik are characterized by healthful vegetable intake. The purpose of this study was to evaluate the inhibitory effect of commonly consumed vegetables by Koreans on obesity/metabolic disease-related inflammation. Through statistical analysis of the KNHANES database ($1^{st}$ 1998, $5^{th}$ 2010, 2011) and a literature review, we selected vegetables for study. Among the vegetables, main or sub ingredients of Kimchi were excluded. Samples were prepared using only edible portions and freeze-dried. After grinding, samples were extracted with ethanol, evaporated and finally lyophilized. The cytotoxicity of samples was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, at various concentrations that do not affect cell viability. Raw 264.7 macrophages were treated with lipopolysaccharide (LPS) and 11 kinds of samples or positive control (troglitazone) dissolved in dimethyl sulfoxide (DMSO). After 24 hours, nitric oxide (NO), tumor necrosis factor ${\alpha}$ (TNF-${\alpha}$) and monocyte chemoattractant protein-1 (MCP-1) production were determined. Excepts for young pumpkin and bracken, nine samples effectively reduced NO production compared with control treated with LPS and DMSO. NO levels of five samples (bean sprouts, leeks, eggplant, mugwort, and pumpkin) were similar to that of the positive control. These five samples showed significantly decreased TNF-${\alpha}$ or MCP-1 compared to the control group. Our results suggest that consumption of commonly consumed vegetables contributes to partial prevention of obesity and related metabolic syndrome through reduction of NO, TNF-${\alpha}$, and MCP-1 production.

This study was performed to determine the health and nutritional risk factors associated with hypertension in Koreans over the age of 50 in a high-income class (more than twice as much family income as the 2005 Korean minimum cost of living, 668,540 Won). A total of 505 subjects aged over 50 from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) were divided into two groups: A hypertension group (HG) (N=151, Systolic Blood Pressure ${\geq}$140 mmHg or Diastolic Blood Pressure ${\geq}$90 mmHg) and normal group (NG) (N=354). Subjects who took hypertension medicines or underwent diet therapy were excluded. In HG, mean daily alcohol intake and the amount of alcohol consumption per one occasion were significantly higher than in NG, respectively. A greater number of hypertension subjects answered that they drank alcohol to reduce stress as compared to normal subjects. HG also took fewer dietary supplements than NG. Mean body mass index (BMI), waist circumference, fasting blood sugar level, and 2 hour postprandial blood sugar following a glucose load were significantly higher in HG than in NG, respectively. Also, iron, thiamin, and niacin intakes and the consumption frequency of seaweeds were significantly lower in HG than in NG, respectively. Finally, obesity (BMI ${\geq}$25 $kg/m^2$), abdominal obesity (waist circumference ${\geq}$90 cm for males, ${\geq}$ 80 cm for females), high blood sugar level 2 hours after an oral glucose load (${\geq}$140~200 mg/dl), and hypertriglyceridemia (serum TG ${\geq}$200 mg/dl) were related to a significantly higher risk of hypertension in the subjects (odds ratio: 1.884~3.040). In conclusion, dietary factors such as higher alcohol consumption; lower intakes of iron, thiamin, and niacin; lower consumption frequency of seaweeds; and metabolic syndrome were associated with hypertension in the study subjects.

With the aim of diagnostic research on health education. the health promoting behaviors related to elementary school students' weight control. life satisfaction. health state. self-efficacy. parent's interest and knowledge about weight control and school health education of weight control were investigated on the basis of the PRECEDE model. The data for this study were collected from a sample at an elementary school in Chongju for 5 days in July. 2004. In analyzing the data. t-test. one-way ANOVA. chi-square test and multiple regression analysis were done by using SPSS 10.1 The results were as follows : 1. The elementary school students' level of life satisfaction was above half of the full point. The score difference of life satisfaction was statistically significant by grade and academic achievement(F=4.646. p=.010. F=16.042. p=.000). 2. The perceived level of health state was moderate for all students. Normal weight students' level was significantly higher than obese students' (t=3.667. p=.000). 3. The perceived level of health promoting behaviors related to weight control was above the moderate. The perceived level of health promoting behaviors related to weight control in the obese students was significantly higher than that in normal weight students(t=-2.225. p=.027). The students used computer for 1.48 hours and watched TV for 2.52 hours a day. 4. The score of health promoting behavior self-efficacy in this subject was 70.61. 5. The parents' level of interest in the obese students' weight control was significantly higher than that in the normal weight students(t=-4.86. p=.000). 6. Sixty-six percent of the students learned about weight control education in school. 7. The health promoting behavior self-efficacy among the educational diagnostic variables was the most influential variable in students' health promoting behaviors related to weight control. This research diagnosed the needs of weight control education in elementary school by assessing various factors related to weight control behaviors. The research findings suggest that we can enhance the prevention of childhood obesity by strengthening the related factors such as parents' knowledge and interest, health promoting behaviors and self-efficacy related to weight control in school health education.

Objectives We evaluated the improving effects of Taeksa-tang (TST) using 3T3-L1 cells and C57BL/6 mice were fed on a high-fat diet. Methods The anti-radical activities of TST were studied using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The content of total polyphenol was measured using Folin-Ciocalteu reagent, whereas aluminum chloride colorimetric method was used for the content of total flavonoid. Moreover, the factors related to lipid profile and the protein expressions such as 𝛽-oxidation and anti-oxidant enzyme were analyzed using serum and western blotting of 3T3-L1 cells. Additionally, we examined lipolysis through glycerol appearance in mouse adipose tissue. Results TST treatment showed strong free radical scavenging activities with half maximal inhibitory concentration and the presence of a amount of total polyphenol and total flavonoid. TST treatment significantly increased factors related to 𝛽-oxidation such as carnitine palmitoyl transferase-1 and uncoupling protein 2 via the phosphorlyation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK). Moreover, the protein expressions of anti-oxidant enzyme and lipolysis were significantly elevated by TST administration. In addition, TST supplementation lowered serum malondialdehyde, triglyceride, and total cholesterol levels compared with the control group. Taken together, these data suggest that TST treatment regulated lipid parameters via the increase of 𝛽-oxidation by LKB1-AMPK signaling pathway. Conclusions TST may have a potential remedy in the prevention and treatment of obesity. Therefore, this study may provide the scientific basis for TST use.
