아직 분명히 규명되지 않은 부분이 많지만, 신선초가 다양한 측면에서 건강증진 효과가 있다고 믿어져 왔고 따라서 일반인들이 지금까지 사용해 오고 있다. 이 연구에서는 신선초의 메타놀 추출물을 투여한 후, 전형적인 간독성 유발물질인 갈락토사민과 사염화탄소를 투여한 랫드에서 일반적 간독성지표와 지질대사능 지표를 측정함으로써 간장 보호작용이 있는지 시험하였다. 신선초를 독성유발전 7일간 매일 1회씩 200 및 500mg/kg의 용량으로 경구투여 하고, 간독성물질을 복강내로 투여 한 후 독성유발 24시간에 혈장과 간장조직에 대한 분석을 수행하였다. 시험한 두 용량(200 및 500 mg/kg)은 갈락토사민에 의해 유발된 지질과 산화물 증가, 혈장 AST 및 ALT 활성의 증가를 감소시켰다. 또한 신선초 500mg/kg은 갈락토사민이 유발한 혈장 중성지질, 총 콜레스테롤 및 저밀도지단백 콜레스테롤의 농도 증가현상을 감소시켰다. 갈락토사민에 의해 유발된 독성에 대한 효과와는 달리, 사염화탄소로 유발된 AST, ALT 및 과산화지질의 증가현상이 신선초 전투여에 의해 더욱 증가하였다. 이 결과는 갈락토사민에 의한 독성을 신선초 전투여가 감소시킬 수 있지만, 반대로 사염화탄소 유발 독성은 더 악화시킴을 의미한다. 신선초의 사염화탄소 유발 간독성 증강효과에 대한 기전을 이해하기 위해 신선초를 투여한 랫드의 간장내 aninline hydroxyiase의 활성을 측정하였다. 그 결과 사염화탄소가 간독성을 발휘하는 데에 필요한 조건인 대사체로의 변환을 매개하는 이 효소의 간장내 활성이 증가함을 관찰하였다. 종합적으로 신선초가 간장보호효과를 발휘하지만 간독성이 어떤 독소에 의해 유발되었느냐에 따라 향상 보호효과가 있지는 않음을 의미한다.

Fatty liver disease refers to a range of disorders associated with fatty liver, which occur in excessive eating, evident infection or significant consumption of alcohol. This study was to investigate the effects of water and ethanol extracts of Triticum aestivum young leaf on lipid metabolism and accumulation in liver of mice fed with high-fat diet. Male C57BL/6 mice were divided into normal diet group, high fat diet (HFD) group, high fat diet group administrated with 200 mg/kg/day of T. aestivum water extract (HFD-TAWE) and high-fat group administrated with 200 mg/kg/day of T. aestivum ethanol extract (HFD-TAEE). TAWE and TAEE were administrated orally for 5 weeks once at the same time point. Both TAWE and TAEE significantly reduced body weight, food intake and liver tissue weight, which were augmented in high fat-fed mice. The serum levels of triglyceride, total and LDL-cholesterol also were significantly attenuated in both HFD-TAWE and HFD-TAEE groups compared to the HFD group. Moreover, administration of HFD-TAWE or HFD-TAEE reduced the lipid accumulation in liver tissue of mice fed with high fat diet. Levels of total lipids and triglyceride in liver tissues also was significantly reduced in HFDTAWE and HFD-TAEE groups compared to HFD group. The activities of serum ALT and AST revealed in HFD group were remarkedly decreased in HFD-TAEE groups. These results indicate that both water and ethanol extract of T. aestivum may improve the lipid accumulation in liver as well as lipid metabolism in serum, and that in particular, the ethanol extract of T. aestivum may has the potent anti-hyperlipidemic effect, suggesting that it may be a useful candidate for the therapy preventing fatty liver diseases.

배경: 에스트로겐이 동맥경화증의 진행을 억제하고 예방하는데 중요한 역할을 하는 것으로 알려졌으나 그 기전은 아직 명확하지 않다. 본연구에서는 에스트로겐이 혈관의 확장에 중요한 역할을 하고 있는 nitric oxide와 동맥경화에 어떠한 영향을 미치는지를 알아보고자 하였다. 대상 및 방법: 뉴질랜드종 웅성 가토 40마리를 실험동물로 하여 정상식이군(ND), 정상식이와 0.02ig의 estradiol-2 patch 투여군(END), 0.5% 콜레스테롤 투여군(CD), 0.5% 콜레스테롤 투여와 0.02 $\mu\textrm{g}$의 estradiol-2 patch 투여군 (ECD)의 네군으로 나누어 12주간 실험을 하여 혈중 estradiol-2, nitric oxide, cholesterol 등을 측정하고 흉부동맥과 복부동맥의 동맥경화 병변을 관찰하였다. 결과: 혈중 estradiol-2의 농도는 ED, ECD 군에서 ND, CD 군보다 의의 있게 높았다. (p<0.0001). 혈중 nitric oxide 농도는 정상 대조군 (ND)을 제외한 나머지 세군(END, CD, ECD)에서 모두 의의 있게 감소하였다.(p<0.001). 혈중 콜레스테롤은 총콜레스테롤, LDL콜레스테롤, HDL 콜레스테롤은 CD, ECD의 두 군에서 모두 증가하였으나 의의는 없었다(p<0.05). 혈중 콜레스테롤과 중성지방의 농도는 에스트로겐에 의한 영향이 관찰되지 않았다. 흉부 및 복부동맥의 동맥경화 병변은 ND군과 END군에서는 발생하지 않았으나 콜레스테롤을 투여한 CD군과 ECD군의 두 군에서 현저하게 발생하였으며 혈관별 발생정도의 차이는 없었다. 에스트로겐에 의한 병변의 발생 차이는 관찰되지 않았다. 광학현미경상 동맥경화병변은 거의 지방을 탐식한 대식구의 증식으로 이루어졌었으며, 괴사나 섬유화 병변은 관찰되지 않았다. 전자현미경상에서는 내피세포의 광범위한 손상이 관찰되었다. 병리학적으로 에스트로겐에 의한 영향은 인정하기 어려웠다. 결론: 고지방식은 혈중 nitric oxide의 생산을 크게 저하 시키며, 그 원인으로는 지방의 과산화에 의한 내피세포의 손상때문인 것으로 추정된다. 또한 estradiol-2 patch 처치에 의해서 nitric oxide가 감소된 것은 그이유를 설명하기 곤란하나 성차이 및 에스트로겐의 투여방법에 의한 어떤 영향이 있었을 것으로 추측된다. 피부를 통한 에스트로겐의 투여는 혈중 콜레스테롤이나 중성지방의 농도에 영향을 주지 못했으며, 동맥경화의 진행에도 영향이 없었다. 에스트로겐의 동맥경화에 주는 영향에 대해서는 지속적이고 광범위한 연구가 더 필요할 것으로 사료된다.

The nutrient intake and association between dish group intake and blood glucose and serum lipid level (TG, cholesterol, LDL and HDL) was analyzed among 3 groups: 452 subjects in normal blood glucose group (NG: fasting blood glucose < 100 mg/dL and 2 hours postprandial blood glucose < 140 mg/dL), 258 subjects in impaired fasting glucose group (IFG: fasting blood glucose 100~125 mg/dL and 2 hours postprandial blood glucose ${\geq}$ 140 mg/dL) and 101 subjects in diabetic group (DG: fasting blood glucose $\geq$ 126 mg/dL and 2 hours postprandial blood glucose ${\geq}$ 140 mg/dL). The data were obtained from the 2005 National Health and Nutrition Survey of Korea. The 811 subjects were adults aged 40~64 without dietary treatment. In nutrients intake, IFG was the highest and DG the lowest in both quantity and quality. DG, especially, had the lowest intake in carbohydrates, fiber, proteins, Ca, P, K, vitamins B1 and C, and consumed the highest amount of alcohol. In macronutrients distribution ratio, the DG diet showed a lower energy intake from carbohydrates but higher from fat than the NG diet, while IFG showed a higher energy intake from carbohydrates and lower intake from fat in supper out of 3 meals and snacks. IFG preferred salt-fermented foods and DG preferred soups, braised foods and kimchi compared to other groups. NG preferred multi-grain cooked rice and both IFG and DG preferred plain white cooked rice. Regarding the association between dish group intake and blood glucose, cooked rice, soups, salt-fermented foods and kimchi were significantly related to blood glucose. In blood lipids, steamed-foods, beverages and fruits were inversely related to the risk of developing type 2 diabetes, whereas cooked rice, stews, saltfer-mented foods, seasoned-fermented foods and seasoned vegetables were directly proportional to the risk of developing type 2 diabetes and related diseases. Therefore, it is beneficial to avoid rich, salty and fatty foods and heavy alcohol consumption for controlling blood glucose and blood lipids, while steamed foods, foods rich in fiber (like multigrain rice) as a staple, and fruits and teas are recommended for preventing or managing type 2 diabetes risks.

Gallstone composition has changed over the past decades in the Korean with a prominent increase in the prevalence of cholesterol gallstone. This trend is possibly due to the westernization of dietary habits. The purpose of this study was descriptive of GB patient's health related eating behaviors and nutrient consumption patterns. One hundred and six gallstone patients who have had cholecystitis surgery enrolled in this study. Anthropomertic indices, such as height, weight, waist circumference, and hip circumference were measured and calculated BMI and WHR. As the biomarker, TC, TG, LDL-C, HDL-C, FBG level and SBP/DBP were measured and analyzed the relationship with GB stone formation. The structured checklist of health related eating behavior and the semiquantitative food frequency questionnaire after pre-test was used in the face to face interview study. The mean age was $54.9{\pm}13.3$ and gallstone disease was more frequent in the fifties and sixties. Mean BMI was $24.3{\pm}2.8$ in males, and $23.4{\pm}3.9$ in females, the average of waist circumference was $91.1{\pm}7.0cm$ in males and females were $85.4{\pm}9.6cm$. The WHR of men and women was $0.93{\pm}0.0,\;0.90{\pm}0.1$, respectively. The obesity and overweight trend was observed in gallstone patients. The mean blood sugar was researched at $114.5{\pm}35.0mg/dL$. And the ratio of both symptoms DM and gallstone was 26.4%. The rate of dramatic eating repast was significantly higher in the females (p<0.01). Males tended to more frequently consume meat, of high fat content meats and greasy food consumption when eating out. The CPF ratio was 57:16.5:26.5. There was a significant positive correlation between WC and energy (r=0.252, p<0.05), carbohydrate (r=0.255, p<0.05) and niacin (r=0.227, p<0.05). In addition, carbohydrate were significantly correlatied with TC (r=0.230, p<0.05). BMI appeared positive in correlation of protein (r=0.201, p<0.05) and fat (r=0.205, p<0.05). These findings provide a little association that dietary habits are related with cholesterol gallstone formation.

Objective This study was designed to investigate the effects of Gamiygin-tang (GY) extract (GYE) and fermented solution (GYF) on body weight, serum lipid level and adipocyte differentiation in high fat diet-fed obese mice. Materials and Methods High fat diet-fed obese mice and 3T3-L1 adipocytes mice were treated with GYE and GYF and obesity related markers were assessed. A cytotoxicity assay was carried out by MTS assay. Inhibitory effects of GYE and GYF on adipocyte differentiation were carried out by Oil Red O staining. The effects of GYE and GYF on the expression of adipocyte differentiation regulatory factors, peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) and CCAAT/enhancer binding protein alpha (CEBP-${\alpha}$) were measured by real-time reverse transcriptase-polymerase chain reaction. The effects of GYE and GYF on the expression of adipocyte differentiation regulatory factors were also determined in relation to protein production/protein levels by western blotting. The anti obesity effects of GYE and GYF were measured in high fat-diet induced obese mice. Various factors were measured from the serum of the high fat-diet mice. Results Though GYE did not show toxicity at the concentration of 1mg/ml, GYF showed toxicity at the concentration of 1mg/ml. The GYE at 0.1 and 1mg/ml inhibited the differentiation of 3T3-L1 cells, and the GYF also inhibited the differentiation of 3T3-L1 cells. The effect of GYE on adipocyte differentiation factors including PPAR-${\gamma}$ and CEBP-${\alpha}$ was investigated and compared to the corresponding concentration levels of GYF. GYE and GYF both suppressed the RNA and protein levels of adipocyte differentiation factors. In the animal test both GYE and GYF reduced weight gain. GYE and GYF reduced blood cholesterol, TG and LDL levels. GYF better reduced blood cholesterol levels. Conclusions These results demonstrate that GYE and GYF exerts anti-obesity effect in 3T3-L1 cells and obese mice induced by high-fat diet.

Antioxidants such as vitamin C and E may play a preventive role in the development of cancer and coronary heart disease. The status of vitamins C and E may be affected by lifestyle habits such as smoking , drinking, and exercise. These habits can modify the dietary requirements of vitamin C and vitamin E. the purpose of this study was to determine whether Korean young healthy men and women consume vitamins C and E in sufficient quantities relative to their lifestyle habits. Among the participants in this study, 52% of the men and none of the women were smokers. ; 84% of all subjects drank alcohol more than once a week ; and the men exercised more often than the women. The concentrations of serum total , HDL-, and LDL- cholesterol were higher in the women than in the men, but the serum triglyceride concentrations were higher in the men than in the women. The men consumed less satuated fat than the women (p<0.05) . The daily intakes of vitamin C for the men and the women were 47.1mg and 65.6mg, respectively. On the other hand , the daily vitamin E intake was higher in the men (11.8mg) than women(6.9mg). The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and in no subjects were they below the minimum value of ranges. However, about 19% of male subjects and 10% of female subjects showed deficient status, although the mean serum vitamin C levels were normal . Lifestyle habits fo the sort mentioned above have little influence on the serum vitamin C and $\alpha$-tocopherol concentrations. The serum $\alpha$-tocopherol concentration had a positive correlation with total fat and alcohol consumption. The serum vitamin C concentration was positively associated with regular exercise, but it was negatively correlated with the number of cigarettes smoked. Meanwhile, the serum lipid persoxide concentration , the indirect index of oxidative stress, was influenced by certain variable such as body mass index , the number of cigarettes smoked , alcohol consumption, energy expenditure, vitamin C intake, and serum ${\gamma}$-tocopherol concentration. Serum lipid peroxide concentration was positively associated with body mass index, the number of cigarette smoked , serum triglyceride , and HDL-cholesterol concentration. In conclusion , the vitamin E requirements of the subjects were met by the Recommended Daily Allowance (RDA) regardless of lifestyle habits. However, serum vitamin C concentrations showed individual variation and was below the normal ranges. Smoking and exercise influenced serum vitamin C concentration. Therefore, a reevaluation of the requirements of vitamin C relative to lifestyle habits is necessary.

BACKGROUND/OBJECTIVES: College students are in a period of transition from adolescence to adulthood, in which proper dietary habits and balanced nutritional intake are very important. However, improper dietary habits and lifestyles can bring several health problems. This study was performed to investigate blood lipid profiles, blood aluminum and mercury in college students and the relationships among them. SUBJECTS/METHODS: The subjects were 80 college students (43 males and 37 females) in Gyeonggi-do. General characteristics, anthropometric measurements, blood pressure, blood lipids, SGOT, SGPT, and blood aluminum and mercury of the subjects were measured and analyzed, and their relationship was studied. RESULTS: The BMI was significantly higher in males, $23.69{\pm}3.20kg/m^2$, than in females, $20.38{\pm}2.37kg/m^2$ (P < 0.001). The blood pressure was significantly higher in males with $128.93{\pm}12.92mmHg$ systolic pressure and $77.14{\pm}10.31mmHg$ diastolic pressure compared to females with $109.78{\pm}11.97mmHg$ and $65.95{\pm}6.92mmHg$, respectively (P < 0.001). HDL cholesterol in males, $61.88{\pm}13.06mg/dl$, was lower than $64.73{\pm}12.16mg/dl$ in females, but other blood lipid levels were higher in males. Blood aluminum was significantly higher in males, $9.12{\pm}2.11{\mu}g/L$, than in females, $8.03{\pm}2.14{\mu}g/L$ (P < 0.05), and blood mercury was higher in males, $3.08{\pm}1.55{\mu}g/L$, than in females, $2.64{\pm}1.49{\mu}g/L$. The blood lipids showed positive correlation with obesity and blood pressure. CONCLUSIONS: The degree of obesity, blood pressure, triglycerides, and LDL cholesterol were higher in males, suggesting possible association with chronic disease incidence such as hyperlipidemia and hypertension. Thus, it is considered that a systematic health education is needed for college students, especially for males.

본 연구는 건강신념모형의 주요 변수와 고지혈증 환자의 건강행태와의 관계를 파악하여 고지혈증 환자의 건강행태를 촉진하고 더 나아가 만성질환 보건사업 및 교육프로그램을 계획하는데 기초 자료를 제공하고자 시도되었다. 자료는 2009년 07월부터 2010년 9월까지 총콜레스테롤이 240mg/dl 이상이고, 중성지방이 200mg/dl 이상으로 고지혈증을 진단받은 20세 이상의 성인 남녀 146명을 대상으로 구조화된 설문지를 이용하여 조사하였으며, SPSS WIN(14.0 한글판) 프로그램을 이용하여 Chronbach's alpha의 신뢰성 분석, 요인분석, 단변량 및 다변량 분석을 시행하였다. 본 연구의 결과는 다음과 같다. 첫째, 본 연구에서는 LDL-cholesterol, HDL-cholesterol, TG에 대한 인지수준 중 TG에 대한 인지가 가장 높았고, 3가지 모두를 인지한 경우는 28.08%였다. 또한 9가지 항목에 대한 고지혈증 지식수준은 9점 만점에 평균 6.51이었으며, 지식수준이 높을수록 건강행태수준도 높았다. 둘째, 요인분석을 통하여 10개의 건강행태를 2개 요인으로 재분류 하였다. 그 결과, 건강행태 요인 1은 '식이, 운동 습관 및 고지혈증 검사 및 관련 검사요인', 건강행태 요인 2는 '흡연, 음주 습관 및 고지혈증 치료 관련 요인'이었다. 건강행태 요인1에 유의한 관련성이 있는 건강신념변수는 심각성, 이득, 장애로 나타났고, 취약성은 상관 관계가 없는 것으로 나타났다. 각 신념 요인들과 건강행태 간의 상관되는 순서는 이득(r =.455), 심각성 (r=.38), 장애(r=-.244) 순으로 나타나 고지혈증에 대한 이득 인식이 건강행태 요인1과 가장 관련성이 높은 것으로 파악되었다. 그러나, 건강행태 요인2는 건강신념변수와 관련성이 없는 것으로 나타났다. 셋째, 행동계기에 따른 건강행태의 관계를 살펴보면, 교육을 받았을 때 건강행태 요인1과 요인2에 모두 유의한 차이를 보이는 것으로 나타나, 교육이 고지혈증 환자의 건강행태에 중요한 영향을 미치는 것을 보여 주었다. 넷째, 다중회귀분석 결과 고지혈증 건강행태 요인1에 영향을 미치는 요인 중 유의한 요인으로 인지된 심각성 및 이점 신념요인, 교육여부, 보건소 교육정도 이었다. 건강행태 요인2에서는 성별, 연령, 교육여부가 유의한 영향을 미치는 요인으로 나타났다. 이상의 결과를 종합하면 건강신념모형이 고지혈증 건강행태를 예측하는데 적합한 모형이라고 판단 할 수 있으며, 건강행태 요인 특성에 따라 건강신념변수 중 고지혈증 예방에 대한 이득을 높이 인식할 수 있도록 프로그램과 교육목표를 설정하면 보다 효과적인 교육이 될 것이라 생각된다.
