Recently, dietary pattern analysis was emerged as an approach to examine the relationships between diet and risk of chronic diseases. This study was to identify groups with population who report similar dietary pattern in Korean genome epidemiology study (KoGES) and association with several chronic diseases. The cohort participants living in Ansung and Ansan (Gyeonggi province) were totally 10,038. Among those, 6,873 subjects with no missing values in food frequency questionnaire were included in this analysis. After combining 103 food items into 17 food groups, 4 dietary factors were obtained by factor analysis based on their weights. Factor 1 showed high factor loadings in vegetables, mushrooms, meats, fish, beverages, and oriental-cereals. Factor 2 had high factor loadings in vegetables, fruits, fish, and factor 3 had high factor loadings in cereal-oriental, cerial-western and snacks. Factor 4 showed positive high factor loadings in rice and Kimchi and negative factor loadings in mushrooms and milk and dairy products. Using factor scores of four factors, subjects were classified into 3 clusters by K-means clustering. We named those 'Rice and Kimchi eating' group, 'Contented eating' group, and 'Healthy and light eating' group depending on their eating characteristics. 'Rice and Kimchi eating' group showed high prevalence in men, farmers and 60s. 'Contented eating' group and 'Healthy and light eating' group had high prevalence in women, people living in urban area (Ansan Citizen), with high-school education and above, and a monthly income of one million won and more. 'Contented eating' group appeared lower distribution proportion in the sixties and 'Healthy and light eating' group does higher in the fifties. 'Contented eating' versus 'Rice and Kimchi eating', odds ratio for hypertension, diabetes, metabolic syndrome and obesity significantly decreased after adjusting age and sex (OR=0.64, 0.73, and 0.85 respectively, 95% CI). Although our results were from a cross-sectional study, these imply that the dietary patterns were related to diseases.

BACKGROUND/OBJECTIVES: Endoplasmic reticulum (ER) stress is positively associated with atherosclerosis via elevating macrophage cell death and plaque formation, in which oxidative stress plays a pivotal role. Antioxidative, lipid-lowering, and anti-atherogenic effects of kimchi, a Korean fermented vegetable, have been established, wherein capsaicin, ascorbic acid, quercetin, 3-(4'-hydroxyl-3',5'-dimethoxyphenyl)propionic acid, and lactic acids were identified. In this study, mechanisms of action of kimchi methanol extracts (KME) on fatty streak formation via suppression of ER stress and apoptosis in aorta were examined in low-density lipoprotein receptor knockout mice. MATERIALS AND METHODS: Mice fed a high cholesterol diet with an oral administration of KME (KME group, $200 mg{\cdot}kg-bw^{-1}{\cdot}day^{-1}$) or distilled water (control group) for 8 weeks (n = 20 for group). Plasma lipid and oxidative stress levels were evaluated. Protein expression was measured by western blot assay. Fatty streak lesion size and the degree of apoptosis were examined in the aorta. RESULTS: Compared to the control group, in the KME group, plasma lipids levels were decreased and oxidative stress was alleviated (P < 0.05). Protein expression levels of nuclear factor (erythroid-derived 2)-like 2-mediated antioxidants in aorta were increased whereas those for ER stress markers, glucose regulated protein 78, phospho-protein kinase RNA-like ER kinase, phospho-eukaryotic initiation factor 2 subunit ${\alpha}$, X-box binding protein 1, and C/EBP homologous protein were decreased in the KME group (P < 0.05). Moreover, apoptosis was suppressed via downregulation of phospho-c-Jun N-terminal kinase, bcl-2-associated X protein, caspases-9, and -3 with a concomitant upregulation of anti-apoptotic protein, B-cell lymphoma 2 (P < 0.05). Fatty streak lesion size was reduced and the degree of apoptosis was less severe in the KME group (P < 0.05). CONCLUSIONS: In conclusion, antioxidant activity of KME might prevent fatty streak formation through, in part, inhibition of ER stress and apoptosis in aortic sinus where macrophages are harbored.

The prevalence of type 2 diabetes mellitus has been rapidly increased in parallel with the westernization of eating behavior in Korea. Increased consumption of animal fat and simple sugar can be potential contributors for insulin resistance. The purpose of the study was to determine whether Western-(WD) and Korean-style(KD) diets altered insulin secretion and insulin resistance in male Sprague Dawley rats. Rats weighing 98$\pm$5g were provided by KD(77 En% of starch, 5 En% of corn oil and 13 En% of gluten plus 5 En% of casein), WD(42 En% of starch, 40 En% of butter and 18% of casein) or control diet(62 En% of starch, 20 En% of corn oil and 18% of casein) for 12 weeks. Body weights were lower in KD compared to WD. Fasting blood glucose levels were not different among diets. Insulin secretion from the beta cells was higher by 2.2$\pm$0.4 folds in WD than KD at baseline. In hyperglycemic clamp insulin secretion was higher in WD than KD and CD. Whole body glucose disposal rates referred to the state of insulin sensitivity were lowest in WD among groups. Glycogen deposits in soleus and quadriceps muscles were lowest in WD among all groups, but their triglyceride contents were highest. GLUT4 contents and glycogen synthase were lowest in WD in both muscles. In conclusions, westernization of diets needed more insulin to normalization of blood glucose levels due to increased insulin resistance. Thus, WD would lead to increased prevalence of diabetes mellitus when increased insulin resistance could not be compensated by insulin secretion in the case of elevated blood glucose levels.

Peroxynitrite ($ONOO^-$), superoxide anion radical (${\cdot}\;{O_2}^-$) and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging processes, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer, diabetes, obesity and atherosclerosis. The aim of this study was to investigate the effects of Ojunghwan on the generation of peroxynitrite ($ONOO^-$), nitric oxide (NO) and superoxide anion radical (${\cdot}\;{O_2}^-$), and on the expression of $NF-{\kappa}B$-dependent inflammatory proteins in ob/ob mice. Mice were grouped and treated for 5 weeks as follows. Both the normal lean (C57/BL6J black mice) and control obese (ob/ob mice) groups have received the standard chow. The experimental groups were fed with a diet of chow supplemented with 30 and 90 mg Ojung-hwan per 1 kg of body weight for 14 days. For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Western blot was performed using anti-phospho $I{\kappa}B-{\alpha}$, $anti-IKK-{\alpha}$, $anti-NF-{\kappa}B$ (p50, p65), anti-COX-2, anti-iNOS, anti-VCAM-1 and anti-MMP-9 antibodies, respectively. Ojunghwan inhibited the generation of $ONOO^-$, NO and ${\cdot}\;{O_2}^-$ in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondrial fraction in vitro. The generation of $ONOO^-$, NO, ${\cdot}\;{O_2}^-$ and $PGE_2$ were inhibited in the Ojunghwan-administered ob/ob mice groups. The GSH/GSSG ratio was decreased in the ob/ob mice, whereas that were improved in the Ojunghwan-administered groups. Ojunghwan inhibited the expression of $phospho-I{\kappa}B-{\alpha}$, $IKK-{\alpha}$, $NF-{\kappa}B$ (p50, p65), COX-2, iNOS, VCAM-1 and MMP-9 genes. These results suggest that Ojunghwan is an effective scavenger of $ONOO^-$, ${\cdot}\;{O_2}^-$, NO and $PGE_2$, and has an inhibitory effect on the expression of $NF-{\kappa}B$-dependent inflammatory genes in ob/ob mice. Therefore, Ojunghwan might be used as a potential therapeutic drug against the inflammation process and inflammation- related diseases.

Recent studies determined that a chronic western-style diet increased the endogenous small heterodimer partner (SHP) protein levels in mice. In experiments with cell cultures, chenodeoxy cholic acid (CDCA) treatment increased endogenous SHP protein levels and reduced the degradation rate of exogenously expressed flag-SHP levels in the human hepatoma cell line, HepG2 cells. In addition, bile acid-induced intestinal fibroblast growth factor-19 (FGF-19) increased the half-life of the exogenously expressed SHP when HepG2 cells were transfected with ad-flag-SHP. However, both the expression level and the degradation rate of the endogenous SHP in response to cholic acid and FGF-19 have not been well understood, either in mice or in cultured HepG2 cells. This study examined the effects of cholic acid treatment on the endogenous SHP protein levels in mice and the effects of FGF-19 on the degradation rate of the endogenous SHP protein in HepG2 cells. Mice fed 0.5% cholic acid in normal chow showed an increase in endogenous SHP protein levels during both 12 hr and 24 hr treatment periods as compared to control mice fed only normal chow. In cultured HepG2 cells, treatment with CDCA did not noticeably change the rate of degradation in the endogenous SHP protein from cells not treated with CDCA. Although consistent with the previous studies on the exogenous ad-flag-SHP protein, treatment with FGF-19 significantly decreased the degradation rate of the endogenous SHP protein when HepG2 cells were treated with cyclohexamide. These results suggest that both bile acids and FGF-19 increase the endogenous SHP protein levels in mouse liver and HepG2 cells.

Recently, change of Western pattern diet and lifestyle is caused by various metabolic disorders and chronic diseases. These diseases need to take medicine regularly. Also, many people take health functional food, various vitamins and nutritional supplements in order to maintain a healthy life. But, there was no study about affects taking medicines against bacteria with gastrointestinal relevance. This study was performed by antibacterial activity test to evaluate the influence of a long time or commonly used medication. As a result, medicines of Vitamins & Minerals or Central nervous system show antibacterial activity against beneficial enteric bacteria and harmful enteric bacteria. Dexibuprofen of the Anti-inflammatory Drugs that acts on the central nervous system has shown high antibacterial activity at beneficial enteric bacteria strains (Lactobacillus casei, Lactobacillus rhamnosus) and harmful enteric bacteria (Staphylococcus aureus). Also, fenofibric acid of the antilipemic agents that acts on the Cardiovascular & Hematopoietic system has shown high antibacterial activity at beneficial enteric bacteria strains (Lactobacillus casei). Vitamins & Minerals appeared antibacterial activity against most intestinal bacteria. Vitamin B-Complex/with C and vitamin C were especially high with beneficial enteric bacteria strains (Bifidobacterium infantis) and harmful enteric bacteria (E. coli, E. aerogenes, S. flexneri, S. Typhimurium, S. aureus). Therefore, these results indicate that variously taking medicines have generally antibacterial activity against harmful enteric bacteria strains and beneficial enteric bacteria strains.

The pigments of three old and new celestial charts folding screens(『Celestial Chart(Folding Screen)』 and 『Old and New Celestial Charts, Eight-Panel Folding Screen』 of National Folk Museum of Korea and 『Koudou-Nanboku-Ryousouseizu』 of National Diet Library of Japan) were analyzed to estimate their dating. It was estimated that the 『Celestial Charts(Folding Screen)』 was painted using traditional pigments from the Joseon dynasty such as azurite, indigo lake, malachite, atacamite, vermilion, iron oxide, cochineal, gamboge, orpiment, lead white, talc and soot. The green and blue colors of the 『Old and New Celestial Charts, Eight-Panel Folding Screen』 and 『Koudou-Nanboku-Ryousouseizu』 were painted using artificial inorganic pigments such as emerald green and ultramarine blue. These pigments were imported from Europe post the mid-19th century. In the 『Old and New Celestial Chart, Eight-Panel Folding Screen』, only artificial inorganic pigments were used for green and blue colors. However in the 『Koudou-Nanboku-Ryousouseizu』, emerald green and atacamite in green color, and ultramarine blue and indigo lake in blue color were used together. Based on both the results of pigment analysis and the study of star charts and inscriptions, the 『Celestial Charts(Folding Screen)』 was painted post mid-18th century. The 『Koudou-Nanboku-Ryousouseizu』 and 『Old and New Celestial Charts, Eight-Panel Folding Screen』 were painted after green and blue artificial pigments were imported in the mid-19th century. The 『Koudou-Nanboku-Ryousouseizu』 in which both traditional and western artificial pigments were used, can be dated earlier than the 『Old and New Celestial Chart, Eight-Panel Folding Screen』.

This study, targeting the students of "K" university in Busan City area, was performed to draw the groups by food-related lifestyle types and to identify the correlation between each group's attributes of selecting places to eat out and obesity index. The purpose of the study was achieved by means of the PASW Statistic 18.0(Predictive Analytics Software) which conducted frequency analysis, factor analysis, reliability analysis, t-test, ${\chi}^2$-test, non-hierarchical cluster analysis and ANOVA. It turned out that the male university students were 175.59 cm tall and weigh 69.53 kg on average. And the female university students showed their average height of 162.81 cm and weight of 53.42 kg. When examined by the body mass index(BMI), male students were composed of 1.7% of underweight, 64.6% of normal weight, 19.7% of overweight and 14.0% of obese. As for the female students, 22.9% were classified as underweight, 62.7% as normal weight, 8.5% as overweight and 5.9% as obese. The food-related lifestyle categories were divided into five factors; health seeking type, safety seeking type, mood seeking type, taste seeking type, and western food seeking type. The four attributes of selecting places to eat out included quality of food and service, price reasonableness, accessibility and atmosphere, and experience to have eaten. With regard to food-related lifestyle, the groups were named by cluster 1 [careless diet group], Cluster 2 [health oriented group], and cluster3 [careless healthcare group]. In terms of the correlation between the clusters by food-related lifestyle and their attributes of selecting places to eat out, Cluster 1 had a high mean value in experience to have eaten, Cluster 2 quality of food and service, Cluster 3 accessibility and atmosphere.

The research on the actual condition of the oriental health related industry has been made with defining it's phase. As a result, I have come to develope korean-type health model, which can solve the problems derived from the past herb medicine industry. The prospects and roles of the oriental health related industries are as follows: The phase adjustment of the oriental health related industry. The problems of modern medical science happens in the beginning of 21st century, the importance of oriental health improvement in the field of health business is now being on the rise. therefore it is necessary to readjust the present status of the oriental medicine and to take it into health area. Should the responsible institutes regarded on oriental medicine make clear prescription in terms of oriental health industry's role and limitation, they could contribute health circumstance in the 21st century. This is because oriental health related industry can be utiliged in not only protective area and curable area. The present situation of the oriental health related industry. These herb medical societies are flooded with various oriental health industry apart from the legal systematic control so far health industry apart from the legal systematic control so far. The expected survey can not be complete but random under these situations. Nevertheless oriental medical health industry area such as a diet cure, exercise treatment and living condition cure are being considerably expanded, especially living facilities improvement and mind control areas are toward worldwide. Consquently herb health industries are now？ consistantly developed by the influence of western nature treatment stemmed from the oriental medicine theory. The role and prospect of the oriental health related industry in 21st century. The oriental health industries can be helpful for the human being's health improvement in general but by the lack of scholastic oriental health theory, it does not contribute to the health welfare. If these problems are made up for in the field of theory area, the oriental health related industry will surely have the potentiallity and know how for health welfare. The successive role of these industry is depended on the fact that the characteristics of the oriental medicine should adjust to the real society with the systematic management. In the 21C, oriental health industry will certainly be vitalized owing to the social and periodical request especially in the area of oriental medical industry, oriental health drink industry, oriental health mind exercise industry, oriental health leasure industry and oriental health complex management industry. Among these areas, it is the oriental health complex amagement industry that will be the limestone of prosperity of the oriental health industry in 21C. Proposal for the social contribution of the oriental health related industry in the 21C. To achive the ultimate role of the oriental health industry in the 21c, first we should know how to use the oriental medicine. Second We should make an effort to revitalize the oriental health industry. So it is indespensible that government, academic institution and enterprise should concentrate their interest on the oriental health industry with common knowledge and systematic management in advance.

Objectives: Peroxynitrite ($ONOO^-$), superoxide anion radical (${\cdot}{O_2}^-$ and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging processes, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer, diabetes, obesity and atherosclerosis. The aim of this study was to investigate the $ONOO^-$, NO, ${\cdot}{O_2}^-$ scavenging and NF-${\kappa}B$ related anti-inflammatory activities of Sotosaja-hwan in ob/ob mice. Methods: Mice were grouped and treated for 5 weeks as follows. Both the normal lean (C57/BL6J black mice) and control obese (ob/ob mice) groups have received standard chow. The experimental groups were fed with a diet of chow supplemented with 30 and 90 mg Sotosaja-hwan per 1 kg of body weight for 14 days. For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Western blotting was performed using anti-phospho-$I{\kappa}B$-${\alpha}$, anti-IKK-${\alpha}$, anti-NF-${\kappa}B$ (p50, p65), anti-COX-2, anti-iNOS, anti-YCAM-1 and anti-MMP-9 antibodies, respectively. Results: Sotosaja-hwan inhibited the generation of $ONOO^-$, NO and ${\cdot}{O_2}^-$ in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondrial fraction in vitro. The generation of $ONOO^-$, NO, ${\cdot}{O_2}^-$ and PGE2 were inhibited in the Sotosaja-hwan-administered ob/ob mice groups. The GSH/GSSG ratio was decreased in the ob/ob mice, whereas the ratio was improved in the Sotosaja-hwan-administered groups. Sotosaja-hwan inhibited the protein expression levels of phospho-$I{\kappa}B$-${\alpha}$, IKK-${\alpha}$, NF-${\kappa}B$ (p50, p65), COX-2, iNOS, YCAM-1 and MMP-9 genes. Conclusions: These results suggest that Sotosaja-hwan is an effective $ONOO^-$, ${\cdot}{O_2}^-$ and NO scavenger and has NF-kB related anti-inflammatory activity in ob/ob mice. Therefore, Sotosaja-hwan might be a potential therapeutic drug against the inflammation process and inflammation-related diseases.
