Purpose: The current study was conducted in order to develop the Korean Healthy Eating Index (KHEI) for assessing adherence to national dietary guidelines and comprehensive diet quality of healthy Korean adults using the 5th Korea National Health and Nutrition Examination Survey (KNHANES) data. Methods: The candidate components of KHEI were selected based on literature reviews, dietary guidelines for Korean adults, 2010 Dietary Reference Intakes for Koreans (2010 KDRI), and objectives of HP 2020. The associations between candidate components and risk of obesity, abdominal obesity, and metabolic syndrome were assessed using the 5th KNHANES data. The expert review process was also performed. Results: Diets that meet the food group recommendations per each energy level receive maximum scores for the 9 adequacy components of the index. Scores for amounts between zero and the standard are prorated linearly. For the three moderation components among the total of five, population probability densities were examined when setting the standards for minimum and maximum scores. Maximum scores for the total of 14 components are 100 points and each component has maximum scores of 5 (fruit intakes excluding juice, fruit intake including juice, vegetable intakes excluding Kimchi and pickles, vegetable intake including Kimchi or pickles, ratio of white meat to read meat, whole grains intake, refined grains intake, and percentages of energy intake from carbohydrate) or 10 points (protein foods intake, milk and dairy food intake, having breakfast, sodium intake, percentages of energy intake from empty calorie foods, and percentages of energy intake from fat). The KHEI is a measure of diet quality as specified by the key diet recommendations of the dietary guidelines and 2010 KDRIs. Conclusion: The KHEI will be used as a tool for monitoring diet quality of the Korean population and subpopulations, evaluation of nutrition interventions and research.

In this study the sensitivity subjected to housing environmental as well as actual life and subjected to dietary living using experimental mice were investigated. In order to invest sensitivity for dietary life of the mice, using the dropwort(MINAISU) juice and the fermented with the extracted dropwort for change of weight on the mice, this was examined. The result of thus, group of infection through the mouth on dietary treatment for the high-fat foods and the dropwort more than compared with group of dietary treatment for the high-fat foods tended to be decreased. On fermented secretion group of the dietary treatment total cholesterol number also was decreased, the concentration of HDL cholesterol was shown a slight increased. The result of studying for the sensitivity controlled architectural structural material for the mice, coming under wooden living environment, making appearance with increasing weight as well as taking food and drink for psychological rest was considered. To examine changing weight through the mice in regard to the sensitivity for dietary life and living environment, in connection with promotion of health as well as diseases control the caused by those, would be achieve new balanced growth on basic study. Also that would be anticipated to making good use of thus results.

The purpose of this study was to explore dietary attitude among middle school students by sex. The subjects were collected from 211 boy students and 198 girl students in the city of Kunsan, Jeonbuk province. The mean age of the subjects was 13.7 years old. The average score of food habit was 4.61 $\pm$ 1.92. The average score of food habit of boy students was higher than the score of girl students. The correlations between the score of food habit and father's education level. family income, and nutritional supplements were positive. The correlation between the scores of the nutrition knowledge and father's education level was also positive. On the other hand the mother's occupation did not have any influence on the scores of food habits and the scores of the nutrition knowledge. As a staple food, cooked rice was preferred on boy and girl students at breakfast(82.7%) and supper(94.3%). The preference of snacks was fruit and fruit juice. The reason of skipping breakfast was the lack of time and no appetite, and skipping lunch was due to no appetite. Lastly the main reason of skipping supper was playing computer on boys. on the other hand no appetite and weight control on girls. In order to improve the nutritional status of the middle school students, they must establish good food habits by eating three regular meals per day and balancing their diet. Also they should be notified that severe weight control is very harmful for health. This study indicate that nutrition education and correct information for body image. balanced diet. regularity of meals and food selection are required for middle school students at both school and home.

This study aimed to investigate the physiological characteristics and anti-obesity effects of Lactobacillus plantarum K10. The ${\alpha}-amylase$ inhibitory activity, ${\alpha}-glucosidase$ inhibitory activity, and lipase inhibitory activity of L. plantarum K10 was $94.66{\pm}4.34%$, $99.78{\pm}0.12%$, and $87.40{\pm}1.41%$, respectively. Moreover, the strain inhibited the adipocyte differentiation of 3T3-L1 cells ($32.61{\pm}8.32%$) at a concentration of $100{\mu}g/mL$. In order to determine its potential for use as a probiotic, we investigated the physiological characteristics of L. plantarum K10. L. plantarum K10 was resistant to gentamycin, kanamycin, streptomycin, ampicillin, ciprofloxacin, tetracycline, vancomycin, and chloramphenicol. It also showed higher Leucine arylamidase, Valine arylamidase, and ${\beta}-galactosidase$ activities. Moreover, it was comparatively tolerant to bile juice and acid, exhibiting resistance to Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus with rates of 90.71%, 11.86%, 14.19%, and 23.08%, respectively. The strain did not produce biogenic amines and showed higher adhesion to HT-29 cells compared to L. rhamnosus GG. As a result of the animal study, L. plantarum K10 showed significantly lower body weight compared to the high-fat diet group. The administration of L. plantarum K10 resulted in a reduction of subcutaneous fat mass and mesenteric fat mass compared to the high-fat diet (HFD) group. L. plantarum K10 also showed improvement in gut permeability compared to the HFD positive control group. These results demonstrate that L. plantarum K10 has potential as a probiotic with anti-obesity effects.

The objective of this study was to assess the reliability and validity of food security measures, which was developed based on the US household food security survey module (US HFSSM) with content validity in the Korean population. The reliability and validity were assessed by internal consistency, construct validity and criterion-related validity. The study included 446 households. Among those, 46.2% were households with children. The proportion of food insecure households was 33.3%. Among those, 35.4% and 64.6% households were food insecure with hunger and without hunger, respectively. The Cronbach's alpha coefficients were 0.84 and the infit value by the Rasch model analysis ranged from 0.68 to 1.43. The scale item response curves by food insecurity severity explained well the nature and characteristics of food security, indicating the highest proportion of "yes" for the items on diet quality, followed by those with diet quantity. The result of criterion-related validity showed that food insecurity status was significantly related in a dose-response manner with the household income level, food expenditure, subjective health state, subjects' educational level. Household food security status was also related to dietary diversity regarding protein foods, fruits and fruit juice, and milk and dairy product. These findings suggest that the food security instrument is reliable and valid and would be used to assess food security status in the Korean population.

Consumption of high fat diet (HFD) induces obesity by accumulating triglycerides and inflammation in the body. In the present study, we investigated the effects of black onion vinegar (BV) on HFD-induced C57BL/6 obese mice model. The HFD-fed obese mice were administered black onion juice (BJ) and BV, respectively, for 6 weeks. The HFD-fed group increased body and organ weights compared with normal control diet-induced group. However, administration of BV significantly reduced body and organ weights compared with HFD-fed group. The BJ- and BV-administered groups improved the serum lipid profiles such as total cholesterol and triglyceride, compared with HFD-fed group. In addition, BV-administered group significantly improved serum high-density lipoprotein cholesterol and low-density lipoprotein cholesterol. The BV-administered mice had increased the number and size of adipose cells in the liver and adipose tissues. The administrations of BJ and BV significantly down-regulated adipogenesis transcription factors and proinflammatory proteins in the liver compared with HFD-fed group. In particular, BV-administered group showed stronger attenuation of adipogenesis-related proteins than the BJ-administered group. Therefore, this study demonstrated that administration of BV attenuated HFD-induced obesity, in particular down-regulation of adipogenesis, and it could be developed as a functional vinegar for anti-obesity.

The effect on serum lipid of green aster juice blended with ginseng and carrot extracts was investigated using rats injected with $CCl_4$. The rats were classified with four groups: (i) normal control (NC), (ii) rats fed with the blended juice (BA), (iii) rats treated with $CCl_4$ after having been on a normal diet for 4 weeks ($NC-CCl_4$), and (iv) rats treated with $CCl_4$ after having been fed the blended juice for 4 weeks ($BA-CCl_4$). All groups had similar feed intake. The weight gains and feed efficiency ratio were lower in the $NC-CCl_4$ group. The liver weight per body weight was much higher in the $NC-CCl_4$ group than the NC group, but did not differ between the $BA-CCl_4$ and BA groups. Triglycerides increased only for the $NC-CCl_4$ group (88.72 mg/dL); the other groups had similar levels (56.48-65.33 mg/dL). The BA group had the lowest total cholesterol level (74.08 mg/dL) the other groups had similar levels (96.78-108.83 mg/dL). HDL-cholesterol was lower in the $NC-CCl_4$ group (40.56 mg/dL) compared with the NC group (48.95 mg/dL), but there was no difference between the BA and $BA-CCl_4$ groups. The LDL-cholesterol level was higher in the $NC-CCl_4$ group (55.20 mg/dL the highest level) than the NC group (43.33 mg/dL), and higher in the $BA-CCl_4$ group (50.10 mg/dL) than the BA group (18.09 mg/dL). The lipid peroxide content was much higher in the $NC-CCl_4$ group (22.61 nmol/g) than the NC group (12.52 nmol/g), but the $BA-CCl_4$ (17.41 nmol/g) and BA (13.99 nmol/g) groups were similar. The glutathione content was much lower in the $NC-CCl_4$ group ($2.25\;{\mu}mol/g$) than the NC and BA groups, and decreased to $2.63\;{\mu}mol/g$ for the $BA-CCl_4$ group. The glutathione content of the $BA-CCl_4$ recovered to the level of that in the NC group.

Ascariasis symptoms penetrated into biliary tract are reported to be found much more in Korea than in foreign countries. And the present writer believes there are also many cases of biliary tract symptoms that are actually experienced but that are not reported. As a result of experiencing and nursing twenty cases of ascariasis symptoms of biliary tract, the present writer has got several conclusions, and reports them together with reference to sundry records. (1) The penetrating rate of ascariasis in male versus female was 1 to 1.5. Consequently the rate of female was higher than that of male. The highest age of the case was 67, the lowest 19, and the average age was 45.2. (2) As to symptoms, right upper quadrant abdomen pain and fat diet intolerance were the largest in number. By laboratory findings there were depressive pain on right upper quadrant abdomen in all the cases. (3) As to the location of ascariasis, choledochus occupied the largest part, and the longer illness history was, the more cases coexisting with calculus were found. (4) As to operative method, cholecystectomy and choledochotomy weres the largest in number, and choledochotomy T-tube was inserted in all cases. As to complication after operation, there were operative wound infection, excoriation through bile juice issue, etc. There were three cases of re-penetration of ascariasis and only one case of reoperation.

In this article, the concept of body fluid is explained in three aspects: the word meaning of body fluid, the origins of the definitions of the body fluid concept and the connotation and extension of body fluid. Investigating data about the time Hwangjenaegyeong(黃帝內經) was written, the author discovers that the meaning of "Aek(液)" is clear, but there are still questions about the meaning of "Jin(津)". The concept of body fluid derived from observation of life phenomenon and ancient philosophy on the "water". The concept of body fluid should be expressed as that body fluid is a general term for all normal liquids in the body. Within the meridians, as the composition of blood components; outside the meridians, constituting the intrinsic body fluids of various organs and tissues. This is the main part of body fluid, coming from diet, constituting the human body and maintaining human life activities, playing the roles of moistening and nourishing various of organs and tissues of the body. In addition, Interstitial fluid, all kinds of normal liquid secretion and metabolic products, such as sweat, tears, nasal discharge, saliva, slobber, gastric juice, intestinal fluid, urine, joint fluid, latex and so on, both belong to body fluid.

Grape is one of the most popular and widely cultivated fruits in the world. Although grape skin and seeds are waste product of the winery and grape juice industry, these wastes contain large amounts of phytochemicals such as flavonoids, phenolic acids, and anthocyanidins, which play an important role as chemopreventive and anticancer agents. We evaluated efficacies of grape skin and seeds on hepatic injury induced by dimethylnitrosamine (DMN) in rats. Treatment with DMN significantly increased levels of serum alanine transaminase, aspartate transaminase, alkaline phosphatase, and bilirubin. Diet supplementation with grape skin or seeds (10% daily for 4 weeks) prevented these elevations. The grape skin and seeds also restored serum albumin and total protein levels, and reduced the hepatic level of hydroxyproline and malondialdehyde. Furthermore, grape skin and seeds reduced DMN-induced collagen accumulation, as estimated by histological analysis of liver tissue stained with Sirius red. Grape skin and seeds also reduced hepatic stellate cell activation, as assessed by ${\alpha}$-smooth muscle actin staining. In conclusion, grape skin and seeds exhibited in vivo hepatoprotective and antifibrogenic effects against DMN-induced liver injury, suggesting that grape skin and seeds may be useful in preventing the development of hepatic fibrosis.
