This is a non-experimental and retrospective study aimed at determining the effects of long-term hospitalization on the body mass index (BMI) and lipid metabolism in long-term hospitalized patients. The study subjects included 120 patients aged 40-65 years who were hospitalized for >3 months in 2 long-term care hospitals in Gyeonggi-do, South Korea. In this study, the BMI and levels of total cholesterol, triglycerides (TG), high-density lipoprotein (HDL), and low density lipoprotein (LDL) at admission and 3 months after hospitalization were compared and analyzed, and the related changes over time were followed up. The general characteristics of the subjects were analyzed by using descriptive statistics and frequency analysis. In addition, logistic regression analysis was performed to determine the effects of the general characteristics on the BMI and Dyslipidemia. The changes in the BMI and blood lipid levels between admission and 3 months after hospitalization were analyzed using the paired t-test. The results showed that with regard to the changes in the blood lipid levels, the triglyceride levels significantly increased 3 months after hospitalization (p<.05). These findings imply that long-term hospitalization for care and rehabilitation after acute-phase treatment should be considered a potential high-risk factor for dyslipidemia, which could be prevented or alleviated by providing the patients with health education, including exercise and dietary education.

This study targeted 4,572 middle-aged women to examine the relationship between nutritional status and dietary inflammatory index according to blood glucose level using data from the Korean National Health and Nutrition Examination Survey (KNHANES). Data were analyzed using complex survey chi-square, General Linear Model and logisitc regression in SPSS Win 25.0 program. Women with high blood glucose (normal blood sugar→diabetes) had high rates of obesity and blood TG/HDL-cholesterol ratio. On the other hand, the Mean Adequacy Ratio (10 nutrients) and the intake of anti-inflammatory foods: beans, seeds, mushrooms, and fruits, were lower in the diabetic category. When we analysed the association between blood glucose and the Dietary Inflammatory Index, the risk of pre-diabetes and diabetes was significantly higher in the most pro-inflammatory diet category (Q5) compared to the most anti-inflammatory diet category (Q1). These findings suggest that nutritional education emphasizing the intake of various foods should be effectively conducted effectively in order to improve blood glucose among middle-aged women.

Objectives : The purpose of this study is to determine whether Rhus verniciflua Stokes with Latin name Lacca Sinica Exsiccata, and Eucommia ulmoides Oliver with Latin name Eucommiae Cortex Extract Combination (ILF-RE) improves laboratory test results in participants with liver function disorder. Methods : This study was conducted at Woosuk university Korean medicine hospital where participants with high serum alanine transaminase (ALT) levels from 45 to 135 U/L were enrolled. Subjects received ILF-RE 3.6 g (1.2 g/day as ILF-RE) or placebo 3.6 g for 12 weeks. It was confirmed that urushiol was not detected in ILF-RE. The primary outcomes were the decrement degree of serum ALT and gamma-glutamyl transferase (GGT) levels between two groups. The secondary outcomes were the decrement degree of serum aspartate transaminase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LD), total bilirubin, total cholesterol, triglyceride (TG) and fatty liver index (FLI) levels between two groups. Adverse events, skin prick tests, laboratory tests, and vital signs were observed and analyzed to confirm the safety of ILF-RE.1) Results : In the ILF-RE group, the liver function index ALT, GGT, lipid metabolism index TG, and fatty liver index FLI were significantly decreased compared to the placebo group. There was no significant difference in ILF-RE group in terms of adverse events, severe adverse events, skin prick test, laboratory test, and vital signs compared with placebo group. Conclusions : ILF-RE was found to be effective in improving liver function. In addition, no clinically significant adverse events or body changes were observed during this study.

To meet the ever increasing quality demand of coated papers and duplex boards, the local gloss variation and print unevenness must be avoid. To do this, surface roughening phenomenon which affects local gloss and print unevenness was investigated. In this study, the effect of roughness and densification of sheet obtained at various calendering conditions on surface roughening was examined. To evaluate the calendering effect properly we introduced a new value of roughening index by moisture for evaluation of surface roughening. Caliper and roughness of sheet decreased with increasing of calendering temperature and pressure, and the remarkable reduction of those properties occurred at the temperature around Tg. Roughening index increased when the amount of water increased and calendaring temperature and pressure increased. And as the sheet became denser by calendering, the roughening index increased to some extent. But roughening index by moisture is the lowest for sheet precalendered at higher temperature condition. When the surface of calendered sheet is rougher, there is more roughening of surface. The severe condition of calendering made the roughening index by moisture small.

The purpose of this study was to obtain basic data for nutrition education of the children in a health promoting elementry school. The data was collected by a questionaire of food habits, and anthropometric measurement and biochemical test in comparison with obesity index. The study subjects were boys and girls aged 10 to 12 years who participated in the “99 Children Nutrition Camp”. The average obesity index was 1.7$\pm$21.6% in boys and -11.4$\pm$12.6% in girls. After school, major leisure items were significnatly different by gender but both boys and girls played mainly computer game. In concern for body image and eating habits, girls had more concern and girls had attempted weight control more than boys. 80.2% of subjects had prejudice for special food, especially, all subjects in the severely underweight group had prejudice. But this tendency was significantly decreased with the increasing obesity index. The lowest preferency was for vegetables(64.4%). The tendency of prejudice of subjects was higher whose mother are thirties than those of subjects whose mother are in fourties. The serum GOT and GPT values were significantly higher in overweight and obese group than the other groups. The only serum T-chol was significantly higher in boys than in girls. The number of risk factors related to coronary heart disease(CHD) based on coresponding criteria of TG, T-chol, HDL-chol, and LDL-chol was not increased significantly with the degree of obesity index. The results indicated the need of nutritional management for the children. At a point of view, to educate children early who are able to change food habits and life-styles means to help heathy growth and to deliver up heathy adults. Active nutrition education for both children and mothers will be recommended with joint participation of nutritionists in community public health center and elementary school.

This study was designed to investigate the biochemical pollutant marker for diagnosis of marine pollutions by the changes in lipid components of the flounder (Pleuronichthys cornutus) in the Yellow Sea of Korea. Hemoglobin levels in serum of wild flounders in the yellow Sea were significantly lower $(15\~30\%)$ than those of wild flounder in Pohang (control) of the East Sea. Triglyceride (TG) contents in serum of wild flounders in the Yellow Sea were higher $(15\~50\%)$ than those of wild flounder in Pohang. Total and low density lipoprotein (LDL)-cholesterol contents in serum of flounders in the Yellow Sea were significantly higher $(20\~25\%\;and\;15\~35\%,\;respectively)$ than those of wild flounder in Pohang. Atherogenic index (Al) in serum of wild flounders in the Yellow Sea were significantly higher $(10\~60\%)$ than these of wild flounder in Pohang but T-Chol/PL ratios showed almost no change in serum of flounders in the Yellow Sea we examined. These results suggest that near-coastal water as well as neritic water of the Yellow Sea might be affected by pollutant input.

This study was to evaluate the protective effect of vitamin E against long and short-term stress in ICR mice. Two groups which had been bred for 5 months (equivalent to human beings aged 20) were treated by immobilization stress for 8 weeks with or without vitamin E, and one out of two groups was continuously bred until they become 18 months old (equivalent to human senescence) with or without Vitamin E. Afterwards, the changes of serum and hepatic metabolites were investigated on the basis of the index of stress-related in vivo oxidative damage. As a result, it was found that stress increases serum triacylglycerol and aspartate aminotransferase (AST) in the long and short-term, and decreases serum HDL-cholesterol. In addition, stress concerned the decrease of total antioxidant status (TAS) and superoxide dismutase (SOD) as well as the increase of malondialdehyde (MDA) in liver. These results suggest that stress in one’s youth causes negative results in TG, HDL-cholesterol, AST, TAS, SOD and MDA measured in one’s senescent. The administration of vitamin E in the stressed mice decreases serum TG and AST that are increased by stress, and exerts influence on the increase of serum HDL-cholesterol. Also vitamin E recovered the values of liver TAS, SOD and MDA in the stressed mice. In conclusion, vitamin E represented protective effect in the stressed mice to some degree.

The present study evaluated the effects of isoflavone-rich bean sprout on the lipid metabolism in ethanol-treated rats. Fifty male Sprague-Dawley rats were randomly divided into five groups: normal control, alcohol control, low soybean sprout+ethanol (low SS), high soybean sprout+ethanol (high SS) and isoflavone extract+ethanol (IE). They were fed experimental diets based on Lieber-DeCarli liquid diet for 40 days. Body weight, food intake and feed efficiency ratio (FER) of ethanol-treated groups were significantly suppressed compared with that of the normal control group. Among the ethanol-treated groups, high SS group showed in significant increase in the body weight, food intake and FER. Supplementation of isoflavone-rich soybean sprout powder or isoflavone extract significantly decreased plasma triglyceride (TG), total cholesterol (TC), atherogenic index (AI) and increased the ratio of HDL-cholesterol to TC. Supplements also significantly decreased total lipid, TG and TC in liver tissue compared with that of alcohol control. There was a significant decrease in hepatic lipid peroxidation products in IE group compared with other ethanol-treated groups. This results suggest that supplementation of isoflavone-rich bean sprout powder may exert beneficial effects on lipid metabolism in chronically alcohol-treated animals by improving lipid profiles in plasma and liver tissues.

The purpose of this study was to investigate the correlations among the anthropometry, serum lipid levels and nutrient intake in Korean female university students. The subjects were 119 female students at a university located in Incheon. This study was conducted using a self-administered questionnaire. Anthropometric data were measured and blood lipid levels were analyzed. Nutrient intake collected from 3 day-recalls was analyzed by the Computer Aided Nutritional Analysis Program. The data were analyzed by SPSS 10.0 program. Average age, height and weight of the subjects were 20.9 years, 160.1cm and 54.3kg, respectively. Average serum TG (triglyceride), total cholesterol, HDL-C (high density lipoprotein-cholesterol) and LDL-C (low density lipoprotein-cholesterol) levels of the subjects were 69.47mg/dl, 146.85 mg/dl, 50.49mg/dl and 82.52mg/dl, respectively. Average AI (atherogenic index) of the subjects was 2.03, which was in the normal range based on risk values. Average intake of most nutrients except protein, vitamin B$_1$, vitamin C and phosphorus were lower than the Korean RDA. Especially calcium and iron intakes of the subjects were under 65% of the Korean RDA. Serum TG, total cholesterol and LDL-C levels were negatively correlated with DBP (diastolic blood pressure). HDL-C/LDL-C and HDL-C/total cholesterol were positively correlated with height. Age was positively correlated with phosphorus intake. DBP of the subjects was positively correlated with calcium and iron intakes. Serum TG level was positively correlated with total cholesterol, HDL-C, LDL-C and AI, while negatively correlated with HDL-C/total cholesterol. Total cholesterol level was positively correlated with HDL-C, LDL-C and AI, while negatively correlated with HDL-C/LDL-C, HDL-C/total cholesterol. HDL-C level was positively correlated with LDL-C, HDL-C/LDL-C and HDL-C/total cholesterol, while negatively correlated with AI. LDL-C level was negatively correlated with HDL-C/LDL-C and HDL-C/total cholesterol, while positively correlated with AI HDL-C/LDL-C ratio was positively correlated with HDL-C/total cholesterol and AI. HDL-C/total cholesterol was negatively correlated with AI. Fat intake was positively correlated with total cholesterol, HDL-C level, and vitamin B$_2$ intake was positively correlated with TG, HDL-C/LDL-C. Therefore, nutrition education is necessary for female university students to promote the lipid profile and to optimize the nutritional status. (J Community Nutrition 4(3) : 151∼158, 2002)

Purpose The importance of quality control by the error to a minimum, which for the purpose of enhancing the reliability of the examination is not be emphasized excess. Currently, most nuclear medicine laboratory are conducting the internal and external quality control, and they are applying the Levey-Jennings or Westgard Multi-Rules by using the commercialized quality control materials. The reliability of the nuclear medicine blood test which affects the diagnosis of patients and the treatment policy is being secured through this quality control activity. Therefore, researchers will evaluate the utility of the statistic quality control using the population distribution of the nuclear medicine blood test conducted targeting the checkup examinees by the additional technique of the reliability improvement. Materials and Methods A statistic analysis was performed about 12 items of the nuclear medicine blood test targeting 41,341 peoples who used the health screening and promotion center in Asan Medical Center from January, 2014 to December, 2014. The results of 12 items of the nuclear medicine blood test was divided into the monthly percentage of three groups: within reference values, over reference, and under reference to analyze the average value of the population distribution, standard deviation, and standard deviation index (SDI). Results The standard deviation of the population distribution mostly showed a result within ${\pm}2SD$ in all groups. However, When the standard deviation of the population distribution represented a result over ${\pm}2SD$, it was confirmed SDI was showing a result of SDI > -2 or SDI > 2. As a result of analyzing the population distribution of 12 items(AFP, CEA, CA19-9, CA125, PSA, TSH, FT4, Anti-Tg-Ab, Anti-TPO-Ab, Calcitonin, 25-OH-VitD3, Insulin) of the nuclear medicine blood part basic test, when SDI of the monthly percentage which deviated from the reference values was over ${\pm}2.0$, CA19-9 September was 2.2, Anti-Tg-Ab may was 2.2, Insulin January was 2.3, Insulin March was 2.4. It was confirmed these cases were attributed to the abnormality of the test reagent (maximum combination rate of isotope reagent declined) and the decline of the test response time. Conclusion The population distribution includes the entire attribute which becomes the study object. It is expected the statistic quality management using the population distribution which was conducted targeting the checkup examinees by dividing into three groups: within reference values, over reference, and under reference by means of this characteristics will be able to play a role of complementing the internal quality control program which is being carried out in the laboratory.
