Interactive effects among eating behavior, obesity and serum lipid levels were studied in 117, 4~12 year old children residing suburban Seoul. Fasting blood samples are obtained and analyzed for serum triglycerides (TG), total cholesterol(TC), high density lipoprotein-cholesterol(HDL-C) and hematochrit. Obesity was determined by weight for length index(WLI)and the information on eating behavior including food habits and dietary intakes was obtained by questionaire using food record method for 2-consecutive days. Over 40% of children was classified overweight or obese by WIL and children's physical parameters were closely related to those of parents implying genetic influence on obesity. Although it did not reach the statistical significance, there was a tendency of higher TG, TC and low density lipoprotein-cholesterol(LDL-C)levels among girls compared to boys. Blood lipid levels of obese children were similar to those of other groups except TG, which was significantly higher(p<0.05) in obese group. Nutrient intakes seemed adequate in all subjects except iron, calcium and total calorie which were lower than RDAs. Lacking significant relationship between individual nutrient intake and obesity, there was significant correlation between food intake and blood lipid level especially in 10-12 year old group. Vegetable intake was negatively related to TG, LPH(LDL-C/HDL-C) and atherogenic index(AI), and positively to HDL-C. Skipping breakfast and frequent eating out appeared to cause imbalances in nutrient intake. These findings clearly revealed the influence of eating behavior on childhood obesity along with blood lipid profile. To ensure the proper growth and health of these children, devising method and developing media for nutrition education suited to our society should be accomplished first. With well-planned nutrition surveys and thorough intention, childhool obesity could be prevented from progress into adulthood obesity.

BACKGROUND/OBJECTIVES: Rheumatoid arthritis (RA) is associated with an excess mortality from cardiovascular disease which is likely attributed to an atherogenic lipid profile. Among nutritional factors vitamin K has been recently focused as a pivotal nutrient in improvement of lipid related markers. Thus, this study was designed to determine the effects of vitamin K on lipid profile in this disease. SUBJECTS/METHODS: Fifty eight patients with definitive RA were participated in the present double blind placebo controlled study. They were randomly allocated into two groups to receive vitamin $K_1$ as phylloquinone [10 mg/day] (n = 30) or placebo pills (n = 28), for eight weeks. In order to control the effects of probable confounders dietary intakes, anthropometric measurements including weight and height, clinical status using disease activity score-28 (DAS-28), physical activity and anxiety status were evaluated at baseline. Moreover, serum levels of lipid related markers including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) were measured at baseline and at the end of intervention. RESULTS: There were no significant differences between the two groups regarding any of the baseline characteristics. After adjusting for some relevant confounders, in comparison between two groups, we observed no significant changes in lipid related markers at the end of intervention. Also, there was no significant difference between before and after intervention values within groups (P > 0.05). CONCLUSIONS: Function of vitamin $K_1$ in lipid profile modification remains still controversial. This study showed that vitamin $K_1$ has no effect on lipid profile in women with rheumatoid arthritis. Further studies with a longer follow-up are required to determine the effects of vitamin K on atherogenic lipid profile.

Objectives : This study was designed to protect effect on atherosclerosis through regulation of low density lipoprotein(LDL) by 70 % ethanol extract Ganoderma lucidum (GL) in LDL receptor knockout mouse (LDLr ko mice) fed Western diet.Methods : The LDLr ko mice were divided into 3 groups ; Control, GL100, and GL300. After grouping, LDLr ko mice were fed Western diet. The GL (100 or 300 mg/kg body weight/day, p.o.) was administered every day for 8 weeks. The body weight and food intake were measured every day. The changes in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, triglyceride (TG), total cholesterol (TC), and high-density lipoprotein (HDL) in serum were analyzed after experiment.Results : The LDLr ko mice fed Western diet were increased body weight gain and blood biochemistry parameters such as ALT, AST, TG, TC, and LDL. However GL300 group significantly reduced the body weight. Also TG, TC, and LDL level did not increase. The levels of ALT, AST, HDL were not changed. Also, LDLr ko mice model liver were observed lipid drop, but GL groups did not appear. Futhermore, histological analysis of GL groups aorta tissue were similar to NOR groups.Conclusions : We confirmed that whether GL administration is protect atherosclerosis or not. As the results, blood biochemistry and histological analysis did not changed much in GL administration groups. This study provides scientific evidence that GL protect the atherosclerosis through the reduction of LDL cholesterol. Therefore GL has potential medicine inhibition of atherosclerosis.

Hyperlipidemia is a major predisposing factor of atherosclerosis and cerebrovascular accidents. In effort to develope a hypolipidemic drug from medicinal herb, We tested three prescriptions of traditional medicine for the lipid lowering effect on diet-induced hyperlipidemic rats. GyejI-Bokryung-Hwan, Ohyak-Sunki-San, and Shihoga-Yongol-Moryu-Tang were selected based on the comnon prescriptions for patients with hyperlipidemia-related diseases. Water extract from each prescriptions was made by the method used in the clinical setting, and administered intragastrically once a day, for 4 weeks. Fenofibrate and lovastatin were given by the same method as the control drugs. Blood levels of total cholesterol(TC), high density lipoprotein(HDL), low density lipoprotein (LDL), and triglyceride(TG) were measured before, 1, 2, 3, and 4 weeks after starting the drug administration. All of the traditional prescriptions did not show lipid lowering effect, while fenofibrate lower the blood cholesterol levels(TC;from 215mg/dl before to 182m41 at 4 weeks-point of drug administration, and LDL ;from 203mg/dl before to aut 161, and 163mg/dl at 3 and 4 week-point respectively). Oyak-Sunki-San increased the level of TC (from 283mg/dl to over 350mg/dl starting from the first week of drug administratin). Effects on TG variable in the cases of traditional medicines and control drug In conclusion, any of the three traditional medical prescriptions did not decrease the level of blood cholesterol.

Objectives: The purpose of this study was to investigate the effectiveness and safety of ginseng seed oil in healthy subjects who have mild liver dysfunction. Methods: A randomized, double blinded, placebo-controlled trial was conducted. A total of 167 subjects visited Semyung University Hospital from July 1st, 2016 to June 10th 2017. Except for the 103 excluded subjects, 64 subjects were randomized into one of the two groups: an treatment group(n=33) and control group(n=31). Subjects were randomly given either ginseng oil seed capsules or indistinguishable placebo capsules(2 capsules per dose, twice per day). Laboratory tests(aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol) were performed to evaluate the effectiveness after 6, 12 weeks of treatment. Vital sign, laboratory test were performed to assess safety at every visit. Results: There were no significant differences in efficacy between treatment group and control group. There were some adverse events with no significant difference in symptoms and frequency between treatment group and control group. Conclusions: Although the efficacy of ginseng seed oil was not proved, ginseng seed oil did not worsen liver function and proved its safety. More study of ginseng seed oil and clinical trials are necessary to increase the usefulness of above-ground parts of ginseng.

Fresh unripe whole fruits of Luffa tuberosa (Roxb.) or Momordica tuberosa (Roxb.) Cogn. (Cucurbitaceae) were evaluated for the antidiabetic and hyperlipidemic potential in streptozotocin (STZ) induced diabetic rats. Diabetes was induced by administration of intra-peritoneal injection of streptozotocin at a dose of 55 mg/kg body weight. After the induction of diabetes aqueous extract of L.tuberosa (AELT) was administered orally at doses of 250 and 500 mg/kg. body weight/day for a period of 14 days. The Fasting blood glucose (FBG) levels, serum insulin levels, changes in body weight, food and liquid intake were measured. In diabetic rats, the AELT exhibited significant reduction in blood glucose levels. Biochemical assay of plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), glycogen content and glucose-6-phosphatase activity in liver were assessed. Antihyperlipidemia in diabetic rats after the extract supplementation was confirmed by significant reduction in the levels of above mentioned hyperlipidemic indicators. This study focus on the efficacy of L.tuberosa fruits for the management of experimental STZ induced diabetic rats and provides the scientific basis of ancient herbal therapy and use of these fruits as vegetable.

BACKGROUND/OBJECTIVE: The goal of the present study was to investigate the effects of moderate caloric restriction on ${\beta}$-cell function and insulin sensitivity in middle-aged obese Korean women. SUBJECTS/METHODS: Fifty-seven obese pre-menopausal Korean women participated in a 12-week calorie restriction program. Data on total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), and fasting serum levels of glucose, insulin, C-peptide, blood pressure, leptin and anthropometrics were collected. A dietary intake assessment was based on three days of food recording. Additionally, ${\beta}$-cell function [homeostasis model assessment of ${\beta}$-cell (HOMA-${\beta}$), insulinogenic index (ISI), C-peptide:glucose ratio, and area under curve insulin/glucose ($AUC_{ins/glu}$)] and insulin sensitivity [homeostasis model assessment for insulin resistance (HOMA-IR), Quantitative insulin-sensitivity check index (QUICKI) and Matsuda index (MI)] were recorded. RESULTS: When calories were reduced by an average of 422 kcal/day for 12 weeks, BMI (-2.7%), body fat mass (-10.2%), and waist circumference (-5%) all decreased significantly (P < 0.05). After calorie restriction, weight, body fat percentage, hip circumference, BP, TC, HDL-C, LDL-C, plasma glucose at fasting, insulin at fasting and 120 min, $AUC_{glu}$ and the insulin area under the curve all decreased significantly (all P < 0.05), while insulin sensitivity (HOMA-IR, QUICKI and Matsuda index) measured by OGTT improved significantly (P < 0.01). CONCLUSIONS: Moderate weight loss due to caloric restriction with reduction in insulin resistance improves glucose tolerance and insulin sensitivity in middle-aged obese women and thereby may help prevent the development of type 2 diabetes mellitus.

This study aimed to assess the effects of neutral detergent fiber (NDF) from rice straw on blood metabolites and productivity of dairy cows in the tropics. Eight Holstein ${\times}$ indigenous (75-87.5% Holstein) were randomly allocated to dietary treatments according to a double $4{\times}4$ Latin square design. Contents of roughage NDF from rice straw were 12.8, 14.8, 16.8 and 18.8% dry matter (DM) and concentrate NDF content was 10.2% DM, so that levels of dietary NDF were 23, 25, 27 and 29% DM. Dietary treatments were isonitrogenous and isocaloric diets. The average maximum and minimum temperature humidity index during the experimental period were 85.6 and 76.9, respectively. Plasma glucose (p<0.05), dry matter intake and 4% fat corrected milk (p<0.01) decreased with increasing contents of roughage NDF from rice straw, while rectal temperature, serum urea, cortisol, low density lipoprotein-cholesterol (p<0.05), serum total protein and ${\beta}$-hydroxybutyrate (p<0.01) increased. Serum triglyceride, total cholesterol and high density lipoprotein-cholesterol were not affected (p>0.05). Decreased rectal temperature and concentrations of serum cortisol were associated with decreasing levels of ${\beta}$-hydroxybutyrate and serum urea, but with increased concentrations of plasma glucose, DMI and 4% fat corrected milk indicating that lactating cows fed lower fiber diets were in lower oxidative stress. Therefore higher intake and metabolic efficiency in dairy cows fed diets lower in roughage NDF from rice straw would be of an advantage in productive systems under tropical conditions.

The present study was carried out to evaluate the physiological effects of mushroom supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or mushroom supplementation group. Mushroom supplementation was provided 3 times a day for 4 weeks. We found that total dietary fiber intake was about 2.5 times higher (30.3 g vs. 12.3 g) in subjects receiving mushroom supplementation than in the control group. Two groups maintained the same food intake and amount of activity, exercise during the supplementation. We observed no difference in age, height, weight, BMI (body mass index), blood pressure between the groups. Nutrient intake did not differ appreciably between the two groups, except for fiber intake, during the supplementation. Fasting blood glucose levels and 2-hour postprandial blood glucose levels were significantly lower in those ingesting mushroom than in controls. Furthermore, the concentrations of low-density lipoprotein cholesterol were decreased significantly in the mushroom supplementation group. Small changes were observed in the concentration of total cholesterol, triglyceride, high-density lipoprotein cholesterol of those supplemented with mushroom, but these changes were not statistically significant. Activities of superoxide dismutase and catalase with mushroom supplementation were higher than in controls, but and glutathione peroxidase activity was not affected. The levels of thiobarbituric acid reactive substance of mushroom group were lower than control group, but were not significant. We conclude that addition of mushroom influences glycemic control and may be effective in lowering blood lipids and improving antioxidant enzyme activities. Accordingly, such effects may reduce risk factors for cardiovascular disease in patients with type 2 diabetes. However, to confirm these effects and to make dietary recommendations for patients with type 2 diabetes, further studies are necessary.

Preserved egg, a kind of alkaline-fermented food, is a traditional egg product in China. Here, we investigated the nutritional functions of preserved eggs by in vivo and in vitro experiments. The results of in vivo studies showed that the levels of triglycerides (TG), total cholesterol (TCHO) and low-density lipoprotein cholesterol/high density lipoprotein cholesterol (LDL-C/HDL-C) were significantly decreased (p<0.05) in the liver of rats treated with preserved eggs. Meanwhile, the levels of two important cancer markers, interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), were also significantly decreased (p<0.05) in treated rats. In vitro studies were performed on Caco-2 cells, a human epithelial colorectal adenocarcinoma cell line. It demonstrated that the gastrointestinal (GI) digests of preserved eggs significantly accelerated (p<0.05) the apoptosis by upregulating caspase-3 in the Caco-2 cells. Besides, after treated with preserved eggs, the half maximal inhibitory concentration (IC50) of preserved eggs digests to Caco-2 cells was 5.75 mg/mL, indicating the significant inhibition of cell proliferation provided by preserved eggs (p<0.05). The results shown in this study demonstrated that preserved eggs may be a novel functional food involved with antilipemic, anti-inflammatory activity as well as the effect on accelarating the apoptosis of Caco-2 cells.
