  • Ginseng and probiotics have anti-obesity effects in mice fed a high-fat diet (HFD). Absorption of ginsenoside and colonization of probiotics occur in the intestine. In this study, a mixture of fermented ginseng and two probiotics, Bifidobacterium longum BORI and Lactobacillus paracasei CH88, was administered to HFD-fed mice for 9 weeks. The mixture significantly suppressed weight gain (p < 0.05, n = 8) and lipid deposition in the liver and adipose tissues as well as increased the mice's food intake. The adipocyte size of the adipose tissue was significantly decreased in the mixture-fed group, especially when 0.5% fermented ginseng and $5{\times}10^8/ml$ of the two probiotics were used (p < 0.05, n = 10). The expression of TNF-${\alpha}$ in adipose tissue was efficiently downregulated in the mixture-fed group (p < 0.05, n = 4). The supplement also improved the mice's fasting blood glucose levels (p < 0.05, n = 8) and total cholesterol feces excretion (p < 0.05, n = 8). The mixture of fermented ginseng and B. longum BORI and L. paracasei CH88 could have an anti-obesity effect and suppress lipid deposit in the liver and adipose tissues.

  • The effect of Chlorella vulgaris (CV) on the urinary excretion of di-ortho PCB congeners (PCB-138, -153) was investigated. Sprague-Dawley rats (6-weeks-old, n=10 rats/group) were randomly divided into one control (0CV) or 2% CV (2CV) or 5% CV (5CV) or 10% CV (10CV) groups, respectively. Composition of normal and chlorella meal-based diet were made up of 30% casein, 15% cornstarch, 50% sucrose, 5% cellulose, 5% coconut oil, 3.5% mineral mixture, 1 % vitamin mixture. All rats had free access to water and diet for 4 weeks. A significant increase in both PCB 138 and 153 in urinary level was detected in CV fed groups, 540% and 167% for 2CV, 155% and 89% for 5CV, 114% and 144% for 10CV group, respectively, when compared with their controls. These findings suggest that CV may have potential to eliminate body burden levels of dioxin-like PCB compounds.

  • Recent advances in genome sequencing technologies have enabled humans to generate and investigate the genomes of wild species. This includes the big cat family, such as tigers, lions, and leopards. Adding the first high quality leopard genome, we have performed an in-depth comparative analysis to identify the genomic signatures in the evolution of felid to become the top predators on land. Our study focused on how the carnivore genomes, as compared to the omnivore or herbivore genomes, shared evolutionary adaptations in genes associated with nutrient metabolism, muscle strength, agility, and other traits responsible for hunting and meat digestion. We found genetic evidence that genomes represent what animals eat through modifying genes. Highly conserved genetically relevant regions were discovered in genomes at the family level. Also, the Felidae family genomes exhibited low levels of genetic diversity associated with decreased population sizes, presumably because of their strict diet, suggesting their vulnerability and critical conservation status. Our findings can be used for human health enhancement, since we share the same genes as cats with some variation. This is an example how wildlife genomes can be a critical resource for human evolution, providing key genetic marker information for disease treatment.

  • There have been many studies indicating increased salt intake is related to elevated blood pressure (BP). Hypertension and pre-hypertension are prevalent in Korea. A national survey showed that the Korean average daily salt consumption was 12.5g, which is more than twice the current recommendation in the UK or USA. This study was performed to understand which aspects of the Korean diet contributed to high salt intake and elevated BP in Korea. The subjects consisted of 1,110 Korean adult men aged 30 to 49 years who were selected from the data of 2001 Korean National Health and Nutrition Survey, a nationwide cross sectional survey. The relationship of BP with sodium and high sodium food intakes were analyzed. After categorizing subjects according to their BP, the socio-demographic information and food and nutrients intakes were analyzed. BP increased with a larger amounts of sodium intake and the trend was significant with diastolic BP. However, the trends of BP for sodium densities of the diet were not. People with hypertension significantly tended to be older, larger, and less educated than people with normal BP. And they consumed more foods from the fats, oils & sweets group and larger amounts of discretionary sodium than normal people. The current report advocates that public health intervention, which improves the awareness of the role of salt on elevated blood pressure for the public, should be implemented in Korea.

  • To investigate the effects of the supplementation of carnitine and/or ${\gamma}$ -aminobutric acid (GABA), Sprague-Dawley male rats were orally treated with either an AIN-76 diet (control), a control diet plus ethanol (CE, 4 g ethanol/kg bw), CE plus L-carnitine (CEC, 0.5 g/kg bw), CE plus GABA (CEG, 0.5 g/kg bw), or CE plus L-carnitine plus GABA (CECG, 0.25 g/kg bw each) for 6 weeks. Serum triglyceride levels were increased in the CE group and were decreased significantly in the CEC, CEG and CECG groups. HDL-cholesterol was increased and LDL-cholesterol was decreased in the CEG and CECG groups compared with the CE group. Serum GOT and GPT levels increased by the chronic ethanol administration were decreased in the CEC group. In addition, we have evaluated the mRNA levels of carnitine palmitoyltransferase-I in those groups. Supplementation of carnitine/GABA had some recovery effects on the liver CPT-I mRNA levels which decreased by chronic ethanol administration. These results may suggest that supplementations of either L-carnitine or GABA aye effective on the recovery of chronic ethanol-related symptoms, but no combined effects were shown.

  • The effects of dried green tea leaf powders on serum lipid concentrations were evaluated in rats. Sixty male Sprague-Dawley rats weighing $100{\pm}10g$ were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Normal fat diet and normal and high fat diets with 1% dried green tealeaf powders. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by dried green tea leaf powders groups. The concentrations of serum triglyceride in rats fed the dried green tea leaf powders were lower than those in other groups. The concentrations of total cholesterol in green tea leaf powders the were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the dried leaf powders green tea were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the dried green tea leaf powders groups were tended to be lower than those of other groups. GPT and GOT were decreased in dried green tea leaf powders groups and than in the high fat group. LDHase was lower in the dried green tea leaf powders groups than in the high fat group. These results suggest that dried leaf powders green tea groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

  • This study was undertaken to examine the influence of soluble non-starch polysaccharides on growth performance, mucin secretion, and endogenous amino acid flows in weaner pigs. Different levels (0, 4 and 7.5%) of purified corn arabinoxylan (AX) or barley $\beta$-glucan extract (BG) were substituted for cellulose in a purified diet based on starch, sucrose and enzymatically hydrolyzed casein. All diets contained titanium oxide as an indigestible marker. Each experimental diet was fed to five, 6-wk old weaner pigs for 21 days. Average daily gain (p<0.05) and feed conversion ratio (p<0.01) were improved with dietary inclusion of 7.5% AX and BG, indicating high degradation rates of AX and BG in pigs. Crude mucin contents and endogenous nitrogen flow were increased (p<0.05) with increased levels of AX, but not with BG. Numerical increases in endogenous amino acid flow (EAAF) were observed with increased levels of AX but no definite trend with BG. Endogenous amino acid flow in pigs fed mixed NSP diets (4% BG and 3.5% cellulose) was significantly higher (p<0.05) than those fed 7.5% BG diets. Among diets containing pure sources of soluble non-starch polysaccharides, endogenous amino acid flows were highest in 7.5% AX (p<0.05), intermediate in BG, and lowest in control diet. Increased flows (p<0.01) of threonine, proline and serine in pigs fed 7.5% AX diets are consistent with the increased flow of crude mucin determined in this treatment. In conclusion, mucin and endogenous amino acid flows were increased with dietary inclusion of AX, which could be related to its physicochemical property, particularly its high water-holding capacity. In contrast, $\beta$-glucan, due to its high degradation rate in pig, may be considered as unimportant factor in inducing mucin and endogenous amino acid secretions, at least at levels such as those used in this study.

  • This study examined the relationship between the eating out behavior of families and a low-salt management by housewives in Jeonju area. Self-administered questionnaires were collected from 420 housewives. Descriptive statistical analyses was completed using SPSS v. 19.0 and Stata 13.0. The frequency of eating out and delivered food of housewives in their 20s was significantly higher than that of the older housewives (p<0.001). The high order frequency delivered foods were chicken menu and Chinese food. The determinants of the eating out menu were children's preference and meal time. The average scores of 'interest on low-salt diet', 'attitude toward a low-salt purchasing', and 'praxis a low-salt diet' were $2.70{\pm}0.95$, $3.06{\pm}1.13$, and $3.26{\pm}0.91$, respectively. The level of a low-salt management housewives in their 20s was higher than that of the older housewives (p<0.001). Regression analysis showed that various factors (e.g. age, number of children, education level, and frequency of the eating out) correlated with the low-salt diet of subjects. For the adequate eating out behavior of families and low-salt management of housewives, information and consumer education to take family-related situations into consideration are necessary.

  • This study was conducted to examine factors with attendance in hyperlipidemia nutrition eduction program among 101 hyperlipidemic outpatients (38 males 63 females) at Samsung Medical Center We employed the Health Belief Model (HBM) as the theoretical framework The individual nutrition education and counseling program was scheduled with 4- half hour session sin 2 to 4 weeks intervals. Upon initiation of the program a trained dietitian surveyed HBM constructs and psychosocial factors. The following were included perceived susceptibility to cardiovascular disease(CVD) perceived severity to CVD percieved benefits to diet modification perceived barriers to persistence in maintaining therapy and self efficicacy and social support from family Sociodemographic data health factors stress level nutrition knowledge, and 24-hour dietary recall behavior were also surveyed All these data was analyzed according to the number of nutrition sessions attended The subjects were 55.9$\pm$9.4 year old and 24.6$\pm$kg/㎡ Sociodemographic factors were not associated with the number of nutrition sessions attended HBM constructs and psychosocial factors were significantly associated with the number of nutrition sessions attended. According to Spearman correlation coefficients. From stepwis regression analyses using HBM constructs as independent variables perceive barriers to persistence in maintaining diet therapy (negative) proved to be the strongest predictors for the number of nutrition sessions attended (partial R$^2$= 72.3%) followed by perceived severity to CVD and self efficacy (model R$^2$=76.6% The findings indicate that HBM constructs and psychosocial factors were closely associated with patient attendance It suggests that information and guidance to minimize patients perceived barriers to diet therapy might help to improve patients to scheduled appointments in nutrition education programs.

  • The present research was conducted to investigate the effect of moderate exercise training on splenocyte inflammatory cytokines production in high fat diet-induced obese mice. To determine the effects of exercise training and low fat diet on splenocyte, C57BL/6 male mice (4 weeks aged, n=20) were fed a high fat diet (45% fat diet) for 5 weeks so that obesity was achieved intentionally. These obese mice were then divided into 2 groups; HLC (low fat diet and control n=10), and HLE (low fat diet and exercise n=10). HLE mice performed 8 weeks of exercise training on a motorized treadmill by running for 30-60 min/day at 10-22 m/min, 0% grade, five times per week. After exercise training, all the splenocyte was collected and Con A (concanvalin A, 10${\mu}g/ml$) was used to stimulate the cells, after which IL-1${\beta}$, IL-6, TNF-${\alpha}$ were measured by bio plex. Independent t-test was used and p value under 0.05 was considered a statistical significance. Splenocyte IL-1${\beta}$, IL-6, TNF-${\alpha}$ production of HLE stimulated by Con A was significantly lower than that of HLC (p<0.01). These findings suggest that moderate exercise has beneficial effects on splenocyte inflammatory cytokines in high fat diet induced obese mice.
