The purpose of this study is to examine the relationships among body composition, dietary intake, exercise, and life style in children(M=80, f=102) of the 5th and 6th grades of elementary school. Anthropometry and multifrequency bioelectrical impedance analysis were conducted to estimate body composition. Dietary intake, exercise, and life style were determined by using questionnaires. When obesity was classified greater than 120% of the ideal body weight, the prevalence rates of obesity were 31.2% for boy and 20.6% for girl. There were significant differences in body composition between nonobese(NO) and obese(OB) groups. Mean fat mass(FM) and lean body mass(LBM) were 8.6kg and 27.7kg for NO group and 16.7kg and 32.3kg for OB group, respectively. Also a significant difference was found in hydration rate(TBW/body weight)between groups( <0.01). No significant difference was found I total calorie intake and nutrient intakes between groups. No difference was found in the frequency and duration of outdoor exercise and indoor activities. Mean sleeping hours was 8-9hours for 62% of nonobese children and for 59% of obese children. However, calorie intake per body weight was significantly lower inobese children than in nonobese. The present study showed that significant differences existed in their body size and composition between NO and OB groups , while no differences existed in daily calorie intake, excercise , and life style. This may indicate that important obesity-promoting factors of early onset obesity may rely on other factors such as hereditary or environmental factors besides factors considered. Further studies are required to understand obesity-promoting factors in children. (Korean J Community Nutrition 2(5) : 680∼686, 1997)

This study was carried out to determine, the effects of sodium alginate and cellulose on the plasma lipoportein composition and cholesterol metabolism inrats.Each experimental diet contained 105 sodium alginate and cellulose by weight, respectivley and rats were fed fro 4 weeks. The results obtained were as follows : The feeding of sodium alginate and cellulose decreased total plasma cholesterol slightly . total cholesterol of Chylomicron /VLDL- , LDL-fraction and liver were decreased significantly insodium alginate group. HDL-cholesterol was slightly increased in soidum alginate group. The feeding of sodium alginate significantly lowered plasma , Chylomicron VLDL-, LDL-fraction and liver TG concentrations compared with those fed fiber-free diet . The HMG-CoA reductase activity was not different among diet groups but the lowest activity was observed in sodium alginate group. The feeding of sodium alginate significantly increased fecal cholesterol , TG, and bile acid excretion . In summary , the ingestion of sodium alginate decreased cholesterol and TG concentrations of plasma and liver. This may be explained by the facts that fecal cholesterol, bile acid and TG level were increased significantly in sodium alginate group.

This study was performed to investigate the effect on polyunsaturate fatty acid diets and feeding periods on the antithrombosis. the hematological changes in the blood and fatty acid compositions of platelets in rats. Each group of rats was fed a diet containing 20%(W/W) corn oil beef tallow sardine oil and the general stock diet for 10, 20. 40 and 80 days. Rats fed sardine oil diet showed significantly longer bleeding time than any other diet groups after 20 days feeding The whole blood clotting time of sardine oil group fed for 80 days was increased significantly. The number of platelet and the concentration of hemoglobin showed no significant difference among all groups. The number of white blood cell was decreased continously in sardine oil group after 10 days feeding. The level of malondialdehyde generation during thrombin-induced aggregation of platelets was decreased continously in sardine oil grou after 20 days feeding. With regard to the composition of platelet fatty acid the ratio of eicosapentaenoic acid(EPA 20: 5 $\omega$-3) to arachidonic acid(AA 20:4 $\omega$-6) was increased in sardine oil group but decreased in corn oil groups and beef tallow groups with days. In conclusion the rats fed sardine oil diet for more than 20 days showed the fact that EPA induced the antithrombosis. the changes in number of white blood cell and the fatty acid composition of platelets.

This study investigates the relationship between cancer cachexia and the gut microbiota, focusing on the influence of cancer on microbial composition. Lewis lung cancer cell allografts were used to induce cachexia in mice, and body and muscle weight changes were monitored. Fecal samples were collected for targeted metabolomic analysis for short chain fatty acids and microbiome analysis. The cachexia group exhibited lower alpha diversity and distinct beta diversity in gut microbiota, compared to the control group. Differential abundance analysis revealed higher Bifidobacterium and Romboutsia, but lower Streptococcus abundance in the cachexia group. Additionally, lower proportions of acetate and butyrate were observed in the cachexia group. The study observed that the impact of cancer cachexia on gut microbiota and their generated metabolites was significant, indicating a host-to-gut microbiota axis.

Purpose: This study aims to determine what changes occur in body composition and performance by subjecting youth soccer players to weight training and combined training, which are known to be effective in improving anaerobic capacity, for 6 weeks. Research design, data, and methodology: This study was conducted on 30 high school soccer players from S City who had no current injuries or medical problems and had been registered as players with the Korea Football Association for more than 3 years. Subjects were divided into a weight training group (WTG, n=15) and a combined training group (CTG, n=15). Training lasted 6 weeks, and measurements were taken before and after training. Mean (M) and standard deviation (SD) were calculated to present the descriptive statistics of all dependent variables. Paired t-tests were used to test for within-group differences. Further, Independent t-tests were employed to test for between-group differences. Results: In terms of body composition, height significantly increased in WTG and CTG, and body fat percentage significantly decreased in CTG. As for performance, WTG's 20m sprint record decreased significantly. Conclusion: As a result, this study confirmed that weight training improved the 20m sprint ability of youth soccer players. Future research could provide more useful information by extending the study period and incorporating the physical characteristics of adolescents.

It remains to be determined whether there is a geographical distribution pattern and phylogenetic signals for the Mycena strains with seed germination of the orchid plant Gastrodia elata. This study analyzed the community composition and phylogenetics of 72 Mycena strains associated with G. elata varieties (G. elata. f. glauca and G. elata. f. viridis) using multiple gene fragments (ITS+nLSU+SSU). We found that (1) these diverse Mycena phylogenetically belong to the Basidiospore amyloid group. (2) There is a phylogenetic signal of Mycena for germination of G. elata. Those strains phylogenetically close to M. abramsii, M. polygramma, and an unclassified Mycena had significantly higher germination rates than those to M. citrinomarginata. (3) The Mycena distribution depends on geographic site and G. elata variety. Both unclassified Mycena group 1 and the M. abramsii group were dominant for the two varieties of G. elata; in contrast, the M. citrinomarginata group was dominant in G. elata f. glauca but absent in G. elata f. viridis. Our results indicate that the community composition of numerous Mycena resources in the Zhaotong area varies by geographical location and G. elata variety. Importantly, our results also indicate that Mycena's phylogenetic status is correlated with its germination rate.
