Objectives : The purpose of this study was to investigate how Rhei Radix et Rhizoma affects on insulin resistance and adipose tissue inflammatory response in high fat diet induced obese C57BL/6 mice. Methods : Obesity was induced in C57BL/6 mice by high fat diet for 12 weeks. Models were divided into 3 groups (n=6) of normal diet, high fat diet (HFD), and high fat diet with Rhei Radix et Rhizoma and investigated for 12 weeks. We measured body weight, FBS and oral glucose tolerance test (OGTT), serum insulin, homeostatic model assessment-insulin resistance (HOMA-IR), weight of liver and epididymal fat pad. Inflammatory markers such as adipose tissue macrophage (ATM), tumor necrosis factor-${\alpha}$ and interlukin-10 and CD68 of epididymal adipocyte were determined to evaluate the effect of Rhei Radix et Rhizoma on adipose tissue inflammation. Results : Compared with the HFD group, we observed loss of body weight and epididymal fat pad weight, improvement of glucose level and HOMA-IR, reduction of ATM and gene expression of TNF-${\alpha}$, CD68 in the high fat diet with Rhei Radix et Rhizoma group. Conclusions : This study suggests that Rhei Radix et Rhizoma has effects on insulin resistance and adipose tissue inflammatory response in high fat diet induced obese mice.

This study was carried out to investigate the dietary effects of chitosan mixture (CM), an herbal medicine mixture with Sukjihwang (HS), and CM containing HS (CHS) on obesity in an induced obese model of rats fed high-fat only (HF), in which supplemented diets of 5% CM (HCM), 5% HS (HHS), or 2.5% CM-2.5% HS (HCH) was tested for 6 weeks. Body weight gains, obesity indexes, and body fat contents in the experimental groups (HCM, HHS, HCH) were decreased compared with HF group. The levels of serum triglyceride, total lipid, total cholesterol and LDL-cholesterol in the experimental groups were markedly decreased, however HDL-cholesterol levels in the experimental groups were slightly increased compared with HF group. In addition, although serum ALT and AST activity, and relative organ weights were lower than those of HF group, serum albumin contents were not significantly different in all experimental groups including the normal control group (NC). In conclusion, there are improved effects on obesity in the obese model of animals with all experimental diets supplementations, and the improvement degrees on obesity depend on the content and compositions of the herbal medicine mixture. Further study is needed on the anti-obesity mechanism of these diets.

To examine the combined effects of a high-protein diet and aerobic exercise on body weight and composition and blood lipid profiles in overweight women, 30 young women were recruited and placed into three groups: The high-protein diet and exercise group (HPE), the exercise-only group (EXO) and the control group (CON) (30$\pm$3%, 27$\pm$2%, and 29$\pm$3% body fat, respectively) for an 8-week experimental period. Daily diet included 25% isolated soybean protein (>90% protein, approximately 400 kcal) combined with each subject s usual diet for the HPE group. The exercise program consisted of aerobic-type exercises undertaken >3 times/wk and for>30 min/session at 50-60% of maximal capacity. Physical fitness, body composition, serum total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), triglycerides (TG) and glucose were measured before and after the experiment. Maximal aerobic capacity increased by the end of experiment in both the HPE (from 27.2$\pm$3.5 to 35.l$\pm$5.9 ml/kg/min, p<0.01) and EXO (from 30.3$\pm$5.4 to 33.8$\pm$3.8 mㅣ/kg/min, p<0.05) groups. Percent body fat decreased by 3.3% (p<0.01) in the HPE group and by 1.5% (p<0.05) in the EXO group by the end of the experiment, but not in the CON group. Lower back strength and agility increased only in the HPE group. In the HPE group, TC decreased from 168$\pm$20 to 155$\pm$18 mg/dL and HDL-C increased from 57$\pm$l0 to 61$\pm$9 mg/dL in HPE (p<0.01). But TC and HDL-C did not change in the EXO and CON groups. TG and glucose did not vary among the groups. Although the EXO group showed a similar outcome to that of the HPE group, a favorable change in body composition and blood lipids as well as an improvement in aerobic capacity was more marginal in the latter group.

Regular long term dance movement could be one of ways to induce improvement of psychophysiological variables, resulting in improvement of quality of life. However, there have been few studies to evaluate the effect of dance movement training on both physiological and psychological variables in the elderly. This study was focused to determine the effect of Korean traditional dance movement training on psychophysiological variables-body weight, body fat, lean body mass, muscle strength, muscle endurance, flexibility, agility, resting heart rate and blood pressure, depression and life satisfaction-in Korean elderly women. Thirty four subjects, aged between 65 and 75years who have normal cognition, sensory function, cerebellum function, cardiovascular function, participated in this study. Seventeen experimental group subjects were selected from E-elderly university in Kyung Gi province, and Seventeen control group subjects were selected from N-welfare facility in Seoul City. Seventeen experimental group subjects participated for 12weeks dance movement program. Korean traditional dance movement program was developed on the basis of Korean traditional dance and music by the author. The program consisted of approximately 50minutes of dance, 3times a week for 12weeks. During 50minutes workout, there were 15minutes of warm-up dancing, 25minutes of conditioning dance and 10minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. The body weight, body fat, lean body mass, muscle strength(grip strength, leg strength), muscle endurance, flexibility, agility, resting heart rate and blood pressure, depression and life satis-faction were measured prior to and following the experimental treatment. The participants in dance movement were interviewed focusing on subjective feeling following 12 week's regular dance movement. Data were analyzed with mean, standard deviation, percentage of change, X²-test, t-test, and ANCOVA test using SPSS PC/sup +/ program. Subjective feeling was categorized into cognitopsy-chological and physiological responses. Results were obtained as follows : 1) The body weight (F=15.52, p=.000), body fat (F=18.33, p=.000) and lean body mass (F=7.28, p=.011) of the experimental group were significantly lower than those of the control group following the dance movement training. 2) The leg strength (F=30.96, p=.000), muscle endurance (F=9.06, p=.005), agility(F=44.92, 000), flexibility(F=6.84, p=.014) of the experimental group were significantly higher than those of the control group following the dance movement training. There was no significant difference of grip strength(F=.43, p=.515) between experimental and control groups. 3) The heart rate(F=26.96, p=.000), systolic (F=10.40, p=.000) and diastolic(F=3.99, p=.005) blood pressure at rest of the experimental group were significantly lower than those of the control group following the dance movement training. 4) No significant difference of score of depression (F=3.49, p=.071) was observed between experimental and control groups. 5) Score of life satisfaction of experimental group was remarkably higher than that of control group following 12weeks of dance movement training (p<0.05). 6) Thematic responses about the dance movement following the training were positive. "I feel good" was the most frequent among cognitopsychological responses and "I feel lightness of body" was the most frequent among physiological responses. The results suggest that Korean traditional dance movement training can improve psychophysiological variables of Korean elderly.

This study was performed to examine the combined effects of L-carnitine and isoflavone supplementation on weight reduction and body fat distribution in overweight women. Overweight/obese women (body mass index > $23kg/m^2$) who were not diagnosed any type of diseases were included in this study and sixty subjects ($41.1{\pm}1.5$ years, $25.9{\pm}0.3kg/m^2)$ were randomly assigned to a placebo (n=30) or a supplement group (n=30, L-carnitine 300 mg+isoflavone 40 mg/day). We measured anthropometric parameters, abdominal fat distribution by computerizd tomography and blood components before and after the 12 week intervention period. After the 12 weeks of supplementation, subjects in L-carnitine and isoflavone supplement group showed a significant reduction of body weight (p < 0.001), body fat % (p < 0.05), and waist to hip ratio (p < 0.01) whereas placebo group did not show any changes. In a CT-scanned results, total fat area at L4 level was significantly reduced by 8.1% (p < 0.01) with the reduction of visceral fat area (-11.1%, p < 0.001) and subcutaneous fat area (-7.0%, p < 0.05) in the supplement group. The supplementation of L-carnitine and isoflavone showed the significant improvement of HDL-C (p < 0.01) and apoB (p < 0.05) concentrations, however, change values in those markers were not significant compared with those of the placebo group. In addition, a significant increase of adiponectin level (p<0.001) was observed in the supplement group after the intervention. The result of present study demonstrated that supplementation of 300 mg L-carnitine and 40 mg isoflavone per day fur 12 weeks can give beneficial effects on weight reduction and visceral fat accumulation. These potential antiobesity supplement can produce more favorable effects when combined with lifestyle modification.

Chromium has emerged as an essential trace mineral in nutrition. However, it readily causes toxicity because of slightly excessive dose and/or form of chromium supplement. Therefore, developing a noble form of chromium supplement which is capable of not only an increased availability but also a reduced toxicity has been a critical issue in chromium nutrition. Chromium-methionine chelate has been, so far, one of the latest developments in its kind. Although not much information is available for the chromium-methionine chelate, especially in view of animal performances upon dietary supplementation, several studies indicated chromium methionine chelate could be effective to improve meat quality by increasing muscle mass but decreasing body fat. Highly-graded beef was produced by dietary chromium methionine supplementation during fattening stage of Korean native steers. Body muscle was increased in replace of decreasing body fat in both pig and rat that were dietary supplemented with chromium methionine chelate. However, a pig farm study did not show any significant improvement of body gain upon supplementation of chromium methionine. Immune responses of pig and rat were not always dependent upon chromium form but were varied by species. These results suggest there could be a different mode of responses due to species as well as onset time of dietary supplementation of chromium methionine. It is still early to conclude the bio-efficacy of chromium methionine chelate presumably due to its recent appearance into the field. But the chelate is certainly worth more application to animal since it certainly reduced the application level of dietary chromium.

The aim of this study researchs status of the nutrient intake between male and female students and the nutrient intake by BMI. This study was done to investigate the body composition and nutrient intakes of 340 college students (170 males, 170 females) in Gyeonggi area. Weight, height, BMI, and blood pressure of these college students were measured Nutrient intake was assessed using the 24-hour recall method, and then calculated using the nutritional evaluation program [CAN Pro 2.0 professional (Korean Nutrition Society, 2002)]. Average height and weight were 176$\pm$5.1 cm, 70.60$\pm$l.l kg in male students and 162.2/$\pm$4.5 cm, 54.4$\pm$7.7 kg in female students respectively. Subjects were divided into three groups by BMI: underweight (less than 18.5), normal weight (18.5 to less than 23), and overweight (more than 23). The ratios of male and female subjects among these groups were 5.3% and 17.6% in underweight, 50% and 65.3% in normal weight, and 44.7% and 17.2% in overweight. Systolic and diastolic blood pressures were 124.0$\pm$1.5 mmHg and 76.1$\pm$14.8 mmHg in males and 1l0.l$\pm$12.9 mmHg and 70.l$\pm$10.8 mmHg in females, all in the normal range. Using nutrient values of the 7th Recommended Dietary Allowanes, the nutrient intake was calculated to Korean RDA (%). Nutrients below 75% Korean RDA were Calcium, Vitamin $B_2$, and Folate and nutrients above 100% RDA were Protein, Fe, Phosphorous, and Vitamin $B_6$. BMI showed positive correlations with body fat (%)(p<0.01) and WHR (p<0.01). Nutritional education is desirable for the improvement of dietary behaviors, body composition and nutrient intake of college students.
