Objectives : To identify the effect of Taeyeumjowee-tang on the treatment of obesity Methods : After having been fed a high-fat diet for 6 weeks, obese white rats were classified into three groups. Control group 1 was fed a high-fat diet for 2 more weeks. Control group 2 was fed a normal diet for 2 weeks. The Sample group was fed Taeyeumjowee-tang extract with a normal diet for 2 weeks. The result of the comparison among the three groups was as follows. Results : The Sample group decreased significantly as compared with the Control 1 and 2 groups in changes of the body weight, fat cell size, fat accumulation, insulin, triglyceride, total cholesterol, total lipid, free fatty acid and UCP1. Conclusions : Taeyeumjowee-tang has significant effect on the treatment of obesity resulting from a high-fat diet. Especially, it was a sure remedy for Control group 2 that was fed normal1y after having a high-fat diet.

We are concerned about how to apply the theories of oriental medicine appropriately, which direction should it be taken, and how it should be developed. And it is believed to be essential for the government to make efforts to set a standard and laws to validate the medicinal effects and process of the assessment so that the systematic development can be encouraged, and to prepare guidance for the food development for national health improvement Ihis study was peformed to provide basic data that predict the usefulness of oriental medicinal herbs to remove the dampness through diuresis for excess syndrome obesity with oriental diet therapy cuisine(Yak-Sun). Five oriental medicininal herbs, Coix lachryma-jobi L, Atractylodes lancea DC., Ligusticum wallichii F., Angelica sinensis D., Zingiber officinale R. were collected and made into mixing extracts(OMCE). And we examined the effects of OMCE on body weight serum glucose, insulin and lipid profile improvement in rats fed high fat diets. Sprague-Dawley rae(230-250 g) were randomly divided into five groups : basal diet(normal diet control group, NCG), only high fat diet(High fat control group, HCG), high fat diet and supplemented with 25mg/100g body weight 50mg/100g body weight 75mg/100g body weight by OMCE(HLG, HMG, HHG). These experimental diets were fed for 6 weeks. The OME fed groups decreased more significantly in weight serum glucose insulin and lipids than the high fat control group did. These results imply that the OMCE can be used as a safe and clinically applicable ingredients for diet called Yaksun of excess syndrome obesity in human.

This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.

Our purpose was to investigate the effect of a 5-week high-fat diet on the body weight, blood components [triglycerides (TGs), free fatty acids (FFAs), and glucose], and lipoprotein lipase (LPL) mRNA expression in the skeletal muscles of rats. Body weight increased overtime in experimental and control groups without significant differences. In terms of the blood components, the density of TG was significantly lower in the high-fat diet group compared to the control, whereas FFA and glucose levels were similar in the two groups. Although the levels of glyceraldehyde 3-phosphate dehydrogenase(GAPDH) mRNA expression were similar between the groups, LPL mRNA expression was significantly higher in the high-fat diet group than that in the control group. The results of this study suggest that a high-fat diet enhances LPL mRNA expression, as well as possibly increases fat metabolism. For a better understanding of the relationship between diet patterns and fat metabolism, further analysis of genes related to the fat metabolism is warranted.

The objective of this study was to compare the electrolytes contents in skeletal muscles of two different groups of rats, one for control fed 20% casein diet, and the other experimental group recovered from 7% casein diet as protein restriction feeding for two weeks at the beginning of this experiment. Two different comparison criteria were used in this study, one for comparison between animals at the same age groups and the other between groups weighing same body weight as the control groups. Food consumption of animals for experimental and control groups were ad libitum. Following measurement and samples were collected: body weight, five different muscles-anterior tibialis (A.T.) extensor digitorium longus (E.D.L.) soleus, plantaris, gastrocnemius-for electrolytes and protein analysis. The experimental groups showed lower body weight than that of control group. Same trend was showen in protein content in five different muscles. Magnesium and potassium content in four muscles except gastrocnemius showed lower and sodium higher in experimental groups than those in control group at fourteenth day, after recovery from protein restriction, electrolytes content change showed differently in four muscles. Magnesium and potassium contents were increased as protein content in diet. Sodium content decreased as one week intake of recovery diet started, thereafter it was rather slowly increased. Phosphorus content in gastrocnemius at the second week in experimental group was slightly lower than that of control group, and it recovered rapider while at the same body weight group it was higher in experimental group.

The nutritive value of rumen contents and barley mixture (4:1 w/w; RCB) was evaluated and the effect of their feeding on growth performances in Najdi lambs was studied. A metabolism trial was conducted with 16 rams divided into four dietary groups. The diets were: a whole-mixed control diet and three diets where RCB was incorporated at the rates of 25, 50 and 100%, replacing an equal amount of control diet. The results showed that there was a depression (p<0.05) in DM digestibility for the 100% RCB diet in comparison with other diets. The digestibility of CP was higher(p<0.05) for the 25% RCB diet as compared to the control diet; there was a trend for a small (p>0.05) decrease in digestibility as level of RCB increased. Lambs in all studied diets were in positive nitrogen balance; the differences between diets were not significant. A total of 45 lambs were allotted into three groups and used to evaluate the effect of dietary inclusion of RCB (0, 25 and 50%) on growth performance and carcass traits. Daily DM intake, final body weight, carcass weight and dressing percentage were not different among treatments. Average weight gain and ether extract (EE) in 9-11th control joint were higher (p<0.05) in lambs fed control diet than those fed RCB diets. The substitution of RCB for 50% of control diet exhibited 11.8% reduction in feeding cost for each kg of body weight gain.

Objectives : The aim of this study was to investigate the effects of Gamisaenggan-tang on high fat diet induced nonalcoholic fatty liver disease. Methods: Rats were randomly divided into four groups. The Normal group was fed a solid diet containing 10% fat. The Gamisaenggan-tang (GS) group was fed a solid diet containing 10% fat and Gamisaenggan-tang (90mg/100g body weight). The Control group was fed a solid diet containing 60% fat. The HFD-Gamisaenggan-tang (HFD-GS) group was fed a solid diet containing 60% fat and Gamisaenggan-tang (90mg/100g body weight). Six weeks later, rats body weight, liver weight, serum ALT, GGT, ALP levels were measured. Histological findings (Oil red O staining), hepatic triglyceride, TNF-${\alpha}$, and TGF-${\beta}$ levels in the liver tissue were studied. Results: Average body weight of the HFD-GS group was significantly less than that of the Control group. There were no significant liver weight differences among each group. The GGT levels of the HFD-GS group were significantly less than those of the Control group. However, there were no significant differences in the ALT or ALP levels among the groups. TNF-${\alpha}$ protein production assessed by western blot analysis was reduced by Gamisaenggan-tang. Greater fat accumulation was observed in the liver tissue of the Control group than in the HFD-GS group, which means the Gamisaenggan-tang has an inhibitory effect on the accumulation of fat in the liver. Conclusion : The results suggest that Gamisaenggan-tang can be potential candidate for the treatment of nonalcoholic fatty liver disease in clinics.

This study investigated the effect of weight control by using the commercial appetite suppressant ((-)-hydroxycitric acid(HCA) formula) and nutrition education on 72 obese women over a period of 8 weeks. During the study it conducted nutritional education for women to control their weight, thus analyzed their changes in anthropometric variables. All obese women were randomized in a double-blind method to consume either HCA(HCA group : experimental group) or placebo(placebo group : control group). Two groups were also divided randomly into 2 groups combined with commercial formula diet in 1 meal a day(HD group and PD group : HCA + gormula diet and placebo + formula diet) or not(HO group and conducted with 4 groups(HD, HO, PD, and PO group). All subjects were assigned to consume 800-1500kcal/d balanced diet which is 500kcal less than their usual energy requirement. To evaluate the effect of the weight control program, weight, percent of body fat, waist and hip circumferences, and 5 skinfold thickness were measured up to 5 times in all obese women. The mean weight of the subjects at the onset of the study was 76.5$\pm$10.6kg. The mean body mass index(BMI) wa 30.1$\pm$3.8 and it was in the upper 5 percentile of mean BMI of Korean women. At the end of the program, mean weight loss was 3.5kg after 2 weeks(p<0.001), and 5.8kg after 4 weeks(p<0.001). The waist, hip ratio(WHR) and skinfold thickness measurements of biceps, triceps, subscapular, suprailiac and abdominum showed significant reduction over the entire study period(p<0.05). These outcome were evaluated by effect of nutritional education and counselling. The reduction of % of body fat was significantly different among the 4 groups. Women who administrated HCA demonstrated more change in weight, BMI than the placebo group. There was also significant reduction in body composition (% of body fat, WHR, and skinfold thickness) than the other groups. The HD group which was administrated HCA combined with formula diet was more decreased than other groups. It showed that this program using commercial HCA and formula diet induced not only a change in weight but also a change in body composition. The outcome of this study suggests that HCA has a more effctive change on weight control which is carried out with nutritional education and counselling.

This study investigated the effect of raw soybean yellow(RSY) and raw soybean black(RSB) on body weights, pancreas weights, serum glucose and lipid concentrations of boty normal and diabetic male rats(Sprague-Dawley, body weight 338.8$\pm$19.2g). For each experimental, some rats were injected with streptozotocin intraperitoneal(i.P.) to induce diabets, and other rats were injected with buffer i.P. as a control group. Body weight gain(BWG) was lower in rats fed both RSY and RSB diet(3.4~5.0g BWG) than in those fed control diet(58.1g BWG). The diabetic rats showed significant decrease of bo요 weight (-50~-67g) compared with the control rats. RSY and RSB feeding resulted in greater pancreatic weight relative to body weight, and diabetic rats fed RSY and RSB had heavier pancreatic weights relative to body weight than control rats. The levels of fasting serum glucose in diabetic rats fed both RSY and RSB decreased by 42 and 31%, respectively, compared with the diabetic control rats, but they increased by 80 and 110% compared with the normal control rats. The concentrations of total lipid, triglyceride, phospholipid and total cholesterol in serum of diabetic rats fed RSB diet were lower than those in control rats, but serum HDL-cholesterol, HDL-cholesterol/total cholesterol ratio were not affected by raw soybeans feeding. Atherogenic index wa lower in diabetic rats fed RSY and RSB diet than those in control rats. The concentrations of total lipid, triglyceride and phospholipid in liver were lower in raw soybean groups than those in control group. The concentrations of cholesterol in liver of groups treated raw soybean were decreased compared with the control group.
