The effect of diets(high fat, high fat high energy, pectin, cellulose) on lipid metabolism were in 70 male rats for 8 weeks. The rats were assigned to either a control(C), high fat (HF) or high fat high energy(HFHE)group for 4 wks. During the next 4wks, reassigned to one of three treatments(high fat, pectin, cellulose) in the HF group and one of three treatment (hign fat high energy, pectin, cellulose) in the HFHE group. Therefore, the total treatment group became 7 (C, HF, HF-P, HF-C, HFHE, HFHE-P, HFHE-C). Parameters evaluated and compared for each diet were body weight, total energy intake, Feed Efficiency Ratio (F.E.R), total lipid, total cholesterol (TC), HDL-cholesterol(HDL-C), HDL-C/TC, triglyceride (TG), phospholipid in serum, and changes in liver and spleen. The results are surmmarized as follows ; 1. There were no signiticant differences in boby weight gain among the groups. 2. Total energy intake was higher in the C group than other groups. Feed Efficiency Ratio (F.E.R) was higher in the HFHE group than other groups. 3. There was no significant difference in the weight gain of liver (100g/B.W.) among the groups. However, the weight gain of spleen (100g/B.W.) was gigher in the C group than other groups (HF and HFHE). 4. Total lipid, TC, TG, and phospholipid increased significantly in all groups for the first 4 wks. However, after 8 wks, pectin and cellulose supplementation groups decreased significantly. Therefore, we can conclude that the HF and the HFHE diet led to increase lipids concentration and the pectin and the cellulose treatments decreased lipids concentration in serum. However, the pectin treatment had greater effect than the cellulose treatment.

This study was performed to verify the effects of corn husk powder on serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. Powder of corn husks has been used as a folk remedy from ancient times in Korea. In the case of corn husk measurement of TPC (p<0.05), ABTS+ radical scavenging activity of trolox (p<0.05), DPPH radical scavenging activity (p<0.05), and measured value of FRAP (p<0.0001) were higher in ethanol extract than water extract. Weight of livers was significantly higher in the control group and high-fat diet group compared to groups fed 10% and 20% corn husk powders with high-fat diet (p<0.0001). For blood HDL-cholesterol concentration, mice fed 10% corn husk powder with high-fat diet ($160.00{\pm}16.17mg/dL$) showed significantly higher levels compared with the other three groups (p<0.05). Mice fed 10% and 20% corn husk powders with high-fat diet showed high numerical values of $13.50{\pm}2.51$ and $11.25{\pm}2.87mg/dL$, respectively. For triglyceride concentration in blood, mice fed 10% ($83.50{\pm}19.30mg/dL$) and 20% ($88.50{\pm}22.25$) corn husk powder with high-fat diet showed very low levels compared to the control group and high-fat diet group. In the case of leptin, the high-fat diet group showed a significantly high level of $5.88{\pm}3.53ng/dL$. Groups fed 10% and 20% corn husks with high-fat diet showed low numerical values of $2.72{\pm}2.34ng/dL$ and $1.10{\pm}0.62ng/dL$, respectively (p<0.05). Corn husk powder increased high HDL-cholesterol concentration in blood while lowering triglyceride concentration and leptin secretion. Therefore, powder of corn husks has utility in the food industry and food processing.

In order to investigate the anti-obesity effects of Gambibang-2(here in after referred to GBB2) on the obese gene and obese inhibitory, C57BL/6 mice were induced by high fat diet. C57BL/6 mice were divided into four groups(normal, high fat diet with control, high fat diet with Reductil(here in after referred to RDT), high fat diet with GBB2 extract) and fed for 8 weeks. And observed that, body weight change, the weight change of the adipocytes in body and liver, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, glucose, leptin change in the serum, the expression of ${\beta}3AR$ and leptin gene in 3T3 cell and primary adipocyte cell, histological analysis of adipose tissue and liver tissue. GBB2 and RDT group showed that the revelation of ${\beta}3AR$ in primary adipose cell and 3T3 cell were increased considerably, and that the revelation of leptin in primary adipose cell and 3T3-L1 cell were decreased considerably. GBB2 and RDT group showed that the body weight were decreased considerably after 7-8 weeks. GBB2 and RDT group showed that the weight of adipocyte and liver were decreased. GBB2 and RDT group showed that the amount of HDL-Cholesterol were increased, the amount of glucose, LDL-Cholesterol and Triglyceride were decreased considerably. GBB2 group showed that the amount of leptin in the serum were decreased. GBB2 and RDT group showed that the size of adipocyte in adipocytes tissue and the adipose vacuoles in liver tissue were decreased. Taking all these observations into account, GBB2 considered to be effective in treating on the obese gene and obese inhibitory. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

This study was done to evaluate the nutritional status and the desirable time and period for making dietary records in male high school Taekwondo athletes. Nutrient and flood intake was investigated using dietary record method during usual training (UT, for 29 days) and special training (ST, for 17 days) periods in nine Taekwondo athletes. Nutrient intake by 7-d and 3-d dietary record were compared to the standard nutrient intake, which was computed from dietary record during total period of UT or ST. Total mean energy intake was 2278 kcal, 84% of RDA, and mean intakes of riboflavin, Ca and Fe were less than 77% of RDA. Mean intakes of energy, carbohydrate, protein, fat, cholesterol, thiamin, riboflavin, and P decreased during ST (p < 0.05 or p < 0.01). Mean intakes of vegetables and grains ware the highest in the two periods and following were beverages and instant floods in UT, and meats and fruits in ST. During ST, mean intakes of mushrooms, meats and their products, and instant floods decreased, and sugars and sweets increased (p < 0.05 or p < 0.01). The contribution of grains and their products, instant floods, and meats and their products to mean intakes of energy, carbohydrate, protein and fat were high. In snacks, the contribution of instant floods, breads and confections and beverages was high. During UT, cholesterol intake at weeks 1 and 3, and intakes of protein, fat, thiamin, riboflavin and niacin at week 4 by 7-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). Intakes of VA, Ca and Fe at week 1, and intakes of carbohydrates, cholesterol rind crude fiber at week 4 by 3-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). During ST, VC intake at week 5, and energy intake from carbohydrate and cholesterol intake at week 6 by 7-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). Cholesterol intake at week 7, and energy intake from carbohydrates and fat, and intakes of protein, fat, cholesterol and riboflavin by 3-d dietary record were different from their standard intakes (p < 0.05 o. p < 0.01). In conclusion, empty-calorie floods can be a main source of diet and snacks for Taekwondo athletes, and education about desirable nutrients and floods intakes is needed to help them control their weight. When investigating the nutritional status of Taekwondo athletes in the future, the 7-day or 3-day dietary record is desirable provided they are conducted in the milddle of each period artier distinguishing UT from ST period.

This study was conducted to investigate the dietary supplementation of fruiting body of Hericium erinaceus (HE) mushroom on lipid profiles of serum and histological changes of the liver in rats with high fat and cholesterol diet. Five-week old female Sprague-Dawley albino rats were divided into three groups of 8 rats each: The normal control diet (NC group), high fat and cholesterol diet (HFC group), and HFC diet supplemented with 5% fruiting powder of Hericium erinaceus (HFC+HE group). In the HFC+HE group, serum total cholesterol, low density lipoprotein, and triglyceride concentrations were significantly reduced compared with the NC group. Body weight gain of those in the HFC+HE group were lower than those in the HFC group; whereas HFC+HE had no effect on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. The enzyme activities related to the liver function, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and, alkaline phosphatase (ALP), were lower in the NC group than in the HFC group, but without significance. Feeding the mushroom increased the excretion of total lipid and cholesterol. A histopathological analysis showed that the those in the HFC group developed hepatic steatosis, whereas those in the HFC+HE group developed small fat droplet. In conclusion, these results suggest that 5% HE supplementation to HFC diet provided health benefits by acting on lowering atherogenic lipid profile in rats with high fat and cholesterol diet.

This investigation studied the relationship between Body Mass Index(BMI) and dietary intake, levels of serum lipid, lipoprotein(a) and plasminogen activator inhibitor-1(PAI-1) of 28.449 Korean adults(16.937 men, 11.542 women) from 1995 to 1999. The dietary assessment was conducted using 24-hour dietary records and food frequency questionnaires. During this five year study, the BMI normal-weight group, as a percentage of the annual test population, decreased from 68.0% to 60.2%, while the BMI overweight and obese groups collectively increased from 25.0% to 29.7%. The levels of serum total cholesterol (TC), LDL-cholesterol(LDL-C), Triacylglycerol(TG) and PAI-1 increased as the values of BMI increased, while the levels of HDL-cholesterol(HDL-C) and lipoprotein(a)(men only) appeared to decrease as values of BMI increased. The levels of daily energy intake also increased as values of BMI increased in both men and women. The obese group had significantly higher levels of carbohydrate, protein, fat(men only), and cholesterol intake than those of the normal-weight, underweight, and overweight groups. In men, BMI positively correlated with the levels of macronutrients and cholesterol intake(p＜0.001), % energy of protein, fat, and alcohol intake(p＜0.001), and the levels of serum TC, LDL-C, TG and PAI-1(p＜0.001), while BMI negatively correlated with % energy of carbohydrate intake, and the levels of Lp(a) and HDL-C(p＜0.001). In women, BMI negatively correlated with level of cholesterol(p＜0.01), fat(p＜0.001), alcohol intake(p＜0.05),% energy of fat (p＜0.001), % energy of alcohol intake and level of and HDL-C(p＜0.001). Subjects who had serum TC, LDL-C, HDL-C, and TG levels greater than the standard reference values(TC＞240mg/㎗, LDL-C＞130mg/㎗, HDL-C＞35, TG＞200mg/㎗) exhibited a higher intake of the three macronutrients, iron, calcium, meat, milk and fatty foods than those subjects who had serum lipid concentrations less-than-or-equal-to the standard reference values. Overall, there was positive correlation between the high risk factors of vascular disease variables, dietary intake, and BMI. Prevalence of hypertension and high blood sugar were increased as BMI increased, but the prevalence of hypertension is decreased as the year goes by. These findings showed that dietary intake, level of serum lipids and other vascular disease risk factors increased as BIM increased. Therefore, middle or upper class Korean adults who have high BMI should improve their eating habits. This involve reducing alcohol, animal fat, high carbohydrate foods, and overall food intake, and balancing intake in order to lower vascular disease risk factors, including obesity.

We investigated the effects of single and combined administrations of Lactobacillus species (L. plantarum, LP; L. gasseri, LG; L. casei, LC) on blood lipid metabolism and obesity in mice fed a high-fat diet (HFD). The mice were continuously supplemented with LP, LP/LG, or LP/LG/LC, along with HFD, for 12 weeks. The consumption of HFD led to significant increases in body weight, total cholesterol, and triglyceride levels compared to the normal control group. However, administration of LP, LP/LG, or LP/LG/LC to HFD-fed mice reduced body weight gain and showed a tendency to suppress the levels of total cholesterol, triglycerides, and LDL-cholesterol, while increasing HDL-cholesterol levels. The HFD group exhibited increased abdominal fat weight and larger adipocytes in the epididymal adipose tissue compared to the NC group. However, the administered probiotics led to a significant reduction in adipocyte size with decreasing tendency in abdominal fat weight compared with the HFD group. Additionally, the deposition of giant vesicular fat cells in the liver of the HFD group considerably decreased in the probiotic-administered group. Microbiome analysis revealed an imbalance in intestinal microbes in the HFD group, characterized by lower Bacteroidetes and higher Proteobacteria ratios. However, probiotic administration tended to restore the microbial distribution by controlling the abundance of Bacteroidetes and Proteobacteria, resulting in decreased Firmicutes/Bacteroidetes and Proteobacteria/Bacteroidetes ratios. These results suggest that single and combined administration of LP and other probiotics holds enormous potential in reducing obesity in HFD-fed mice as they regulate lipid metabolism, reduce adipocyte size, and restore the balance of intestinal microbes.

Objectives This study is to investigate anti-obesity effects of Banggihwanggi-tang-hap-yeonggyechulgam-tang (BY), an herbal formula, in high fat diet induced obese mice model. Methods Fourty five male C57Bl/6J mice were randomly assigned to normal group fed with normal research diet (Nor, n=9), high fat diet control group treated with water (Veh, n=9), high fat diet group treated with orlistat (Oris; n=9, Orlistat 40 mg/kg), high fat diet group treated with low concentraion BY (BYL; n=6, BY 0.87 g/kg) and high fat diet group treated with high concentration BY (BYH; n=6, BY 1.74 g/kg). Results Seven weeks later, antioxidative capacity, body weight, epididymal fat pad and liver weight, reactive oxygen species (ROS), peroxynitrite ($ONOO^-$), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol, triglyceride, high density lipoprotein (HDL), low density lipoprotein (LDL), superoxide dismutase (SOD), catalase, glutathione peroxidase (Gpx), heme oxygenase (HO)-1 and histology of liver were evaluated. In the BYH group, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis (3 ethybenzothiazoline-6-sulfonic acid) radical scavenging activity were more than L-ascorbic acid. Body weight gain were significantly less than Veh group. Epididymal fat pad and liver weight gain were significantly less than Veh group. ROS and $ONOO^-$ were significantly less than with Veh group. ALT and AST were significantly less than with Veh group. Total cholesterol, triglyceride and LDL were significantly less, HDL were significantly more than Veh group. SOD, catalase, Gpx, HO-1 significantly increased compared with Veh group. Injury on liver was lesser than Veh group. Conclusions It can be suggested that BY has anti-obesity effects in high fat diet induced obese mice model.

Purpose: The purpose of this study was to examine the effect of a 8-week dynamic yoga program on body composition and blood lipids in middle-aged post-menopausal women. Method: Twenty participants were allocated to the yoga group (YG, n=10) or the control group (CG, n=10). They were assessed for lean body mass, percent body fat, waist to hip ratio, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and triglyceride both before and after intervention. The yoga group participated in the program lasting $50{\sim}60$ minutes, five times a week for 8 weeks. Results: Unlike the control group, the yoga group showed a significant decrease in total cholesterol, low density lipoprotein cholesterol, percent body fat, and waist hip ratio after the yoga training. However, changes in lean body mass, high density lipoprotein cholesterol, and triglyceride level during the intervention period were not different between the yoga group and the control group. Conclusion: The 8-week dynamic yoga program could be adopted to prevent cardiovascular diseases in middle-aged post-menopausal women by promoting body composition & blood lipids.

Purpose: Obesity, a worldwide epidemic, is associated with insulin resistance, hyperlipidemia, hypertension, cardiovascular disease, and certain cancers. Many strategies, including natural alternative anti-obesity agents, are used widely to prevent obesity. This study examined the effects of silkworm hemolymph on the weight control of C57BL/6N mice fed with a high-fat diet. Methods: The mice were divided into five groups: normal group (N), high-fat diet group (HFC), high-fat diet and silkworm hemolymph (at dose of 1 mL/kg BW (HFS-1), 5 mL/kg BW (HFS-5) and 10 mL/kg (HFS-10) for 12 weeks. Results: After 12 weeks treatment, the administration of silkworm hemolymph decreased the final body weight significantly along with a decrease in the weights of epididymal fat and total fat. The plasma LDL-cholesterol concentration was significantly lower in the HFS-1, HFS-5, and HFS-10 groups than in the HFC group. In addition, the leptin level of the HFS groups was significantly lower than those of the HFC group without a change in the plasma insulin concentration. Conclusion: These findings suggest that the silkworm hemolymph may have the potential to prevent obesity.
