Objective : Recently, obesity has increased at an alarming rate and is now a worldwide health problem. Natural dietary supplement, $CharmSlim^{(R)}$(C), is mixed pills, which consists of beans, black sesames, kelps, onions, adlay seeds, anchovies, pyogo mushrooms, green tea. Our study was performed to determine the weight-loss effects of natural dietary supplement, based on natural ingredients, in mice fed high-fat diet with an abundance of carbohydrates. Methods : Four groups of male ICR mice were fed different diets during 6 weeks: normal diet(NOR), high-fat (15%, w/w) diet(HF), high-fat supplemented with natural dietary supplement powdered 5%(C5) and 10%(C10) groups. We measured the changes of food intake, body weight and adipose tissues weights. Also we examined levels of lipid profiles in serum. Results : Body weight, liver weight and food efficiency ratio were significantly higher in the HF group than in NOR group. After 6 weeks of treatment, body weight, liver weight and adipose tissues weights (epididymal, perinephric, visceral and BAT) were significantly decreased in the C10 group when compared to the control HF group. The C10 group had markedly lower serum levels of total cholesterol and triglyceride when compared with HF group. Conclusion : These results demonstrate that this dietary supplement can suppress the increased lipid profiles, body weight and fat gains, thus could be considered as an effective adjunct in the treatment of obesity.

This study described the effect of levan (9-2,6-linked fructose polymer) feeding on serum lipids, adiposity and uncoupling protein (UCP) expression in growing rats. Levan was synthesized from sucrose using bacterial levansucrase. UCP is a mitochondrial protein that uncouples the respiratory chain from oxidative Phosphorylation and generates heat instead of ATP, thereby increase energy expenditure. We observed that 3% or 5% levan containing diet reduced serum triglyceride levels, visceral and peritoneal fat mass and induced the UCP expression in rats fed high fat diet in previous study. To determine whether the intake of low level of levan may have the hypolipidemic and anti-obesity effect, 4 wk old Sprague Dawley male rats were fed AIN-76A diet for 6 wk, and sub-sequently fed 1% or 2% levan solution for further 5 wk. Intake of 1% levan in liquid form reduced serum triglyceride and serum total cholesterol levels to 50% and 66% of control group, respectively. Although epididymal and peritoneal fat masses were not affected by levan feeding, visceral fat mass was lower in 1% levan group compared to control group. The expression of UCP2 mRNA in brown adipose tissue, skeletal muscle and hypothalamus and UCP3 mRNA in skeletal muscle were not changed by levan feeding, while the UCP2 mRNA in white adipose tissue was up-regulated by levan feeding. In conclusions, intake of low level of levan solution reduced serum triglyceride and total cholesterol, restrained the visceral fat accumulation and increased UCP expression in white adipose tissue in rats. This study suggests that hypolipidemic and anti-obesity effect of levan attributed to anti-lipogenesis and inefficeint energy utilization by up-regulation of UCPs.

Purpose : We investigated the hormonal control of OB gene expression and leptin secretion in cultured human visceral adipose tissue. Methods : Visceral adipose tissues were cultured for up to 48 hrs in modified Eagle's medium with varying concentration of hormones : Control(no hormone), bovine insulin(100 nM), Dexamethasone(DEX, 100 nM), growth hormone(GH, 40 ng/mL), insulin+DEX(100 nM each), insulin+DEX+GH(100 nM insulin and DEX, 40 ng/mL GH). Quantitative analysis of leptin mRNA was performed by competitive reverse transcription polymerase chain reaction, and leptin secretion in culture medium was measured by IRMA using a commercial kit. Results : The addition of dexamethasone to the medium significantly increased OB gene expression and leptin secretion(P<0.05). Unlike dexamethasone, insulin did not affect OB gene expression and leptin secretion. Both insulin and dexamethasone, at high concentration, significantly stimulated leptin secretion compared with basal values(P<0.05). Leptin gene expression was not significantly increased by GH treatment alone, however GH, in combination with high concentrations of insulin and dexamethasone, attenuated the stimulatory effects of high concentrations of insulin and dexamethasone. Conclusion : Insulin cannot increase leptin secretion without the presence of dexamethasone. The mechanism suggested is that insulin may increase leptin secretion in cytoplasm only after dexamethasone increases the expression of OB gene. Further studies are necessary to elucidate the mechanism of the action of insulin on leptin secretion after increasing OB gene expression by dexamethasone.

Here we study the anti-obesity effects of by-product from soybean on mouse fed high fat diet. The body weight gain, visceral and subcutaneous adipose tissue weight, liver and epididymal adipose tissue weight in freeze-dried soybean-soaking-water (SSW) powder fed group showed lower level than those in high fat diet (HFD) group by determining with weight measuring and histological methods. Also, histological analyses of the liver and fat tissues of SSW grouped mice revealed significantly less number of lipid droplets formation and smaller size of adipocytes compared to the HFD group. Moreover, the levels of total serum cholesterol, LDL-cholesterol and the atherogenic index were decreased in the SSW groups. Especially, in SSW group, the levels of phosphorylation of two lipid oxidation enzymes, adenosine monophosphate-activated protein kinase (AMPK) and acetyl-CoA carboxylasse (ACC) were elevated hence that may activate fatty acid oxidation. But AST and ALT levels were not changed in blood. By micro-CT analysis of abdomen, SSW groups significantly showed a tendency to decrease visceral and subcutaneous fats as well as fat-deposited areas compared to HFD group. Taken together, we suggest that soybean soaking water has a function in ameliorating obesity through inhibiting lipid synthesis as well as stimulating fatty acid oxidation.

Enzymatically modified isoquercitrin (EMIQ) is a mixture of quercetin glycodsides consisting of isoquercitrin and its ${\alpha}-glucosylated$ derivatives containing one to seven additional linear glucose moieties. The aim of this study was to assess whether or not EMIQ attenuates high-fat diet (HFD)-induced body weight gain and changes in plasma indices of obesity in mice. Male C57BL/6N mice were fed chow diet, HFD, and HFD containing 1.2% EMIQ for 10 weeks. EMIQ significantly (P<0.05) reduced body weight gain (-21%), total visceral fat-pad weights (-31%), and plasma levels of triglycerides (-17%), total cholesterol (-19%), and free fatty acids (-26%) in HFD-fed mice. EMIQ significantly increased protein kinase A (PKA) expression in the epididymal adipose tissue of HFD-fed mice. Expression of adipogenesis-related genes significantly decreased, whereas expression of fatty acid oxidation-related and thermogenesis-related genes increased in epididymal adipose tissue of EMIQ-fed mice compared with HFD-fed mice. These results suggest that the protective effects of EMIQ against HFD-induced adiposity in mice appear to be associated with PKA-mediated signaling cascades involved in adipogenesis, fatty acid oxidation, and thermogenesis in adipose tissue.

The purpose of this present study was to investigate the effects of long-term treadmill running and aged garlic extract supplementation on weight, adipose tissue mass, lipid profiles and oxidative stress after exhaustion in high fat diet-induced obese rats. Thirty male Sprague-Dawley rats (3 weeks old) were used as subjects. High fat diets were fed to all subjects for 6 weeks in order to induce obesity. The subjects were divided into five groups - N (normal diet group), HD (high fat diet group), E (exercise group), EA (exercise with AGE diet group) and A (AGE diet group). Aerobic exercise was performed through treadmill running and AGE at a dosage of 2.86 kg/g was administered to rats 30 min before every exercise for 4 weeks. After 4 weeks, all groups completed acute treadmill running (speed increasing gradually to 25 m/min, 15% uphill grade) until exhaustion. Immediately after exhaustive treadmill exercise, the weight, adipose tissue mass, lipid profiles and oxidative stress of the rats were assayed. At the end of 6 weeks of high fat diets, body weight and body weight gain were significantly higher in the high fat diet groups than in the normal diet group (p<0.001). At the end of treadmill exercise with AGE intake for 4 weeks, body weight gain, visceral and epididymal fat of the E and EA groups were significantly decreased compared to other groups (p<0.05). There were no significant differences in gastrocnemius and soleus. T-C, HDL-C, TG and LDL-C were not significant in any of the groups. TBARS was significantly lower in the A group than in the E group (p<0.05). These results indicated that body weight gain, visceral and epididymal fat decreased in the E and EA groups, and TBARS levels were lower in the A group than the E group. Regular aerobic exercise intervention with AGE supplementation may also modify the adipose weight and improve the oxidant stress in obese rats.

Fumigaclavine C (FC), an active indole alkaloid, is obtained from endophytic Aspergillus terreus (strain No. FC118) by the root of Rhizophora stylosa (Rhizophoraceae). This study is designed to evaluate whether FC has anti-adipogenic effects in 3T3-L1 adipocytes and whether it ameliorates lipid accumulation in high-fat diet (HFD)-induced obese mice. FC notably increased the levels of glycerol in the culture supernatants and markedly reduced lipid accumulation in 3T3-L1 adipocytes. FC differentially inhibited the expressions of adipogenesis-related genes, including the peroxisome proliferator-activated receptor proteins, CCAAT/enhancer-binding proteins, and sterol regulatory element-binding proteins. FC markedly reduced the expressions of lipid synthesis-related genes, such as the fatty acid binding protein, lipoprotein lipase, and fatty acid synthase. Furthermore, FC significantly increased the expressions of lipolysis-related genes, such as the hormone-sensitive lipase, Aquaporin-7, and adipose triglyceride lipase. In HFD-induced obese mice, intraperitoneal injections of FC decreased both the body weight and visceral adipose tissue weight. FC administration significantly reduced lipid accumulation. Moreover, FC could dose-dependently and differentially regulate the expressions of lipid metabolism-related transcription factors. All these data indicated that FC exhibited anti-obesity effects through modulating adipogenesis and lipolysis.

This study evaluated the effect of biocellulose and the diet formulation on reducing body weight gain of obese rats induced by high-fat diet for 10 weeks. Thirty male Sprague-Dawley rats were randomly assigned to high-fat diet group (OB-CON), high-fat diet group containing 5% biocellulose (OB-BIO), and high-fat diet group containing 5% dietary formulation (OB-DF). After feeding each diet for additional 10 weeks, body weight gains of OB-BIO and OB-DF groups were lower by 3.3 and 4.8%, respectively as compared with that of OB-CON group. Although not significant, measured values of the perirenal and visceral fat pads of OB-BIO and OB-DF groups were lower than those of the OB-CON group. The weight of interscapular brown adipose tissue did not show significant difference in all groups. The size of adipocyte in rats was lower in both OB-BIO and OB-DF groups. Thus, biocelluose and the diet formulation showed the anti-obesity effect.
