The study was conducted to investigate the effects of dietary calcium and soy isoflavone on body fat and lipid metabolism in high fat-induced obesity. Four week old female C57/BL6J mice, known as a good model of diet-induced obesity, were fed low Ca and high fat diet for 6 weeks. After induced obesity, mice were divided into six groups according to diets varying calcium contents (0.1 or 1.5%) and genistein contents (0 or 500 or 1,000 ppm). Body weight, fat pad (perirenal fat and parameterial fat), adipocyte size, serum total lipid and total cholesterol were significantly decreased by both high Ca intake and genistein supplementation. However, the effect of genistein supplementation showed in low Ca-fed groups. Serum LDL-cholesterol and TG were significantly decreased by high Ca intake and genistein supplementation, respectively. In liver, lipogenic enzymes (fatty acid synthase and malic enzyme) activity and TG were significantly decreased by both high Ca intake and genistein supplementation. This inhibitory effect of genistein on lipogenic enzymes showed in low Ca-fed groups. But liver total cholesterol and total lipid were significantly decreased by high Ca intake and genistein supplementation, respectively. Fecal excretion of total lipid, total cholesterol and TG were significantly increased by high Ca intake, not by genistein supplementation. In conclusion, high calcium intake and genistein supplement may be beneficial for suppression of obesity through direct anti-adipogenesis by decreasing fat weight and size and indirect anti-lipo-genesis by inhibiting lipogenic enzymes activity and improving lipid profile.

The fermentation of medicinal herbs facilitated by microbes is assumed to exert promising therapeutic efficacy on the absorption, bioavailability, and pharmacological effects by speeding up the making or conversion of active constituents into their metabolites. We examined the cardioprotective potential of fermented ginseng, GBCK25, against high-fat diet (HFD)-induced metabolic and functional illnesses as following the essential analysis such as electrocardiographic parameters, alterations of body and organ weights, and echocardiographic studies. The results exhibited that body weights were significantly reduced and the gain of different organ weights were partly eased by GBCK25 treatment. Echocardiography results proposed the amelioration of heart function through normalized levels of left ventricle systolic pressure, ejection fraction, and fractional shortening. These outcomes deliver straight confirmation that GBCK25 could be a potential nutraceutical source for the relief of HFD-induced obesity mediated cardiac dysfunctions.

Obesity increases the risk of mortality and morbidity because it results in hypertension, heart disease, and type 2 diabetes. Therefore, there is an urgent need for pharmacotherapeutic drugs to treat obesity. We performed a screening assay using natural products with anti-adipogenic properties in 3T3-L1 cells and determined that tschimganidine, a terpenoid from the Umbelliferae family, inhibited adipogenesis. To evaluate the anti-obesity effects of tschimganidine in vivo. Mice were fed either a normal chow diet (NFD) or a high-fat chow diet (HFD) with or without tschimganidine for 12 weeks. Treatment with tschimganidine decreased lipid accumulation and adipogenesis, accompanied by reduced expression of adipogenesis and lipid accumulation-related factors. Tschimganidine significantly increased the phosphorylation of AMP-activated protein kinase (AMPK) and decreased that of AKT. Depletion of AMPK relieved the reduction in lipid accumulation resulting from tschimganidine treatment. Moreover, tschimganidine administration drastically reduced the weight and size of both gonadal white adipose tissue (WAT) and blood glucose levels in high-fat diet-induced obese mice. We suggest that tschimganidine is a potent anti-obesity agent, which impedes adipogenesis and improves glucose homeostasis. Tschimganidine can then be evaluated for clinical application as a therapeutic agent.

As the obesity has been known to be related with the hyperlipidemia, cardiovascular disease, cerebral apoplexy, fatty liver, and other chronic diseases, recent researches have focused on the functional food materials and their anti-obesity activities. This study was performed to study the effects of vanilloid family capsaicin, major pungent ingredient of hot chillies and peppers, on anti-obesity activities. ICR male mice were fed one of the pellet diet, basal diet, and high fat diet with capsaicin (45 $\mu\textrm{g}$/day) solution for 5 days. Mice in the corresponding control groups were given water for 5 days. In results, capsaicin reduced body weights in any diet groups. Percent weight and cell size of the abdominal white adipose tissue in mice on the high fat diet with capcaicin were significantly lower compared with those in mice on the high fat diet with water. However, percent brown adipose tissue weight per body weight in mice on the high fat diet was not affected by capsaicin. Capsaicin reduced the levels of s-triglyceride and s-total cholesterol in the pellet diet or high fat diet groups. There was no difference in the s-protein levels between the capsaicin group and the control water group. These data indicate that 1) orally administered capsaicin has a reducing effect on the blood triglyceride and total cholesterol levels, and 2) capsaicin has lowering effects on the body weight, percent weight and cell size of the abdominal white adipose tissue.

Objectives : This study was performed to investigate the inhibitory effects of Cheongshimyeonja-tang water extracts(CSYJ) on high fat diet-induced obesity and hyperlipidemia in C57BL/6J mice. Methods : The experimental animals were divided into four groups; normal diet-fed control(ND), high fat diet-fed control(HFD), HFD+CSYJ 150 mg/kg(CSYJ 150), and HFD+CSYJ 300 mg/kg(CSYJ 300). Obesity with hyperlipidemia was induced by feeding high fat diet(40%), and CSYJ was administrated orally into mice every day for 5 weeks. The effect of CSYJ on the serological parameters for Obesity with hyperlipidemia was evaluated. Results : CSYJ-treated groups revealed significantly reduced body weight and feed intake, as well as feed efficiency ratio, compared to HFD-fed group in dose-dependent manner. CSYJ reduced significantly the serum levels of triglyceride, total cholesterol and LDL-cholesterol elevated by intake of high fat diet feed, while the increased serum levels of HDL-cholesterol attenuated levels of atherogenic index and cardiac risk factor. It also reduced the blood levels of insulin and leptin in HFD group, and inhibited lipid accumulation in organs such as liver and abdomal adipose tissue. Moreover oral administration of CSYJ decreased significantly the blood level of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and lactate dehydrogenase(LDH), and lipid peroxide(LPO), compared to HFD-fed group in dose-dependent manner. Conclusions : These results indicate that CSYJ could reduce high fat diet-induced obesity and hyperlipidemia, suggesting its clinical usefulness for declining body fat and hyperlipidemia.

Previous study showed that swimming improved obesity but was not through $PPAR{\alpha}$ activation in liver and skeletal muscle in high fat diet-fed female mice with functioning ovaries as an animal model of obese premenopausal women. Thus, this study was aimed at investigation of the effects of swimming on the promotion of health and its molecular mechanism in adipose tissue of high fat diet-fed female mice. Eight-week-old female C57BL/6J mice were randomly divided into two groups (a non-swim control group and a swim group, n=8/group). Mice in the swim group swam for 2 h daily for 6 weeks in water bath with temperature of $35{\pm}1^{\circ}C$. All the animals received high fat diet (45% kcal fat) for 6 weeks. Reverse transcription-polymerase chain reaction was used to elucidate the molecular mechanism. Female mice subjected to swimming had significantly decreased body weight gain and white adipose tissue mass compared with the female control mice. Histological studies illustrated that swimming decreases the hepatic lipid accumulation. As expected, swimming did not affect the expression of mRNA levels of peroxisome proliferator-activated receptor (PPAR) ${\alpha}$ and $PPAR{\alpha}$ target genes responsible for mitochondrial fatty acid ${\beta}$-oxidation, such as carnitine palmitoyltransgerase-1 and medium chain acyl-CoA dehydrogenase in the white adipose tissue. However, mice that underwent 6-weeks of swimming exercise had decreased the mRNA expression of lipogenic genes, such as sterol regulatory element-binding proteins-1C and fatty acid synthase in comparison to sedentary control mice, with decreased $PPAR{\gamma}$ target genes involved in adipocyte-specific marker genes, such as adipocyte fatty acid binding protein and leptin in the white adipose tissue. These results suggest that swimming can effectively prevent obesity induced by high fat diet-fed, in part through down-regulation of adipogenesis and lipogenesis in white adipose tissue of female obese mice. Moreover, these results suggest that swimming maybe contributing the promotion of health through regulation of adipogenesis and lipogenesis in overweight premenopausal women.

Herbal medicinal mushroom Cordyceps militaris has been traditionally used as tonic medicine for metabolic syndrome. Cordycepin, main extract of C. militaris, has been reported with immunomodulatory, anticancer, and hepatoprotective effects. This study was conducted to evaluate the potential hepatoprotective effect of cordycepin-enriched Cordyceps militaris, against high fat diet (HFD)-induced hepatic steatosis (HS) in male obese (ob/ob) mice. HFD was provided to ob/ob mice ad libitum (except negative control). Cordycepin-enriched C. militaris extract powder (CM) was orally administered once daily at dose levels of 0, 125, 250, and 500 mg·kg^-1 for 4 weeks. During the study, body weight gain was statistically increased in all HFD fed groups compared to negative control, but body weight gain in CM 500 mg·kg^-1 treated group shows a low tendency compared to HS model group. In organ weights, absolute and relative weights (to body weight) in liver and perirenal adipose tissue were increased in all HFD treated groups except CM 500 mg·kg^-1 treated group compared to the negative control. In clinical chemistry, serum glucose and total cholesterol levels in CM 250 and/or 500 mg·kg^-1 treated groups were lower than HS model group. In microscopical examination, hepatocyte vacuolation with macrovesicles in HS model group was increased compared to negative control, but this finding was decreased in CM 500 mg·kg^-1 treated group compared to HS model group. In this study, CM exhibited hepatoprotective effects against hepatic steatosis at mg·kg^-1 in ob/ob mice.

Objectives: Obesity is an important cause of insulin resistance that leads to obese type 2 diabetes. Recently it has been found that obesity is associated with adipose tissue accumulation which causes systemic inflammation. In this study, we investigated effects of Inula helenium on the inflammation in high fat diet-induced insulin resistance mouse. Methods: Insulin resistance was induced in C57BL/6 male mice (19~21 g) on a 60% fat diet. Mice were divided into 3 groups (n=6) of normal, control and Inula helenium. After 12 weeks, body weight, FBS, oral glucose tolerance test (OGTT), serum level of insulin, epididymal fat pad, liver weight and the gene expression of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, interleukin (IL)-10 and cluster of differentiation (CD) 68 were measured. Also, adipose tissue macrophage was analyzed by fluorescence activated cell sorting. Results: Inula helenium significantly reduces oral glucose tolerance levels, insulin serum level and adipose tissue macrophage. Also Inula helenium increased IL-10 gene expression and decreased CD68 gene expression. Conclusions: These results show that Inula helenium has anti-insulin resistance and anti-inflammatory effects on a high fat diet-induced insulin resistance mouse model.
