Objective : This study investigated the anti-diabetic effects of DM1, a herbal mixture with Atractylodis Rhizoma, Anemarrhenae Rhizoma, and Cinnamomi Cortex in high fat diet (HFD)-induced diabetic mice and the mechanism in C2C12 mouse skeletal muscle cells. Methods : The C57B/6 mice were fed high fat for 12 weeks, and then administrated DM1 extract (500 mg/kg, p.o.) for 4 weeks. The changes of body weight, calorie and water intakes, fasting blood glucose levels and the serum levels of glucose, insulin, triglyceride, HDL-cholesterol, AST and ALT were measured in mice. The histological changes of liver and pancreas tissues were also observed by H&E stain. C2C12 myoblasts were differentiated into myotubes and then treated with DM1 extract (0.5, 1, and 2 mg/㎖) for 24 hr. The expression of myosin heavy chain (MHC), PGC1α, Sirt1 and NRF1, and the AMPK phosphorylation were determined in the myotubes by western blot, respectively. Results : The DM1 extract administration significantly decreased the calorie and water intakes, glucose, triglyceride, AST and ALT levels and increased insulin and HDL-cholesterol in HFD-induced diabetic mice. DM1 extract inhibited lipid accumulation in liver tissue and improved glucose tolerance. In C2C12 myotubes, DM1 treatment increased the expression of MHC, PGC1α, Sirt-1, NRF-1 and the AMPK phosphorylation. Conclusion : In our results indicate that DM1 can improve diabetic symptoms by decreasing the obesity, glucose tolerance and fatty liver in HFD-induced diabetic mice, and responsible mechanism is might be related with energy enhancement.

A few clues about correlation between endoplasmic reticulum (ER) stress and mulberry (Morus alba) leaves were investigated in only the experimental autoimmune myocarditis and streptozotocin-induced diabetes. To investigate whether a novel extract of mulberry leaves fermented with Cordyceps militaris (EMfC) could suppress ER in fatty liver, alterations in the key parameters for ER stress response were measured in high fat diet (HFD)-induced obese C57L/6 mice treated with EMfC for 12 weeks. The area of adipocytes in the liver section were significantly decreased in the HFD+EMfC treated group as compared to the HFD+Vehicle treated group, while their level was higher in HFD+Vehicle treated group than No treated group. The level of the eukaryotic initiation factor 2 alpha ($eIF2{\alpha}$) and inositol-requiring enzyme 1 beta ($IRE1{\alpha}$) phosphorylation and CCAAT-enhancer-binding protein homologous protein (CHOP) expression were remarkably enhanced in the HFD+Vehicle treated group. However, their levels were restored in the HFD+EMfC treated group, although some differences were detected in the decrease rate. Similar recovery was observed on the ER stress-induced apoptosis. The level of Caspase-3, Bcl-2 and Bax were decreased in the HFD+EMfC and HFD+orlistat (OT) treated group compared to the HFD+Vehicle treated group. The results of the present study therefore provide first evidence that EMfC with the anti-obesity effects can be suppressed ER stress and ER stress-induced apoptosis in the hepatic steatosis of HFD-induced obesity model.

Background: Dietary fat has been suggested to be the cause of various health issues. Obesity, hypertension, cardiovascular disease, diabetes, dyslipidemia, and kidney disease are known to be associated with a high-fat diet (HFD). Obesity and associated conditions, such as type 2 diabetes mellitus and nonalcoholic fatty liver disease (NAFLD), are currently a worldwide health problem. Few prospective pharmaceutical therapies that directly target NAFLD are available at present. A Traditional Chinese Medicine, ginseng-plus-Bai-Hu-Tang (GBHT), is widely used by diabetic patients to control glucose level or thirst. However, whether it has therapeutic effects on fat-induced hepatic steatosis and metabolic syndrome remains unclear. Methods: This study was conducted to examine the therapeutic effect of GBHT on fat-induced obesity, hepatic steatosis, and insulin resistance in mice. Results: GBHT protected mice against HFD-induced body weight gain, hyperlipidemia, and hyperglycemia compared with mice that were not treated. GBHT inhibited the expansion of adipose tissue and adipocyte hypertrophy. No ectopic fat deposition was found in the livers of HFD mice treated with GBHT. In addition, glucose intolerance and insulin sensitivity in HFD mice was also improved by GBHT. Conclusion: GBHT prevents changes in lipid and carbohydrate metabolism in a HFD mouse model. Our findings provide evidence for the traditional use of GBHT as therapy for the management of metabolic syndrome.

Objective : Obesity is often defined as a condition associated with accumulations of excessive body fats which resulting from disorder of energy balance in term of energy intake and energy expenditure. Methods : The effects of natural mixture (T) for inhibition of lipid metabolism on the liver, epididymal fat pads and pancreatic zymogen granules of high fat diet (HFD) supplied rats were observed by histopathology and histomorphometry. Results : As results of HFD supply, severe steatohepatitis such as increases of mean diameters of hepatocytes and the percentages regions of fatty changes was detected. In addition, hypertrophy of adipocytes (increase of mean diameters of epididymal fat pads) was also detected with dramatic decreases of pancreatic zymogen granules at histopathological and histomorphometrical observations. However, theses steatohepatitis and hypertrophy of adipocytes induced by HFD supply were inhibited by treatment of 5 % and 10 % T (T5, T10), respectively. Well corresponded as the results of adipocyte hypertrophy and steatohepatitis, the decreases of pancreatic zymogen granules were also dose-dependently inhibited by T treatment as compared with HFD control, respectively. Conclusion : In conclusion, based on the results, it is considered that test materials, T5 and T10, will be showed hepatoprotective and anti-obese effects, may be directly and/or indirectly mediated by pancreatic zymogen granules because they dose-dependently inhibited steatohepatitis, hypertrophy of adipocytes and decreases of pancreatic zymogen granules induced by HFD supply, respectively.

Lipid lowering properties from three plant water extracts, Rosa rugosa, Crataegus pinnatifida and Polygonum cuspidatum, were tested by supplementing a 1% high-cholesterol diet with them in rats. Plasma triglyceride levels in Rosa fugosa, Crataegus pinnatifida and Polygonum cuspidatum groups were significantly lower compared to that of the control. by 29% , 24% and 47% respectively. hepatic trigylceride levels in Rosa rugosa and Crataegus pinnatifida groups were significantly lower compared to the control by 11% and 15% respectively. Hepatic HMG-CoA reductase activity in Rosa rugosa group was significantly greater compared to the control by 406%. Hepatic ACAT activity was significantly lower in Polygonum cuspidatum group compared to the control by 28%. by multiple regression results, only plasma cholesterol was associated significantly (p<0.05) with liver HMG-CoA reductase activity. Plasma cholesterol explained 12% of thevariance of the liver HMG-CoA redctase activity. In conclusion, we have showen that hot water extracts from Rosa rugosa, Crataegus pinnatifida and Polygonum cuspidatum lowered plasma triglycerides in rats fed on a high-cholesterol diet. Data suggests that these extracts could potentially prevent or treat hypertriglyceridemia induced by a high fat diet and fatty liver.

Objectives : Although the anti-obesity effect of Schizandrae Fructus water extract has been demonstrated, its underlying mechanism is still unclear. Therefore, we aimed to evaluate the anti-obesity effect of Schizandrae Fructus water extract through the p-AMP-activated protein kinase (p-AMPK), sirtuin1 (Sirt1), and peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling in 60% high-fat diet (HFD)-induced obese mouse model. Methods : Male C57BL/6 mice were divided into four groups. The Normal group was fed a normal diet and the obese groups were fed 60% HFD. Except for the Control group, the GG group was supplemented with 0.5% Garcinia gummigutta and the SCW group was supplemented with 0.5% Schizandrae Fructus water extract. After 6 weeks, obesity-related biomarkers in serum were measured and the expressions of protein for lipid-related factors in liver tissue were analyzed by western blot. Results : Treatment with SCW significantly down-regulated body weight compared to the Control group. SCW down-regulated levels of triglyceride and total cholesterol in serum and significantly increased p-AMPK, Sirt1, and PGC-1α in liver tissue. In addition, the expressions of fatty acid oxidation-related proteins such as peroxisome proliferator-activated receptor α (PPARα), carnitine palmitoyltransferase 1A (CPT-1A), uncoupling protein 1 (UCP1), and uncoupling protein 3 (UCP3) were significantly up-regulated. However, fatty acid synthesis-related proteins including sterol regulatory element-binding protein-1 (SREBP-1), phospho-Acetyl-CoA Carboxylase (p-ACC), and fatty acid synthase (FAS) were significantly down-regulated. Conclusions : Taken together, SCW treatment showed anti-obesity effect by regulating both fatty acid oxidation-related and fatty acid synthesis-related proteins through AMPK/Sirt1/PGC-1α signaling in 60% HFD-induced obese mice.
