To investigate the efficacy of extract of Ginkgo Biloba seeds in high fat diet (HFD) in mice, the Ginkgo Biloba seeds extract (GSE) was orally administered to mice with a HFD at 300 mg/kg/day for 4 weeks. Our results show that GSE significantly inhibited fat accumulation. Moreover, GSE markedly reduced the final body weight with a decrease in epididymal adipose tissue mass and adipocyte size compared with the untreated HFD-induced group. Additionally, GSE ameliorated serum high-density lipoprotein cholesterol levels. The results show that Ginkgo Biloba seeds possesses hypocholesterolemic effect through down regulating lipid metabolism. Further studies are required in this area to strengthen the anti-obesity effects of GSE with active component, and it can be used a pro-drug instead of whole extract.

To investigate the efficacy of extract of Tartary buckwheat (F. tataricum Gaertn.) in high fat diet (HFD) in mice, the F. tataricum Gaertn. extract (FTE) was orally administered to mice with a HFD at 300 mg/kg/day for 4 weeks. Our results show that FTE significantly inhibited fat accumulation. Moreover, FTE markedly reduced the final body weight with a decrease in epididymal adipose tissue mass and adipocyte size compared with the untreated HFD-induced group. Additionally, FTE ameliorated serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels. The results show that Tartary buckwheat possesses hypocholesterolemic effect through downregulating lipid metabolism. Further studies are required in this area to strengthen the anti-obesity effects of FTE with active component, and it can be used a pro-drug instead of whole extract.

Anti-obesity effect of biocellulose and diet formulation containing it was evaluated using obese rats. Thirty male Sprague-Dawlely (SD) rats were randomly assigned to high-fat diet group (CON), high-fat diet group containing 5% biocellulose (BIO), and high-fat diet group containing 5% dietary formulation (DF). After 10 weeks, body weight gains of BIO and DF groups were reduced by 15.1 and 6%, respectively, as compared with CON group. Epididymus, parirenal, and visceral fat pads of BIO and DF groups were lower than those of CON group. Weight of interscapular brown adipose tissues increased slightly in BIO group and significantly in DF group. Size of adipocyte in rats decreased in BIO and DF groups. Results indicate biocellulose-containing diet has anti-obesity effect by reducing body weight gain and white adipocytes depots in rats fed high-fat diet.

Curcumin, a major polyphenolic compound of turmeric, is well known to prevent non-alcoholic steatohepatitis (NASH) related to obesity. The aim of the study was to investigate the effect of curcumin on hepatic fibrosis induced by carbon tetrachloride ($CCl_4$) in obese mice. $CCl_4$ was administrated in mice fed a normal diet (ND) or a high fat diet (HFD) for 7 weeks together with or without curcumin. It was conducted to examine for metabolic profiles, adipocyte size, and liver fibrosis by serum biochemistry, histology and immunohistochemistry. Also, Apoptosis of hepatic cells was determined by the TUNEL method. Treatment with curcumin significantly lowered the body weight, fasting glucose, serum AST and ALT, and decreased the adipocyte size, the number of macrophage and mast cells in adipose tissue, and collagen deposition in liver tissue in the HFD+$CCl_4$ group compared with the findings of the HFD+$CCl_4$ group. In contrast, treatment with curcumin on the ND+$CCl_4$ group did not show a significant difference except the body weight and mast cell number when compared with the ND+$CCl_4$ group. Furthermore, curcumin significantly reduced the number of parenchymal apoptotic cells, whereas it increased the number of non-parenchymal apoptotic cells, especially resembling an activated hepatic stellate cell in the liver. Taken together, this data suggests that curcumin might be an effective antifibrotic drug for the prevention of liver disease progression in obese mice. Thus, the development of curcumin as a therapy for obesity and liver fibrosis is supported.

E. japonica is a well-known medicinal plant in Japan. The leaves of E. japonica were reported to have a hypoglycemic action. However, seeds of E. japonica are discarded and not used. To elucidate for anti-diabetic effects of E. japonica, Type 2 diabetic mice were allocated to control group, E. japonica leaf, and seed extract group. Animals were fed a 2018S Teklad global 18% protein rodent diet. Animals were received daily oral injections of E. japonica leaf or seed extract at a dose of 200 mg/kg body weight for 6 weeks. Body weight, food intake and water intake, and total adipose tissue weight of animals were significantly reduced by feeding of E. japonica leaf extract. All E. japonica extract groups significantly decreased fasting blood glucose, glycosylated hemoglobin levels, size of adipocytes and serum adiponectins. However, they did not have a beneficial effect on the serum triglyceride and cholesterol in the diabetic animals. These results suggest that E. japonica seed and leaf extracts have a antidiabetic effect by controlling of blood glucose and decrease of size of adipocytes in db/db mice and seed extract is more effective in hypoglycemic action than leaf extract.

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.

Ginseng and probiotics have anti-obesity effects in mice fed a high-fat diet (HFD). Absorption of ginsenoside and colonization of probiotics occur in the intestine. In this study, a mixture of fermented ginseng and two probiotics, Bifidobacterium longum BORI and Lactobacillus paracasei CH88, was administered to HFD-fed mice for 9 weeks. The mixture significantly suppressed weight gain (p < 0.05, n = 8) and lipid deposition in the liver and adipose tissues as well as increased the mice's food intake. The adipocyte size of the adipose tissue was significantly decreased in the mixture-fed group, especially when 0.5% fermented ginseng and $5{\times}10^8/ml$ of the two probiotics were used (p < 0.05, n = 10). The expression of TNF-${\alpha}$ in adipose tissue was efficiently downregulated in the mixture-fed group (p < 0.05, n = 4). The supplement also improved the mice's fasting blood glucose levels (p < 0.05, n = 8) and total cholesterol feces excretion (p < 0.05, n = 8). The mixture of fermented ginseng and B. longum BORI and L. paracasei CH88 could have an anti-obesity effect and suppress lipid deposit in the liver and adipose tissues.

This study investigated whether increased adiposity is prevented by estrogen replacement in female ovariectomized (OVX) C57BL/6J mice, an animal model of human menopause and whether these metabolic changes reflect the inhibitory action of estrogen on peroxisome proliferator-activated receptor $\gamma$ ($PPAR{\gamma}$)-regulated gene expression. Treatment of $17{\beta}$-estradiol for the last one week of the experiment decreased high fat diet-induced body weight gain and white adipose tissue mass compared to OVX control mice. Histological analysis showed that administration of $17{\beta}$-estradiol to mice decreased the size of adipocytes in parametrial adipose tissue versus OVX control mice. In addition, $17{\beta}$-estradiol reduced the adipose expression of $PPAR{\gamma}$ as well as $PPAR{\gamma}$ target genes such as adipocyte fatty acid binding protein and tumor necrosis factor $\alpha$. These results suggest that $17{\beta}$-estradiol may inhibit adiposity through reducing the $PPAR{\gamma}$ activities in female OVX mice.
