The aim of the present study is to elucidate the anti-obesity effects of Doenjang with and without salt in C57BL/6J mice. For the analysis, a total of forty mice were randomly divided into four groups: normal diet group (ND), high-fat diet group (HD), high-fat diet supplemented with 20% Doenjang group (DJ), high-fat diet supplemented with 20% unsalted Doenjang group (NS). During the study period, food intake and body weight were measured daily and weekly, respectively. The animals were sacrificed after 12 weeks. Body weight gain, epididymal fat pad weight and serum triglyceride levels of DJ group were found to be significantly lower than those of the HD and NS groups. Serum total-cholesterol levels of DJ and NS groups were significantly lower as compared to the HD group. There were significant decreases in plasma insulin and leptin levels in DJ group compared with the HD and NS groups. We did not observe any significant changes in the expression of hepatic lipogenic-related gene $PPAR{\gamma}$ among the HD, DJ and NS groups. However, ACC expression was found to be significantly decreased in DJ group. Lipolysis-related gene ($PPAR{\alpha}$ and CPT-1) expression was significantly higher in the DJ group as compared to HD and NS groups. In conclusion, the results of this study showed that Doenjang supplementation lowers body weight gain and improves obesity-related parameters.

The aims of this study were to evaluate the anti-obese effects of pine needle, black tea and green tea in rats and overweight people. Supplementation of 1, 2, 4 and 8% amount to the control diet of pine needle extract and mixture groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Supplementation of 1, 2 and 4% amount to the control diet of black and green tea extracts groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Anti-obese effect in body weight gain and visceral fat mass of mixture group was higher than in other groups. In human study, extracts mixture supplementation to overweight subjects significantly decreased both body weight and body fat compared with placebo control group. In vitro study, black and green tea extracts significantly inhibited both the pancreatic lipase and ${\alpha}-amylase$ activities dose dependently. In conclusion, the anti-obese effects of pine needle, black, and green teas in rats were found. In overweight human subjects, extracts mixture decreased body weight and body fat compared with placebo control group. Anti-obese effect in black and green tea groups might be from an decrease in carbohydrate and fat digestions via inhibition of pancreatic ${\alpha}-amylase$ and lipase activities in part.

We investigated the in vitro and in vivo anti-obesity effects of extracts from young Akebia quinata D. leaves, including hot water (AQH) and 80% ethanol (AQE) extracts. The inhibitory effects of AQH and AQE on lipid accumulation in 3T3-L1 cells were examined by Oil Red O staining. Compared to control, lipid accumulation was significantly reduced by 18.3% with the treatment upon AQE at a concentration of $5{\mu}g/mL$. The levels of intracellular triglycerides and free glycerol were also reduced by 52.8% and 9.1% at the same concentration of AQE. The in vivo anti-obesity effect of AQE was evaluated in terms of body and white adipose tissue weights in ICR mice. Experimental groups were divided into the following five groups: normal diet (ND), high fat diet (HFD), high fat diet with 60 mg/kg/day of Orlistat (HFD-RF), high fat diet with 200 mg/kg/day of AQE (HFD-AL), and high fat diet with 600 mg/kg/day of AQE (HFD-AH). Feeding of HFD for eight weeks resulted in significant increases in body weight as well as weight gain compared to the ND group. HFD-AH group showed reduced body weight, weight gain, epididymal white adipose tissue weight, and perirenal white adipose weight as compared to the HFD group. These results indicate that AQE supplementation might have beneficial effects on anti-obesity by inhibiting lipid accumulation.

The present study was carried out to investigate the antiobesity effects of Platycodon grndiflorum extract on body weight changes and serum lipid composition of rats fed high fat diet. The Platycodon grandiflorum has been widely used as a folk food in the Orient for many centuries. We had experiment with Platycodon grandiflorum extract in order to find cure effects for obesty. The changes of the body weights in Platycodon ggrandiflorum extract treatment group showed a decrease in comparison with control group. Weekly body weights of PG group are respectively 243.7$\pm$2.0g, 283.5$\pm$4.3 g, 310.5$\pm$6.5 g, 333.2$\pm$7.5 g, 361.0$\pm$10.4 g, 390.5$\pm$11.5 g, 436.0$\pm$11.8 g, 454.4$\pm$11.4 g, 484.4$\pm$10.1 g. Body weight of PC groups are decreased compared with those of control group, but the rates are not significant. Total cholesterol of PG group(77.2$\pm$3.3 mg/dl) is decreased by 7.0% compared with that of control group. Serum triglyceride of PG group(103.6$\pm$9.0mg/dl) is decreased by 21.1% compared with that of control group. Serum free fatty acid of PG group(630.1$\pm$45.9 $\mu$Eq/l) is decreased by 19.6% .compared with that of control group. Total lipid amount of PG group(393.6$\pm$23.7 mg/dl) is decreased by 9.1% compared with that of control group. The above results suggest that Platycodon grandiflorum extract could prevent or cure metabolic diseases by preventing hyperlipemia caused by high fat diet.

The effects of Flavonol contents from Ginkgo biloba leaf on anti-atopy activity have not rarely been verified. This study is to investigate the effects of flavonol on Th2 cytokine production in MC/9 mast cells. For this, flavonol was analyzed by ELISA and Real-time PCR. Analysis results showed that flavonol significantly suppressed production of Th2 cytokines(IL-13, MIP-1a) in a dose dependent manner. The mRNA expression of IL-4, IL-5, IL-13, TNF-a were effectively restrained by Flavonol at the concentration 25,50,$100{\mu}g/m{\ell}$. And decrease of expression of NFAT-1, c-jun protein was confirmed by western blot analysis. These results indicate that flavonol has effects of decreasing the Th2 cytokine production in the MC/9 mast cell causing inhibition of transcription factors such as NFAT-1, c-jun. Thus, we would like to brief that flavonol may have the applicability as therapeutic agent for atopic dermatitis.

We investigated the anti-obesity effects of the water extract from Orostachys japonicus in high-fat-fed mice. For the analysis, 24 mice were divided into four groups: normal (N) group, high-fat diet (HFD) group, high-fat diet supplemented with 2.5% O. japonicus (HFD-OJL) group, and high-fat diet supplemented with 5% O. japonicus (HFD-OJH) group. The body weight gain and food efficiency ratio increased with a high-fat diet, but significantly decreased in the HFD-OJ groups compared with those in the HFD group. Levels of serum triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in the HFD-OJH group. The adipocytes within the epididymal adipose tissue were found to have expanded in the HFD group. However, the adipocytes in the HFD-OJ groups were comparable to those of the N group. These results suggest that O. japonicus has potential as an anti-obesity agent by decreasing body weight and lowering the serum lipid levels in obese mice.

This study examined the anti-obesity effect of krill oil (KO) by regulating adipokines in a high-fat diet (HFD)-induced obese mouse model. The mice were fed a 60 kcal% HFD for 16 weeks, and KO was then administered at an oral dose of 100, 200, and 500 mg/kg/day for four weeks before the end of the experiment. The administration of KO at concentrations of 200 and 500 mg/kg/day decreased body weight gain significantly compared with the HFD-fed control group. In addition, the HFD-fed control group showed the abnormal release of adipokines by an increase in leptin and decrease in adiponectin, compared to the normal diet-fed normal group. On the other hand, KO (500 mg/kg/day)-administered group attenuated the abnormal release of adipokines by the down-regulation of leptin and the up-regulation of adiponectin. Therefore, KO could be a promising therapeutic agent for obesity by the regulation of adipokines.

Consumption of high fat diet (HFD) induces obesity by accumulating triglycerides and inflammation in the body. In the present study, we investigated the effects of black onion vinegar (BV) on HFD-induced C57BL/6 obese mice model. The HFD-fed obese mice were administered black onion juice (BJ) and BV, respectively, for 6 weeks. The HFD-fed group increased body and organ weights compared with normal control diet-induced group. However, administration of BV significantly reduced body and organ weights compared with HFD-fed group. The BJ- and BV-administered groups improved the serum lipid profiles such as total cholesterol and triglyceride, compared with HFD-fed group. In addition, BV-administered group significantly improved serum high-density lipoprotein cholesterol and low-density lipoprotein cholesterol. The BV-administered mice had increased the number and size of adipose cells in the liver and adipose tissues. The administrations of BJ and BV significantly down-regulated adipogenesis transcription factors and proinflammatory proteins in the liver compared with HFD-fed group. In particular, BV-administered group showed stronger attenuation of adipogenesis-related proteins than the BJ-administered group. Therefore, this study demonstrated that administration of BV attenuated HFD-induced obesity, in particular down-regulation of adipogenesis, and it could be developed as a functional vinegar for anti-obesity.

Among the oriental medicine compounds, sulfur is known as a heat-generation material in a human body. Heat-generation reaction results in the consumption of energy source. Some oriental herbs are used to treat obesity and blood lipid composition. Therefore, we hypothesized that a sulfur containing oriental medicine compound, called as Hangbisan, could help weight loss of experimental rats. This study was designed to observe the change of weight of Sprague-Dawley (SD) rats that had been fed with high-fat diet containing 10% cellulose or Hangbisan for 9 weeks. Hangbisan affected the weight loss of rats as reducing the level of plasma cholesterol and triglyceride and increasing the level of HDL-cholesterol. Thus, this study revealed Hangbisan have an anti-obesity effect and a potential role for anti-obesity agent in the application of oriental medicine compounds.
