  • Salicornia herbacea L. is an annual herb that grows in salt marshes and salt fields along the seashores. It is also commonly used as a folk remedy in Korea. The objective of this study was to investigate the beneficial effects of Salicorrnia herbacea L. (SH) hot water extract on obesity. Five-week old male Sprague-Dawley rats (n=36) were divided into two groups and provided either a normal fat diet (11.5% fat from kcal) or a high fat diet (40.5% fat from kcal) for 6 weeks to induce obesity. Then, rats were blocked into six groups of six mice each and provided either a diet containing SH (0.5% of diet; g/kg) or a normal diet for another 6 weeks. Final body weights were significantly reduced when rats were fed SH among the high fat diet groups (HNS and HHS). Serum triglyceride concentrations significantly decreased in every group provided SH. HDL-cholesterol concentrations significantly increased in SH-fed groups among the high fat diet groups. Further, atherogenic index significantly decreased when rats were fed SH diet (HHS). There were no differences in LDL-cholesterol between the high fat diet groups, and glucose concentrations decreased when rats were fed SH diet (HNS). These results indicate that dietary intake of Salicornia herbacea L. hot water extract might have beneficial effects on obesity by reducing body weight, fat weights, and improving blood lipid profile.

  • The study aimed to investigate the anti-obesity effects of 1% Rhus verniciflua vinegar (RV) supplementation in high-fat-diet (60% fat)-induced obese rats. A total of 50 4-wk-old male Sprague-Dawley rats were fed normal chow diet or maintained on high-fat diet (HFD) for 12 weeks to induce obesity and were then randomized into five groups as follows: normal diet+ultra-pure water (CON), HFD+ultra-pure water (OB-DW), HFD+1% acetic acid (OBAA), HFD+1% RV (OB-RV), and HFD+0.1% caffeine (OB-CF). AA was used as a control for RV, and caffeine was used as a positive control due to its weight reducing effect. After 2 months, body weight, organ and adipose tissue weights, serum lipids, hepatic lipids, adipocyte size, and cell number per spot level were analyzed. As a result, food efficiency ratio, abdominal adipose tissue weight, serum levels of total cholesterol, triacylglycerol, free fatty acids, coronary artery index, and fecal lipid were significantly reduced in the RV treatment group. In this study, we found that dietary RV improved obesity by increasing lipid excretion and reducing lipogenesis. These results suggest that RV has potential as a functional anti-obesity food.

  • Mast cells are major effector cells associated with allergic responses. They are activated through the release of histamine, arachidonic acid, and proinflammatory cytokines. We investigated the effect of nodakenin, derived from the roots of Angelica gigas Nakai, on mast cell degranulation and on an allergic response in an animal model. We also investigated the effect of nodakenin on expression of multiple cytokines. Nodakenin suppressed the release of ${\beta}$-hexosaminidase, a marker of degranulation, as well as the expression of interleukin IL-4 and TNF-${\alpha}$ mRNA. Nodakenin inhibited the passive cutaneous anaphylaxis (PCA) reaction in ICR mice in a dose-dependent manner. These results suggest that nodakenin can inhibit mast cell degranulation through the inhibition of IL-4 and TNF-${\alpha}$ mRNA expression, and that nodakenin may potentially serve as an anti-allergic agent.

  • The present study was conducted to evaluate the effects of various extracts of Hizikia fusiforme on the anti-obesity effects in 3T3-L1 preadipocytes. We used H. fusiforme extracts from ethanol (EEHF), dichloromethane (CFHF), ethyl acetate (EAFHF), butanol (BFHF), and water (WFHF). Treatment with these extracts significantly suppressed terminal differentiation of 3T3-L1 preadipocytes in a dose-dependent manner as confirmed by a decrease in lipid droplet content through Oil Red O staining; this effect was higher in WFHF than in other extracts. The concentrations of cellular triglyceride were also reduced in 3T3-L1 cells by exposure with these extracts, especially when compared with the controls. Treatment with 200 ${\mu}g/ml$ of WFHF and CFHF caused approximately 42.6% and 23.7% reduction, respectively. In addition, the extracts of H. fusiforme significantly reduced the expression levels of key pro-adipogenic transcription factors, including peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) and CCAAT/enhancer binding proteins ${\alpha}$ (C/$EBP{\alpha}$) and C/$EBP{\beta}$ as compared with controls. Accordingly, our data indicated that WFHF has a preeminent effect on inhibition of adipocyte differentiation among various extracts, and H. fusiforme extracts may be an ideal candidate for obesity relief.

  • This study investigated the anti-obesity effects of lactic acid bacteria ferments cultured in industrial medium with ethanol extract of ramie leaf (Boehmeria nivea L.). On the 4th day of fermentation, the maximum live cell counts were 8.75-8.85 log CFU/mL, pH was 3.74-3.79, and total acidity was 2.07-2.19%. The fermentation of lactic acid bacteria on the fourth day resulted in the amount of lactic acid reaching 1,676.03-1,910.12 mg%. The lipase inhibitory activities of Lactiplantibacillus plantarum (L. plantarum) JBLAB0101 (FRLPLA) and Lactobacillus rhamnosus GG (LGG, (FRLLGG)) ferments were 30.10%, and 25.63%, respectively, at a concentration of 0.5 mg/mL. The lipid accumulation, leptin production, PPAR-γ and SREBP-1c mRNA levels were decreased to 37.54%, 54.64%, 24.18%, and 31.32%, respectively, at 200 ㎍/mL concentration of FRLPLA. These results suggest that anti-obesity effect could be increased by lactic acid bacteria in industrial medium with extract of ramie leaf.

  • This study was performed in order to investigate the anti-obesity effect of Polygala tenuifolia on lipid mechanism in 3T3-L1 adipocytes. The chemical composition of the P. tenuifolia was analyzed in order to assess its nutritional value. Total dietary fiber was the highest among the proximate component of the P. tenuifolia. These results showed that the P. tenuifolia may be used as a potential functional ingredient for anti-obesity effect. Intracellular lipid droplets in the adipocyte were stained with oil-red O dye and quantified. In comparison to the control, lipid accumulation was significantly decreased by 40.1% and 22.4% when treated with the water extract and 70% EtOH extract of the P. tenuifolia at the concentration of $10{\mu}g/mL$, respectively. The anti-adipogenic effect of the water extract was stronger than that of the 70% EtOH extract. The gene expression levels were measured via Western blot and real-time PCR. As a result, the water extract was found to have decrease the gene expression of SREBP-1c, PPAR, $C/EBP{\alpha}$, FAS, ACC in a dose-dependent manner. These indicate that the water extract inhibits pre-adipocyte differentiation and adipogenesis by blocking the SREBP-1c gene expression in 3T3-L1 cells. Therefore, P. tenuifolia can be used as an effective anti-obesity agent.

  • We investigated the anti-obesity effects of Ishige okamurae extract (IOE) on body weight, epididymal adipose tissue weight, plasma lipid levels, and leptin levels in high-fat diet (HFD)-induced obese mice. After inducing obesity by feeding 45% HFD for 4 weeks, C57BL/6J mice were randomly assigned to HFD or HFD containing 5% IOE, and then fed for 6 weeks. The body weight and epididymal adipose tissue weight were increased by HFD, but they were significantly less in animals fed HFD containing 5% IOE than in those fed HFD. Levels of plasma triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in animals fed HFD containing 5% IOE compared with the HFD group. The plasma leptin level was significantly lower in animals fed HFD containing 5% IOE. The diet containing 5% IOE did not show any adverse effects on liver and kidney functions. These results suggest that IOE has a potential as anti-obesity agent by reducing body weight and lowering the levels of obesity-related factors in plasma.

  • This study investigated anti-obesity and antioxidant effects of dietary non-fermented soybean crud residue (SCR) and fermented SCR by Monascus pilosus (FSCR) in high-fat induced-obese mice. SCR and FSCR were supplemented with high-fat diet at 2% (wt/wt) dose for 8 weeks. Both SCR and FSCR significantly lowered body weight, epididymal fat weight and weight gain rate compared to high-fat diet control (HC) group and FSCR group showed lowest weight gain rate. In addition, it was observed that serum and hepatic lipid profiles including triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol were significantly improved by supplementing SCR or FSCR. Furthermore, SCR and FSCR administration showed increase of glutathione content and decrease of hepatic lipid peroxide content, serum aminotransferase activity, and hepatic xanthine oxidase activity. On the other hand, activities of reactive oxygen species scavenging enzyme such as superoxide dismutase, glutathione S-transferase and glutathione peroxidase in two test groups were higher than those of HC. Lastly, in comparison with SCR, FSCR was more effective in restoring obesity-related biomarkers to normal level in high-diet induced obese mice. In conclusion, the present study indicates that FSCR could have not only anti-obese effects such as inhibition of abdominal fat accumulation, but also protective effects of cardiovascular disease such as atherosclerosis by decreasing serum and hepatic lipid contents. Furthermore, these results suggest that experimental diets in this study could alleviate hepatic damage caused by overproduction of reactive oxygen spices (ROS) due to obesity via inhibition of ROS generating activities and induction of ROS scavenging activities.

  • The anti-lipogenic effect of cereal samples on high sucrose diet (HSD)-induced non-alcoholic fatty liver disease (NAFLD) in mice was studied. We divided C57BL/6 mice into various groups based on 8 weeks of treatment with three types of cereal samples (HSD+WR, HSD diet containing 40% white rice; HSD+MCG, HSD diet containing 40% mixed cereal grain; HSD+AO-MCG, HSD diet containing 40% mixed antiobesity-cereal grain). After the experimental period, body weight changes, liver weights, serum lipid profiles, and hepatic fatty acid metabolism-related gene expression levels were determined. We found that HSD+WR, HSD+MCG, and HSD+AO-MCG treatments reduced body weight and liver weight, especially HSD+MCG and HSD+AO-MCG effectively reduced levels of serum triglycerides, total cholesterol, and low-density lipoprotein cholesterol. However, high density lipoprotein cholesterol levels increased compared to the control group. Furthermore, expression of hepatic lipogenic genes such as sterol regulatory element-binding protein-1c, acetyl-coenzyme A carboxylase, fatty acid synthase, stearoyl-coenzyme A desaturase-1, cluster of differentiation, and $PPAR-{\gamma}$ (peroxisome proliferator activated receptor ${\gamma}$) decreased, whereas expression of ${\beta}-oxidation$ genes such as $PPAR-{\alpha}$ and carnitine palmitoyl transferase-1 increased following HSD+MCG and HSD+AO-MCG treatment compared with levels in HSD+WR and control groups. These results suggest that the functional cereal samples, especially HSD+AO-MCG treatment, improved hepatic steatosis triggered by an HSD-induced imbalance in hepatic lipid metabolism.
