To compare the medical efficacy of original Socheongyong-tang with fermented Socheongyong-tang, we've studied the two medicines according to the search for optimal bacteria and optimal conditions, component analysis, assessment of medical efficacy and toxicity, and have the result below. The results were obtained as follows: Considering bacterial growth, $CO_2$ gas emission and pH, we examined that using 3 kinds of bacteria(S. cerevisiae KCTC 7913, L. casei KCTC 3109, L. brevis KCTC 3102) is desirable. There is no main difference in optimum conditions between incubator and shaking incubator. And it is considered that ideal fermentation time is 2 days after vaccination. As the result of componential analysis of before and after fermentation, there's a noticeable decrease of total sugar and protein. But there's no alterations in total phenolics compounds and in total flavonoid compounds that influence on medical effect. The result was interpreted that it can promote the assimilation of herbal decoction after fermentation. As the result of medical efficacy assessment, we can check out that there is more anti-oxidating effects in fermented Socheongyong-tang, whereas anti-inflammatory effects and obesity-preventing effects were favorable in original Socheongyong-tang. And there is no main difference of whitening and COX-2 removing effects between before and after the fermentation. As a result of assessing weight change, hepatotoxicity and nephrotoxicity, we can not notice any unusual difference between before and after the fermentation. According to the results above, it is considered that we checked out the optimal bacteria and optimal conditions, advantages and disadvantages of the medical efficacy of original Socheongyong-tang and fermented Socheongyong-tang. And we suggest that there will have to be a following in-depth and systematic research on this subject in the future.

Objectives: The aim of this study is to investigate anti-imflammatory and protective effect for intestinal epithelial cells with Atractylodes macrocephae (AM), a traditional Korean Herbal medicine and fermented Atractylodes macrocephae (FAM) with Lactobacillus plantarum. Methods: HCT-116 and Raw 264.7 cells were used in this study. Using NO assay, we measured lipopolysaccharide (LPS)-induced anti-inflammatory effect. We measured permeability of intestinal epithelial cells with transepithelial electrical resistance and horseradish peroxide flux assay. Water soluble tetrazolium salt assay was used to see cell proliferation. All the results were presented in mean and standard deviation. We used Student's t-test for analyzing significance of results. Results: In Raw 264.7 cells NO production decreased 22.4% with pre-treatment of AM and FAM, especially with FAM in high concentration. In HCT-116 cells LPS-induced intestinal permeability had a protective effect with both AM and FAM, which was also tend to be proportional to the concentration. Cell viability increased up to 135.52% after treatment of high concentration of FAM in HCT-116, while there was no significant change in Raw 264.7 cells with herb treatments. Conclusions: These results show evidence that AM, especially fermented ones, significantly reduced intestinal membrane permeability. They also had a protective effect as well as an anti-inflammation effect for HCT-116 and Raw 264.7 cells. This suggest that FAM may be a therapeutic agent for Leaky gut syndrome by reducing intestinal permeability.

In this study, soybean pods of 45 soybean landraces (or varieties) were classified as yellow (19 samples), black (23 samples), or black in green (3 samples) based on soybean seed coat color. Total polyphenol and flavonoid contents were measured, and antioxidant, anti-inflammatory, anti-obesity, and estrogen-like activities were assessed. Total polyphenol and flavonoid content ranges were 24.13-108.03 mg GAE/g and 3.31-72.02 mg CE/g, respectively, and were highest in the black group followed by the yellow group and were least in the black in green group, while ABTS and DPPH activities followed the order black in green > black > yellow. Estrogen-like and estrogen receptor-α activity ranges were 29.06-35.58 pg/mL and 7.05-10.13 pg/mL and were followed the order yellow > black > black in green and black in green > yellow > black, respectively. Nitric oxide (NO) inhibitory and UCP-1 activities followed the same order as estrogen receptor-α activities. Our findings suggest that soybean pods are excellent sources of antioxidants and high-quality functional materials.

Codium fragile (Suringar) Hariot, a green alga of the Codiales family, has been reported to have several bioactive properties, including antioxidant and anti-inflammatory properties. However, its antiobesity and whitening effects and their underlying mechanisms are unclear. This study aimed to evaluate the antiobesity and melanogenesis inhibitory effects of C. fragile using methanol extracts of C. fragile (MECF). The results of this study revealed that MECF inhibited the accumulation of lipid droplets and triacylglycerol in differentiated 3T3-L1 adipocytes, which was associated with the inhibition of the expression of adipogenesis-related transcription factors, such as peroxisome proliferator-activated receptor γ, CCAAT/enhancer-binding protein-α (C/EBPα), and C/EBPβ, which function as the key regulators of adipogenesis. Also, MECF reduced tyrosinase activity and melanin content in B16F10 cells as well as the expression of tyrosinase, tyrosinase-related protein-1 (TRP-1), TRP-2, and microphthalmia-related transcription factor in the presence of α-melanocyte-stimulating hormone. Taken together, our findings suggest that the extract of C. fragile could be considered a promising functional ingredient for the prevention and treatment of obesity and skin pigmentation in the food and cosmetic industry.

Purpose: This study aimed to identify gender differences associated with weight related teasing by parents, and development of anti-fat attitudes among Korean children aged 5 to 7 years. Methods: This study used a descriptive cross-sectional design. Questionnaire interviews were conducted by enrolling 222 healthy children having normal development and living with their parents in South Korea. Results: Results showed gender and parental weight-related teasing was significantly associated with anti-fat attitudes among children. Significance of the association between parental weight-related teasing and anti-fat attitudes among kindergarten children differed according to the child's gender. Among girls, the higher level of parental weight-related teasing was associated with greater anti-fat attitude. However, parental weight-related teasing was not associated with increased anti-fat attitude among boys. Conclusion: Considering our study results, we recommend developing programs aimed towards decreasing teasing in the family environment, such as changing the gender-specific weight norms to prevent anti-fat attitudes in Korean girls.

We investigated the anti-obesity and anti-hyperlipidemic effects of extracts of two roasted coffee beans (Vietnam robusta and Ethiopia mocha sidamo G2) and fermented coffee beans with Monascus rubber mycelium (MR) by solid-state culture. C57B/L6 mice were divided into seven groups: normal diet (ND) group, high fat diet (HFD) group, and HFD groups with hot water extracts from Vietnam robusta coffee beans (HFD-VR), MR-fermented Vietnam robusta coffee beans (HFD-VR-MR), MR-fermented Vietnam robusta coffee beans with 10% brown rice (HFD-VR-MR-BR10), Ethiopia mocha sidamo G2 coffee beans (HFD-ES), and MR-fermented Ethiopia mocha sidamo G2 coffee beans (HFD-ES-MR). After 6 weeks, body weight gain and food efficiency ratio were higher in the HFD group, but significantly reduced in the coffee extracts-fed groups. The HFD-ES-MR group showed greater body weight reduction than the HFD-ES group. The serum triglyceride, total cholesterol, and LDL-cholesterol levels as well as the atherogenic index and cardiac risk factor all tended to decrease in groups fed Vietnam robusta coffee extracts compared to the HFD group. These results suggest that Vietnam robusta and Ethiopia mocha sidamo G2 may be used to make functional coffee beverages with anti-obesity and anti-hyperlipidemic activities.

The herb of Allium victorialis var. platyphyllum (Liliaceae) has been used as an edible wild herb and to treat heart failure and gastritis. We have already reported antihyperlipidemic anti-tumor effects of this plant. To enlarge the commercial availability of this food, it was investigated whether the extracts of A. victorialis var.platyphyllum reduce hyperlipidemia and obesity or not. The plants tested in this experiment were collected from two eco-types of IS. Ullung and Mt. Odae cultivated at Pyongchang. Extracts were prepared by extracting the fresh leaves and those dried at $36^{\circ}C$ and $90^{\circ}C$, respectively. Pretreatment with the ethanolic extracts for two weeks (p.o.) reduced serum triglyceride-, total cholesterol- and LDL-cholesterol contents in rats induced by Triton WR-1339, respectively. Furthermore, oral administration of the extracts also inhibited the hyperlipidemia induced with oral diet of 30% corn oil. In the other attempt to find to alleviate the obesity, the model rats with obesity were induced by the high fat-diet for six weeks. Post-treatment with the extracts for two weeks significantly reduced the hyperlipidemia. Retroperitoneal-, epidymal- and total abdominal fat pad weights were considerably reduced at 100 mg/kg oral administration of the extracts. Increased feces lipid contents were also found in the rat treated with the extracts. The extract of Mt. Odae eco-type showed more potent activity than that of Is. Ullung one. These results suggest that use of the fresh leaves may lead to the higher activity in treatment of hyperlipidemia and obesity than of the dried one.

Objectives This study was designed to evaluate the efficacy of Seungyangjeseup-tang on obesity by using 3T3-L1 cells and high fat diet mice. Methods In vitro, Seungyangjeseup-tang extract (SYJST) (10, 50, 100, 200, 400, $800{\mu}g/mL$) ware added in 3T3-L1 cells. SYJST cytotoxicity was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assasy. Adipocyte differentiation was measured by Oil Red-O staining. In vivo, the experimental animals were divided into five groups: normal diet-fed normal group (N), high-fat diet (HFD)-fed control group (Con), HFD+SYJST 100 mg/kg group (SY100), HFD+SYJST 200 mg/kg group (SY200), and HFD+olistat 60 mg/kg as a positive drug control group (Orli). Markers of obesity, such as body weight, liver weight, food intake, serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), liver tissue TC, TG and fecal TC, TG were measured. Results In vitro, cytotoxicity was not significant compared with the control group. 3T3-L1 cell's differentiation was significantly decreased in Oil Red-O staining. In vivo, compared with controls, mice treated with SYJST demonstrate lower body and liver weight, and reduced food intake. In addition, SYJST increased TC, TG in the serum but not significance. And SYJST showed decreasing tendency TC, TG in the liver tissue. Furthermore, SYJST increased TC, TG in the facal but not significance. Conclusions Based on the results above, Seungyangjeseup-tang may reduce adipocyte differentiation, body fat, food intake, liver weight in obesity. This suggests that Seungyangjeseup-tang may be clinically useful in obesity treatment.

BACKGROUND/OBJECTIVES: Obesity-induced steatohepatitis accompanied by activated hepatic macrophages/Kupffer cells facilitates the progression of hepatic fibrinogenesis and exacerbates metabolic derangements such as insulin resistance. Heme oxyganase-1 (HO-1) modulates tissue macrophage phenotypes and thus is implicated in protection against inflammatory diseases. Here, we show that the flavonoid quercetin reduces obesity-induced hepatic inflammation by inducing HO-1, which promotes hepatic macrophage polarization in favor of the M2 phenotype. MATERIALS/METHODS: Male C57BL/6 mice were fed a regular diet (RD), high-fat diet (HFD), or HFD supplemented with quercetin (HF+Que, 0.5g/kg diet) for nine weeks. Inflammatory cytokines and macrophage markers were measured by ELISA and RT-PCR, respectively. HO-1 protein was measured by Western blotting. RESULTS: Quercetin supplementation decreased levels of inflammatory cytokines ($TNF{\alpha}$, IL-6) and increased that of the anti-inflammatory cytokine (IL-10) in the livers of HFD-fed mice. This was accompanied by upregulation of M2 macrophage marker genes (Arg-1, Mrc1) and downregulation of M1 macrophage marker genes ($TNF{\alpha}$, NOS2). In co-cultures of lipid-laden hepatocytes and macrophages, treatment with quercetin induced HO-1 in the macrophages, markedly suppressed expression of M1 macrophage marker genes, and reduced release of MCP-1. Moreover, these effects of quercetin were blunted by an HO-1 inhibitor and deficiency of nuclear factor E2-related factor 2 (Nrf2) in macrophages. CONCLUSIONS: Quercetin reduces obesity-induced hepatic inflammation by promoting macrophage phenotype switching. The beneficial effect of quercetin is associated with Nrf2-mediated HO-1 induction. Quercetin may be a useful dietary factor for protecting against obesity-induced steatohepatitis.

BACKGROUND/OBJECTIVES: The steamed ginger has been shown to have antioxidative effects and a protective effect against obesity. In the present study, we investigated the effects of ethanolic extract of steamed ginger (SGE) on adipogenesis in 3T3-L1 preadipocytes and diet-induced obesity (DIO) mouse model. MATERIALS/METHODS: The protective effects of SGE on adipogenesis were examined in 3T3-L1 adipocytes by measuring lipid accumulations and genes involved in adipogenesis. Male C57BL/6J mice were fed a normal diet (ND, 10% fat w/w), a high-fat diet (HFD, 60% fat w/w), and HFD supplemented with either 40 mg/kg or 80 mg/kg of SGE for 12 weeks. Serum chemistry was measured, and the expression of genes involved in lipid metabolism was determined in the adipose tissue. Histological analysis and micro-computed tomography were performed to identify lipid accumulations in epididymal fat pads. RESULTS: In 3T3-L1 cells, SGE significantly decreased lipid accumulation, with concomitant decreases in the expression of adipogenesis-related genes. SGE significantly attenuated the increase in body, liver, and epididymal adipose tissue weights by HFD. Serum total cholesterol and triglyceride levels were significantly lower in SGE fed groups compared to HFD. In adipose tissue, SGE significantly decreased adipocyte size than that of HFD and altered adipogenesis-related genes. CONCLUSIONS: In conclusion, steamed ginger exerted anti-obesity effects by regulating genes involved in adipogenesis and lipogenesis in 3T3-L1 cell and epididymal adipose tissue of DIO mice.
