This study was to examine the correlation between the brain function of adult suffering from obesity and the level of their obesity based on brainwave measurements. Based on the result of Body Composition Analysis (BCA) examination, population of 651 overweight pupils was chosen from June 2011 to December of 2012 in S city, I hospital. These patients were measured by timeseries linear analysis for their brain function and observed via brainwave activities. The results have been thus far; first, as their BMI (Body Mass Index) and level of obesity (body fat percentage) were higher, degree of mental stress and resistant to stress marked lower. These results prove that by managing the stress resistant ability and attention ability, self-controlling ability, one can expect a positive effect on finding a methods to ease the obese-related problems.

Black ginseng was made by steaming raw white ginseng nine times at $100^{\circ}C$ for 2 h and drying. We then performed pilot experiments using the nine black ginseng extracts for different steaming and drying times to determine their anti-obesity effects. Two ginseng extracts, steaming and drying five times (FSFD) and steaming and drying nine times (NSND), prepared in water or ethanol solution decreased lipid accumulation of 3T3-L1 cells. FSFD in water and ethanol extracts showed higher levels of ginsenosides, in particular, Rh1, Rg2, and Rb1 than NSND, and levels of the three ginsenosides were higher in ethanol extracts than in water extracts. Treatment with FSFD and/or NSND in ethanol extracts significantly regulated $PPAR{\gamma}$, C/$EBP{\alpha}$ and AMPK phosphorylation in 3T3-L1 cells. We verified doubling time of stem cells from both abdominal fat and subcutaneous fat after FSFD and NSND in ethanol and water extracts were added. Although addition of FSFD and NSFD in water extracts had no effects on proliferation, ethanol extracts with FSFD and NSND increased doubling time of stem cells in subcutaneous fat. FSFD and NSND in ethanol extracts more effectively reduced adipogenesis compared to those in water extracts. FSFD in ethanol extracts promoted secretion of anti-inflammatory cytokine such as IL-10 and depressed MCP-1 infiltration in 3T3-L1 preadipocytes co-cultured with RAW264.7 cells. We concluded that FSFD and NSND ethanol extracts may be developed as a functional food for its anti-obesity effect, but anti-inflammatory effect was shown in ethanol extracted FSFD rather than in NSND.

Cynanchi wilfordii Radix (CW) and Perilla sikokiana (PS) were extracted under different conditions to study their antioxidant, anti-diabetic, and anti-obesity activities. Their potentials as functional food ingredients were investigated. The highest total phenol contents were $15.74{\pm}0.69mg/g$ for CW100 [100% fermented ethanol (FE) extract from CW] and $39.37{\pm}3.46mg/g$ for PS50 (50% FE extract from PS). When extracts were processed at 1 mg/mL, DPPH radical scavenging activities were $79.79{\pm}0.79%$ and $82.69{\pm}1.07%$, respectively, at CW100 and PS50. ABTS radical scavenging activities were $80.20{\pm}2.86%$ and $75.00{\pm}1.78%$, respectively, at CW100 and PS50. However, ferric reducing antioxidant power activities at 1 mg/mL were higher than 80% for PS under all extraction conditions. The highest ${\alpha}$-amylase inhibitory activities were $51.56{\pm}0.56{\sim}59.2{\pm}1.13%$ at CW50 and $46.70{\pm}0.32{\sim}66.17{\pm}0.55%$ at PS0. Cell differentiation inhibitory effects in 3T3-L1 adipocytes were $29.49{\pm}2.98%$ at CW100 and $23.31{\pm}0.61%$ at PS50. The inhibitory effect of the CW100-PS50 mixture was $43.03{\pm}1.63%$, which was significantly higher than those of individual extracts.

Gnaphalium affine D. DON (GA) has been used as a vegetable as well as a folk medicine in East Asia. The antioxidant and anti-complementary activity of GA extract (GAE) has also been reported. However, little is known about its anti-inflammatory and anti-allergic effect and mechanism of action. In this study, we evaluated the inhibitory effects of GAE on the production of inflammatory mediators such as NO, $PGE_2$, TLR4, eotaxin-1 and histamine. Our results suggest that GAE inhibits the production of NO and $PGE_2$ by inhibiting transcriptional activation via the involvement of iNOS and COX-2. The LPS-induced expression of Toll-like receptor 4 (TLR4) was also attenuated. In addition, GAE inhibited A23187-induced histamine release from MC/9 mast cells. It also inhibited the production of eotaxin-1 induced by IL-4. Collectively, these results suggest that GAE may have considerable potential as a cosmetic ingredient with anti-inflammatory and anti-allergic properties.

Hermetia illucens (Black soldier fly) is attracting attention as an environmental purification insect because it can supply a wide range of by-products of the agricultural food industry. Also, it has a potential feed for fish, birds, and pets due to a short life cycle and excellent nutritional components. Several pharmacological effects, including antimicrobial, of H. illucens have been reported. However, no study has focused on antiobesity effects of ethanol extract of H. illucens. In this study, we aimed to assess the anti-obesity effects of ethanol extract of H. illucens larvae (HIE) through inhibition of differentiation of 3T3-L1 preadipocytes into adipocytes. The amount of lipid accumulated in adipocytes was measured by oil red-O staining, and the inhibitory effect on adipogenesis was confirmed. The expression levels of factors related to adipocyte differentiation and fat synthesis were determined using Western blot analysis. Lipid droplet formation in adipocytes was remarkably inhibited by HIE. In addition, treatment with 400 ㎍/ml of HIE significantly reduced the expression levels of peroxisome proliferator-activated receptor γ and CCAAT/enhancer-binding protein α-transcription factors involved in adipocyte differentiation. Therefore, the results of this study indicate that HIE is a potential anti-obesity agent because it inhibits adipocyte differentiation.

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.

Objective This study investigated the effects of Jeoreongchajeonja-tang in a high-fat diet-induced obesity mouse model. Methods The study examined 9-week-old male mice (C57bl/6J) divided into four groups: the normal(C57bl/6J-Nr), control (high-fat diet only; HFD-CTL), positive-control (high-fat diet with Garcinia cambogia), and experimental (high-fat diet with Jeoreongchajeonja-tang; HFD-JCT) groups. After 7 weeks, the body weight, food efficiency ratio, organ weight, and visceral fat weight of the mice were measured. Blood serum tests, mRNA, liver histopathology, and epididymis adipocytes were also examined. Results Compared with the Control(HFD-CTL) group, the Experimental(HFD-JCT) group given Jeoreongchajeonja-tang showed significant reductions in absolute body weight and food efficiency ratio. The serum alanine aminotransferase, total-cholesterol, triglyceride, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, insulin-like growth factor-1, and leptin levels were significantly lower in the experimental group than in the control group. The serum adiponectin levels were significantly higher in the experimental group than in the control group. Compared with the control group, the experimental group showed significant reductions in absolute abdominal subcutaneous fat, epididymal adipose tissue, kidney adipose tissue, intestine adipose tissue, and liver, kidney and spleen adipose tissue weights. The C/EBP-${\beta}$, leptin, and SREBP1c/ADD1 mRNA expression were significantly lower in the experimental group than in the control group, while the UCP-2 and adiponectin mRNA expression were significantly higher. Compared with the control group, the experimental group showed a significant reduction in the absolute adipocyte area in the liver and epididymal adipose tissue. Conclusion Jeoreongchajeonja-tang has an anti-obesity effect. Additional clinical studies are expected.

The aims of this investigation was to examine the anti-obesity effects of oral administration with Mulberry leaves extraction in the high-fat diet induced obesity rats. We investigated the anti-obesity effects of the extract from Mulberry leaves on the progress of high fat diet for 8 weeks. Experimental rats were divided into 5 different experimental groups including an normal group (normal dieat; n=10), control group (high fat diet; n=10), I (Mulberry leaves extraction 100 mg/kg oral administration induced obesity; n=10), II (Mulberry leaves extraction 300 mg/kg oral administration; n=10), and III (Mulberry leaves extraction 500 mg/kg oral administration; n=10). It is to analysis changes in body weight, epididymal fat weight, blood lipid profiles, and fat histological findings. Body weights were significantly increase in control group than normal groups(p<0.05). The level of total cholesterol, LDL-C and TG were significantly lower in experimental groups than control group (p<0.05). In histopathologic finding of fat-tissue around testicle experimental group I and II were more decreased than high fat diet-induced control group in fat cell size. These results suggested that the Mulberry leaves extraction oral administration made the increase of anti-obesity effect in high-fat diet induced obesity rats.
