Objectives: This study was performed to investigate anti-obesity effects of Zingiberis Rhizoma on ovariectomized rats in order to determine the possibility of the clinical use in preventing and treating post-menopausal obesity. Methods: To investigate how menopause affects obesity in woman, rats were treated with Zingiberis Rhizoma extracts. We measured various biomarkers including GOT,GPT, leptin, ghrelin, adiponectin, $PPAR-{\gamma}$ mRNA, total cholesterol, triglyceride, HDL-cholesterol, liver weight, estradiol, uterine weight, and calcitonin, which are linked with obesity and menopause. Results: There was a significant decrease in group which was given Zingiberis Rhizoma extracts 100 mg/kg and lipid level found in blood(total cholesterol, triglyceride). Fat accumulation of liver cells was repressed, liver function was improved and leptin and adipomectin levels were significantly normalized. In addition, expression of $PPAR-{\gamma}$ was significantly increased. Conclusions: The results indicated that Zingiberis Rhizoma extracts have anti-obesity effects on ovariectomized rats through improving liver function and lipid metabolic function.

Recently the global epidemic problem of obesity has stimulated intense interest in the study of physiological mechanisms using animal models as a way to gain crucial data required for translation to human studies. Panax ginseng has been reported to have anti-obesity or antidiabetic effects in many animal studies; however, there have been few studies investigating human obesity. Herein, we will assess and examine the evidence supporting the anti-obesity effect of Panax ginseng in animal models with respect to anthropometric and metabolic outcomes. We will include controlled, comparative studies assessing the effect of Panax ginseng in preclinical studies of obesity. Panax ginseng will be administered during or following the induction of experimental obesity. The primary outcome measure will be anthropometric assessment and the secondary outcome measures will include adipose tissue weight, total amount of food consumed and metabolic parameters. We will search MEDLINE, Embase, PubMed, Web of Science, and Scopus without language, publication date, or other restrictions. Ethical approval will not be necessary as the data collected in this study will not be individual patient data, consequently there will be no concerns about violations of privacy. After finishing the whole procedure, the results will be disseminated by publication in a peer-reviewed journal or presented at a relevant conference. This protocol has been registered on the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADES) website (http://www.camarades.info).

Sasa borealis has long been used in folk remedies and traditional Korean medicine for analgesic, sedative and anticarcinogenic purposes. To excavate novel natural compounds for treating obesity, we separated leaf and stem and fractionated. We screened phenolic contents, anti-oxidative and anti-inflammatory properties with the fractions. Dichloromethane (DCM) and ethyl acetate (EA) fraction from both leaf and stem exhibited high anti-oxidative properties demonstrated by DPPH, ABTS assay in accordance with their phenolic contents. In addition, DCM and EA fraction from leaf inhibited nitric oxide (NO) production as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in Raw 264.7 cell. Finally, DCM and EA fraction from both leaf and stem significantly inhibited 3T3-L1 preadipocyte differentiation and decreased intracellular lipid level. These results suggest that DCM and EA fraction from Sasa borealis may contain therapeutic agent for obesity by attenuating inflammation and oxidative stress.

Objectives : This comparative study was to investigate on anti-obesity effects of Ephedrae Herba and Cyperi rhizoma in high fat diet(HFD) fed mice. Methods : Male C57BL/6J mice were fed a normal diet(normal group, N), high fat 45 cal% diet[HFD, control group, C), HFD with Ephedrae Herba(EH group) and Cyperi rhizoma(CR group) extracts fed for 5 weeks. We were observed as follows : changes of body weight, amount of diet intake, weight of total visceral fats, levels of obesity-related hormones and blood lipids. Results : The change of body weight after EH and CR oral administration significantly more decreased in EH group than that of control group. The FFR(Food Efficiency Ratio) was decreased in EH group, but more increased in CR group than that of control group. The weight of periepididymal and perirenal fats were significantly decreased in EH and CR groups compared to the control group. The levels of serum leptin and insulin were significantly decreased in EH group, and the level of serum adiponectin was increased in EH group compared to control group. The levels of serum triglyceride and total cholesterol were significantly decreased in EH and CR groups, and HDL-cholesterol levels was significantly increased in EH group compared to control group. Conversely in CR group, its values showed the opposite effect. The staining density of lipid droplets within the hepatocytes was widely distributed in CR and control groups, but in EH group, its density was weakly stained. Conclusions : These experimental results suggest that Ephedrae Herba shows conspicuous anti-obesity effect, and Cyperi rhizoma shows weak anti-obesity effect.

Background: This study investigated the anti-obesity effect of the flavonoid rich fraction (FRF) and its constituent, rutin obtained from the leaf of Morus alba L., on the lipid accumulation mechanism in 3T3-L1 adipocyte and C57BL/6 mouse models. Methods and Results: In Oil Red O staining, FRF (1,000 ㎍/㎖) treatments showed inhibition rate of 35.39% in lipid accumulation compared to that in the control. AdipoRedTM assay indicated that the triglyceride content in 3T3-L1 adipocytes treated with FRF (1,000 ㎍/㎖) was reduced to 23.22%, and free glycerol content was increased to 106.04% that of the control. FRF and its major constituent, rutin affected mRNA gene expression. Rutin contributed to the inhibition of Sterol regulatory element binding protein-1c (SREBP-1c) gene expression, and inhibited the transcription factors SREBP-1c, peroxisome proliferator-activated receptor gamma (PPAR-γ), CCAAT/enhancer binding protein α (C/EBPα), fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC). In addition, the effect of FRF administration on obesity development in C57BL/6 mice fed high-fat diet (HFD) was investigated. FRF suppressed weight gain, and reduced liver triglyceride and leptin secretion. FRF exerted potential anti-inflammatory effects by improving insulin resistance and adiponectin levels, and could thus be used to help counteract obesity. The mRNA expressions of PPAR-γ, FAS, ACC, and CPT-1 were determined in liver tissue. Quantitative real-time PCR analysis was also performed to evaluate the expression of IL-1β, IL-6, and TNF-α in epididymal adipose tissue. Compared to the control group, mice fed the HFD showed the up-regulation in PPAR-γ, FAS, IL-6, and TNF-α genes, and down-regulation in CPT1 gene expression. FRF treatement markedly reduced the expression of PPAR-γ, FAS, IL-6, and TNF-α compared to those in HFD control, whereas increased the expression level of CPT1. Conclusions: These results suggest that the FRF and its major active constituent, rutin, can be used as effective anti-obesity agents.

Obesity increases the risk of many adult diseases, such as atherosclerosis, diabetes, hypertension, ischemic heart disease and breast cancer. Inhibition of adipogenesis is an effective way in the anti-obesity management. Because of main components of Saururus chinensis is flavonoid, it has been showed some improvement by its antioxidant effects on the atherosclerosis, heart disease and diabetic hyperlipidemia. But mechanism of anti-obesity effect of S. chinensis is not clear. We investigated the effects of ethanol extracts of S. chinensis on adipogenesis in the 3T3-L1 pre-adipocyte. The 3T3-L1 cell line is commonly used to study adipogenesis in vitro. In this study, ethanol extracts of S. chinensis significantly decrease the lipid accumulation in the 3T3-L1 cells proved by measuring triglyceride contents and Oil red O staining. The proposed mechanism of inhibition of adipogenesis in the 3T3-L1 cells with ethanol extracts of S. chinensis is down-regulation of transcriptional factors and adipocyte-specific genes such CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) and Peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$) in concentration dependent pattern. These results suggest that ethanol extracts of S. chinensis inhibits adipognesis in the 3T3-L1 cells and can be used as a safe and efficient natural substance to manage anti-obesity.

In this study, we investigated in vitro anti-obesity activity of Parthenocissus tricuspidata (Siebold & Zucc.) Planch stem (PTS) in mouse adipocytes 3T3-L1 cells. PTS inhibited lipid accumulation and reduced the expression level of the proteins such as C/EBPα, PPARγ and FABP4 associated with adipogenesis in 3T3-L1 cells. In addition, PTS increased lipolysis-related protein expression such as p-AMPK, ATGL and p-HSL, and reduced perilipin-1 in 3T3-L1 cells. Taken together, PTS may have anti-obesity activity through inhibiting adipogenesis and inducing lipid lipolysis in adipocytes. Based on these results, PTS is expected to be used as a potential functional agent for anti-obesity.

In vitro anti-obesity effects of anti-cancer (AC) functional kimchi in differentiated 3T3-L1 adipocytes were studied. We constructed three experimental groups: Control, standardized kimchi (SK), and AC functional kimchi (A-FK) that included active ingredients and Lactobacillus plantarum. Kimchi extracts did not show any cytotoxicity in pre-adipocytes in the concentration range of 1 - 5 mg/mL. A-FK significantly reduced fat droplet formation and absorbance in differentiated 3T3-L1 adipocytes, as shown by Oil red O staining, compared to Control and SK (P < 0.05). SK and A-FK reduced adipo-/lipogenesis related genes such as $C/EBP{\alpha}$, SREBP-1, LPL, and $LXR{\alpha}$ compared to Control (P < 0.05). Especially, A-FK more greatly reduced SREBP-1 and LPL compared to SK (P < 0.05). A-FK up-regulated the ${\beta}$-oxidation related gene CPT-1c and down-regulated the pro-inflammatory cytokine IL-6 compared to Control (P < 0.05). Based on the results, A-FK exhibited anti-obesity effects by inhibiting fat droplet formation and adipo-/lipogenesis related genes by regulating the ${\beta}$-oxidation related gene CPT-1c and pro-inflammatory cytokine IL-6. In previous studies, A-FK kimchi already exhibited a strong anti-cancer effect. These results indicate that A-FK increased anti-obesity activity in this model system due to its functional ingredients and anti-cancer functionality.

Obesity has become one of the main public health problems. Saussurea lappa (Asteraceae), syn Aucklandia lappa and Saussurea costus, is a well-known herbal medicine that has been used for treating various ailments, such as inflammatory and gastrointestinal diseases. The present study examined the anti-obesity effect of S. lappa extract (SLE) in 3T3-L1 adipocytes and high fat diet (HFD)-induced obese mouse model. SLE significantly inhibited the differentiation from preadipocytes to adipocytes of cultured 3T3-L1 in dose-dependent manner. In addition, SLE significantly decreased the body weight gain and the food efficiency ratio of mice fed HFD during 9 weeks. Further study must be performed for the pharmacological mechanism and safety of SLE as well as the identification of active compound in SLE. Our results revealed that S. lappa suppresses the adipogenesis in cultured cells and the obesity in rodent models. Therefore, S. lappa may be useful toward the development of new potent anti-obesity drugs.

Obesity is a major risk factor for various metabolic diseases such as cardiovascular disease, hypertension, and type 2 diabetes mellitus. In this study, we prepared ethanol extracts from Agastache rugosa (ARE), Chrysanthemum zawadskii (CZE), Mentha arvensis (MAE), Perilla frutescens (PFE), Leonurus sibiricus (LSE), Gardenia jasminoides (GJE), and Lycopus coreanus (LCE). The anti-oxidant and anti-adipogenic effects were evaluated. The $IC_{50}$ values for ascorbic acid and LCE against 2,2-diphenyl-1-picrylhydrazyl radicals were $246.2{\mu}g/mL$ and $166.2{\mu}g/mL$, respectively, followed by ARE ($186.6{\mu}g/mL$), CZE ($198.6{\mu}g/mL$), MAE ($337.1{\mu}g/mL$), PFE ($415.3{\mu}g/mL$), LSE ($548.2{\mu}g/mL$), and GJE ($626.3{\mu}g/mL$). In non-toxic concentration ranges, CZE had a strong inhibitory effect against 3T3-L1 adipogenes (84.5%) than those of the other extracts. Furthermore, the anti-adipogenic effect of CZE is largely limited in the early stage of adipogenesis, and we revealed that the inhibitory role of CZE in adipogenesis is required for the activation of Wnt signaling. Our results provide scientific evidence that the anti-adipogenic effect of CZE can be applied as an ingredient for the development of functional foods and nutri-cosmetics for obesity prevention.
