Obesity, the leading metabolic disease, is a prevalent health problem in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and even cancer. In this study, we investigated the effects of dip-sauce for meat containing Garcinia cambogia extract (GC) on the lipid accumulation and body weight reduction in rats fed high-fat diet for three months. Eighteen Sprague Dawley male rats of five-week-old were randomly assigned to one of three groups; normal chew diet (NCD) group, high-fat diet plus GC-noncontaining dip-sauce (HFD) group, and HFD plus GC-containing dip-sauce (HFD+GC) group. Co-administration of GC-containing dip-sauce (5 g/kg body weight/day) with HFD significantly attenuated cumulative body weight gain, compared with NCD or HFD groups. Both epididymal and perirenal fat pad weights in the HFD plus GC group were significantly lower than those of HFD or NCD groups. Administration of GC-containing dip-sauce also resulted in significant reduction in the serum levels of total cholesterol, total lipid, and triglyceride, compared with NCD or HFD groups. Thus, GC-containing dip-sauce confers beneficial effects to pathological states associated with metabolic disorder via its anti-obesity and lipid lowering properties.

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.

Objectives : Obesity is a chronic metabolic disease caused by disorder of energy balance and lipid metabolism. This study was conducted by histopathology and histomorphometry to investigate the anti-obesity effects of mixed water extract of Plantaginis Semen & Poria (CJB) on liver, epididymal fat pads and pancreas zymogen granules in obese rats induced with high fat diet. Method : Male Sprague-Dawley rats to be divided four groups were fed into four different treatments: normal (NOR) diet, high-fat (HF) diet, HF diet+CJB (100 mg/kg and 300 mg/kg, P.O.) for 8 weeks. The weekly body weights were measured in four experimental groups, respectively. Also histopathological and histomorphometrical changes of liver, epididymal fat pads and pancreas zymogen granules were observed in normal control and obese rats, respectively. Results : Adminstration of CJB significantly reduced body weights compared to those of HF group for experimental period. After 8 weeks, liver weights in the CJB groups were lower than those of HF group. In addition, HF diet related steatohepatitis, adipocyte hypertrophy, exocrine disturbances (decreases of pancreatic zymogen granules) were also dose-dependently inhibited by treatment of test material, CJB 100 and CJB 300 as compared with HF group, respectively. Conclusion : Based on the results, it is considered that CJB will be showed hepatoprotective and anti-obese effects, may be directly and/or indirectly mediated by pancreatic zymogen granules because they dose-dependently inhibited steatohepatitis, hypertrophy of adipocytes and decreases of pancreatic zymogen granules induced by HF diet supply, respectively.

In this study, we examined the effects of Rubus crataegifolius leaf on the inhibition of differentiation and adipogenesis of 3T3-L1 preadipocytes to confirm their potential for use as an anti-obesity functional material. Rubus crataegifolius leaves water extracted using hot water were then concentrated for use, with an extract yield of 4.76%. The result of measuring the rate of 3T3-L1 cell survival of Rubus crataegifolius leaf extract (RCLE) showed growth inhibition of 13% at a concentration of 1,000 ㎍/mL. Thus, in this study, experiments were performed using RCLE treatment concentrations up to 500 ㎍/mL. Production of triglycedie in 3T3-L1 cells showed a dose-dependent decrease, and the rate of reduction was 28.7, 40.8, and 51.6% at concentrations of 100, 300, and 500 ㎍/mL, respectively, compared to the control group. In addition, the results confirmed that suppression of lipogenesis was achieved by suppressing the expression of peroxisome proliferator-activated receptor γ (PPAR γ), CCAAT/enhancer-binding protein α (C/EBP α), sterol regulatory element-binding protein-1c (SREBP-1c), fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), and increasing the expression of p-activated protein kinase (p-AMPK). Based on these results, it is believed that Rubus crataegifolius leaf extract can be used in the effort to manage obesity by regulating factors related to adipocyte differentiation and adipogenesis.

This study was conducted to investigate the effects of ethanol extract from Lycii folium (L. folium) leaves on obesity index, serum lipids, homocysteine, leptin, ghrelin, and glucose in obese rats. Sprague-Dawley rats were administrated high-fat diets to induce obesity. Then, obese rats were divided into three diet groups: a basal-diet obese group (BO group), high-fat diet obese group (FO group), and high-fat diet plus L. folium extract obese group (FLEO group). Three groups were each fed experimental diet for 8 weeks. There were no significant differences in body weight and FER among the groups. However, obesity index such as Ro？hrer index, Lee index, and T.M. index of FLEO group was significantly decreased as compared to FO group. While serum triglyceride of BO group was significantly decreased as compared to FO group, there were no significant differences in serum lipids, homocysteine, leptin, ghrelin and glucose between FLEO group and FO group. In conclusion, these results indicated that ethanol extract from L. folium leaves might be beneficial with anti-obese effect by reduction of obesity indices in obese rats.

Low-grade pro-inflammatory state and leptin resistance are important underlying mechanisms that contribute to obesity-associated hypertension. We tested the hypothesis that Astragaloside IV (As IV), known to counteract obesity and hypertension, could prevent obesity-associated hypertension by inhibiting pro-inflammatory reaction and leptin resistance. High-fat diet (HFD) induced obese rats were randomly assigned to three groups: the HFD control group (HF con group), As IV group, and the As IV + ${\alpha}$-bungaratoxin (${\alpha}-BGT$) group (As IV+${\alpha}-BGT$ group). As IV ($20mg{\cdot}Kg^{-1}{\cdot}d^{-1}$) was administrated to rats for 6 weeks via daily oral gavage. Body weight and blood pressure were continuously measured, and NE levels in the plasma and renal cortex was evaluated to reflect the sympathetic activity. The expressions of leptin receptor (LepRb) mRNA, phosphorylated signal transducer and activator of transcription-3 (p-STAT3), phosphorylated phosphatidylinositol 3-kinase (p-PI3K), suppressor of cytokine signaling 3 (SOCS3) mRNA, and protein-tyrosine phosphatase 1B (PTP1B) mRNA, pro-opiomelanocortin (POMC) mRNA and neuropeptide Y (NPY) mRNA were measured by Western blot or qRT-PCR to evaluate the hypothalamic leptin sensitivity. Additionally, we measured the protein or mRNA levels of ${\alpha}7nAChR$, inhibitor of nuclear factor ${\kappa}B$ kinase subunit ${\beta}/nuclear$ factor ${\kappa}B$ ($IKK{\beta}/NF-KB$) and pro-inflammatory cytokines ($IL-1{\beta}$ and $TNF-{\alpha}$) in hypothalamus and adipose tissue to reflect the anti-inflammatory effects of As IV through upregulating expression of ${\alpha}7nAChR$. We found that As IV prevented body weight gain and adipose accumulation, and also improved metabolic disorders in HFD rats. Furthermore, As IV decreased BP and HR, as well as NE levels in blood and renal tissue. In the hypothalamus, As IV alleviated leptin resistance as evidenced by the increased p-STAT3, LepRb mRNA and POMC mRNA, and decreased p-PI3K, SOCS3 mRNA, and PTP1B mRNA. The effects of As IV on leptin sensitivity were related in part to the up-regulated ${\alpha}7nAchR$ and suppressed $IKK{\beta}/NF-KB$ signaling and pro-inflammatory cytokines in the hypothalamus and adipose tissue, since co-administration of ${\alpha}7nAChR$ selective antagonist ${\alpha}-BGT$ could weaken the improved effect of As IV on central leptin resistance. Our study suggested that As IV could efficiently prevent obesityassociated hypertension through inhibiting inflammatory reaction and improving leptin resistance; furthermore, these effects of As IV was partly related to the increased ${\alpha}7nAchR$ expression.

Purpose: This study was conducted in order to develop morning bread using powdered citrus peels and to examine the effect of its several biological activities for 12 weeks in overweight adults ($$BMI{\geq_-}23$$) living in dormitories of Chonbuk National University. Methods: Control bread was prepared using the same formula except for replacing the wheat flour with 3% citrus peel powder. Subjects were classified according to two groups: Intake group of 3% citrus peel powder fortified morning bread (n = 30) and general morning bread (n = 30). Results: The results of our study showed no significant effects of citrus peel powdered morning bread on anthropometric indices and biochemical characteristics among overweight adults. Despite the slight reduction in total-cholesterol, LDL-cholesterol, GOT, and GPT (p < 0.05), no significant differences in changes of these values were observed between the two groups. Conclusion: The short duration of our intervention might have resulted in the lack of any significant effect. Therefore, conduct of further studies with longer duration is warranted in order that the results from this study can be utilized as a basis for the development of food products with citrus peel powder.

In this study a natural composition containing oriental herbs, KSH28, for reducing obesity and metabolic syndrome was constructed and its efficacy was evaluated in animal and human. To investigate the anti-obesity effect of KSH28, animal study was conducted using high fat diet-induced obese mice. KSH28 significantly decreased body weight and adipose tissue in high fat diet-fed obese mice. The mean size of fat cells in adipose tissue was significantly reduced. Glucose and triglyceride levels were also significantly decreased. To elucidate its efficacy in human, a natural food containing KSH28 with grains, vegetables, vitamins, minerals and dietary fibers was constructed and 40 subjects (8 male and 32 female) were tested for the change of body composition, blood pressure and blood lipid profile. All subjects had 2 pack (309 each) of natural food per day for 4 weeks. Compared to the baseline value, body fat was significantly reduced, however, water, protein and mineral contents in the body were not changed, suggesting selective reduction of fat tissue. Blood pressure and serum lipid profile were significantly decreased to reduce risk for metabolic syndrome. Serum GPT, a liver function indicator, was not changed and no significant side effects were detected. Therefore, it was shown that the KSH28 is a safe and effective composition for reducing obesity and metabolic syndrome.
