Boesenbergia pandurata (Roxb.) Schltr. has been reported to possess anti-oxidative and anti-inflammatory properties. The aim of this study was to investigate the effect of Boesenbergia pandurata extract (BPE) in a high-fat diet (HFD)-induced obese mice model. C57BL/6J mice were fed with either the high-fat diet or a 0.5% BPE-supplemented HFD for 8 weeks. The BPE-containing HFD significantly reduced body weight gain and the accumulation of visceral fat mass in mice model without altering the amount of food intake. Moreover, mice fed with BPE-containing HFD had lower concentrations of lipids in their blood, lower hepatic lipid accumulation, and lower serum leptin levels compared with the HFD-fed mice. RT-PCR analysis showed that the expression levels of peroxisome proliferators-activated receptor ${\gamma}2$ ($PPAR{\gamma}2$) and CCAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) genes in the epididymal fat tissue of mice fed the BPE-containing HFD increased 1.16- and 1.30-fold, respectively, compared to mice fed HFD only. In conclusion, BPE attenuated visceral fat accumulation and improved dyslipidemia in a mice model with HFD-induced obesity.

Purpose: The aim of this study was to analyze the association between sodium excretion and obesity for healthy adults in the Gwangju area. Methods: The participants included 80 healthy adults aged 19 to 69 years in Gwangju. The dietary intake and sodium excretion were obtained using the 24-hour recall method and 24 hour urine collection. The participants were classified into two groups according to the amount of urinary sodium excretion: (${\leq}141.75mmol/dL$, > 141.75 mmol/dL). Results: After adjusting for sex, age, smoking history, and income, the high excretion of sodium group was significantly higher for weight, body mass index, body fat mass, percent body fat, visceral fat area (VFA), waist circumference, hip circumference, and WHR. The energy and nutrients intake were significant after adjusting for sex, age, smoking history, and income. The LSE group had a significantly higher fat intake and Na/K intake ratio. The HSE group had significantly higher fiber intake, and K intake. As the amount of urinary sodium excretion increased, the risk of obesity before correction was 3.57 (95% CI: 1.13-11.25) times greater, and the risk of obesity of T3 increased significantly by 3.33 times (95% CI: 1.05-10.59). After correcting for sex and age, the obesity risk of T2 increased significantly by 4.23 times (95% CI: 1.11-16.06), and after correcting for sex, age, smoking history, and income, the obesity risk of T2 increased significantly by 6.81 times (95% CI: 1.44-32.19) the risk of obesity. Conclusions: An association exists between sodium excretion and obesity in Korean adults. In this study, the high excretion of sodium group was obese and the risk of obesity was higher than the low excretion of sodium group.

Probiotic supplements have promising therapeutic effects on chronic diseases. In this study, we demonstrated the anti-obesity effects of two potential probiotics, Bifidobacterium bifidum DS0908 (DS0908) and Bifidobacterium longum DS0950 (DS0950). Treatment with DS0908 and DS0950 postbiotics significantly induced the expression of the brown adipocyte-specific markers UCP1, PPARγ, PGC1α, PRDM16 and beige adipocyte-specific markers CD137, FGF21, P2RX5, and COX2 in C3H10T1/2 mesenchymal stem cells (MSCs). In mice with high-fat diet (HFD)-induced obesity, both potential probiotics and postbiotics noticeably reduced body weight and epididymal fat accumulation without affecting food intake. DS0908 and DS0950 also improved insulin sensitivity and glucose use in mice with HFD-induced obesity. In addition, DS0908 and DS0950 improved the plasma lipid profile, proved by reduced triglyceride, low-density lipoprotein, and cholesterol levels. Furthermore, DS0908 and DS0950 improved mitochondrial respiratory function, confirmed by the high expression of oxidative phosphorylation proteins, during thermogenesis induction in the visceral and epididymal fat in mice with HFD-induced obesity. Notably, the physiological and metabolic changes were more significant after treatment with potential probiotic culture-supernatants than those with the bacterial pellet. Finally, gene knockdown and co-treatment with inhibitor-mediated mechanistic analyses showed that both DS0908 and DS0950 exerted anti-obesity-related effects via the PKA/p38 MAPK signaling activation in C3H10T1/2 MSCs. Our observations suggest that DS0908 and DS0950 could potentially alleviate obesity as dietary supplements.

Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

Obesity is a physical condition that results from excessive storage of fat in the body. The present study examined the anti-obesity effects of the selected natural medicine, Galla rhois extract (GRE) and solvent fractions on 3T3-L1 preadipocytes and in vivo studies. Here, we show that EtOAc fraction of Galla rhois inhibits the differentiation of the 3T3-L1 preadipocytes induced by differentiated medium in a dose-dependent manner. To investigate the effect of the GRE-EtOAc fraction on obesity in high fat diet-fed C57BL/6 mice, which included a normal diet (ND), high-fat diet (HFD) and HFD+GRE concentration-dependent, were fed to the mice for 6 weeks. The GRE-EtOAc fraction was inhibited the highest adipocyte differentiation in vitro, the GRE supplement significantly decreased body weight and visceral fat mass compared to the HFD group. The total cholesterol and triglyceride levels in the plasma were significantly decreased by GRE supplementation compared with those of the HFD group. Also, we aimed to determine the differentiation inhibition and the modulation of differentiation genes brought about by the Galla rhois in adipocyte. A cDNA microarray-based method was introduced for the high contents screening (HCS) of gene expressions. This technology has revolutionized gene expression studies by providing the means to measure mRNA levels in thousands of genes simultaneously in simple and complex biological samples. 13 genes were founded to be affected in their expression levels by more than 5-fold up-regulation after 4 days treatment with the EtOAc fraction from Galla rhois. Otherwise, 21 genes were founded to be affected in their expression levels by more than 5-fold down-regulation treated with the EtOAc fraction. Therefore, Galla rhois extract may be considered for use in a therapeutic agent to control obesity.

Objectives This study was conducted to experimentally evaluate the effects of Younggyechulgam-tang-ga Hwanggi(YGT) on obesity in mice induced by high fat diet. Methods The experiment was conducted with 4-week-old male mice divided into 5 groups. They were a normal diet group(Nor), a high fat diet group(Veh), a positive drug control group-orlistat 40 mg/kg(Oris), a 1.08 g/kg group(YGTL), and a 2.16 g/kg group(YGTH), and were tested for five weeks. Changes in antioxidant activity, body weight, organ weight, ROS, AST, ALT, TC, TG, HDL-C, LDL-C and lipid metabolism protein were checked. Results YGTL and YGTH group significantly reduced body weight compared to Veh group. YGTH group significantly reduced visceral fat weights compared to Veh group. In blood biochemistry analysis, ROS, AST, ALT, TC, TG and LDL-C in YGTL and YGTH group were significantly lower than Veh group. HDL-C increased significance in YGTL and YGTH group. In antioxidation protein analysis, Catalase, GPx and HO-1 have increased significantly in YGTL and YGTH group. YGTH group have increased $PPAR-{\alpha}$, p-AMPK compared to Veh group. but decreased FAS. SREBP-1, p-ACC levels in YGTL and YGTH group were decreased compared to Veh group, however CPT-1, UCP-2 levels in YGTL and YGTH group were increased compared to Veh group. Conclusions YGT has anti-obesity effects by regulating lipolysis and antioxidation in a diet-induced obesity model. Additional clinical studies are needed.

Purpose: Obesity is associated with morbidity following gastric cancer surgery, but whether obesity influences morbidity after laparoscopic gastrectomy (LG) remains controversial. The present study evaluated whether body mass index (BMI) and visceral fat area (VFA) predict postoperative complications. Materials and Methods: A total of 217 consecutive patients who had undergone LG for gastric cancer between May 2003 and December 2005 were included in the present study. We divided the patients into two groups ('before learning curve' and 'after learning curve') based on the learning curve effect of the surgeon. Each of these groups was sub-classified according to BMI (<$25kg/m^2$ and ${\geq}25kg/m^2$) and VFA (<$100cm^2$ and ${\geq}100cm^2$). Surgical outcomes, including operative time, quantity of blood loss, and postoperative complications, were compared between BMI and VFA subgroups. Results: The mean operative time, length of hospital stay, and complication rate were significantly higher in the before learning curve group than in the after learning curve group. In the subgroup analysis, complication rate and length of hospital stay did not differ according to BMI or VFA; however, for the before learning curve group, mean operative time and blood loss were significantly higher in the high VFA subgroup than in the low VFA subgroup (P=0.047 and P=0.028, respectively). Conclusions: VFA may be a better predictive marker than BMI for selecting candidates for LG, which may help to get a better surgical outcome for inexperienced surgeons.

The adipose tissue hormone leptin has been proposed to be involved in the regulation of flood intake and energy expenditure via thermogenesis by uncoupling protein(UCP) in brown adipose tissue(BAT). The objective of the study was to examine the effects of high fat diet on the serum leptin levels, BAT UCPl expression and the body fat mass in rats after weaning. During experimental period of 12 weeks, 4 male Sprague-Dawley rats were killed for the baseline experiment at 4 weeks of age while the remaining rats were fed the two different diets: the control diet AIN-76A(n = 20), high fat(beef tallow) diet(n = 20) ad libitum, which provided 11.7% or 40% of calories as fat, respectively. At 16 weeks of age, the increase in the food efficiency ratio(FER) was related to fat mass in rats on high fat diet. Serum leptin level was increased by age and dietary high fat. There was no difference in serum insulin level between groups until 10 weeks of age, but rats fed high fat diet for 12 weeks showed hyperinsulinemia. The amount of body fat pads was increased significantly in high fat group compared to normal diet group. Visceral fat mass affected acutely by high fat diet, as a result, it was higher in rats fed high fat diet for 2 weeks than normal diet. At 16 weeks of age, BAT and visceral fat mass were significantly high in high fat group. Also, the serum leptin levels reflected the amount of body fat mass. BAT UCPI mRNA expression increased with age and dietary high fat. This study demonstrates that dietary high fat increased serum leptin levels, BAT UCPI expression and body fat mass. Futhermore, in rats fed high fat diets, the increases in leptin and UCPI expression counteracts only in part the excess adiposity and obesity.
