  • Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.

  • Background: An imbalance in energy intake and expenditure can cause obesity, which is a major risk factor for chronic diseases such as heart disease, type 2 diabetes, insulin resistance, cancers and hyperlipidemia. Methods and Results: In this study, we evaluated the anti-obesity effects of a water extract from the young leaves of barley sprout (BS) in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice (HF). Lipid accumulation measurement indicates that BS markedly inhibited adipogenesis by reducing lipid droplet production in a dose-dependent manner. Furthermore, the mRNA expression of adipogenic transcription factors peroxisome proliferator-activated receptor-${\gamma}$ and fatty acid synthetase, CCAAT/enhancer binding protein-${\alpha}$ and fatty acid binding protein 4 in 3T3-L1 cells was significantly inhibited by BS treatment. In an in vivo test, the BS-administered group of HFD-induced mice showed less body weight gain, and lower liver and epididymal white adipose tissue weights. The BS-treated mice showed decreased serum levels of leptin and lipids compared to untreated HFD mice and the levels of adiponectin and the HDL-cholesterol/total cholesterol ratio increased. These results indicate that BS inhibits body fat accumulation by reducing the mRNA expression of lipogenesis transcription factors and increasing serum adipokine concentration in in vitro and in vivo tests. Conclusions: BS reduced high fat diet-induced weight gain and had a positive effect on dyslipidemia.

  • Objective This study was designed to investigate the effects of Gamiygin-tang (GY) extract (GYE) and fermented solution (GYF) on body weight, serum lipid level and adipocyte differentiation in high fat diet-fed obese mice. Materials and Methods High fat diet-fed obese mice and 3T3-L1 adipocytes mice were treated with GYE and GYF and obesity related markers were assessed. A cytotoxicity assay was carried out by MTS assay. Inhibitory effects of GYE and GYF on adipocyte differentiation were carried out by Oil Red O staining. The effects of GYE and GYF on the expression of adipocyte differentiation regulatory factors, peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) and CCAAT/enhancer binding protein alpha (CEBP-${\alpha}$) were measured by real-time reverse transcriptase-polymerase chain reaction. The effects of GYE and GYF on the expression of adipocyte differentiation regulatory factors were also determined in relation to protein production/protein levels by western blotting. The anti obesity effects of GYE and GYF were measured in high fat-diet induced obese mice. Various factors were measured from the serum of the high fat-diet mice. Results Though GYE did not show toxicity at the concentration of 1mg/ml, GYF showed toxicity at the concentration of 1mg/ml. The GYE at 0.1 and 1mg/ml inhibited the differentiation of 3T3-L1 cells, and the GYF also inhibited the differentiation of 3T3-L1 cells. The effect of GYE on adipocyte differentiation factors including PPAR-${\gamma}$ and CEBP-${\alpha}$ was investigated and compared to the corresponding concentration levels of GYF. GYE and GYF both suppressed the RNA and protein levels of adipocyte differentiation factors. In the animal test both GYE and GYF reduced weight gain. GYE and GYF reduced blood cholesterol, TG and LDL levels. GYF better reduced blood cholesterol levels. Conclusions These results demonstrate that GYE and GYF exerts anti-obesity effect in 3T3-L1 cells and obese mice induced by high-fat diet.

  • In order to investigate the anti-obesity effects of Gambibang-2(here in after referred to GBB2) on the obese gene and obese inhibitory, C57BL/6 mice were induced by high fat diet. C57BL/6 mice were divided into four groups(normal, high fat diet with control, high fat diet with Reductil(here in after referred to RDT), high fat diet with GBB2 extract) and fed for 8 weeks. And observed that, body weight change, the weight change of the adipocytes in body and liver, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, glucose, leptin change in the serum, the expression of ${\beta}3AR$ and leptin gene in 3T3 cell and primary adipocyte cell, histological analysis of adipose tissue and liver tissue. GBB2 and RDT group showed that the revelation of ${\beta}3AR$ in primary adipose cell and 3T3 cell were increased considerably, and that the revelation of leptin in primary adipose cell and 3T3-L1 cell were decreased considerably. GBB2 and RDT group showed that the body weight were decreased considerably after 7-8 weeks. GBB2 and RDT group showed that the weight of adipocyte and liver were decreased. GBB2 and RDT group showed that the amount of HDL-Cholesterol were increased, the amount of glucose, LDL-Cholesterol and Triglyceride were decreased considerably. GBB2 group showed that the amount of leptin in the serum were decreased. GBB2 and RDT group showed that the size of adipocyte in adipocytes tissue and the adipose vacuoles in liver tissue were decreased. Taking all these observations into account, GBB2 considered to be effective in treating on the obese gene and obese inhibitory. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • Korean pine nut oil (PNO) has been reported to have favorable effects on lipid metabolism and appetite control. We investigated whether PNO consumption could influence weight gain, and whether the PNO-induced effect would result in an improvement of immune function in high-fat diet (HFD)-induced obese mice. C57BL/6 mice were fed control diets with 10% energy fat from either PNO or soybean oil (SBO), or HFDs with 45% energy fat from 10% PNO or SBO and 35% lard, 20% PNO or SBO and 25% lard, or 30% PNO or SBO and 15% lard for 12 weeks. The proliferative responses of splenocytes upon stimulation with concanavalin A (Con A) or lipopolysaccharide (LPS), Con A-stimulated production of interleukin (IL)-2 and interferon (IFN)-${\gamma}$, and LPS-stimulated production of IL-6, IL-$1{\beta}$, and prostaglandin $E_2$ ($PGE_2$) by splenocytes were determined. Consumption of HFDs containing PNO resulted in significantly less weight gain (17% less, P < 0.001), and lower weight gain was mainly due to less white adipose tissue (18% less, P = 0.001). The reduction in weight gain did not result in the overall enhancement in splenocyte proliferation. Overall, PNO consumption resulted in a higher production of IL-$1{\beta}$ (P = 0.04). Replacement of SBO with PNO had no effect on the production of IL-2, IFN-${\gamma}$, IL-6, or $PGE_2$ in mice fed with either the control diets or HFDs. In conclusion, consumption of PNO reduced weight gain in mice fed with HFD, but this effect did not result in the overall improvement in immune responses.
