  • The study was conducted to investigate the effects of dietary calcium and soy isoflavone on body fat and lipid metabolism in high fat-induced obesity. Four week old female C57/BL6J mice, known as a good model of diet-induced obesity, were fed low Ca and high fat diet for 6 weeks. After induced obesity, mice were divided into six groups according to diets varying calcium contents (0.1 or 1.5%) and genistein contents (0 or 500 or 1,000 ppm). Body weight, fat pad (perirenal fat and parameterial fat), adipocyte size, serum total lipid and total cholesterol were significantly decreased by both high Ca intake and genistein supplementation. However, the effect of genistein supplementation showed in low Ca-fed groups. Serum LDL-cholesterol and TG were significantly decreased by high Ca intake and genistein supplementation, respectively. In liver, lipogenic enzymes (fatty acid synthase and malic enzyme) activity and TG were significantly decreased by both high Ca intake and genistein supplementation. This inhibitory effect of genistein on lipogenic enzymes showed in low Ca-fed groups. But liver total cholesterol and total lipid were significantly decreased by high Ca intake and genistein supplementation, respectively. Fecal excretion of total lipid, total cholesterol and TG were significantly increased by high Ca intake, not by genistein supplementation. In conclusion, high calcium intake and genistein supplement may be beneficial for suppression of obesity through direct anti-adipogenesis by decreasing fat weight and size and indirect anti-lipo-genesis by inhibiting lipogenic enzymes activity and improving lipid profile.

  • Objectives & Methods : The purpose of this study is to observe the anti-oxidative effects of electroacupuncture to Yinlingquan(SP9) in AAPH induced oxidative stress of rats. The author performed several experimental items including measurements of body weight, levels of albumin, total bilirubin, LDL-cholesterol, GOT and GPT in serum, levels of SOD, glutathione, catalase, NO and MDA in liver, histological analysis of liver. The conclusions are as follows. Results : 1. In the SP9-EA group, the level of LDL-cholesterol was significantly decreased in comparison with that of the holder group and control group. 2. In the SP9-EA group, SOD activity, glutathione concentration in liver were increased, and NO concentration was decreased significantly in comparison with those of the control group and the holder group. 3. In the SP9-EA group, the density of liver tissue was maintained more similarly to the normal group in comparison with those of the control group and the holder group. 5. The results of the SP9-NR group showed similar tendencies with those of the SP9-EA group, but the effects were lower than those of the SP9-EA group. Conclusion : These results suggest that electroacupuncture at SP9 has an anti oxidative effect through suppressing both the reduction of anti-oxidative enzymes and production of oxidized substances.

  • BACKGROUND/OBJECTIVES: The main objective of this study was to evaluate the effects of a high cholesterol (HC) dietary challenge on cholesterol tissue accumulation, inflammation, adipocyte differentiation, and macrophage infiltration in guinea pigs. A second objective was to assess whether macronutrient manipulation would reverse these metabolic alterations. MATERIALS/METHODS: Male Hartley guinea pigs (10/group) were assigned to either low cholesterol (LC) (0.04g/100g) or high cholesterol (HC) (0.25g/100g) diets for six weeks. For the second experiment, 20 guinea pigs were fed the HC diet for six weeks and then assigned to either a low carbohydrate (CHO) diet (L-CHO) (10% energy from CHO) or a high CHO diet (H-CHO) (54% CHO) for an additional six weeks. RESULTS: Higher concentrations of total (P < 0.005) and free (P < 0.05) cholesterol were observed in both adipose tissue and aortas of guinea pigs fed the HC compared to those in the LC group. In addition, higher concentrations of pro-inflammatory cytokines in the adipose tissue (P < 0.005) and lower concentrations of anti-inflammatory interleukin (IL)-10 were observed in the HC group (P < 0.05) compared to the LC group. Of particular interest, adipocytes in the HC group were smaller in size (P < 0.05) and showed increased macrophage infiltration compared to the LC group. When compared to the H-CHO group, lower concentrations of cholesterol in both adipose and aortas as well as lower concentrations of inflammatory cytokines in adipose tissue were observed in the L-CHO group (P < 0.05). In addition, guinea pigs fed the L-CHO exhibited larger adipose cells and lower macrophage infiltration compared to the H-CHO group. CONCLUSIONS: The results of this study strongly suggest that HC induces metabolic dysregulation associated with inflammation in adipose tissue and that L-CHO is more effective than H-CHO in attenuating these detrimental effects.

  • The aim of this study was to investigate the effects of L-carnitine on the components of serum and liver and the effects on the anti-oxidant system. For this purpose, five experimental groups were setup. For fat source, perilla oil enough with unsaturated fatty acid and beeftallow enough with saturated fatty acid were supplemented together with L-carnitine to the rats. Five experimental groups kept eight Sprague-Dawley rats respectively, They were co group supplemented with basic diet or AIN-93, PO group supplemented with perilla oil, POC group supplemented with perilla oil and L-carnitine, BT group supplemented with beeftallow, and BTC group supplemented with beeftallow and L- carnitine. The results are. 1) Weight gain, food intake and FER were not different significantly among the experimental groups. 2) Significant difference was observed in serum total lipid(P<0.05), serum triglyceride(P<0.05), serum total cholesterol (P<0.05)and serum LDL cholesterol(P<0.05). Serum total lipid and serum triglyceride were significantly low in the groups supplemented with L-carnitine. Serum total cholesterol showed difference with the supplementation of L-carnitine in BTC only. LDL cholesterol showed no significant difference with the supplementation of L-carnatine, but total values of LDL-cholesterol were high in groups supplemented with beeftallow. 3) Total cholesterol in liver was low in POC group with the supplementation of L-carnitine however, there was no difference in BTC group with the supplementation of L-carnitine. In summary, dietary L-carnitine did not influence the weight gain, food intake and food efficiency ratio among the experimental groups, but had an effect of lowering the serum total lipid and triglyceride significantly in both groups which were supplemented with L-carnitine. The effect of lowering of sew total cholesterol with the supplementation of L-carnitine in beeftallow group(BTC) only. The effect of lowering of liver total cholesterol with the supplementation of L-carnitine in perilla oil group(POC) only.

  • BACKGROUND/OBJECTIVES: Nobiletin (NOB), a citrus flavonoid, is reported to have beneficial effects on cardiovascular and metabolic health. However, there is limited research investigating the effect of long-term supplementation with low-dose NOB on high-cholesterol diet (HCD)-induced hypercholesterolemia and non-obese nonalcoholic fatty liver disease (NAFLD). Therefore, we investigated the influence of NOB on hypercholesterolemia and NAFLD in HCD-fed mice. SUBJECTS/METHODS: C57BL/6J mice were fed a normal diet (ND) or HCD (35 kcal% fat, 1.25% cholesterol, 0.5% cholic acid) with or without NOB (0.02%) for 20 weeks. RESULTS: HCD feeding markedly reduced the final body weight compared to ND feeding, with no apparent energy intake differences. NOB supplementation suppressed HCD-induced weight loss without altering energy intake. Moreover, NOB significantly decreased the total cholesterol (TC) levels and the low-density lipoprotein (LDL)/very-LDL-cholesterol to TC ratio, and increased the high-density lipoprotein-cholesterol/TC ratio in plasma, compared to those for HCD feeding alone. The plasma levels of inflammatory and atherosclerosis markers (C-reactive protein, oxidized LDL, interleukin [IL]-1β, IL-6, and plasminogen activator inhibitor-1) were significantly lower, whereas those of anti-atherogenic adiponectin and paraoxonase were higher in the NOB-supplemented group than in the HCD control group. Furthermore, NOB significantly decreased liver weight, hepatic cholesterol and triglyceride contents, and lipid droplet accumulation by inhibiting messenger RNA expression of hepatic genes and activity levels of cholesterol synthesis-, esterification-, and fatty acid synthesis-associated enzymes, concomitantly enhancing fatty acid oxidation-related gene expression and enzyme activities. Dietary NOB supplementation may protect against hypercholesterolemia and NAFLD via regulation of hepatic lipid metabolism in HCD-fed mice; these effects are associated with the amelioration of inflammation and reductions in the levels of atherosclerosis-associated cardiovascular markers. CONCLUSIONS: The present study suggests that NOB may serve as a potential therapeutic agent for the treatment of HCD-induced hypercholesterolemia and NAFLD.

  • Anti-obesity effects of $\beta$-cyclodextrin in obese C57BL/6J mice induced by a high fat diet (HD) were observed. The administration of $\beta$-cyclodextrin reduced the gain of body weight, abdominal fat, liver weight, the lipid deposits of hepatocytes and the size of adipocytes in the HD group. In serum analysis, the total and low-density lipoprotein-cholesterols were significantly decreased in the $\beta$-cyclodextrin-supplemented HD group than in the HD group. However, high-density lipoprotein-cholesterol was not changed in these groups. In hypothalamic homogenates, the decrease of neuropeptide Y and increase of $\alpha$-melanocyte stimulating hormone were detected in the $\beta$-cyclodextrin-supplemented HD group compared to that in the HD group. These effects of $\beta$-cyclodextrin were similar to those of Garcinia cambogia, which is widely used as a natural anti-obesity product. These results suggest that $\beta$-cyclodextrin has anti-obesity effects through the lowering of the abdominal fat pad and inhibits the central effects of hunger.

  • Objectives : The researcher investigated the anti-obesity effect of Platycodi Radix (P), Platycodi Radix and Cyperi Rhizoma combination water extract (PC) in mice fed a high fat diet and focused on the analysis of local area adipose tissue.Methods : Male ICR mice were divided into four groups, which were fed either a normal AIN diet (N group), a high fat diet (HFD group), or a high fat diet and orally administration with a concentraion of 300 mg/kg body weight (P group or PC group) for eight weeks.Results : Compared to mice in the HFD group, mice in the P group or PC group showed significant reductions in weight gain and relative weight of total fat. Compared to mice in the HFD group, mice in the P group showed significant reductions in relative weight of liver. In blood biochemistry analysis, AST, ALT, triglyceride, total-cholesterol and low density lipoprotein(LDL)-cholesterol, AI levels of P group or PC group were significantly lower than those of the control group AI. But serum serum high density lipoprotein(HDL)-cholesterol levels from the P group or PC group were significantly higher than those of the HFD mice in serum. And serum adiponectin levels from the P group or PC group were significantly increased that those of the HFD mice. And adipocyte number in the fat tissue from the P group or PC group was significantly higher than those of the HFD mice.Conclusions : Platycodi Radix, Platycodi Radix-Cyperi Rhizoma have an anti-obesity effect in mice and the effect is mediated by inhibition of fat gain.
