Objectives The aim of this study was to determine the inhibitory effects of Bangpungtongsungsan extract (BTS) on fat accumulation in high-fat diet-induced young obese mice. Methods The extract was administered to 3-week-old C57BL/6 male mice fed with a high-fat diet. The experimental groups were divided into a control group (Ctrl), high-fat diet group (HFDF), and BTS treated group after high fat diet feeding (BTST), with 10 mice assigned to each group. Lipid synthesis was observed to confirm the inhibition of fat synthesis. Changes in body weight, body fat percentage, and total cholesterol in the blood were observed to confirm weight control. Peroxisome proliferator-activated receptor gamma (PPAR-γ) and sterol regulatory element-binding protein (SREBP)-1 positivity was observed to confirm the inhibition of fat accumulation in liver tissue. Results Bangpungtongsungsan significantly inhibited lipid synthesis. Changes in body weight, body fat percentage, and total cholesterol in the blood were significantly lower in BTST rats than in HFDF rats. PPAR-γ and SREBP-1 positivity were significantly lower in BTST rats compared to HFDF rats. Conclusions This study confirms the potential of BTST to inhibit fat accumulation in obesity.

This study was conducted to find out the effect of fermented milk on lowering of serum and liver cholesterol in high diet. Sprague-Dawley male rats of 200g initial average weight were assigned to four experimental group : (1) high fat diet + milk (2) high fat diet + bifidobacteria (3) high fat diet + microcapsulated bifidobacteria (4) high fat diet + fermented milk by bifidobacteria. Milk, bifidobacteria, microcapsulated bifidobacteria and fermented milk by bifidobacteria were given 2ml per day. According to the result, there was lowering effect of serum and liver total cholesterol in fermented milk feeding group, Serum LDL-cholesterol was also low tendency in fermented milk by bifidobacteria feeding group. Accordingly, it was confirmed that the material that caused hypocholesteremic effect was not the bifidobacteria itself in fermented milk but the metabolic material produced in the fermentation, and it inhibited cholesterol synthesis in liver.

This study was conducted to investigate the effects of shellfish on lipid metabolism in rats fed high fat supplements. Male sprague-dawley rats weighting approximately 165g were fed a basal diet, a high fat diet, or a high fat diet plus shellfish for 4 weeks. The shellfishes on the were oyster, hard-shelled mussel, little neck clam, and march clam. Alfter 4 weeks high fat diet, supplementation of 20% lard significantly increased plasma. GOT, GPT, ${\gamma}$-GTP , and liver triglyceride (TG). Plasma GOT, GPT, ${\gamma}$-GTP , triglyceride, and total cholestrerol levels were significantly lower in shellfish groups than in basal and high-fat groups regardless of high-fat supplementation (p<0.05). The total lipid and cholesterol content in liver showed similar results(p<0.05). There were no differences in glucose, HDL-cholesterol in plasma and total cholesterol and total lipid in liver between basal and high-fat supplemented diets. Liong chain fatty acids, specific components of shellfishes group, were exclusively higher than in basal and high-fat diets, and were most well-reflected in liver and plasma. From the above results, the hypolipidemic effects of shellfish were detected in the process of inducing hyperlipidemia by high-fat supplement.

The effect of feeding various diets on plasma lipids, liver lipids, fecal excretion of lipids and triglyceride secretion rate was studied in Sprague-Dawley rats fed for 1 month diets containing high fat(40% of energy ; HF) high cholesterol(1% ; HC), low fat/high sucrose(70% ; HS) or control diet(CT). Weight gain in HS group but there were no differences in TG contents of HF or HC groups compared to CT group. Fecal excretion of lipid was higher in HC than in HF, HS and CT groups. Hepatic TG secretion was not significantly different in four dietary groups. Accordingly, hypertriglyceridemia shown in HS group does not seem to be resulted from the increased TG secretion rate.

This study was to examine antioxidative effects of ginseng extracts on liver of high fat diet-treated mice. ICR male mice were given high fat diet with red ginseng or white ginseng extracts (500, 1500, 3000 mg/kg/day, orally) for 4 weeks. We also Investigated the relationship between lipid peroxidation and ginseng extracts on the oxidative stress. We measured the levels of malondialdehyde (MDA, a marker of lipid peroxidation), hydrogen peroxide, superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH) in liver tissue. The activities of SOD was generally low in all ginseng extract groups. But the activity of GPx was high in all ginseng extract groups. The hydrogen peroxide contents were similar in almost all groups. The level of GSH was higher in all ginseng extract group in high fat diet (FD) group. The levels of MDA (the end product of lipid peroxidation) were lower in all ginseng extract groups than in FD group. These results that the antioxidant effects of red ginseng and white ginseng extracts prevent oxidative damage by antioxidant effects involving SOD, GPx and increasing the ability of the body to synthesize endogenous antioxidants. It was concluded that ginseng can protect against oxidative stress by high fat diet through its antioxidant properties.

The effect of diet supplementation of Antheraea pernyi (A. pernyi) silk fibroin on the lipid metabolism and antioxidant defense status in high fat-fed mice was investigated. The animals were given normal control diet (NC group), high fat diet (HF group), or high fat diet supplemented with A. pernyi silk fibroin powder (HFS group) for 7 weeks. After the experimental period, the HF group showed significant increase in body weight, plasma and hepatic total cholesterol levels, and hepatic triglyceride concentration, and decreased activities of hepatic antioxidant enzymes relative to NC group. However, the HFS group exhibited marked reduction in body weight, plasma cholesterol and hepatic triglyceride levels, hepatic lipogenic enzyme activities, and lipid peroxidation rate, and higher high-density lipoprotein (HDL)-cholesterol level, fecal triglyceride content, and antioxidant enzymes activities compared with that of HF group. These findings demonstrate that dietary feeding of A. pernyi silk fibroin could improve the lipid metabolism and antioxidant defense system via regulation of hepatic antioxidant and lipogenic enzymes activities. Hence, this silk fibroin may be beneficial as a functional biomaterial for the development of therapeutic agent against high fat diet-induced hyperlipidemia and its related diseases.

The effects of liquid culture of Agaricus blazei Murill on the weight gains, serum and hepatic lipid concentrations were studied in male rats. Sprague-Dawley rats (7 weeks old) were given four different types of diets for 6 weeks, respectively: a normal diet group, a high fat control diet group (normal diet+15% lard +0.5% cholesterol), a 30% or 40% A. blazei diet groups (high fat control diet+30% or 40% A. blazei in water) according to the levels of A. blazei supplementation. The body weight gains, food intake, food efficiency ratios, and the liver, kidney, and epididymal fat pad weights of the rats fed 30% or 40% A. blazei diets were similar to those of the rats fed high fat control diet. The concentrations of serum total cholesterol, LDL-cholesterol and atherogenic index in rats fed the 30% or 40% A. blazei diets were significantly decreased compared with those of rats fed the high fat control diet. The HDL-cholesterol/total-cholesterol ratios of the rats fed 30% or 40% A. blazei diet were significantly increased compared with those of rats fed the high fat control diet. The fecal excretion of total lipid . in the rats fed 40% A. blazei diet was significantly increased compared with those of rats fed the high fat control diet. The concentrations of serum total lipid in the rats fed 40% A. blazei diet was significantly lower than that in the rats fed high fat control diet. But the concentrations of serum HDL-cholesterol, hepatic total cholesterol and triglyceride of rats fed the 30 or 40% A. blazei diets were similar to those of rats fed the high fat control diet. These results showed that the 30 or 40% A. blazei diets feeding decreased the total cholesterol, LDL-cholesterol and atherogenic index, and increased the HDL-cholesterol/total-cholesterol ratio in serum of rats.

This study evaluated the effect of biocellulose and the diet formulation on reducing body weight gain of obese rats induced by high-fat diet for 10 weeks. Thirty male Sprague-Dawley rats were randomly assigned to high-fat diet group (OB-CON), high-fat diet group containing 5% biocellulose (OB-BIO), and high-fat diet group containing 5% dietary formulation (OB-DF). After feeding each diet for additional 10 weeks, body weight gains of OB-BIO and OB-DF groups were lower by 3.3 and 4.8%, respectively as compared with that of OB-CON group. Although not significant, measured values of the perirenal and visceral fat pads of OB-BIO and OB-DF groups were lower than those of the OB-CON group. The weight of interscapular brown adipose tissue did not show significant difference in all groups. The size of adipocyte in rats was lower in both OB-BIO and OB-DF groups. Thus, biocelluose and the diet formulation showed the anti-obesity effect.

This study was conducted to investigate the effect of exercise training on blood and metabolic variances and genes expressions in hyperlipidemic rats. Three weeks-old male rats were randomly assigned into chow (n=7), high-fat diet (HF, n=7) and HF+exercise (HF+EX, n=7) groups. Exercise training consisted of the treadmill running 5 times per week during 8 weeks (0% grade, 30 min/time for first 4 weeks and 0% grade, 60 min/time the other 4weeks). The levels of triglyceride and total -cholesterol were increased in HF diet compared with chow group, and recovered to level of chow group by exercise training. Plasma glucose and insulin concentrations increased by 40 and 50%, respectively in HF diet compared with chow diet group, and these increases returned to the level of chow group by exercise training (p<.05). Body weight and abdominal fat mass were increased by high-fat diet compared with chow diet, and recovered to level of chow group by exercise training. Long-chain fatty acid oxidation rate and AMPK protein expression was not changed by HF diet, but increased by exercise training compared with high-fat diet (p<.05). UCP3 protein expression was not changed by either high-fat diet or exercise training compared with chow group. There was high correlation between plasma triglyceride and total cholesterol concentrations(p<.01). Plasma triglyceride or total cholesterol level showed correlation with following factors; plasma insulin and glucose levels, body weight, abdominal fat weight, UCP3 protein expression and long-chain fatty acid oxidation rate. These results showed that exercise training on the treadmill recovered hyperlipidemia, hyperglycemia and hyperinsulinemia induced by high-fat diet for 8 weeks. These exercise effects may be related with decreased body weight and abdominal fat mass, and increased long-chain fatty acid oxidation rate.

This study was performed to investigate the effects of genistein, a kind of soy isoflavones, on fatty liver and lipid metabolism in rats fed high fat diet. Twenty four male Sprague-Dawley rats were divided into four groups by dietary fat and genistein contents then raised for six weeks. The rats(n=6/group) were fed normal fat diet(NOR), high fat diet (HF), high fat with 0.1% genistein(HF+0.1%G) or high fat with 0.2% genistein(HF+0.2%G). Hepatic total lipid, triglyceride, total cholesterol and Serum GPT, as a marker for fatty liver, were significantly increased by high fat diet. Also, serum total lipid, triglyceride, total cholesterol, glucose and insulin concentration, hepatic lipogenic enzyme (fatty acid synthase and malic enzyme) activities were significantly increased by high fat diet. However, hepatic total lipid, triglyceride, total cholesterol and Serum GPT were significantly decreased by genistein intake. Also, genistein supplementation decreased serum total lipid, triglyceride, glucose and insulin concentration, hepatic lipogenic enzyme (fatty acid synthase and malic enzyme) activities. There were no differences by genistein level except for serum insulin. These results suggest that fatty liver induced by high fat diet was caused by increased serum lipid profiles and hepatic lipogenesis, whereas, genistein may be useful in inhibiting of fatty liver by reducing serum lipid profiles and hepatic lipogenesis.
