  • 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.

  • Purpose: The objective of the present study was to determine whether fermentation can increase the protective effects of blueberry liquid in a high-fat diet-induced obese mice model. Methods: Male C57BL/6J mice were fed a high-fat diet (HD, 60% fat, w/w,), HD supplemented with 10 ml/kg BW/day of blueberry liquid (BHD, blueberry high-fat diet), or HD supplemented with 10 ml/kg BW/day of fermented blueberry liquid (FBHD, fermented blueberry high-fat diet) for 10 weeks. Results: There were significant decreases in the body, epididymal adipose tissue, and liver weights of blueberry-fed groups compared to HD, whereas there were no significant differences in food intake among the groups. Furthermore, blueberry liquid groups, especially fermented blueberry liquid, significantly attenuated the contents of hepatic triglycerides and total cholesterol induced by HD. Serum LDL-cholesterol was significantly lower in the BHD and FBHD-fed groups, whereas FBHD significantly increased the serum HDL-cholesterol level compared to the control. Concentrations of aspartate transaminase, alanine transaminase, and leptins in serum were also reduced by blueberry liquid supplementation. The mRNA expression of hepatic acetyl CoA carboxylase was significantly reduced in both the BHD and FBHD groups compared to HD. Furthermore, FBHD altered the mRNA expression level of hepatic lipolysis genes. Conclusion: In conclusion, these results suggest that blueberry, especially fermented blueberry liquid, may improve obesity-related abnormalities.

  • This study was carried out to investigate the dietary effects of Monascus pilosus mycelial extract on obesity in high-fat with cholesterol-induced obese rat models. It was observed that M. pilosus mycelial extract contains $25.85{\pm}1.98mg%$ of total monacolin K without citrinin by highperformance liquid chromatography (HPLC). The rats were randomly divided into 2 groups; normal control and a high-fat with cholesterol diet group. The high-fat with cholesterol diet group was fed a 5L79 diet with an added 15% lard and 1% cholesterol supplemented diet for 3 weeks for induction of obesity. After induction, obesity was confirmed by checking obesity indexes, the animals were divided into 4 groups (n=5); first, the normal control (NC), and then taken from the obese model of rats, a high-fat with cholesterol diet obesity control group (HF), 0.5% M. pilosus mycelial extract supplemented high-fat with cholesterol diet group (MPMs), 2% conjugated linoleic acid supplemented high-fat with cholesterol diet group (CLA) for 7 weeks. Body weight gains, obesity indexes, and body fat contents in the experimental groups (MPMs and CLA) were decreased compared with HF group. Feed Efficiency Ratio (FER) in MPMs was significantly lower than that of HF without change of feed intake. These results suggested that the anti-obesity effects of the M. pilosus mycelial extracts (MPMs) could prevent obesity induced by high-fat with cholesterol diet possibly via inhibition of lipid absorption.

  • This study analyzed the antioxidant properties of Equisetum arvense and its effects on serum factor levels in mice fed a high-fat diet. The aim was to establish a new effective resource for biologically active materials. E. arvense stem and root extracts were obtained using deionized water at $95^{\circ}C$, and 70.5% ethanol at $85^{\circ}C$. These extracts were used to analyze the total phenolic compounds and antioxidant (ABTS, DDPH, and FRAP) activities. The effects of prepared ground samples were evaluated by feeding them to mice. E. arvense extracts showed strong antioxidant effects. The caffeic acid content was highest in the 70.5% ethanol extract of the vegetative stem, as determined by high-performance liquid chromatography. The blood concentrations of insulin and leptin were significantly lower in mice fed a high-fat diet supplemented with extracts of the root, reproductive stem, and vegetative stem of E. arvense than in mice fed only a high-fat diet. These results suggest that the polyphenolic compounds in E. arvense extracts exert various antioxidant effects. The stems and root of E. arvense can lower the blood levels of insulin and leptin, even after consumption of a high-fat diet.

  • We compared the preventive capacity of high intakes of vitamin C (VC) and vitamin E (VE) on oxidative stress and liver toxicity in rats fed a low-fat ethanol diet. Thirty-two Wistar rats received the low fat (10% of total calories) Lieber-DeCarli liquid diet as follows: either ethanol alone (Alc group, 36% of total calories) or ethanol in combination with VC (Alc + VC group, 40 mg VC/100 g body weight) or VE (Alc + VE group, 0.8 mg VE/100 g body weight). Control rats were pair-fed a liquid diet with the Alc group. Ethanol administration induced a modest increase in alanine aminotransferase (ALT), aspartate aminotransferase (AST), conjugated dienes (CD), and triglycerides but decreased total radical-trapping antioxidant potential (TRAP) in plasma. VE supplementation to alcohol-fed rats restored the plasma levels of AST, CD, and TRAP to control levels. However, VC supplementation did not significantly influence plasma ALT, AST, or CD. In addition, a significant increase in plasma aminothiols such as homocysteine and cysteine was observed in the Alc group, but cysteinylglycine and glutathione (GSH) did not change by ethanol feeding. Supplementing alcohol-fed rats with VC increased plasma GSH and hepatic S-adenosylmethionine, but plasma levels of aminothiols, except GSH, were not influenced by either VC or VE supplementation in ethanol-fed rats. These results indicate that a low-fat ethanol diet induces oxidative stress and consequent liver toxicity similar to a high-fat ethanol diet and that VE supplementation has a protective effect on ethanol-induced oxidative stress and liver toxicity.

  • This study was performed to investigate the effects of liquid culture of Agaricus blazei on the lipid metabolism and enzyme activities in growing male rats. Sprague-Dawley rats were given four different types of diets for a succeeding period of 5 weeks, respectively: a normal diet group (7% corn oil), a high fat diet group (7% com oil + 15% lard), a 20 or 30% Agaricus diet groups (high fat diet + 20 or 30% Agaricus in water) according to the levels of Agaricus supplementation. The body weight gains, food intake, food efficiency ratios, and hepatic, kidney, spleen and pancreas weights of the rats fed 20 or 30% Agaricus diets were similar to those of the rats fed high fat diet. The epididymal fat pad weight of the rats fed high fat diet and 20 or 30% Agaricus diets were significantly higher than that of the rats fed normal diet. The concentrations of serum triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol, and the activity of glutamic pyruvic transaminase in the rats fed 30% Agaricus diet were significantly lower than those in the rats 114 high fat diet. But the concentrations of hepatic total cholesterol and triglyceride of rats fed the 20 or 30% Agaricus diets were similar to those of rats fed the high fat diet. The HDL-oholesterol/total-cholesterol ratio of the rat fed 30% Agaricus diet was significantly higher than that of the rats fed high fat diet, The activity of glutamic oxaloacetic transaminase in the rats fed 20 or 30% Agaricus diets were similar to those in the rats fed high fat diet. There were no differences in the concentrations of total protein, hemoglobin and glucose, and the activities of alkaline phosphatase, and the atherogenic index in the serum among the experimental groups. These results showed that the 30% Agaricus diet feeding decreased the total cholesterol, the triglyceride and the LDL-cholesterol, and increased the HDL-oholesterol/total cholesterol ratio in serum of rats.

  • This study was designed to investigate the effect of age on the lipid metabolism in the rats fed different diets. In experiment A male Wistar rats of 5 weeks of age and of 32 weeks of age were divided into low fat diet groups and high fat-cholesterol groups. The rats were sacrificed 1 week, 2 weeks and 4 weeks after experiment begins. Also after 4 weeks. the rats in low and high fat diet groups were tube-fed 500mg of choelsterol and were sacrified 3 days later. In experiment b, male Wistar rats of 4 weeks of age and of 6 months of age were divided into 2 groups of butter and cron oil groups. And then eachgroup were divided into 2 subgroups ; meal feeding and nibbling groups . Each diet was fed for 4 weeks. In experiment A, age of the rats and experimental diets did not affect the serum cholesterol and triglycerides concentrations were higher in rats fed high fat cholesterol diet than in those fed low-fat or high -fat diets, but age of the animals had no effect on liver lipid content. The weight and cholesterol content of epidymal fat pad, however were higher in adult rats than in young ones regardless of the diets fed. When the rats were challenged with 500mg cholesterol, the rates of increase in serum and hepatic cholesterol level were higher in adult rats compared to young rats regardless of the diets . On the other hand, the rate of increase of small intestinal cholesterol content was lower in adult rats than in young rats. In experiment B, serum cholesterol and triglyceride content were relatively higher in young rats than adult ones. Stored body lipid was higher in adult rats, as judged by epididymal fat pad weight and total carcass lipid. Meal frequency and the kinds of fat in the diet did not affect the serum choelstero concentration . The serum triglyceride levels. however, was higher in butter fed rats thancron oil fed ones. The cholesterol content of live rand epididymal fat pad was lower in butter fed groups than corn oil groups for both young and adult rats, but there was no difference in liver triglycerides livel.

  • Poly-gamma-glutamic acid ($\gamma$-PGA) is a mucilaginous and biodegradable compound produced by Bacillus subtilis from fermented soybeans, and is found in the traditional Korean soy product, cheongkukjang. This study was carried out to evaluate the effects of $\gamma$-PGA from a food source on the concentration of the neurotransmitter GABA and its metabolic precursor glutamate in diet-induced obese rats. Eight-week old male Sprague-Dawley rats (n=60) were used. The rats were divided into two groups and obesity was induced by providing either a 10% control fat or 45% high fat diet for 5 weeks. The rats were then blocked into 6 groups and supplemented with a 0.1% $\gamma$-PGA diet for 4 weeks. After sacrifice, brain and serum GABA and glutamate concentrations were analyzed by high performance liquid chromatography with fluorometric detection. The rats fed the high fat diet had significantly increased body weights. $\gamma$-PGA supplementation significantly increased serum concentrations of glutamate and GABA in the control fat diet groups while this effect was not found in the high fat groups. In the brain, glutamate concentrations were significantly higher in the $\gamma$-PGA supplemented groups both in rats fed the normal and high fat diets than in the no $\gamma$-PGA controls. GABA concentrations showed the same tendency. The results indicated that $\gamma$-PGA intake increased GABA concentrations in the serum and brain. However, the effects were not shown in obese rats.

  • The effects of liquid culture of Coriolus versicolor on weight gain, food intakes, food efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in growing male rats. Sprague-Dawley rats were given four different types of diets for a succeeding period of 5 weeks, respectively: a normal diet group (7% corn oil), a high fat diet group (7% corn oil+15% lard), a 20% or 30% C. versicolor diet groups (high fat diet+20% or 30% C. versicolor in water) according to the levels of C. versicolor supplementation. The body weight gains of the rats fed the 30% C. versicolor diets were lower than those in the rats fed high fat diet. The epididymal fat pad weight of the rats fed high fat diet and 20% or 30% C. versicolor diets were significantly higher than that of the rats fed normal diet. The concentrations of triglyceride in the serum and the liver of the rats fed the 30% C. versicolor diets were more significantly decreased compared to rats on the high fat diet. The concentrations of total cholesterol in the serum and the liver of rats fed the high fat diet, 20% and 30% C. versicolor diets were similar to those of rats fed the normal diet. The HDL-cholesterol concentration and the HDL-cholesterol/total-cholesterol ratio of the rats fed 20% and 30% C. versicolor diets were significantly lower than those of the rats fed high fat diet. But the antherogenic index of the rats fed 20% or 30% C. versicolor diets were significantly higher than those of the rats fed high fat diet. There were no differences in the activities of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and alkaline phosphatase in the serum among the experimental groups. These results showed that the 30% C. versicolor diet feeding decreased the triglyceride in serum and liver of the rats.
