In this study, we aimed to investigate the effects of dietary supplementation with fruiting body of Agaricus brasiliensis (AB) mushroom on the lipid profiles of serum and histological patterns of liver of high cholesterol-fed rats. Five-week-old, female Sprague-Dawley albino rats were divided into three groups of 8 rats each, including a normal control-diet (NC) group, a high-cholesterol diet (HC) group, and a group fed high-cholesterol diet supplemented with 5 % powder of Agaricus brasiliensis fruiting bodies (HC+AB). Total serum cholesterol, low density lipoprotein (LDL), and triglyceride (TG) concentrations in the HC+AB group were significantly reduced when compared with those in the HC group. Body weight in the HC+AB group was significantly lower than that in the HC group, whereas no adverse effects were observed on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. In the HC+AB group, liver enzyme activities related to liver function, such as GOT and GPT, presented values lower than those in the HC group and were very similar to the ones in the NC group. Excretion of total lipid and cholesterol in feces in the HC+AB group was significantly higher than that in the NC and HC groups, indicating that mushroom feeding inhibits the absorption of lipid cholesterol in the intestine. Liver histopathological analyses revealed that rats fed with HC diet developed fat liver disease, whereas only small amounts of fat were deposited in the livers of the HC+AB group. In conclusion, the results suggest that fruiting body powder of A. brasiliensis provides health benefits to high-cholesterol-fed rats by lowering body weight and the risk of atherogenic lipid profile.

In the present study, we examined the effects of a mixture of three strains, Lactobacillus plantarum CECT 7527, 7528, and 7529 (L. plantarum mixture), on body weight and lipid metabolism in Sprague-Dawley rats fed a high-fat diet. Rats were fed a high-fat diet and subjected to oral gavage with vehicle or the L. plantarum mixture ($0.6{\times}10^9$, $1.2{\times}10^9$, $2.4{\times}10^9$ colony-forming units (CFU)/day/rat, respectively) for 8 weeks. In rats fed a high-fat diet, oral administration of $2.4{\times}10^9CFU/day$ of the L. plantarum mixture significantly reduced body weight gain as well as weights of liver and epididymal fat. Leptin levels in sera were significantly reduced by oral administration of $2.4{\times}10^9CFU/day$ of the L. plantarum mixture. The L. plantarum mixture ($1.2{\times}10^9$ or $2.4{\times}10^9CFU/day$) also reduced the concentrations of total cholesterol and LDL-cholesterol in sera when it administered orally. Further, the L. plantarum mixture significantly reduced the atherogenic index and cardiac risk factor. In addition, oral administration of $2.4{\times}10^9CFU/day$ of the L. plantarum mixture markedly reduced levels of total lipids, triglycerides, and total cholesterol in the liver. The results of this study indicate that the L. plantarum mixture may exhibit anti-obesity and cholesterol-lowering effects, which suggest that the L. plantarum mixture has the potential to be a probiotic in the management of obesity and hypercholesterolemia.

The objective of this study was to determine the effect of herb and bio ceramic complex supplementation on growth performance and meat quality characteristics in finishing pigs. Seventy-two crossbred (Landrace ${\times}$ Yorkshire ${\times}$ Duroc) pigs (78.98kg average initial body weight) were used in a 45 days growth assay. Dietary treatments included 1) Control (basal diet). 2) HBC (Herb and bioceramic complex) 0.1 (basal diet + 0.1% Herb and bioceramic complex) and 3) HBC 0.2 (basal diet +0.2% Herb and bioceramic complex). For overall period, ADG (Average Daily weight Gain), ADFI (Average Daily feed Intake) and ADG/ADFI increased in Control with no significant difference (p>0.05). Backfat thickness was not significantly different among the treatments (p>0.05). The total cholesterol, HDL (High Density Lipoprotein) cholesterol, LDL (Low Density Lipoprotein) cholesterol, LDL + VLDL (Very Low Density Lipoprotein) cholesterol, Triglyceride and Atherogenic index concentrations of serum in pigs fed HBC 0.2 diet were lower than those of pigs fed Control and HBC 0.1 diets without significant difference (p>0.05). L$\^$*/-, a$\^$*/-, and b$\^$*/- values of M. longissimus dorsi muscle were not significantly different among the treatments (p>0.05). The pH of pigs fed HBC 0.2 diet was significantly lower than that of pigs fed Control and HBC 0.1 diets (p<0.05). In conclusion, growth performance, cholesterol concentration in serum and meat quality were not affected by supplemental herb and bioceramic complex.

This study was conducted to examine the effects of feeding diets containing bioorganic power (BP) flour, wheat flour and rice flour on blood glucose and lipid level in streptozotocin-induced diabetic rats. BP flour was composed with the mixture of defatted flour (16 g soybean, 12 g wheat, 8 g barley), 2 g red ginseng and 2 g whole wheat flour per 100 g diet. Experimental groups were divided into non-diabetic normal and 4 diabetic groups containing control, 40% BP, 41.6% wheat and 41.6% rice flours with basal diet. BP group was significantly increased body weight gain and decreased plasma glucose compared with the diabetic control, wheat and rice flour groups (p<0.05). Food efficiency ratio of diabetic rats were significantly lower than that of the normal rats. The concentrations of total cholesterol and triglyceride in plasma and atherogenic index were significantly decreased in BP, wheat and rice diabetic groups than diabetic control (p<0.05). The concentration of total cholesterol and triglyceride in liver was significantly lower in BP group as compared with the diabetic control, wheat and rice flour groups (p<0.05). In conclusion, the results indicated that BP flour feeding improved plasma glucose level, total cholesterol and triglyceride in diabetic rats.

This study investigated the lipid profiles for the possible improving activity of insoluble dietary fiber extracted from cabbage waste discarded during kimchi manufacture and market distribution. Enzyme-treated Insoluble Dietary Fiber (EIDF) is the remnants of crude dietary fiber (CDF) treated by ${\alpha}$-amylase, protease, and amyloglucosidase after removal of soluble materials from cabbage waste. The insoluble dietary fiber of CDF and EIDF in cabbage waste was $65.33{\pm}0.33%$ and $73.57{\pm}0.09%$, respectively. To examine the effects of EIDF on plasma cholesterol concentration, two group of rats were fed either a high fat diet (HFD) or a HFD containing 0.1~1.0% EIDF for 4 weeks. The body weight of all groups was not significantly different (p<0.05) but the body weight of EIDF+HFD groups was less than that of the HFD group (p<0.1). Compared with the HFD group, EIDF also lowered serum levels of total triglycerides to 11.2~23.3% and cholesterol to 26.8~28.5%. In EIDF+HFD groups, the HDL-cholesterol level increased by 7.2~26.1%, while LDL-cholesterol especially decreased by 51.0~61.4% and VLDL-cholesterol by 16.9~26.4%. The atherogenic index of EIDF+HFD groups was also reduced twice that of the HFD group. From these results, EIDF from cabbage waste could be a potential effective food ingredient for improving lipid profiles.
This study was conducted to investigate the effect of protein kinds and levels on lipid metabolism in hypercholesterolemia rats. Male Sprague Dawley rats were administrated 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia and were fed on diet containing two levels(7, 20%) of casein and soy protein respectively. The rats were sacrified after 5 weeks of feeding periods. Total lipid content in serum was decreased in proportion to level of protein and soy protein was more effective than casein in lipid-lowering effect. Serum triglyceride content was significantly decreased in proportion to level of protein and did not show significance by protein kind. Serum phospholipid content was more significantly decreased in 20% protein groups than that of 7% protein groups. Total cholesterol content in serum was significantly decreased by protein and were decreased in proportion to level of soy protein. Free cholesterol content did not show significance by protein level. The degree of decrease predominated in soy protein groups. Serum HDL-cholesterol content and RL-cholesterol were increased in proportion to level of protein and effect of soy protein was not more significantly than that of casein. Atherogenic index was significantly decreased in proportion to level of protein and soy protein groups were more effective. Serum LDL-, VLDL-cholesterol contents were more significantly decreased in 20% protein groups than that of 7% protein groups. Serum $\beta$-lipoprotein and chylomicrone-cholesterol contents also showed significantly decrease by soy protein.
This study was conducted to examine the effects of Cheonggukjang powder made using black foods on liver function and lipid composition in streptozotocin(STZ)-induced diabetic rats. The experimental animals were divided into 5 groups and fed the following for 7 weeks; normal diet(control), STZ+normal diet(Diabetic), STZ+50% soybean Cheonggukjang supplementation(DSC), STZ+44.5% yakkong Cheonggukjang supplementation(DYC), and STZ+supplementation with 50% yakkong black food(black rice, black sesame seeds, and sea tangle) Cheonggukjang(DYCB). The results showed that the body weight gain and food efficiency ratio of the STZ-induced diabetic groups were significantly lower than those of the control group. In the Diabetic group, glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) activities and total bilirubin content in serum were significantly greater than those in the control group. However, supplementation with Cheonggukjang reduced these values. In the Diabetic group, the triglyceride, total cholesterol, and low-density lipoprotein(LDL)-cholesterol contents in the serum and liver tissue, as well as the atherogenic index(AI) and cardiac risk factors(CRF) were significantly higher than the corresponding values in the control group, although the high-density lipoprotein(HDL)-cholesterol and phospholipid contents were significantly lower than those in the control group. However, supplementation with Cheonggukjang normalized the changed lipid composition in the STZ-induced diabetic rats. Further, yakkong Cheonggukjang and black food contaning yakkong Cheonggukjang normalized AI and CRF.

The effect of dandelion leaf extracts on lipid metabolism was investigated in high cholesterol-fed rats. Four groups of rats were given a high cholesterol diet containing 10g cholesterol/kg and 2.5 g sodium cholate/kg for 6 weeks. The control group received without dandelion leaf extracts and the other three groups received with one of dandelion leaf extracts (water, ethyl acetate, ether), respectively. Weight gain and feed intake were significantly higher in water group than control group. Serum triglyceride, total cholesterol, cholesteryl ester, chylomicron and VLDL-cholesterol concentratins were lower, whereas HDL-cholesterol and phospholipid concentrations were significantly higher in dandelion leaf extract supplemented-groups than control group. Dandelion extract increased HDL-C/total-C ratio and lowered atherogenic index. Hepatic triglyceride, total cholesterol, free cholesterol and cholesteryl ester concentrations lowered in dandelion leaf extract groups compared to control group. Especially, hepatic triglyceride and free cholesterol levels were lower in ethyl acetate extract group than in water and ether extract groups. Dandelion leaf extract supplements did not affect hepatic phospholipid cencentration. Hepatic HMG-CoA reductase activity was significantly lower in water extract group than the others. ACAT activity was significantly decreased by dandelion extract supplements.
This study was conducted to investigate the effect of soy protein hydrolyzate on lipid metabolism and antioxidant activity in the rat. Thirty-eight male rats of Sprague-Dawley strain were divided into five groups: casein, isolated soy protein (ISP), seoritae protein hydrolyzate (SH), soluble soy protein hydrolyzate (SS), and insoluble soy protein hydrolyzate (IS). The control diet (casein group) contained 20% casein protein and experimental diet contained 10% casein and 10% isolated soy-protein or soy-protein hydrolyzate. Fecal lipid content was increased and lipid apparent absorption rate was decreased significantly by the ISP group at the first week of experimental period. Blood triglyceride, total cholesterol, LDL-cholesterol and atherogenic index (AI) were decreased by soy protein hydrolyzate groups than casein group. Liver total lipid, triglyceride and cholesterol were not different among groups, but showed decreasing tendencies in soyprotein hydrolyzate groups. The lipid lowering effect was prominent in the IS group among soy protein hydrolyzate groups. Total antioxidant activity showed increasing tendency in the seoritae hydrolyzate group. Liver superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase activities also showed higher tendencies in the seoritae hydrolyzate group than other groups. In conclusion, insoluble soyprotein hydrolyzate was more effective in lowering body lipids and seoritae hydrolyzate had higher antioxidant capacity among soy protein hydrolyzates.

The purpose of this study is to verify the relation between vegetarian diet and the risk factors of cardiovascular disease. To do the present study the vegetarians were selected; 127 Buddhist nuns (age : 23 ~ 79 yrs) from Oonmoon Temple in Choungdo District, Gyeongsang Book-do. For control subjects, 235 healthy female adults (age : 23~79yrs) were selected. They were the teachers, the nurses of the hospital of Gyeongsang National University and the housekeepers living in Chinju Gyeongsang Nam-do. This study was conducted from October 1996 to February 1997. The contents are consisted of anthropometric measurement, questionnaries about eating behavior and intake frequency of food group and clinical examination. The results were summarized as follows. The average ages of vegetarians and non-vegetarians were 44.2 yrs and 40.5 yrs respectively. Average body mass index (BMI) of vegetarians and non-vegetarians were 22.4 and 21.0, WHR were 0.8 and 0.8, percentage of body fat were 28.7 and 26.5 and the average duration of vegetarian diet of the vegetarians was 13.1 years. Eating behavior score of vegetarian was significantly higher than those of non-vegetarians. Eating behavior score was negatively of correlated with levels of serum total-cholesterol, LDL-cholesterol and atherogenic index (AI). In intake frequency of green vegetable, lemon-yellow vegetable, bumb and seaweeds of the vegetarians more than those of non-vegetarians. Levels of total cholesterol, LDL-cholesterol, AI, diastolic blood pressure, blood sugar and HDL cholesterol of non-vegetarians were significantly higher (p<0.01) than those of vegetarians, but ratio of HDL cholesterol/total-cholesterol was lower in non-vegetarians. Consequently, vegetable diet can be considerably diet help to decrease the risk of cardiovascular disease.
