The present study was performed to investigate the effect of cereal fiber on lipid concentration of liver and serum in rats. Male Sprague-Dawley rats weighing 180$\pm$4g were divided into five groups by completely randomized block design : R, BR, B, W, and F. Each group fed a diet containing 0.7% cholesterol and a kind of cereal among rice(R), brown rice(BR), barley(B), whole wheat(W), and wheat flour(F) for 5 weeks. The results were summarized as follow : 1) Food intake. weight gain and feed efficiency ratio were not significantly different among the groups. 2) Fecal wet weight and dry weight were significantly higher in W group which fed the most amount of IDF(insoluble dietary fiber). 3) The weight of large intestine was significantly heavier in the W group compared to the others. But the weights of liver, stomach and small intestine were not significantly different among the groups. 4) Total lipid. triglyceride(TG) and total cholesterol(TC) content in liver were significantly different among the groups. The values were the lowest in the B group whose intake of SDF(soluble dietary fiber) was the highest 5) TC content in serum was not significantly different among the groups. TG content in serum was significantly lower in the rest groups than in the R group. HDL-c and free-c content in serum were significantly higher in the B group than in the rest groups. HDL-c/LDL-c, free-c/ester-c ratio were the highest in the B group but not significant. Above results show that the dietary fiber contained in cereals has physiological effects and they are different depending on fractions, IDF and SDF.

The study carried out to clarify the effects of lard and corn oil on serum total cholesterol content and liver thiobarbituric acid (TBA) value in ethanol (Et-OH) fed mice. Results obtained from the present study were a follows: 1. serum total cholesterol content was considerably increased by 25% Et-OH administration in mice. In case of 25% Et-OH plus Lard group and Lard group both group were also increased significantly to compare with normal value of mice but 25% Et-OH plus lard group was shown very higher value rather than that of Lard group and Lard group was found similar tendency to compare with the 25% Et-OH plus saline group except to after the 1 day. 2. serum total cholestrol content of 25% Et-OH plus Corn oil group and corn oil group were also increased significantly to compare with normal value, but the 25% Et-Oh plus Corn oil group slightly higher level than that of Corn oil group except to after the 3 days. 3. Lard group was also very similar tendency to compare with the corn oil group except to the 3 days. 4. liver TBA value was increased by 25% Et-OH fed mice. 25% Et-OH plus Lard group and Lard group were also increased significantly to compare with liver TBA value in normal mice, but 25% Et-OH plus Lard group was found higher value rather than that of lard group and 25% Et-OH group (Control). Lard group was similar to that of Control group except to after the 1 day. And 25% Et-OH plus Corn oil group was considerably increased rather than that of Control group, and liver TBA value of the above group was similar to that of 25% Et-OH plus Lard group except to after the 3 days. Corn oil group was shown lower value than that of lard group, but it was no significant.

The present study was conducted to evaluate the effect of fermented chub mackerel extract (FCME) on lipid metabolism in rats fed diets without cholesterol. Four week-old male rats were divided into three groups of 10 rats with 0, 1% or 2% FCME supplementation to the diets. Purified diets were used in the present study. Feed and water were fed ad libitum. FCME supplementation had no effect on the activities of acetyl-CoA carboxylase, fatty acid synthetase, and the content of free cholesterol, triglyceride and phospholipid in the liver (p>0.05). 1% FCME supplementation significantly increased serum triglyceride (p<0.05) and hepatic 3-hydroxy-3-methylglutaryl-CoA reductase activity (p<0.05) with no effect on serum total cholesterol, free cholesterol and phospholipid concentration. FCME supplementation significantly reduced serum LDL+VLDL-cholesterol (p<0.01) and atherogenic index (p<0.01) with no effect on HDL-cholesterol. The current study showed that FCME inclusion might reduce the risk of atherosclerosis in rats fed diet without cholesterol.

This study was carried out to determine the effects of Jerusalem artichoke (JA) powder , JA extract and chicory extract on lipid metabolism in SD rats. The experimental groups were divided into 4 groups ; control, JA powder JA extract and chicory extract. The animals were fed ad libitum each of the experimental diets for 3 weeks. After 3 weeks, the wet weights of cecum were significantly increased in rats fed JA powder and chicory extract. Cecal contents were slightly increased in all experimental groups. Serum HDL-cholesterol, HDL-cholesterol/total cholesterol ratio and atherogenic index were significantly increased in the chicory extract group. Serum triglyceride, total cholesterol and LDL-cholesterol levels were not different among the diet groups. Although the feeding of chicory extract significantly lowered total lipid of liver, there was no difference in levels of triglyceride and total cholesterol. The content of fecal lipiid and cholesterol were significantly higher in the Ja extract and chicory extract group than other groups. Fecal bile acid was significantly increased in the chicory extract group. These results indicate that chicory extract is an effective regimen for improvement of lipid metabolism in SD rats.
