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.

This experiment was made in order to observe the change in contents of the total cholesterol, free cholesterol and ester cholesterol in the liver and serum by the feeding of glucose and sucrose. The animals used for the experiment were adult male albino rat from a pure strain, weighing 285-332g. The animals were divided into standard, glucose and sucrose diet groups. The glucose and sucrose diet groups were redivided into 10%, 25% and 40% diet groups. Their liver and serum were used as sample after they were fed with the corresponding diets, respectively, for two months. 1. In the liver, the total cholesterol and ester cholesterol contents in the 40% glucose diet group were significantly increased and the free cholesterol contents in all diets were respectively increased, compared with the standard diet group. 2. In the serum, the total cholesterol contents in both diet groups, the 10% glucose and 10% sucrose, were decreased but the content in the 40% sucrose diet group was increased, compared with the standard diet group. The free cholesterol contents in the 10 and 40% glucose diet and 10% sucrose diet group were decreased, compared with the standard diet group. The ester cholesterol contents in the 10% glucose and 10% sucrose diet groups were decreased but the content in the 40% sucrose diet group was increased, compared with the standard diet group. Being taken into consideration of the above facts it was acquired that the cholesterol contents are affected by the amounts and kinds of dietary carbohydrate when the protein contents in each diet were constant.

The aim of this study is to evaluate the effect of Porphyra tenera (PT) extract on serum lipids content in ovariectomized rats. From day 3 until 42 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovarjectomized rats supplemented with PT at 50 mg/kg bw/day (OVX-PT50), 200 mg/kg bw/day (OVX-PT200). The PT ethanol extract were orally administrated at 1 m1 per day. Body weight gain, food intake and food efficiency ratio were not significantly different between groups. Although total-cholesterol was increased in OVX-control, supplementation with the PT decreased the level of cholesterol in serum. Especially, it was significantly decreased in OVX-PI50 (p＜0.05). Triglyceride was significantly decreased to almost all of groups supplemented with PT (p＜0.05). The levels of HDL-cholesterol was higher in PT extract group than OVX-control. These results suggest that supplementation with the PT extract positively influenced on lipid concentration in serum. Consequently, we expect that PT extract decrease risk of cardiovascular diseases by postmenopausal.

This study was designed to investigate the effect of dietary vitamin E levels on lipid metabolism in caffeine-fed rats. Male Sprague-Dawley rats were fed on diet containing one of three levels of vitamin E(37.5, 750, or 1,500mg/kg diet0 which was with or without 0.3% caffeine. The rats were sacrificed after 5 and 10 weeks of the feed periods. Results obtained from this study were as follows ; Net weight gain, feed intake and FER in the caffeine added groups were significantly decreased as compared to those of only vitamin E fed group. Liver and kidney weights tended to increase in the caffeine added groups, but spleen and heart weights were not affected. Total lipid contents in serum and liver tended to decrease as dietary vitamin E became increasing and caffeine diet adding. Serum total cholesterol content tended to increase in the caffeine added group. But, liver cholesterol content were decreased. And the higher the dietary vitamin E level became, the lower serum and liver cholesterol contents were. Serum and liver triglyceride contents were significantly lower in the caffeine added groups than in the only vitamin E fed groups. The degree of decrease was more evident as dietary vitamin E level became more increasing. Serum aminotransferase activity was not affected in all experimental groups.

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.
