This study was divised to observe the effects of defatted(by petroleum ether) Korean ginseng on the cholesterol level of Sprague-Dowley Albino male rats by alternating the diet. 130 heads of weaned rats having 83$\pm$4g of body weight were fed with each stock diets supplemented with 0.5, 1.0 and 3.0% defatted ginseng powder for 4 or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Total cholesterol and free form cholesterol contents in serum, liver and aorta of them were determined, and compared with the each corresponding group which was fed with defatted ginseng control diet for 12 weeks. Total cholesterol and free form cholesterol contents in the serum were increased caused by the alternating diets which was fed on 0.5, 1.0 and 3.0% defatted ginseng diet for 4 and 8 weeks after being fed on stock diet for 8 and 4 weeks, conversely total cholesterol contents in the aorta were decreased by the same alternating diets. Free form cholesterol contents in the serum, liver and aorta of the group which was fed on 1.0% defatted ginseng diet 8 weeks after being fed on stock diet for 4 weeks were increased, but that of the group which was fed alternately on 3.0% defatted ginseng diet were decreased than the corresponding defatted ginseng control diet group.

The present study was carried out to investigate the effect of pine oil on the body weight and lipid levels of serum in rats fed high cholesterol diet and high fat diet, Body weight, weight of various organs, and feeding efficiency ratio were measured to study the effect of pine oil on obesty at 4 weeks after an oral administration, Total cholesterol, triglyceride, total lipid, HDL-cholesterol and LDL-cholesterol were also analysed to identify the ameliorating effect of pine oil on lipid metabolism in serum of same rats, The results were summerized as follows; 1. The increase in body weight and feeding efficiency ratio induced by choleserol diet was less in pine oil treated rats, Furthermore, decrease in weight of liver, kidney, spleen, testis, and epididymis were observed in pine oil treated rats. 2, Associated with the decrease in body weight, there was a concomitant reduction in serum levels of total cholesterol, triglyceride, and total lipid in rats fed high cholesterol diet and high fat diet. respectively, after an oral administration of pine oil. 3. Serum levels of LDL-cholesterol was significantly decrease after an oral administration of pine oil in rats fed high fat diet. These results suggest that pine oil can ameliorate obesity and lipid metabolism in serum.

This study was carried out to investigate the effect of Meristotheca papulosa on lipid concentration of serum and liver in rats fed high fat diet for 4 weeks. Experimental groups ere divided into normal group (5% corn oil), high fat diet group (5% corn oil+20% lard), high fat diet and 5% or 10% Meristotheca papulosa treated group. The weights of kidney, heart and tests were not significantly different among the group, but weight of liver was significantly decreased by supplement of Meristotheca papulosa (10%). The contents of serum total lipid, trigly-ceride, total cholesterol, free cholesterol, cholesterol ester and atherogenic index were decreased, while HDL-cholesterol was increased by Meristotheca papulosa supplementation compared to high fat diet group. Meristotheca papulosa supplement has obvious effects on lowering hepatic total lipid, triglyceride and total cholesterol. Our findings suggest that Meristotheca papulosa supplement can improve lipid metabolism in high fat fed rats.

Certain indigestible oligosaccharides may benefit gastrointestinal tract via fermentation and proliferation of desirable bacterial species. The purose of this study was to elucidate the effect of selected oligosaccharides, such as fructooligosaccharides(FOS), soybean oliosaccharides(SOE), and highly concentrated branched oligosaccharides(HiBOS), on fecal micorflora proliferation, lipid concentration, lipid peroxide formation and antioxidant enzymes acitivies in plasma and liver of the rats. Thirty two male Sprague-Dawley rats were randomly assigned to one of four treatments ; 1) control diet(AIN-93G diet); 2) control diet +5% FOS ; 3) control diet + 5% SOE ; 4) control diet + 5% HiBOS. The duration of the study was 4 weeks. Fecal bifidobacteria concentration were significantly higher (p<0.05) in the HiBOS group compared with the control after 4 weeks of dietary treatment. FOS and SOE groups also had higher fecal bifidobacteria levels than control, but statistical significance was not found. The concentration of plasma total lipid was decreased by oligosaccharide consumption, especially in HiBOS group(p<0.05). The concentration of plasma total triglyceride was significantly lower in all of the oligosaccharide containing groups compared with the control(p<0.05). The plasma total cholesterol concentration tended to be lower in the oligosaccharide consuming groups than control. The concentrations of hepatic total lipid, triglyceride and total cholesterol were not affected by consumption of oligosaccharides. Thiobarbituric acid reactive substance(TBARS) concentrations and antioxidant enzyme activities in plasma and liver were not affected much by experimental diets. There results suggest that dietary oligosaccharides may be beneficial for increasing intestinal bifidobacteria and lowering plasma lipid levels.

The study examined the effects of dietary green tea powder supplementation on blood glucose, and plasma and liver lipid concentrations in diabetic rats. Twenty-five male Sprague-Dawley rats (body weight $200{\pm}5\;g$) were divided into two groups (diabetic and non-diabetic), which were each randomly divided into two subgroups that were fed a control and 1% green tea powder-supplemented diet. Serum and liver lipid concentrations were measured by established techniques. Low density lipoprotein-cholesterol (LDL-C) was calculated from an established equation. Body weight gain and feed efficiency ratio were lower in diabetic rats than in non-diabetic rats regardless of diet. There were no differences in weight gain in diabetic and non-diabetic rats consuming the control and green tea powder-supplemented diets. The levels of fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index of diabetic rats were significantly higher than that of non-diabetic rats. Conversely, the levels of high density lipoprotein-cholesterol (HDL-C) of diabetic rats was significantly lower than that of non-diabetic rats. Fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index were significantly lower in diabetic rats fed the green tea powder diet than in rats fed the control diet, and HDL-C was significantly higher in rats fed the green tea powder diet than in rats fed the control diet. The content of liver total cholesterol and triglyceride of diabetic rats were significantly higher than that of non-diabetic rats. Liver total cholesterol and triglyceride were significantly lower in diabetic rats fed green tea powder-supplemented diet than in rats fed the control diet. It is concluded that green tea powder supplementation positively influences blood glucose and lipid metabolism in diabetic rats. The present study, although not directly applicable to humans, may have some implications for individuals who habitually consume green tea powder.

This study investigated the effects of polymannuronate feeding on cholesterol levels of serum, liter tissue, and feces in rats. After one week of general diet feeding, four week old S.D. rats were fed basal group, cholesterol diet group (1$\%$ cholesterol), and rolymannuronate diet group (1$\%$ cholesterol,5$\%$ polymannuronate). The total cholesterol levels in the serum and liver tissue was significantly decreased in the polymannuronate diet group. The polymannuronate diet group showed increased amounts of feces, total fecal bile acid and dietary fiber contents compared to basal diet group and cholesterol diet groups. Also, the histology of liver showed serious localized fat drops in the cholesterol diet group, but the polymannuronate diet group showed fewer localized fat drops. These results suggest that feeding of polymannuronate improves the lipid metabolism profile of rats by changing the serum and liver tissue cholesterol levels with increased level of the total bile acid, total dietary fiber and total cholesterol level in the feces.

Objectives : This experimental study was designed to investigate the effect of SBY-III extract on the weight, cell size of epididymal fat-pad, fat accumulation area in liver, serum lipid level and UCP1 mRNA in brown adipose tissue of high fat diet-fed obese rats continued by high fat diet and regulated by normal Diet. Methods : The body weight gain, weight of the internal organs(epididymis, liver, brown adipose tissue), insulin, triglyceride, total cholesterol, total lopod, free fatty acid, expression of UCP1 mRNA were measured in high fat diet-fed obese rats continued by high fat diet and regulated by normal diet. The experimental study are divided into exp-I and exp-II. Each study was administered normal diet, high fat diet and SBY-III according to each situation. Normal group is normal diet for 8 weeks. Exp-I are divided into control group(high fat diet for 8 weeks) and sample group(high fat diet for 8 weeks and SBY-III for last 2 weeks). Exp-II are divided into control group(high fat diet for 6 weeks and normal diet for 2 weeks) and sample group(high fat diet for 6 weeks and normal diet with SBY-III for 2 weeks). These were then compared mutually. Results : 1. Irrespective of diet control, sample group taken SBY-III showed the more effective decrease of weight gain than control group and diet control-fed sample group with SBY-III showed the more effective decrease of weight loss including weight gain than control group. 2. Irrespective of diet control, sample group taken SBY-III showed the more effective decrease cell size of epididymal fat-pad, fat accumulation area in liver than control group. 3. Non diet control-fed sample group taken SBY-III showed the more effective decrease of serum triglyceride, total lipid, free fatty acid than control group and diet control-fed sample group taken SBY-III showed the decrease of serum triglyceride, free fatty acid than control group. 4. Only diet control-fed sample group taken SBY-III showed the decrease of UCP1 volume. Conclusions : These results shows that SBY-III has effects on anti-obesity, especially keeping pace with diet control.

Purpose: The purpose of this study was to compare the antioxidant level, serum cholesterol and skin ${\beta}$-carotene, of female elderly who had been living more then 10 months in institutions which offered either vegetarian or non vegetarian diet. Methods: Total of 110 female elderly, 56 from institution serving vegetarian diet and 54 from nonvegetarian diet, were recruited from institutions located in S and N city in Korea. ${\beta}$-carotene level was measured on their palm using Pharmanex Biophotonic Scanner and annual health evaluation data was utilized for the analysis of serum cholesterol. Results: The subjects on a vegetarian diet had a significantly higher level of phosphorus, carotene, and folic acid. The elderly who were living in an institution offering a vegetarian diet had a lower level of serum cholesterol and higher level of skin ${\beta}$-carotene, compared to those living in an institution offering a non-vegetarian diet. Conclusion: This study reveals that a vegetarian diet is beneficial in increasing skin ${\beta}$-carotene level, decreasing serum total cholesterol level. The skin ${\beta}$-carotene measurement appear valuable as a bio-marker of antioxidant intake. Further study on antioxidant food and effective serving strategy for elderly are recommended.

Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.
