The present study was designed to observe the effects of soyprotein and casein with or without cholesterol on serum and liver lipids in male rats. The 6 experimental groups were as fellows ; SF ; soyprotein, cholesterol-free diet. SC ; soyprotein, 0.5% cholesterol added diet. CF ; casein, cholesterol-free diet CC ; casein,0.5% cholesterol added diet. SCF ; protein mixture of soyprotein and casein(1 : 1), cholesterol-free diet SCC ; mixed protein, 0.5% cholesterol added diet. The hypocholesterolemic and hypotriglyceridemic effects of soyprotein were observed at 3 weeks, but these effects disappeared at 6 weeks. The hypocholesterolemic effect of soyprotein was more obvious when the 0.5% cholesterol was supplemented in the diets. The serum free cholesterol level was not affected by the dietary protein source or the dietary cholesterol, therefore, the difference in serum total cholesterol among groups seems due to the difference in cholesterol esters. There was a tendency of a higher percentage of HDL in soyprotein groups compared to casein groups at 1 week, however, this tendency disappeared with time. The liver cholesterol and triglyceride contents were not differ among cholesterol-free diet groups, however, with addition of cholesterol, those of soyprotein groups were significantly lower than casein groups. The higher serum arginine/lysine ratio of soyprotein groups may offer the part of explanation of its hypocholesterolemic effect.

A nutrition survey regarding daily kimchi consumption and its hypolipidemic effect were carried out with 102 of healthy Korean adult men aged between 40 to 64 years old who visited hospital for physical examination. The physical and biochemical parameters of blood were examined as well as food record, preferences for taste, personal life habit, and family history of disease. Data were expressed as quartile according to kimchi consumption. The average daily kimchi consumption for 1st, 2nd, 3rd, and 4th per centile group were 68, 118, 208, and 383g, respectively. The intakes of dietary fiber and Ca were found to be increased as kimchi intake increased(p<0.05). The kimchi consumption level was selected as the determining factor for HDL C level analyzed by stepwise multiple regression(p=0.09). When correlation coefficient between kimchi consumption and other parameters were analyzed, kimchi consumption was positively correlated with HDL C and negatively correlated with LDL C(p<0.05). The preference for hot taste was negatively correlated with systolic blood presure. It seems that kimchi consumption is beneficial to elevate HDL C and lower LDL C level.

해조류인 참도박으로 부터 고지혈증 개선효과를 관찰하기 위하여 고지혈증을 유발시킨 흰쥐에 메탄올 추출물을 투여하고 혈액 및 간조직에서의 지방 함량을 측정하였다. 그 결과 참도박의 메탄올 추출물의 투여는 지방조직의 무게는 정상군에는 미치지 않으나 대조군에 비해 다소 감소하는 경향을 보였다. 고지방식이로 인위적으로 고지혈증을 유발시켰을때 정상군보다 total cholesterol, LDL-cholestero의 함량이 증가되던 것이 추출물의 투여로 total cholesterol의 함량이 현저히 감소되었으나 LDL-cholesterolt의 함량은 별다른 영향이 없었다. 또한 이들의 고지방식이군 보다 total lipid, triglyceride의 함량도 감소시켰다.

The effects of indigestible dextrin on lipids in serum, tissue, and feces were investigated in two experiments carried out with 64 male Sprague-Dawley rats for eight weeks. Experiment I diet(normal fat diet) containing 5% corn oil and experiment II diet(high fat diet) containing 18% fat(13% beef tallow and 5% corn oil) and 1% cholesterol were divided into four groups with 0.5% cellulose(0.5CL : control), 10% cellulose(10CL), 10% Indigestible dextrin I(ID-I) and 10% indigestible dextrin II(ID-II), respectively. ID-I and ID-II diets produced a decrease in serum total lipid and cholesterol concentrations in both normal and high fat diets but more significantly in the groups fed high fat diet. ID-I, ID-II, and 10CL of high fat diet decreased serum glucose concentration. ID-I and ID-II diets also decreased liver cholesterol and triglyceride concentrations in rats fed normal and high fit diets. The fecal excretion of cholesterol in ID-II/high fat diet was significantly higher than that of 0.5CL diet. Bile acid excretion was increased in the rats fed 10CL and ID-II diets of normal and high fat diets. These observations indicat the hypolipidemic and hypocholesterolemic effects of indigestible dextrin on the rats. These effects are mediated by the increase of facal cholesterol and bile acid excretion. (Korean J Nutrition31(6) : 981-990, 1998)

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.

Objectives : This study was aimed to investigate the effects of GamiSamgieum (SGMX) on hyperlipidemia using an animal model. Additionally, the underlying mechanisms were investigated by determination of gene expressions related with lipid metabolism. Methods : Forty mice were selected for use in this experiment, and then divided into five groups; Naive, Induced, SGMX 100, SGMX 200, and Lovastatin group as positive control with 8 mice each, and their blood was collected for analysis of blood and serum parameters. Results : Administration of SGMX significantly inhibited the increase of liver weight and the macrovacuolar cytoplasmic alterations in histopathologic finding. SGMX administration significantly protected the liver from pathologic elevation of AST and ALT and from lipid peroxidation. SGMX administration significantly lowered total cholesterol levels and TG, and partially upregulated the gene expression of LCAT, CYP7A1 and LDL-R receptor. Conclusion : SGMX is suggested to possess hypolipidemic effect, and thus could be a potential candidate for herbal hypolipidemic via further studies.

This study was performed to observe how soy protein and calcium in rats fed unsaturated fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues male Sprague-Dawley rats weighing approximately 220g were fed four purified diets which contained 18% (w/w) corn oil, 1% (w/w) cholesterol, two sources of protein : casein or isolated soy protein (ISP) and two levels of dietary calcium : 0.1% or 1.0%, first for four weeks (Expt. 1) and second for eight weeks (Expt. 2). The contents of total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding, the serum lipid and cholesterol concentration was not significantly different among the groups. After eight weeks feeding, these concentrations were significantly lower in ISP-High calcium group. The serum lipid concentration was influenced by dietary protein sources and calcium levels. These results indicated that the hypolipidemic effects of soy protein and high calcium intake were partly due to decrease in lipid absorption and these effects were not detected at 4 weeks feeding but 8 weeks feeding.

Hypolipidemic effect of Insamsansa-eum (ISE, Ren-Shen-Shan-Zah-Yin in Chinese) consisted of Red ginseng (RG; the steamed root of Panax ginseng C.A. Meyer) and Crataegii fructus (CF, the fruit of Crataegus pinnatifida BGE) is used frequently in China and Korea as a herbal medicine to treat arteriosclerosis, was investigated. Treatment of ISE significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels in Triton WR-1339-induced hyperlipidemic mice and serum TG levels in corn oil-induced hypertriglyceridemic mice. ISE significantly lowered the high blood TG and TC levels as well as body and epididymal mass weights in hyperlipidemic mice induced by long-term feeding of a high-fat diet and increased blood HDL cholesterol level. ISE and its ingredients, RG and CF, inhibited pancreatic lipase and HMG-CoA reductase activities. Of its ingredients, RG reduced the blood TC level and HMG-CoA reductase activity more than CF. CF reduced blood TG level and pancreatic lipase activity more than RG. These finding suggest that the antihyperlipidemic effect of ISE may be due to synergistic inhibition of HMG-CoA reductase and pancreatic lipase by RG and CF, and that ISE may be effective hypolipidemic agents.
