n-3계 PUFA와 n-6계 PUFA의 배합비율을 달리한 혼합유지가 고지혈증 흰쥐의 지질개선 및 지방산 대사에 미치는 영향을 구명하기 위해 Sprague-Dawley계 숫흰쥐에게 돈지(3.0%), 버터(12.0%) 및 콜레스테롤(0.75%)를 첨가 조제한 식이를 3주간 급여하여 고지혈증을 유발시킨 후, 돈지 3.0%와 버터 12.0% 식이를 대조군으로 하고 아마인유와 해바라기종자유를 사용, 그 배합 비율을 달리한 혼합유지 및 항고지혈증 약제를 급여하여 2주간 실험사육한 후 간장의 지질성분 및 지방산 조성을 분석 검토한 결과, 간장의 총 콜레스테롤 및 인지질 농도는 대조군에 비해 2군(돈지 3.0%+올리브유 12.0%)에서 유의적으로 높은 반면 여타 실험군에서는 낮았으며 특히 3군(cholestyramine 2.0%)과 9군(돈지 3.0%+해바라기종자유 12.0%)에서 더욱 낮았다. 중성지질 농도는 대조군에 비해 4군(liparoid)을 제외한 여타 실험군에서 유의적으로 낮았으며 특히 9군에서 현저히 낮았다. 간장지질의 지방산 조성에서 각 성분 모두 C_(18:2)의 함유비율이 높았으며, n-6계 PUFA의 함유비율은 5군(linseed oil 12.0%)에서 9군으로 감에 따라 증가되는 반면 n-3계 PUFA는 감소되는 경향으로 대체로 시험유지의 지방산 조성이 반영된 것으로 나타났다. 이상의 결과에서 간장의 총 콜레스테롤, 인지질 및 중성지질 함량 등으로 미루어 보아, 간장지질 개선효과는 돈지 3.0%와 해바라기 종자유 12.0%를 급여하였을 때 가장 높았으며, 간장지질의 지방산 조성은 대체로 시험유지의 지방산조성에 영향을 받은 것으로 나타났다. This study was carried out to investigate the effect of the feeding mixture of linseed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hyperlipidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter, and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic drugs for 2 weeks. Analysis of the lipid component and the fatty acid composition of the liver showed following results. Concentrations of total cholestrol and phospholipid in liver were significantly higher in group 2(olive oil 12.0%) and lower in the other groups than in the control group, especially lower in groups 3(cholestyramine 2.0%) and 9(sunflower seed oil 12.0%). Concentration of triglyceride was lower in the other groups except group 4(liparoid), especially lower in group 9 than in the control group. In the fatty acid composition of liver lipids, C_(18:2) was the major fatty acid. Contents of n-6 PUFA increased, while those of n-3 PUFA decreased in groups 5(linseed oil 12.0%) to 9 as n-3P / n-6P ratio of the test lipid decreased and were affected by the fatty acid composition of the test lipids. From the data on concentrations of total cholesterol. Phospholipid and triglyceride in liver, we concluded that the feeding mixed with 3.0% lard and 12.0% sunflower seed oil were most effective for the improvement of the liver lipids. The fatty acid composition in liver lipids were affected by the fatty acid composition of the test lipids.

This study was designed to observe the effects of the feeding Platycodon gradiflorum, Codonopsis lanceolala, perilla oil and safflower oil on the improvement of the lipids in the serum and liver of dietary hypercholesterolemic rats. Experimental groups mixed with 5% cellulose+10% lard (group 1, control group), 2% cholestyramine+10% lard (group 2), 5% C. /anceo/ata+10% perilla oil (group3). 5% P. grandiflorum+10% perilla oil (group 4), 5% C. /anceolata+ 10% safflower oil(group 5) and 5% P. grandiflorum+ 10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. Concentrations of total cholesterol in serum were significantly lower in the all experimental groups (2~6 groups) than in the control group, and particularly, the lowest in the group 2 and 6. Concentrations of HDL-cholesterol in serum were remarkably higher in the groups 2 and 4. The ratio of HDL-cholesterol to total cholesterol was the highest in the group 2. Atherosclerotic index was lower in the groups 2, 4 and 6. Concentrations of LDL, phospholipid and triglyceride in serum were remarkably lower in the all experimental groups than in the control group, and particularly, lower in the groups 2, 4 and 6. Concentrations of free cholesterol and cholesteryl ester in serum were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in the group 2. Concentrations of glucose in blood were the lowest in the group 2. And groups 3 and 5 were significantly lower. Contents of total cholesterol and triglyceride in liver were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in the groups 2 and 3. Phospholipid content was showed little difference among groups but the lowest in the group 2. From the above research, the feeding 5% Platycodon grandiflorum+10% perilla oil and 5% Platycodon grandiflorum+10% safflower oil were effective on the improvement of the lipid compositions in serum and liver.

This study was designed to observe the effects of feeding dietary fiber on the improvement of the fatty acid metabolism in brain, heart and lung in dietary hypercholesterolemic rats. Experimental groups with 5% level of cellulose(A group as control group), chinese cabbage root(B group),tora stalk (C group)and sweet potato stalk (D group)were adminstered to the male rats of the Sprague-Dawley for 4 weeks. The results obtaind are as follows. In the fatty acid composition of total lipid, phospholipid in the brain, the docosahexaenoic acid in the PUFA was major fatty acid. In the fatty acid composition of total lipid, phospholipid in the brain, the docosahexaenoic acid in the PUFA was major fatty acid. While in the fatty acid composition total lipid and phospholipid in the heart, the eicosapentaenoic acid in the PUFA was major fatty acid. And in the fatty acid composition of total lipid and phospholipid in the lung, the content of palmitic acid and oleic acid were higer than other fatty acid. These fats were influenced by the fatty acid composition of the test lipids. From the above result, the feeding of chinese root was effective on the improvement of the lipid compositions in principal organ tissue.
