The present study was carried out to develop cholesterol-reduced and gamma linolenic acid (GLA)-added butter and to examine the changes in chemical and sensory properties, and cholesterol lowering effect of GLA addition. The cholesterol removal rate reached 93.2% by $\beta$-cyclodextrin in butter before GLA addition. The thiobarbituric acid value of cholesterol-reduced and GLA-added butter increased slowly up to 4 week and plauteaued thereafter. TBA value was significantly increased with 2% GLA addition, compared with no GLA addition. The production of short-chain free fatty acids (FFA) increased with storage in all treatments. From 4 weeks storage, the amount of short-chain FFA in 2% GLA-added group was significantly higher than those in other groups. Among sensory characteristics, color, greasiness and overall acceptability were mostly affected by GLA addition, however, the rancidity value of 2% GLA addition was significantly different from those of control and GLA-unadded and cholesterol-reduced butter at 0, 6 and 8 week storage. Among groups, no difference was found in texture in all storage periods. The smallest increase of total blood cholesterol in rats was found in the group fed 2% GLA-added and cholesterol-reduced butter for 8 week, compared with that in controls. The present results showed the possibility of cholesterol-reduced and GLA-added butter development without much difference in chemical, rheological and sensory properties, and indicated a slow increase effect on blood total cholesterol in rats.

Objectives : The purpose of this study is to find out the effect of antioxidation related to aging of Cheongeumyeonsudan which is written on Dongui-bogam experimentally. Method : 14 weeks aged SD albino rats were separated into uncontrolled group, controlled group and CGY group. As controlled and CGY groups were induced aging by subcutaneous injection of D-galactose, at the same time we administered the extract of Cheongeumyeonsudan to CGY group for 6 weeks. After then we drew blood from each group, and took measurements; the activity of SOD, GSH-px, catalase in erythrocytes, TBARS value, concentration of total lipid, tryglycende, total cholesterol, HDL-cholesterol in blood plasma. Results : The activities of SOD, GSH-px in erythrocytes were significantly increased in the CGY group compared with control group. The activity of catalase showed a tendency to increase, but it was nor remarkable. The concentration of total lipid, the values of TBARS and total cholesterol was significantly decreased in the CGY group compared with control group, and the concentration of plasma HDL-cholesterol was not remarkable. The concentration of tryglycende in plasma showed a tendency to decreased. Conclusions : it is suggested that Cheongeumyeonsudan decreased the activities of free radical, the concentration of lipid in plasma and generate enzyme which form lipid peroxide.

The purpose of the present study was to investigate the effect of Korea leek on plasm lipids and platelet aggregation in hypercholesterolemic rats fed different dietary fat. Sprague-Dawley rats were fed with hyperlipidemic diet for 4 weeks in order to induce hyperlipidemia, followed by the feeding of experimental diets for additonal 4 weeks. We used three kinds of lipid(perilla oil, corn oil and lard). Korean leek of experimental diets was prepared by drying and milling. Powdered Cellulose and powdered Korean leek were added to experimental diets at the level of 5% (w/w). Serum concentrations of total lipid, total triglyceride, total cholesterol and LDL-cholesterol decreased in the order of perilla oil, corn oil and lard. Korean leek significantly decreased total lipid, total cholesterol, LDL-cholesterol, platelet count, prothrombin time, and platelet aggregation in rats fed a lard diet. The present observation indicates that Korean leek might be helpful for the prevention and threapy of hyperlipidemia and platelet aggregation.

The aim of this study is to investigate the effects of hot water soluble extract from Angelicae Radix on the components of serum and liver and the effects on the antioxidant system. For this purpose, five experimental groups were set up. And for fat source, perila oil enough with unsaturated fatty acid and beef tallow enough with saturated fatty acid were supplemented to the rats together with hot water soluble extract from Angelicae Radixs. Five experimental groups kept eight Sprague-Dawley rats respectively. They were CO group supplemented with basic diet of AIN-93, PO group supplemented with perila oil, POA group supplemented with perila oil and hot water soluble extract from Angelicae Radix, BT group supplemented with beef tallow, and BTA group supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The results were; 1) Final weight, weight gain, fluid intake and FER were not different significantly among the experimental groups, 2) Significant difference of food intake was observed(p<0.05) in BTA group only, 3) No significant difference was observed in serum total lipid, serum triglyceride and HDL cholesterol among experimental groups. Serum total cholesterol and LDL cholesterol were significantly low(p<0.05) in the group supplemented with beef tallow which was with hot water soluble extract from Angelicae Radix (BTA group). 4)Liver total cholesterol in liver was low in groups supplemented with perila oil and hot water soluble extract from Angelicae Radix. In summary, hot water soluble extract from Angelicae Radix did not affect the weight gain, fluid intake and food efficiency ratio among the experimental groups, but had an effect of lowering food intake, serum total cholesterol and serum LDL cholesterol significantly in the groups which were supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The effect of lowering liver total cholesterol with the supplementation of hot water soluble extract from AnRelicae Radix was observed in perila oil group only. The effect of lowering cholesterol with the supplementation of hot water soluble extract from Angelicae Radix was observed both in serum and in liver.

1. 수축기 혈압은 운동을 하고 있는 군에서 약간 낮았으나 이완기 혈압은 유의성 있는 차이를 보이지 않았다. 운동을 하고 있는 여대생의 경우 체지방량이 낮게 나타난 반면 제지방량은 변화가 없어 운동 여부에 의한 차이가 거의 보이지 않았다. 또 혈중 포도당 함량은 규칙적인 운동을 하고 있는 여대생에서 다소 높은 수준이었다. 2. 체지방율은 지속적인 운동을 하고 있는 여대생에 서 유의성은 없었지만 약간 낮았으며 혈청 총 콜레스테롤과 중성지방의 농도 역시 유의성 있게 낮게 나타났다. HDL 콜레스테롤 농도는 두 군 모두 거의 비슷한 수준으로 군간에 뚜렷한 차이를 보이지 않았던 반면 LDL 콜레스테롤의 경우 운동에 의해서 유의성 있게 낮게 나타났다. 따라서 규칙적인 운동에 의해서 HDL-Chol/Total-Chol 비율은 증가되었으며 LDL-Chol/HDL-Chol의 비율은 낮았다. 3. 혈액중 지단백질의 상대적인 분포는 HDL(%)의 경우 지속적인 운동을 하고 있는 여대생의 경우 일반 여대생에 비해 거의 차이가 없었고 LDL(%)는 유의성 있게 낮았던 반면 VLDL( %)는 오히려 높게 나타났다. Plasma의 지방산 조성중 포화 지방산 함량은 운동을 하고 있는 여대생에서 약간 높았지만 다가 불포화 지방산 함량은 같은 수준으로 두 군간에 차이를 보이지 않았다.

The effects of dietary Ca and Na levels on lipid metabolism in hyper lipidemic/hypercholesterolemic rats were examined. In Expt. 1, normal rats were divided into six groups and fed high fat(15%, w/w)/cholesterol(1%, w/w) diet containing two levels of Na, low (0.05) or high(1.5%) and three levels of Ca, low(0.1%), normal (0.5%), or high(1.5%) for 8 weeks. In Expt. 2, hyperlipidemia / hypercholesterolemia rats were induced by feeding high fat / cholesterol diet for 4 weeks. They were divided into four groups and fed the high fat / cholesterol diet, containing two levels of Na, low or high and two levels of Ca, low or high for 4 weeks. In Expt. 1, total lipid and total cholesterol contents in serum and liver were significantly lower in rats fed high Ca diet than in rats fed normal or low Ca diet regardless of dietary Na levels. Serum TG was the highest in rats fed low Ca and low Na diet. In Expt. 2, Serum total lipid, TG, and total cholesterol levels decreased by 24, 35, 26% respectively in rats fed high Ca diet regardless of dietary Na levels. Serum total lipid level tended to increased in rats fed low Na diet. The total lipid and TG contents in liver slightly decreased in rats fed high Ca diet. Another observation was that high Ca intake significantly faciliated the fecal lipid and cholesterol excretion regardless of dietary Na levels. There results suggest that the hypolipidemidc/hypocholesterolemic effects of high Ca diet could be partly due to increase in lipid and cholesterol excretion and these effects may be independent of dietary Na levels.
