Objectives : This study was designed to investigate the effect of water extract from Paeonia Lactiflora Pasll. with medicinal herb on plasma lipid and glucose in rats fed high fat diet. Methods : Experimental groups were divided into control diet group(C), high fat diet group(HF), high fat diet and 5% water extracts from Paeonia Lactiflora Pasll. with medicinal herb group(HFE I), high fat diet and 10% water extract from Paeonia Lactiflora Pasll. with medicinal herb group(HFE II). Weight gain, food intake, food efficiency, plasma lipid concentration and glucose were determined for 10 weeks during high fat diet. Results : In this experiment, body weight and food efficiency were significantly increase in high fat diet. High fat diet group showed elevated levels of total cholesterol, LDL-cholesterol and free fatty acid. Consumption of 10% water extract Paeonia Lactiflora Pasll. with medicinal herb lowers level of total cholesterol, LDL-cholesterol and free fatty acid. But levels of plasma triglyceride, HDL-cholesterol and glucose did not affect by high fat diet and water extract Paeonia Lactiflora Pasll. with medicinal herb Conclusions : In these results, water extract Paeonia Lactiflora Pasll. with medicinal herb in high fat diet group decreased plasma total cholesterol, LDL-cholesterol and free fatty acid. Thus the Paeonia Lactiflora Pasll. with medicinal herb might be useful in the treatment of hyperlipemia.

담즙산은 cholesterol의 대사산물로 체내에서 cholesterol을 제거하는 주경로로서, 체내 cholesterol 대사를 조절하는 중요한 수단이다. 최근에 복합담즙산 분해활력이 높은 L. acidophilus에 의한 혈중 cholesterol 저하효과에 관한 많은 연구들이 보고되고 있으며, 이것은 복합담즙산의 분해로 생성되는 유리 담즙산의 분 배출 증가와 장내 cholesterol 흡수에 필요한 복합 micelle 형성의 방해에 의한 것으로 알려져 있다. 즉, 유리 담즙산은 장내에서 복합담즙산보다 용해성이 낮아서 흡수되지 않고 분으로 배출되기 쉬워, 간에서는 분으로 배출된 양만큼의 부족한 복합담즙산을 보충하기 위해 cholesterol을 이용하여 새로운 복합담즙산을 생성하기 때문에 결국은 체내의 혈중 cholesterol 수준을 감소시키는 것으로 생각된다. 또한 담즙으로 분비되는 복합담즙산은 소장내에서 cholesterol의 용해 흡수에 도움을 주지만 유리 담즙산은 cholesterol 용해성이 낮기 때문에, 장내 cholesterol 흡수에 영향을 미치는 것으로 생각된다.

This study was carried out to investigate the effect of phytosterol ester addition on lowering blood cholesterol in cholesterol-reduced Cheddar cheese. For cholesterol removal, separated cream was treated with 10% ${\beta}$-cyclodextrin at 800 rpm, then blended with remaining skim milk and homogenized with 1,000 psi at $70^{\circ}C$. Experimental cheeses were manufactured by five different levels of phytosterol addition. After the cholesterol reduction process by ;${\beta}$-cyclodextrin, the cholesterol removal rate was in the range of 91.0 to 92.1%. Amount of short-chain free fatty acid and free amino acids increased with an increase of phytosterol ester, and those were significantly different from that of control in all ripening periods. All rheological properties also increased with an increase of phytosterol ester during ripening period. In sensory analysis, the scores of rancid, bitterness Cheddar flavor and off-flavor intensities increased significantly, while texture was decreased during ripening in phytosterol ester-added groups. Total blood cholesterol was reduced by 18% when rats were fed Cheddar cheese treated with 8% phytosterol. The present study indicated that phytosterol ester addition resulted in a profound lowering effect of blood with cholesterol-reduced Cheddar cheese.

(1) Control values of the hepatic lipids of mouse analysed by means of thin-layer chromatography were as follows: Total cholesterol $5.23{\pm}0.46\;mg/g$ Free cholesterol $4.29{\pm}1.23\;mg/g$ Esterified cholesterol $0.94{\pm}0.30\;mg/g$ Triglycerides $15.56{\pm}1.84\;mg/g$ Free fatty acids $1.26{\pm}0.56\;mg/g$ Phospholipids $29.84{\pm}6.11\;mg/g$ Total lipids $62.44{\pm}12.13\;mg/g$ (2) The garlic administration brought significant elevations in the hepatic contents of free and esterified cholesterds, triglycerides, free fatty acids, and phospholipids in the mouse, when it was injected in excess (2%, 10% suspension) intraperitoneally. (3) The total hepatic lipids of mouse were increased in corelation with the amount of the garlic administered to the animals. (4) A brief discussion was made on the results obtained.

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 investigate the anti-oxidant effect of Wasabia japonica(WJ). The anti-oxidant activities of various extracts from WJ were investigated. The water and ethanol extracts of WJ leaf were found to cause significant free radical scavenging effects on DPPH and nitric oxide(NO). Sprague-Dawley male rats were randomly assigned to one normal diet and three high cholesterol diet groups which contained 1%(w/w) cholesterol. After 4weeks cholesterol diet, the groups of high cholesterol diet were classified to control(normal diet only), WJR5(normal diet and 5% WJ root) and WJL5(normal diet and 5% WJ leaf). Liver xanthine oxidase(XO) activity in the rats of high cholesterol diet was decreased up to the levels of normal diet group according to WJ diet. The results indicated that WJ possesses antioxidant effects through free radical scavenging effects on DPPH, NO and the decreasing of XO activity. In view of these results, WJ is expected to be an effective material for the anti-oxidant.

The present study tested to recommend optimum level of Gastrodia rhizoma and effect on the compositional changes of the lipids in Sprague Bawley rats which were fed control diet adding 5, 10, 15% Dioscorea batatas powder and 5, 10, 15% Gastrodia rhizoma powder for 3 weeks, respectively The contents of moisture. ash, fat, protein and carbohydrate in dried Gastrodia rhizoma were 5.9, 2.7 2.1, 0.9 and 88.4%(w/w) respectively. Concentrations of total cholesterol and free cholesterol in liver were the lowest in the 10% Gastrodia rhizoma group. Concentrations of triglyceride and phospholipid in liver were lower in the 10 and 15% Gastrodia rhizoma groups than in the other groups. Concentrations of total cholesterol, free cholesterol, triglyceride and phospholipid in brain were significantly lower in the group 6, 7 compared to the other groups. Concentrations of triglyceride and phospholipid in kidney were slightly lower in the Gastrodia rhizoma groups than those in the Dioscorea batatas groups.
