摘　　要：以含１１％猪油、茶油、棉油、棕桐油及调和油的高胆固醇饲料分别饲养大鼠。发现：（１）棕桐油组血清总胆固醇（Ｔｃ）及ＬＤＬ－ｃ最低，猪油组最高，茶油组次之，ＨＤＬ－ｃ以棉油组最高，调和油组次之，猪油组及棕桐油组最低。ＨＤＬ－Ｃ／Ｔｃ也以棉油组最高，猪油组及茶油组最低。ＴＧ以猪油组及茶油组较高。（２）血清丙二醛以棕桐油组最低，猪油组最高。（３）棉油组的血清超氧化物歧化酶（ＳＯＤ）活力及肝ＳＯＤ活力较高。（４）棕榈油组及调和油组的血小板聚集率较低。（５）调和油组及棉油组的血栓素Ｂ２／６－酮前列腺素Ｆ１α比值较低。（６）茶油组及棉油组的红细胞变形能力较大。茶油组的红细胞膜流动性最好。Rats were fed with high cholesterol diet containing 11% lard(L), teaseed oil(TO), cotton-seed oil (CO),palm oil(PO) and blend oil(BO). It was found that:(1)the serum TC and LDL-C of rats fed with PO was the lowest, L was the highest,then TO. For serum HDL-C,CO was the highest,then BO,L and PO were the lowest.For HDL-C/TC,CO still was the hoghest,L and TO were the lowest.For serum TG;L and TO were higher than the other groups.(2)For serum MDA,the lowest was PO, the highest was L. (3)For platelet aggregation,PO and BO were lower,(5)For TXB2/6-K-PGF10 BO and CO were lower.(6)For erytherocyte in rats deformability,TO and CO were highet. For erytherocyte in rats membrane fiuidity,TO was the best.
