观察在低胆固醇摄入（８９ｇ基础饲料＋１１ｇ调和油）和高胆固醇摄入（８９ｇ基础饲料＋１１ｇ调和油＋１ｇ胆固醇）两种条件下调和油对大鼠血脂、血清和肝ＭＤＡ、血清和肝ＳＯＤ、膜流动性等指标的影响。结果表明，低胆固醇摄入条件下，１∶１∶１５组血清ＴＣ、ＬＤＬＣ、ＭＤＡ极显著降低（Ｐ＜００１），血清ＳＯＤ活力极显著升高（Ｐ＜００１），膜流动性显著升高（Ｐ＜００５）；１∶１５∶１组血清ＳＯＤ活力、膜流动性显著升高（Ｐ＜００５）；１５∶１∶１组血清ＳＯＤ活力显著升高（Ｐ＜００５）。高胆固醇摄入条件下，１∶１∶１组血清ＴＣ显著降低（Ｐ＜００５）；１∶１∶１５组血清ＬＤＬＣ显著升高（Ｐ＜００５）；１∶１５∶１组和１５∶１∶１组血清ＴＣ和ＬＤＬＣ均极显著升高（Ｐ＜００１）。４个实验组的肝ＳＯＤ活力均极显著降低（Ｐ＜００１）、血清ＳＯＤ活力和膜流动性均极显著升高（Ｐ＜００１）。
To observe the effect of oil on blood lipid, serum and liver MDA, serum and liver SOD in two conditions of low cholesterol intake (89g basal diet + 11g blend oil) and high cholesterol intake (89g basal diet + 11g blend oil + 1g cholesterol) Membrane fluidity and other indicators. The results showed that the levels of TC, LDL-C and MDA were significantly decreased (P <001) ), The membrane fluidity increased significantly (P <005); the activities of SOD and membrane fluidity increased significantly in 1: 15:1 group (P <005); in 15:1:1 group Serum SOD activity was significantly increased (P <0 05). Serum TC was significantly lower in 1: 1: 1 group (P <005) under the conditions of high cholesterol intake; LDLC in serum was significantly higher in 1:1:15 group (P <005) 15:1 group and 15:1:1 group serum TC and LDLC were extremely significantly increased (P <001). The activities of SOD in the four experimental groups were significantly decreased (P <001), and the serum SOD activity and membrane fluidity were significantly increased (P <001).
