摘　　要：目的　探讨抵当汤改良方抗家兔实验性动脉粥样硬化效应及其可能机制。方法　运用图像分析法测定主动脉内膜脂质斑块面积百分比 ;脂代谢指标分别运用酶动力学法、一步法、免疫透射比浊法等方法测定 ;血浆超氧化物歧化酶与丙二醛分别运用微量快速测定法、改良的八木国夫法测定 ;用薄层色谱法进行神经酰胺含量测定。用TUNEL法检测主动脉脂质斑块部泡沫细胞凋亡数量。结果　抵当汤改良方能有效减轻主动脉脂质斑块面积 ,调节脂代谢紊乱 ,提高机体抗氧化酶活性 ,降低主动脉脂质斑块部神经酰胺含量及泡沫细胞凋亡数量。结论　抵当汤改良方具有较好的抗家兔实验性动脉粥样硬化效应 ,其作用机制与其调节脂代谢、抗氧化损伤、阻抑泡沫细胞的凋亡等有关。AIM To observe the effects of improved prescription of Didang-tang (IPDT) on exprimental atherosclerosis(AS) in rabbits and study the possible mechanism. METHODS Lipid plaque area of aortic endothelium was measured by image analysis method. lipid metabolism was measured by enzyme dynamics method, one-step method and immunization photoextinction. Plasma SOD and MDA was measured by microcontent fast detecting method and modified Ba MuGuoFu method. Ceramide was measured by thinlayer scannig; apoptosis of foam cell of aorta lipid plaque was measured by TUNEL method.RESULTS IPDT reduced lipid plaque area of aortic endothelium,regulated lipid metabolism, improved antioxidation of organism, ced ceramide content of aorta lipid plaque and apoptosis of foam cell.CONCLUSION IPDT has good effects of anti-exprimental AS,the possible mechanism maybe related to regulation of lipid metabolism and antioxidation and depression of apoptosis of foam cell.
