有氧运动和膳食脂肪对ApoE基因缺陷小鼠动脉粥样硬化斑块形成的影响

为了探讨有氧运动和膳食因素在动脉粥样硬化斑块形成过程中的作用，研究了在跑台上进行的有氧运动和低脂膳食对ApoE基因缺陷小鼠动脉粥样硬化斑块形成过程的影响。结果表明10周中等强度的有氧运动组和低脂膳食组ApoE基因缺陷小鼠主动脉窦处形成的动脉粥样硬化斑块面积均较对照组减少（P<0.05）；有氧运动结合低脂膳食组ApoE基因缺陷小鼠的斑块面积分别低于单独的运动组和低脂膳食组（P<0.05）。研究提示有氧运动和低脂膳食均有利于并有效减轻动脉粥样硬化斑块的形成，有氧运动和低脂膳食两种因素结合的作用大于单独的有氧运动和低脂膳食的作用，二者在预防动脉粥样硬化斑块的形成上可能存在协同加强作用。

Effect of Aerobic Exercise and Dietary Fat on the Formation of Atherosclerotic Plaque in ApoE-Deficient Mice

To approach the effects of aerobic exercise anddietary fat on the formation of atherosclerotic plaque, we have adopted the ApoE-gene knockout mice as the model to study the effects on an animal treadmill. The results show that the plaque area at the aortic sinuses of the exercised and low fat diet fed mice group were significantly reduced as comparing with the control group respectively. Mice of aerobic exercise and low fat diet combined treated group have the least lesion area of plaque as compared with the other groups. These results have indicated that either aerobic exercise or low fat diet is beneficial and effective to alleviate the formation of atherosclerotic lesions. However, aerobic combined with exercise can provide the greatest benefit in the alleviation of the formation of atherosclerotic plaque as compared with the single factor of either exercise or low fat diet.
