正加速度能使喂饲胆固醇家兔的血清总胆固醇含量升高得更多(P<0.01)。但主动脉弓内膜粥样斑面积,两组相差不显著。对照组的胸主动脉内膜粥样斑面积大于腹主动脉,实验组则相反。实验组冠状动脉口形成粥样斑和脂肪肝的例数比对照组多,相差显著(P<0.05)。 Positive acceleration increased serum total cholesterol levels in cholesterol-fed rabbits (P <0.01). However, aortic arch endocardial atherosclerotic plaque area, the difference was not significant between the two groups. In the control group, the area of ​​the atheroma in the thoracic aorta was larger than that in the abdominal aorta, while the experimental group was the opposite. The incidence of atherosclerotic plaque and fatty liver in the experimental group was more than that in the control group (P <0.05).
