摘要: 目的 探讨坎地沙坦对动脉粥样硬化大鼠血管形态的影响。 方法 通过给正常大鼠饲喂高脂饲料,建立动脉粥样硬化模型。将 50 只大鼠随机分为正常组,模型组,坎地沙坦低、中、高剂量组。12 周后取相同部位主动脉分别进行固定、染色,在光镜及电镜下进行观察,并测量血管内膜、中膜厚度。 结果 模型组与正常组相比主动脉出现动脉粥样硬化的形态学改变;与模型组相比坎地沙坦低、中、高剂量组动脉粥样硬化的形态学改变有所减轻。模型组与正常组相比,内膜与中膜厚度显著增加(P<0.01);与模型组相比,坎地沙坦中、高剂量组可明显减轻动脉内膜及中膜厚度(P<0.01)。 结论 坎地沙坦可减轻大鼠动脉粥样硬化形态学改变,减少血管内膜、中膜的增生。

Abstract: Objective To investigate the effects of Candesartan on morphological change of the artery in atherosclerosis model rats. Methods Normal rats were fed with high lipid feedstuff to set up atherosclerosis rat model. Fifty rats were randomly divided into normal group, atherosclerosis model group, groups of low, medium and high dose of Candesartan. After 12 weeks, the arteries of the same place in rats of each group were determined and observed under light microscope and electron microscope. At the same time, we measured the intimal and medial thickness of vascular walls. Results Compared with normal group, morphological change of atherosclerosis in the arteries of model group had been observed. Compared with model group, morphological change of atherosclerosis which could be observed under microscope of the Candesartan group had decreased. In model group, compared with normal group, the intimal and medial thickness of vascular walls were significantly increased(P<0.01). Compared with model group, the intimal and medial thickness were significantly reduced(P<0.01). Conclusion Candesartan can influence the morphology of artery in atherosclerosis rats and reduce the hyperplasia in the intima and media of vascular walls.
