摘要
目的:研究血管紧张素转换酶抑制剂(ACEI)培哚普利和血管紧张素Ⅱ的Ⅰ型受体(AT1)拮抗剂洛沙坦对肿瘤坏死因子(TNF)α刺激的心肌细胞间粘附分子-1(ICAM-1)表达的影响。  方法:运用流式细胞仪观察培养的乳鼠心肌细胞ICAM-1的表达量。  结果:TNF-α可明显增加心肌细胞ICAM-1的表达量。从时间变化看,以刺激6 小时表达量最高,但随作用时间延长表达量减少。培哚普利(10- 6 m ol/L,10- 8 m ol/L)和洛沙坦(10- 6 m ol/L,10- 8 m ol/L)均可明显抑制TNF-α刺激的心肌细胞ICAM-1 的表达量。  结论:培哚普利和洛沙坦均可抑制培养的心肌细胞因子TNF-α诱导而上调的ICAM-1 的表达,这可能是ACEI和AT1受体拮抗剂治疗心力衰竭时的心脏保护效应的重要原因
