摘要 目的研究自发性高血压大鼠(SHR)的血压、内皮功能、纤溶活性的昼夜节律变化及厄贝沙坦的干预作用。方法 30只SHR大鼠分别于3 am、9 am、3 pm、9 pm测量血压,硝酸还原酶法测定一氧化氮(NO)、一氧化氮合酶(NOS),发色底物法测定蛋白C(PC)、组织型纤溶酶原激活剂(t-PA)、纤溶酶原激活物抑制剂-1(PAI-1)活性。喂食厄贝沙坦4周后复查上述指标。结果所有动物血压、心率、NO、NOS、纤溶活性均存在昼夜节律变化;采用厄贝沙坦干预后上述指标的昼夜节律无明显变化;同一时点血压、心率、PAI-1降低,NO、NOS、PC、t-PA升高(P均<0.01)。结论 SHR的血压、NO、NOS、纤溶活性存在昼夜节律变化;厄贝沙坦可降低SHR大鼠血压,改善内皮功能,调节纤溶活性,但对其昼夜节律无明显影响。
