本文建立了大鼠脑缺血及再灌注模型 ,并对缺血以及缺血后再灌注不同时间的血液触变性进行了实验研究 ,用 Huang’s方程拟合实验曲线以得到各组血液的 5个触变性参数。结果表明 :缺血以及缺血后再灌注不同时间 ,对血液触变性参数有明显的影响。缺血过程中 ,τ0 和 μ的值随着缺血时间的增加逐渐降低 ,缺血再灌注 1小时的 τ0 和 μ明显大于缺血期的值 ,τ0 也高于正常值 ,随着再灌注时间的增加 ,τ0 逐渐回落至正常血液水平 ,同时 μ也逐渐降低 In this paper, we established a model of cerebral ischemia and reperfusion in rats and studied the thrombosis of blood at different time after ischemia and reperfusion. Using Huang’s equation to fit the experimental curve to get the blood contact of 5 groups Denaturation parameters. The results showed that ischemia and ischemic reperfusion at different times, the blood thixotropic parameters have a significant impact. During ischemia, the values ​​of τ0 and μ gradually decreased with the increase of ischemic time. The values ​​of τ0 and μ at 1 hour after ischemia-reperfusion were significantly higher than those at ischemia, and τ0 was also higher than normal. With the reperfusion time Τ0 gradually dropped back to normal blood levels, meanwhile, μ gradually decreased
