摘　　要：利用Low Shear—30流变测定仪对35例脑血栓形成、36例脑动脉硬化症患者及36例健康对照者作了低切变率下的全血粘度及复合粘度的弹性分量的测定。红细胞聚集性增加是二种脑血管疾病的共同变化,提示在急、慢性脑血管疾病中存在明显的血流变学异常。后者使脑血流量减少,产生低灌注,可促成脑缺血及血栓形成。作者强调利用血流变学参数预测中风尚不成熟。Using the Low Shear—30 Sinus Rheometer,We studied the changes of hemorheological parameters in patients with cerebral thrombosis(n=35)and atherosclerosis(n=36). There was a significant impairment of blood flow Caused by increasing of blood viscosity at low shear rate(η0.512)and elastic component(η”),which represonted more roulea- ux formatim.It Could therefore bc deduced that in ischemic Stroke the aggregate form- ation of erythrocytes as hemorheological parameter should be emphasijed.
