摘　　要：目的 :研究利用激光衍射法测量红细胞膜粘度。方法 :利用红细胞变形恢复过程 ,建立红细胞变形指数与红细胞膜粘度的关系。结果 :采用这一方法我们测量了 2 0个样本的红细胞膜粘度 ,得到其平均值为 6 .5 6× 10 - 4dyn.s/cm,与文献报道的采用微吸管技术所测得的结果相近 ,标准误差为 1.33× 10 - 5dyn.s/cm。结论 :测量结果验证了这种方法的可靠性 ,这种方法的优点在于易于操作 ,并且测量的结果可代表全体红细胞的平均结果 。Objective:To study measuring RBC membrane viscosity by using ektacytometry.Methods:We obtained the relationship between RBC deformation index and RBC membrane viscosity in the process of RBC deformation recovery.Results:With the methods we got,we measured the membrane viscosity of 20 samples of the RBC.The mean value was 6.56×10 4 dyn.s/cm.The value was consistent with the value measured by the method called micropipette aspiration technique.Conclusion:It was authenticated that this method is acceptable.And because the value by this way was mean value of the whole RBCs,its better than other way.
