生物大分子对电流场中红细胞沉降行为的影响

The Influence of Macromolecules on Erythrocyte Sedimentation Behavior in Electric Field

利用自行研制的红细胞电场沉降实验系统，研究了竖直向上的直流恒流电流作用下红细胞在分别含分子量７万的葡聚糖及分子量５万的聚赖氨酸的生理盐水溶液中的沉降行为，得出红细胞在该电流作用下的沉降与这两种分子的电荷特性及质量浓度有关，在质量浓度６×１０－２ｇ／ｍＬ，分子量７万的葡聚糖生理盐水溶液中红细胞的聚集速度由于电流的作用显著加快。

In this paper,the relationship between erythrocyte sedimentation behavior and the type of macromolecules in suspension medium in an upward DC electric field of constant current is investigated.The results show:a) Erythrocyte sedimentation behavior is dependent on the electric characteristic and concentration of macromolecules:b) In Dextran 70 6×10 -2 g/mL saline solution,erythrocytes aggregate more quickly in this type of eletric field.
