Abstract

The diffusion coefficient of erythrocytes was measured using quasi-elastic light-scattering (QELS) techniques. The cells were suspended in phosphate-buffered saline solutions with and without a macromolecule, polyvinylpyrrolidone (PVP[360]). In the presence of the PVP(360) an anomalously high diffusion coefficient was measured for metabolizing cells with a normal transmembrane potential. The results are in agreement with experiments on rouleau formation by red blood cells and are supportive of the hypothesis of a long-range coherent interaction between metabolically active biological cells.

摘要

使用准弹性光散射（QELS）技术测量红细胞的扩散系数。将细胞悬浮于含有和不含有大分子聚乙烯吡咯烷酮（PVP[360]）的磷酸盐缓冲盐溶液中。在PVP(360)存在的情况下，对于具有正常跨膜电位的代谢细胞，测量到异常高的扩散系数。这些结果与红细胞形成缗钱状的实验结果一致，并支持代谢活跃的生物细胞之间存在长程相干相互作用这一假说。
