Paper Abstract

The optical diffractometric method for the measurement of cellular deformability is described. It permits working in real time and enables measuring of an internal viscoelasticity of cells. Deformability of human erythrocytes as a function of applied fluid shear stress is analyzed. It is shown that some limit of proportionality exists below which the deformation of cells is proportional to the fluid shear stress value. But the cells deformability is nearly independent on the stress beyond this limit. Both blood of healthy adults and newborn infants was studied and obtained results are described. Drawbacks of the method are discussed and an improved measuring system is proposed.
