Paper Abstract

The kinetics of aggregation and disaggregation of red blood cells in whole blood subjected to shear stress is different with normal and pathological blood. To measure the kinetics we have applied a backscattering nephelometric technique, and quantitatively registered the alternation of the scattered intensity due to appearance or disappearance of different types of cell aggregates under controlled shear stresses. The latter were obtained in a Couette flow in a thin gap between two concentrical cylinders, the inner one rotating at controlled velocities. The peculiarities of backscattered light signal formation and obtained results were discussed.
