Abstract
Aggregation mechanism and deformability in pentoxifylline- and dispirin-treated erythrocytes are measured and compared with that of normal cells. The aggregation process is analyzed in terms of parameters which are obtained from the sequential recording of the transmitted light signal throughout the aggregate formation and sedimentation process. Erythrocyte deformability is determined by measurement of passage time through cellulose membrane. The variations in aggregation parameters in pentoxifylline-treated samples show that the formed aggregates are of larger size which sediment faster. In dispirin-treated cells, the formation of large size aggregates is delayed. The entire process is completed faster in pentoxifylline-treated compared to that of dispirin-treated cell whereas the normal sample shows an intermediate value. The deformability of erythrocytes treated with these drugs is increased.
