Red blood cells (RBC) were treated with glutaraldehyde (GA) with different concentrations (from 0,01% to 1%). A time course of conductivity of normal RBC and treated with GA suspended in dextran 70 was recorded under trapezoid change of shear rates. It provides experimental description of RBC aggregation-disaggregation processes and other cell-cell interactions. Dextrans induce morphological alterations in RBC shape and arrangement in the suspensions. Echinocytes are observed at low Dx 70 concentrations while spherocytes are found mainly in smears at higher Dx 70 concentrations. Their morphological characteristics affect blood electrical and mechanical properties. Pracoviště Ústav pro hydrodynamiku Kontakt Soňa Hnilicová, hnilicova@ih.cas.cz, Tel.: 233 109 003 Rok sběru 2011
