Study of rheological and electrical behaviour of RBC suspensions in dextran and PEG under non-steady flow. Role of RBC deformability and morphology
Original language description
The electrical conductivity and shear rate dependences in parallel with the rheological properties of the samples were studied under transient flow regimes at different local structure of the uniform Couette flow. Red blood cells (RBC) were treated withglutaraldehyde (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 RBCaggregation-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.
