The effect of synthetic polycation of the quarternary ammonium salts of polymetacryoil lupinin on the ionic permeability of erythrocyte membrane

: It is shown that synthetic polycation quarternary ammonium salt polymetacryloil lupinine (poly-MACL) effects on passive ion permeability of erythrocytes membranes. The amplitude of Cl-/OH- exchange decreased in the buffer with SDS-polycation complex and simultaneously with pH elevation K+ exflux increased. On the contrary, in presence of heparin co-effect of poly-MACL and SDS vanished. Thus, synthetic polycation in the complex with long-chain anion (SDS) injure the membranes and effect depends on lipophilic-hydrophilic balance of polycation-SDS complex.
