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.
结果表明,合成聚阳离子季铵盐聚甲基丙烯酰卢平宁(聚-MACL)对红细胞膜的被动离子通透性有影响。在含有SDS-聚阳离子复合物的缓冲液中,Cl⁻/OH⁻交换的幅度降低,同时随着pH值升高,K⁺外流增加。相反,在肝素存在的情况下,聚-MACL和SDS的协同作用消失。因此,与长链阴离子(SDS)形成复合物的合成聚阳离子会损伤膜,其作用取决于聚阳离子-SDS复合物的亲脂-亲水平衡。
