[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.

[The effect of the quaternary ammonium salt of conidine oligomer-25 (QAS CO-25) on the activity of prothrombin complex factors].

Quaternary ammonium salt of oligomer-25 conidine (QAS O-25C) was used for regulation of hypocoagulation effect of Syncumar--anticoagulant of indirect type of action. The experiments were carried out on male rats. Experimental methods included thromboelastography, determination of thromboplastin time (after Quick) and determination of activity of single coagulation factors.
