[Study of interaction of polystirolsulphonate with polymerization degree of 8 and polyallylamin with bilayer lipids membranes].

Interaction of polystirolsulphonate with polymerization degree of 8 (PSS-8) and polyallylamin PAA (molecular mass 60 kilodaltons) with viruses from bloodline of paramixo- and orthomixoviruses by the example of measles virus, parotitis and flu leads to the decreasing of infective activity. The possible mechanism of viral inhibitive action of these chemical compounds is damaging of interfacial antigenic proteins of paramixo- and orthomixoviruses. In this study it was detected the change of surface tension of bilayer lipid membrane in the presence of PSS-8 and PAA. The change of surface tension leads to disorder in viral proteins adsorption in bilayer lipid membrane. This process could lead to disorder of juncture and self-assembly of virions.
