[Prostaglandin regulation of ionic conductivity of model membranes].
Electrical conductivity of model membranes of lecithin, cardiolipin, gangliosides and lecithin-gangliosides mixture under the effect of PGE1, PGA1, PGI2 were investigated for a number of ions. Property of prostaglandins to increase membrane conductivity within a wide range of concentrations (10(-5) M--10(-10) M) was discovered. Cation selectivity of the membranes under the effect of prostaglandins was found. Ability of prostaglandins to change conformation of lipid membranes was indicated.
