[Electrophysiologic parameters of ion transport systems in early developmental stages of fish and amphibia].

Abstract

It is shown that the membrane potential level, ionic current and membrane conductance depend on the cell cycle stage both in Misgurnus fossilis L. embryos and in Xenopus laevis Daudin embryos by the microelectrode technics. Allowing for the role of the adenylate cyclase system in the membrane potential oscillations and ion conductance of membranes, some series of experiments for analysis of the inhibitor have been carried out.
