[Effect of falloidin on permeability of intercellular channels for inorganic ions and fluorescein]

It has been shown on larva gland that falloidin - a toxic of toadstool inducing an increased number of membrane microfilaments-affects the efficiency of intercellular transfer of small inorganic ions and molecules of organic dye fluorescein-Na. The data obtained are in favour of the participation of microfilaments in the regulation of intercellular diffusion communication.
