Abstract A method of and device for increasing the permeability of the skin of cellsf living beings, according to which the respective cells are introduced in the form of a suspension into an electrically conductive liquid. Thereby there is formed a physiological electrolyte solution which is passed into one of two chambers through a passage of a partition. This partition separates a container into these two chambers, each chamber having an electrode. This passage surrounds the focus of an electric field. The cells in the electrolyte solution are exposed to the electric field while passing from one chamber to the other chamber until macromolecules having a radius of at least 5 A are exchanged through the cell skin between the solution in the interior of the cells and the physiological electrolyte solution.
A method of increasing the permeability of the skin of cells of living beings, which includes in combination the steps of: introducing the respective cells in the form of a suspension into an electrically conductive liquid having a temperature of from 0° to 25° C and forming a physiological electrolyte solution, exposing the thus formed physiological electrolyte solution containing said cells to an electric field of predetermined strength until macromolecules having a radius of at least 5 A are exchanged through the skin acting as diaphragm for said cells between the solution in the interior of said cells and the physiological electrolyte solution.
