title: [Tissue reaction with platinum-iridium insulated electrodes (author's transl)].
abstract: Pt-Ir-electrodes were coated with different insulations. Some of the insulations proved to be highly cytotoxic. Pt-Ir (9:1) electrodes coated with "PYRE-M.L." were easy to handle and did not show any cytotoxic effects. A change of electric impedance was found when the voltage was raised and platinum had changed the surface of the cathode.
