Abstract: The object is to provide a carrier showing superior adhesion property and detachability, which is suitable for transferring a cell sheet. A carrier for transferring a cell sheet for transplantation comprising a cell sheet-adhesive coating layer that can respond to a non-cytotoxic condition and a support layer consisting of a base material acceptable as a medical material is provided. By applying a cell sheet adhering to the coating layer of the carrier to a transplantation site and providing the non-cytotoxic condition, the carrier can be detached and removed with maintaining the cell sheet at the transplantation site.

Abstract: To avoid a reduction of the conductivity in iontophoresis due to the electrical decomposition and the changes in chemical properties of the electrodes themselves, covering by an electrical insulator, and to prevent a drop in the transport rate due to ions freed from the electrode. Provision is made of an electrode structure provided integrally with a reversible electrode and an auxiliary electrode for regeneration of the same and a regeneration current conducting means for conducting a current for regeneration of the reversible electrode when the therapeutic current is off, or the invention is comprised of a reversible electrode and an ion exchange membrane difficult for ions freed from that electrode to penetrate.

Abstract: A printed electrode for biological use comprises a support having thereon a printed ink paste or binder containing (a) a microgranule of at least one hydrophilic substance selected from the group consisting of hydrophilic polymers and water-soluble substances and (b) a microgranule of an electroconductive substance.
