Abstract: The present invention provides a method for transplanting lymphohematopoietic cells into a mammal, which comprises the step of injecting cells into a bone marrow cavity, and wherein the cells have an exogenous gene encoding a receptor that induces cell proliferation in response to ligand binding. By combining intra-bone marrow transplantation (iBMT) and selective amplifier gene (SAG), marrow conditioning before the injection of the cells can be omitted. The present invention further provides a bone marrow transplant and a kit for transplanting lymphohematopoietic cells into mammals. Furthermore, the invention provides an SAG particularly suitable for such transplantation.

Abstract: A polarized relay includes a coil block having an elongated coil bobbin, a core inserted therein, and an excitation coil wound about the coil bobbin. The core has opposed pole ends projecting upwardly from longitudinal ends of the coil bobbin. A permanent magnet is interposed between the pole ends on the coil bobbin. Disposed on the coil block is an armature block which comprises an elongated generally flat armature and a set of movable springs carrying movable contacts. The movable springs are held together with the armature by means of an electrically insulating harness molded on the armature. The armature is pivotally supported on the coil block to be movable between two contact operating positions and constituting a magnetic circuit with the core and the permanent magnet for polarized operation of the armature.
