Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

Abstract: A light source module with two wavelengths that is adapted to generate laser beams different in wavelength. In the light source module, a hologram optical element (HOE) is used to allow a first laser beam generated at a first light source and a second laser beam generated at a second light source to progress along same path. The HOE diffracts the second laser beam to change a progressive path of the second laser beam into that of the first laser beam. The first light source generates the first laser beam having a different wavelength from the second laser beam generated at the second light source.

Abstract: A different wavelength type of optical source module which generates light beams different in wavelength. In the optical source module, laser diodes are provided to be opposed to each of reflective films which is arranged to make a shape of a mountain. These respective laser diodes generates laser light beams different in wavelength. The light beams generated at the laser diodes are reflected by the reflective films at a right angle to progress along the same path.

Abstract: An annular shutter mirror which can selectively shut off a part of light beams progressing toward a target in the progressing direction thereof. The annular shutter mirror utilizes a fixed reflection face to reflect an incident light beam at a constant angle in accordance with an incident angle of the incident light beam. Around the periphery of the fixed reflection face, at least one flexible reflection face is formed in a shape of annular band. This at least one flexible reflection face selectively reflects an incident light beam at an angle different from a reflective angle of the fixed reflection area in accordance with an application condition of an electrical field.
