摘要:
A spacer (10, 10' , 10') disposed around a fastening piece (17) secured to a main fastening body (25a) , the spacer sandwiched between ahead (17b) of the fastening piece and a securing object (22) so that the spacer bears a securing force of the fastening piece to press the securing object. spacer includes a pair of arms (12, 13) made of a shape restoring material. Each arm has a fore end, and the fore ends are joined to each other with an adhesive material that is softened when heated. The arms expands radially such that the screw attachment is released from the head of the fastening piece when heat or force is applied to the arms.

The purpose of the present invention is to provide intervertebral disk nucleus pulposus stem cells or progenitor cells that may be used for treatment of intervertebral disk disorders. The present invention provides an intervertebral disk nucleus pulposus cell characterized by being isolated from the intervertebral disk nucleus pulposus of a vertebrate and being positive for at least one surface marker from among Tie2 and GD2. That is, the present invention provides an intervertebral disk nucleus pulposus stem cell characterized by being at least Tie2-positive for the surface marker and possessing self-renewal ability as well as multipotency capable of differentiating into adipocytes, osteocytes, chondrocytes and neurons. The present invention also provides an intervertebral disk nucleus pulposus progenitor cell characterized by being at least Tie2-negative and GD2-positive for the surface marker and capable of differentiating into any of adipocytes, osteocytes, chondrocytes and neurons.

It is an object of the present invention to provide a method and an apparatus capable of selectively damaging and killing tumor cells. In one aspect of the present invention, there is provided a method for selectively damaging and killing tumor cells comprising a step of irradiating tumor cells with a pulse light having continuous emission spectra ranging at least from 230 to 270 nm (UV pulse flash), outside a living body of a human or a living body of a non-human animal or in a living body of a non-human animal. The UV pulse flash, preferably, has an accumulated irradiation amount per unit area that is achieved at a distance of 8 cm from a light source having an integrated output of, for example, 90, 180-7100 or 14200 J. In other words, the UV pulse flash, preferably, has an accumulated irradiation amount per unit area of, for example, 6, 12-480 or 960 J/cm 2 in terms of an energy originated from a wavelength of UVC. The step of irradiating with the UV pulse flash is preferably carried out, for example, within 1 minute. The UV pulse flash is preferably emitted from a xenon flash lamp. As another aspect of the present invention, there is provided an apparatus for treating tumor tissues comprising a light source of the UV pulse flash.
