  • Publication number: 20050013791
    Abstract: A cytokine-inducing material and a cytokine-inducing instrument to be used in cytokine-induction therapy and the like. More specifically speaking, a cytokine-inducing material characterized by containing a water-insoluble induction potentiator comprising a cytokine-inducer such as BCG, a polymer, etc.; and a cytokine-inducing instrument having this inducing material packed in a container. By bringing the inducing material into contact with, for example, blood or blood components, cytokine can be induced more effectively than conventional cases.

  • Patent number: 6468734
    Abstract: An object is to obtain a container for measurement of cell functions which is simplified in operation, less risky and capable of measuring the cell functions very accurately. A container for measurement of cell functions, for use in the determination of a physiologically active substance produced by blood cells, is constituted such that an amount of material capable of inducing production of the physiologically active substance, when extracted by collecting water of a volume equal to a liquid volume to be subjected to measurement, is controlled at a level insufficient to induce production of the physiologically active substance from the blood cells.
