Abstract: An electromagnetic wave sensor includes: a first wire which extends in a first direction; a second wire which extends in a second direction different from the first direction; and an electromagnetic wave detector which is electrically connected to the first wire and is electrically connected to the second wire, wherein the second wire is provided so as to leave an interval with respect to the first wire in a third direction orthogonal to the first direction and the second direction, and the second wire is disposed to three-dimensionally intersect the first wire. At least one wire of the first wire and the second wire includes a wide portion, which is wider than an average value of a width of a portion excluding an overlapping portion of the at least one wire, in the overlapping portion in which the first wire and the second wire overlap each other.

Abstract: A supplementary therapeutic agent for the treatment of immunodeficiency syndrome with reduced NK (natural killer) activity and an immunopotentiator preparation containing it are provided.A supplementary therapeutic agent for immunopotentiation which comprises L-cysteine, L-cystine, or L-glutamine, or salts thereof and is used in combination with an immunopotentiator such as lentinan, OK-432, sizofiran or the like, and an immunopotentiator preparation containing the agent. This combination of agents is useful as a supplementary therapeutic agent for the treatment of an immunodeficiency, such as low NK activity syndrome, chronic fatigue syndrome, acquired immunodeficiency syndrome, or congenital immunodeficiency syndromes.

Abstract: A diagnostic method for immune disorders comprising determining the immunoglobulin production or the DNA (deoxyribonucleic acid) synthesis of peripheral blood lymphocytes by stimulation with a new mitogen derived from either disintegrated microorganisms or culture fluid of microorganisms belonging to Staphylococcus.

Abstract: A method of leukemia or leukemoid disease treatment by administration of a vitamin D derivative with a hydroxyl group at 1.alpha.-position is disclosed. It is believed that the vitamin D derivative with a hydroxyl group at 1.alpha.-position is capable of treating cancer through redifferentiation of cancer cells and that this capability is inherent in vitamin D derivatives with a hydroxyl group at 1.alpha.-position.

Abstract: A method for inhibiting the lowering of immunological function of patients who are suffering from serious renal disorder such as chronic renal failure or uremia which comprises administering 1.alpha.-hydroxycholecalciferol to the patients is disclosed. An agent useful in the practice of the method is also disclosed.
