Abstract: A process for producing a polyether polymer by polymerizing a monomer having an oxirane group in the presence of a Lewis base having no active hydrogen such as, for example, a nitrile compound, a cyclic ether compound or an ester compound; and a polyether polymer produced by this process. Thus, a polyether polymer having a minimized amount of undesirable crosslinked product can be produced without reduction of polymerization activity.

Abstract: Disclosed are a mammalian trehalose receptor which comprises a protein comprising any of the amino acid sequences of SEQ ID NOs: 1, 2, 3 and 5; or a protein comprising any of the amino acid sequences of SEQ ID NOs: 1, 4 and 5; and a method for detecting trehalose using an animal cell in which the trehalose receptor has been expressed.

Abstract: A mucosal immunoregulatory agent comprising trehalose, which has neither excessive stress nor care for side effects even when administrated repeatedly, is administered and provides mucosal immunoregulatory activity.

Abstract: A physiologically active extract comprising an ethyl acetate-soluble ingredient of an indigo plant, which is obtainable by soaking a raw indigo plant in an organic solvent used for extraction. The ethyl acetate-soluble ingredient includes tryptanthrin, 3,5,4′-trihydroxy-6,7-methylenedioxy-flavone, kaempferol, 3,5,7,4′-tetrahydroxy-6-methoxy-flavone, gallic acid, caffeic acid, indirubin, pheophorbide a, and methylpheophorbide a.

Abstract: The object of the present invention is to provide a mucosal immunoregulatory agent which has neither excessive stress nor care for side effects even when administrated repeatedly, and solves the objected by providing the mucosal immunoregulatory agent comprising trehalose.

Abstract: An orally or parenterally administrable agent for anti-osteoporosis, comprising trehalose as an effective ingredient and optionally another ingredients, that exerts a satisfactory therapeutic/prophylactic effect on osteoporosis with lesser side effects.

Abstract: A physiologically active extract comprising an ethyl acetate-soluble ingredient of an indigo plant, which is obtainable by soaking a raw indigo plant in an organic solvent used for extraction. The ethyl acetate-soluble ingredient includes tryptanthrin, 3,5,4′-trihydroxy-6,7-methylenedioxy-flavone, kaempferol, 3,5,7,4′-tetrahydroxy-6-methoxy-flavone, gallic acid, caffeic acid, indirubin, pheophorbide a, and methylpheophorbide a.

Abstract: An antitumor agent comprising as an effective ingredient 3-?4-hydroxy-3,5-bis(3-methyl-2-butenyl)phenyl!-2-propenoic acid obtained from propolis and/or its physiologically acceptable salt(s). The agent exerts a strong antitumor activity without substantially inducing side effects.

Abstract: The phases of a multi-phase stepping motor (16) are individually energized to rotate the motor shaft (14) to a desired step position. A sensor (12), (27) driven by the shaft (14) is constructed to generate a plurality of position signals (L1), (L2), (L3) equal in number to the motor phases. The position signals (L1), (L2), (L3) are symmetrical and are displaced in phase from each other by the angle (15.degree.) between adjacent shaft steps. These signals (L1), (L2), (L3) are decoded to energize the motor phases in such a manner as to rotate the shaft (14) to a next step during rotation of the shaft (14). A hold decoder (26) decodes the position signals (L1), (12), (13) to energize the motor phases in such a manner as to hold the shaft (14) at the desired step when rotation of the shaft (14) is stopped. If the shaft (14) is manually rotated to another shaft position, the hold decoder (26) will energize the motor phases in a different manner so as to hold the shaft (14) at the new step.
