Abstract: Disclosed are skin immune function controlling agents which contain as the active ingredient a volatile substance capable of stimulating the olfactory receptor, as typified by a specific perfume. By controlling the skin immune function, these agents serve, for example, to enhance the skin barrier function and to prevent or treat skin contact hypersensitivity.

Abstract: A labeled polynucleotide is subjected to hybridization with oligonucleotide probes fixed respectively to regions on a supporting material. With a first restriction enzyme, a single-stranded moiety of the labeled polynucleotide having failed to form a double strand with each probe is separated from a double strand having been formed by the labeled polynucleotide and each probe. First detection data is obtained from each region. A mismatching moiety, at which the labeled polynucleotide and a certain probe have undergone a mismatch binding, is separated with a second restriction enzyme, and second detection data is obtained from each region. The region to which the mismatch polynucleotide was bound is specified in accordance with results of a comparison between the first detection data and the second detection data.

Abstract: A labeled polynucleotide is subjected to hybridization with oligonucleotide probes fixed respectively to regions on a supporting material. With a restriction enzyme, a single-stranded moiety of the labeled polynucleotide having failed to form a double strand with each probe is separated from a double strand having been formed by the labeled polynucleotide and each probe. Thereafter, an electrode is located at a surface of each region on the supporting material, and a voltage is applied to the electrode. The labeled polynucleotide, which has undergone a mismatch binding with a certain oligonucleotide probe, is thus separated from the corresponding region on the supporting material.

Abstract: A skin barrier function recovery and promotion composition containing, as an active ingredient, a fragrance which is effective when evaluated by applying a predetermined stress to a model experimental animal, in a system to which the tested fragrance is not applied, to thereby reduce the skin barrier function of the animal and using this data of the degree of recovery of the skin barrier function as an indicator and evaluating the capability by the difference between this data and data of the degree of recovery of the skin barrier function in a system to which the tested fragrance is applied.

Abstract: An electromagnet device for an electromagnetic contactor is formed of a frame with an opening, a movable-contact supporter slidably disposed in the frame, a movable contact supported by the movable-contact supporter, a movable core connected to the movable-contact supporter, and a stationary core for attracting the movable core. The stationary core includes a base plate for closing the opening of the frame, at least one columnar arm core fixed to the base plate to extend therefrom, and at least one pole piece fixed to the arm core at a side opposite to the base plate. The pole piece provides attracting force to the movable core when the stationary core is energized. In the electromagnetic device, a device for partly interrupting a magnetic path of the stationary core is formed. The interrupting device reduces remanent flux in the stationary core when the stationary core is deenergized.
