摘要:
The invention is related to antibodies which specifically react with connective tissue type-human mast cells, a production method of the antibodies, hybridomas which produce the antibodies, a production method of the hybridomas and antigen proteins recognized by the antibodies. After cord blood cells were cultured in the presence of SCF and IL-6, they were further cocultured with primary culture of human skin fibroblasts, and connective tissue type-human mast cells were thus obtained. A rat was immunized using the cells, hybridomas were prepared and selected by an ordinary method, and novel monoclonal antibodies were harvested from the culture supernatant of the selected hybridomas. The monoclonal antibodies specifically reacted with connective tissue type-human mast cells.

A brushless motor includes a stationary member; a rotating member rotatably supported with respect to the stationary member; a stator provided in the stationary member and provided with a stator coil for generating current magnetic field under an exciting state; and a rotor magnet provided in the rotating member for obtaining a revolutionary power due to an electromagnetic mutual effect with the current magnet field of the stator coil. The rotor magnet is formed such that segment-shaped magnets are placed annularly with predetermined gaps circumferentially. The gaps are filled with a magnetic resin material.

A suspension mechanism for a wheeled vehicle, comprising a suspension arm having a pair of arm portions aligned with each other in a lateral direction of the vehicle body and pivotally connected to the vehicle body for being rockable about a first axis fixed with respect to the vehicle body and transverse to the vehicle body; a wheel axle which is pivotally connected to the suspension arm and rockable about a second axis fixed with respect to the suspension arm and perpendicular to the first axis and which has a spindle portion having a center axis about which a wheel-and-tire assembly is rotatable; and angle adjusting means engaging the suspension arm and the wheel axle and adapted to permit adjustment of the angular position of the wheel axle with respect to the suspension arm about the second axis.
摘要:
A television signal is encoded by the use of a sampling pulse synchronized with a color subcarrier frequency included in an input television signal, the encoded signal is compressed and recorded in a memory for later reproduction of a desired compressed picture image having a desired size and center position, the recorded signal is reproduced under the control of a clock pulse signal produced in synchronism with a sync signal obtained in a studio, for example, and the reproduced signal is corrected by inverting the polarity of the chroma component according to frame information at the time of recording of said reproduced signal.Thus, it is possible to freely obtain phase coupling of different synchronizing signals; for instance, it is possible to bring the phase of a different television signal of a different synchronization system into coincidence with the phase of a central synchronization signal and it is possible to reproduce an object image optionally compressed on a TV display screen.

(PROBLEMS) To provide a highly safe dietetic composition originating in green coffee beans by which excellent dietetic effects can be obtained and which contributes to the prevention and treatment of life style-related diseases such as diabetes. (MEANS FOR SOLVING PROBLEMS) A dietetic composition characterized by comprising, as the active ingredient, a polar solvent extract of defatted green coffee beans. It is preferable that the above-described polar solvent extract is an extract obtained by using water-containing ethanol, still preferably water-containing ethanol having an ethanol concentration of from 40 to 90% (wt/wt). It is preferable that the above-described defatted green coffee beans are those obtained by extracting green coffee beans with N-hexane to thereby separate oily components therefrom. It is recommended to combine the above-described dietetic composition with one or more members selected from among salacia extract, evening primrose extract, sesamine and garcinia. This dietetic composition is usable as a material for foods, drinks, drugs, or skin preparations for external use.
摘要:
In a single screw compressor, gates (51) of gate rotors (50) are to be engaged with spiral grooves (41) of a screw rotor (40). In each spiral groove (41) of the screw rotor (40), an area extending from a start point of the spiral groove (41) to a position in a compression stroke is a suction-side portion (45), and the remaining portion (portion up to a terminal point of the spiral groove (41)) is a discharge-side portion (46). In the discharge-side portion (46), a clearance between a wall surface (42, 43, 44) therein and the gate (51) is substantially “0 (zero).” A clearance between the wall surface (42, 43, 44) in the suction-side portion (45) and the gate (51) is wider than that between the wall surface (42, 43, 44) in the discharge-side portion (46) and the gate (51), and is gradually narrowed from the start point toward the terminal point in the spiral groove (41).

This invention provides an anti-inflammatory agent or the like which is safer and less adverse and has the great effectiveness to prevent and treat arthritis, or the like. An anti-inflammatory agent or the like in this invention is characterized by comprising anthocyanidin and gingerol as an active substance. Also, the abovementioned anthocyanidin and gingerol are preferably extracted from red ginger.
摘要:
A mast cell surface antigen, DNA thereof and an antibody against the antigen are provided. The amino acid sequence of this mast cell surface antigen is the translation of the coding region of its DNA. The base sequence of this DNA has been clarified in the following manner. Namely, mast cells obtained by incubating cord blood monocular cells are co-incubated with primary culture of fibroblasts to give connective tissue type mast cells (MC-TC). Then mRNA is extracted from this MC-TC cell extraction and a cDNA library is constructed therefrom. Immunological screening is carried out with the use of anti-MC-TC antiserum and the base sequence of the positive clone thus obtained is identified. Owing to the clarification of the amino acid sequence of this mast cell antigen, it becomes possible to reveal the role of mast cells in the pathology of allergic diseases and thus an antibody against mast cells can be easily obtained.
