Abstract: An apparatus for vibrating the ulna in vivo includes a main post provided upright on a base stand, and a horizontally extending upper arm secured to the upper part of the main post for vertical movement. The apparatus also includes a plate for fixing the back of the hand; the plate is secured to the end of the upper arm for free movement at an arbitrary angle of inclination. A lower arm which is secured for vertical movement to the lower part of the main post and extending in the same horizontal direction as the upper arm is also provided. In addition, an excitor is mounted on the lower arm for sliding movement in the axial direction of the lower arm and in a horizontal direction perpendicular thereto, and a brachium resting plate is fixed ahead of the excitor.

Abstract: A method of the quantitative measurement of antigens and antibodies by reacting antibody- or antigen-sensitized insoluble carrier particles with a corresponding antigen or antibody or a mixture thereof in a sample, irradiating the reaction mixture with light of a specific wavelength to measure the transmitted light at two or more points of time as the reaction proceeds, and then evaluating an increase in absorbance or percent absorption of the reaction mixture for a given period of time, and an apparatus for use therein.
