Abstract: The purpose of the present device is to provide a face massage roller, which achieves more excellent massaging effect than conventional roller type face massage rollers. A face massage roller is provided having cylindrical 1st, 2nd, 3rd, 4th and 5th rollers, which are supported by shafts in a rotatable state in a frame part of a head part installed at a tip of a handle part, wherein the 1st, 3rd and 5th rollers are mutually parallel and fall at right angles with the direction of the longitudinal axis of the handle part, and the rotary central axes of the 2nd and 4th rollers form a predetermined angle of inclination with the direction of the rotary central axis of the 3rd roller, so that the 2nd and 4th rollers, which are on either side of the 3rd roller, assume an approximately Japanese character “” form.

Abstract: The purpose of the present device is to provide a face massage roller, which has a means to fix the magnets and the ceramic part(s) firmly without using an adhesive, which can produce a good massaging performance for a long term, and which reduces the burden due to defects generated after the selling of the products. This problem is solved by a face massage roller, having a presser member, lying between a back lid and a frame part, in which two or more rollers are supported by shafts, and being fixed to the back lid by welding, in such a way that a far-infrared ray radiation material part is between the inner side surface of the back lid and the presser member, under the two or more rollers, and the presser member retains the far-infrared ray radiation material part on the inner side surface of the back lid by welding fixation.

Abstract: An improved process for the preparation of gamma globulin suitable for intravenous administration comprises dissolving gamma globulin precipitated from blood or blood products in a solution, separating non-dissolved precipitate from the solution, adding polyethylene glycol to the separated solution, separating precipitate from the polyethylene glycol solution, increasing the polyethylene glycol concentration in the solution, separating precipitated purified gamma globulin from the higher concentrated polyethylene glycol solution, dissolving the purified gamma globulin in a solution suitable for intravenous administration, which process is improved by dissolving the gamma globulin precipitated from blood in a solution having a neutral pH, adding polyethylene glycol in the first step to a concentration of 4.0-5.

Abstract: A method of preparing gamma globulin suitable for intravenous administration comprising a first step of treating a supernatant liquid separated from human blood plasma with ethanol under conditions of a pH of 5.5 to 6.5, an ethanol concentration of 30 to 35%, and a protein concentration of 1 to 2% by weight.

Abstract: The method of preparing immunoglobulin (IgG) suitable for intravenous administration comprising the fractionation of Cohn Plasma Fraction II with polyethylene glycol having a molecular weight of 4000 at predetermined concentrations and under selected pH conditions.
