摘要： A porous and transparent hydrated gel is prepared from a poly(vinyl alcohol) solution in a mixed solvent consisting of water and an water-miscible organic solvent. Upon cooling the poly(vinyl alcohol) solution below room temperature, a gel is formed as a consequence of crystallization of poly(vinyl alcohol) molecules. Exchange of the organic solvent included in the gel with water produces a hydrated gel of poly(vinyl alcohol) which has a high tensile strength, a high water content, and a high light transmittance.

摘要： An artificial hair having a physiologically active surface which is formed by a such manner that protein (collagen) molecules are bonded chemically to the graft-polymerized chains introduced onto the surface of the artificial hair. When the artificial hair is implanted into a human body skin, the collagen layer 11 fixed to the surface of the artificial hair having a root part 12 is integrally assimilated and bonded to collagens in the epidermis 4, the corium layer 5, the subcutaneous tissue 6 and the galea 7, whereby the artificial hair can be firmly fixed. Thus, this artificial hair exhibits a low infection rate, a high success rate and cannot be accompanied by down-growth phenomenon.

摘要： Disclosed are a crosslinked gelatin microspheres containing CSF and a water soluble CSF-gelatin conjugate. Both the microspheres and the water soluble conjugate provide an improved CSF stability. They have a high potentiation on the antitumor activity of macrophages in respect of the CSF amount and the time required for macrophage activation and are effective in maintaining their activated state for a long period, compared with the native CSF. The mechanism of macrophage activation by the microspheres containing CSF is mediated via phagocytosis and different from that by native CSF, which is believed to activate macrophages via cell surface receptor. The species specificity of CSF may be abrogated when the CSF is internalized into macrophages through phagocytosis.
