Title: Thrombolytic agent
Inventor: SAWAI KIICHI
IPC: A61P7/02
Filed: 1985-03-22
Abstract: PURPOSE:To provide an inexpensive and high-safety thrombolytic agent containing semi-alkali protease or its polyalkylene glycolmodified derivative as an active component. CONSTITUTION:The objective agent contains semi-alkali protease or its polyalkylene glycol-modified derivative (e.g. semi-alkali protease modified with polyethylene glycol) as an active component. It may further contain one or more stabilizing carrier for drug preparation such as a polymer (e.g. amino acid). Enzymes such as urokinase have hitherto been used as thrombolytic agents, however, the enzymatic thrombolytic agent is expensive because the active component is extracted from living body and is administered only in the form of injection from the viewpoint of absorbability and stability. Semi- alkali protease can be produced industrially in a mass by the cultivation of Aspergillus melleus and the absorbability and stability of the agent in the oral administration can be improved by modifying with polyalkylene glycol.

Title: Earthenware and its production
Inventor: ITO MASAAKI
IPC: A47K1/04
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To suppress the surface staining of earthenware by constituting the outermost layer of a glaze substantially only with glass components and pigments. SOLUTION: The outermost of a glaze is constituted only with glass components and pigments or only with galss components to substantially causes no crack expansion in silica particle areas accompanied by remaining of silica particles or a corrosion reaction resulting in deletion of the silica particles. As a result, the formation of crevice due to solubilization or corrosion is suppressed, and the depression becoming a growing bed of microorganisms and/or a staining point is suppressed, in other words, a pottery is inhibited from being stained. In a preferred embodiment, the outermost surface layer includes no silica particle of >=10 μm. Under these conditions, the residual strain on the boundary face between the glass phase and the silica particles during production when the temperature is lowered becomes small and resistant to crack formation is improved.
