発明の名称 (英語) MEDICAL SUBSTITUTE MEMBRANE, USE THEREOF, AND METHOD FOR REPAIR OF MEMBRANE TISSUE IN LIVING BODY
発明の概要(英語) The object is to overcome the disadvantages of a conventional lyophilized amniotic membrane or the like which causes damages in a cell membrane or amniotic membrane tissue and is therefore not suitable for use as a substitute membrane for a membrane tissue in a living body, and to provide a novel medical substitute membrane comprising a dry amniotic membrane, which can be used as a substitute membrane for a membrane tissue in a living body. Disclosed is a dry amniotic membrane which is produced by drying a fresh amniotic membrane that envelopes an embryo of an animal including human and which can be used as a substitute membrane for a membrane tissue in a living body. The dry amniotic membrane is dehydrated and dried so that the dry amniotic membrane can be stored in a dry air in a sterile state. When hydrated again by immersing in water or a buffer solution, the amniotic membrane still has an epithelial cell, a basement membrane and a connective tissue which constitute the fresh amniotic membrane. The dry amniotic membrane is useful as a medical substitute membrane for a membrane tissue in a living body such as a dura mater, a meninx, a pericardium, a pleura and a peritoneum.
