Development of sterilization and storage processes of Xeno-skins by gamma irradiation for the Industrialization as dressing materials

Allografts have been increased in concerns as treatment methods to be use in replacement and reconstruction procedures of tissue. The major concern about tissue and bone transplantation is the risk of transferring bacteria, viruses from recipient to the donors, especially from different species. To avoid these risks, tissue and bone banks use many different sterilization methods such as a deep-frozenness, freeze-drying ethylene oxide-sterilization and gamma-irradiation. Among these methods, gamma-irradiation has been widely used to sterilize the tissue for allograft and xenograft safety. Gamma irradiation could be an effective method for sterilization of soft tissue for the development of xenografts. Also, this study suggests the potential of development as tissue graft with the improved mechanical property of the structural stability and protection of tissue materials by antioxidant on porcine skin irradiated for sterilization and storage process
