Some biological properties of bovine trypsinized fascia xenografts

Trypsinized, lyophilized and radiation-sterilized bovine fascia grafts were used for treatment of muscle and peritoneal defects induced in mice. The survival rate, general and surgery region condition of normal and pregnant mice after transplantation were investigated. The influence of grafts on the adjacent tissues and on regeneration processes was also examined. It is suggested that the grafts prepared by this new method, owing to their good tolerance and long resorption time, could be used in a human clinic.
