    • PURPOSE: To easily eliminate a periosteum from a bone by generating a contact of the periosteum with the solution of an enzyme, which is selected from a group of proteolytic enzyme and collagen digestive enzyme and the mixture thereof, for a sufficient time for separating the periosteum from a surface of a bone in the condition for accelerating the activity of the enzyme. CONSTITUTION: Proteolytic enzyme and collagen digestive enzyme effective for separating a periosteum or the mixture thereof can be used. As an appropriate proteolytic enzyme, trypsin and kymotripsin can be used. As an appropriate collagen digestive enzyme, collagenase or the like can be used. A periosteum is brought into contact with the enzyme solution, which includes proteolytic enzyme and collagen digestive enzyme, and the bone is separated from the first enzyme solution, and continuously, the bone having a periosteum, which still has a little nature, is brought into contact with a second enzyme solution, which includes any one of collagen digestive enzyme or proteolytic enzyme. The bone is brought into contact with the enzyme solution for one-several hours necessary for accelerating separation and elimination of the periosteum from the bone.
