ABSTRACT:
A process for the production of an unnative and biologically active bonded collagen fiber sheet from human placentae is described, in which process collagen-containing material from placentae is treated with a neutral salt solution, a solution of citric acid and with pepsin. The degraded collagen material obtained in this manner is, where appropriate, treated with a crosslinking agent. The collagen material produced in this manner is used for producing bonded collagen fiber sheets which can be used, for example, as covering for wounds.
