[Cellulose implants--biostability and tissue reaction]

In order to test blood detoxication systems on cellulose basis (hollow fibers as separation material) histomorphological examinations were performed after incorporation in 10 rabbits. Already after 12 days granulation tissue around the cellulose fibers was found as foreign body reaction, but the implants remain uninjured up to 86 days. The lateral stability of the hollow fibers was unchanged. Further investigations are necessary on the radial stability and the transport properties of the cellulose fibers.
