[Clinical application and experimental study of homologous-cartilage implantation].
On the basis of 124 cases of homologous-cartilage grafts, the changes of host's tissue structure and immune active cells around the homologous-cartilage were studied. Slices of implantation at different time were investigated by histologic, histochemical, immunopathologic and ultrastructural methods. The results show that the rejection phenomena of homologous-cartilage grafts may be the process of substitution of bone for cartilage, rather than the process of absorption and there are no influences on supporting framework of homologous-cartilage grafts.
