摘要

Purpose This study evaluated the osteogenetic capability of Ling Zhi-8 (LZ-8; a protein purified from traditional Chinese medicine [lingzhi]) compared with recombinant human bone morphogenic protein-2 (rhBMP-2) in a standardized bony defect using a rabbit sinus model. Materials and Methods Twelve male New Zealand white rabbits (18 to 24 weeks old, 3.3 to 3.8 kg) were included in the study. Implants of normal saline 0.1 mg, rhBMP-2 0.1 mg, and LZ-8 0.1 mg were each mixed with a uniform biodegradable polyurethane-based material (Nasopore). The implants were inserted in a standardized bony defect of the nasal bone created by a 2.5-mm trephine bur. The rabbits were sacrificed at 1, 2, 4, and 8 weeks postoperatively. Volume computerized tomographic and histomorphometric examinations were used to evaluate the quantity and quality of regenerated bone. Results At postoperative week 4, radiography showed that the new bone volume was significantly larger in the rhBMP-2 group compared with the LZ-8 group (P =.041) and the control group (P =.015). Histomorphometrically, better wound healing of the rhBMP-2 group was found during the healing phase compared with the other 2 groups. Conclusion The biomaterial implants using rhBMP-2 and LZ-8 had good biocompatibility and osteogenetic capabilities in the rabbit sinus model. Bone healing in rhBMP-2-treated defects was excellent and showed a significant difference compared with LZ-8. However, LZ-8-treated defects also exhibited bone regeneration, and this traditional Chinese medicine may possess osteogenic potential. Further investigations of the mechanism and application of this protein in osteogenesis are needed.
