Objective To develop a new tissue engineering bone material which has an antiinfective function. Methods Collagen loaded bio-derived bone material was made by using type I collagen and allograft bone. WO-1was absorbed to collagen loaded bio-derived bone, then the morphological feature of the new bone material was observed by scanning electronic microscopy.3 H tetracycline was diluted by WO-1 solution, and was absorbed to collagen loaded bio-derived bone，then the releasing kinetics of WO-1 was detected by 3 Htetracycline in vitro. WO-1 bioderived bone material was grafted into a culturemedium with staphylococcus aureus, escherichia coli, and pseudomonas aeruginosato observe its bacteriostasis ability. WO-1 bio-derived bone material was grafted into radius of defected rabbits, the concentration of WO-1 was detected onthe 9th, 16th, 23th, and 30th day byHLPC in blood, in bone and in muscle. The bacteriostasis ability of WO-1 loaded bio-derived bone was tested in vitro and in vivo. Results WO-1 loaded bioderived bone maintained natural network pore system and the surface of network pore system was coated with collagen membrane. The release of WO-1 from WO-1 loaded bioderived bone showed bursting release on the 1st day, then showed stable release. WO-1 loaded bioderived bone showed lasting and stable bacteriostasis to common pathogens of orthopaedic infections. The high concentration of WO-1 was observed in bone tissue and in muscle tissue at differenttime points and the difference among groups had no significance（P＞0.05）, while the concentration of WO-1 in blood was very low（P＜0.05). Conclusion WO-1 loaded bioderived bone has good capability of drug controlled-release and bacteriostasis.
