英文摘要 | Porous biphasic calcium phosphate ceramic rods were implanted in dorsal muscles of domestic pigs and dogs, and also implanted in subcutis of domestic pigs. Samples were harvested at 30 days, 45 days, 60 days and 120 days respectively after implantation. Histological observation showed that porous biphasic calcium phosphate ceramic could induce osteogenesis in domestic pigs. Compared to the osteoinduction in dogs, the osteoinduction in domestic pigs was at a higher rate. At 45 days postoperation, obvious bone formation could be detected in the samples implanted in the dorsal muscles of domestic pigs, but in dogs, obvious bone formation only could be observed 60 days after implantation. A new phenomenon was evident that the calcium phosphate ceramicinduced osteogenesis in domestic pigs may be due to the early tissure responses in the ceramics. |
