This experiment was performed to study the biocompatibility of xenograft materials (ABBM. coralline HA). Both autogenous bone grafts and allogenic banked bone were frequently and successfully used to promote regeneration of parts of skeleton. The use of these types of grafts were limited by the cost of donor site operation for autogenous boneor by fear of the risk of infection of allogenic materials. Another type of graft is xenograft which include ABBM and coralline HA. For investigating the biocompatibility, generally many investigators used cancer cell lines or animal cell lines. But cancer cell lines and animal cell lines had functioned different metabolism from normal human cell. So the experiment used normal human osteoblast for compare the biocompatibility of ABBM with coralline HA which were fixed in 24 well base contained culture medium. After 1st, 3rd, 7th, 14th, 28th days, the culture medium were taken out and checked the concentrations ofcalcium( Ca), inorganic phosphate(IP) and alkaline phosphatase(ALP). In another method, histologic samples were investigated after 8weeks of xenograft materials implantated on rabbit's tibia, the bone was cut and made undecalcified ground samples and checked with fluorecent microscope, polarizing microscope, reflection electron microscope and electron probe microanalysis. The statistical results of concentrations (Ca, IP, ALP) of materials in the culture medium have decreasedby day's, which meant that xenograft materials were effective for bone remodelling. The concentrations in the culture medium of ABBM were lower than that of coralline HA, that meant that biocompatibility of ABBM were superior than that of coralline HA. Histologic samples showed that ABBM had better bone remodelling effect than coralline HA. ABBM showed good alizarin red marking lines, more deposition of Ca, IP, and dense color of bone around newly formed osteon and bone trabeculae. it was concluded that ABBM was more biocompatible than corallineHA in vivo and in vitro test
