[Study of antibody against protein in human allografts of decalcified bones].

The result of study on antibody against protein in human allograft of decalcified bones was reported in this paper. 50 cases with allografts of decalcified bones were detected for sero-antibodies by indirect method of ELISA. The antigens used were extracted protein from the human decalcified bones. Among them, 32 cases showed positive reaction including complete bone graft healing in 30 cases, incomplete healing in one and failed in one cases success rate 98% The other 18 cases showed negative reaction. Neither the Positivith nor the titer of sero-antibody interfered with the healing of allograft.
