Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.

hyperacute rejection:超急排斥
超急排斥(hyperacute rejection)反应一般在移植后24小时发生. 目前认为,此种排斥主要由于ABO血型抗体或抗Ⅰ类主要组织相容性抗原的抗体引起的. 受者反复多次接受输血,妊娠或既往曾做过某种同种移植,其体内就有可能存在这类抗体. 在肾移植中,
