Abstract:
AIM: To investigate the effects of deep-frozen treatment on the immune response of bone-patellar tendon-bone(BPB) xenograft rejection.METHODS: A muscle pocket model was used to study the immune response of rat to deep-frozen treated BPB xenograft from guinea pig,autograft and fresh xenograft served as controls.The expression of T-cell surface activation antigen CD25 in the peripheral blood and the morphological changes of the implants were used to measure the immune response.RESULTS: The expression of CD25 in CD4+,CD8+ cells greatly increased 3 d after fresh BPB xenograft,the obvious difference to that of autograft(P
