nbsp;each other and compare them with the autografting group.Results 1.After treated by：program freezing，the maximum load of the allografts has no evident decrease and the cell activity of allografts was preserved well，the frozen hurt after program freezing was more slight than －80℃ deepfrozen，2.No evident reject reaction can be seen during the healing process after deep frozen and the reject reaction declined as the time pass by.3.Three weeks afer the allografting，there was no significant difference between the two al lografting groups in maximum load(P＞0.05)，Eight weeks later，the maximum load of the group that was preserved by liquid nitrogen after program freezing(76.60±4.67)N was better than the group that was preserved by －80℃ deepfrozen(75.99±4.20) and similar with the autografting group(76.72±2.55).4.The healing process and histological behavior of the two deepfrozen groups are similar with the autografting group，and the program freezing group is better.Conclusion 1.The healing process of the two deepfrozen allografting groups is similar with the autografting group.2.The program freezing method is better than the traditional －80℃ deepfrozen method 上一页 [1] [2] [3] [4] [5] [6] 下一页
