通过40只家兔的实验研究与一系列观察,证明异体骨经过液氮冷冻,可以降低其抗原性,移植后无异物排斥反应,并可诱导新骨形成。冷冻异体骨移植后,经过爬行代替,可完全转化为正常骨结构。
Experimental studies and a series of observations in 40 rabbits demonstrated that allogeneic bone can be reduced in antigenicity by liquid nitrogen freezing without any foreign body rejection after transplantation and can induce new bone formation. After cryo-allogeneic bone transplantation, after crawling instead, it can be completely transformed into the normal bone structure.
