山羊同种部份移植的实验研究

<正> 骨的保存和移植在国内、外曾有过许多报导和专著。R.B.Olds指出:“同种骨移植在-20℃或-30℃冰冻3—4个月或-76℃至少冰冻21—25天,移植后得到好的效果”。并认为感染的和未感染的移植物,其吸收是相同的。Fred Langer等认为同种移植骨可使动物产生细胞和体液免疫,但可通过低温冰冻来克服,并证明冰冻在-20℃、

Experimental studies of homogenous Partial bone grafting in goats

Nine goats with negative blood cross reactions were allocated in two groups. The four goats in the first group were used for fresh homogeneous partial bone grafting. The Second group consisted of a donor and the other four goats which were used for frozen homogeneons partial bone grafting after the bone materials had been prepared under -18℃ for ten days. The locations of transplantation were on the inoide of metacarpue or metarsus. The heaeing states were examined Clinically, histologically and radiographically at 0.5, 1.0, 2.0, 和4.0 mo.after the operation. Although all the tested goats had been healing well.The frozen materials gave faster and better results, than the fresh bone materials. After grafting with fresh bone materials immogenic reaction was Observed.
