1目的 评价深低温保存人体同种主动脉的效果。 2方法 取 5段新鲜和 8段低温保存复温后的人体主动脉标本 (保存时间平均 5 31d)在光、电镜下进行观察。 3结果 深低温保存的人主动脉弹性膜及纤维结构保存良好 ,细胞超微结构的改变与保存时间无明显关系。 4结论 深低温保存的人主动脉组织学检查无明显变化 ,保存效果良好。
1 Objective To evaluate the effect of cryopreservation of human aorta. 2 Methods Five sections of fresh and 8 cryogenic preservation after cryogenic preservation of human aortic specimens (save for an average of 531d) were observed under light and electron microscopy. 3 Results Cryopreserved human aortic elastic membrane and fiber structure is well preserved, changes in cell ultrastructure and storage time was not significantly related. 4 Conclusion Cryopreservation of human aortic histology no significant change, the preservation effect is good.
