Cell viability can be well preserved under cryopreservation, and this may play an important role on its long-term durability after implantation. However, this may also lead to specific immune rejection. In this review, we discussed the effects of cryopreservation on the antigenicity of homograft cardiac valves, its mechanism and clinical significance of th...             深低温保存技术的出现使同种瓣更广泛地应用于各种心脏外科手术.深低温很大程度上保持了同种瓣的生物活性,这是它能够在体内保持耐久性的重要条件,但随之产生的特异性免疫排斥反应不容忽视.本文讨论了深低温技术对同种瓣抗原性的影响以及移植后的免疫排斥现象、发生机制及其意义. 文摘来源          Objective To evaluate morphologically the effect of cryopreservation of homografts of valved great arteries from late-pregnancy fetus. Methods The homografts, which were obtained from healthy brain-dead fetuses, were soaked in cryoprotectant, equilibrated at 4 ℃, and packed in special freezing bags. Liquid nitrogen vapor was used to reduce the temperature to -196 ℃ to preserve the homografts. After the thawing, the vascular wall was observed by light microscope and electron microscope and the findings were ...             ①目的　用形态学方法评价深低温保存大月龄胎儿血管和瓣膜组织的效果。②方法　同种材料取自大月龄脑死亡胎儿。在冷冻保护液浸泡后置于 4℃冰箱冷平衡 ,特制无菌冷冻袋包装。用液氮蒸气梯度降温方法完成降温 ,- 1 96℃长期保存。复温后光镜、电镜观察血管组织形态并与复温前比较。③结果　修剪后和解冻后的血管及瓣膜细菌培养结果均为阴性。光镜、电镜观察显示解冻后的主动脉基本结构完整 ,胶原纤维和弹力纤维形态结构正常 ,排列规则 ,局部可见黏液样变性以及部分内皮细胞脱落。④结论　本法同种材料的取材、冷冻保存效果可靠。初步建立了综合采集、长期冻存大月龄胎儿血管和瓣膜组织的方法和技术标准 ,为大月龄胎儿血管和瓣膜库的建立及临床应用奠定基础 文摘来源          Objective To investigate the durability of the cryopreserved valved homograft conduit (VHC) used in reconstruction the right ventricular outflow tract (RVOT) and its risk factors. Methods 119 cases undergoing VHC reconstruction the RVOT in our hospital between November 1989 and July 2003. 65 cases were followed-up, including the clinical examination, electroeardiography, chest radiography, echooardiography, or cardiac MRI for detection of development of homograft calcifications, obstruction and conduit valv...             目的探讨深低温保存的同种异体带瓣管道(valved homograft conduit,VHC)在重建小儿右室流出道(right ventricular outflow tract,RVOT)中耐久性情况,及影响其耐久性的危险因素。方法 1989年 11月至2003年7月用VHC重建RVOT,随访65例次临床情况、心电图、X线胸片、心脏超声和心脏MRI。借此了解病儿体内VHC钙化、梗阻和反流情况。用现代统汁方法分析影响VHC耐久性的危险因素。结果 65例次中VHC中位生存时间10．9年,管道生存最长时间12．8年。结论小年龄(≤4岁)、低体重 (≤10 kg)和主动脉VHC是影响VHC耐久性的危险因素。 文摘来源       相关查询: 深低温保存血小板 血小板深低温保存 深 低温保存 有限深 深海盆 深龋的 深地色 深筒仓 深土层 深地下室 基底深  对查询结果不满意
