摘要 目的 液氮直投法及程序冷冻法冻存人卵巢组织效果的比较研究.方法 采用液氮直投法及程序冷冻法冻存人卵巢组织,解冻后苏木素-伊红染色检测冷冻前后各级卵泡(始基卵泡、初级卵泡和次级卵泡)的组织形态,然后将卵巢组织体外培养3天,检测培养上清雌激素水平.结果 液氮直投法、程序冷冻法始基卵泡形态正常率分别为72.96%、81.87%,差异有统计学意义(χ2=11.27,P〈0.05);初级卵泡形态正常率分别为58.62%、34.48%,差异有统计学意义(χ2=6.79,P〈0.05).第3天、第6天血清雌激素水平检测,液氮直投法与程序冷冻法比较差异无统计学意义(108.38±9.27 vs 105.15±9.13,151.08±16.64 vs 147.38±20.48,均P〉0.05).结论 程序冷冻法以及液氮直投法可有效保存卵巢组织,对卵巢组织和功能的影响较小,而且液氮直投法操作更简便、快捷.
