[摘要]目的 探讨重组CTLA4Ig及IκBα重组腺病毒载体延长烧伤创面皮片移植存活情况。 方法 采用Wistar大鼠36只,随机分为3组,1组:正常对照组,2组:用AdCTLA4Ig液室温浸泡转染1h,3组:用Adv CD40LIg-IRES2-CTLA4Ig液室温浸泡转染1h。麻醉后常规背部备皮,在4cm×4cm面积上涂3%凝固汽油2ml,燃烧20s,致大鼠背部皮肤Ⅲ度烧伤,于烧伤后第3天,将所制备1.0cm×2.0cm大小长方形皮瓣移植于创面,加压包扎。观察重组腺病毒载体转染移植物后,在大鼠背部烧伤创面移植人断层皮肤的存活情况的影响。 结果 重组腺病毒载体能延长大鼠烧伤创面移植人断层皮肤的存活时间。 结论 重组腺病毒可用于延长烧伤创面异基因移植皮肤的存活期。[关键词] CTLA4Ig;IκBα;腺病毒,重组;异体移植
