摘要 目的了解混合白膜层(BC)法制备的洗涤混合血小板(洗涤混合BC-PC)的质量和体外功能,为临床应用提供质量依据。方法400ml/袋新鲜全血在4~6h内分离出的BC在22℃静置过夜,6袋同血型的BCs混合、制备成BGPC,用生理盐水洗涤,用血细胞计数仪测定该洗涤混合BC-PC的血小板含量和红细胞残留量、用Nageotte白细胞计数板测定白细胞残留量、用比浊法测定最大聚集率、用流式细胞计数仪测定CD41和CD62p阳性表达率。并测定该制品的pH值和血浆蛋白清除率。结果血小板含量≥2.5×10^11/袋,白细胞的残留量达到10^6/袋,血浆蛋白清除率≥98%,胶原蛋白诱导的最大聚集率〉90%,CD62p阳性表达率平均为19.52%。结论生理盐水洗涤混合BP—PCs的质量符合单采血小板和洗涤红细胞的标准,具有较好的聚集功能,洗涤并未加强血小板的活化,可以用于临床输注。
