摘要 目的观察体外循环(CPB)对肺泡表面活性蛋白A(SP-A)组成的影响。方法以6周龄左右的猪为实验动物,常规建立CPB,于CPB前、CPB60min、120min及CPB结束3h以纤维支气管镜吸取支气管肺泡灌洗液(BALF),通过蛋白免疫印迹反应法测定SP-A。结果SP-A总量在CPB过程中明显下降,CPB60min和120min时与CPB前比较差别有统计学意义(P=0.045,0.017),但在CPB结束3h时基本恢复至CPB前水平;36.70ku组分在CPB过程中无明显变化,但在CPB结束3h明显增加(P=0.034);25.79ku组分在CPB过程中明显降低,在CPB后也未明显恢复(P=0.044,0.022)。结论在CPB过程中,SP-A总量减少,其不同组分的变化则不相同。
