许多研究显示在接受心肺旁路（CPB）的心脏手术者中改变了细胞免疫性。天然杀伤细胞（NK）细胞毒活性中CPB后受到抑制。NK细胞具有训u和破坏某些被感染和肿瘤细胞的能力。另外还可释放在细胞介导免疫反应中起重要作用的干扰百a和一些细胞因子、免疫反应受损害可增加败血症住多
Many studies have shown altered cellular immunity in cardiac surgery undergoing cardiopulmonary bypass (CPB). Natural killer (NK) cytotoxic activity was inhibited after CPB. NK cells have the ability to discipline u and destroy certain infected and tumor cells. In addition can also release interference in the cell-mediated immune response play an important role and some cytokines, immune response damage can increase sepsis live more
