摘要 目的:探讨肝细胞生长因子(HGF)在心脏移植缺血再灌注损伤的保护作用。方法:健康雄性Wistar大鼠40只,建立大鼠同系异位心脏移植模型。随机分为3组:假手术组、对照组、实验组(供心切取时用含HGF100 mg/L 4℃改良ST.Thoms液10 ml主动脉根部灌注停跳)。术后5 h测定血清中丙二醛(MDA)、超氧化物歧化酶(SOD)、肌酸激酶同工酶(CK-MB)含量,TUNEL法染色检测心肌细胞凋亡,电镜观测心肌细胞超微结构变化。结果:实验组MDA、CK-MB明显减少(P<0.01),SOD明显增加(P<0.01),心肌细胞凋亡指数显著减低(P<0.01),心肌超微结构改变明显减轻。结论:HGF能抑制心肌细胞凋亡,对心脏移植缺血再灌注损伤有保护作用。
