摘要： 目的观察急性心肌梗死时心传导系统糖蛋白表达。方法运用花生凝集素(PNA),对8例急性心肌梗死亡者的心传导系统标本进行亲和组化染色。结果PNA有7例呈现强阳性,1例出现弱阳性。结论房室结传导细胞在缺血时细胞膜表达PNA受体,提示急性心肌梗死时房室结细胞和工作心肌都不同程度受累,并且细胞病理改变机制可能相关或类似。

Abstract: Objective To study the expression of the glycoprotein in atrioventricular cell membrane of the acute myocardial infarction.Methods The glycoprotein changes occurred at the atrioventricular cell membrane of the acute myocardial infarction of8cases were observed by using immunohistochemical methods.Results Positive staining of PNA could be observed in atrioventricular cell membrane.Conclu - sion This experiment proved that atrioventricular cell membrane expressed D-galactose as same as my - ocardial cell membrane in the acute myocardial infarction.
