用5例克山病患者尸检材料及5例其他疾患尸检材料,取心脏进行三磷酸腺苷酶(ATPase)及脱氧核糖核酸(DNA)的组织化学检查,在克山病心脏中呈颗粒变性的心肌纤维对ATPase染色反应不稳定,有时阳性,有时为阴性,肌溶坏死部分ATPase染色呈弥散性反应,瘢痕部分ATPase染色旧阴性,小血管在新解瘢痕中者呈阳性反应,陈瘢痕中者呈阴性反应,单核细胞反应区亦呈阴性反应,结构正常的心肌纤维中ATPaso The autopsy materials of 5 patients with Keshan disease and autopsy materials of 5 other diseases were used to perform histochemical examination of adenosine triphosphatase (ATPase) and deoxyribonucleic acid (DNA), and myocardial fibrosis in Keshan disease ATPase staining reaction instability, sometimes positive, sometimes negative, muscle necrosis part of the ATPase staining was diffuse reaction, scar some ATPase staining old negative, small vessels in the new solution of scarring were positive reaction, Chen scar in the negative reaction , Monocyte reaction area also showed a negative reaction, the structure of normal myocardial fibers ATPaso
