克山病尸检材料的电子显微镜及组织学检查结果提示,心肌细胞线粒体及其某些酶类有一定的形态学变化。应用克山病病区粮饲养动物的实验证明,心肌细胞中某些呼吸酶也具有较大的易损伤性。但是,过去对克山病病人心肌细胞的呼吸酶活性尚无报道。 Keshan disease autopsy material electron microscopy and histological examination results suggest that myocardial cells mitochondria and some of its enzymes have some morphological changes. Application Keshan disease wilt animal experiments show that some respiratory enzymes in myocardial cells also have greater vulnerability. However, no respiratory enzyme activity has been reported on myocardial cells of Keshan patients in the past.
