为判定和鉴别用染色方法所显示的心肌早期病变与制片过程中可能出现的死后人为改变,作者观察了心肌在各种实验性人为损伤条件下的形态改变。实验证明心肌是较易发生死后人为改变的组织,特别是取材时的人为损伤改变及染色性质,在某种程度上类似生前早期病变,故尤应引起重视。提出并讨论了各种人为改变的形态特征、多种染色方法的结果、判定和鉴别心肌人为改变与早期病变的方法。 In order to identify and identify possible early myocardial lesions and possible post-mortem changes during staining, we examined the morphological changes of myocardium under various experimental conditions of human injury. Experiments show that myocardium is more prone to death after artificial changes in the organization, especially when taken from the human injury changes and staining properties, in a way similar to the early life lesions, it should be especially emphasized. A variety of man-made morphological changes, the results of a variety of staining methods, and the method of judging and identifying myocardial changes and early lesions were proposed and discussed.
