A possibility of a peculiar method for division of myocardial cells and nuclei--longitudinal splitting--has been studied in hypertrophic hearts of 19 corpses. Morphological examination of the myocardium (separate weighing of the cardiac ventricles, measuring of myocardial components and muscular fibres in microphotos of transversal sections) has not revealed any signs of longitudinal fibres splitting: their average thickness either increase or remain the same with growth of muscular mass, and per cent of thin and thick fibres remains within limits of unreliable fluctuations. Analysis of serial transversal sections of muscular fibres and their micrometry confirm the reality of longitudinal splitting of the nuclei which is realized through several steps and depends on the degree of hypertrophy of muscular fibres.
在19具尸体的肥厚心脏中研究了一种心肌细胞和细胞核独特的分裂方法——纵向分裂的可能性。对心肌进行形态学检查（分别称量心室重量、在横切面显微照片中测量心肌成分和肌纤维）未发现任何纵向纤维分裂的迹象：随着肌肉质量的增加，它们的平均厚度要么增加，要么保持不变，细纤维和粗纤维的百分比仍在不可靠波动范围内。对肌纤维连续横切面的分析及其测微法证实了细胞核纵向分裂的真实性，这种分裂通过几个步骤实现，并取决于肌纤维的肥大程度。
