Abstract
By electron microscopy and morphometry cardiomyocytes of 20 rats gamma-irradiated with a single dose of 180.6 microCi/kg and those of 20 rats exposed to hypokinesia for 10 days were examined. Visually the ultrastructural changes of cardiomyocytes were nonspecific. The morphometric examination revealed specific features of ultrastructural rearrangements in the nuclei and mitochondria of cardiomyocytes of rats on day 10 of hypokinesia and irradiation.
摘要
通过电子显微镜和形态计量学方法，对20只单次接受180.6微居里/千克γ射线照射的大鼠以及20只接受10天运动减少的大鼠的心肌细胞进行了检查。肉眼可见，心肌细胞的超微结构变化不具有特异性。形态计量学检查揭示了运动减少和照射后第10天大鼠心肌细胞核和线粒体超微结构重排的特定特征。
