The study was aimed at quantitative and qualitative evaluation of the muscle fibres and the axonal endings of the neuromuscular junctions in the soleus muscle of animals after a space flight on Biosputnik 936. Ultrastructural morphometric studies of the muscle fibres demonstrated diminished volume of sarcomer and accumulation of glycogen granules. The mean number of mitochondrial profiles decreased. The investigations of the axonal endings of the neuromuscular junctions in the soleus muscle showed diminution of the mean number of synaptic vesicles and swelling of the mitochondria. This changing in the fibres and axonal endings we can interpret as the first step of degeneration.
该研究旨在对乘坐“生物卫星936号”进行太空飞行后的动物比目鱼肌中的肌纤维和神经肌肉接头的轴突末梢进行定量和定性评估。对肌纤维的超微结构形态计量学研究表明，肌节体积减小，糖原颗粒积聚。线粒体轮廓的平均数量减少。对比目鱼肌神经肌肉接头轴突末梢的研究显示，突触小泡的平均数量减少，线粒体肿胀。我们可以将纤维和轴突末梢的这种变化解释为退化的第一步。
