In the Cosmos biosputnik 1514, 1667, 1887, 2044 and 1129 the rats 5, 7, 12,5, 15, 18,5 days were in weightlessness state. Due to the adaptation of the skeletal muscles' weightlessness the adaptation was different in various muscles, which depends on the time of participation in antigravitation, the composition of the fibers and from the biometrical characteristics. In different muscles, the changing of the metabolism and the structure of the muscles more than likely in connection with the changing of the myosin subordinate unit compositions. In our experiments we had studied, as to how the muscular atrophy changes, does it increase all the time, or does it balances out after reaching a certain stage.
在宇宙生物卫星1514、1667、1887、2044和1129号中,大鼠分别处于5、7、12.5、15、18.5天的失重状态。由于骨骼肌对失重的适应,不同肌肉的适应情况不同,这取决于参与抗重力作用的时间、纤维组成以及生物测量特征。在不同肌肉中,肌肉代谢和结构的变化很可能与肌球蛋白亚单位组成的变化有关。在我们的实验中,我们研究了肌肉萎缩是如何变化的,是一直增加,还是在达到某个阶段后趋于平衡。
