Examinations of 37 rats flow for 22 days onboard the biosatellite Cosmos-605 revealed no changes in the mineralization coefficient or the Ca and P content in humerus and teeth of the animals on the 2nd and 26th postflight days. Radioisotope studies showed changes in the specific activity of Ca45 incorporation in humerus and incisors. In flight rats the parameter decreased by 37-44%, in synchroneous animals it increased by 102% in bones and by 20% in incisors as compared with the vivarium controls on the 2nd postflight day. The specific activity of Ca45 incorporation was 92.7% in humerus and 44.2% in incisors of flight rats and 72.9% in humerus and 94.7% in incisors of synchroneous rats as compared with the vivarium controls on the 26th postflight day.
对搭载在生物卫星“宇宙-605”号上飞行22天的37只大鼠进行检查发现，在飞行后第2天和第26天，动物肱骨和牙齿中的矿化系数以及钙和磷含量没有变化。放射性同位素研究表明，钙45掺入肱骨和门齿的比活性发生了变化。与飞行后第2天的饲养对照相比，飞行大鼠的该参数下降了37-44%，同步动物的骨骼中该参数增加了102%，门齿中增加了20%。与飞行后第26天的饲养对照相比，飞行大鼠肱骨中钙45掺入的比活性为92.7%，门齿中为44.2%；同步大鼠肱骨中为72.9%，门齿中为94.7%。
