On the R+O day the quadriceps muscle of rats showed a decrease in the content of T protein and an inhibition of LDH activity of sacroplasmatic proteins. These changes resulted from the combined affect of space flight factors and gamma-irradiation, and may be considered as a decline of compensatory synthetic processes responsible for the recovery of muscle proteins in weightlessness. Inhibition of the age-associated shift of the M:H ratio of LDH found on the R+25 day can be attributed to the inhibitory effect of gamma-irradiation. No change in the content of glycogen in the gastrocnemius muscle of flight rats was noted.
在“恢复+照射”日，大鼠股四头肌的T蛋白含量降低，肌浆蛋白的乳酸脱氢酶（LDH）活性受到抑制。这些变化是太空飞行因素和γ射线辐射共同作用的结果，可被视为负责肌肉蛋白在失重状态下恢复的代偿性合成过程的衰退。在“恢复+25”日发现的与年龄相关的LDH的M:H比值变化受到抑制，这可归因于γ射线辐射的抑制作用。未观察到飞行大鼠腓肠肌中糖原含量的变化。
