Abstract
Distribution of ribonuclease activity (measured at pH 7.6) in subcellular fractions of homogenates of rat skeletal muscle was investigated in sedentary animals and after 8 weeks running program. Training increased ribonuclease activity (expressed as units of enzyme per g of muscle protein). There was no increase in nuclear fraction, but in both cytoplasmic and mitochondrial fractions the RNA-ase activity increased 42% and 45% respectively.
摘要
研究了久坐不动的大鼠和经过8周跑步训练后的大鼠骨骼肌匀浆亚细胞组分中核糖核酸酶活性（在pH 7.6条件下测定）的分布情况。训练增加了核糖核酸酶活性（以每克肌肉蛋白的酶单位表示）。细胞核组分中没有增加，但细胞质和线粒体组分中的核糖核酸酶活性分别增加了42%和45%。
