Abstract

Histochemical investigation of rat skeletal muscle samples removed immediately post mortem from exercised rats gave the following results: (1) Of the oxidoreductase enzymes studied, there was a slight increase in the activity of cytochrome oxidase. (2) There was no change in the acid- and alkali-stable actomyosin ATPase activity. (3) There was a notable decrease in glycogen concentration. In the case of strychnine intoxication: (1) There was no change in oxidoreductase enzymes. (2) There was an increase in the activity of alkali-stable ATPase in white fibres. (3) The glycogen concentration notably decreased. There was no change in the activity of enzymes studied in those animals sacrificed by anoxia.

摘要

对刚处死的运动大鼠的骨骼肌样本进行组织化学研究，结果如下：(1)在所研究的氧化还原酶中，细胞色素氧化酶的活性略有增加。(2)酸碱稳定的肌动球蛋白ATP酶活性没有变化。(3)糖原浓度显著降低。在士的宁中毒的情况下：(1)氧化还原酶没有变化。(2)白肌纤维中碱稳定ATP酶的活性增加。(3)糖原浓度显著降低。在缺氧处死的动物中，所研究的酶的活性没有变化。
