摘　　要：本文研究了大蟾蜍心肌和腓肠肌肌球蛋白钙激活ATP酶的活性。实验结果显示,大蟾蜍心肌和腓肠肌肌球蛋白钙激话ATP酶活性具有不同的季节变化规律。并且这种酶活性的季节变化不受人工低温环境因素的影响。此外,大蜍蟾心肌中ATP酶的活性始终高于腓肠肌的。上述酶活性的变化均具有一定的生理意义。This paper studies the myosin Ca++-ATPase activity of Bufo gargarizans cardiac muscles and gastrocnemius muscles. The experimental results imply that the changes of myosin Ca++-ATPase activity of B. gargarizans cardiac muscles and gastrocnemius muscles take place depending on the active law of theirs in different season, and artifical low temperature has no effect on above changes. In addition, the myosin Ca++-ATPasc activity of cardiac muscles is consistently higher than of gastrocnemius muscles in different season. These changes of Ca++-ATPase activity are important for physiological actions.
