STUDIES ON THE INFLUENCE OF SEASON AND LOW TEMPERATURE ON ATPase ACTIVITY OF Bufo gargarizans MUSCULAR TISSUE
季节及人工低温对大蟾蜍肌组织ATP酶的影响研究

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.
