摘要
研究了不同温度对东方铃蟾和中华大蟾蜍肌组织中肌球蛋白钙激活ATP酶活性的影响。结果表明 ,从 1 6℃上升到 3 2℃ ,两种动物两种肌组织ATP酶活性均逐渐升高 ,但东方铃蟾ATP酶活性变化比中华大蟾蜍敏感 ;从 3 2℃上升到 4 4℃ ,ATP酶活性均下降 ,但东方铃蟾ATP酶活性变化比中华大蟾蜍更敏感 ;ATP酶活性的最适温度在 3 2℃。ATP酶活性可能与这两种动物的入眠。
This paper deals with effects of the different temperature on the myosin Ca ++ -ATPase activity of various musclar tissues of Bombina orientalis and Bufo gargarzians. The results indicated that the ATPase activity of both animals was going up with the ascent of temperature from 16～32℃,but the change of ATPase activity of Bombina orientalis was more sensitive to the temperature increase than that of Bufo gargarzians. The ATPase activity was going down with the ascent of temperature from 32～44℃,but the change of ATPase activity of Bombina orientalis was much more sensitive than that of Bufo gargarzians. The optimum temperature for the ATPase of both animals was 32℃.The ATPase activity has probable relation to the time of hibernation,the time of emergence and heat hardiness.
