The activity of synaptosomal Mg- and Na, K-ATPases has been compared during natural hibernation and active periods in ground squirrels. Being assayed in vitro at temperature 37 degrees, the activity of Na, K-ATPase decreases during hibernation by 25%, that of Mg-ATPase--by 37%. The decreased level of the activity of these enzymic systems may result from structural alterations in the brain membranes during hibernation of the animals.
对冬眠地松鼠和活跃期地松鼠的突触体镁 - 三磷酸腺苷酶(Mg - ATPase)以及钠钾 - 三磷酸腺苷酶(Na, K - ATPase)的活性进行了比较。在37摄氏度下体外测定时,冬眠期间Na, K - ATPase的活性下降了25%,Mg - ATPase的活性下降了37%。这些酶系统活性水平的降低可能是由于动物冬眠期间脑膜的结构改变所致。
