Abstract
In light-dark-synchronized male rats the levels of noradrenaline in heart atria were about 3 times that found in heart ventricles. Noradrenaline turnover rate which were about 8-9 fold greater for the atria than for the ventricles displayed a circadian-phase-dependency with increased rates in the dark period in both parts of the rat heart.
摘要
在明暗同步的雄性大鼠中，心房中的去甲肾上腺素水平约为心室中的3倍。心房的去甲肾上腺素周转率比心室大约高8 - 9倍，且在大鼠心脏的两个部位均呈现昼夜节律依赖性，在黑暗期周转率增加。
