In the rat, a circadian rhythm can be demonstrated in plasma levels and in urinary excretion rates of aldosterone and of corticosterone, reflecting rhythmic variations in adrenocortical secretion. There is also a circadian rhythm in the urinary excretion rates of sodium and of potassium in rats with unrestricted food consumption. The rhythmic pattern of potassium excretion seems to be controlled by the rhythm of corticosterone and/or aldosterone, whereas the rhythmic pattern of sodium excretion seems to be independent of adrenocortical secretion.
在大鼠中，醛固酮和皮质酮的血浆水平及尿排泄率可呈现昼夜节律，这反映了肾上腺皮质分泌的节律性变化。在食物摄入不受限制的大鼠中，钠和钾的尿排泄率也存在昼夜节律。钾排泄的节律模式似乎受皮质酮和/或醛固酮节律的控制，而钠排泄的节律模式似乎独立于肾上腺皮质分泌。
