The active calcium transport along the small intestine of adult rat was shown to exhibit daily rhythmic variations of considerable amplitude. Both the light-dark cycle and the time of food presentation acted as synchronizers of the rhythm observed.
成年大鼠小肠中活跃的钙转运表现出幅度相当大的每日节律变化。明暗周期和食物投喂时间均作为所观察到的节律的同步器。
