The details of calcium flux during growth were examined in female rats. Twenty-eight 53-d-old rats were equally divided into 4 groups. Rats were given a purified diet (0.5% Ca and 0.35% Pi) throughout the experiment. Calcium balance and 45Ca kinetics studies using an open two-compartment model were performed over a 3-d period when rats were 60 (control), 74 , 88 and 116 d old. A simple calcium ...
