1. 用 45Ca 标记豚鼠耳廓以及绵羊和小牛心脏心室小梁中的可交换 Ca,并测量不同离子成分的非活性冲洗溶液中放射性损失长达 6 小时。肌肉中放射性的下降在任何时候都不会遵循单一指数过程,而速率系数 k(= 每分钟从肌肉进入冲洗溶液的 45Ca 损失分数)随时间略有下降。
1. Exchangeable Ca in guinea‐pig auricles and ventricular trabeculae of sheep and calf hearts was labelled with 45Ca and the loss of radioactivity into inactive rinsing solutions of different ion composition was measured for periods up to 6 hr. At no time did the decrease of radioactivity in the muscle follow a single exponential course, while the rate coefficient k (= fraction of 45Ca lost per minute from muscle into rinsing solution) decreased slightly with time.
