Calcium ion uptake into otoconia and bone mineral of the young adult rat was studied by use of 45Ca and liquid scintillation spectrometry. Results showed that saccular and utricular otoconia take up 45Ca in a time course generally comparable to bone but on a much lower scale. Saccular otoconia showed greater uptake than utricular. The results are interpreted to indicate the dynamic nature of saccular and utricular otoconia and their possible importance in preserving ionic homeostasis of the inferior and superior parts of the labyrinth, respectively.
利用45Ca和液体闪烁光谱法研究了成年幼鼠耳石和骨矿物质对钙离子的摄取情况。结果表明,球囊和椭圆囊耳石摄取45Ca的时间进程总体上与骨骼相当,但规模要小得多。球囊耳石的摄取量高于椭圆囊。这些结果被解释为表明球囊和椭圆囊耳石具有动态性质,以及它们分别在维持迷路上下部分离子稳态方面可能具有的重要性。
