The uptake of 45Ca by the rabbit lens reached equilibrium within 20 hr; the steady state lens/medium ratio was 0.08. This ratio is similar to that found for the lens/medium distribution of extracellular markers. Efflux of 45Ca from the lens was rapid and insensitive to iodoacetate. Mathematical analysis of 45Ca efflux curves revealed that calcium efflux from the lens could be described solely upon the basis of passive movement from the extracellular space. It is concluded that the exchangeable calcium in the normal rabbit lens is predominantly located in the extracellular space.
兔晶状体对45Ca的摄取在20小时内达到平衡；稳态下晶状体/培养基的比值为0.08。该比值与细胞外标志物在晶状体/培养基中的分布情况相似。45Ca从晶状体的流出很快，且对碘乙酸不敏感。对45Ca流出曲线的数学分析表明，晶状体中钙的流出仅可基于从细胞外空间的被动移动来描述。得出的结论是，正常兔晶状体中可交换钙主要位于细胞外空间。
