This work describes the results of investigations on whole body discrimination of 133Ba as compared to 85Sr and discrimination in specific portions of long bones. The examinations, conducted in two groups of rabbits young and adult ones, were aimed at determination whether the discrimination of heavy alkaline earth element 133Ba is greater or smaller in young rabbits than in adults ones. It was found that whole body discrimination of 133Ba, as well as the discrimination in specific portions of bones, is greater in young than in adult animals. The study shows, therefore, that the discrimination predominates in the addition process, i.e. in the process of formation of new bone mineral, and is not predominating in the process of augmentation, i.e. in slow ion exchange in compact bone material. This conclusion was based on the fact that in young animals addition is a much more active process than in adults.
这项工作描述了与85Sr相比，对133Ba进行全身鉴别以及对长骨特定部位进行鉴别的研究结果。在两组兔子（幼兔和成年兔）身上进行的检查旨在确定幼兔对重碱土元素133Ba的鉴别能力是大于还是小于成年兔。结果发现，幼兔对133Ba的全身鉴别以及对骨骼特定部位的鉴别能力均强于成年动物。因此，该研究表明，这种鉴别在新增过程中占主导地位，即在新骨矿物质形成过程中占主导地位，而在增强过程中不占主导地位，即在致密骨材料中的缓慢离子交换过程中不占主导地位。这一结论基于以下事实：在幼小动物中，新增过程比成年动物更为活跃。
