Measurements of body sodium content in rats were made in vivo by either neutron activation analysis or the use of the radioisotope, 22Na. The results were compared with estimates of TBNa of the carcases. Neutron activation analysis provided an accurate measure of total body sodium content. NaE, measured with 22Na, was consistently and quantitatively lower than total body sodium content. Each of these methods may be useful in the study of body sodium content in small animals during growth and during the evolution of experimental hypertension.
通过中子活化分析或使用放射性同位素22Na对大鼠体内的身体钠含量进行了测量。将结果与 carcasses 的总身体钠（TBNa）估计值进行了比较。中子活化分析提供了全身钠含量的准确测量。用22Na测量的NaE始终且定量地低于全身钠含量。这些方法中的每一种在研究小动物生长期间和实验性高血压发展过程中的身体钠含量时可能都有用。
