Description/Abstract:

IN PREVIOUS STUDIES CONCERNED WITH BIOLOGIC DECAY PERIODS FOR THE RADIOACTIVE ISOTOPE OF SODIUM, IT BECAME NECESSARY TO ENTER INTO THEORETIC CONSIDERATIONS OF RATES OF CHANGE IN CONCENTRATION OF THE ISOTOPE IN THE BODY FLUIDS AND IN OTHER COMPARTMENTS AS WELL AS RATES OF ELIMINATION. EQUATIONS WERE DERIVED WHICH MAKE IT POSSIBLE TO PREDICT THE INFLUENCE OF INTAKE AND OUTPUT VARIATIONS OF A NONTRACER SUBSTANCE AND OF THE SIZE OF ITS COMPARTMENT UPON THE CONCENTRATION WITHIN THE ORGANISM, AND ELIMINATION FROM THE ORGANISM OF A TRACER SUBSTANCE ADMINISTERED IN A SINGLE DOSE. RESULTS OBTAINED AND CONCEPTS DEVELOPED ARE WORTHY OF REPORTING BECAUSE OF THEIR GENERAL APPLICATION TO BIOLOGIC AND OTHER TRACER EXPERIMENTS.
