Multitracer, a new tracer technique developed by us, can analyze metabolism and behavior of different elements in the living bodies simultaneously. We were able to reproduce completely the results on the behavior of various elements obtained by individual experiments of our precursors only by a single run of this technique. At the same time, we could also show the behavior and interaction of many other trace elements which past researchers did not pay attention too. For example, our results on the behavior of rare-earth elements suggested that there is a correlation between their uptakes and ion radii. We also discovered that affinities of platinum and iridium for their binding proteins were changed, the latter being increased, in the case of zinc deficiency. In this article, we discuss the usefulness of the multitracer technique in the studies of trace elements in living bodies.
