Concentrations of selenium and rubidium in groups of subjects with hyperthyroidism, carcinomas, or adenomas and in controls were determined by neutron activation analysis with coirradiated inorganic standards and IAEA reference material. Se was decreased in all pathological groups with the greatest modification in thyroids with carcinomas. Rb was elevated in all pathological groups with the greatest increase in carcinomas as well. According to the literature, Se has a protective effect on carcinogenity as well as on biochemical pathways in thyroid cells. There are no data in the literature on the effects of Rb in those cells. On the grounds of the present results, it seems possible to use the trapping of Rb for diagnostic purposes in cases of pathologically altered thyroids.
