The aim of the present study was to estimate the concentration of Mg, Zn, Cu in the following tissues: heart, lung, brain, liver, kidney and femoral muscles in conditions of experimentally induced hyperthyreosis. In general instate of hyperthyreosis the concentration of all elements was considerably higher compared to euthyreosis. However there are a few exceptions. Liver tissue possesed high er concentration of Zn and Cu and kidney of Cu in euthyreosis.
