Distributon of trace elements in organs of mice of different inbred strains

In eight organ systems of five different inbred strains of mice the concentrations of rubidium, zinc and iron were investigated. In the case of rubidium two of the inbred strains showed relatively low concentrations in all organ systems, whereas zinc and iron exhibited a rather irregular distribution within the eight organ systems. The differences in concentrations found in the various organs of the five inbred strains—especially the distribution pattern of rubidium—may allow further genetic experiments and thus help to elucidate the physiology and pathology of trace elements.
