Effects of orally administered vanadium on the immune system and bone metabolism in experimental animals.

Experiments were carried out to gain more information on the effects of long term exposure to low doses of vanadium administered to mice and rats in drinking water. The selective immunotoxic effects of vanadium were depression of phagocytosis, splenotoxicity, enlargement of spleen, elevation of peripheral blood leucocytes and T and B cell activation. Vanadium accumulates in hard tissues and influences the mineralisation of epiphyseal cartilage.
