vanadium

 [vah-na´de-um]
a chemical element, atomic number 23, atomic weight 50.942, symbol V. (See Appendix 6.) Its salts have been used in treating various diseases. Absorption of its compounds, usually via the lungs, causes chronic intoxication, the symptoms of which include respiratory tract irritation, pneumonitis, conjunctivitis, and anemia.

va·na·di·um (V),

(vă-nā'dē-ŭm),
A metallic element, atomic no. 23, atomic wt. 50.9415; a bioelement, its deficiency can result in abnormal bone growth and a rise in cholesterol and triacylglycerol levels.

vanadium

A metallic element (atomic number 23; atomic weight 50.94) present in trace amounts in the environment, which has an uncertain role in humans. Some data suggest that vanadium may lower serum glucose; participate in cholesterol, triglyceride and bone metabolism and in hormone production; and possibly protect against cancer. Vanadium is present in fish, liver, nuts, root vegetables, vegetable oils and whole grains; a vanadium deficiency state is not known to exist in humans.
