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

/va·na·di·um/ (vah-na´de-um) a chemical element, at. no. 23, symbol V. 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.

vanadium (V)

[vənā′dē·əm]
Etymology: ONorse, Vanadis, Freya, goddess of fertility
a grayish metallic element. Its atomic number is 23; its atomic mass is 50.942. Absorption of vanadium compounds results in a condition called vanadiumism, characterized by anemia, conjunctivitis, pneumonitis, and irritation of the respiratory tract.

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.

vanadium (v·nāˑ·dē·m),

n an element/mineral thought by some to be essential for health. Has been used for its antidiabetic properties. Vanadium is toxic (nephrotoxic, hepatotoxic, and teratogenic) in excess and can accumulate in tissues. Caution is advised for patients with severe kidney or liver conditions and for those taking antidiabetic medications. Also called
vanadyl sulfate or
vanadate.

vanadium poisoning
in humans poisoning is usually by inhalation causing respiratory irritation and pneumonia. In livestock poisoning is by ingestion of contaminated pasture and manifested by diarrhea, incoordination and oliguria.
