(Modern Latin: 1. iodine. 2. the color violet)

1. The chemical form to which iodine in the diet is reduced before it is absorbed through the intestinal wall into the bloodstream and carried through the blood to the thyroid gland.
2. Dietary iodine is reduced to iodide, absorbed in the intestines, and later taken up from the bloodstream by the thyroid gland for incorporation into thyroid hormones.
To add iodine to a compound, usually in substitution for hydrogen, but sometimes by simple addition.
The process of treating a substance with, or causing it to combine with, iodine or with an iodine compound.
1. A nonmetallic element belonging to the halogens; used especially in medicine and photography and in dyes; and occurs naturally only in combination in small quantities (as in sea water or rocks).
2. A tincture consisting of a solution of iodine in ethyl alcohol; applied to wounds as an antiseptic.

iodine deficiency
Iodine is a natural requirement of our diets. Iodine deficiency can lead to inadequate production of thyroid hormone from the thyroid gland (hypothyroidism).

In some parts of Zaire, Ecuador, India, and Chile, remote, mountainous areas; such as, in the Alps (in the past), Andes and the Himalayas have a particular predisposition for severe iodine deficiency, goiter, and hypothyroidism.

Since the addition of iodine to table salt, iodine deficiency is rarely seen in the United States.

iodine excess
Just as too little iodine can cause thyroid disease, so may prolonged intake of too much iodine lead to the development of goiter (swelling of the thyroid gland) and hypothyroidism (abnormally low thyroid activity).

Certain foods and medications contain large amounts of iodine. Examples include seaweed; iodine-rich expectorants (such as SSKI and Lugol's solution) used in the treatment of cough, asthma, chronic pulmonary disease; and amiodarone (CARDORONE), an iodine-rich medication used in the control of abnormal heart rhythms (cardiac arrhythmias).

iodinometry, iodometry
The quantitative measurement of iodine, either as a constituent of a mixture or compound or as released from an iodide after oxidation.
Readily combining with or staining with iodine.
Poisoning from th chronic ingestion of iodine or its compounds, or from intensive, repeated therapy.
1. To treat with iodine and to incorporate or attach (iodine) to a product.
2. To administer or to impregnate with iodine.
iodized salt, iodised salt (British)
Table salt mixed with a minute amount of sodium iodide or iodate, with the purpose of helping to reduce the chance of iodine deficiency in humans.

Iodine deficiency commonly leads to thyroid gland problems, specifically goiter, or an abnormally enlarged thyroid gland which may result from under-production, or over-production, of hormone or from a deficiency of iodine in the diet.

A cutaneous lesion resulting from an adverse reaction to ingested iodine.
A compound containing approximately 96% iodine.

It is a yellow, crystalline powder and it is used topically as an anti-infective agent.

Poisoning from iodoform.

Topical application of large quantities has produced inflammation of the brain or cord and fatty degeneration of internal organs.

Roentgenography, or radiographic visualization, of an organ or body part after being injected with an iodized oil.
