| iodimetry | Synonym: iodometry. Origin: iodine + G. Metron, measure (05 Mar 2000) |

| iodinase | <enzyme> A haemprotein that catalyses the oxidation of the iodide radical to iodine with the subsequent iodination of many organic compounds, particularly proteins. Chemical name: Iodide:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.8 (12 Dec 1998) |
| iodinate | To treat or combine with iodine. (05 Mar 2000) |
| iodinated 125I serum albumin | A sterile, buffered, isotonic solution prepared to contain not less than 10 mg of radioiodinated normal human serum albumin per ml, and adjusted to provide not more than 1 mCi of radioactivity per ml; used as a diagnostic aid in determining blood volume and cardiac output. Synonym: radioiodinated serum albumin. (05 Mar 2000) |
| iodinated 131I human serum albumin | A sterile, buffered, isotonic solution prepared to contain not less than 10 mg of radioiodinated normal human serum albumin per ml, and adjusted to provide not more than 1 mCi of radioactivity per ml; used as a diagnostic aid in the measurement of blood volume and cardiac output. (05 Mar 2000) |
| iodinated contrast | A substance that contains iodine that can be injected, swallowed or given as an enema for the purpose of diagnostics. Iodinated contrast is radiopaque. This means that conventional X-rays will highlight the course of the contrast in the body. (27 Sep 1997) |
| iodinated contrast material | A substance that contains iodine that can be injected, swallowed or given as an enema for the purpose of diagnostics. Iodinated contrast is radiopaque. This means that conventional X-rays will highlight the course of the contrast in the body. (27 Sep 1997) |
| iodinated glycerol | A form of organically bound iodine which liberates iodine systemically. Has been used as a medicinal source of iodine and as an expectorant in place of inorganic iodides such as potassium iodide. Synonym: iodopropylidene glycerol, organidin. (05 Mar 2000) |
| iodine | <element> An element. Radiation therapy often uses radioactive forms of iodine in treatment. (13 Nov 1997) |
| iodine compounds | Inorganic compounds that contain iodine as an integral part of the molecule. (12 Dec 1998) |
| iodine cysts | An obsolete term used to indicate the cyst's of Iodamoeba butschlii, characterised by a large iodine-positive glycogen vacuole. (05 Mar 2000) |
| 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). For example, 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 to severe iodine deficiency, goiter, and hypothyroidism. Since the addition of iodine to table salt, iodine deficiency is rarely seen in the united states. (12 Dec 1998) |
| iodine excess | Just as too little iodine can cause thyroid disease, so may prolonged intake of too much iodine also 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). (12 Dec 1998) |
| iodine isotopes | Stable iodine atoms that have the same atomic number as the element iodine, but differ in atomic weight. I-127 is the only naturally occurring stable iodine isotope. (12 Dec 1998) |
| iodine number | An indication of the quantity of unsaturated fatty acids present in a fat; it represents the number of grams of iodine absorbed by each 100 g of fat. See: hydrogen number. Synonym: iodine value. (05 Mar 2000) |
