| 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) |
| iodine radioisotopes | Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes. (12 Dec 1998) |
| iodine reaction of epinephrine | A reaction resulting from the oxidation of the hormone, a faint pink colour appearing upon the addition of iodine. (05 Mar 2000) |
| iodine stain | <technique> A stain to detect amyloid, cellulose, chitin, starch, carotenes, and glycogen, and to stain amoebas by virtue of their glycogen; faeces and other wet preparations are stained directly with Lugol's iodine solution; smears are treated with Schaudinn's fixative and then stained with alcoholic iodine, followed by Heidenhain's iron haematoxylin. (05 Mar 2000) |
| iodine test | A test for detecting the presence of starch based on its reaction with iodine. (05 Mar 2000) |
| iodine tincture | A hydroalcoholic solution containing 2% elemental iodine and 2.4% potassium iodide to facilitate dissolution and 47% alcohol; used as an antiseptic/germicide on the skin surface for cuts and scratches. Has been used as a skin disinfectant before surgery but is now largely replaced by organic forms of iodine. (05 Mar 2000) |
| iodine uptake test | A test of thyroid function in which 131I-iodide is given orally; after 24 hours, the amount present in the thyroid gland is measured and compared with normal values. Synonym: radioactive iodide uptake test, RAI test. (05 Mar 2000) |
| iodine value | 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) |
| tamed iodine | A combination of iodine with a surfactant carrier, usually polyvinylpyrrolidone. Commercial preparations generally contain 1% "available" iodine, which is slowly released to take effect against microorganisms; used as skin disinfectants, particularly for surgical scrubs. Synonym: tamed iodine. Origin: iodine + G. Phora, a carrying (05 Mar 2000) |
| undecoylium chloride-iodine | A complex of iodine with undecoylium chloride; a cationic detergent used topically as a germicidal agent. (05 Mar 2000) |
| Lugol's iodine solution | An iodine-potassium iodide solution used as an oxidizing agent, for removal of mercurial fixation artifacts, and also in histochemistry and to stain amoebas. (05 Mar 2000) |
