| polyvinylpyrrolidone-iodine complex | <chemical> A water soluble complex of iodine with polyvinylpyrrolidone. Applied as an antiseptic in the form of solutions or ointments, it releases iodine. Used in cleansing and disinfecting the skin, preparing the skin preoperatively, and treating infections susceptible to iodine. 1-ethenyl-2-pyrrolidone homopolymer complexed with iodine. An iodinated polyvinyl polymer used as topical antiseptic in surgery and for skin and mucous membrane infections, also as aerosol. The iodine may be radiolabelled for research purposes. Synonym: polyvinylpyrrolidone-iodine complex, povidone-iodine. Pharmacological action: anti-infective agents, local, iodophors. Chemical name: 2-Pyrrolidinone, 1-ethenyl-, homopolymer, compd. With iodine (20 Sep 2002) |

| protein-bound iodine | Thyroid hormone in its circulating form, consisting of one or more of the iodothyronines bound to one or more of the serum proteins. (05 Mar 2000) |
| protein-bound iodine test | A formerly used test of thyroid function in which serum protein-bound iodine is measured to provide an estimate of hormone bound to protein in peripheral blood. Synonym: PBI test. (05 Mar 2000) |
| sodium iodide iodine-131 | Prepared from radioactive iodine (131I); practically carrier-free, with a half-life of 8.0 days; used as a diagnostic agent in suspected thyroid disease and in the treatment of selected thyroid diseases. (05 Mar 2000) |
| starch-iodine test | A test for sweating in which iodine in oil is painted on the skin, followed by dusting with a starch powder which turns blue-black in the presence of iodine and moisture. (05 Mar 2000) |
| diglycocoll hydroiodide-iodine | Two moles of diglycocoll hydroiodide combined with two atomic weights of iodine; an antibacterial agent used in tablet form to disinfect drinking water. (05 Mar 2000) |
| iodine | <element> An element. Radiation therapy often uses radioactive forms of iodine in treatment. (13 Nov 1997) |
| iodine-123 | <radiobiology> A radioisotope of iodine with a 159 keV gamma emission and a physical half-life of 13.2 hr, frequently used for studies of thyroid disease and of renal function. (05 Mar 2000) |
| iodine-125 | <radiobiology> Radioactive iodine isotope that decays by K-capture (internal conversion) with a half-life of 59.4 days; used as a tracer in thyroid studies and as a label in immunoassay and in imaging. (05 Mar 2000) |
| iodine-127 | <radiobiology> Stable, nonradioactive iodine, the most abundant iodide isotope found in nature; dietary deficiency causes simple goiter; used to block thyroid uptake of radioactive iodine released from nuclear accidents. (05 Mar 2000) |
| iodine-131 | <radiobiology> A radioactive iodine isotope, 364 keV peak beta and gamma emitter with a half-life of 8 days. It is used as a tracer in thyroid studies, as therapy in hyperthyroidism, thyroid cancer, and heart disease, and as a label in immunoassay and imaging. (22 Sep 2002) |
| iodine-132 | <radiobiology> A beta-and gamma-emitting radioisotope of iodine with a physical half-life of 2.28 hr, usually obtained from a tellurium-132 radionuclide generator; its clinical use has been supplanted by 131I and 123I. (05 Mar 2000) |
