| tenth-value layer | <radiobiology> Thickness of a specified substance which, when introduced into the path of a given beam of radiation, reduces the absorbed dose index or dose-equivalent index to one-tenth. The magnitude of the tenth-value layer may be different for absorbed dose index and dose equivalent index. (16 Dec 1997) |
|---|---|
| thiocyanogen value | The number of grams of thiocyanogen taken up by 100 g of fat; analogous to the iodine number, except that thiocyanogen will not add to all the double bonds in polyunsaturated fatty acids as will iodine. Synonym: thiocyanogen value. (05 Mar 2000) |
| threshold limit value | The maximum concentration of a chemical recommended by the American Conference of Government Industrial Hygienists for repeated exposure without adverse health effects on workers. (05 Mar 2000) |
| economic value of life | The evaluation of the monetary value of a life lost or a life saved. (12 Dec 1998) |
| law of initial value | The direction of response of a body function to any agent depends to a large degree on the initial level of that function. Synonym: law of initial value. (05 Mar 2000) |
| lower heating value | (LHV) The potential energy in a fuel if the water vapour from combustion of hydrogen is not condensed. (05 Dec 1998) |
| butanol-extractable iodine | Iodine that can be separated from plasma proteins by butanol or other extractable solvents; used to measure thyroid function. (05 Mar 2000) |
| butanol-extractable iodine test | An obsolete test for thyroid function, applicable in patients who have received large amounts of iodine or iodised products. Synonym: BEI test. (05 Mar 2000) |

| Mallory's iodine stain | <technique> Amyloid appears red-brown after Gram's iodine, then violet and blue after flooding with dilute sulfuric acid. (05 Mar 2000) |
| caseo-iodine | casein iodine |
| Gram's iodine | <microbiology> A solution containing iodine and potassium iodide, used in Gram's stain. (05 Mar 2000) |
| Weigert's iodine solution | An iodine-potassium iodide mixture used as a reagent to alter crystal and methyl violet so that they are retained by certain bacteria and fungi. (05 Mar 2000) |
| 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) |
