| metachromatic | Denoting cells or dyes that exhibit metachromasia. Synonym: metachromophil, metachromophile. (05 Mar 2000) |
|---|---|
| metachromatic bodies | Concentrated deposits consisting primarily of polymetaphosphate and occurring in many bacteria as well as in algae, fungi, and protozoa; m. Body's differ in staining properties from the surrounding protoplasm. See: metachromasia. (05 Mar 2000) |
| metachromatic granules | Granule's that stain a colour different from that of the dye used. See: metachromasia. Term sometimes used as a synonym for volutin. (05 Mar 2000) |
| metachromatic leukodystrophy | <radiology> Dysmyelinating disease, autosomal recessive, aryl sulfatase A -- absent from urine and serum, most present by 2 yrs, die at 3-4 yrs, may arise at any age, CT: decreased density of white matter, primarily in centrum semiovale, with or without focal gall bladder defects (!) (12 Dec 1998) |
| metachromatic stain | <technique> A stain, such as methylene blue, thionin, or azure A, that has the ability to produce different colours with various histological or cytological structures. (05 Mar 2000) |
| leukodystrophy, metachromatic | A sphingolipidosis where there is defective desulfation of galactosyl-3-sulfate ceramide due to a defective enzyme cerebroside sulfatase (arylsulfatase a). The result is an accumulation of sulfatide in neural and non-neural tissues which manifests as mental deterioration and severe disturbances of the central nervous system. (12 Dec 1998) |
| azo dye | <chemistry> Dyes that contain the N=N linkage. They are easily prepared from diazo compounds. (18 Nov 1997) |
| radiopaque contrast dye | A radiopaque substance (for example metal) will be highlighted (appear white) on a plain X-ray. The use of iodine containing radiopaque contrast dyes allow enhancement of the anatomy demonstrable with conventional X-ray. (27 Sep 1997) |
| Motulsky dye reduction test | A test for glucose-6-phosphate dehydrogenase deficiency in the blood, using a mixture of brilliant cresyl blue, glucose-6-phosphate, and NADP. (05 Mar 2000) |
| Sabin-Feldman dye test | A method for the detection of anti-toxoplasma antibody in serum, based on the fact that Toxoplasma gondii cells (from peritoneal exudate in mice) are fairly well stained with alkaline methylene blue, whereas organisms in a serum that contains specific antibody have no affinity for the dye; furthermore, normal toxoplasma cells become rounded, and the nucleus and cytoplasm deeply stained, when treated with the methylene blue; on the other hand, when dye is mixed with organisms and antibody, the cells retain their crescent shape and only the shrunken nuclear endosome is stained. (05 Mar 2000) |
| salt dye | <technique> A compound of an acid stain and a basic stain, such as the eosinate of methylene blue, in which the anion and cation each contains a chromophore group. Synonym: salt dye. (05 Mar 2000) |
| nitro dye | <chemical> Dye's in which the chromophore is -NO2, which is so acidic that all dyes in this group are of the acid type; important examples in cytoplasmic staining are picric acid and naphthol yellow S. (05 Mar 2000) |
| dye | A stain or colouring matter; a compound consisting of chromophore and auxochrome groups attached to one or more benzene rings, its colour being due to the chromophore and its dyeing affinities to the auxochrome. Dyes are used for intravital colouration of living cells, staining tissues and microorganisms, as antiseptics and germicides, and some as stimulants of epithelial growth. For individual dye's, see the specific names. Commonly but improperly used for radiographic contrast medium. Origin: A.S. Deah, deag (05 Mar 2000) |
| dye-dilution curve | Graph of the serial concentrations (dilutions) of a dye, e.g., Evans blue, following its intravascular or intracardiac injection; useful in the diagnosis of congenital cardiac shunts, measurement of cardiac output, and detection of cardiovalvular incompetence. Synonym: indicator-dilution curve. (05 Mar 2000) |
| dye dilution technique | Method for assessing flow through a system by injection of a known quantity of dye into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
