| 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 | 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 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) |
| a granules | Large, rodlike, or filamentous granules found in several types of cells, especially platelets where they are the most numerous type of granule; contain secretory proteins, including fibrinogen, fibronectin, fibrospondin, von Willebrand factor (collectively known as adhesive proteins) and other proteins (platelet factor 4, platelet-derived growth factor, coagulation factor V, etc.). (05 Mar 2000) |
| argentaffin granules | Granule's that reduce silver ions from an ammoniacal silver nitrate staining solution. (05 Mar 2000) |
| Bensley's specific granules | Granule's in the cells of the islands of Langerhans in the pancreas. (05 Mar 2000) |
| Bollinger granules | Relatively small, but frequently microscopically visible, pale yellow or yellow-white granule's observed in the granulomatous lesion, or the exudate, in botryomycosis; the granule's consist of irregular aggregates or colonizations of Gram-positive cocci, usually staphylococci, term sometimes incorrectly used synonymously with Bollinger bodies. (05 Mar 2000) |
| volutin granules | A nucleoprotein complex found as cytoplasmic granules in certain bacteria, yeasts, and protozoa (such as trypanosome flagellates) which serves as food reserves. Synonym: volutin granules. (05 Mar 2000) |
| chromaffin granules | Granules in the adrenal glands and various other organs, which are concerned with the synthesis, storage, metabolism, and secretion of epinephrine and norepinephrine. (12 Dec 1998) |
| chromophobe granules | Granule's that do not stain or stain poorly with the ordinary dyes; such granule's are present in some cells in the anterior lobe of the pituitary. (05 Mar 2000) |
| mucinogen granules | Granule's that produce mucin, as in cells of the salivary glands and in the gastric and intestinal mucosae. (05 Mar 2000) |
| Crooke's granules | Lumpy masses of basophilic material in the basophil cells of the anterior lobe of the pituitary, associated with Cushing's disease, or following the administration of ACTH. (05 Mar 2000) |
| cytoplasmic granules | Stored products of a cell's metabolic activity. (12 Dec 1998) |
