| iodate | <chemistry> A salt of iodic acid. Source: Websters Dictionary (01 Mar 1998) |
| iodate reaction of epinephrine | A reaction dependent upon the oxidation of epinephrine by iodine liberated from iodate, which is decomposed by the hormone; a faint pink colour results. (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
| Masson-Fontana ammoniacal silver stain | <technique> A stain used to demonstrate melanin and argentaffin granules. Synonym: Fontana-Masson silver stain. (05 Mar 2000) |
| rep-silver | Money anciently paid by servile tenants to their lord, in lieu of the customary service of reaping his corn or grain. See: Reap. Source: Websters Dictionary (01 Mar 1998) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Gomori's methenamine-silver stain | <technique> Techniques for 1) argentaffin cells: a method using a methenamine-silver solution in combination with gold chloride, sodium thiosulphate, and safranin O; argentaffin granules appear brown-black against a green background; 2) urates: warm sections are treated directly with a hot methenamine-silver solution to produce a blackening of urates; 3) fungi: see Grocott-Gomori methenamine-silver stain; 4) melanin, which reduces silver nitrate. (05 Mar 2000) |
| Gomori's silver impregnation stain | <technique> A reliable method for reticulin, as an aid in the diagnosis of neoplasm and early cirrhosis of the liver; the staining solution employs silver nitrate, potassium hydroxide, and ammonia water carefully prepared to avoid having silver precipitate. (05 Mar 2000) |
| Grocott-Gomori methenamine-silver stain | <technique> A modification of Gomori's methenamine-silver stain for fungi in which sections are pretreated with chromic acid before addition of the methenamine-silver solution and then counterstained with light green to demonstrate black-brown fungi against a pale green background. (05 Mar 2000) |
| methenamine-silver | A hexamethylenetetramine-silver complex prepared by adding silver nitrate to methenamine; a white precipitate appears in the solution which dissolves upon shaking and is stable under refrigeration; used in various histological and histochemical staining methods. See: Gomori's methenamine-silver stain. (05 Mar 2000) |
| mild silver protein | A complex prepared by the reaction of silver oxide with either gelatin or serum albumin. Black shiny crystals liberate silver and it was formerly widely used as a topical anti-infective on mucous membranes. Contains from 19 to 25% silver, only a small fraction of which is ionizable. Can produce black or brown pigmentation due to deposition of reduced silver in the tissues. Synonym: argyrol, silvol. (05 Mar 2000) |
| Warthin-Starry silver stain | <technique> A stain for spirochetes in which preparations are incubated in 1% silver nitrate solution followed by a developer. (05 Mar 2000) |
