| filling defect | Displacement of contrast medium by a space-occupying lesion in a radiographic study of a contrast-filled hollow viscus, such as a polyp on a barium enema; also applied to defects in the otherwise uniform distribution of radionuclide in an organ, such as a metastasis in the liver on a 99mTc-sulfur colloid scan. (05 Mar 2000) |
| filling defect in renal collecting system | <radiology> Common causes: transitional cell carcinoma, blood clot, lucent calculus (urate) less common causes: fungus ball, sloughed papilla, fibroepithelial polyp, invasion by hypernephroma, malakoplakia, vessel impression, metastases (12 Dec 1998) |
| 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) |
| colloidal silver iodide | An antiseptic used for treatment of inflammation of the mucous membranes. (05 Mar 2000) |
| silver | 1. <chemistry> A soft white metallic element, sonorous, ductile, very malleable, and capable of a high degree of polish. It is found native, and also combined with sulphur, arsenic, antimony, chlorine, etc, in the minerals argentite, proustite, pyrargyrite, ceragyrite, etc. Silver is one of the "noble" metals, so-called, not being easily oxidized, and is used for coin, jewelry, plate, and a great variety of articles. Symbol Ag (Argentum). Atomic weight 107.7. Specific gravity 10.5. Silver was known under the name of luna to the ancients and also to the alchemists. Some of its compounds, as the halogen salts, are remarkable for the effect of light upon them, and are used in photography. 2. Coin made of silver; silver money. 3. Anything having the luster or appearance of silver. 4. The colour of silver. Silver is used in the formation of many compounds of obvious meaning; as, silver-armed, silver-bright, silver-buskined, silver-coated, silver-footed, silver-haired, silver-headed, silver-mantled, silver-plated, silver-slippered, silver-sounding, silver-studded, silver-tongued, silver-white.
