sil·ver stain

any of a variety of stains (for example, Bielschowsky, Gomori silver, impregnation stains) that employ alkaline silver nitrate solutions to stain connective tissue fibers (reticulin, collagen), calcium salt deposits, spirochetes, neurologic tissue, and nucleolar organizer regions.
A metallic silver-based stain which is used to highlight basement membranes, and is of greatest use in glomerulonephritides, many of which have thickening or other glomerular basement membrane changes

silver

1. a chemical element, atomic number 47, atomic weight 107.870, symbol Ag. See Table 6. It is used in medicine for its caustic, astringent and antiseptic effects. Experimental poisoning with silver salts causes myopathy.

silver nitrate (toughened)
a mixture of silver nitrate with hydrochloric acid, sodium chloride or potassium nitrate, occurring as white crystalline masses molded into pencils or cones, called caustic pencils; a convenient means of applying silver nitrate locally. Called also lunar caustic.
silver protein
silver made colloidal by the presence of, or combination with, protein; an active germicide with a local irritant and astringent effect.
silver stain
a method of demonstrating flagella on bacteria, or for visualizing very thin bacteria, such as leptospires.
silver sulfadiazine
the silver salt of sulfadiazine, having bactericidal activity against many gram-positive and gram-negative organisms, as well as being effective against yeasts; used as a topical anti-infective for the prevention and treatment of wound sepsis in patients with second and third degree burns.
