| palladium | <chemistry> A rare metallic element of the light platinum group, found native, and also alloyed with platinum and gold. It is a silver-white metal resembling platinum, and like it permanent and untarnished in the air, but is more easily fusible. It is unique in its power of occluding hydrogen, which it does to the extent of nearly a thousand volumes, forming the alloy Pd2H. It is used for graduated circles and verniers, for plating certain silver goods, and somewhat in dentistry. It was so named in 1804 by Wollaston from the asteroid Pallas, which was discovered in 1802. Symbol Pd. Atomic weight.2. Source: Websters Dictionary (01 Mar 1998) |
| silver-ammoniacal silver stain | <technique> A stain for the acid protein component of nucleolar regions which are active or which were transcriptionally active in the preceding interphase; uses silver nitrate, ammoniacal silver, and formalin. Synonym: Ag-AS stain. (05 Mar 2000) |
| alloy | <chemistry> A substance made from a mixture of a metal and one or more other metals or non-metallic elements. (09 Oct 1997) |
| Raney alloy | An alloy of Ni and Al in equal proportions, used in the preparation of Raney Nickel. (05 Mar 2000) |
| gold alloy | An alloy whose principal ingredient is gold, usually contains copper or platinum and silver; used in dentistry for restorations requiring considerable strength. (05 Mar 2000) |
| eutectic alloy | An alloy, generally brittle and subject to tarnish and corrosion, with a fusion temperature lower than that of any of its components; used in dentistry mainly in solders. (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) |

| 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) |
