| Zenker, Friedrich | <person> German pathologist, 1825-1898. See: Zenker's degeneration, Zenker's diverticulum, Zenker's fixative, Zenker's necrosis, Zenker's paralysis, formol-Zenker fixative. (05 Mar 2000) |
|---|---|
| Zenker's degeneration | A form of severe hyaline degeneration or necrosis in skeletal muscle, occurring in severe infections. Synonym: waxy degeneration, Zenker's necrosis. (05 Mar 2000) |
| Zenker's diverticulum | <pathology> Herniation of the mucosa of the oesophagus through a defect in the wall of the oesophagus. The location is usually in the upper one-third of the oesophagus. (12 Nov 1997) |
| Zenker's fixative | A rapid fixative consisting of mercuric chloride, potassium dichromate, sodium sulfate, glacial acetic acid, and water, useful for trichrome stains; must be washed to remove potassium dichromate and treated with iodine solution to remove mercuric chloride; tissues tend to become brittle if left in the fixative for more than 24 hours. (05 Mar 2000) |
| Zenker's necrosis | A form of severe hyaline degeneration or necrosis in skeletal muscle, occurring in severe infections. Synonym: waxy degeneration, Zenker's necrosis. (05 Mar 2000) |
| Zenker's paralysis | Paresthesia and paralysis in the area of the external popliteal nerve. (05 Mar 2000) |
| formol-Zenker fixative | Zenker's fixative in which glacial acetic acid has been replaced by formalin. (05 Mar 2000) |
| acetic solution | A vinegar. (05 Mar 2000) |
| amaranth solution | A 1% solution of amaranth (trisodium naphthol sulfonic acid), a synthetic vivid red dye, stable in acid and intensified in sodium hydroxide solution; used as a red or pink colourant in liquid pharmaceuticals. (05 Mar 2000) |
| aqueous solution | <chemistry> A solution in which water is the dissolving medium or solvent. (09 Jan 1998) |
| barium solution | A liquid containing barium sulfate, which shows up on X-rays. It outlines organs of the body so they can be seen on X-ray film. (12 Dec 1998) |
| Benedict's solution | <chemistry> An aqueous solution of sodium citrate, sodium carbonate, and copper sulfate which changes from its normal blue colour to orange, red, or yellow in the presence of a reducing sugar such as glucose. See: Benedict's test for glucose. (14 Aug 2000) |
| Burow's solution | A preparation of aluminium subacetate and glacial acetic acid, used for its antiseptic and astringent action on the skin. (05 Mar 2000) |
| Gallego's differentiating solution | A dilute solution of formaldehyde and acetic acid used in a modified Gram stain to differentiate and enhance the basic fuchsin binding to Gram-negative microorganisms. (05 Mar 2000) |
| Gey's solution | A salt solution usually used in combination with naturally occurring body substances (e.g., blood serum, tissue extracts) and/or more complex chemically defined nutritive solution's for culturing animal cells. (05 Mar 2000) |
