| 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| formol-Zenker fixative | Zenker's fixative in which glacial acetic acid has been replaced by formalin.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) |
| allantoic fluid | The fluid within the allantoic cavity. (05 Mar 2000) |
| amniotic fluid | <anatomy, obstetrics> The fluid that surrounds the developing foetus within the amniotic sac. This environment cushions the baby from injury and plays an important role in foetal development. (05 Feb 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| amniotic fluid syndrome | <syndrome> Pulmonary embolic phenomena thought to be due to infusion of amniotic fluid containing epithelial squames into maternal blood vessels; shock ensues and sudden death may occur. (05 Mar 2000) |
| ascitic fluid | The serous fluid which accumulates in the peritoneal cavity in ascites. (12 Dec 1998) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| body fluid compartments | The two phases between which water and other body fluids are distributed: extracellular and intracellular. (12 Dec 1998) |
| Brodie fluid | An aqueous salt solution used in manometers designed for testing gas evolution or uptake, as in cell respiration. (05 Mar 2000) |
