|---|---|
| cerebrocortical necrosis | A noninfectious disease of ruminants characterised by a tissue-thiamine deficiency and by amaurosis and strabismus, followed by recumbency, opisthotonos, and convulsions. Synonym: cerebrocortical necrosis. (05 Mar 2000) |
| retinal necrosis syndrome, acute | <ophthalmology> Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome. (12 Dec 1998) |
| coagulation necrosis | A type of necrosis in which the affected cells or tissue are converted into a dry, dull, fairly homogeneous eosinophilic mass without nuclear staining, as a result of the coagulation of protein as occurs in an infarct; microscopically, the necrotic process involves chiefly the cells, and remnants of histologic elements (e.g., elastin, collagen, muscle fibres) may be recognizable, as well as "ghosts" of cells and portions of cell membranes; may be caused by heat, ischemia, and other agents that destroy tissue, including enzymes that would continue to alter the devitalised cellular substance. (05 Mar 2000) |
| colliquative necrosis | An obsolete term for liquefactive necrosis. (05 Mar 2000) |
| mummification necrosis | A form of gangrene in which the involved part is dry and shriveled. Synonym: cold gangrene, mummification necrosis, mummification. (05 Mar 2000) |
| contraction band necrosis | A microscopic change in myocardial cells in which excessive contraction, associated with elevated intracellular calcium and serum norepinephrine, causes the formation of transverse amorphous band's in the fibres which are then incapable of contracting again. Synonym: contraction band necrosis. (05 Mar 2000) |
| myocardial necrosis | Irreversible destruction of myocardial (heart muscle) cells. (27 Sep 1997) |
| postpartum pituitary necrosis syndrome | <syndrome> Hypopituitarism arising from a severe circulatory collapse postpartum, with resultant pituitary necrosis. Synonym: postpartum pituitary necrosis syndrome, thyrohypophysial syndrome. (05 Mar 2000) |
| cystic medial necrosis | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| progressive emphysematous necrosis | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| hepatic necrosis | A severe and rapidly progressive form of hepatitis accompanied by hepatocellular death and the signs and symptoms of hepatic failure. May be a complication of hepatitis B, C or D. (27 Sep 1997) |
| simple necrosis | A stage of coagulation necrosis; the occurrence of a coarsely granular or hyaline change in the cytoplasm, and the lack of a recognizable nucleus, with the general configuration of the dead cells being relatively unchanged. (05 Mar 2000) |
| necrosis | <pathology> The sum of the morphological changes indicative of cell death and caused by the progressive degradative action of enzymes, it may affect groups of cells or part of a structure or an organ. Origin: Gr. Nekrosis = deadness (18 Nov 1997) |
| necrosis bacillus | A species of gram-negative, non-spore-forming bacteria isolated from the natural cavities of man and other animals and from necrotic lesions, abscesses, and blood. (12 Dec 1998) |
