| tissue culture | <cell culture> Originally the maintenance and growth of pieces of explanted tissue (plant or animal) in culture away from the source organism. Now usually refers to the (much more frequently used) technique of cell culture, using cells dispersed from tissues or distant descendants of such cells. (18 Nov 1997) |
|---|---|
| tissue culture infectious dose | The quantity of a cytopathogenic agent, such as a virus, that will produce a cytopathic effect in 50% of the cultures inoculated. (05 Mar 2000) |
| tissue culture plastic | <cell culture> Polystyrene that has been rendered wettable by oxidation, a treatment that increases its adhesiveness for cells from animal tissues and without which anchorage dependent cells will not grow. Commercially achieved by treatment known as glow discharge. (18 Nov 1997) |
| elective culture | A method of isolating microorganisms capable of utilizing a specific substrate by incubating an inoculum in a medium containing the substrate; the medium usually contains substances or has characteristics that inhibit the growth of unwanted microorganisms. Synonym: enrichment culture. (05 Mar 2000) |
| enrichment culture | <cell culture, microbiology> Use of selective culture media and incubation conditions to isolate microorganisms directly from nature. (09 Oct 1997) |
| type culture | A type strain of microorganism preserved in a culture collection as the standard. (05 Mar 2000) |
| faecal culture | <investigation, microbiology> A test used to identify pathogenic organisms in the stools that may be responsible for gastroenteritis. Often performed in cases of unexplained diarrhoea. May indicate bacterial, viral or parasitic disease. Cultures are also helpful in assisting the selection an appropriate antibiotic agent. See: traveler's diarrhoea. (27 Sep 1997) |
| Loeffler's blood culture medium | A culture medium consisting of beef blood serum, sheep blood serum, and beef bouillon containing peptone, glucose, and sodium chloride; used for the isolation of Corynebacterium diphtheriae. (05 Mar 2000) |
| Lowenstein-Jensen culture medium | Primary mycobacterial recovery media composed of fresh whole eggs, defined salts, glycerol, potato flour, and malachite green (as an inhibitory agent). Synonym: Lowenstein-Jensen medium. (05 Mar 2000) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
| acute kidney failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| acute kidney transplant rejection | <radiology> Findings on ultrasound: globular enlargment of the kidney, swelling and hypoechogenicity of the medullary pyramids, indistinct cortico-medullary junction, foci in the renal cortex (12 Dec 1998) |
| amyloid kidney | A kidney in which amyloidosis has occurred, usually in association with some chronic illness such as multiple myeloma, tuberculosis, osteomyelitis, or other chronic suppurative inflammation; such kidney's are moderately enlarged and grossly manifest a waxy appearance, with amyloid deposited beneath the endothelium in the glomerular loops and in the arterioles, apparently beginning as foci of thickening of the basement membranes. Synonym: waxy kidney. (05 Mar 2000) |
| anterior inferior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris inferioris renis, artery of anterior {inferior segment of kidney}. (05 Mar 2000) |
| anterior superior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris superioris renis, artery of anterior {superior segment of kidney}. (05 Mar 2000) |
