| lymphoma, small cleaved-cell, diffuse | An intermediate-grade malignant lymphoma in which the neoplastic cells (B-lymphocytes) exhibit variability in size, configuration, and degree of differentiation. The cells have distinctive nuclei, irregular in shape, with marked indentations and angularity. (12 Dec 1998) |
|---|---|
| lymphoma, small cleaved-cell, follicular | A low-grade malignant lymphoma of predominantly follicular pattern. Follicles are of relatively uniform size and shape and the cells are usually somewhat larger than normal lymphocytes. Nuclei are irregular with prominent indentations and cytoplasm can rarely be identified. Cells exhibiting these characteristics are often called centrocytes. (12 Dec 1998) |
| lymphoma, small lymphocytic | A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukaemia (cll; leukaemia, lymphocytic, chronic). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics. (12 Dec 1998) |
| lymphoma, small noncleaved-cell | A high-grade malignant lymphoma that includes both burkitt tumour (burkitt lymphoma) and other lymphomas previously designated undifferentiated non-burkitt type. Nuclei in burkitt tumour are round to ovoid and uniform in size. The non-burkitt type exhibits greater nuclear variation and less evidence of cellular maturation with a correspondingly lesser degree of differentiation. (12 Dec 1998) |
| 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) |
| african green monkey kidney cell | <cell culture> Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain viruses like poliovirus. (05 Feb 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) |
| anterior surface of kidney | The anterior surface of the kidney. Synonym: facies anterior renis. (05 Mar 2000) |
| anti-kidney serum nephritis | Experimental glomerulonephritis produced by injection of antiserum to kidney. (05 Mar 2000) |
| arciform veins of kidney | Veins that parallel the arcuate arteries, receive blood from interlobular veins and straight venules, and terminate in interlobar veins. Synonym: venae arcuatae renis, arciform veins of kidney. (05 Mar 2000) |
| arcuate arteries of kidney | Curved arteries at the corticomedullary border, arising from interlobar arteries and giving rise to interlobular arteries. Synonym: arteriae arcuatae renis. (05 Mar 2000) |
| arcuate veins of kidney | Veins that parallel the arcuate arteries, receive blood from interlobular veins and straight venules, and terminate in interlobar veins. Synonym: venae arcuatae renis, arciform veins of kidney. (05 Mar 2000) |
