| giant cell tumour of bone | A bone tumour composed of cellular spindle-cell stroma containing scattered multinucleated giant cells resembling osteoclasts. The tumours range from benign to frankly malignant lesions. The tumour occurs most frequently in an end of a long tubular bone in young adults. (12 Dec 1998) |
|---|---|
| giant cell tumour of tendon sheath | A nodule, possibly inflammatory in nature, arising commonly from the flexor sheath of the fingers and thumb; composed of fibrous tissue, lipid-and haemosiderin-containing macrophages, and multinucleated giant cells. Synonym: localised nodular tenosynovitis. (05 Mar 2000) |
| giant cell tumours | Tumours of bone tissue or synovial or other soft tissue characterised by the presence of giant cells. The most common are giant cell tumour of tendon sheath and giant cell tumour of bone. (12 Dec 1998) |
| red blood cell | <haematology> Cell specialised for oxygen transport, having a high concentration of haemoglobin in the cytoplasm (and little else). Biconcave, anucleate discs, 7nm diameter in mammals, nucleus contracted and chromatin condensed in other vertebrates. Acronym: RBC (18 Nov 1997) |
| red blood cell cast | A urinary cast composed of a matrix containing red cells in various stages of degeneration and visibility, characteristic of glomerular disease or renal parenchymal bleeding. Synonym: red cell cast. (05 Mar 2000) |
| red blood cell count | A normal value is 4.6-6.2 million RBC's per cubic millimetre of blood. This number can increase in cases of dehydration (fluid loss) or severe lung disease. Interestingly, red blood cell counts are much higher in those who live at high altitude, because of the increased demand for oxygen carrying capacity. (27 Sep 1997) |
| red blood cell indices | Laboratory measurements of red blood cell volume, size and haemoglobin concentration. These values are used to point to the specific cause for anaemia (iron deficiency, B12 deficiency, etc.) (27 Sep 1997) |
| red cell adherence phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| red cell adherence test | The diagnostic application of the immune adhesion phenomenon. Synonym: erythrocyte adherence test, immune adhesion test, red cell adherence test. (05 Mar 2000) |
| red-cell aplasia, pure | Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. (12 Dec 1998) |
| red cell cast | A urinary cast composed of a matrix containing red cells in various stages of degeneration and visibility, characteristic of glomerular disease or renal parenchymal bleeding. Synonym: red cell cast. (05 Mar 2000) |
| Reed-Sternberg cell | <haematology, pathology> A type of cell that appears in patients with Hodgkin's disease. The number of these cells increases as the disease advances. (12 May 1997) |
| viable cell count | Number of cells in a given area or volume that are thriving. (05 Mar 2000) |
| mature cell leukaemia | Chronic granulocytic leukaemia. (05 Mar 2000) |
| Mauthner's cell | <marine biology> A large neuron of the spinal cord with its cell body located in the metencephalon of fish and amphibia. (05 Mar 2000) |
