| mast cell | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |

| mast cell leukaemia | A form of granulocytic leukaemia in which there are unusually great numbers of basophilic granulocytes in the tissues and circulating blood; in some instances, the immature and mature basophilic forms may represent from 40 to 80% of the total numbers of white blood cells. Synonym: mast cell leukaemia. (05 Mar 2000) |
| ghost cell | <haematology> A red blood cell which has had all of its cytoplasmic contents removed by cell lysis so that only its outer cytoplasmic membrane remains. (17 Dec 1997) |
| ghost cell glaucoma | Glaucoma occurring after vitrectomy, arising from erythrocyte membranes blocking outflow channels of aqueous humor. (05 Mar 2000) |
| 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) |
