| reticulocyte | <haematology> Immature red blood cells normally restricted to the bone marrow and present in the blood stream in very low numbers (0.2-2%). An increase in numbers indicates increased proliferation in the bone marrow, for example following chemotherapy. (09 Oct 1997) |
| reticulocyte count | Determination of the number of reticulocytes in a measured volume of blood. Values for reticulocytes are expressed as a percentage of the erythrocyte count or in the form of a so-called "corrected" reticulocyte "index". An increase in circulating reticulocytes, often referred to as reticulocytosis, is among the simplest and most reliable signs of accelerated erythrocyte production. Reticulocytosis, or an increased reticulocyte count, occurs during active blood regeneration (stimulation of red bone marrow) and in certain anaemias, particularly congenital haemolytic anaemia. (12 Dec 1998) |
| reticulocyte lysate | Cell lysate produced from reticulocytes, used as an in vitro translation sytem. (18 Nov 1997) |
| reticulocytopenia | Paucity of reticulocytes in the blood. Synonym: reticulopenia. Origin: reticulocyte + G. Penia, poverty (05 Mar 2000) |
| reticulocytosis | An increase in the number of circulating reticulocytes above the normal, which is less than 1% of the total number of red blood cells; it occurs during active blood regeneration (stimulation of red bone marrow) and in certain anaemias, especially congenital haemolytic anaemia. Origin: reticulocyte + G. Osis, condition (05 Mar 2000) |
| reticuloendothelial | Denoting or referring to reticuloendothelium. (05 Mar 2000) |
| reticuloendothelial cell | A cell of the reticuloendothelial system. (05 Mar 2000) |
| reticuloendothelial system | The phagocytic system of the body, including the fixed macrophages of tissues, liver and spleen. Rather old fashioned term that is coming back into use, mononuclear phagocyte system is probably better when only phagocytes are meant. (18 Nov 1997) |
| reticuloendothelioma | An obsolete term for a localised reticulosis, or neoplasm derived from reticuloendothelial tissue. Origin: reticuloendothelium + G. -oma, tumour (05 Mar 2000) |
| reticuloendotheliosis | Hyperplasia of reticuloendothelial tissue, in any organ or tissue. A related concept is reticulosis which is an increase in reticuloendothelial elements. (12 Dec 1998) |
| reticuloendotheliosis virus, avian | A species of reticuloendotheliosis viruses of the genus retroviruses type b, mammalian that causes a chronic neoplastic and a more acute immunosuppressive disease in fowl. (12 Dec 1998) |
| reticuloendotheliosis viruses | A subgenus of retroviruses type b, mammalian comprising a few isolates from birds, with no known corresponding endogenous relatives. (12 Dec 1998) |
