| basocytopenia | A decrease in the number of basophilic granulocytes normally present in the circulating blood (difficult to evaluate, owing to the small and variable number normally present). Synonym: basocytopenia, basopenia. (05 Mar 2000) |
|---|---|
| basocytosis | The presence of an abnormally large number of basophilic granulocytes in the blood. Synonym: basocytosis. (05 Mar 2000) |
| basoerythrocyte | A red blood cell that manifests changes of basophilic degeneration, such as basophilic stippling, punctate basophilia, or basophilic granules. (05 Mar 2000) |
| basoerythrocytosis | An increase of red blood cells with basophilic degenerative changes, frequently observed in diseases characterised by prolonged hypochromic anaemia. (05 Mar 2000) |
| basograph | An instrument that makes graphic records of abnormalities of gait. Origin: baso-+ G. Grapho, to write (05 Mar 2000) |
| basolateral | Basal and lateral; specifically used to refer to one of the two major cytological divisions of the amygdaloid complex. See: amygdaloid body. (05 Mar 2000) |
| basolateral plasma membrane | <cell biology> The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes). (18 Nov 1997) |
| basometachromophil | Basometachromophile Staining metachromatically with a basic dye. See: metachromasia. (05 Mar 2000) |
| basommatophora | <zoology> A group of Pulmonifera having the eyes at the base of the tentacles, including the common pond snails. Origin: NL, fr. Gr. Base + eye + to bear. Source: Websters Dictionary (01 Mar 1998) |
| basopenia | Synonym: basophilic leukopenia. Origin: baso-+ G. Penia, poverty (05 Mar 2000) |
| basophil | <haematology> Mammalian granulocyte with large heterochromatic basophilic granules that contain histamine bound to a protein and heparin like mucopolysaccharide matrix. They are not phagocytic. Very similar to mast cells though it is not clear whether they have common lineage. (18 Nov 1997) |
| basophil adenoma | <tumour> A tumour of the adenohypophysis in which the cell cytoplasm stains with basic dyes, often ACTH producing. (05 Mar 2000) |
| basophil cell of anterior lobe of hypophysis | beta cell of anterior lobe of hypophysis |
| basophil degranulation test | An in vitro test used in the diagnosis of allergies including drug hypersensitivity. The allergen is added to the patient's white blood cells and the subsequent histamine release is measured. (12 Dec 1998) |
| basophil granule | A granule that stains readily with a basic dye. (05 Mar 2000) |
