| myelodysplasia | Abnormal or defective formation of the bone marrow cells. Origin: Gr. Plassein = to form (27 Sep 1997) |
|---|---|
| myelodysplastic syndrome | <syndrome> A group of disorders characterised by low white blood cell counts, low platelet counts, and, in some cases, increased monocytes. The primary problem is in the bone marrow cellularity. (27 Sep 1997) |
| myelodysplastic syndromes | Conditions in which the bone marrow shows qualitative and quantitative changes suggestive of a preleukaemic process, but having a chronic course that does not necessarily terminate as acute leukaemia. (12 Dec 1998) |
| myelofibrosis | A progressive disease of the bone marrow where neoplastic bone marrow stem cells lodge and grow in multiple sites outside the bone marrow. Typically, there is enlargement of the spleen and a gradual replacement of the bone marrow elements by fibrosis (scarring), progressive anaemia and variable changes in the number of white blood cells and platelets. Diagnosis is by bone marrow biopsy. There is no definitive treatment for this disorder that has been shown to affect life span favorably. (27 Sep 1997) |
| myelogenesis | 1. Development of bone marrow. 2. Development of the central nervous system. 3. Formation of myelin around an axon. (05 Mar 2000) |
| myelogenetic | Myelogenic 1. Relating to myelogenesis. 2. Produced by or originating in the bone marrow. Synonym: myelogenous. (05 Mar 2000) |
| myelogenic | <physiology> Derived from, or pertaining to, the bone marrow. Origin: Gr. Marrow + the root of to be born. Source: Websters Dictionary (01 Mar 1998) |
| myelogenic sarcoma | <tumour> Sarcoma originating in the bone marrow. (05 Mar 2000) |
| myelogenous | Referring to myelocytes, a type of white blood cell. Also called myeloid. (12 Dec 1998) |
| myelogone | Myelogonium An immature white blood cell of the myeloid series that is characterised by a relatively large, fairly deeply stained, finely reticulated nucleus that contains palely stained nucleoli, and a scant amount of rimlike, nongranular, moderately basophilic cytoplasm. Myelogones are difficult to distinguish from lymphoblasts and monoblasts, unless one evaluates them in relation to the more mature forms usually associated with the younger cells. Origin: myelo-+ G. Gone, seed (05 Mar 2000) |
| myelogram | <investigation> A diagnostic procedure where a radiopaque contrast dye is injected into the spinal canal. X-rays are then performed which reveal the anatomy of the spinal canal. Myelograms can be used to diagnosis disk disease, spinal stenosis and tumours of the spinal canal. MRI and CT scanning have largely displaced the use of this more invasive test. (27 Sep 1997) |
| myelography | <radiology> Contrast material, iohexol: 15 cc of 180, 10 ml of 240, pattern: intramedullary, cord widened (on 2 views!!), intradural - extramedullary, meniscus sign, extradural, featureless sac (12 Dec 1998) |
| myeloic | Pertaining to the tissue and precursor cells from which neutrophils, eosinophils, and basophils are derived. (05 Mar 2000) |
| myeloid | Collective term for the nonlymphocyte groups of white blood cells. It includes cells from the granulocyte, monocyte and platelet lineages. (13 Nov 1997) |
| myeloid cell | <haematology, pathology> One of the two classes of marrow derived blood cells, includes megakaryocytes, erythrocyte precursors, mononuclear phagocytes and all the polymorphonuclear granulocytes. That all these are ultimately derived from one stem cell lineage is shown by the occurrence of the Philadelphia chromosome in these, but not lymphoid, cells. most authors tend, however, to restrict the term myeloid to mononuclear phagocytes and granulocytes and commonly distinguish a separate erythroid lineage.

| myeloablation |
A severe form of myelosuppression. Myelosuppression is a condition in which bone marrow activity is decreased, resulting in fewer red blood cells, white blood cells, and platelets. It is a side effect of some cancer treatments.
