| macrocyte | <haematology> Abnormally large red blood cell, numerous in pernicious anaemia. (27 Jan 1998) |
|---|---|
| macrocythemia | The occurrence of unusually large numbers of macrocytes in the circulating blood. Synonym: macrocytosis, megalocythemia, megalocytosis. Origin: macrocyte + G. Haima, blood Hyperchromatic macrocythemia, an inexact term frequently used for macrocytes that contain an unusually large amount of haemoglobin, but are actually normochromic; although the total mass of haemoglobin is greater than normal (owing to the large cells), the percentage of haemoglobin in the cells is not greater than normal. (05 Mar 2000) |
| macrocytic | Enlarged red blood cells (RBCs). Folic acid deficiency is one cause of macrocytic anaemia. (12 Dec 1998) |
| macrocytic achylic anaemia | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
| macrocytic anaemia | Any anaemia in which the average size of circulating erythrocytes is greater than normal, i.e., the mean corpuscular volume is 94 cu um or more (normal range, 82 to 92 cu um), including such syndromes as pernicious anaemia, sprue, coeliac disease, macrocytic anaemia of pregnancy, anaemia of diphyllobothriasis, and others. Synonym: megalocytic anaemia. (05 Mar 2000) |
| macrocytic anaemia of pregnancy | An anaemia occurring in pregnancy, related to folate deficiency and characterised by a low level of haemoglobin and a reduced number of erythrocytes, which are larger than normal (macrocytes). (05 Mar 2000) |
| macrocytic anaemia tropical | The macrocytic, megaloblastic anaemia of tropical sprue. (05 Mar 2000) |
| macrocytic hyperchromia | Hyperchromatic macrocythemia; a misnomer inasmuch as the red blood cells are larger than normal, the total amount of haemoglobin per cell is increased, but the percentage of haemoglobin per cell is usually in the normochromic range. (05 Mar 2000) |
| macrocytosis | <haematology> Macrocytosis is enlargement of the red blood cells as defined by a red cell mean corpuscular volume (MCV) of greater than 100 fl. Macrocytosis is present in 1 to 4 % of the adult population. The most common cause is alcoholism. Other causes include: nutritional deficiencies (B12 and folate), chemotherapy, drug side effects, haemolysis, liver dysfunction, myelodysplasia and hypothyroidism. (27 Jan 1998) |
| macrodactyl | <ornithology> One of a group of wading birds (Macrodactyli) having very long toes. Alternative forms: macrodactyle. Origin: Gr. Long-fingered; long + finger: cf. F. Macrodactyle. Source: Websters Dictionary (01 Mar 1998) |
| macrodactylia | Condition characterised by enlargement of one or more digits (fingers or toes). Synonym: dactylomegaly, macrodactylia, macrodactylism, macrodactyly, megalodactylia, megalodactylism, megalodactyly. Origin: mega-+ G. Daktylos, digit (05 Mar 2000) |
| macrodactylous | <zoology> Having long toes. Source: Websters Dictionary (01 Mar 1998) |
| macrodiagonal | <chemistry> The longer of two diagonals, as of a rhombic prism. See Crystallization. Origin: Macro- + diagonal. Source: Websters Dictionary (01 Mar 1998) |
| macrodome | <chemistry> A dome parallel to the longer lateral axis of an orthorhombic crystal. See Dome. Origin: Macro- + dome. Source: Websters Dictionary (01 Mar 1998) |
| macrodont | <zoology> Having large teeth. A macrodont animal. Origin: Macro- + Gr, a tooth. Source: Websters Dictionary (01 Mar 1998) |
