| mononuclear | Having only one nucleus; used especially in reference to blood cells. (05 Mar 2000) |
|---|---|
| mononuclear phagocyte | <haematology> Monocytes and their differentiated products, macrophages. Mononuclear cells are leucocytes other than polymorphonuclear cells and include lymphocytes. (18 Nov 1997) |
| mononuclear phagocyte system | A widely distributed collection of both free and fixed macrophages derived from bone marrow precursor cells by way of monocytes; their substantial phagocytic activity is mediated by immunoglobulin and the serum complement system. In both connective and lymphoid tissue, they may occur as free and fixed macrophages; in the sinusoids of the liver, as Kupffer cells; in the lung, as alveolar macrophages; and in the nervous system, as microglia. Synonym: system of macrophages. (05 Mar 2000) |
| leukocytes, mononuclear | Mature lymphocytes and monocytes transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules. (12 Dec 1998) |
| absolute leukocytosis | An actual increase in the total number of leukocytes in the circulating blood, as distinguished from a relative increase (such as that observed in dehydration). (05 Mar 2000) |
| agonal leukocytosis | One that occurs in a person just prior to death, especially in one who has a "slow death." Synonym: agonal leukocytosis. (05 Mar 2000) |
| basophilic leukocytosis | The presence of an abnormally large number of basophilic granulocytes in the blood. Synonym: basocytosis. (05 Mar 2000) |
| relative leukocytosis | An increased proportion of one or more types of leukocytes in the circulating blood, without an actual increase in the total number of white blood cells. (05 Mar 2000) |
| physiologic leukocytosis | Any form of leukocytosis that is associated with apparently normal situations and that is not directly related to a pathologic condition; e.g., the temporary increase in the total number of white blood cells that may occur during a single day, or from day to day, as well as in the newborn period, during childhood, after strenuous exercise, during attacks of paroxysmal tachycardia, and in association with various other situations. (05 Mar 2000) |
| monocytic leukocytosis | An abnormal increase in the number of monocytes in the circulating blood. Synonym: monocytic leukocytosis. (05 Mar 2000) |
| neutrophilic leukocytosis | Too many neutrophils. (12 Dec 1998) |
| digestive leukocytosis | Leukocytosis occurring normally after ingestion of food. (05 Mar 2000) |
| distribution leukocytosis | An abnormally large proportion of one or more types of leukocytes. (05 Mar 2000) |
| terminal leukocytosis | One that occurs in a person just prior to death, especially in one who has a "slow death." Synonym: agonal leukocytosis. (05 Mar 2000) |
| emotional leukocytosis | An abnormally high white blood cell count that is thought to be related only to an emotional disturbance. (05 Mar 2000) |
