Definition of leucocyte in English: leucocyte(also leukocyte) noun ˈluːkə(ʊ)sʌɪt Physiology A colourless cell which circulates in the blood and body fluids and is involved in counteracting foreign substances and disease; a white (blood) cell. There are several types, all amoeboid cells with a nucleus, including lymphocytes, granulocytes, and monocytes. Example sentencesExamples - Lymphocytes and granular leucocytes are also found in the stroma.
- White blood cells (also called leukocytes or WBCs) help the body fight infections.
- Some giant cells exhibited phagocytosis of mononuclear tumor cells and leukocytes such as lymphocytes and polymorphonuclear cells.
- Reduction of leucocytes in red blood cell concentrates by filtration results in less alloimmunisation in patients receiving transfusions and transplants
- Immune cells or leukocytes circulate continuously from the blood, into various organs, and back into the blood.
- Finally, there were other techniques for separating red blood cells from leucocytes.
- White blood cells or leucocytes are complete cells because they contain a nucleus and other vital organelles.
- Many of these are inflammatory cells, such as leukocytes and macrophages.
- Mononuclear leukocytes consist of monocytes and lymphocytes.
- At baseline, levels of circulating leucocytes and vascular cell adhesion molecules were elevated in the sickle cell mice.
- Necrotic tissue, blood vessels, and leukocytes were excluded from the quantification process.
- For all these cases, hepatocytes were more immunoreactive than endothelial cells and leukocytes.
- The epithelium covering the tonsils is extensively infiltrated by lymphocytes, plasma cells, and polymorphonuclear leucocytes.
- The myeloid lineage gives rise to the rest of the white blood cells or leukocytes, which all derive from the bone marrow in adults.
- It also stimulates the production and activity of polymorphonuclear leukocytes and promotes adhesion of immune cells to the endothelium.
- In some areas, polymorphonuclear leukocytes and eosinophils were intermingled with the small lymphocytes.
- Ehrlich had made a clear distinction between acidophil and basophil leukocytes.
- This shows an infiltration of polymorphonuclear leukocytes with foci of necrosis, thrombosis, and hemorrhage.
- The injured or ruptured cells attract neutrophil leukocytes and activate alveolar macrophages, causing inflammation in the lung.
- This was due to increases in both polymorphonuclear leukocytes and macrophages.
Derivatives adjectiveluːkə(ʊ)ˈsɪtɪk Physiology The ovalbumin-treated mice, but not the control mice, displayed widespread deposition of collagen beneath the airway epithelial cell layer and in the interstitium at sites of leukocytic infiltration. Example sentencesExamples - When the history is equivocal, nasal cytology to detect the presence of eosinophils associated with allergic rhinitis or to detect the leukocytic infiltrates associated with acute bacterial or viral infections is indicated.
- Thus, changes in airway hyperresponsiveness between experimental groups did not result from differences in leukocytic infiltration into the lung in response to Aspergillus extract.
- Inhibited proteases of leukocytic origin probably are partly responsible for the damage to the lung in the absence of the major protease inhibitor.
