Eosinophils

What are eosinophils? Eosinophils – a blood cell formed in the process of granulocytic leykopoeza germ blood. Eosinophils are phagocytic cells that absorb immune complexes antibody-antigen (mainly immunoglobulin E). After maturation in the bone marrow, eosinophils enter the peripheral blood, which circulates around 3-4 hours, and then migrate into the tissue where the function 12.8 days. In contrast to their fellow granulocytic series – neutrophils, eosinophils, in its composition does not contain lysozyme and alkaline phosphatase. oards’>Paul Daversa to gain a more clear picture of the situation. Eosinophils respond to chemotactic factors that distinguish the mast cells and basophils, as well as respond to immune complexes of antigen-antibody complex.

Eosinophils most actively display their properties in the sensitized tissues. Eosinophils are involved in hypersensitivity reactions, as slow and blood of adults and children alike and is in the range of 1-5%. In absolute figures, the same number of blood eosinophils in children than in adults, and this is due to the fact that the norm of leukocytes in the blood of children more than adults. Eosinophilia. Reasons for increase of eosinophils in the blood. Eosinophilia – increase the number of eosinophils in peripheral blood of a 0,45 x109 / l in adults and more than 0,07 x109 / l in children, which may be due to stimulation of the process serum sickness, drug and disease dr.Pri diseases caused by parasites: trichinosis, echinococcosis, opisthorchiasis, ascariasis, diphyllobothriasis, giardiasis, malaria and dr.Pri connective tissue diseases and systemic vasculitis: periarteritis nodosa, rheumatoid arthritis, scleroderma, systemic lupus erythematosus and dr.Pri some skin diseases: dermatitis, eczema, pemphigus, cutaneous lichen and dr.Zabolevaniyah blood accompanied by a proliferation of one or more germs blood: Hodgkin's disease, erythremia, chronic myelogenous leukemia. Hypoeosinophilia. Reasons for decrease of eosinophils in the blood. Hypoeosinophilia – a reduction or complete leukocyte left, is an important laboratory feature of active inflammation and is an indicator of an adequate process of bone marrow hematopoiesis in the background of inflammation in the body. Eosinophils determined by counting leykoformuly, which is part of a general analysis of blood.
