Along with Döhle bodies and toxic vacuolation, which are two other findings in the cytoplasm of granulocytes, toxic granulation is a peripheral blood film finding suggestive of an inflammatory process. [1] Toxic granulation is often found in patients with bacterial infection and sepsis, [1] [2] although the finding is nonspecific. [3]
Toxic vacuolation is associated with sepsis, particularly when accompanied by toxic granulation. [4] The finding is also associated with bacterial infection, [3] alcohol toxicity, liver failure, [4] and treatment with granulocyte colony-stimulating factor, a cytokine drug used to increase the absolute neutrophil count in patients with neutropenia.
Granulocytopenia is an abnormally low concentration of granulocytes in the blood. This condition reduces the body's resistance to many infections. Closely related terms include agranulocytosis (etymologically, "no granulocytes at all"; clinically, granulocyte levels less than 5% of normal) and neutropenia (deficiency of neutrophil granulocytes).
In 1989, contaminated L-tryptophan supplements caused a deadly form of eosinophilia known as eosinophilia-myalgia syndrome, which was reminiscent of the toxic oil syndrome in Spain in 1981. Reference ranges for blood tests of white blood cells, comparing eosinophil granulocyte amount (shown in light red) with other cells
Döhle bodies are light blue-gray, oval, basophilic, leukocyte inclusions located in the peripheral cytoplasm of neutrophils.They measure 1–3 μm in diameter. Not much is known about their formation, but they are thought to be remnants of the rough endoplasmic reticulum.
Neutrophils are the primary white blood cells that respond to a bacterial infection, so the most common cause of neutrophilia is a bacterial infection, especially pyogenic infections.
Vice President JD Vance vowed Monday that the Trump administration will “finish the cleanup” of East Palestine, Ohio, during a visit to mark the 2-year anniversary of a toxic train derailment. ...
Degranulation in mast cells is part of an inflammatory response, and substances such as histamine are released. Granules from mast cells mediate processes such as "vasodilation, vascular homeostasis, innate and adaptive immune responses, angiogenesis, and venom detoxification."
