| Schaumann bodies | Concentrically laminated calcified body's found in granulomas, particularly in sarcoidosis. Synonym: conchoidal bodies. (05 Mar 2000) |
|---|---|
| Herring bodies | <pathology> Granules within axons in the posterior lobe of the pituitary gland. Contain neurosecretory hormones. (18 Nov 1997) |
| Prowazek bodies | Historic term for either of two types of inclusion body's associated with certain diseases: 1) trachoma body's; 2) tiny, ovoid, granular forms, frequently in pairs, observed in the cytoplasm and in Guarnieri body's in the cutaneous squamous cells of man and animals infected with variola (smallpox) or vaccinia virus; probably the same as Paschen body's. (05 Mar 2000) |
| Prowazek-Greeff bodies | Distinctive, complex, intracytoplasmic forms found in the conjunctival epithelial cells of persons in the acute phase of trachoma, less frequently in later stages, varying from 1) discrete acidophilic granules (approximately 250 nm in diameter), to 2) irregular clumps of such material embedded in a basophilic matrix, to 3) relatively large basophilic body's (approximately 700 to 1000 nm in diameter), to 4) large basophilic body's that include discrete, tiny, acidophilic granules. Synonym: Halberstaedter-Prowazek bodies, Prowazek-Greeff bodies. (05 Mar 2000) |
| psammoma bodies | Mineralised body's occurring in the meninges, choroid plexus, and in certain meningiomas; composed usually of a central capillary surrounded by concentric whorls of meningocytes in various stages of hyaline change and mineralization; can also occur in benign and malignant epithelial tumours (often papillary) or with chronic inflammation. Synonym: sand bodies. Synonym: corpora arenacea. Synonym: calcospherite. (05 Mar 2000) |
| sclerotic bodies | Vegetative rounded muriform cells of dematiaceous fungi, characteristic of the causal agents of chromoblastomycosis in tissue. Synonym: copper pennies. (05 Mar 2000) |
| psittacosis inclusion bodies | Intracytoplasmic chlamydial microcolonies observed in bronchial epithelial cells infected with Chlamydia psittaci. (05 Mar 2000) |
| Hirano bodies | Paracrystalline inclusions found in the brain of patients with neurodegenerative disorders. (18 Nov 1997) |
| Howell-Jolly bodies | Spherical or ovoid eccentrically located granules, approximately 1 um in diameter, occasionally observed in the stroma of circulating erythrocytes, especially in stained preparations (as compared with wet unstained films); probably represent nuclear remnants, inasmuch as they can be stained with dyes that are rather specific for chromatin; the significance of the body's is not exactly known; they occur most frequently after splenectomy or in megaloblastic or severe haemolytic anaemia. Synonym: Jolly bodies. (05 Mar 2000) |
| hyaline bodies | Homogeneous eosinophilic inclusions in the cytoplasm of epithelial cells; in renal tubules, hyaline body's represent droplets of protein reabsorbed from the lumen. See: Mallory bodies, drusen. Synonym: fuchsin bodies. (05 Mar 2000) |
| hyaline bodies of pituitary | Accumulations of a gelatinous neurosecretory substance in the axons of the hypothalamohypophyseal tract in the posterior lobe of the hypophysis. (05 Mar 2000) |
| Negri bodies | Eosinophilic, sharply outlined, pathognomonic inclusion body's (2 to 10 um in diameter) found in the cytoplasm of certain nerve cells containing the virus of rabies, especially in Ammon's horn of the hippocampus. Synonym: Negri corpuscles. (05 Mar 2000) |
| nissl bodies | Large granular basophilic bodies found in the cytoplasm of neurons, composed of rough endoplasmic reticulum and free polyribosomes. (12 Dec 1998) |
| nuclear inclusion bodies | See: inclusion bodies. (05 Mar 2000) |
| Deetjen's bodies | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
