| 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) |
| dense bodies | <cell biology> Areas of electron density associated with the thin filaments in smooth muscle cells. Some are associated with the plasma membrane, others are cytoplasmic. (12 Jan 1998) |
| Dohle bodies | Discrete round or oval body's ranging in diameter from just visible to 2 um, which stain sky blue to gray blue with Romanowsky stains, found in neutrophils of patients with infections, burns, trauma, pregnancy, or cancer. Synonym: Dohle inclusions, leukocyte inclusions. (05 Mar 2000) |
| Donovan's bodies | Clusters of blue or black staining, bipolar chromatin condensations in large mononuclear cells in granulation tissue infected with Calymmatobacterium granulomatis. (05 Mar 2000) |
| inclusion bodies | <cell biology> Nuclear or cytoplasmic structures with characteristic staining properties, usually found at the site of virus multiplication. Semi crystalline arrays of virions, capsids or other viral components. (13 Nov 1997) |
| inclusion bodies, viral | An area showing altered staining behaviour in the nucleus or cytoplasm of a virus-infected cell. Some inclusion bodies represent "virus factories" in which viral nucleic acid or protein is being synthesised; others are merely artifacts of fixation and staining. One example, negri bodies, are found in the cytoplasm or processes of nerve cells in animals that have died from rabies. (12 Dec 1998) |
| quadrigeminal bodies | See: inferior colliculus, superior colliculus. Synonym: corpora quadrigemina. (05 Mar 2000) |
| interrenal bodies | Distinct paired or unpaired structures in all fishes, which lie in close proximity to the kidney, homologous to the cortical tissue of the mammalian adrenal gland. Synonym: interrenal glands. (05 Mar 2000) |
