| elementary bodies | Old term for virions, especially the largest virus particles, visible by light microscopy when stained. Synonym: platelet. (05 Mar 2000) |

| elementary granule | A particle of blood dust, or haemoconia. (05 Mar 2000) |

| elementary particle interactions | The interactions of particles responsible for their scattering and transformations (decays and reactions). Because of interactions, an isolated particle may decay into other particles. Two particles passing near each other may transform, perhaps into the same particles but with changed momenta (elastic scattering) or into other particles (inelastic scattering). Interactions fall into three groups: strong, electromagnetic, and weak. (12 Dec 1998) |
| elementary particles | <radiobiology> at a nuclear-energy level: electron & positron - seem to be stable, proton - thought to be stable, life greater than 10^30 sec, neutron - decays in ?6 min unless its in a nucleus, which often extends its life. Other particles important for nuclear energy: Muon, neutrino (m, e, tau), photon, Muonic atoms, Pi-meson antiparticles (09 Oct 1997) |
| elementary step | <chemistry> Reaction mechanisms are broken down into elementary steps. For each step the the reactants are directly involved in forming the transition state. Therefore a rate law can be written from an elementary step but not from an overall reaction. (09 Jan 1998) |
| Zimmermann's elementary particle | <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) |
| alcoholic hyaline bodies | Large, poorly defined accumulations of eosinophilic material in the cytoplasm of damaged hepatic cells in certain forms of cirrhosis and marked fatty change especially due to alcoholism. Synonym: alcoholic hyalin, alcoholic hyaline bodies. (05 Mar 2000) |
| Alder bodies | Granular inclusions in polymorphonuclear leukocytes; they take on a dark colour with Giemsa-Wright stain and react metachromatically with toluidine blue. See: Alder's anomaly. (05 Mar 2000) |
| amyloid bodies of the prostate | An obsolete term for small masses of colloid material often present in the tubules of the gland. See: corpus amylaceum. (05 Mar 2000) |
| aortic bodies | Small clusters of chemoreceptive and supporting cells located near the aortic arch, the pulmonary arteries, and the coronary arteries. The aortic bodies sense pH, carbon dioxide, and oxygen concentrations in the blood and participate in the control of respiration. (12 Dec 1998) |
| Arnold's bodies | Small portions or minute fragments of erythrocytes (sometimes mistaken for blood platelets), or small "ghosts" of erythrocytes. (05 Mar 2000) |
| asbestos bodies | Ferruginous body's with asbestos fibres as a core; a histologic hallmark of exposure to asbestos. (05 Mar 2000) |
| Aschoff bodies | <pathology> Small granulomas composed of macrophages, lymphocytes and multinucleate cells grouped around eosinophilic hyaline material derived from collagen. Characteristic of the myocarditis of rheumatic fever. (18 Nov 1997) |
| Auer bodies | Rod-shaped structures of uncertain nature in the cytoplasm of immature myeloid cells, especially myeloblasts, in acute myelocytic leukaemia; may be an abnormal form of lysosomes; they contain peroxidase and acid phosphatase, and stain red by azure-eosin stains. Synonym: Auer rods. (05 Mar 2000) |
| Babes-Ernst bodies | Intracellular granules, present in many species of bacteria, which possess a strong affinity for nuclear stains. (05 Mar 2000) |
| bigeminal bodies | A bilateral single swelling of the roofplate of the embryonic midbrain that later in development becomes subdivided into a superior and an inferior colliculus. See: quadrigeminal bodies. Synonym: corpora bigemina. (05 Mar 2000) |
