| ketone bodies | The substances beta-hydroxybutyric acid, acetoacetic acid, and acetone, which are produced by fatty acid and carbohydrate metabolism in the liver in approximately a 78:20:2 ratio. Acetoacetate is produced from acetyl-CoA. most is enzymatically converted to beta-ketobutyrate, but a small amount is spontaneously decarboxylated to acetone. The ketone bodies can be used as fuels by muscle and brain tissue. In starvation and uncontrolled diabetes mellitus, large quantities are produced, causing metabolic acidosis and elevated blood and urine levels of all three ketone bodies. (12 Dec 1998) |

| Koch's blue bodies | Schizonts of Theileria parva, the causative agent of East Coast fever; found principally within endothelial cells of the spleen and lymph nodes. (05 Mar 2000) |
| Zuckerkandl's bodies | Small masses of chromaffin cells found near the sympathetic ganglia along the abdominal aorta. They serve as chemoreceptors responsive to oxygen, carbon dioxide, and hydrogen ion concentration, and help to control respiration. (12 Dec 1998) |
| ferruginous bodies | In the lungs, foreign inorganic or organic fibres coated by complexes of haemosiderin and glycoproteins, and believed to be formed by macrophages that have phagocytised the fibres. See: asbestos bodies. (05 Mar 2000) |
| Kurloff's bodies | Palely basophilic, granular inclusions sometimes observed in the cytoplasm of the large mononuclear leukocytes (probably lymphocytes) of guinea pigs and certain other animals. (05 Mar 2000) |
| Lallemand's bodies | Old term for small gelatinoid concretions sometimes observed in seminal fluid, old term for Bence Jones cylinders. Synonym: Trousseau-Lallemand bodies. (05 Mar 2000) |
| Landolt's bodies | Bipolar nerve cells lying between the retinal rods and cones in amphibia, reptiles, and birds. (05 Mar 2000) |
| leishman-donovan bodies | Small spheres found in the spleen and liver of patients with visceral leishmaniasis. The spheres are an alternate, non flagellated form of the parasitic protozoan Leishmania donovani which occurs once the parasite has invaded the cells of the reticuloendothelial system in the patients organs. The spheres are named after Sir William Leishman and Charles Donovan. (09 Oct 1997) |
| fuchsin bodies | Small, discrete, variably sized, spherical, intracytoplasmic, acidophilic, hyaline body's that stain deeply with fuchsin; they occur frequently in plasma cells in chronic inflammation, where they are believed to consist of gamma-globulin. Synonym: fuchsin bodies. (05 Mar 2000) |
| lewy bodies | Intracytoplasmic, eosinophilic, round to elongated inclusions found in vacuoles of injured or fragmented neurons. The presence of lewy bodies is the histological marker of the degenerative changes in parkinson disease but they may be seen in other neurological conditions. They are typically found in the substantia nigra and locus coeruleus but they are also seen in the basal forebrain, hypothalamic nuclei, and neocortex. (12 Dec 1998) |
| Lindner's bodies | Initial body's resembling inclusion body's found in scrapings of epithelial cells infected with trachoma. (05 Mar 2000) |
| Luse bodies | Collagen fibres with abnormally long spacing (exceeding 1000 A |
