| mitochondrial swelling | Increase in volume of mitochondria due to an influx of fluid; it occurs in hypotonic solutions due to osmotic pressure and in isotonic solutions as a result of altered permeability of the membranes of respiring mitochondria. (12 Dec 1998) |
| disease, mitochondrial | Mutations (changes) in the mitochondrial chromosome are responsible for a number of disorders including an eye disease (Leber's hereditary optic atrophy), a type of epilepsy (called MERRF which stands for Myoclonus Epilepsy with Ragged Red Fibres), and a cause of dementia (called MELAS for Mitochondrial Encephalopathy, Lactic Acidosis and Stroke-like episodes). All mitochondrial diseases were entirely enigmatic before it was discovered that they were due to mutations not in regular chromosomes but the mitochondrial chromosome. (12 Dec 1998) |
| DNA, mitochondrial | Double-stranded DNA of mitochondria. In eukaryotes, the mitochondrial genome is circular and codes for ribosomal rnas, transfer rnas, and about 10 proteins. (12 Dec 1998) |
| acute inclusion body encephalitis | The most common acute encephalitis, caused by HSV-1; affects persons of any age; preferentially involves the inferomedial portions of the temporal lobe and the orbital portions of the frontal lobes; pathologically, severe haemorrhagic necrosis is present along with, in the acute stages, intranuclear eosinophilic inclusion bodies in the neurons and glial cells. Synonym: acute inclusion body encephalitis, herpes encephalitis. (05 Mar 2000) |
| conjunctivitis, inclusion | An infection of the eyes characterised by the presence in conjunctival epithelial cells of inclusion bodies indistinguishable from those of trachoma. It is acquired by infants during birth and by adults from swimming pools. The aetiological agent is chlamydia trachomatis whose natural habitat appears to be the genito-urinary tract. Inclusion conjunctivitis is a less severe disease than trachoma and usually clears up spontaneously. (12 Dec 1998) |
| Cowdry's type A inclusion bodies | Droplet-like masses of acidophilic material surrounded by clear halos within nuclei, with margination of chromatin on the nuclear membrane. (05 Mar 2000) |
| Cowdry's type B inclusion bodies | Droplet-like masses of acidophilic material surrounded by clear halos within nuclei, without other nuclear changes during early stages of development of the inclusion. (05 Mar 2000) |
| myositis, inclusion body | A progressive inflammatory myopathy primarily involving muscles of the pelvic region and legs, usually seen in older people. The muscles are infiltrated by mononuclear inflammatory cells, sarcoplasmic vacuoles, masses of filaments and filamentous microtubules, and sometimes eosinophilic bodies. (12 Dec 1998) |
| cytomegalic inclusion disease | <disease> An illness in newborns caused by viral infection, symptoms includefever, cellular enlargement, microscopically-visible clumps of viralparticles or proteins in the cytoplasm and nuclei of affected cells, enlargementof the spleen and liver. Long-term effects of the disease may includemental retardation. (09 Oct 1997) |
| cytoplasmic inclusion bodies | See: inclusion bodies. (05 Mar 2000) |
| psittacosis inclusion bodies | Intracytoplasmic chlamydial microcolonies observed in bronchial epithelial cells infected with Chlamydia psittaci. (05 Mar 2000) |
| subacute inclusion body encephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| nuclear inclusion bodies | See: inclusion bodies. (05 Mar 2000) |
| inclusion | 1. The act of including, or the state of being included; limitation; restriction; as, the lines of inclusion of his policy. 2. <chemical> A foreign substance, either liquid or solid, usually of minute size, inclosed in the mass of a mineral.
