| colloid degeneration | A degeneration similar to mucoid degeneration, in which the material is inspissated. (05 Mar 2000) |
|---|---|
| mucinoid degeneration | A term including both mucoid and colloid degeneration, the essential cellular changes in both being similar, the only difference being that, in colloid degeneration, the substance is firmer and more inspissated than in mucoid degeneration, in which it is thin and jelly-like. (05 Mar 2000) |
| mucoid degeneration | A conversion of any of the connective tissues into a gelatinous or mucoid substance. Synonym: myxoid degeneration, myxomatous degeneration, myxomatosis. (05 Mar 2000) |
| mucoid medial degeneration | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| cone degeneration | A retinal abnormality in which colour perception is severely deficient and typical changes occur in electroretinogram. See: achromatopsia. Synonym: cone degeneration. (05 Mar 2000) |
| myelinic degeneration | Formation of myelin figures in the cytoplasm of cells, possibly by degradation or hydration of lipoprotein of self-digested organelles. (05 Mar 2000) |
| myopic degeneration | Association of crescent of the optic disk, atrophy of the choroid and macular pigment, subretinal neovascularization, haemorrhage, and pigment proliferation in pathologic myopia. (05 Mar 2000) |
| myxoid degeneration | A conversion of any of the connective tissues into a gelatinous or mucoid substance. Synonym: myxoid degeneration, myxomatous degeneration, myxomatosis. (05 Mar 2000) |
| Crooke's hyaline degeneration | Replacement of cytoplasmic granules of basophil cells of the anterior pituitary by homogenous hyaline material; a characteristic finding in Cushing's syndrome, but usually not present in the cells of a basophil adenoma. Synonym: Crooke's hyaline degeneration. (05 Mar 2000) |
| primary neuronal degeneration | <disease> A progressive, neurodegenerative disease characterised by loss of function and death of nerve cells in several areas of the brain leading to loss of cognitive function such as memory and language. The cause of nerve cell death is unknown but the cells are recognised by the appearance of unusual helical protein filaments in the nerve cells (neurofibrillary tangles) and by degeneration in cortical regions of brain, especially frontal and temporal lobes. Alzheimer's disease is the most common cause of dementia. (22 May 1997) |
| primary pigmentary degeneration of retina | A hereditary disorder of the retina mainly affecting photoreceptors and retinal pigment epithelium; a miscellaneous category including Friedreich's ataxia, Refsum's disease, and abetalipoproteinaemia. Synonym: primary pigmentary degeneration of retina. (05 Mar 2000) |
| primary progressive cerebellar degeneration | A familial ataxic condition related to cerebellar degeneration. (05 Mar 2000) |
| Salzmann's nodular corneal degeneration | Large and prominent nodules of a solid, opaque material that stands out from the surface of the cornea; occurs occasionally in persons previously affected by phlyctenular keratitis. (05 Mar 2000) |
| hepatolenticular degeneration | <gastroenterology, neurology> An inherited disorder where there is excessive quantities of copper in the tissues, particularly the liver and central nervous system. Wilson's disease causes the body to absorb and retain copper. The copper deposits in the liver, brain, kidneys and eyes. Complications include dementia and liver failure. Symptoms include jaundice, vomiting, tremors, weakness and slow stiff movements. Blood tests show serum ceruloplasmin is low. Medications are given to remove the excess copper from the body. Even with life-long treatment, disabling (and life-threatening) side effects are common. Inheritance: autosomal recessive. (27 Sep 1997) |
| xerotic degeneration | Scarring of the conjunctiva associated with keratinised epithelium. (05 Mar 2000) |
