| 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) |
| pseudotubular degeneration | A form of degeneration observed in adrenal glands, especially those of patients with febrile infectious disease; the shrunken, lipid-depleted cells of the zona fasciculata (and sometimes the zona glomerulosa) are arranged in a circular pattern about spaces that may be empty or partly filled with fibrin, necrotic cells, or amorphous material. (05 Mar 2000) |
| secondary degeneration | <medicine> A form of degeneration occurring in nerve fibres as a result of their division; so called from Dr. Waller, who published an account of it in 1850. Source: Websters Dictionary (01 Mar 1998) |
| senile degeneration | The process of involution occurring in old age. (05 Mar 2000) |
| hyaline degeneration | A group of several degenerative processes that affect various cells and tissues, resulting in the formation of rounded masses ("droplets") or relatively broad bands of substances that are homogeneous, translucent, refractile, and moderately to deeply acidophilic; may occur in the collagen of old fibrous tissue, smooth muscle of arterioles or the uterus, and as droplets in parenchymal cells. (05 Mar 2000) |
| hyaline degeneration of the elastic tissue of the arterial wall | Seen during involution of the uterus. (05 Mar 2000) |
