| necrotizing encephalitis | Any encephalitis in which extensive brain necrosis occurs, e.g., acute necrotizing haemorrhagic encephalomyelitis. (05 Mar 2000) |
|---|---|
| necrotizing encephalomyelopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
| necrotizing encephalopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
| necrotizing enterocolitis | <radiology> NEC, pneumatosis intestinalis, submucosal: initial finding, mult. Cystic lucencies; looks like stool (!), subserosal: linear lucencies, portal vein: with or without transient; not significant, aetiology: preemie, perinatal stress, intestinal ischemia, survivors may develop intestinal strictures (12 Dec 1998) |
| necrotizing papillitis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |
| necrotizing scleritis | Fibrinoid degeneration and necrosis of the sclera. (05 Mar 2000) |
| necrotizing ulcerative gingivitis | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |
| subacute necrotizing encephalomyelopathy | A rare fatal disorder, primarily of children, being both acute and chronic in onset, manifested primarily as brainstem dysfunction, with ataxia, cranial nerve palsies, pseudobulbar palsy, hemi-or quadriplegia, mental deterioration, and involuntary movements; deficiencies of pyruvate dehydrogenase or cytochrome C oxydase have been found in some patients; pathologically, there is widespread symmetric necrosis involving much of the brainstem; these changes are similar to those seen with Wernicke encephalopathy. (05 Mar 2000) |
| subacute necrotizing myelitis | A disorder of the lower spinal cord in adult males resulting in progressive paraplegia. Synonym: angiodysgenetic myelomalacia, Foix-Alajouanine myelitis. (05 Mar 2000) |
| disseminated necrotizing leukoencephalopathy | <radiology> DNL: demyelination due to radiation and chemotherapy, decreased density in deep white matter, with or without peripheral, patchy enhancement, calcification: basal ganglia, grey/white junction (12 Dec 1998) |
| ABO blood group | <haematology> The major human blood type system which describes the oligosaccharide glycoprotein antigens found on the surface of human blood cells. According to the type of antigen present, a person may be assigned a blood type of A, B, AB or O. A second type of antigen, the Rh factor, renders a positive or negative blood type. The ABO blood group system is important because it determines who can donate blood to or accept blood from whom. Type A or AB blood will cause an immune reaction in people with type B blood and type B and AB blood will cause a reaction in people with type A blood. Conversely, type O blood has no A or B antigens, so people with type O blood are universal donors. And since AB blood already produces both antigens, people who are type AB can accept any of the other blood types without suffering an immune reaction. (04 Jul 1999) |
| actinobacteria group | A group of gram-positive, heterogeneous bacteria. This group encompasses a range of morphologically, physiologically, and chemically different organisms and includes bacteria that form cocci, short rods, irregular rods, and mycelia that fragment. (12 Dec 1998) |
| alkyl group | <chemistry> A funtional group on an organic molecule which is derived from an alkane which has lost a hydrogen atom. (13 Nov 1997) |
| aluminum group | Aluminum, boron, gallium, indium, and thallium. (05 Mar 2000) |
| amino group | <biochemistry> An -NH2 group. Organic compounds which have this group are called amines. (09 Oct 1997) |
