| type III hypersensitivity reaction | An immunologic category of diseases evoked by the deposition of antigen-antibody or antigen-antibody-complement complexes on cell surfaces, with subsequent involvement of breakdown products of complement, platelets, and polymorphonuclear leukocytes, and development of vasculitis; nephritis is common. Arthus phenomenon and serum sickness are classic examples, but many other disorders, including most of the connective tissue disease's, may belong in this immunologic category; immune complex disease's can also occur during a variety of disease's of known aetiology, such as subacute bacterial endocarditis. See: autoimmune disease. Synonym: immune complex disorder, type III hypersensitivity reaction. (05 Mar 2000) |

| food hypersensitivity | Gastrointestinal disturbances, skin eruptions, or shock due to allergic reactions to allergens ingested in food. (12 Dec 1998) |
| genes, immediate-early | Genes that show rapid and transient expression in the absence of de novo protein synthesis. The term was originally used exclusively for viral genes where immediate-early referred to transcription immediately following virus integration into the host cell. It is also used to describe cellular genes which are expressed immediately after resting cells are stimulated by extracellular signals such as growth factors and neurotransmitters. (12 Dec 1998) |
| denture, complete, immediate | A complete denture constructed for replacement of natural teeth immediately after their removal. It does not fit the mouth perfectly and is intended only for functional and cosmetic purposes during the healing process after total extraction. It is to be replaced by the fitted permanent denture. (12 Dec 1998) |
| denture, partial, immediate | A partial denture constructed before the teeth it replaces are removed. It is then inserted immediately after the removal of the natural teeth for functional and cosmetic reasons during the healing process. It is to be replaced later by the fitted partial denture. (12 Dec 1998) |
| immediate | 1. Not separated in respect to place by anything intervening; proximate; close; as, immediate contact. "You are the most immediate to our throne." (Shak) 2. Not deferred by an interval of time; present; instant. "Assemble we immediate council." "Death . . . Not yet inflicted, as he feared, By some immediate stroke." (Milton) 3. Acting with nothing interposed or between, or without the intervention of another object as a cause, means, or agency; acting, perceived, or produced, directly; as, an immediate cause. "The immediate knowledge of the past is therefore impossible." (Sir. W. <surgery> Hamilton) Immediate amputation, an amputation performed within the first few hours after an injury, and before the the effects of the shock have passed away. Synonym: Proximate, close, direct, next. Origin: F. Immediat. See In- not, and Mediate. Source: Websters Dictionary (01 Mar 1998) |
| immediate allergy | A type I allergic reaction; so called because in a sensitised subject the reaction becomes evident usually within minutes after contact with the allergen (antigen), reaches its peak within an hour or so, then rapidly recedes. See: immediate reaction, anaphylaxis. Compare: delayed allergy. (05 Mar 2000) |
| immediate amputation | Amputation necessitated by irreparable injury to the limb, performed within twelve hours after the injury. (05 Mar 2000) |
| immediate contagion | Direct contagion occurring as the result of actual contact with the sick. (05 Mar 2000) |
| immediate denture | A complete or partial denture constructed for insertion immediately following the removal of natural teeth. Synonym: immediate insertion denture. (05 Mar 2000) |
| immediate early gene | Class of genes whose expression is low or undetectable in quiescent cells, but whose transcription is activated within minutes after extracellular stimulation such as addition of a growth factor. C fos and c myc proto-oncogenes were among the first IEG's to be identified. Many IEG's encode transcription factors and therefore have a regulatory function. (18 Nov 1997) |
| immediate-early proteins | Proteins that are coded by immediate-early genes, in the absence of de novo protein synthesis. The term was originally used exclusively for viral regulatory proteins that were synthesised just after viral integration into the host cell. It is also used to describe cellular proteins which are synthesised immediately after the resting cell is stimulated by extracellular signals. (12 Dec 1998) |
| immediate flap | A flap raised completely and transferred at the same stage. Synonym: immediate flap. (05 Mar 2000) |
| immediate insertion denture | A complete or partial denture constructed for insertion immediately following the removal of natural teeth. Synonym: immediate insertion denture. (05 Mar 2000) |
| immediate percussion | The striking of the part under examination directly with the finger or a plessor, without the intervention of another finger or plessimeter. Synonym: direct percussion. (05 Mar 2000) |
