| 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 hypersensitivity | An exaggerated immune response mediated by antibodies, in particular IgE. See: allergy. (05 Mar 2000) |
| immediate hypersensitivity reaction | An immune response mediated by antibody, usually IgE, which occurs within minutes after a second encounter with an antigen, resulting in the release of histamine and subsequent swelling and vasodilation. (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) |
| immediate posttraumatic automatism | A posttraumatic state in which the patient performs automatically without immediate or later memory of that behaviour. (05 Mar 2000) |
| immediate posttraumatic convulsion | A convulsion beginning very soon after injury. (05 Mar 2000) |
| immediate reaction | Local or generalised response that begins within a few minutes to about an hour after exposure to an antigen to which the individual has been sensitised. See: skin test, wheal-and-erythema reaction. Synonym: early reaction. (05 Mar 2000) |
| immediate transfusion | Transfusion of blood from the donor to the receptor, either through a tube connecting their blood or by suturing the vessels together. Synonym: immediate transfusion. (05 Mar 2000) |
