|---|---|---|---|
| 설명 | 면역이란 자신의 것과 자신의 것이 아닌 것을 구분해서 자신의 것이 아닌 것을 공격하여 생물학적 활성을 없애거나 제거하는 것이다. 이 면역은 주로 혈액에 있는 세포에 의해서 이루어진다. 특히 림프구는 이 면역에 중추적인 역할을 하는 세포이다. 이식편대숙주반응이라는 것은 이식되어온 조직에 존재하는 타인의 혈구들이 숙주의 세포를 공격하는 것을 말한다. 즉 이식되어온 조직과 함께 들어온 혈구들이 이식을 받은 사람의 세포를 타인의 것으로 인지해서 공격하는 현상이다. 이것은 이식을 받은 사람의 면역상태가 정상적일 경우에는 일어나지 않는데 왜냐하면 면역상태가 정상일 경우에는 이식되어온 장기와 더불어 들어온 타인의 혈구들을 이식을 받은 사람의 혈구가 타인의 것으로 인지해서 공격을 하고 숫적으로 유리하여 모두 죽일 수가 있기 때문이다. |

| DNAse i hypersensitivity site | <molecular biology> A site on a DNA molecule that is especially prone to being cut apart by the endonuclease enzyme DNase I, which breaks down DNA into smaller fragments by cleaving phosphodiester bonds. These sites tend to be near active genes, which are regularly transcribed. (09 Oct 1997) |

| drug hypersensitivity | Immunologically mediated adverse reactions to medicinal substances used legally or illegally. (12 Dec 1998) |
| tuberculin-type hypersensitivity | A local or generalised response that begins 24 to 48 hours after exposure to an antigen. See: cell-mediated reaction. Synonym: contact hypersensitivity, delayed hypersensitivity, late reaction, tuberculin-type hypersensitivity. (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) |
