| 영문 | graft versus host reaction | 한글 | 이식편대 숙주반응 |
|---|---|---|---|
| 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. |

| Roger-Anderson pin fixation appliance | An appliance used in extraoral fixation of mandibular fractures and prognathic corrections in which pins placed in the bone segments are joined by metal connecting rods. See: external pin fixation. (05 Mar 2000) |

| circumalveolar fixation | Stabilization of a fracture segment or surgical splint by wire passed through and around the dental alveolar process. (05 Mar 2000) |
| circummandibular fixation | Stabilization of a fracture segment or surgical splint by wire passed around the mandible. (05 Mar 2000) |
| circumzygomatic fixation | Stabilization of a fracture segment or surgical splint by wire passed around the zygomatic arch. (05 Mar 2000) |
| complementation-fixation test | <investigation> A test for the presence of antibodies in a serum, based on whether an antigen and complement, when put together with some red blood cells, are able to destroy them. If the red blood cells are destroyed, then antibodies were not present to prevent it. If the red blood cells are not destroyed, then antibodies were present to combine with the antigen and bind the complement, making them unable to attack the red blood cells. (09 Oct 1997) |
| point of fixation | The point on the retina at which the rays coming from an object regarded directly are focused. Synonym: point of regard. (05 Mar 2000) |
| craniofacial fixation | Stabilization of facial fractures to the cranial base by direct wiring or by external skeletal pin fixation. (05 Mar 2000) |
| crossed fixation | In convergent strabismus, the use of the right inturned eye to look at objects to the left and the left inturned eye to look at objects to the right, in order to avoid ocular rotation. (05 Mar 2000) |
| crossover fixation | <molecular biology> The addition of extra copies of segments of DNA on the same strand by unequal crossing over during meiosis. An explanation for the existence of satellite DNA, which are highly-repeated, non-transcribed sequences of DNA with no clear function. An alternative explanation to saltatory replication. (03 Jul 1999) |
| nasomandibular fixation | Mandibular immobilization, especially for edentulous jaws, with maxillomandibular splints, attached by connecting a circum-mandibular wire with an intraoral interosseous wire passed through a hole drilled into the anterior nasal spine of the maxillae. (05 Mar 2000) |
| nitrogen fixation | <biochemistry> The incorporation of atmospheric nitrogen into ammonia by various bacteria, catalysed by nitrogenase. This is an essential stage in the nitrogen cycle and is the ultimate source of all nitrogen in living organisms. In the sea, the main nitrogen fixers are Cyanobacteria. There are several free living bacteria in soil that fix nitrogen including species of Azotobacter, Clostridium and Klebsiella. Rhizobium only fixes nitrogen when in symbiotic association, in root nodules, with leguminous plants. The oxygen sensitive nitrogenase is protected by plant produced leghaemoglobin and the plant obtains fixed nitrogen from the bacteria. See: Frankia. (18 Nov 1997) |
| intermaxillary fixation | Fixation of fractures of the mandible or maxilla by applying elastic bands or stainless steel wire between the maxillary and mandibular arch bars or other types of splint. Synonym: mandibulomaxillary fixation, maxillomandibular fixation. (05 Mar 2000) |
| internal fixation | The use of internal metal plates, screws or rods to stabilise bone fragments. A procedure used to correct serious orthopaedic bone fractures that cannot be stabilised by casting or splinting. See: external fixation. (27 Sep 1997) |
| intraosseous fixation | The use of internal metal plates, screws or rods to stabilise bone fragments. A procedure used to correct serious orthopaedic bone fractures that cannot be stabilised by casting or splinting. See: external fixation. (27 Sep 1997) |
