|---|---|---|---|
| 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. |

| delayed graft | Application of a skin graft after waiting several days for healthy granulations to form. (05 Mar 2000) |
|---|---|
| delayed hypersensitivity | <immunology> Hypersensitivity (increased reaction by the body to a foreign substance such as an antigen or allergen) that does not appear until 24 to 48 hours after the body is exposed to the foreign substance. (09 Oct 1997) |
| delayed implantation | A phenomenon characterised by an interval ranging from a few weeks to approximately 6 months between the time an ovum is fertilised and subsequent implantation of the zygote, as in the marten and the armadillo. (05 Mar 2000) |
| delayed rectifier channel | <physiology> The potassium selective ion channels of axons, so called because they change the potassium conductance with a delay after a voltage step. The name is used to denote any axon like K channel. Various roles for example regulation of pacemaker potentials, generation of bursts of action potentials or generation of long plateaus on action potentials. (18 Nov 1997) |
| delayed reflex | A reflex in which a little time elapses between stimulus and response. See: trace conditioned reflex. (05 Mar 2000) |
| delayed sensation | A sensation that is not perceived until the lapse of an appreciable interval following the application of the stimulus. General sensation, a sensation referred to the body as a whole rather than to any particular part. (05 Mar 2000) |
| delayed suture | A suturing of a wound after an interval of days. (05 Mar 2000) |
| delayed type hypersensitivity | <immunology> Hypersensitivity (increased reaction by the body to a foreign substance such as an antigen or allergen) that does not appear until 24 to 48 hours after the body is exposed to the foreign substance. (09 Oct 1997) |
| ovum implantation, delayed | Delay of embryonal development whereby the blastocyst remains in the uterine cavity for a variable period of time before attaching to the endometrium and continuing its development. (12 Dec 1998) |
| acute extrinsic allergic alveolitis | <radiology> No chest X-ray findings in 30-95%, diffuse acinar consolidative pattern (oedema and exudative filling of alveoli), basilar distribution, lymph node enlargement (unusual, more common with recurrence) see: extrinsic allergic alveolitis (12 Dec 1998) |
| allergic | <immunology> Pertaining to, caused by, affected with or of the nature of allergy. (18 Nov 1997) |
| allergic alveolitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
| allergic angiitis | An acute form of vasculitis which may affect the skin only, but also may involve other organs, with a polymorphonuclear infiltrate in the walls of and surrounding small (dermal) vessels. Nuclear fragments are formed by karyorrhexis of the neutrophils. See: leukocytoclastic vasculitis. Synonym: allergic angiitis, hypersensitivity vasculitis. (05 Mar 2000) |
| allergic asthma | <chest medicine> A disease process that is characterised by paradoxical narrowing of the bronchi (lung passageways) making breathing difficult. Treatment includes bronchodilators which are given orally or delivered as an aerosol (inhaled). Corticosteroids are reserved for more difficult cases. Symptoms include wheezing, difficulty breathing (particularly exhaling air) and tightness in the chest. Factors which can exacerbate asthma include rapid changes in temperature or humidity, allergies, upper respiratory infections, exercise, stress or smoke (cigarette). See: status asthmaticus. (27 Sep 1997) |
| allergic bronchopulmonary aspergillosis | <radiology> ABPA: Aspergillus fumigatus hypersensitivity, mucoid impaction of bronchi distal to lobar bronchus, mucus plugs contain fungi, eosinophils, XR: Y-shaped density (mucus plug wedged in bronchi) (12 Dec 1998) |
