| 영문 | mast cell | 한글 | 비만 세포 |
|---|---|---|---|
| 설명 | 동물의 결합 조직 가운데 널리 분포하는 세포. 결합조직과 점막조직 내에 있는 호염기성 색소로 이염색성(metachromasia)을 나타내는 과립을 가진 방추형의 세포에 작은 둥근 핵을 가진다. 비만세포의 표면에는 IgE에 대한 수용체가 존재하며, 수용체에 결합한 IgE 분자들끼리 다가의 항원에 의해 서로 연결되면 비만세포 과립탈출 반응이 일어나, 히스타민, 세로토닌, 헤파린 등의 화학전달 물질이 방출되어, 즉시형 알레르기 반응 등의 증상을 일으킨다. 피부, 장막, 혈관 주위, 점막 주변에 있다. |

| 영문 | cell-mediated immunity | 한글 | 세포매개면역 |
|---|---|---|---|
| 설명 | 면역이란 신체를 외부의 물질로부터 보호하는 행위를 말한다. 여기에는 특이적 면역과 비특이적 면역의 두 가지가 있다. 비특이적 면역이라함은 특정한 물질에 관계하는 면역이 아니라 특정 대상이 없이 모든 외부 물체에 작용할 수 있는 면역을 말한다. 여기에는 소변의 흐름, 눈물의 흐름, 피부의 비투과성 등의 기계적인 것도 포함되고 피속에 돌아다니는 세포 중에서 비특이적으로 외부의 물질을 포식하는 세포들(예를 들면 큰포식세포(macrophage)의 활동도 포함이 된다. 세포매개면역이란 특이한 물질을 감지할 수 있는 세포를 생성하게 하여 그것으로 하여금 그 물질을 포식하게 하는 것을 말한다. |

| 영문 | nerve cell | 한글 | 신경세포 |
|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

| 영문 | glia cell | 한글 | 아교세포 |
|---|---|---|---|
| 설명 | 신경세포 사이에서 그물구조를 이루며 이를 지지하는 조직. 신경아교세포는 신경모세포와 갈라진 아교모세포가 다시 여러 형태로 분화-성장한 것이다. 뇌실이나 척수중심관의 벽을 덮고 원주상 또는 입방형이며, 초기에는 유리면에 섬모가 있다. 대형세포는 별뇌실막세포는 아교세포라고 하며, 신경세포나 신경섬유 사이에 산재한다. 그 외에 희소돌기아교세포도 포함된다. |

|---|---|
| transient global amnesia | A memory disorder seen in middle aged and elderly persons characterised by an episode of amnesia and bewilderment which persists for several hours; during the episode the patient has a memory defect for present and recent past events, but is fully alert, oriented, capable of high-level intellectual activity, and has a normal neurological examination. Typically, these amnesic episodes occur spontaneously, and most patients experience only one; of uncertain aetiology-probably ischemic, but not due to atherosclerosis. (05 Mar 2000) |
| transient hypogammaglobulinaemia of infancy | A type of primary immunodeficiency that occurs in infants of both sexes, usually before the sixth month of life, probably resulting from immaturity of lymphoid tissue. Synonym: transient agammaglobulinaemia. (05 Mar 2000) |
| transient ischaemic attack | A transient ischaemic attack is a temporary paralysis, numbness, speech difficulty or other neurologic symptoms that start suddenly and recovers within 24 hours (typically resolve over several hours). See: neurologic symptoms, stroke. Acronym: TIA (26 Mar 1998) |
| transient ischemic attack | A sudden focal loss of neurological function with complete recovery usually within 24 hours; caused by a brief period of inadequate perfusion in a portion of the territory of the carotid or vertebral basilar arteries. (05 Mar 2000) |
| transient retinopathy | Transient traumatic retinal angiopathy due to a sudden rise in venous pressure, as in compression of the body from seat belt injury; ocular fundi show large white patches associated with the retinal veins about the disk or macula, haemorrhages, and retinal oedema; thought to be due to fat embolism from bone marrow. Synonym: Purtscher's disease, transient retinopathy, traumatic retinopathy. (05 Mar 2000) |
| epidemic transient diaphragmatic spasm | An acute infectious disease usually occurring in epidemic form, characterised by paroxysms of pain, usually in the chest, and associated with strains of Enterovirus coxsackievirus type B.
