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

| 영문 | reserve cell | 한글 | 예비세포 |
|---|---|---|---|
| 설명 | 일반적으로 상피조직에서 이미 있던 상피세포가 손상을 받아 사멸하면 매꿔지는 그 밑에 있는 미분화세포 예를 들면, 기관지 내표면을 덮는 중층 원주 상피의 기저에 있는 작은 미분화 상피 세포. |

| 영문 | stem cell | 한글 | 줄기세포, 간세포 |
|---|---|---|---|
| 설명 | 자기 복제를 하여 자신을 존속시키면서 한편으로는 증식과 분화를 하여 새로운 세포를 형성하는 세포로서 조혈줄기세포가 대표적이다. 조혈줄기세포는 골수에 있는 세포로서 모든 혈구세포가 여기에서 분화되어 발생한다. |

| Nairobi sheep disease virus | An unclassified arbovirus of the family Bunyaviridae causing Nairobi sheep disease, transmitted by the tick, Rhipicephalus appendiculatus; it is a serologic group of virus's morphologically like Bunyavirus but antigenically unrelated to it. (05 Mar 2000) |
|---|---|
| nairobi sheep disease viruses | A group of viruses of the genus nairovirus, transmitted by the ixodid ticks and producing a lethal gastroenteritis in sheep and goats, especially in africa. Though major veterinary pathogens, their effect on humans has not been firmly established. (12 Dec 1998) |
| infectious necrotic hepatitis of sheep | A disease of sheep caused by the bacterium Clostridium novyi, which invades livers damaged by the fluke Fasciola hepatica and causes severe necrosis and death; this disease occurs in nearly all parts of the world, including the U.S. Sometimes called black disease because of the extensive haemorrhages seen on the inner surface of the pelt when it is removed. Synonym: black disease. (05 Mar 2000) |
| Eimeria of sheep and goats | Eimeria ovina (arloingi), the most common and destructive species in sheep, principal losses being in young lambs; Eimeria minakolyakimovae, a highly pathogenic parasite of sheep; Eimeria parva and Eimeria pallida are frequently found but believed to be of low virulence; Eimeria faurei, Eimeria intricata, Eimeria granulosa, Eimeria ahsata, Eimeria hawkins, Eimeria gilruthi, Eimeria gonzalezi, Eimeria christenseni, Eimeria punctata, Eimeria crandallis, and Eimeria honessi, are found in sheep or goats, and are probably of low pathogenicity. All of these species invade the epithelium of the small intestine. Synonym: coccidia of sheep and goats. (05 Mar 2000) |
| Kisenyi sheep disease virus | A virus, in the family Bunyaviridae, that is probably the same as Nairobi sheep disease virus. (05 Mar 2000) |
| acid agglutination | The clumping together of certain microorganisms at high hydrogen ion concentration. (05 Mar 2000) |
| agglutination | <cell biology, haematology> The clumping together of cells due to the binding of agglutinin (a protein) molecules on the surface of each cell. The clumping together of two organisms of the same species for the purpose of sexual reproduction. Often conducted by means of acarbohydrate on one organism and a protein on theother, resulting in a glycoprotein. (06 May 1997) |
| bacteriogenic agglutination | The clumping of erythrocytes as a result of effects of bacteria or their products. (05 Mar 2000) |
| passive agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| group agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
| mixed agglutination | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |
| mixed agglutination reaction | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |
| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25캜; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |
| cross agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
