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

| 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. |

| TRCA | tanned red cell agglutination |
| 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) |
| cold agglutination test | <investigation> A test for blood antibodies which are present in certain peculiar types of pneumonia (atypical pneumonia, Mycoplasma) (27 Sep 1997) |
| 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) |
| sperm agglutination | Agglutination of spermatozoa. (05 Mar 2000) Previous: Spens, Thomas, spent, speract, sperling, sperm, spermaceti, spermacytic seminomaNext: sperm agglutination, spermalist, spermaphore, spermary, sperm-astersperm agglutination Agglutination of spermatozoa by antibodies or autoantibodies. (12 Dec 1998) |
| spontaneous agglutination | The non-specific clumping of organisms in saline related to lack of polar groups in electrolyte solution. (05 Mar 2000) |
| nonimmune agglutination | <haematology> Agglutination caused by a lectin having a degree of specificity, the mechanism of which is not understood, agglutination that results from non-specific factors, as in the case of acid agglutination or spontaneous agglutination. (05 Mar 2000) |
| direct agglutination | A general term for techniques which use the agglutination (macroscopic clumping) of particulate reagents as an indicator of the presence of an antigen-antibody reaction. Examples (haemagglutination, latex agglutination and coagglutination) follow. (05 Mar 2000) |
| immune agglutination | Agglutination caused by antibody (agglutinin) that is specific for the suspended microorganism, cell, or for an antigen that has been coated on a particle of suitable size. (05 Mar 2000) |
| indirect agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| false agglutination | 1. Agglomeration of particles in solution which does not involve antigen-antibody combination. Synonym: false agglutination. Synonym: rouleaux formation. (05 Mar 2000) |
| latex agglutination | Also known as latex particle agglutination, for detection of antibodies is identical to haemagglutination in principle, but the substitution of smaller, antigen-coated latex particles for erythrocytes results in improved sensitivity and reagent longevity. Alternatively, antibodies can be absorbed to the latex particles (under appropriate ionic and pH conditions) by binding to the Fc region of antibodies, leaving the Fab region free to interact with antigens present in the applied specimens. This phenomenon has made latex agglutination a popular technique for detecting antigens as well. (05 Mar 2000) |
