| 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. |

| 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. |

| direct nuclear division | <cell biology> An unusual form of nuclear division, in which the nucleus simply constricts, rather like a cell without chromosome condensation or spindle formation. Partitioning of daughter chromosomes is haphazard. Observed in some Protozoa. (18 Nov 1997) |
|---|---|
| division | 1. The act of dividing. 2. <zoology> A rank that if treated as a division of a genus or subgenus is deemed to be of subgeneric rank for the purposes of nomenclature. 3. A taxon at the rank of division. The second highest taxonomic classification for the kingdoms Plantae (plants) and Fungi, between kingdom level and class level. (09 Jan 1998) |
| division septum | <cell biology> The cell wall that forms between daughter cells at the end of mitosis in plant cells or just before separation in bacteria. (18 Nov 1997) |
| equatorial division | Nuclear division in which each chromosome divides equally. (05 Mar 2000) |
| first meiotic division | The first of two consecutive divisions of the nucleus of an eukaryotic cell during the process of meiosis. It includes the following stages of meiosis: prophase I, metaphase I, anaphase I, and telophase I. (09 Oct 1997) |
| calorimetry, indirect | Calculation of the energy expenditure in the form of heat production of the whole body or individual organs based on respiratory gas exchange. (12 Dec 1998) |
| indirect | 1. Not immediate or straight. 2. Acting through an intermediary agent. Origin: L. Indirectus (18 Nov 1997) |
| 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) |
| indirect assay | For antibody; an application of the ELISA method in which serum being tested for antibody is added to wells coated with known antigen; presence of antibody bound to the antigen coat can be determined by addition of immunoglobulin-specific antibody to which is linked the enzyme of the indicator system, followed by addition of substrate to the washed aggregate. (05 Mar 2000) |
| indirect bilirubin | <biochemistry> Free bilirubin that has not been attached to a glucuronide molecule. This results from the rapid breakdown of red blood cells. The haemoglobin molecule is normally converted to bilirubin. Greater than normal values of indirect bilirubin can be seen in erythroblastosis foetalis, haemolytic anaemia, sickle cell anaemia, transfusion reactions, pernicious anaemia and resolution of large haematomas. (27 Sep 1997) |
| indirect Coombs' test | A test routinely performed in cross-matching blood or in the investigation of transfusion reaction: test for patient's serum is incubated with a suspension of donor erythrocytes; if specific antibodies are present, they become attached to the antigen in donor's cells; after a washing with saline, Coombs' antihuman globulin is added; agglutination at this point indicates that antibodies present in the original test serum had indeed become attached to donor erythrocytes. (05 Mar 2000) |
| indirect diuretic | A diuretic that acts by increasing cardiac function or by increasing the state of hydration. (05 Mar 2000) |
| indirect fluorescent antibody | The detection of antibodies to specific antigenic material in the substrate using fluorescent microscopy. Using fluorescent conjugated antibodies which are specific for a particular isotype of antibody, it is possible to distinguish IgG, IgA and IgM isotypes of specific antibodies using indirect fluorescent antibody. This sensitive technique is highly specific in well-trained hands and recent developments in the establishment of internationally recognised standard materials have led to accurate quantitation of antibody concentrations through endpoint titration (the highest serial dilution of specimen at which specific fluorescence remains) and through measuring visual intensity of fluorescence compared to known reference standard material. (05 Mar 2000) |
| indirect fracture | A fracture, especially of the skull, that occurs at a point not at the site of impact. (05 Mar 2000) |
| indirect haemagglutination test | A kind of passive agglutination in which erythrocytes, usually modified by mild treatment with tannic acid or other chemicals, are used to adsorb soluble antigen onto their surface, and which then agglutinate in the presence of antiserum specific for the adsorbed antigen. Synonym: indirect haemagglutination test. (05 Mar 2000) |
