|---|---|---|---|
| 설명 | 원형질 표면을 덮는 엷은막. 두께는 5~25μm이다. 광학현미경으로는 관찰할 수 없지만 전자현미경으로 관찰이 가능하다. 원형질막의 분자구조는 레시틴이나 콜레스테롤 등의 표면 활성물질 분자가 2분자층으로 그 표면에 배열되며, 이것을 각 1분자층의 단백질 분자가 양쪽에서 샌드위치한 단위막 구조이다. 전자현미경적으로 이 단위는 암-명-암의 3층(각 약 20nm)으로 구별된다. 원형질의 투과성에 중요한 구실을 하며, 생리상태가 변하면 그 투과성도 신속히 변한다. 또, 손상이 되면 쉽게 새로 형성된다. |

| antibody-forming cell | <immunology> B-cells (plasma cells) that are dedicated to producing secreted antibodies. (09 Feb 1998) |
|---|---|
| antibody induced lysis | <haematology> The term is imprecise and should not be used since there is confusion as to which mechanism is involved, i.e. Natural killing or complement lysis. See: complement lysis, natural killer cells. (09 Feb 1998) |
| antibody producing cell | <immunology> A lymphocyte of the B series synthesising and releasing immunoglobulin. Equivalent to plasmacyte and plasma cell. (18 Nov 1997) |
| antibody-producing cells | Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesise. (12 Dec 1998) |
| antibody specificity | The property of antibodies which enables them to react with some antigenic determinants and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site. (12 Dec 1998) |
| antibody technology | <molecular biology> Techniques for the synthesis of polyclonal and monoclonal antibodies for use in research, diagnostics and therapeutics. (09 Feb 1998) |
| antigen-antibody complex | The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes immune complex diseases. If the antigen is polyvalent the complex may be insoluble. Immune complexes activate complement through the classical pathway. See: glomerulonephritis, Arthus reaction, type III hypersensitivity. (12 Dec 1998) |
| antigen-antibody reaction | The phenomenon, occurring in vitro or in vivo, of antibody combining with antigen of the type that stimulated the formation of the antibody, thereby resulting in agglutination, precipitation, complement fixation, greater susceptibility to ingestion and destruction by phagocytes, or neutralization of exotoxin. See: skin test. (05 Mar 2000) |
| anti-idiotype antibody | <immunology> An antibody directed against the antigen specific part of the sequence of an antibody or T-cell receptor and thus recognise the binding sites of other antibodies. In principle an anti-idiotype antibody should inhibit a specific immune response and they are important to the regulation of the immune system. (13 Nov 1997) |
| anti-insulin antibody | A serologic blood test that is used to detect antibodies to insulin. This test is performed in insulin dependent diabetics who exhibit insulin resistance. The presence of antibodies denotes a positive result. (27 Sep 1997) |
| antinuclear antibody | <immunology> Antinuclear antibody is an antibody that react against components of the cell nucleus such as DNA, RNA, histone or non-histone proteins. These antibodies are present in a variety of immunologic or autoimmune diseases including systemic lupus erythematosus, systemic sclerosis, scleroderma, Sjogren's syndrome, rheumatoid arthritis, polymyositis, dermatomyositis and in persons taking hydralazine, procainamide or isoniazid. A serologic measurement for antinuclear antibodies can aid in the diagnosis of unexplained arthritis, rashes or chest pains. Acronym: ANA (12 Jan 1998) |
| anti-P antibody | <haematology, investigation> A serologic blood test used to detect the Donath-landsteiner antibody in serum. This test is performed in cases of suspected paroxysmal cold haemoglobinuria. A normal result is indicated by an absence of antibodies. The antibody is directed toward the P-antigen complex which is located on the surface of red blood cells. In some way, cold temperatures trigger the antibody to bind to this site. (13 Jan 1998) |
| antiparietal cell antibody | <immunology> A serologic blood test which measures the presence of antibodies to gastric parietal cells. Less than 2% of the general population will be antibody positive although this can be higher in the elderly. Approximately 90% of individuals with pernicious anaemia will be antibody positive. A positive result may also be seen in atrophic gastritis, gastric ulcer, thyroid disease, iron deficiency anaemia and diabetes. (13 Jan 1998) |
| antiphospholipid antibody | <immunology, syndrome> An uncommon disorder that is characterised by hypercoagulability due to the presence of antibodies against phospholipids. These patients exhibit a tendency for recurrent and life-threatening thrombosis and embolic events (for example stroke). Individuals with antiphospholipid syndrome also have an increased tendency toward deep venous thrombosis, myocardial infarction and spontaneous abortions in females. Antiphospholipid syndrome may be seen by itself or in association with other autoimmune illnesses (for example lupus) or with some infections. Treatment includes long-term heparin and warfarin. (13 Jan 1998) |
| antiphospholipid antibody syndrome | <syndrome> An immune disorder characterised by the presence of abnormal antibodies in the blood associated with certain medical conditions including abnormal blood clotting, migraine headaches, premature miscarriage, and low blood platelet counts (thrombocytopenia).
