| 설명 | 조절할 수 없이 계속 진행되는 세포분열에 의한 조직의 새로운 증식 및 증대. 신생물. (1) 분류 A. 침윤과 전이의 유무에 따라 i)양성종양: 침윤과 전이가 없고 역형성이 낮은 세포로 구성됨. 대개 치료에 반응이 높고, 생명에 크게 지장이 없으며, 재발하는 경우도 적다. 증상은 단지 주위조직에 대한 압박정도이다. ii)악성종양: 침윤과 전이가 있고 퇴화도가 높은 세포로 구성됨. 기원세포가 상피조직일 경우 암종, 비상피성일 경우 육종으로 나누기도 한다. 치료에 잘 반응하지 않고, 재발을 잘 하며, 생존율이 낮다. 흔히 말하는 “암”을 의미한다. B. 조직학적 특징에 따라 샘종, 지방종, 근종 등으로 나누기도 한다. (2) 병리조직학적 특징 A. 육안적 소견 덩어리를 형성하기도 하고 정상조직에 스며들듯이 판상구조를 이루기도 하는 등 다양한 형태를 보인다. 양성의 경우 피막을 가진 경우가 많고 악성의 경우 없는 경우가 많다. 육안소견에 따라 다음과 같이 나눈다. 낭성, 융기성, 괴사성, 폴립모양, 궤양형 등이 있다. 또는 세포의 크기와 모양이 비정상적인 형태로 변화한다. 핵의 극성이 사라지고 핵의 염색성이 짙어진다. 세포질의 염색성도 변화하며 세포들간의 세포주기가 매우 다양해져 많은 세포분열을 보인다. 이러한 일련의 변화를 역형성이라 한다. 역형성의 정도에 따라 조직학적 등급을 나눈다. 또한 각 종양에 따라 각기 다른 병리조직학적 명칭을 붙인다. |

| carcinoembryonic antigen | <tumour marker> Antigen found in blood of patients suffering from cancer of colon and some other diseases, that is otherwise normally found in foetal gut tissue. (19 Jan 1998) |
|---|---|
| macrophage-1 antigen | An adhesion-promoting leukocyte surface membrane heterodimer. The alpha subunit consists of the CD11b antigen and the beta subunit of the CD18 antigen (antigens, CD18). The antigen, which is an integrin, functions both as a receptor for complement 3 and in cell-cell and cell-substrate adhesive interactions. (12 Dec 1998) |
| V antigen | Viral antigen that is intimately associated with the virus particle, is protein in nature, has multiple antigenicities, and is strain-specific; antibody to such antigen is demonstrable as protective or neutralizing antibody. (05 Mar 2000) |
| variable antigen | <immunology> Term usually applied to the surface antigens of those parasitic or pathogenic organisms that can alter their antigenic character to evade host immune responses. (See antigenic variation). (18 Nov 1997) |
| G antigen | An antigenic glycoprotein frequently associated with viral surfaces. Origin: Ger. Gebundenes, bound (05 Mar 2000) |
| major histocompatibility antigen | <immunology> A set of plasmalemmal glycoprotein antigens involved in rapid (e.g. 7 days in the mouse) graft rejection and other immune phenomena. The minor histocompatibility antigens are involved in much slower rejection phenomena. The major antigens show remarkable polymorphism and occur as Class I and Class II types in mammals, birds may have a Class III molecule as well. See: histocompatibility antigens, MHC restriction. (18 Nov 1997) |
| P antigen | <haematology, immunology> Antigenic determinant on the surface of human red blood cells to which the Donath Landsteiner antibody reacts. This antibody binds in the cold (a cold IgG), but elutes from red cells at 37쵣, is particularly associated with tertiary syphylis and its binding causes paroxysmal nocturnal haemoglobinuria. (18 Nov 1997) |
| R antigen | Those that produce active haemolysins (O and S) which cause a zone of clear haemolysis on the blood agar medium in the area of the colony; beta-haemolytic streptococci are divided into groups (A to O) on the basis of cell wall C carbohydrate (see Lancefield classification); Group A (in the strains pathogenic for man) comprises more than 50 types (designated by Arabic numerals) determined by cell wall M protein, which seems to be associated closely with virulence and is produced chiefly by strains with matt or mucoid colonies, in contrast to nonvirulent, glossy colony-producing strains; other surface protein antigens such as R and T (T substance), and the nucleoprotein fraction (P substance) seem to be of less importance. The more than 20 extracellular substances elaborated by strains of beta-haemolytic streptococci include erythrogenic toxin (elaborated only by lysogenic strains), deoxyribonuclease (streptodornase), haemolysins (streptolysins O and S), hyaluronidase, and streptokinase. Synonym: haemolytic streptococci. (05 Mar 2000) |
| gene rearrangement, alpha-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the alpha-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, beta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the beta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, delta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the delta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, gamma-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the gamma-chain of antigen receptors. (12 Dec 1998) |
| M antigen | An antigen found in the cell of Streptococcus pyogenes; associated with virulence. See: beta-haemolytic streptococci. (05 Mar 2000) |
| receptor-CD3 complex, antigen, T-cell | Molecule composed of the non-covalent association of the T-cell antigen receptor (receptors, antigen, T-cell) with the CD3 complex (antigens, CD3). This association is required for the surface expression and function of both components. The molecule consists of up to seven chains: either the alpha/beta or gamma/delta chains of the T-cell receptor, and four or five chains in the CD3 complex. (12 Dec 1998) |
| receptors, antigen | Molecules on the surface of b- and T-lymphocytes that recognise and combine with specific antigens. (12 Dec 1998) |
