| 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. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

| 영문 | squamous cell carcinoma | 한글 | 편평세포암종 |
|---|---|---|---|
| 설명 | 편평세포 기원의 암으로서, 편평세포가 있는 어떤 곳에서든 발생가능함. 따라서 식도암, 피부암, 폐암, 자궁암 등이 여기에 해당된다. 특히 피부암은 많은 자외선조사에 의해 생기는 광선각화증에서 발생가능하다. 병리조직학적 특성으로서 각질을 생성한다. |

| antigen p150,95 | A major adhesion-associated heterodimer molecule expressed by human monocytes, granulocytes, nk cells, and some lymphocytes. The alpha subunit is the CD11c antigen (also called leu-m5), a surface antigen expressed on some myeloid cells. The beta subunit is the CD18 antigen (antigens, CD18). The p150,95 antigen has been shown to play an important role in cell-cell and cell-substrate adhesive interactions. (12 Dec 1998) |

| antigen presentation | A cell that carries on its surface antigen bound to MCH Class I or Class II molecules and presents the antigen in this context to T-cells. Includes macrophages, endothelium, dendritic cells and Langerhans cells of the skin. See: MHC restriction, histocompatibility antigens. (18 Nov 1997) |
| antigen-presenting cells | Immunocompetent cells, usually ia positive, that mediate the cellular immune response by processing and presenting antigens or mitogens which stimulate T-cell activation. (12 Dec 1998) |
| antigen processing | Modification of an antigen by accessory cells. This usually involves endocytosis of the antigen and either minimal cleavage or unfolding. The processed antigen is then presented in modified form by the accessory cell. (18 Nov 1997) |
| antigen shift | Abrupt change in antigens expressed by a species or variety of organisms. Usually seen in microorganisms where the change may allow escape from immune recognition. Antigenic drift is a more gradual change. See: antigenic variation. (18 Nov 1997) |
| antigen unit | The smallest amount of antigen that, in the presence of specific antiserum, will fix 1 complement unit. (05 Mar 2000) |
| aspergillus antigen skin test | <investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
| Au antigen | Auberger blood group |
| Aus antigen | <virology> An envelope antigen now known as HBsAg of Hepatitis B virus. Appearance of the antigen in serum is associated with a phase of high infectivity. (18 Nov 1997) |
| Australia antigen | <virology> An envelope antigen now known as HBsAg of Hepatitis B virus. Appearance of the antigen in serum is associated with a phase of high infectivity. (18 Nov 1997) |
| becker antigen | bea antigen |
| blood group antigen | <haematology, immunology> The set of cell surface antigens found chiefly, but not solely, on blood cells. More than fifteen different blood group systems are recognised in humans. There may be naturally occurring antibodies without immunisation, especially in the case of the ABO system and matching blood groups is important for safe transfusion. In most cases the antigenic determinant resides in the carbohydrate chains of membrane glycoproteins or glycolipids. See: Rhesus, Duffy, Kell, Lewis and MN. (25 Jun 1999) |
| cancer antigen 125 test | Test for cell-surface antigen found on derivatives of coelomic epithelium. Elevated levels of this antigen are associated with ovarian malignancy and benign pelvic disease such as endometriosis. (05 Mar 2000) |
| capsular antigen | That found only in the capsules of certain microorganisms; e.g., the specific polysaccharides of various types of pneumococci. (05 Mar 2000) |
| 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) |
