| 영문 | granulation tissue | 한글 | 육아조직 |
|---|---|---|---|
| 설명 | 모세혈관이 풍부하며 왕성하게 증식을 계속하는 어린 결합조직. 창상 등 조직 결손에 대한 수복, 이물처리의 기질화, 염증이 만성적인 경과에 있거나 종양증식에 동반된 사이물질의 반응성 염증에서 관찰된다. 구성성분은 생긴지 얼마 안되는 어린 육아조직은 섬유모세포의 증식, 새로 생긴 모세혈관과 여러 유주세포 및 다른 중간엽세포(백혈구, 림프구, 형질세포, 조직구, 단핵구, 거대세포)등으로 구성된다. 이것이 시간이 지나 그리되면, 모세혈관과 유주세로, 다른조직성분을 감소시켜 만성화하여 오래된 육아가 되며 결국은 섬유세포와 아교질섬유로 구성된 반흔조직으로 변한다. |

| 영문 | tissue | 한글 | 조직 |
|---|---|---|---|
| 설명 | 특정 구조와 기능을 갖는 세포 집단. 세포 사이에는 다소간 세포간질이 들어 있다. 세포간질에는 글리코사미노글리칸, 히드록시아파타이트와 같은 기질과 아교질섬유와 같은 섬유가 발견된다. 조직성상은 구성세포와 세포간질의 종류와 양에 의해 결정된다. 조직은 상피조직, 지지조직, 근육조직, 신경조직으로 대별되며, 상피조직은 세포간질을 거의 갖지 않으며, 지지조직은 결합조직이나 뼈조직과 같이 세포간질이 풍부한 것이 많다. |

| 영문 | tissue biopsy | 한글 | 조직생검 |
|---|---|---|---|
| 설명 | 환자의 병적인 조직의 일부를 떼어 내서 병리조직표본을 만들어서 현미경적으로 검사하는 것. 외과적 수술재료로부터 병리조직학적 검사를 하여 생체내의 병변을 추구하는 분야를 외과병리학이라고 한다. 생검에는 쐐기생검, 천자침생검, 꿰뚫기식생검, 내시경생검 외에 세포진이라고 불리우는 박리세포진이나 세척세포진 등 떨어진 세포를 도말검사하는 방법이 포함된다. |

| 영문 | target tissue | 한글 | 표적조직 |
|---|---|---|---|
| 설명 | 호르몬에 대하여 표적이 되는 세포라는 의미로서 그 호르몬에 대한 수용체를 가지고 있는 세포. 예를 들어 인슐린은 인슐린 수용체를 가진 세포를 표적세포로 하여 이 세포에만 작용한다. |

| 영문 | subcutaneous tissue, subcutis | 한글 | 피하조직 |
|---|---|---|---|
| 설명 | 피부에서 진피의 아랫부분을 말함. 여기에는 지방조직이 많다. 기능은 열의 격리, 충격흡수, 영양저장소 등이다. |

| reticular tissue | Retiform tissue, a tissue in which the argyrophilic collagenous fibres form a network and that usually has a network of reticular cells associated with the fibres. (05 Mar 2000) |
|---|---|
| periapical tissue | Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone. (12 Dec 1998) |
| granulation tissue | Highly vascularised tissue that replaces the initial fibrin clot in a wound. Vascularisation is by ingrowth of capillary endothelium from the surrounding vasculature. The tissue is also rich in fibroblasts (that will eventually produce the fibrous tissue) and leucocytes. (18 Nov 1997) |
| granule cell of connective tissue | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |
| mesenchymal tissue | Embryonic connective tissue. See: mesenchyme. (05 Mar 2000) |
| peripheral lymphoid tissue | Secondary lymphoid tissue, not necessarily located peripherally. See: lymphoid tissue. (18 Nov 1997) |
| mesonephric tissue | Intermediate mesoderm situated in the thoracic and lumbar regions of the embryo or foetus; it evolves into the mesonephros and associated structures. (05 Mar 2000) |
| metanephrogenic tissue | Tissue derived from the intermediate mesoderm caudal to mesonephric levels and concerned with the formation of the nephrons of the metanephros. (05 Mar 2000) |
| ground tissue | <plant biology> Plant tissues other than those of the vascular system and the dermal tissues. Composed of relatively undifferentiated cells. (18 Nov 1997) |
| guided tissue regeneration | The repopulating of the periodontium, after treatment for periodontal disease. Repopulation is achieved by guiding the periodontal ligament progenitor cells to reproduce in the desired location by blocking contact of epithelial and gingival connective tissues with the root during healing. This blocking is accomplished by using synthetic membranes or collagen membranes. (12 Dec 1998) |
| chondroid tissue | In an adult, tissue resembling cartilage. In an embryo, an early stage in cartilage formation. Synonym: fibrohyaline tissue, pseudocartilage. (05 Mar 2000) |
| gut-associated lymphoid tissue | <physiology> Peripheral lymphoid organ consisting of lymphoid tissue associated with the gut (Peyer's patches, tonsils, mesenteric lymph nodes and the appendix). It is especially rich in B-cells and is responsible for localised immunity to pathogens such as bacteria, viruses, and parasites. (20 Sep 2002) |
| chromaffin tissue | Tissue in medulla of adrenal gland containing two populations of cells, one producing adrenaline, the other noradrenaline. The catecholamine is associated with carrier proteins (chromogranins) in membrane vesicles (chromaffin granules). (18 Nov 1997) |
| rubber tissue | A thin sheet of rubber used as a cover in surgical dressings. (05 Mar 2000) |
| mixed connective tissue disease | <syndrome> A syndrome with overlapping clinical features of systemic lupus erythematosus, scleroderma, polymyositis, and Raynaud's phenomenon. The disease is differentially characterised by high serum titres of antibodies to ribonuclease-sensitive extractable (saline soluble) nuclear antigen (nuclear ribonucleoprotein) and a speckled epidermal nuclear staining pattern on direct immunofluorescence. A more modern term for this condition is the undifferentiated connective tissues disease. (22 Sep 2002) |
