| 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. |

| contrast bath | A bath in which a part is immersed in hot water for a period of a few minutes and then in cold, the hot and cold periods alternated regularly at intervals, usually half-hours; used to increase the blood flow to the part. (05 Mar 2000) |
|---|---|
| contrast echocardiography | The injection of contrast media of high echo reflectants (e.g., bubbles) to outline a chamber or delineate a shunt within the heart. (05 Mar 2000) |
| contrast enema | Enema using barium or another contrast medium. (05 Mar 2000) |
| contrast enhancement | The intravenous administration of water-soluble iodinated contrast material, which increases the CT number of the vascular pool, as well as some lesions (particularly in the brain), due to abnormal leakage into the interstitium; the property of showing increased radiopacity from concentration of contrast medium. (05 Mar 2000) |
| contrast material | A substance that is introduced into or around a structure and, because of the difference in absorption of X-rays by the contrast medium and the surrounding tissues, allows radiographic visualisation of the structure. (18 Nov 1997) |
| contrast media | <radiology> Side-effects from high osmolality / viscosity (fluid shifts from different compartments), vasodilatation, heat, pain, osmotic diuresis, haemodynamic changes, pharmacokinetics, distribute volume into extracellular space, clearance by glomerular filtration and renal excretion, physiologic reaction, increased plasma osmolality causes fluid shift from RBCs and pulmonary tissue leading to increased plasma volume, then osmolar gradient reverses with passage of contrast bolus to pulmonary capillary endothelium leaks protein into pulmonary interstitium leading to increased pulmonary oedema, transient cardiovascular changes (magnitude increased with tonicity of medium), increased PAP, increased CO with decreased peripheral/pulmonary vascular resistance, decreased systemic arterial pressure (variable), may activate gen receptors causing side effects (12 Dec 1998) |
| contrast medium | A substance that is introduced into or around a structure and, because of the difference in absorption of X-rays by the contrast medium and the surrounding tissues, allows radiographic visualisation of the structure. (18 Nov 1997) |
| contrast sensitivity | The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease. (12 Dec 1998) |
| contrast stain | <technique> A dye used to colour one portion of a tissue or cell which remained unaffected when the other part was stained by a dye of different colour. Synonym: differential stain. (05 Mar 2000) |
| contrast transfer function | <microscopy> A mathematical function that expresses the ability of an optical or electronic device to transfer signals faithfully as a function of the spatial or temporal frequency of the signal. The modulation transfer function is the ratio of percentage modulation of a sinusoidal signal leaving to that entering the device over the range of frequencies of interest. The modulation transfer function is usually presented as a graph of modulation transfer function versus log (frequency). For a square wave signal, the function is known as the CTF. Acronym: MTF (26 Mar 1998) |
| high osmolar contrast agent | Ionic water-soluble iodinated contrast media. Synonym: high osmolar contrast medium. (05 Mar 2000) |
| high osmolar contrast medium | Ionic water-soluble iodinated contrast media. Synonym: high osmolar contrast medium. (05 Mar 2000) |
| simultaneous contrast | The enhancement of the visual sensation of white when a white object is viewed adjacent to a black object; the black object also appears blacker as a result of the contiguity of white. Adjacent complementary colours also appear brighter; e.g., green appears a brighter green and red a brighter red if these two colours are viewed side by side. (05 Mar 2000) |
| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |
| successive contrast | The visual effect caused by viewing a brightly coloured object and then a gray surface; the latter appears tinged with the complementary colour of the object. Viewing a surface coloured in the complementary colour of the object rather than in gray enhances the colour intensity of the surface. (05 Mar 2000) |
