| 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. |

| paracervical block anaesthesia | Regional anaesthesia of the cervix uteri by injection of local anaesthetic solution into tissues adjacent to the cervix. (05 Mar 2000) |
|---|---|
| genetic block | <biochemistry, molecular biology> An obstruction in a biochemical pathway caused by a mutation that has crippled production of an enzyme critical to the pathway. (07 May 1998) |
| partial heart block | Impulses penetrate the atrioventricular junction in some relation to the ventricular rate. Synonym: incomplete atrioventricular block. (05 Mar 2000) |
| retrograde block | Impaired conduction backward from the ventricles or A-V node into the atria. (05 Mar 2000) |
| peri-infarction block | An electrocardiographic abnormality associated with an old myocardial infarct and caused by delayed activation of the myocardium in the region of the infarct; characterised by an initial vector directed away from the infarcted region with the terminal vector directed toward it. (05 Mar 2000) |
| phase I block | Inhibition of nerve impulse transmission across the myoneural junction associated with depolarisation of the motor endplate, as in the muscle paralysis produced by succinylcholine. (05 Mar 2000) |
| phase II block | Inhibition of nerve impulse transmission across the myoneural junction unaccompanied by depolarisation of the motor endplate, as in the muscle paralysis produced by tubocurarine. (05 Mar 2000) |
| Mobitz block | Second degree atrioventricular block in which there is a ratio of two or more atrial deflections (P waves) to ventricular responses. Mobitz types of atrioventricular block, type I, the dropped beat of the Wenckebach phenomenon; type II, a dropped cardiac cycle that occurs without alteration in the conduction of the preceding intervals. (05 Mar 2000) |
| Wenckebach block | A form of block in any cardiac tissue (most often the atrioventricular junction) in which there is progressive lengthening of conduction until the beat is dropped. (05 Mar 2000) |
| complete A-V block | complete atrioventricular dissociation, complete A-V dissociation |
| Wilson block | The commonest form of right bundle-branch block, characterised in lead I by a tall slender R wave followed by a wider S wave of lower voltage. (05 Mar 2000) |
| Wolff-Chaikoff block | Blocking of the organic binding of iodine and its incorporation into hormone caused by large doses of iodine; usually a transient effect, but in large doses in susceptible individuals it can be prolonged and cause iodine myxoedema. Synonym: Wolff-Chaikoff effect. (05 Mar 2000) |
| conduction block | Failure of impulse transmission at some point along a nerve, although conduction along the segments proximal and distal to it are unaffected. Clinically, most often caused by an area of focal demyelination; when caused by focal trauma, called neurapraxia. (05 Mar 2000) |
| congenital heart block | Atrioventricular block present in utero or at birth and usually of advanced or complete degree. (05 Mar 2000) |
| hanging-block culture | The propagation of microorganisms on a cube of solidified agar medium which is inoculated, attached to a cover glass, and inverted over a moist chamber or hollowed slide. (05 Mar 2000) |
