| 영문 | necrosis | 한글 | 괴사 |
|---|---|---|---|
| 설명 | 세포가 죽는 것을 말한다. 원인은 어떤 외상일 수도 있고, 혹은 동맥이 좁아져서 피가 통하지 않아 죽게 되는 것일 수도 있다. 어떤 경우이든, 괴사된 조직이 체내에 있으면, 결국은 여러 합병증을 불러 일으키므로 제거되어야 한다. 괴저괴사: gangrenous necrosis 괴저괴사라는 용어는 보통 괴사라는 것과 크게 다른 것은 없으나 임상, 특히 외과에서 흔히 쓰고 있는 말이다. 이는 팔다리, 특히 다리에서 많이 생기는데 혈액공급이 소실되고 그 후에 세균감염을 받아서 생기는 병터이다. 만약 혈류공급의 차단에 의한 조직의 죽음이 주병변이고 이차적 세균의 감염이 적고, 있더라도 아주 미약해서 병터가 마르고 액체성분이 적을 경우에 이것을 건성괴저(dry gangrene)이라고 하고, 세균의 감염이 아주 많아서 죽은 조직이 분해가 되어서 액체성분이 괴저의 조직에 많이 있어서 보기에 습해 보이면 이것을 습성괴저(wet gangrene)이라고 한다. |

| 영문 | fibrinoid necrosis | 한글 | 섬유소성괴사 |
|---|---|---|---|
| 설명 | 초기의 류마티스 혹은 악성종양 등에서 볼 수 있는 혈관-결합조직의 특유한 변화로 혈관벽이나 주위의 결합조직이 섬유소모양으로 균질한 물질로 되고, 호산성으로 염색된다. 이것은 섬유소와 거의 똑같은 염색성을 나타내기 때문에 염증에서 혈관으로부터 섬유소 또는 섬유소모양의 물질이 삼출하여 결합조직 섬유간에 침착하여 구조가 불명료한 것으로 생각되었으나, 최근 조직화학, 전자현미경 등에 의하여 결합섬유자체에도 변화가 있는 것으로 면역글로불린의 침착도 증명되고 있다. |

| 영문 | coagulation necrosis | 한글 | 응고괴사 |
|---|---|---|---|
| 설명 | 세포의 죽음을 나타내는 형태학적 변화로서 괴사부위가 응고한 상태로 있는 것. 괴사세포는 호산성 덩어리로 보이며 적어도 수일간 세포의 기본 윤곽이 보존되기 때문에 조직구조를 식별할 수 있다. 대표적으로 허혈괴사를 들 수 있다. 경색과 허혈에 의한 저산소증시 심장근이나 콩팥에서 관찰되거나 전기 및 수은중독시 콩팥의 요세관에서 관찰되는 것으로 단백의 변성 후 남아있기 때문이다. 세포의 윤곽이 남아 있어 원래 조직의 구조를 형태학적으로 인식할 수 있는 것이 특징이다. |

| 영문 | caseation necrosis | 한글 | 치즈괴사, 건락괴사 |
|---|---|---|---|
| 설명 | 조직이 치즈와 같이 건조하고, 형태가 없는 덩어리로 변화하는 것으로 결핵감염 병터에서 볼 수 있는 독특한 괴사의 하나이다. |

| progressive emphysematous necrosis | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
|---|
| emphysematous | <medicine> Pertaining to, or of the nature of, emphysema; swelled; bloated. Origin: Cf. F. Emphysemateux. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| emphysematous cholecystitis | <radiology> Ring of air in RUQ, Differential diagnosis: pneumatosis coli, lipomatosis of gall bladder (rare!), follow plain X-ray with ultrasound, males (3:1), especially diabetics, usually acalculous, high mortality (12 Dec 1998) |
| emphysematous cystitis | Inflammation of the bladder wall caused by gas-forming bacteria, usually secondary to diabetes mellitus. (05 Mar 2000) |
| emphysematous gangrene | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| emphysematous gastritis | <radiology> Rare but severe form of widespread phlegmonous gastritis secondary to, mucosal disruption, ingestion of toxic/corrosive substances (most common), alcohol abuse, trauma, gastric infarction, necrotizing enterocolitis, ulcer X-ray: linear small gas bubbles within grossly thickened wall, may be associated with gas in the portal vein prognosis: leads to cicatrical stenosis, 60-80% mortality (12 Dec 1998) |

| acute tubular necrosis | <nephrology> A kidney disorder that results in damage to the renal tubule cells leading to acute renal failure. Acute tubular necrosis can result from any condition which deprives the kidney of oxygen (ischaemia). Acute tubular necrosis may occur as a complication of shock, trauma or sepsis. Conditions such as diabetes or liver disease can predispose people to the development of acute tubular necrosis. Certain medications (for example aminoglycosides, amphotericin B, cyclosporine) are known to cause acute tubular necrosis as a toxic side effect. Radiopaque contrast dyes, used in some radiologic procedures, may also result in acute tubular necrosis as a rare complication from contrast dye use. Acronym: ATN (13 Nov 1997) |
| aseptic necrosis | <orthopaedics, pathology> Condition in which poor blood supply to an area of bone leads to bone death. Also called avascular necrosis and osteonecrosis. (12 Dec 1998) |

| receptors, tumour necrosis factor | Cell surface receptors that bind tumour necrosis factor and trigger changes which influence the behaviour of cells.
