| 설명 | 어떤 개체의 조직을 다른 개체에 이식했을 때 그것을 배제하는 생체반응. 개체간에 이식수술을 하면 처음 7~10일 정도는 혈액공급도 회복되고 별다른 이상을 발견하지 못하지만, 그 후에 괴사가 생긴다. 그 때문에 장기이식 후에 각종 증상이 발생하여 이식수술이 실패로 돌아가기 쉽다. 사람의 체내에 이종의 조직이 들어가면 그에 대해 항체가 만들어진다. 이는 혈액 속의 림프구가 그 이종조직에 접촉하여 활성화된 상태에서 림프절로 되돌아와서 거기서 항체를 만드는 것으로 생각되고 있다. 이 항체는 세포성항체와 체액성항체로 나누어지며 이 양자의 공동작용에 의해 거부반응이 생기는 것으로 보인다. 이는 개체방위반응이라고도 할 수 있지만 이식조직의 혈관은 그것들의 작용으로 내피세포가 상하여 혈전을 형성하므로 혈행이 두절된다. 그 때문에 괴사가 생기고 괴사조직은 체외로 배출된다. 거부반응은 이식직후에 생기는 것, 수주에서 수개월 후에 비교적 급성으로 생기는 것, 수년 후에 서서히 생기는 것이 있다. 장기 이식시에는 이 반응을 억제하기 위해 면역억제제나 부신겉질호르몬을 투여한다. |

| accelerated rejection | A transplant rejection manifested in less than three days. (05 Mar 2000) |
|---|---|
| acute cellular rejection | Graft rejection which usually begins within 10 days after a graft has been transplanted into a genetically dissimilar host. Lesions at the site of the graft characteristically are infiltrated with large numbers of lymphocytes and macrophages which cause tissue damage. See: primary rejection. Synonym: acute rejection. (05 Mar 2000) |
| acute kidney transplant rejection | <radiology> Findings on ultrasound: globular enlargment of the kidney, swelling and hypoechogenicity of the medullary pyramids, indistinct cortico-medullary junction, foci in the renal cortex (12 Dec 1998) |
| acute rejection | Graft rejection which usually begins within 10 days after a graft has been transplanted into a genetically dissimilar host. Lesions at the site of the graft characteristically are infiltrated with large numbers of lymphocytes and macrophages which cause tissue damage. See: primary rejection. Synonym: acute rejection. (05 Mar 2000) |
| allograft rejection | The rejection of tissue transplanted between two genetically different individuals of the same species. Rejection is caused by T lymphocytes responding to the foreign major histocompatibility complex of the graft. Synonym: homograft. (05 Mar 2000) |
| parental rejection | Withholding of affection from or denial of attention to one's child. Child's withholding of affection from its parent. (05 Mar 2000) |
| rejection | 1. <immunology, surgery> Usually used of grafts. Any process leading to the destruction or detachment of a graft or other specified structure. 2. <psychology> Non-acceptance, negative attitudes, hostility or excessive criticism of the individual which may precipitate feelings of rejection. (12 Dec 1998) |
| graft rejection | <haematology, immunology> When donated bone marrow infused during a bone marrow transplant is rejected by the patients body or does not take. (16 Dec 1997) |
| chronic allograft rejection | Immunologically mediated damage to the allograft, typically a kidney allograft, manifested by diffuse interstitial fibrosis glomerular changes, typically membranous and sclerotic in nature, as well as intimal fibrosis of the blood vessels with tubular atrophy and loss of tubular structures. (05 Mar 2000) |
| chronic rejection | A transplant rejection occurring after a few or many months, mainly from persisting serum antibody action. (05 Mar 2000) |
| primary rejection | A rejection occurring more than seven days after transplantation, mainly from a cellular immune response. (05 Mar 2000) |
| second set rejection | An accelerated rejection of a transplant that occurs when an individual has been previously sensitised to the graft. (05 Mar 2000) |
| hyperacute rejection | A rejection that usually develops in less than one hour from the implantation of a vascular graft, a form of antibody-mediated, usually irreversible damage to a transplanted organ, particularly the kidney, manifested predominantly by diffuse thrombotic lesions, usually confined to the organ itself and only rarely disseminated, for skin allograft rejection of this type, see white graft. (05 Mar 2000) |
| first-set rejection | Allograft transplantation between two organisms not previously sensitised to the graft tissue. Necrosis of the graft usually occurs within 10 days of transplantation. (05 Mar 2000) |
| aetiological fraction | <epidemiology> The reduction in disease when a risk factor is removed. If I* is the number of people that a risk factor is responsible for and I is the total number of cases over the same period, then the aetiological fraction is I*/I. Equivalently, the aetiological fraction is (I-Io)/I. Where Io is the number of cases in the absence of the risk factor. Also known as the attributable fraction. (05 Dec 1998) |
