|---|---|---|---|
| 설명 | 면역이란 자신의 것과 자신의 것이 아닌 것을 구분해서 자신의 것이 아닌 것을 공격하여 생물학적 활성을 없애거나 제거하는 것이다. 이 면역은 주로 혈액에 있는 세포에 의해서 이루어진다. 특히 림프구는 이 면역에 중추적인 역할을 하는 세포이다. 이식편대숙주반응이라는 것은 이식되어온 조직에 존재하는 타인의 혈구들이 숙주의 세포를 공격하는 것을 말한다. 즉 이식되어온 조직과 함께 들어온 혈구들이 이식을 받은 사람의 세포를 타인의 것으로 인지해서 공격하는 현상이다. 이것은 이식을 받은 사람의 면역상태가 정상적일 경우에는 일어나지 않는데 왜냐하면 면역상태가 정상일 경우에는 이식되어온 장기와 더불어 들어온 타인의 혈구들을 이식을 받은 사람의 혈구가 타인의 것으로 인지해서 공격을 하고 숫적으로 유리하여 모두 죽일 수가 있기 때문이다. |

| immune agglutination | Agglutination caused by antibody (agglutinin) that is specific for the suspended microorganism, cell, or for an antigen that has been coated on a particle of suitable size. (05 Mar 2000) |
|---|---|
| indirect agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| false agglutination | 1. Agglomeration of particles in solution which does not involve antigen-antibody combination. Synonym: false agglutination. Synonym: rouleaux formation. (05 Mar 2000) |
| latex agglutination | Also known as latex particle agglutination, for detection of antibodies is identical to haemagglutination in principle, but the substitution of smaller, antigen-coated latex particles for erythrocytes results in improved sensitivity and reagent longevity. Alternatively, antibodies can be absorbed to the latex particles (under appropriate ionic and pH conditions) by binding to the Fc region of antibodies, leaving the Fab region free to interact with antigens present in the applied specimens. This phenomenon has made latex agglutination a popular technique for detecting antigens as well. (05 Mar 2000) |
| latex agglutination test | A passive agglutination test in which antigen is adsorbed onto latex particles which then clump in the presence of antibody specific for the adsorbed antigen. Synonym: latex fixation test. (05 Mar 2000) |
| malignant mixed mullerian tumour | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. Synonym: malignant mixed mullerian tumour. (05 Mar 2000) |
| gonadal dysgenesis, mixed | A syndrome of gonadal dysgenesis in which there is a testis on one side and a "streak gonad" on the other. The phenotype is generally male, but may be female since the individual is a mosaic. Various karyotypes have been identified, including 45,xo/47,xyy; 45,xo/46,xy; and 45,xo/46,xyo. (12 Dec 1998) |
| mixed | Formed by mixing; united; mingled; blended. See Mix, Mixed action, voices of both males and females united in the same performance. Source: Websters Dictionary (01 Mar 1998) |
| mixed aphasia | In which all aspects of speech and communication are severely impaired. at best, patients can understand or speak only a few words or phrases; they cannot read or write. Synonym: mixed aphasia, total aphasia. (05 Mar 2000) |
| mixed astigmatism | Astigmatism in which one meridian is hyperopic while the one at right angle to it is myopic. (05 Mar 2000) |
| mixed beat | A beat triggered by more than a single electrical impulse, when the wave fronts coincide to act together on a single final pathway of activity; in the electrocardiogram, the atrial or ventricular complex when either atria or ventricles are activated jointly by two simultaneous or nearly simultaneous invading impulses. Synonym: combination beat, mixed beat, summation beat. (05 Mar 2000) |
| mixed cell leukaemia | Term infrequently used as a designation for granulocytic leukaemia, thereby emphasizing the occurrence of different types of cells in the myeloid series (i.e., neutrophilic, eosinophilic, and basophilic granulocytes), in contrast to the comparatively monotonous pattern observed in lymphocytic and monocytic leukaemia. (05 Mar 2000) |
| mixed chancre | A sore resulting from simultaneous inoculation of a site with syphilis and chancroid. (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) |
| mixed dentition | <dentistry> The situation when both deciduous and permanent teeth are present. (08 Jan 1998) |
