| 영문 | complement fixation reaction | 한글 | 보체결합 반응, 도움체결합반응 |
|---|---|---|---|
| 설명 | 항체와의 반응에 있어서 보체와 결합하는 항체를 검사하는 방법으로, 이 반응은 최초에 기지항원, 피검혈청 및 보체를 혼합한다. 제2단계에서는 적혈구와 이것에 대응하는 용혈소의 혼합액을 가한다. 본 반응후 용혈이 일어나지 않으면 본체는 항원항체결합물에 결합한 것이 되어 양성이 되지만, 용혈이 일어난 경우 보체는 결합하지 않아 소비되지 않기 때문에 음성이 된다. 본 반응은 기지혈청을 써서 항원검출에 응용할 수 있으며, 마이코플라스마, 리케챠, 클라미디아, 바이러스, 매독 등의 진단에 쓰인다. |

|---|---|---|---|
| 설명 | 수혈하였을 때에 환자에게 일어나는 반응. 알레르기 반응과 용혈 반응이 있다. |

| 영문 | graft versus host reaction | 한글 | 이식편대 숙주반응 |
|---|---|---|---|
| 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. |

| stress echocardiogram | <investigation> An echocardiogram that is performed after a period of physical exertion. Chemical stimulation of the heart (to mimic exertion) is used in some cases where physical activity is not possible. In some cases, exertion may manifest a cardiac abnormality not obvious during echocardiography in the resting heart. (27 Sep 1997) |

| stress echocardiography | Echocardiographic monitoring of a circulatory challenge, usually exercise. Transesophageal echocardiography, recording of the echocardiogram from a transducer swallowed by the patient to predetermined distances in the oesophagus and stomach. Transthoracic echocardiography, the standard echocardiography recorded from echocardiographic "windows" on the precordium. Two-dimensional echocardiography, echocardiography in which an image is reconstructed from the echoes stimulated and detected by a linear array or moving transducers. Synonym: B-mode echocardiography, cross-sectional echocardiography. (05 Mar 2000) |
| stress fibre | <physiology> Long bundles of microfilaments made up of actin subunits. They are involved in the attachment of cultured cells to a substratum, the determination of cell shape and may be involved in cellular mobility. They are found in most cells and have been shown to be contractile, have a periodicity reminiscent of the sarcomere and are anchored at one end to a focal adhesion, although sometimes between two focal adhesions. (17 Jul 2002) |
| stress fracture | <orthopaedics, radiology> A hairline or microscopic break in the bone that is not demonstrable with conventional X-rays. Symptoms include a dull aching pain with tenderness at the site. Symptoms often increase with activity and diminish with rest. Nuclear bone scanning will reliably demonstrate stress fractures where conventional radiographs often fail. Although they may occur in most any location, they are most common in the tibia, fibula and metatarsal bones. (27 Sep 1997) |
| stress immunity | Insusceptibility or resistance to the effects of emotional strain. (05 Mar 2000) |
| stress induced protein | <molecular biology> Alternative and preferable name for heat-shock proteins of eukaryotic cells, which emphasises that the same small group of proteins is stimulated both by heat and various other stresses. (18 Nov 1997) |
| stress, mechanical | A purely physical condition which exists within any material because of strain or deformation by external forces or by non-uniform thermal expansion; expressed quantitatively in units of force per unit area. (12 Dec 1998) |
| stress, psychological | Stress wherein emotional factors predominate. (12 Dec 1998) |
| stress riser | A mechanical defect, such as a hole, in bone or other materials that concentrates stress in the area. (05 Mar 2000) |
| stress shielding | Osteopenia occurring in bone as the result of removal of normal stress from the bone by an implant. (05 Mar 2000) |
| stress-strain curve | A curve showing the ratio of deformation to load during the testing of a material in tension. (05 Mar 2000) |
| stress test | Any cardiac challenge, physical, pharmacologic, or mental delivered under monitored conditions. Most commonly this is exercise, the most common monitor being electrocardiography although any other graphic technique, including cardiac catheterization, may be applied. (05 Mar 2000) |
| stress ulcers | An ulcer of the duodenum in a patient with extensive superficial burns, intracranial lesions, or severe bodily injury. Synonym: stress ulcers. (05 Mar 2000) |
| stress urinary incontinence | Leakage of urine as a result of coughing, straining, or some sudden voluntary movement, due to weakness of the fascia muscles and at the neck of the bladder. Synonym: urinary exertional incontinence. (05 Mar 2000) |
| dental stress analysis | The description and measurement of the various factors that produce physical stress upon dental restorations, prostheses, or appliances, materials associated with them, or the natural oral structures. (12 Dec 1998) |
