| 설명 | 방사성을 띠는 핵물질을 이용하여 의학에 응용하는 학문. 대개 인체에 큰 해가 없는 방사선물질을 사용하며, 반감기가 짧아 사용후에도 큰 해가 없다. 이런 핵의학적 물질을 이용한 핵의학적 진단의 가장 큰 장점은 생체내에서 일어나는 그 기관의 실제적인 기능을 알아볼 수 있다는 데 있다. 흔히 접하는 X-선을 이용한 진단방법은 단지 그 순간만의 영상을 접하여 실제로 보이는 부위가 얼마나 기능을 수행하는지 알 수 없는 단점이 있으나, 핵의학에서는 실제적인 기능의 정도에 따라 영상이 나오게 되므로 기능판별에 아주 유리하다. 하지만, 정확한 판별력이 있는 영상을 얻기에는 부족하다. 또한 핵의학은 진단외의 치료에도 사용되는데, 예를 들어 갑상샘종양의 경우 여러 곳에 이미 전이가 되어 있을 경우 방사선핵종을 이용하여 다른 곳에 큰 부작용없이 치료가 가능하다. |

| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25캜; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |

| cold agglutination test | <investigation> A test for blood antibodies which are present in certain peculiar types of pneumonia (atypical pneumonia, Mycoplasma) (27 Sep 1997) |
| cold agglutinin | An antibody which reacts more efficiently at temperatures below 37캜. (05 Mar 2000) |
| cold agglutinins | <haematology> Antibodies that agglutinate particles with greater activity below 32쵣. They are IgM antibodies specifically reactive with blood groups I and i in humans and agglutinate red blood cells on cooling, causing Raynaud's phenomenon in vivo. (18 Nov 1997) |
| cold allergy | Physical symptoms produced by hypersensitivity to cold. (05 Mar 2000) |
| cold antibody | See: cold agglutinin. (05 Mar 2000) |
| cold autoantibody | An autoantibody that reacts at temperatures below 37캽. (05 Mar 2000) |
| cold bend test | A test of the ability of a wire to be shaped; performed by counting the number of times a wire can be bent to a right angle and reversed at the same point before breaking; important in establishing specifications for orthodontic wires. (05 Mar 2000) |
| cold-blooded | <physiology> Having a varying body temperature. See Homoiothermal. Origin: Gr. Changeable + E. Thermal, thermic. Source: Websters Dictionary (01 Mar 1998) |
| cold-blooded animal | <biology, zoology> An organism, such as a fish or reptile, that is cold-blooded, i.e., one whose internal body temperature varies with that of the environment. (09 Oct 1997) |
| cold bone lesions | <radiology> Overlying atenuation caused by pacemaker, barium, metal cross, wristwatch, radiation therapy, local vascular compromise, early osteomyelitis, tumour: neuroblastoma, renal cell carcinoma, thyroid carcinoma, anaplastic tumours (e.g. Reticulum cell sarcoma) (12 Dec 1998) |
| cold cautery | The surgical destruction of tissue via the application of extreme cold, aswith liquid nitrogen. (09 Oct 1997) |
| cold chain | A system of protection against high environmental temperatures for heat-labile vaccines, sera and other biological preparations. (05 Mar 2000) |
| cold, common | A viral upper respiratory tract infection. A contagious illness caused by a number of different types of viruses. Because of the great number of viruses that can cause a cold, the body never builds up resistance (immune) against all of them. For this reason, colds are a frequent and recurring problem. In fact, preschool children average 9 colds a year; those in kindergarten, 12 colds a year; and adolescents and adults, 7 colds per year. Going out into the cold weather has no effect on the spread of a cold. Antibiotics do not help the common cold. (12 Dec 1998) |
| cold compress | <orthopaedics> This may be ice packs wrapped in cloth to deliver a cold compress to an acutely injured muscle, joint or bone. Cold compresses are commonly indicated for most injuries in the first 24-48 hours. They should be applied only intermittently, with periods of time without the compress applied. (27 Sep 1997) |
