| 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 insoluble globulin | <haematology> Name, now obsolete, originally given to fibronectin prepared from cryoprecipitate. (18 Nov 1997) |
|---|---|
| cold in the head | An acute catarrhal inflammation of the mucous membrane of the nose, marked by sneezing, lacrimation, and a profuse secretion of watery mucus; usually associated with infection by one of the common cold viruses. Synonym: cold in the head, coryza. (05 Mar 2000) |
| cold light | Fluorescent light as opposed to incandescent light. (05 Mar 2000) |
| cold liver lesion | <radiology> Size for detection = 1-2 cm (3-cm deep lesions), primary tumour (haemangioma hot by Tc-RBCs), metastasis, inflammatory lesion (e.g., amebic abscess), degenerative disease, trauma, congenital lesion (solitary cyst or polycystic disease) see: liver-spleen scan (12 Dec 1998) |
| cold nodule | A thyroid nodule with a much lower uptake of radioactive iodine than the surrounding parenchyma; about one in four prove to be malignant. (05 Mar 2000) |
| cold pack | A pack of cloth or other material soaked in cold water or encasing ice. (05 Mar 2000) |
| cold pressed | <technique> A more natural process by which vegetable oils are produced to yield greater nutrient value. Cold pressing does not use heat or chemicals that commercial pressing does. (27 Sep 1997) |
| cold pressor test | A cardiocirculatory challenge conventionally performed by immersing one hand in ice cold water for two or more minutes (as tolerated) to acutely raise the blood pressure, thus imposing resistance to ejection of blood from the left ventricle into the systemic arterial system and consequently acutely increased afterload (afterload = increased left ventricular wall stress). Synonym: Hines-Brown test. (05 Mar 2000) |
| cold processed | <technique> A process by which chemicals are used to extract vegetable oils. The chemicals are later filtered out. (27 Sep 1997) |
| cold-reactive antibody | See: cold agglutinin. (05 Mar 2000) |
| cold-rigor point | The degree of lowered temperature at which the activity of a cell ceases and the cell passes into the narcotic or hibernating state. (05 Mar 2000) |
| cold sensitive enzyme | <enzyme> An enzyme that loses its stability as the temperature is lowered. (05 Mar 2000) |
| cold-sensitive mutant | A mutant that is defective at low temperature but functional at normal temperature. Compare: temperature-sensitive mutant. (05 Mar 2000) |
| cold sore | <dermatology, virology> An infection of the lips or mouth which results in a blistery sore that is caused by Herpes simplex type 1. Painful blisters (eventually becoming ulcers) will often presenting on the lips or nasal mucosa. Infected individuals should avoid contact with others due to potential for transfer of the infection. Herpes labialis tends to be recurrent and often exacerbated by stress, sunlight, fever or illness. Treatment includes the use of antiviral creams (acyclovir) and oral medications (acyclovir). Pre-treatment with oral acyclovir, in those prone to cold sores (prior to sun exposure, etc.) has been shown to decrease exacerbations. (27 Sep 1997) |
| cold spleen lesion | <radiology> Infarction, lymphoma, haematoma, tumour, splenic artery aneurysm, pancreatic pseudocyst, variant, artifact, absent spleen, splenectomy, sickle cell disease, trauma see: liver-spleen scan (12 Dec 1998) |
