| 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 cream | A water-in-oil emulsion of various oils, waxes, and water; the standard formula, rose water ointment, contains expressed almond oil, rose water, spermaceti, white paraffin wax, and sodium borate; used as a cleansing or lubricating cream. (05 Mar 2000) |

| cold cure resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |
| cold erythema | Rash characterised by redness and itching, brought on by exposure to cold. (05 Mar 2000) |
| cold gangrene | A form of gangrene in which the involved part is dry and shriveled. Synonym: cold gangrene, mummification necrosis, mummification. (05 Mar 2000) |
| cold haemagglutinin disease | A condition associated with the presence of haemagglutinating autoantibody active in vivo but in vitro particularly or solely active in the cold; when the concentration of IgM antibody is high there may be increased serum viscosity, but clinical manifestations (due to haemagglutination) usually appear following exposure to cold; haemolysis usually is mild but may be severe, resulting in autoimmune haemolytic anaemia, cold antibody type. (05 Mar 2000) |
| cold haemolysin | An autoantibody of the IgG class responsible for paroxysmal cold haemoglobinuria; it is adsorbed to red cells only at temperatures of 20캜 or lower, causing the red cells to lyse in the presence of complement at higher temperatures; it has only slight agglutinating properties in spite of its marked lytic activity, and has a specificity within the blood group P; it is also occasionally present for short periods of time following measles and other infections, and formerly was frequently associated with syphilis. Synonym: cold haemolysin. (05 Mar 2000) |
| cold injury | Cold injuries include chilblains, trench foot, and frostbite. Cold injuries occur with and without freezing of body tissues. The young and the elderly are especially prone to cold injury. Alcohol increases the risk of cold injury which can lead to loss of body parts and even to death. It is important not to thaw an extremity if there is a risk of it re-freezing. (12 Dec 1998) |
| 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) |
