| 설명 | 기체물질을 통틀어 이르는 말. 본래 물질의 3형태 중 하나인 기체를 지칭하나, 일반적으로는 화산이나 온천에서 분출하는 가스, 산이나 해상에서 발생하는 안개, 신체의 소화기 내에서 발효하는 가스 등도 가스라고 말한다. 가스괴저: gas gangrene 흙이나 장관내에 정상적으로 서식하는 Clostridium이라는 균의 감염에 의해서 생기는 괴저를 말한다. Clostridium중에서도 특히 C. perfringens에 의한 감염이 가장 중요하다. 이 균에 의한 감염은 우선 근육을 침범하여 근염의 형태로 나타나며 주로 조직의 결손에 의해서 그곳으로 흙이나 다른 이물질과 함께 이 균이 체내에 들어가 병터가 시작된다. 잠복기간은 2일 정도로 초기증상은 동통, 가슴 두근거림, 저혈압 등이 발생한다. 이 균은 심하게 조직을 파괴하고 또한 대사과정 중에서 정상적으로 가스를 발생하므로 감염된 병변의 파괴와 더불어서 가스가 차므로 마치 공기주머니 같은 병터을 만든다. 초기 병터는 백색으로 반짝이며 팽팽한 감을 주고 시간이 지나면 변색이 되면서 물집이 발생하며 말기에는 상처의 변두리부위의 조직이 죽어가기 시작한다. 병터에는 가스가 차므로 상처의 주변을 누르면 "뿌드득"하는 듯한 소리를 들을 수가 있는데 이것이 중요한 진단의 단서가 될 수가 있지만 없는 경우도 있다. 치료는 신속히 외과적으로 병터를 절개하고 시행하며 항생제를 정맥으로 다량 주입한다. |

| natural antibody | Antibody demonstrable in the serum or plasma of various persons or animals not known to have been stimulated by specific antigen, either artificially or as the result of naturally occurring contact. Synonym: natural antibody. (05 Mar 2000) |

| natural haemolysin | Haemolysin occurring in the plasma of an animal of one species, e.g., a dog, which fixes complement with the red blood cells of some other species, e.g., a rabbit, thereby causing haemolysis of the cells of the rabbit, although the dog was not previously exposed to antigenic stimulation with such cells.

| natural history | A former branch of knowledge embracing the study, description, and classification of natural objects (as animals, plants, and minerals) and thus including the modern sciences of zoology, botany, and mineralogy insofar as they existed at that time. In the 17th, 18th, and 19th centuries it was much used for the generalised pursuit of certain areas of science. (webster, 3d ed; from dr. James h. Cassedy, nlm history of medicine division) (12 Dec 1998) |
| natural immunity | This includes local barriers to infection such as skin, stomach acid, mucous, the cough reflex, enzymes in tears and saliva and skin oils. (27 Sep 1997) |
| natural killer cell | <haematology, immunology> A certain type of white blood cell that attacks tumour cells and infected body cells by binding to a tumour cell and releasing lethal chemicals. Natural killer cells are thought to play a key role in cancer prevention by killing abnormal cells before they multiply and grow. (16 Dec 1997) |
| natural killer cells | Large granular lymphocytes which do not express markers of either T or B-cell lineage. These cells do possess Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. NK cells can also use perforin to kill cells in the absence of antibody. Killing may occur without previous sensitization. Synonym: NK cells. (05 Mar 2000) |
| natural killer cell stimulating factor | <cytokine> A 75 kD heterodimeric cytokine composed of disulfide-bonded 40 kD and 35 kD subunits that was originally identified by its ability to induce cytotoxic effector cells in synergy with less than optimal concentrations of interleukin-2. It is released by macrophages in response to infection and promotes the activation of cell-mediated immunity. Specifically, IL-12 triggers the maturation of Thl CD4 cells, specific cytotoxic T-lymphocyte responses and an increase in the activity of NK cells and consequently, it is the initiator of cell-mediated immunity. It enhances the lytic activity of NK cells, induces interferon production, stimulates the proliferation of activated T-cells and NK cells. Is secreted by human B lymphoblastoid cells (NC 37). May play a role in controlling immunoglobulin isotype selection as it also inhibits IgE synthesis (even in the presence of anti-IFN monoclonal antibody) and as a growth factor for activated CD4+ and CD8+ T-cells independently of interleukin-2, and for CD56+ NK cells but not resting peripheral blood mononuclear cells or resting or activated tonsillar B-cells. It is likely that interleukin 12 has a major role in protective immunity against viruses and is under study as an immunotherapy in HIV infection. Formerly referred to as cytotoxic lymphocyte maturation factor. Acronym: IL-12 (12 Dec 1998) |
