| 설명 | 치아의 조직이 세균에 의해 용해내지 파괴되어 점차 통증을 나타내다가 치아를 잃게 되는 하나의 세균성 병이라고 볼 수 있다. 우리나라에서는 영구치의 충치 이환율이 약 80%로, 한 사람이 2~3개의 충치를 갖고 있는 셈이며, 구강 보건상태는 도시, 농촌지역, 해안지역 순으로 좋다. 원인은 치태(dental plaque)로서, 이것은 점액이나 탈락한 잇몸의 세포들, 그리고 세균 등으로 이루어져 있으며, 점착성이 강하여 치아 표면에 잘 부착되어 양치질이나 칫솔질로는 쉽게 제거되지 않는다. 치태에는 그물모양의 구조내에 막대균과 알균이 섞여 있는데, 특히 내산성 사슬알균과 젖산균이 많다. 현재 가장 유력한 충치의 원인균으로 밝혀지고 있는 이 사슬알균은 설탕을 합성하는 능력을 가지고 있으며, 덱스트란(dextran)을 형성한다고 생각되는데, 이 덱스트란은 물에 녹지 않으며 끈적거리는 점착성이 있어 치태가 치아표면에 잘 붙어 있게 한다. 이 사슬알균은 설탕으로부터 유기산과 치태를 형성한다. 치태 중에는 사슬알균이 생산하는 산이 정체되어 있기 때문에, 이 산에 의해 치아 표면의 단단한 석회질을 녹인다. 대부분이 인산칼슘으로 구성되어 있는 치아의 표면은 산에 의해 칼슘이 분해되어 치아 표면이 거칠어지면서 충치가 진행된다. 이와 같이 세균과 이 세균이 생산하는 화학적 물질에 의해서 충치가 생긴다는 가설을 세균-화학설이라고 한다. 충치의 발생원인에는 이 세균-화학설 이외에도 미생물이 치아표면의 유기질 부위에 먼저 부착되어 산을 만들어 파괴시킨다는 단백용해설도 있으며, 또한 산에 의하지 않는 치아의 파괴, 음식물이 원인이 된다고 주장하는 학설도 있다. 설탕은 충치를 가장 잘 유발시키는 물질로, 섭취 빈도에 따라 충치가 증가한다는 것이 증명되고 있다. 비타민은 충치 요인에 그리 중요하지 않은 것으로 보이며 음식물 내에 존재하는 칼슘과 인 또한 중요하지 않다고 한다. 유전적 소인은 중요한 역할을 하리라 생각되지만 증명하기가 어렵다. |

| west | 1. The point in the heavens where the sun is seen to set at the equinox; or, the corresponding point on the earth; that one of the four cardinal points of the compass which is in a direction at right angles to that of north and south, and on the left hand of a person facing north; the point directly opposite to east. "And fresh from the west is the free wind's breath." (Bryant) 2. A country, or region of country, which, with regard to some other country or region, is situated in the direction toward the west. 3. Specifically: The Westen hemisphere, or the new World so called, it having been discovered by sailing westward from Europe; the Occident. Formerly, that part of the United States west of the Alleghany mountains; now, commonly, the whole region west of the Mississippi river; especially, that part which is north of the Indian Territory, new Mexico, etc. Usually with the definite article. West by north, West by south, according to the notation of the mariner's compass, that point which lies 11 1/4 deg to the north or south, respectively, of the point due west. West northwest, West southwest, that point which lies 22 1/2 deg to the north or south of west, or halfway between west and northwest or southwest, respectively. Origin: AS. West, adv.; akin to D.

| West African sleeping sickness | A chronic disease of humans caused by Trypanosoma brucei gambiense in northern and sub-Saharan Africa from Senegal east to Sudan and Uganda; characterised by splenomegaly, drowsiness, an uncontrollable urge to sleep, and the development of psychotic changes; basal ganglia and cerebellar involvement commonly lead to chorea and athetosis; the terminal phase of the disease is characterised by wasting, anorexia, and emaciation that gradually leads to coma and death, usually from intercurrent infection. Synonym: chronic African sleeping sickness, chronic trypanosomiasis, West African sleeping sickness, West African trypanosomiasis. (05 Mar 2000) |

| West Nile encephalitis virus | Caused by a virus in the family Flaviviridae. Synonym: West Nile virus. (05 Mar 2000) |
| west nile fever | <virology> A tropical disease caused by dengue virus (Arbovirus), that is transmitted by the bite of an infected mosquito of the genus Aedes). Four severity grades of the illness are seen: Grade I (fever and constitutional symptoms) Grade II (grade I plus spontaneous bleeding of skin, gums or gastrointestinal tract) Grade III (grade II plus agitation and circulatory failure) Grade IV (profound shock). Grade I infection is seen most frequently in world travelers, where it is usually self-limited and rarely fatal. The other grades are referred to as dengue haemorrhagic fever and are often fatal. Dengue haemorrhagic fever appears to be an infection by one of the other dengue viruses. Prior immunity to a different dengue virus type appears to be important in the development of the more serious haemorrhagic form. Vaccines are available. Protection from mosquitoes is an important preventive measure. (27 Sep 1997) |
| west nile virus | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), which produces encephalitis experimentally when inoculated into some rodents, chicks, birds, or monkeys. In humans, it is seen most frequently in africa, asia, and europe presenting as a silent infection or undifferentiated fever (west nile fever). It is transmitted by culex spp mosquitoes.
