| 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. |

| Pahvant Valley fever | <infectious disease, microbiology> A rare infection of rabbits and rodents caused by the bacteria Francisella tularensis. Francisella tularensis is found in many animals (rabbits, rodents) and may be transmitted by direct contact or via insect bite (ticks and deer-fly). Humans can also contract the illness via the direct contact with the infected animal carcass (break in the skin). The illness is characterised by an ulcerative lesion at the site of the inoculation with regional lymph node swelling, pneumonia, fever, chills, headache, muscle pains and joint stiffness. Risk factors include an exposure to rabbits or recent tick bite. A vaccine is available for high risk workers. Treatment is with streptomycin or tetracycline. Tularaemia is fatal in 5% of untreated cases and in less than 1% of treated cases. Incidence: less than 200 cases per year (USA). Origin: Gr. Haima = blood (18 Jul 2002) |

| valley | Origin: OE. Vale, valeie, OF. Valee, valede, F. Vallee, LL. Vallata, L. Vallis, valles. See Vale. 1. The space inclosed between ranges of hills or mountains; the strip of land at the bottom of the depressions intersecting a country, including usually the bed of a stream, with frequently broad alluvial plains on one or both sides of the stream. Also used figuratively. "The valley of the shadow of death." (Ps. Xxiii. 4) "Sweet interchange Of hill and valley, rivers, woods, and plains." (Milton) Deep and narrow valleys with abrupt sides are usually the results of erosion by water, and are called gorges, ravines, canons, gulches, etc. 2. The place of meeting of two slopes of a roof, which have their plates running in different directions, and form on the plan a reentrant angle. The depression formed by the meeting of two slopes on a flat roof. Valley board, a roof having one or more valleys. See Valley, 2, above. Source: Websters Dictionary (01 Mar 1998) |
| valley fever | A fungal infection caused by the fungus Coccidioides immitis. Exists in two forms: primary disease, which is a self-limited respiratory infection (requires no treatment) and a progressive form (diffuse and granulomatous), that can involve almost any part of the body. Approximately 60% of infections cause no symptoms and are identified only by skin testing. Immunocompromised patients (AIDS) are at greatest risk for disseminated disease. Symptoms include cough, anorexia, fever, weight loss and joint pains. Complications include pleural effusion and dissemination. There is a poor prognosis for disseminated disease. Treatment includes amphotericin B for lung infection. Itraconazole and fluconazole are also useful agents. (27 Sep 1997) |
| valley segment | That portion of a stream network with similar morphologies and governing geomorphic processes identified by valley bottom and sideslope geomorphic characteristics. (05 Dec 1998) |
