|---|---|---|---|
| 설명 | 무산소상태 또는 산소결핍상태, 생체조직 속의 산소가 완전히 없는 상태를 의미하며, 이는 회복할 수 없는 조직손상을 가져오고 심하면 조직괴사를 일으킨다. 뇌에 대한 산소공급이 부적절하면 세포는 죽게되고, 산소나 포도당의 전달이 완전히 정지되기 전에 뉴런의 일부가 죽기 시작한다. 임신중의 무산소증은 뇌성마비의 주요한 원인이 되고, 무산소증에 의한 뇌손상은 간질의 원인이 된다. 조직사망에 이르기까지의 시간은 손상받은 조직의 신진대사율에 따라 다르다. 즉 뇌손상은 가장 빨라야 4~5분 걸리고, 그 외 심장과 망막도 산소결핍에 민감하다. 원인인자로는 허파병, 순환기 병에 의한 동맥혈의 산소포화가 충분치 않는 것, 빈혈에 의한 산소운반부족, 울혈, 허혈에 의한 것, 조직에서의 산소수요의 증대, 또는 산소이용불능 등이 있다. 빠른맥, 호흡촉박, 정신장애를 초래하고, 방치하면 사망한다. 원인의 제거, 산소마스크, 산소텐트 등 충분히 산소를 공급하여 주는 것이 필요하다. 무산소증은 세가지 종류가 있다. ① 질식성 무산소증은 혈류는 적절하지만, 산소의 전달이 부적절할 때, ② 허혈성 무산소증은 산소의 함량은 적절하지만 혈류의 저하가 있을 때, ③ 세포독성 무산소증은 혈액 내 산소함량은 정상이지만 산소의 이용 능력이 방해를 받는 것을 말한다. |

demand anoxia
| diffusion anoxia | Diffusion hypoxia severe enough to result in the absence of oxygen in alveolar gas. (05 Mar 2000) |
|---|
| anaemic anoxia | A term formerly considered synonymous with anaemic hypoxia, but now reserved for extremely severe cases in which oxygen is almost completely lacking. (05 Mar 2000) |
|---|---|
| anoxia | <physiology> A total lack of oxygen, often used interchangeably with hypoxia to mean a reduced supply of oxygen to the tissues. (18 Nov 1997) |
| anoxia neonatorum | Any anoxia observed in newborn infants. (05 Mar 2000) |
| anoxic anoxia | A term formerly considered synonymous with hypoxic hypoxia, but now reserved for extremely severe cases in which oxygen is almost completely lacking. (05 Mar 2000) |
| cerebral anoxia | A reduced supply of oxygen to the brain. (12 Dec 1998) |
| histotoxic anoxia | Poisoning of the respiratory enzyme systems of the tissues, as in the inhibition of cytochrome oxidase by cyanides; owing to the inability of tissue cells to utilise oxygen, its tension in arterial and capillary blood is usually greater than normal. (05 Mar 2000) |
| stagnant anoxia | Stagnant hypoxia severe enough to result in the absence of oxygen in tissues. (05 Mar 2000) |
| oxygen affinity anoxia | Anoxia due to inability of haemoglobin to release oxygen. (05 Mar 2000) |
| foetal anoxia | Foetal oxygen deficiency. (12 Dec 1998) |
| ambipolar diffusion | <radiobiology> Diffusion process in which buildup of spatial charge creates electric fields which cause electrons and ions to leave the plasma at the same rate. (Such electric fields are self-generated by the plasma and act to preserve charge neutrality.) (09 Oct 1997) |
| anomalous diffusion | <radiobiology> Diffusion in most plasma devices, particularly tokamaks, is higher than what one would predict from understood causes. The observed, typical diffusion is referred to as anomalous because it has not yet been explained. Anomalous diffusion includes all diffusion which is not due to collisions and geometric effects. While such effects were not understood when the term was coined, and most still are not, diffusion due to well-understood wave phenomena is still 'anomalous'. Classical diffusion and Neo-classical diffusion are the two well-understood diffusion theories, although neither is adequate to fully explain the observed anomalous diffusion. See: entries for classical diffusion and neoclassical diffusion. Anomalous resistivity (09 Oct 1997) |
| bohm diffusion | <radiobiology> A rapid loss of plasma across magnetic field lines caused by microinstabilities. Theory formulated by the physicist David Bohm. Semiempirical formula for the diffusion coefficient given by Bohm in 1946 (noted by Bohm, Burhop, and Massey, who were developing a magnetic arc for use in uranium isotope separation). Bohm diffusion was proposed (not derived from first principles) to scale as 1/B rather than the 1/B^2 scaling predicted by classical diffusion. A 1/B scaling results from assuming that particles diffuse across field lines at an optimum rate (effective collision frequency=cyclotron frequency). The 1/B scaling is observed (approximately) in most reactors. See: diffusion, microinstabilities, field lines. (09 Oct 1997) |
| gel diffusion | Diffusion in a gel, as in the case of gel diffusion precipitin tests in which the immune reactants diffuse in agar. See: immunodiffusion. (05 Mar 2000) |
| gel diffusion precipitin tests | Precipitin test's in which the immune precipitate forms in a gel medium (usually agar) into which one or both reactants have diffused; generally classified in two types, in one dimension, and in two dimensions. Synonym: gel diffusion reactions. (05 Mar 2000) |
| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension).
