| 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. |

| acid dissociation constant | <chemistry> This is the equilibrium constant for the breaking apart of a weak acid into its hydrogen and conjugate base in a water solution. (09 Oct 1997) |
| Ambard's constant | <physiology> Obsolete law's for output of urea: 1. With the urinary urea concentration constant, urea output varies directly as the square of the concentration of the blood urea. 2. With the blood urea concentration constant, urea output varies inversely as the square root of its urinary concentration. (05 Mar 2000) |
| association constant | <chemistry> Reciprocal of dissociation constant. A measure of the extent of a reversible association between two molecular species at equilibrium. (18 Nov 1997) |
| Avogadro's constant | <physics> The number of molecules in a mole (gram molecular weight) of a substance, equals 6.02 x 1023 molecules. (09 Oct 1997) |
| base dissociation constant | <chemistry> This is the equilibrium constant for the reaction in which a weak base breaks apart in water to form its conjugate acid and hydroxide ion. (09 Oct 1997) |

| boltzmann constant | <radiobiology> K = 1.38 x 10^-16 erg/degree. This is the ratio of the universal gas constant to Avogadro's number. It is also used to relate temperatures (Kelvin) to energies (ergs or Joules) via E = (constant of order unity) kT. (09 Oct 1997) |
| radioactive constant | <physics, radiobiology> The fraction of the amount of a radionuclide that undergoes transition per unit time. Formally: Lamda=dP/dt Where dP is the probability of a given nucleus undergoing spontaneous nuclear transition in the time interval dt. (16 Dec 1997) |
| permeability constant | A measure of the ease with which an ion can cross a unit area of membrane driven by a 1.0 m difference in concentration; usually expressed in centimeters per second. Compare: permeability coefficient. (05 Mar 2000) |
| Michaelis constant | <chemistry> The true dissociation constant for the enzyme-substrate binary complex in a single-substrate rapid equilibrium enzyme-catalyzed reaction (usually symbolised by Ks), the concentration of the substrate at which half the true maximum velocity of an enzyme-catalyzed reaction is achieved (when velocities are measured under initial rate and steady state conditions). The ratio of rate constants (k2 + k3)/k1 in the single-substrate enzyme-catalyzed reaction: E + S &dblarr; ES &dblarr; E + products where E represents the free enzyme, S is the substrate, and ES is the central binary complex. The expression for the Michaelis constant will be more complex for multisubstrate reactions. An apparent Michaelis constant is a constant determined either under conditions that are not strictly steady state and initial rate or one that varies with the concentration of one or more cosubstrates. See: Michaelis-Menten equation. Synonym: Michaelis-Menten constant. (05 Mar 2000) |
