| 설명 | 일산화탄소의 흡입에 의하여 산화헤모글로빈이 카르복시헤모글로빈으로 변화함으로써 일어나는 중독. 중추신경계장애를 일으키고 죽음에 이르기고 한다. 일산화탄소는 탄소를 함유한 유기물이 불완전연소할 때 발생한다. 따라서 제철, 도시가스 제조, 가정에서 발생하며 자동차 배기가스에도 포함되어 있고 가정에서 연료의 연소에 의해서도 생긴다. 일산화탄소를 흡입하면 폐에서 혈액속의 혈색소와 결합하여 일산화탄소헤모글로빈을 형성하고, 이 때문에 혈액의 산소운반능력이 상실되어 내부적인 질식상태에 빠지게 된다. 일산화탄소와 헤모글로빈과의 친화성은 극히 강하여 산소보다 250배의 세기로 결합한다. 사람에 따라 일산화탄소에 대한 감수성이 다르지만, 공기 속에 0.001%만 들어있어도 중독을 일으킨다. 또 0.06%에서는 1시간만 흡입하면 두통을 일으키고 2시간이면 실신한다. 또 0.1%을 경우는 1시간 이내에 실신하고 4시간이면 사망한다. 중독 증세는 조직의 무산소증에 의한 것으로서, 급성중독은 급격히 사망하는 수도 있지만, 대개는 처음에 두통-현기증-귀울림-구역-구토 등이 있고, 사지의 운동이 불가능하게 되며, 다소의 의식이 남아 있어도 그대로 죽음에 이르게 된다. 타각적으로는 얼굴에 홍조를 띠고 전신에 무늬 모양의 발적이 나타나며, 호흡이 가늘고 불규칙하게 된다. 코를 골고 체온이 내려가고 전신의 근육 이온 등이 보이며, 호흡곤란의 증세가 보이지 않는 중에 호흡이 정지하게 된다. |

| carbon-carbon double bond isomerases | <enzyme> Enzymes that catalyze the shifting of a carbon-carbon double bond from one position to another within the same molecule. Registry number: EC 5.3.3 (12 Dec 1998) |
|---|---|
| carbon-carbon ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-carbon bond. These are the carboxylating enzymes and are mostly biotinyl-proteins. Registry number: EC 6.4 (12 Dec 1998) |
| carbon-carbon lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-carbon bond by means other than hydrolysis or oxidation. This subclass contains the decarboxylases, the aldehyde-lyases, and the oxo-acid-lyases. Registry number: EC 4.1 (12 Dec 1998) |
| atomic number | <chemistry> Symbol Z. The number of protons in the nucleus of an atom and also its characteristic atomic number. The atomic numbers of the known elements form a complete series from 1 (hydrogen) to 103 (lawrencium). (16 Dec 1997) |
| Avogadro's number | <physics> The number of molecules in a mole (gram molecular weight) of a substance, equals 6.02 x 1023 molecules. (09 Oct 1997) |
| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.

| burst number | The number of viral particles that emerge from a cell after a viralinfection has burst it open. (09 Oct 1997) |
| Mach number | A number representing the ratio between the speed of an object moving through a fluid medium, such as air, and the speed of sound in the same medium. (05 Mar 2000) |
| magnetic mach number | <physics> A dimensionless number equal to the ratio of the velocity of a fluid to the velocity of Alfven waves in that fluid. (13 Nov 1997) |
| mass number | The mass of the atom of a particular isotope relative to hydrogen-1 (or to 1/12 the mass of carbon-12), generally very close to the whole number represented by the sum of the protons and neutrons in the atomic nucleus of the isotope (indicated in the name or symbol of the isotope; e.g., oxygen-16, 16O); not to be confused with the atomic weight of an element, which may include a number of isotopes in natural proportion. (05 Mar 2000) |
| Reichert-Meissl number | An index of the volatile acid content of a fat; the number of milliliters of 0.1 n KOH required to neutralise the soluble volatile fatty acids in 5 g of fat that has been saponified, acidified to liberate the fatty acids, and then steam-distilled. Synonym: volatile fatty acid number. (05 Mar 2000) |
| volatile fatty acid number | An index of the volatile acid content of a fat; the number of milliliters of 0.1 n KOH required to neutralise the soluble volatile fatty acids in 5 g of fat that has been saponified, acidified to liberate the fatty acids, and then steam-distilled. Synonym: volatile fatty acid number. (05 Mar 2000) |
| gold number | A unit of power of the protective colloids; the number of milligrams of protective colloid just sufficient to prevent the precipitation of 10 ml of a 0.0053 to 0.0058% gold solution by the action of 1 ml of a 10% sodium chloride solution. Synonym: gold number. (05 Mar 2000) |
| Reynolds number | A dimensionless number that describes the tendency for a flowing fluid, such as blood, to change from laminar flow to turbulent flow or vice versa. (05 Mar 2000) |
| Reynold's number | <physiology> A constant without dimensions that relates the inertial and viscous drag acting to hinder a body moving through fluid medium. For cells the Reynold's number is very small, viscous drag is dominant and inertial resistance can be neglected. (18 Nov 1997) |
