| 영문 | complement fixation reaction | 한글 | 보체결합 반응, 도움체결합반응 |
|---|---|---|---|
| 설명 | 항체와의 반응에 있어서 보체와 결합하는 항체를 검사하는 방법으로, 이 반응은 최초에 기지항원, 피검혈청 및 보체를 혼합한다. 제2단계에서는 적혈구와 이것에 대응하는 용혈소의 혼합액을 가한다. 본 반응후 용혈이 일어나지 않으면 본체는 항원항체결합물에 결합한 것이 되어 양성이 되지만, 용혈이 일어난 경우 보체는 결합하지 않아 소비되지 않기 때문에 음성이 된다. 본 반응은 기지혈청을 써서 항원검출에 응용할 수 있으며, 마이코플라스마, 리케챠, 클라미디아, 바이러스, 매독 등의 진단에 쓰인다. |

| nitrogen dioxide | <chemical> Nitrogen oxide (no2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting oedema several days later may cause death. It is a major atmospheric pollutant that is able to absorb uv light that does not reach the earth's surface. Pharmacological action: oxidants, photochemical, poisons. Chemical name: Nitrogen oxide (NO2) (12 Dec 1998) |

| nitrogen distribution | Determination of the distribution of nitrogen in the urine among the various constituents. Synonym: nitrogen distribution. (05 Mar 2000) |
| nitrogen equivalent | The nitrogen content of protein; used in calculating the protein breakdown in the body from the nitrogen excreted in the urine, 1 g of nitrogen considered as having originated in 6.25 g of protein catabolised. (05 Mar 2000) |
| nitrogen group | Five trivalent or quinquivalent elements whose hydrogen compounds are basic and whose oxyacids vary from monobasic to tetrabasic: nitrogen, phosphorus, arsenic, antimony, and bismuth. (05 Mar 2000) |
| nitrogen isotopes | Stable nitrogen atoms that have the same atomic number as the element nitrogen, but differ in atomic weight. N-15 is a stable nitrogen isotope. (12 Dec 1998) |
| nitrogen lag | The length of time after the ingestion of a given protein before the amount of nitrogen equal to that in the protein has been excreted in the urine. (05 Mar 2000) |
| nitrogen monoxide | <chemical> Nitrogen oxide (n2o). A colourless, odourless gas that is used as an anaesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream. Pharmacological action: aerosol propellants, analgesics, non-narcotic, anaesthetics, inhalation. Chemical name: Nitrogen oxide (N2O) (12 Dec 1998) |
| nitrogen mustard compounds | <chemical> A group of alkylating agents derived from mustard gas, with the sulfur replaced by nitrogen. They were formerly used as toxicants and vesicants, but now function as antineoplastic agent. These compounds are also powerful mutagens, teratogens, immunosuppressants, and carcinogens. Pharmacological action: antineoplastic agent, alkylating, carcinogens, mutagens, teratogens. (12 Dec 1998) |
| nitrogen mustards | <pharmacology> A series of tertiary amine compounds having vesicant properties similar to those of mustard gas. They have the general formula RN(CH2CH2Cl)2. They can alkylate compounds such as DNA and are used as the basis of cytostatic drugs for cancer chemotherapy. (18 Nov 1997) |
| nitrogen narcosis | Narcosis produced by nitrogenous materials such as occurs in certain forms of uraemia and hepatic coma, the stuporous condition characterised by disorientation and by loss of judgment and skill, attributed to an increased partial pressure of nitrogen in the inspired air of deepsea divers during underwater operations. Commonly referred to as "rapture of the deep." (05 Mar 2000) |
| nitrogen oxides | Inorganic oxides that contain nitrogen. (12 Dec 1998) |
| nitrogen partition | Determination of the distribution of nitrogen in the urine among the various constituents. Synonym: nitrogen distribution. (05 Mar 2000) |
| nitrogen radioisotopes | Unstable isotopes of nitrogen that decay or disintegrate emitting radiation. N atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes. (12 Dec 1998) |
| nonprotein nitrogen | The nitrogen content of other than protein bodies; e.g., about one-half the nonprotein nitrogen in the blood is contained in urea. Synonym: rest nitrogen. (05 Mar 2000) |
| undetermined nitrogen | The nitrogen of blood, urine, etc., other than urea, uric acid, amino acids, etc., that can be directly estimated; in blood it amounts to about 25 mg per 100 ml. Urea nitrogen, the portion of nitrogen in a biological sample, such as blood or urine, that derives from its content of urea. See: blood urea nitrogen. (05 Mar 2000) |
