| 영문 | nitrogenous waste | 한글 | 질소폐기물 |
|---|---|---|---|
| 설명 | 인체내 소화기관으로 넘어온 음식물은 크게 탄수화물, 지방, 단백질 3가지로 대분된다. 이중 단백질은 질소성분이 포함되어 있어 대사과정에서 질소폐기물을 생성하게 된다. 이런 질소폐기물은 인체내에 유해하여 꼭 체외로 방출되어져야 하는데, 이런 작용을 콩팥에서 수행한다. 예를 들면, 대표적인 질소폐기물로써 요소가 있는데, 단백질은 분해되어져 간에서 요소로 바뀌어지고, 생성된 요소는 신장을 거쳐 소변으로 배설된다. |

| 영문 | blood urea nitrogen | 한글 | 혈액요소질소 |
|---|---|---|---|
| 설명 | 요소는 아미노산의 탈아미노에 의해 생긴 암노니아와 탄산가스로부터 간에서 합성된다. 혈중에서는 혈장과 혈구의 물성분 안에 함유되어 있다. 혈액요소질소는 콩팥토리에서 여과되며 일부 요세관에서 재흡수되고, 나머지가 오줌중에 배설된다. 따라서 혈액요소질소는 콩팥기능의 저하에 따라 증가되지만, 식사단백질 섭취량, 조직붕괴, 위장관 출혈 등과 탈수 등 순환혈액량의 이상으로 변동된다. |

| 영문 | blood urea nitrogen(BUN) | 한글 | 혈중요소질소 |
|---|---|---|---|
| 설명 | 혈액속의 요소를 말한다. 요소란 단백질이나 아미노산의 최종산물로써 간에서 생산되어 콩팥으로 배출되는 물질이다. 이것은 인간에게 없어서는 안될 단백질과 아미노산의 산물이므로 사람에겐 언제나 일정량이 생산된다. 콩팥의 기능이 나쁠 경우에는 이것이 콩팥으로 배설되지 못하고 몸속에 축적된다. 그러므로 콩팥의 기능측정에 이것이 이용 된다. |

| nitrogen | <chemistry> A colourless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organised living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva. Origin: L. Nitrum natron + -gen: cf. F. Nitrogene. See Niter. Source: Websters Dictionary (01 Mar 1998) |

| nitrogen balance | The difference between the total nitrogen intake by an organism and its total nitrogen loss. A normal, healthy adult has a zero nitrogen balance, Nin Nout (i.e., a positive nitrogen balance. (05 Mar 2000) |
| nitrogen compounds | Inorganic compounds that contain nitrogen as an integral part of the molecule. (12 Dec 1998) |
| nitrogen cycle | <biochemistry> The global cycle of moving various forms of nitrogen through the air, water, soil, plants, animals of the planet. See: nitrogen fixation. (09 Oct 1997) |
| 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 fixation | <biochemistry> The incorporation of atmospheric nitrogen into ammonia by various bacteria, catalysed by nitrogenase. This is an essential stage in the nitrogen cycle and is the ultimate source of all nitrogen in living organisms. In the sea, the main nitrogen fixers are Cyanobacteria. There are several free living bacteria in soil that fix nitrogen including species of Azotobacter, Clostridium and Klebsiella. Rhizobium only fixes nitrogen when in symbiotic association, in root nodules, with leguminous plants. The oxygen sensitive nitrogenase is protected by plant produced leghaemoglobin and the plant obtains fixed nitrogen from the bacteria. See: Frankia. (18 Nov 1997) |
| 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) |
| blood urea nitrogen | Blood urea nitrogen (BUN) is a metabolic by product (in the liver) from the breakdown of blood, muscle and protein. Blood urea nitrogen can be measured from a simple venipuncture specimen. Abnormal elevation in the blood urea nitrogen can indicate renal disease, dehydration, congestive heart failure, gastrointestinal bleeding, starvation, shock or urinary tract obstruction (by tumour or prostate gland). Low BUN level can indicate liver disease, malnutrition or a low protein diet. Normal BUN levels should be between 7 and 20 mg/dl (milligrams per decilitre). (27 Sep 1997) |
