|---|---|---|---|
| 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. |

| ammonia assimilation | The utilization of ammonia (or ammonium ions) in the net synthesis of nitrogen-containing molecules; e.g., glutamine synthetase. Synonym: ammonia fixation. (05 Mar 2000) |

| assimilation | 1. The act or process of assimilating or bringing to a resemblance, likeness, or identity; also, the state of being so assimilated; as, the assimilation of one sound to another. "To aspire to an assimilation with God." (Dr. H. More) "The assimilation of gases and vapors." (Sir J. Herschel) 2. <physiology> The conversion of nutriment into the fluid or solid substance of the body, by the processes of digestion and absorption, whether in plants or animals. "Not conversing the body, not repairing it by assimilation, but preserving it by ventilation." (Sir T. Browne) The term assimilation has been limited by some to the final process by which the nutritive matter of the blood is converted into the substance of the tissues and organs. Origin: L. Assimilatio: cf. F. Assimilation. Source: Websters Dictionary (01 Mar 1998) |
| assimilation pelvis | A deformity in which the transverse processes of the last lumbar vertebra are fused with the sacrum, or the last sacral with the first coccygeal body. (05 Mar 2000) |
| genetic assimilation | <genetics> A situation in which a characteristic that is normally expressed only in certain environmental situations becomes fixed in a population so that it no longer requires environmental factors to be expressed. (07 May 1998) |
| reproductive assimilation | In sensorimotor theory, an active cognitive process by which past experience is applied to novel situations. (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) |
| carbon-nitrogen ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-nitrogen bond. Registry number: EC 6.3 (12 Dec 1998) |
| carbon-nitrogen ligases with glutamine as amide-n-donor | <enzyme> Enzymes that catalyze the joining of glutamine-derived ammonia and another molecule. The linkage is in the form of a carbon-nitrogen bond. Registry number: EC 6.3.5 (12 Dec 1998) |
| carbon-nitrogen lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-nitrogen bond by means other than hydrolysis or oxidation. Subclasses are the ammonia-lyases, the amidine-lyases, the amine-lyases, and other carbon-nitrogen lyases. Registry number: EC 4.3 (12 Dec 1998) |
| genes, nitrogen fixation | Regulatory and structural genes present in certain bacteria, algae and fungi that control the conversion of atmospheric nitrogen into biologically usable compounds; include nif structural genes (e.g., nifd, nifh) for nitrogenase and nitrate reductase as well as regulator genes nifa, nifb, ntra, ntrb, ntrc. Some are responsible for regulating transcription of genes involved in the assimilation of poor nitrogen sources in enteric bacteria. (12 Dec 1998) |
| rest 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) |
| heavy nitrogen | The less common stable nitrogen isotope, making up 0.37% of natural nitrogen. Synonym: heavy nitrogen. (05 Mar 2000) |
| 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-13 | A cyclotron-produced, positron-emitting radioisotope of nitrogen with a half-life of 9.97 minutes; used in protein metabolism studies and in positron-emission tomography. (05 Mar 2000) |
| nitrogen-14 | The common nitrogen isotope, making up 99.63% of natural nitrogen. (05 Mar 2000) |
