| 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. |

| 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) |

| maximum urea clearance | The urea clearance when the urine flow exceeds 2 ml/min; normal value is about 75 ml blood/min per 1.73 m2 body surface area. (05 Mar 2000) |
| herbicides, urea | Herbicides which owe their activity to the urea moiety in the molecule. (12 Dec 1998) |
| standard urea clearance | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula. (05 Mar 2000) |
| quinine and urea hydrochloride | Sclerosing agent for treatment of internal haemorrhoids, hydrocele, and varicose veins, containing not less than 58% and not more than 65% of anhydrous quinine. (05 Mar 2000) |
| urea | <biochemistry> The final nitrogenous excretion product of many organisms. (18 Nov 1997) |
| urea breath test | A test for the presence of the bacteria helicobacter pylori that causes inflammation and ulcers in the stomach. The breath test is based on the ability of h. Pylori to break down urea. Ten minutes after swallowing a capsule containing urea with labelled carbon, a breath sample is collected to detect labelled carbon in the exhaled breath. A positive test indicates active infection. The test turns negative after eradication of the bacteria from the stomach with antibiotics. (12 Dec 1998) |
| urea clearance | The volume of plasma (or blood) that would be completely cleared of urea by one minute's excretion of urine; originally calculated as urine flow multiplied by urine urea concentration divided by concentration of urea in whole blood rather than plasma, representing blood urea clearance rather than plasma urea clearance. (05 Mar 2000) |
| urea clearance test | A test of renal function based on urea clearance. (05 Mar 2000) |
| urea cycle | The metabolic pathway isfound in vertebrates and takes place in theliver, in it, urea is synthesised from amino acids and carbon dioxide. (09 Oct 1997) |
| urea peroxide | CH4N2O-H2O2;a white crystalline compound used in an aqueous solution as an oxidizing mouthwash. (05 Mar 2000) |
| urea stibamine | A urea derivative of stibanilic acid, used in the treatment of kala azar and certain other tropical diseases. (05 Mar 2000) |
| agar | <cell culture, chemical, microbiology> This gelatinous material, an extract from red algae (mainly Gelidium and Gracilaria species), is most frequently used as a culture medium, especially for bacteria. It is also used as a thickener in foods, but humans cannot digest it. (06 May 1997) |
| agar-gel reaction | <immunology> The reaction between an antibody and an antigen during an immunology lab procedure where the two are allowed to diffuse toward each other through an agar-gel medium. Lines of precipitation form in the places on the gel where the two react with each other and shows where the reaction has occurred. (09 Oct 1997) |
| ascitic agar | A form of serum agar. (05 Mar 2000) |
| urea agar of Christensen |
