| 영문 | uric acid | 한글 | 요산 |
|---|---|---|---|
| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

|---|---|---|---|
| 설명 | 항산성성질(좀처럼 염색이 되지 않으나 한번 염색이 되면 산성용액에 의해서 탈색이 되지 않는 성질)을 가진 균(예를 들면 결핵균 등)의 검출에 이용되는 염색방법. 방법에는 Ziehl-Neelson법과 Kinyoun법 등이 있다. |

| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| iron-binding capacity | The capacity of iron-binding protein in serum (transferrin) to bind serum iron. (05 Mar 2000) |
|---|---|
| iron chelating agents | Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of haemoglobin is an example of a metal chelate found in biological systems. (12 Dec 1998) |
| iron compounds | Inorganic compounds that contain iron as an integral part of the molecule. (12 Dec 1998) |
| iron deficiency | Deficiency of iron results in anaemia because iron is necessary to make haemoglobin, the key molecule in red blood cells responsible for the transport of oxygen. In iron deficiency anaemia, the red cells are unusally small (microcytic) and pale (hypochromic). Characteristic features of iron deficiency anaemia in children include failure to thrive (grow) and increased infections. The treatment of iron deficiency anaemia , whether it be in children or adults, is with iron and iron-containing foods. Food sources of iron include meat, poultry, eggs, vegetables and cereals (especially those fortified with iron). According to the National Academy of Sciences, the recommended dietary allowances of iron are 15 milligrams per day for women and 10 milligrams per day for men. (12 Dec 1998) |
| iron deficiency anaemia | Hypochromic microcytic anaemia characterised by low serum iron, increased serum iron-binding capacity, decreased serum ferritin, and decreased marrow iron stores. Synonym: hypoferric anaemia. (05 Mar 2000) |
| iron-dextran complex | <chemical> Iron dextran. A complex of ferric oxyhydroxide with dextrans of 5000 to 7000 daltons in a viscous solution containing 50 mg/ml of iron. It is supplied as a parenteral preparation and is used as a haematinic. (goodman and gilman's the pharmacological basis of therapeutics, 8th ed, p1292) Pharmacological action: haematinics. Chemical name: Iron dextran (12 Dec 1998) |
| iron dextrin | A complex of dextrin with ferric hydroxide; used intravenously in the treatment of iron deficiency. (05 Mar 2000) |
| iron, dietary | Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins haemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anaemia. (12 Dec 1998) |
| iron excess | Iron overload can damage the heart, liver, gonads and other organs. Iron overload is a particular risk in people who may have certain genetic conditions (haemochromatosis) sometimes without knowing it and also in people receiving recurrent blood transfusions. According to the national academy of sciences, the recommended dietary allowances of iron are 15 milligrams per day for women and 10 milligrams per day for men. (12 Dec 1998) |
| iron haematoxylin | Unique ferric lakes of haematein that produce deep blue-black stains; useful for studies of cytologic detail, such as chromosomes, spindle fibres, Golgi apparatus, myofibrils, and mitochrondria; also useful to demonstrate Entamoeba histolytica. See: Heidenhain's iron haematoxylin stain, Weigert's iron haematoxylin stain. (05 Mar 2000) |
| iron-hearted | Hard-hearted; unfeeling; cruel; as, an iron-hearted master. Source: Websters Dictionary (01 Mar 1998) |
| iron index | An obsolete index of iron obtained by dividing the figure for the average content of iron in normal blood (42.74 mg) by the red cell count in millions; it normally varies between 8 and 9; in pernicious anaemia, the index is usually greater than 10, but it tends to be normal in chronic secondary anaemia. (05 Mar 2000) |
| iron isotopes | Stable iron atoms that have the same atomic number as the element iron, but differ in atomic weight. Fe-54, 57, and 58 are stable iron isotopes. (12 Dec 1998) |
| iron lung | A mechanical respirator in which the body except the head is encased within a metal tank, which is sealed at the neck with an airtight gasket; artificial respiration is induced by making the air pressure inside negative. Synonym: iron lung, tank respirator. (05 Mar 2000) |
| iron metabolism disorders | Disorders in the processing of iron in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
