|---|---|---|---|
| 설명 | 다발성 원발성골종양. 머리뼈-갈비뼈-복장뼈-척추뼈-골반 등에 잘 나타나고, 물렁물렁한 종괴를 형성하며, 뼈의 흡수가 일어나고, 40~60세 남자에게 많이 발생한다. 골수종 종양세포는 형질세포에서 유래한 것이어서 형질세포종이라고도 한다. 과거에는 형질세포성골수종 이외에는 다른 골수조혈요소에서 생기는 골수종이라고 생각했지만 현재는 부정되고 있다. 형질세포는 원래 면역글로불린을 생산하는 세포이며, 그것이 종양화한 다발 골수종 환자에서도 대부분 혈청 속에 면역 글로불린이 증가된 것을 볼 수 있다. 증가한 글로불린은 IgG나 IgA인 경우가 많지만 다른 형도 있다. 골수종 환자 약 50%는 오줌에서 벤스죤스단백질이 검출되는데, 이 단백질의 축적에 의해 요세관이 파괴되고, 콩팥경화가 일어난다. 골수종 환자에서는 혈청단백 이상으로 가끔 아밀로이드증이 나타난다. 뼈 X선 소견으로서는 도려낸 병터, 골융해상, 병적골절이 관찰된다. |

| spiegel iron | <chemistry> A fusible white cast iron containing a large amount of carbon (from three and a half to six per cent) and some manganese. When the manganese reaches twenty-five per cent and upwards it has a granular structure, and constitutes the alloy ferro manganese, largely used in the manufacture of Bessemer steel. Synonym: specular pig iron, spiegel, and spiegeleisen. Origin: G. Spiegel mirror + E. Iron. Source: Websters Dictionary (01 Mar 1998) |

| non-haem iron protein | <biochemistry> Any protein containing iron but not any haem iron; e.g., NADH dehydrogenase. They are often found in oxidation-reduction reactions, and contain iron but no porphyrin groups. (17 Jul 2002) |
| deficiency, iron | 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 | 1. To smooth with an instrument of iron; especially, to smooth, as cloth, with a heated flatiron; sometimes used with out. 2. To shackle with irons; to fetter or handcuff. "Ironed like a malefactor." 3. To furnish or arm with iron; as, to iron a wagon. Origin: Ironed; Ironing. 1. Of, or made of iron; consisting of iron; as, an iron bar, dust. 2. Resembling iron in colour; as, iron blackness. 3. Like iron in hardness, strength, impenetrability, power of endurance, insensibility, etc.; as: Rude; hard; harsh; severe. "Iron years of wars and dangers." (Rowe) "Jove crushed the nations with an iron rod." (Pope) Firm; robust; enduring; as, an iron constitution. Inflexible; unrelenting; as, an iron will. Not to be broken; holding or binding fast; tenacious. "Him death's iron sleep oppressed." Iron is often used in composition, denoting made of iron, relating to iron, of or with iron; producing iron, etc.; resembling iron, literally or figuratively, in some of its properties or characteristics; as, iron-shod, iron-sheathed, iron-fisted, iron-framed, iron-handed, iron-hearted, iron foundry or iron-foundry. Iron age. Common pyrites, or pyrite. See Pyrites. Iron sand, an iron ore in grains, usually the magnetic iron ore, formerly used to sand paper after writing. Iron scale, the thin film which on the surface of wrought iron in the process of forging. It consists essentially of the magnetic oxide of iron, Fe3O4>. Iron works, a furnace where iron is smelted, or a forge, rolling mill, or foundry, where it is made into heavy work, such as shafting, rails, cannon, merchant bar, etc. Origin: AS. Iren, isen. See Iron. 1. <chemistry> The most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc), or a hydrous oxide (as limonite, turgite, etc). It is reduced on an enormous scale in three principal forms; viz, cast iron, steel, and wrought iron. Iron usually appears dark brown, from oxidation or impurity, but when pure, or an fresh surface, is a gray or white metal. It is easily oxidized (rusted) by moisture, and is attacked by many corrosive agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9. Specific gravity, pure iron.86; cast iron.1. In magnetic properties, it is superior to all other substances. The value of iron is largely due to the facility with which it can be worked. Thus, when heated it is malleable and ductile, and can be easily welded and forged at a high temperature. As cast iron, it is easily fusible; as steel, is very tough, and (when tempered) very hard and elastic. Chemically, iron is grouped with cobalt and nickel. Steel is a variety of iron containing more carbon than wrought iron, but less that cast iron. It is made either from wrought iron, by roasting in a packing of carbon (cementation) or from cast iron, by burning off the impurities in a Bessemer converter (then called Bessemer steel), or directly from the iron ore (as in the Siemens rotatory and generating furnace). 2. An instrument or utensil made of iron; chiefly in composition; as, a flatiron, a smoothing iron, etc. "My young soldier, put up your iron." (Shak) 3. Fetters; chains; handcuffs; manacles. "Four of the sufferers were left to rot in irons." (Macaulay) 4. Strength; power; firmness; inflexibility; as, to rule with a rod of iron. Bar iron. See Wrought iron (below). Bog iron, bog ore; limonite. See Bog ore, under Bog. <chemistry> Cast iron, the purest form of iron commonly known in the arts, containing only about half of one per cent of carbon. It is made either directly from the ore, as in the Catalan forge or bloomery, or by purifying (puddling) cast iron in a reverberatory furnace or refinery. It is tough, malleable, and ductile. When formed into bars, it is called bar iron. Origin: OE. Iren, AS. Iren, isen, isern; akin to D. Ijzer, OS. Isarn, OHG. Isarn, isan, G. Eisen, Icel. Isarn, jarn, Sw. & Dan. Jern, and perh. To E.
