| 설명 | 미생물을 염색하는 방법 중의 하나. 1884년 덴마크의 의사 H.C.J. 그람(1853~ 1938)이 고안한 특수 염색법이다. 이 염색법을 사용하면 미생물은 양성균과 음성균의 2무리로 크게 나뉜다. 염색법은 균을 유리면에 바르고 가열 고정한다. 젠시안바이오렛, 크리스탈 바이오렛, 메틸바이오렛 등 파라로즈 아닐린계 색소의 어느 하나를 사용하여 우선 염색하고 이어서 루골액을 작용시킨 뒤, 에탄올 또는 아세톤으로 탈색한다. 이때 탈색되지 않고 보라색을 타나내는 것을 그람양성균이라 부르며, 포도알균-폐렴알균-사슬알균 등이 대표적인 예이다. 탈색되면 그람음성균이라 부르며, 대장균-녹농균 등이 있다. 최후에 사프라닌, 푹신 등 적색계의 색소액으로 후염색을 한다. 미생물의 감별에 중요한 염색법이며 염색성의 차이는 영양요구성, 화학요법제(항생물질 등)에 대한 감수성의 차이와도 관련되는 점이 많으므로 사용약제의 선택시에도 중요한 역할을 한다. 그람양성균과 음성균의 차이는 세균벽의 구조에 있는데, 양성균은 세포막의 바깥쪽 펩티드글리칸이라는 당단백질층의 두께가 20~80nm나 되고, 그램음성균의 펩티드글리칸 층은 2~3nm로 얇고, 다시 바깥쪽에 외막이라 부르는 층이 있다. |

| Loeffler's stain | <technique> A stain for flagella; the specimen is treated with a mixture of ferrous sulfate, tannic acid, and alcoholic fuchsin, then stained with aniline-water fuchsin or gentian violet made alkaline with sodium hydroxide solution. (05 Mar 2000) |

| caustic | <chemistry> An escharotic or corrosive agent. Synonym: cauterant. Origin: L. Causticus, Gr. Kaustikos (18 Nov 1997) |
| caustic alkali | A highly ionised (in solution) alkali; e.g., NaOH. (05 Mar 2000) |
| caustic potash | KOH;a strong, penetrating caustic. Synonym: caustic potash. (05 Mar 2000) |
| caustic soda | <chemical> A highly caustic substance that is used to neutralise acids and make sodium salts. Pharmacological action: caustics, pharmaceutic aid. Chemical name: Sodium hydroxide (Na(OH)) (12 Dec 1998) |
| lunar caustic | Silver nitrate mixed with silver chloride and allowed to dry. Usually applied to the ends of small wooden applicator sticks or made available as pencils. These are used after wetting as a caustic chemical for the removal of warts. Synonym: fused silver nitrate, lunar caustic. (05 Mar 2000) |
| Klebs-Loeffler bacillus | <bacteria> A species of gram-positive, asporogenous bacteria in which three cultural types are recognised. These types (gravis, intermedius, and mitis) were originally given in accordance with the clinical severity of the cases from which the different strains were most frequently isolated. This species is the causative agent of diphtheria. (12 Dec 1998) |
| Loeffler, Friedrich | <person> German bacteriologist and surgeon, 1852-1915. See: Loeffler's bacillus, Loeffler's blood culture medium, Loeffler's stain, Loeffler's caustic stain, Loeffler's methylene blue, Klebs-Loeffler bacillus. (05 Mar 2000) |
| loeffler pneumonia | <radiology> Idiopathic, local, nonsegmental areas of TRANSIENT consolidation, most dense at periphery, reversed oedema pattern, peripheral eosinophilia, benign course differentiate from: chronic eosinophilic pneumonia, mucoid impaction (with or without ABPA) (12 Dec 1998) |
| Loeffler's bacillus | <bacteria> A species of gram-positive, asporogenous bacteria in which three cultural types are recognised. These types (gravis, intermedius, and mitis) were originally given in accordance with the clinical severity of the cases from which the different strains were most frequently isolated. This species is the causative agent of diphtheria. (12 Dec 1998) |
| Loeffler's blood culture medium | A culture medium consisting of beef blood serum, sheep blood serum, and beef bouillon containing peptone, glucose, and sodium chloride; used for the isolation of Corynebacterium diphtheriae. (05 Mar 2000) |
| Loeffler's methylene blue | A stain for diphtheria organisms that contains methylene blue in dilute ethanol plus a slight amount of potassium hydroxide; dye solution gives best results when aged to a polychrome state. (05 Mar 2000) |
| Loeffler's syndrome | <syndrome> A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count (CBC) shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| Abbott's stain | <technique> Spores are stained blue with alkaline methylene blue; bodies of the bacilli become pink with eosin counterstain. (05 Mar 2000) |
| aceto-orcein stain | <technique> A stain used for chromosomes in air-dried or squashed cytologic material. (05 Mar 2000) |
