| 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. |

| Weigert-Gram stain | <technique> A stain for bacteria in tissues in which sections are stained in alum-haematoxylin, then in eosin, aniline methyl violet, and Lugol's solution. (05 Mar 2000) |
|---|---|
| Weigert's iron haematoxylin stain | <technique> A nuclear staining solution containing haematoxylin, ferric chloride, and hydrochloric acid; useful in combination with von Gieson's stain, especially for demonstrating connective tissue elements or Entamoeba histolytica in sections. (05 Mar 2000) |
| Weigert's stain | <technique> 1. For actinomyces, a staining method using immersion in a dark red orsellin solution in alcohol, then staining in crystal-violet solution. See: iron haematoxylin. 2. For elastin, a staining solution of fuchsin, resorcin, and ferric chloride; elastic fibres stain blue-black. 3. For fibrin, a staining method using solutions of aniline-crystal violet and iodine-potassium iodide, then decolorizing in aniline oil and xylol; the fibrin is stained dark blue. 4. For myelin, a staining method using ferric chloride and haematoxylin; myelin stains deep blue, degenerated portions a light yellowish colour. 5. For neuroglia, a complicated process in which the final treatment is like that for staining fibrin; neuroglia and nuclei stain blue. 6. For reticulum, a silver impregnation technique in which reticulum appears as black, well-defined fibres without beading and with a relatively clear background. (05 Mar 2000) |
| actinomyces | <microbiology> A genus of gram-positive, rod-shaped bacteria whose organisms are nonmotile. Filaments that may be present in certain species are either straight or wavy and may have swollen or clubbed heads. (12 Dec 1998) |
| Actinomyces bovis | A species of bacteria causing actinomycosis in cattle; infection in humans is not established; it is the type species of its genus. (05 Mar 2000) |
| Actinomyces israelii | A species of bacteria causing human actinomycosis and, occasionally, infections in cattle. (05 Mar 2000) |
| Actinomyces naeslundii | A species whose natural habitat is the oral cavity; human infections have been reported, and it produces periodontal destruction in some species of animals. (05 Mar 2000) |
| Actinomyces odontolyticus | A species whose normal habitat is the human oral cavity; it has been isolated from deep dental caries. (05 Mar 2000) |
| Actinomyces pyogenes | <bacteria> A species of corynebacterium isolated from abscesses of warm-blooded animals. (12 Dec 1998) |
| actinomyces viscosus | <microbiology> A species of actinomyces found in the oral cavity of man and hamsters. It has been isolated from actinomycotic lesions in swine, cats, and dogs and has been identified as a causative agent of animal diseases. (12 Dec 1998) |
| Weigert, Carl | <person> German pathologist, 1845-1904. See: Weigert's law, Weigert's iodine solution. See entries under stain. (05 Mar 2000) |
| weigert-meyer rule | <radiology> Applies to duplex collecting systems, upper-pole ureter, obstruction most likely to be hydronephrosis, inserts more inferiorly and medially in bladder, may insert into urethra, vagina, etc., males not incontinent: insertion above ext. Sphincter, associated with ureterocele, lower-pole ureter, reflux most likely to be pyelonephritis see also: drooping lily sign (12 Dec 1998) |
| Weigert's iodine solution | An iodine-potassium iodide mixture used as a reagent to alter crystal and methyl violet so that they are retained by certain bacteria and fungi. (05 Mar 2000) |
| Weigert's law | The loss or destruction of a part or element in the organic world is likely to result in compensatory replacement and overproduction of tissue during the process of regeneration or repair (or both), as in the formation of callus when a fractured bone heals. Synonym: overproduction theory. (05 Mar 2000) |
| Abbott's stain | <technique> Spores are stained blue with alkaline methylene blue; bodies of the bacilli become pink with eosin counterstain. (05 Mar 2000) |
