| 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. |

| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
|---|---|
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Gomori's methenamine-silver stain | <technique> Techniques for 1) argentaffin cells: a method using a methenamine-silver solution in combination with gold chloride, sodium thiosulphate, and safranin O; argentaffin granules appear brown-black against a green background; 2) urates: warm sections are treated directly with a hot methenamine-silver solution to produce a blackening of urates; 3) fungi: see Grocott-Gomori methenamine-silver stain; 4) melanin, which reduces silver nitrate. (05 Mar 2000) |
| Grocott-Gomori methenamine-silver stain | <technique> A modification of Gomori's methenamine-silver stain for fungi in which sections are pretreated with chromic acid before addition of the methenamine-silver solution and then counterstained with light green to demonstrate black-brown fungi against a pale green background. (05 Mar 2000) |
| silver-ammoniacal silver stain | <technique> A stain for the acid protein component of nucleolar regions which are active or which were transcriptionally active in the preceding interphase; uses silver nitrate, ammoniacal silver, and formalin. Synonym: Ag-AS stain. (05 Mar 2000) |
| methenamine-silver | A hexamethylenetetramine-silver complex prepared by adding silver nitrate to methenamine; a white precipitate appears in the solution which dissolves upon shaking and is stable under refrigeration; used in various histological and histochemical staining methods. See: Gomori's methenamine-silver stain. (05 Mar 2000) |
| Masson-Fontana ammoniacal silver stain | <technique> A stain used to demonstrate melanin and argentaffin granules. Synonym: Fontana-Masson silver stain. (05 Mar 2000) |
| Gomori's silver impregnation stain | <technique> A reliable method for reticulin, as an aid in the diagnosis of neoplasm and early cirrhosis of the liver; the staining solution employs silver nitrate, potassium hydroxide, and ammonia water carefully prepared to avoid having silver precipitate. (05 Mar 2000) |
| Warthin-Starry silver stain | <technique> A stain for spirochetes in which preparations are incubated in 1% silver nitrate solution followed by a developer. (05 Mar 2000) |
| silver protein stain | <technique> A silver proteinate complex used in staining nerve fibres, nerve endings, and flagellate protozoa; also used to demonstrate phagocytosis in living animals by the cells of the reticuloendothelial system. (05 Mar 2000) |
| silver stain | <technique> Any of a variety of stain's (e.g., Bielschowsky's, Gomori's silver, impregnation stain's) which employ alkaline silver nitrate solutions to stain connective tissue fibres (reticulin, collagen), calcium salt deposits, spirochaetes, neurological tissue, and nucleolar organiser regions. (05 Mar 2000) |
| Fontana-Masson silver stain | <technique> A stain used to demonstrate melanin and argentaffin granules. Synonym: Fontana-Masson silver stain. (05 Mar 2000) |
| methenamine | <chemical> An antibacterial agent most commonly used in the treatment of urinary tract infections. Its antibacterial action derives from the slow release of formaldehyde by hydrolysis at acidic pH. Pharmacological action: anti-infective agents, urinary. Chemical name: 1,3,5,7-Tetraazatricyclo(3.3.1.13,7)decane (12 Dec 1998) |
| methenamine hippurate | Hexamethylenetetramine hippurate;a urinary antiseptic. (05 Mar 2000) |
