| 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. |

| Mallory's trichrome stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |
|---|
| picro-Mallory trichrome stain | <technique> A modification of Mallory's trichrome stain that involves the addition of picric acid. (05 Mar 2000) |
|---|---|
| Masson's trichrome stain | <technique> Original composition for multicolored tissue preparations included Ponceau de xylidine, acid fuchsin, iron alum haematoxylin, and either aniline blue or fast green FCF; chromatin stains black, cytoplasm is in shades of red, granules of eosinophils and mast cells are deep red, erythrocytes are black, elastic fibres are red, and collagen fibres and mucus are dark blue (aniline blue) or green (fast green FCF); modifications substitute other dyes, such as Biebrich scarlet red and wool green stain. (05 Mar 2000) |
| Gomori's one-step trichrome stain | <technique> A connective tissue stain that uses haematoxylin and a dye mixture containing chromotrope 2R and light green or aniline blue; muscle fibres appear red, collagen is green (or blue if aniline blue is used), and nuclei are blue to black. (05 Mar 2000) |
| MSB trichrome stain | <technique> A stain for fibrin using martius yellow, brilliant crystal scarlet 6R, and soluble blue; fibrin is selectively stained red and connective tissue appears blue. (05 Mar 2000) |
| trichrome stain | <technique> Staining combinations which usually contain three dyes of contrasting colours selected to stain connective tissue, muscle, cytoplasm, and nuclei in bright colours; generally, tissue sections are first dyed in iron haematoxylin before being treated with the other dyes. (05 Mar 2000) |
| Mallory's aniline blue stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |
| Mallory's collagen stain | <technique> One of a number of staining methods using phosphomolybdic or phosphotungstic acid with an acid stain, such as aniline blue, or with haematoxylin for connective tissue staining. (05 Mar 2000) |
| Mallory's iodine stain | <technique> Amyloid appears red-brown after Gram's iodine, then violet and blue after flooding with dilute sulfuric acid. (05 Mar 2000) |
| Mallory's phloxine stain | <technique> A technique based on retention of phloxine by hyaline after overstaining and then decolorizing with lithium carbonate, used in combination with alum haematoxylin to give nuclear staining; hyaline appears red, older hyaline is pink to colourless, amyloid is pale pink, and nuclei are blue-black. (05 Mar 2000) |
| Mallory's phosphotungstic acid haematoxylin stain | A stain with broad application in cytology and histology; nuclei, mitochrondria, fibrin, neuroglial fibrils, and cross-striations of skeletal and cardiac muscle stain blue; cartilage ground substance, bone reticulum, and elastin appear in shades of yellow-orange and brownish red; also useful for demonstrating abnormal or diseased astrocytes, often in combination with periodic acid-Schiff stain and Luxol fast blue. Synonym: Mallory's phosphotungstic acid haematoxylin stain. (05 Mar 2000) |
| Mallory's stain | <technique> For actinomyces, a stain using alum haematoxylin, followed by eosin; immersion in Ehrlich's aniline crystal violet stain, and Weigert's iodine solution; mycelia stain blue and clubs stain red. For haemofuchsin, sections are stained sequentially in alum haematoxylin and basic fuchsin; the lipofuchsin-like pigment and ceroid stain bright red, nuclei stain blue, while melanin and haemosiderin appear unstained in their natural browns. (05 Mar 2000) |
| Mallory's triple stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |
| Mallory bodies | Large, poorly defined accumulations of eosinophilic material in the cytoplasm of damaged hepatic cells in certain forms of cirrhosis and marked fatty change especially due to alcoholism. Synonym: alcoholic hyalin, alcoholic hyaline bodies. (05 Mar 2000) |
