| 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 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) |

| intermediate body of Flemming | <cell biology> Dense structure formed during cytokinesis at the cleavage furrow. It consists of remnants of spindle fibres and other amorphous material and disappears before cell division is completed. (18 Nov 1997) |
| Flemming's fixative | A mixture of chromic acid, osmic acid, and acetic acid that makes an excellent cytoplasmic and chromosomal fixative, especially when acetic acid is omitted; disadvantages are that it penetrates poorly, requires lengthy washing, and deterioriates rapidly. (05 Mar 2000) |

| triple | 1. Consisting of three united; multiplied by three; threefold; as, a triple knot; a triple tie. "By thy triple shape as thou art seen." (Dryden) 2. Three times repeated; treble. See Treble. 3. One of three; third. Triple crown, the crown, or tiara, of the pope. See Tiara.

Triple measure, a measure of tree beats of which first only is accented. <mathematics> Triple ratio, that time in which each measure is divided into three equal parts. Triple valve, in an automatic air brake for railroad cars, the valve under each car, by means of which the brake is controlled by a change of pressure in the air pipe leading from the locomotive.
