| 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. |

| balloon counter pulsation | A form of circulatory assistance in which a balloon inflates in the aorta during diastole to improve diastolic pressure and deflates during systole to reduce left ventricular after load. (05 Mar 2000) |
| Geiger-Muller counter | <instrument> An instrument for measuring radioactivity by counting the emission of radioactive particles. It consists of a metallic cylinder, negatively charged, in a tube containing a fine, positively charged wire at its centre; radiations produce ionization of the gas molecules between the cylinder and the wire and result in an electrical discharge independent of the energy of the impinging particle or ray. (05 Mar 2000) |
| colony counter | A device which counts the number of colonies on an agar plate (a solid growth medium). (09 Oct 1997) |
| well counter | A scintillation crystal shaped with a central hole to receive a small sample, plus associated detector and electronics. (05 Mar 2000) |
| whole-body counter | Shielding and instrumentation, usually involving more than one detector, designed to evaluate the total-body burden of various gamma-emitting nuclides. (05 Mar 2000) |
| Coulter counter | <apparatus> Particle counter used for bacteria or eukaryotic cells, works by detecting change in electrical conductance of a small aperture as fluid containing cells is drawn through (the cell, a nonconducting particle, alters the effective cross-section of the conductive channel). (18 Nov 1997) |
| counter- | Opposite, opposed, against. See: contra-. Origin: L. Contra, against (05 Mar 2000) |
| proportional counter | A Geiger-Muller counter operating in the voltage range and under conditions in which pulse height is proportional to the energy of the particles or rays being counted, thus making discrimination between particles or rays of different energies possible. (05 Mar 2000) |
| scintillation counter | An instrument used for the detection of radioactivity; the radiation is absorbed by a scintillator (a crystal or a compound, such as POPOP, in solution) which results in minute flashes of light that are detected by a photocathode. The resultant electron emission is amplified by a photomultiplier and an amplifier. Synonym: scintillometer, spinthariscope. (05 Mar 2000) |
| drug, over-the-counter | Drug for which a prescription is not needed. (12 Dec 1998) |
| electronic cell counter | <apparatus, haematology> An automatic blood cell counter in which cells passing through an aperture alter resistance and are counted as voltage pulses, or in which cells passing through a flow cell deflect light. Some types of counter are capable of multiple simultaneous measurements on each blood sample; e.g., leukocyte count, red cell count, haemoglobin, haematocrit, and red cell indices. (21 Jun 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) |
| aceto-orcein stain | <technique> A stain used for chromosomes in air-dried or squashed cytologic material. (05 Mar 2000) |
| acid-fast stain | <technique> A staining technique used to determine the cell wall property of a microorganism. After stained with dye such as hot carbolfuschin, an acid-fast organism, (for example Mycobacterium species) will retain the colour in its cell wall after being washed with acid-alcohol.
