| 영문 | acetic acid | 한글 | 아세트산, 초산 |
|---|---|---|---|
| 설명 | 분자식은 C2H4O2, 분자량 60.05의 저급 지방산이다. CH3COOH의 구조식을 가진 무색액체로 16.7℃에서 녹고 118.0℃에서 끓는다. 식초의 신맛을 내는 것이고, 농축된 것을 빙초산이라 한다. 상온에서는 액체이며 수용액은 약산성이다. 생체내에서는 일반적으로 아세틸 CoA로 존재하며 아세틸기의 공급원이 되는 외에 지방산이나 스테로이드 등의 생성재료로 중요하다. 아세틸 CoA로부터는 케톤체가 합성되며 조직의 에너지원이 된다. |

| 영문 | uric acid | 한글 | 요산 |
|---|---|---|---|
| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

|---|---|---|---|
| 설명 | 아닐린 색소에 염색되기 힘드나 일단 염색되면 강산으로 처리하여도 탈색되지 아니하는 세균을 통틀어 이르는 말. 결해균, 나병균 따위가 있다. |

| 영문 | acid-fast staining | 한글 | 항산염색 |
|---|---|---|---|
| 설명 | 항산성성질(좀처럼 염색이 되지 않으나 한번 염색이 되면 산성용액에 의해서 탈색이 되지 않는 성질)을 가진 균(예를 들면 결핵균 등)의 검출에 이용되는 염색방법. 방법에는 Ziehl-Neelson법과 Kinyoun법 등이 있다. |

| Bowman's probe | A double-ended probe for the lacrimal duct. (05 Mar 2000) |
| radioactive probe | A nucleic acid fragment, labelled by a radioisotope, biotin, etc., that is complementary to a sequence in another nucleic acid (fragment) and that will, by hydrogen binding to the latter, locate or identify it and be detected; a diagnostic technique based on the fact that every species of microbe possesses some unique nucleic acid sequences which differentiate it from all others, and thus can be used as identifying markers or "fingerprints." (05 Mar 2000) |
| magnetic probe | <radiobiology> A conducting coil (sometimes insulated and inserted into the plasma) will have an induced voltage due to changes in the magnetic flux through the coil, and can therefore be used to measure changes in magnetic field strength. Small coils used to measure the local field strength are known as probes. (Other plasma diagnostics using this effect are the Rogowski coil, the voltage loop, and the diamagnetic loop.) Magnetic probes placed outside a toroidal plasma which are used to measure the poloidal magnetic field are also called Mirnov coils. (09 Oct 1997) |
| gene probe | A biomolecule that islabelled with radioactive isotopes or with a fluorescent marker that selectively binds to a specific gene so it can be isolated or identified. (09 Oct 1997) |
| vertebrated probe | A probe made up of a series of short sections hinged together for flexibility in penetrating convoluted tracts. (05 Mar 2000) |
| viral probe | A nucleic acid fragment, labelled by a radioisotope, biotin, etc., that is complementary to a sequence in another nucleic acid (fragment) and that will, by hydrogen binding to the latter, locate or identify it and be detected; a diagnostic technique based on the fact that every species of microbe possesses some unique nucleic acid sequences which differentiate it from all others, and thus can be used as identifying markers or "fingerprints." (05 Mar 2000) |
| periodontal probe | A calibrated instrument used to measure the depth and topography of periodontal pockets. (05 Mar 2000) |
| molecular probe techniques | The use of devices which use detector molecules to detect, investigate, or analyze other molecules, macromolecules, molecular aggregates, or organisms. (12 Dec 1998) |
| multi-locus probe | A probe that hybridizes to anumber of different sites in the genome of an organism. (09 Oct 1997) |
| probe | <molecular biology> General term for a piece of DNA or RNA corresponding to a gene or sequence of interest, that has been labelled either radioactively or with some other detectable molecule, such as biotin, digoxygenin or fluorescein. As stretches of DNA or RNA with complementary sequences will (hybridise), a probe will label viral plaques, bacterial colonies or bands on a gel that contain the gene of interest. See: Northern blots, Southern blots. (18 Nov 1997) |
| probe patency | (of foramen ovale), a term introduced by B.M. Patten to cover incomplete fibrous adhesion of an adequate valvula foraminis ovalis in the postnatal closure of the foramen ovale. (05 Mar 2000) |
| probe-pointed | <surgery> Having a blunt or button-shaped extremity; said of cutting instruments. Source: Websters Dictionary (01 Mar 1998) |
| probe syringe | A syringe with an olive-shaped tip, used in treatment of diseases of the lacrimal passages. (05 Mar 2000) |
| Scanning Probe Microscopy | <technique> Initially called Atomic Force Microscopy, this technique is now more typically termed Scanning Force Microscopy or Scanning Probe Microscopy. This instrument is essentially an extremely high resolution profilometre. A sharp tip, typically fabricated from silicon nitride, is scanned across the surface of a sample at a constant force by three piezoelectric ceramics. The piezoelectric ceramics are computer controlled via a feedback loop which monitors the position of the tip by means of an optical lever. (A laser is focused on the top of the tip support and the beam reflected into a position sensitive detector). The changes in height of the tip are used to form an image as the tip is scanned across the sample. Acronym: SPM (26 Mar 1998) |
