| 영문 | enzyme | 한글 | 효소 |
|---|---|---|---|
| 설명 | 생물체 세포속에서 합성되고, 주로 세포내에서 진행되는 화학반응을 촉매하는 단백질로 시험관내에서도 같은 촉매작용을 한다. 이 효소는 인공적으로 만든 어떤 촉매제보다 그 특이성과 촉매작용이 탁월한 특별한 생체분자이다. 신진대사, 즉 세포내에서 일어나는 물질의 화학적 변환은 효소의 작용에 의해 매우 빠르고 원할하게 이루어진다. 이것은 효소의 촉매 효율이 높은 점과 효소의 기질 특이성 때문이다. 효소반응은 상온, 상압, 최적 pH 등 적절한 조건 아래에서 진행된다. 또 효소의 주체가 단백질이기 때문에 단백질을 변성시키는 열, 강산, 강알칼리, 유기용매 등에 의해 그 작용을 잃는다. 효소는 생체에 널리 분포하며, 복잡하고 다양한 대사반응을 촉매하기 때문에 종류도 많다. 앞서 말한 바와 같이 대부분의 효소는 세포내에 존재하지만, 혈액과 그외의 간질액에 들어 있기도 하고 소화효소류처럼 체외로 분비되는 것도 있다. |

| 영문 | enzyme-linked immunoabsorbent assay | 한글 | 효소면역측정법 |
|---|---|---|---|
| 설명 | 효소결합면역흡착제 검정법으로 번역되고 있다. 이 법은 항원(또는 항체)에 알칼리 포스파타아제 또는 페르옥시디아제 등의 산소를 결합시켜 두고 그 산소활성을 지표로 삼아 항원항체반응의 정도를 안 다음 여기에서 항원(또는 항체)의 양을 구하는 것이다. 이 법의 이점으로서 고감도, 조작의 간단함 및 방사선면역측정법처럼 방사성물질을 사용하지 않아도 된다는 점을 들 수 있다. 호르몬이나 면역글로불린의 정량법으로서 응용 되고 있으며 측정용 키트도 시판되고 이있다. |

| gas constant | R (symbol for the constant) = 8.314 × 107 ergs per degree Celsius per mole = 8.314 J K-1 mol-1 (joules per kelvin mole). (05 Mar 2000) |
|---|---|
| gas cyst | A cyst with gaseous instead of the ordinary liquid or pultaceous contents. (05 Mar 2000) |
| gas embolism | <physiology> A serious condition that results when air (in the form of bubbles) invades the blood vessels causing disruption of normal blood flow. (06 Aug 1998) |
| gas engine | A piston engine that uses gaseous fuel rather than gasoline. Fuel and air are mixed before they enter cylinders; ignition occurs with a spark. (05 Dec 1998) |
| gas gangrene | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| gas gangrene antitoxin | Antitoxin specific for the toxin of one or more species of Clostridium that cause gaseous gangrene and associated toxaemia, especially C. Perfringens C. Novyi, C. Histolyticum, and commercially available preparations are usually polyvalent, i.e., contain antitoxin for two or more species. Synonym: pentavalent gas gangrene antitoxin. (05 Mar 2000) |
| gas, intestinal | The complaint referred to as intestinal gas is a common one and the discomfort can be quite significant. Everyone has gas and eliminates it by burping or passing it through the rectum. In many instances people think they have too much gas when in reality they have normal amounts. most people produce 1 to 3 pints of intestinal gas in 24 hours and pass gas an average of 14 times a day. It is made up primarily of odourless vapors such as carbon dioxide, oxygen, nitrogen, hydrogen, and in some families, methane. The unpleasant odour is due to bacteria in the large intestine that release small amounts of gases containing sulfur. (12 Dec 1998) |
| gas-liquid chromatography | <technique> A chemistry lab technique, a type of column chromatography, used to separate the components of a mixed substance. The substance is held stationary by an inert solid coated with an inert liquid which is not likely to evaporate (i.e. Is nonvolatile), while a gas (called an eluant) flows past it bringing out the components one at a time. (09 Oct 1997) |
| gas peritonitis | Inflammation of the peritoneum accompanied by an intraperitoneal accumulation of gas. (05 Mar 2000) |
| gas phlegmon | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| gas retinopexy | A retinal detachment repair in which the retina is held in place by an expandable gas. Synonym: pneumatic retinopexy. (05 Mar 2000) |
| gas scavengers | Apparatus for removing exhaled or leaked anaesthetic gases or other volatile agents, thus reducing the exposure of operating room personnel to such agents, as well as preventing the buildup of potentially explosive mixtures in operating rooms or laboratories. (12 Dec 1998) |
| gas shift process | A process in which carbon monoxide and hydrogen react in the presence of a catalyst to form methane and water. (05 Dec 1998) |
| gas thermometer | A thermometer filled with dry air or a gas, the expansion or increased pressure of which indicates the degree of heat; used to measure high temperatures. (05 Mar 2000) |
| gas turbine | (combustion turbine) A turbine that converts the energy of hot compressed gases (produced by burning fuel in compressed air) into mechanical power. Often fired by natural gas or fuel oil. (05 Dec 1998) |
