|---|---|---|---|
| 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. |

| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| vasopressin level | This test measures the amount of ADH in the serum. It is used to detect disorders that may affect the level of ADH in the serum. Normal values are: 0 to 4.7 pg/ml. Elevated ADH levels can indicate a CNS infection, fluid imbalance, CNS tumour, SIADH or acute porphyria. Low levels can indicate: diabetes insipidus or damage to the pituitary gland. (27 Sep 1997) |
|---|---|
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| mean sea level | <marine biology> A tidal datum: the arithmetic mean of hourly water elevations observed over a specific 19-year cycle. Points on land can be referenced to a mean sea level, in which case the datum assumes zero elevation. (09 Oct 1997) |
| gray level also gray value | <microscopy> The brightness of pixels in a digitised video image, commonly expressed in integers ranging from 0 (black) to 255 (white) for an 8-bit digital signal. (05 Aug 1998) |
| gray level histogram | <microscopy> In digital image processing, a histogram that depicts the number of pixels at each gray value. The histogram can be used to measure the areas that have given ranges of gray values or to adjust image contrast by histogram stretching or equalisation. See: Image histogram. (05 Aug 1998) |
| Clark's level | The level of invasion of primary malignant melanoma of the skin; limited to the epidermis, I; into the underlying papillary dermis, II; to the junction of the papillary and reticular dermis, III; into the reticular dermis, IV; into the subcutaneous fat, V. The prognosis is worse with each successive deeper level of invasion. (05 Mar 2000) |
| cohb level | A blood test which is performed on an arterial specimen and is a measurement of the amount of carbon monoxide which is present and bound to haemoglobin. This is an important test to diagnosis carbon monoxide toxicity (smoke inhalation). Normal carboxyhaemoglobin may be from 3% to as high as 12% in heavy smokers. Symptoms of carbon monoxide poisoning begin at about 20% carboxyhaemoglobin. (27 Sep 1997) |
| white level | <microscopy> Also reference white level. The IEEE scale, or voltage level, of the video picture signal that corresponds to a specified maximum limit for white peaks. (05 Aug 1998) |
| window level | The CT number setting in Hounsfield units of the midpoint of the window width, which is the gray scale of the image; a typical window level for imaging the lungs if -500; for the abdomen, 0. (05 Mar 2000) |
| hearing level | The measure of the status of hearing as read directly on the hearing loss scale of an audiometer; described in decibels as a deviation from a standard value for zero on the audiometer. (05 Mar 2000) |
| serum iron level | A test that measures the amount of iron (Fe ++) in the blood. The test is performed when iron deficiency is suspected. Normal serum iron is 60 to 170 mcg/dl. Increased levels may be seen in the following: haemochromatosis, haemolysis, haemolytic anaemia, hepatitis, liver necrosis, haemosiderosis, iron poisoning and lead toxicity. Lower than normal levels are seen in chronic GI blood loss, iron deficiency anaemia, insufficient dietary iron, malabsorption, chronic heavy menstrual bleeding, nephrosis and late pregnancy. (27 Sep 1997) |
| sound pressure level | A measure of sound energy relative to 0.0002 dynes/cm2, expressed in decibels. (05 Mar 2000) |
| substrate-level phosphorylation | Synthesis of high-energy phosphate bonds through reaction of inorganic phosphate with an activated (usually) organic substrate. (09 Oct 1997) |
| no-observed-adverse-effect level | The highest dosage administered that does not produce toxic effects. The noael will depend on how closely dosages are spaced (lowest-observed-adverse-effect level and no-observed-effect level) and the number of animals examined. The ultimate objective is usually to determine not the "safe" dosage in laboratory animals but the "safe" dosage for humans. Therefore, the extrapolation most often required of toxicologists is from high-dosage studies in laboratory animals to low doses in humans. (casarett and doull's toxicology: the basic science of poisons, 4th ed) (12 Dec 1998) |
| organic level | The amount of organic matter prescribed to be left after logging. (05 Dec 1998) |
