| 영문 | tetracycline | 한글 | 테트라사이클린 |
|---|---|---|---|
| 설명 | 항생제의 하나로서 그람양성과 그람음성세균에 모두 잘 들으며 세포벽에 작용하는 페니실린계열의 항생제가 잘 듣지 않는 세균에도 잘 들으나 부작용이 있고 내성이 증가하여 최근에는 특수한 몇가지 경우에만 사용된다. 작용메커니즘은 세균의 tRAN가 mRNA-ribosome complex에 접근하는 것을 막아 세균의 RNA 합성 및 단백질 합성을 억제함. 테트라사이클린에 대한 내성은 세균의 세포막이 변화하여 약이 세포내로 들어오지 못하게 하므로서 생긴다. |

|---|---|---|---|
| 설명 | 피부를 날카로운 바늘로 긁어 피부의 반응을 보는 검사로 피부 과민반응이나 알레르기를 알아보기 위한 검사이다. 바늘끝에 항원을 묻힌 뒤, 피부밑을 긁어 반응을 알아본다. 이때 항원이 아닌 대조물질(예를 들어 보통의 물)을 묻힌 바늘을 같이 반응하여 피부묘기증(dermographism) 단지 바늘의 긁힘만으로 알레르기 같은 반응을 일으키는 현상과 감별해야 한다. 난청, 청력소실(hearing loss) 청각이 저하 또는 상실된 상태. 원인과 정도는 여러 가지인데, 난청은 그 정도가 가장 심한 상태이다. 청각의 전도경로에 장애가 있을 때 난청이 일어나고, 그 병터가 외이도나 중이에 있는 것을 전음난청, 내이에 있는 것을 감음 난청이라 하여 구분한다. 또 병터의 자리를 명시하여 중이성 난청이나 미로성 난청 등으로 세분하기도 한다. |

|---|---|---|---|
| 설명 | 대변내에 있을 수 있는 잠혈(눈에 보이지 않는 출혈)유무를 검사하는 방법으로, 혈구내의 heme peroxidase에 의해 guaiac이 산화되는 반응을 이용하여 측정한다. 방법은 3일간에 걸쳐 한 변에서 2군데씩 채취하여 검사한다. 위양성 반응(거짓으로 혈액이 있다고 나타나는 반응)은 식물 과산화효소를 함유하고 있는 홍당무의 섭취나 혈구 성분을 함유하고 있는 고기 섭취 등에서 나타날 수 있으며, 위음성 반응(실제로 혈액은 있지만, 혈액이 없다고 나타나는 반응)은 환원력을 가지고 있는 비타민 C의 복용시 나타날 수 있다. 특히 위양성 반응이 매우 흔하다. |

| 설명 | 사고장애와 정서장애에 민감한 투사검사(projective test). 검은색과 몇가지 색으로 이루어진 잉크얼룩같은 도형이 그려진 10개의 카드를 이용한다. 피검자에게 카드를 보이고 본 것에 대해 말하도록 한다. 다음에는 얼룩의 어느 위치가 피검자가 말한 지각대상을 암시하는지 찾도록 한다. 피검자의 답변을 분석하면 그의 사고와 정서상태에 대한 정보를 얻을 수 있다. |

|---|---|
| tetracycline | <drug> Broad spectrum antibiotic that blocks binding of aminoacyl tRNA to the ribosomes of both gram-positive and gram-negative organisms (and those of organelles). Produced by Streptomyces aureofasciens. Other exaples include tetracycline, demeclocycline and doxycycline. (09 Oct 1997) |
| tetracycline 5a(11a)dehydrogenase | <enzyme> Catalyses the oxidation of 7-chloro-5a(11a)-dehydrotetracycline to 7-chlorotetracycline; uses nadp Registry number: EC 1.3.1.- (26 Jun 1999) |
| tetracycline resistance | Nonsusceptibility of a microbe (usually a bacterium) to the action of tetracycline, which binds to the 30s ribosomal subunit and prevents the normal binding of aminoacyl-trna. (12 Dec 1998) |
| ratio imaging fluorescence microscopy | <procedure> A method of measurement of intracellular pH or intracellular calcium levels, using a fluorescent probe molecule (see fura-2), in which the two different excitation wavelengths are used and the emitted light levels compared. If emission at one wavelength is sensitive to the intracellular ion level and emission at the other wavelength is not, then standardisation for intracellular probe concentration, efficiency of light collection, inactivation of probe and thickness of cytoplasm can all be performed automatically. (17 Dec 1997) |
| microscopy, fluorescence | Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilises antibodies that are labelled with fluorescent dye. (12 Dec 1998) |
| spectrometry, fluorescence | Measurement of the intensity and quality of fluorescence. (12 Dec 1998) |
| Eranko's fluorescence stain | <technique> Exposure of frozen sections to formaldehyde which produces a strong yellow-green fluorescence from cells containing norepinephrine. (05 Mar 2000) |
| fluorescence | <chemistry, physics> The emission of one or more photons by a molecule or atom activated by the absorption of a quantum of electro magnetic radiation. Typically the emission, that is of longer wavelength than the excitatory radiation, occurs within 10exp 8 seconds: phosphorescence is a phenomenon with a longer or much longer delay in re radiation. Note that rays, X-rays, UV, visible light and IR radiations may all stimulate fluorescence. (25 Jun 1999) |
| fluorescence-activated cell sorter | <technique> Flow cytometry is an emerging technique which holds great promise for the separation, classification and quantitation of blood cells and antibodies which affect blood cells. Complex computerised instruments are used to pass a monocellular stream of cells, platelets or other microscopic particulate elements through a beam of laser light. The cells are categorised first by size and then computer analysed to sort the mixture of cellular elements into cell type by size. Cells are labelled with fluorescent dye and then passed, in suspending medium, through a narrow dropping nozzle so that each cell is in a small droplet. A laser based detector system is used to excite fluorescence and droplets with positively fluorescent cells are given an electric charge. Charged and uncharged droplets are separated as they fall between charged plates and so collect in different tubes. The machine can be used either as an analytical tool, counting the number of labelled cells in a population or to separate the cells for subsequent growth of the selected population. Further sophistication can be built into the system by using a second laser system at right angles to the first to look at a second fluorescent label or to gauge cell size on the basis of light scatter. The great strength of the system is that it looks at large numbers of individual cells and makes possible the separation of populations with, for example: particular surface properties. Tabulation of counted data in conjunction with size analysis enables determination of relative percentages of each specific cellular subset for which monoclonal antibody conjugates are utilised, even when the size of the cell is identical to other subset species. Flow cytometry is a slightly imprecise but common term for the use of the Fluorescence-activated Cell Sorter (FACS). (01 Dec 1998) |
| fluorescence-activated cell sorting | <technique> A technique for separating and sorting cells marked with a fluorescent label based on how much they fluoresce at a particular wavelength. (12 Jan 1998) |
| fluorescence energy transfer | <technique> Transfer of energy from one fluorochrome to another. The emission wavelength of the fluorochrome excited by the incident light must approximately match the excitation wavelength of the second fluorochrome. If light at the second emission wavelength is detected, it implies that the two fluorochromes were physically within a few nanometres. Used as a technique to probe protein or cell interactions. (25 Jun 1999) |
| fluorescence immunoassay | <technique> A sensitive technique which uses fluorescein, a fluorescent molecule, to measure the antigen or antibody concentration in a solution. (09 Oct 1997) |
| fluorescence in situ hybridization | <molecular biology, technique> A type of in situ hybridization in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei. Acronym: FISH (25 Jun 1999) |
| fluorescence microscope | <instrument, microscopy> A microscope illuminated by ultraviolet or blue light so that the object may re-radiate light of longer wavelengths. To protect the eyes, a W-absorbing filter should be provided if not built into the fluorescence microscope. (05 Aug 1998) |
