| 영문 | MVP(=mitral valve prolapse) | 한글 | 승모판 탈출증 |
|---|---|---|---|
| 설명 | 승모판이 좌심실운동시 제대로 닫혀주지 못하고 빠져나오는 상태로서 주로 젊은 여성에게서 발견된다. 다른 말로 청진상의 소견을 따서 “clickmurmur syndrome”이라고도 하고 혹은 처음 발견한 의사의 이름을 따서 “Barlow's syndrome”이라고도 한다. 개 정상적인 삶을 누리게 되나, 일부에서 심내막염(심장내막의 염증: endocarditis)의 위험이 증가하므로 치과적 시술시 예방적 항생제가 필요하기도 하다. |

| 영문 | mitral valve | 한글 | 승모판막 |
|---|---|---|---|
| 설명 | 좌심실과 좌심방사이에 존재하는 판막. 2개의 막으로 나누어져 있으며, 밑으로 심근과 연결되어 있다. |

| 영문 | mitral stenosis | 한글 | 승모판막 협착증 |
|---|---|---|---|
| 설명 | 승모판막(좌심방과 좌심실사이에 존재하는 판막)이 좁아져 있는 병적인 상태를 말함. 정상적으로 승모판사이의 공간면적은 4~6cm정도이며, 이 면적이 2.5cm이하가 되면 증상이 나타난다. 그리고 1~2cm이하가 되면 수술을 고려해야 한다. 운동성 호흡곤란이 주증상이며, 심장청진상 심잡음이 들린다. 증상과 협착의 정도에 따라 다르나, 대개 수술을 고려해야 하며, 수술은 판막대치술, 판막성형술 등이 있고, 판막대치술에도, 조직판막을 이용하는 방법과 기계판막을 이용하는 방법 2가지로 나눌 수 있다. |

| magnetic field gradient | In magnetic resonance imaging, a magnetic field that varies with location, superimposed on the uniform field of the magnet, to alter the resonant frequency of nuclei and allow recovery of their spatial position. Synonym: field gradient. (05 Mar 2000) |
| ventricular gradient | The algebraic sum of (i.e., the net electrical difference between) the area enclosed within the QRS complex and that within the T wave in the electrocardiogram. (05 Mar 2000) |
| voltage gradient | <physiology> Literally, the electric field in a region, defined as the potential difference between two points divided by the distance between them. Used more loosely, the potential difference across a plasma membrane. (18 Nov 1997) |
| centrifugation, density gradient | Separation of particles according to density by employing a gradient of varying densities. at equilibrium each particle settles in the gradient at a point equal to its density. (12 Dec 1998) |
| cesium chloride gradient centrifugation | A type of density gradient centrifugation, a lab technique used to separate or purify nucleic acids. It involves putting cesium chloride and the nucleic acids into a centrifuge to be spun for hours or days. The cesium chloride forms a density gradient (highly dense at the bottom, thinnest at the top), and the different nucleic acids separate along the gradient according to their buoyancies in different densities. (09 Oct 1997) |
| gradient | <physics> Mathematical term for the operator which determines the magnitude and direction of the greatest rate-of-change of a given function with position. Similarly used to describe such a rate-of-change. For instance, at a given point on a hill, the slope of the hill in the steepest uphill direction is the gradient of the altitude function for the hill. (09 Oct 1997) |
| gradient elution | Elution in column chromatography in which a changing pH or ionic strength is used to separate substances. (05 Mar 2000) |
| gradient encoding | In magnetic resonance imaging, the technique of inducing a gradient in the magnetic field in the Y-axis to induce phase differences with location. Synonym: gradient encoding. (05 Mar 2000) |
| gradient perception | <cell biology> Problem faced by a cell that is to respond directionally to a gradient of, for example: a diffusible attractant chemical. In a spatial mechanism the cell would compare receptor occupancy at different sites on the cell surface, a temporal mechanism would involve comparison of concentrations at different times, the cell moving randomly between readings. In pseudospatial sensing, the cell would detect the gradient as a consequence of positive feedback to protrusive activity if receptor occupancy increased with time as the protrusion moved up gradient. Few cell types have been unambiguously shown to detect gradients. (18 Nov 1997) |
| concentration gradient | <chemistry> A column of liquid in which the density varies continually with position, usually as a consequence of variation of concentration of a solute. Such gradients may be established by progressive mixing of solutions of different density as for example: sucrose gradients) or by centrifuge induced redistribution of solute (as for caesium chloride gradients). Density gradients are widely used for centrifugal and gravity induced separations of cells, organelles and macromolecules. The separations may exploit density differences between particles or primarily differences in size, in which latter case the function of the gradient is chiefly to stabilise the liquid column against mixing. (12 Jan 1998) |
| critical gradient | <botany> The maximum stable inclination of an unsupported slope under the most adverse conditions that it will likely experience, as determined by current engineering technology. (09 Oct 1997) |
| pseudospatial gradient sensing | <cell biology> Mechanism for sensing a gradient of a diffusible chemical in which the cell sends protrusions out at random, up gradient protrusions are stabilised by positive feedback (because receptor occupancy is rising with time) and others are transitory because of adaptation. Possibly the mechanism by which neutrophils sense chemotactic gradients. (18 Nov 1997) |
