| 영문 | pulse pressure | 한글 | 맥박압 |
|---|---|---|---|
| 설명 | 수축기 혈압과 확장기 혈압의 차이. mmHg로 표시한다. 심장의 수축력, 동맥 내 혈류량, 동맥벽의 긴장도에 영향을 받는다. 정상치는 수축기 혈압의 1/3, 또는 확장기 혈압의 1/2이다. 60mmHg이상을 대맥이라고 하며, 대동맥판막 폐쇄부족증, 갑상샘항진증, 동맥경화증, 혈압이 상승할 때 심장비대, 고열 등에서 볼 수 있다. 20mmHg 이하를 소맥이라고 하며, 급성 심근경색에 의한 좌심실 수축력 저하, 대동맥판막 협착등에서 볼 수 있다. 한편 맥압의 1/3에 확장기 혈압을 더한 것을 평균혈압이라고 한다. |

| 영문 | osmotic pressure | 한글 | 삼투압 |
|---|---|---|---|
| 설명 | 삼투라는 현상은 일정 크기 이하의 물질은 통과시키고 그 이상의 크기를 가진 물질은 통과 시키지 못하게 하는 막(반투막)을 사이에 두고 양쪽에 그 막을 투과하지 못하는 물질의 농도가 차이가 날 때 발생하는 것으로 막을 통과할 수 있는 물질이 막 양쪽의 통과 할 수 없는 물질의 농도를 같게 하는 방향으로 움직이는 것을 말한다. |

| 영문 | systolic pressure | 한글 | 수축기압 |
|---|---|---|---|
| 설명 | 심활동력, 동맥벽의 탄력성, 혈액량, 혈액의 점성 등에 의하여 결정되는 혈액의 동맥벽에 미치는 압력으로서, 최고혈압은 왼심실로부터 박출이 끝나기 직전에 생기는 압을 말하고 최대 혈압 또는 수축기혈압이라 부른다. 최소혈압은 왼심실의 확장이 끝나는 시기에 생기는 혈압을 말하며 최소혈압 또는 확장기혈압이라고 부른다. 평균혈압은 동맥내압의 평균치를 말하며, 기초혈압은 절대안정 상태에서 측정한 혈압을 말한다. |

| 영문 | blood pressure | 한글 | 혈압 |
|---|---|---|---|
| 설명 | 혈압이란 혈관에 걸리는 압력을 말하는 것으로 대개 특별한 설명이 없으면 동맥의 압력을 말한다. 혈압에는 수축기혈압(systolic blood pressure)과 이완기혈압(diastolic blood pressure)이 있다. 수축기혈압이란 심장이 수축할 경우에 동맥에 걸리는 압력을 말하고, 이완기 혈압이란 심장이 이완할 경우에 동맥에 걸리는 압력을 말한다. 당연히 수축기 혈압이 이완기 혈압보다 높다. 혈압을 말할 때에 예를 들어 120/80mmHg이라고 적는 것의 앞의 것은 수축기 혈압을 의미하고 뒤에 적는 80은 이완기 혈압을 의미한다. |

| atrioventricular gradient | The diastolic pressure difference between the atrium and ventricle. (05 Mar 2000) |
|---|---|
| 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) |
| mitral gradient | The diastolic pressure difference between the left atrium and left ventricle. (05 Mar 2000) |
| 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) |

| pressure gradient |
(In meteorology, also called barometric gradient.) The rate of decrease (gradient) of pressure in space at a fixed time. The term is sometimes loosely used to denote simply the magnitude of the gradient of the pressure field.
