|---|---|---|---|
| 설명 | 프로트롬빈은 간에서 합성되는 비타민 K 의존성 응고단백질의 하나이며, 프로트롬빈시간은 외인계 응고활성을 종합적으로 특정하는 검사의 하나이다. 피검혈장에 칼슘이온과 조직트롬보플라스틴(제III 응고인자)을 가해, 섬유소가 나타날 때까지의 시간으 측정한다. |

| repetition time | In magnetic resonance imaging, the time between repetitions of the pulse sequence. (05 Mar 2000) |
|---|---|
| rise time | The time required for a pulse or echo to rise from 10% to 90% of its peak amplitude. (05 Mar 2000) |
| P-H conduction time | See: atrioventricular conduction. (05 Mar 2000) |
| running time | The time during which an activity (e.g., chromatography development) occurs. (05 Mar 2000) |
| Russell's viper venom clotting time | A clotting time determination performed on citrated platelet-poor plasma using Russell's viper venom as an activating agent. This allows activation of factor X directly without the need for other coagulation factors and is used to confirm factor X defects. See: Stypven time test. (05 Mar 2000) |
| circulation time | The time taken for the blood to pass through a given circuit of the vascular system, e.g., the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system. (05 Mar 2000) |
| clot retraction time | The time required for a blood clot to separate from the tube wall and express serum, usually completed in 18 to 24 hours, but retarded or absent in persons with thrombocytopenic purpura. (05 Mar 2000) |
| clotting time | The time required for blood to coagulate; prolonged in haemophilia and in the presence of obstructive jaundice, some anaemias and leukaemias, and some of the infectious diseases. Synonym: clotting time. (05 Mar 2000) |
| coagulation time | The time required for blood to coagulate; prolonged in haemophilia and in the presence of obstructive jaundice, some anaemias and leukaemias, and some of the infectious diseases. Synonym: clotting time. (05 Mar 2000) |
| collision time | <radiobiology> Typical time which passes between two consecutive collision events for a given particle. Inverse of the collision frequency, equal to the mean free path divided by the particle's velocity. In plasmas, the (Coulomb) collision time decreases with increasing density, and increases with increasing temperature. (09 Oct 1997) |
| whole blood coagulation time | Measurement of the time required by whole blood to produce a visible clot. Factors that could influence the test are all but III, vii, and xiii. Activation may be by contact with the glass tube or exposure to diatomaceous earth. Delay of onset of coagulation may be achieved by use of nonwettable plastic or silicone-coated glass tubes. It is used for monitoring heparin therapy and as a bedside screening test for deficiencies in the intrinsic coagulation pathway. "activated coagulation time" is sometimes referred to as act. (12 Dec 1998) |
| confinement time | <radiobiology> There are several types. The general definition is tau = [total]/[loss per unit time], hence Tau_E = [total energy]/[energy loss per unit time]. Tau_[E, N,.] is the amount of time the plasma is contained (for example, by magnetic fields) before its [energy (E), particles (N or P)] leak / dissipate away. The different types are, in general, similar but not equal. (N.B., Tau_E is NOT electron confinement time!) (09 Oct 1997) |
| continuous time model | <epidemiology> A model in which the system changes continuously over time. Derivatives (e.g. DY/dt ) are the mathematical formalism for describing such continuous change. The differential equation which embodies a model provides the values of these derivatives at any particular time point; calculus or a computer can then be used to move the state of the model forwards in time. Continuous models have the advantage over discrete time models in that they are more amenable to algebraic manipulation, although they are slightly harder to implement on a computer. The same as a differential equation model. (05 Dec 1998) |
| half-time | The time, in a first-order chemical (or enzymic) reaction, for half of the substance (substrate) to be converted or to disappear. Compare: half-life. (05 Mar 2000) |
| prothrombin time | Measurement of clotting time of plasma recalcified in the presence of excess tissue thromboplastin. Factors measured are fibrinogen, prothrombin, and factors v, vii, and x. It is used for monitoring anticoagulant therapy with coumarins. (12 Dec 1998) |
