| 영문 | complement fixation reaction | 한글 | 보체결합 반응, 도움체결합반응 |
|---|---|---|---|
| 설명 | 항체와의 반응에 있어서 보체와 결합하는 항체를 검사하는 방법으로, 이 반응은 최초에 기지항원, 피검혈청 및 보체를 혼합한다. 제2단계에서는 적혈구와 이것에 대응하는 용혈소의 혼합액을 가한다. 본 반응후 용혈이 일어나지 않으면 본체는 항원항체결합물에 결합한 것이 되어 양성이 되지만, 용혈이 일어난 경우 보체는 결합하지 않아 소비되지 않기 때문에 음성이 된다. 본 반응은 기지혈청을 써서 항원검출에 응용할 수 있으며, 마이코플라스마, 리케챠, 클라미디아, 바이러스, 매독 등의 진단에 쓰인다. |

| 영문 | graft versus host reaction | 한글 | 이식편대 숙주반응 |
|---|---|---|---|
| 설명 | 면역이란 자신의 것과 자신의 것이 아닌 것을 구분해서 자신의 것이 아닌 것을 공격하여 생물학적 활성을 없애거나 제거하는 것이다. 이 면역은 주로 혈액에 있는 세포에 의해서 이루어진다. 특히 림프구는 이 면역에 중추적인 역할을 하는 세포이다. 이식편대숙주반응이라는 것은 이식되어온 조직에 존재하는 타인의 혈구들이 숙주의 세포를 공격하는 것을 말한다. 즉 이식되어온 조직과 함께 들어온 혈구들이 이식을 받은 사람의 세포를 타인의 것으로 인지해서 공격하는 현상이다. 이것은 이식을 받은 사람의 면역상태가 정상적일 경우에는 일어나지 않는데 왜냐하면 면역상태가 정상일 경우에는 이식되어온 장기와 더불어 들어온 타인의 혈구들을 이식을 받은 사람의 혈구가 타인의 것으로 인지해서 공격을 하고 숫적으로 유리하여 모두 죽일 수가 있기 때문이다. |

| 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) |
| sensation time | The minimal time a visual image must be exposed in order to be perceived. (05 Mar 2000) |
| reaction time |
the time it takes a driver to react to the green starting light on the Christmas Tree, measured in thousandths of a second. The reaction-time counter begins when the last amber light flashes on the Tree and stops when the vehicle clears the stage beam.

| reaction time |
The time provided by a sealer for you to react to a contaminant. Example; Red wine spill on white marble floor; with some sealers you may get a reaction time of a few minutes before the wine gets through and begin to stain, with others it can be anywhere from 2 to 12 hours. With no sealer you have very little reaction time if any. top Riven Natural finish of quarried stone (esp. slate) the rippled effect that is present when slate is split along its?natural cleavage lines.

| reaction time |
It's the amount of time measured in thousandths of a second that it takes the driver to react to the light and apply the throttle. In other words, the amount of time elapsed from the moment the green light flashes and when the drag car trips the starting beam. Drag races are won or lost on the starting line, so practice on improving your reaction times with a practice tree. ...
