| 설명 | 혈액응고란 지혈의 한 과정으로 섬유소란 물질을 만들어 내는 과정이다. 이 섬유소란 물질은 손상된 혈관의 부위에 작용하여 여러 가지 세포들을 얽어 묶는 역할을 하여 결국 손상된 혈관에서 혈액의 소실을 막는다. 혈액응고는 다음과 같은 3단계로 이루어진다. 첫번째 단계는 혈관손상에 의해서 prothrombin activator라는 것이 만들어지는 단계이다. 두번째 단계는 이 prothrombin activator라는 물질에 의해서 혈액속에 있는 프로트롬빈이라는 물질이 트롬빈이라는 물질로 바뀌는 단계이다. 세번째 단계는 트롬빈이라는 물질에 의해서 섬유소원이라는 물질이 섬유소으로 바뀌는 단계이다. 응고작용은 크게 2가지로 나뉘는데, 외인성 응고인자와 내인성 응고인자가 그것이다. 외인성 응고인자와 내인성 응고인자는 각기 별개로 작용하지만, 결국은 마지막 과정에서 하나로 만나서 섬유소원을 섬유소(응고작용의 마지막 단계에 생성되며 단단하고 풀리지 않는 매듭을 형성하여 지혈작용을 완성한다)으로 만들어 응고작용을 나타낸다. |

| 설명 | 몸에 상처가 나서 출혈이 있었을 경우에 피가 멎는데 까지 걸리는 시간을 출혈시간이라고 한다. 사람의 몸에 상처가 나서 출혈이 있을 경우에 이것을 막고 피를 더이상 나지 않게 하는 것을 지혈이라고 한다. 지혈의 과정에는 크게 두 가지 단계가 있다. 첫번째 단계는 혈소판들이 상처가 나서 손상된 혈관의 부위를 막는 것이다. 이렇게 하면 우선 혈관의 손상부위로부터 피가 나오는 것을 막을 수가 있다. 다음의 단계는 상처를 막고 있는 혈소판위에 여러 가지 물질들이 작용해서 더욱 단단하게 하여 상처가 난 혈관에서 피가 새는 것을 영구히 막는 것이다. 쉽게 말하면 혈소판은 벽돌에 해당하는 것이고 두번째 과정에 참여하는 물질들은 시멘트에 해당하는 것이다. 이 두 과정이 완전할 경우에 지혈이 순조롭게 일어난다. 출혈시간은 위에서 설명한 지혈의 두가지 과정 중에서 첫번째 과정에 의해서만 영향을 받는다. 즉 손상된 혈관을 막아주는 벽돌에 해당하는 혈소판의 기능만 정상일 경우에 출혈시간은 정상으로 나온다. 만약 혈소판의 기능에 이상이 있는 경우에는 자연히 출혈시간이 길어진다. |

| rise | 1. To move from a lower position to a higher; to ascend; to mount up. Specifically: To go upward by walking, climbing, flying, or any other voluntary motion; as, a bird rises in the air; a fish rises to the bait. To ascend or float in a fluid, as gases or vapors in air, cork in water, and the like. To move upward under the influence of a projecting force; as, a bullet rises in the air. To grow upward; to attain a certain heght; as, this elm rises to the height of seventy feet. To reach a higher level by increase of quantity or bulk; to swell; as, a river rises in its bed; the mercury rises in the thermometer. To become erect; to assume an upright position; as, to rise from a chair or from a fall. To leave one's bed; to arise; as, to rise early. "He that would thrive, must rise by five." (Old Proverb) To tower up; to be heaved up; as, the Alps rise far above the sea. To slope upward; as, a path, a line, or surface rises in this direction. "A rising ground." To retire; to give up a siege. "He, rising with small honor from Gunza, . . . Was gone." (Knolles) To swell or puff up in the process of fermentation; to become light, as dough, and the like. 2. To have the aspect or the effect of rising. Specifically: To appear above the horizont, as the sun, moon, stars, and the like. "He maketh his sun to rise on the evil and the good." To become apparent; to emerge into sight; to come forth; to appear; as, an eruption rises on the skin; the land rises to view to one sailing toward the shore. To become perceptible to other senses than sight; as, a noise rose on the air; odour rises from the flower. To have a beginning; to proceed; to originate; as, rivers rise in lakes or springs. "A scepter shall rise out of Israel." (Num. Xxiv. 17) "Honor and shame from no condition rise." (Pope) 3. To increase in size, force, or value; to proceed toward a climax. Specifically: To increase in power or fury; said of wind or a storm, and hence, of passion. "High winde . . . Began to rise, high passions anger, hate." To become of higher value; to increase in price. "Bullion is risen to six shillings . . . The ounce." (Locke) To become larger; to swell; said of a boil, tumour, and the like. To increase in intensity; said of heat. To become louder, or higher in pitch, as the voice. To increase in amount; to enlarge; as, his expenses rose beyond his expectations. 4. In various figurative senses. Specifically: To become excited, opposed, or hostile; to go to war; to take up arms; to rebel. "At our heels all hell should rise With blackest insurrection." (Milton) "No more shall nation against nation rise." (Pope) To attain to a better social position; to be promoted; to excel; to succeed. "Some rise by sin, and some by virtue fall." (Shak) To become more and more dignified or forcible; to increase in interest or power; said of style, thought, or discourse; as, to rise in force of expression; to rise in eloquence; a story rises in interest. To come to mind; to be suggested; to occur. "A thought rose in me, which often perplexes men of contemplative natures." (Spectator) To come; to offer itself. "There chanced to the prince's hand to rise An ancient book." (Spenser) 5. To ascend from the grave; to come to life. "But now is Christ risen from the dead." (1. Cor. Xv. 20) 6.

To ascend on a musical scale; to take a higher pith; as, to rise a tone or semitone. 8. To be lifted, or to admit of being lifted, from the imposing stone without dropping any of the type; said of a form. Synonym: To arise, mount, ascend, climb, scale. Rise, Appreciate. Some in America use the word appreciate for "rise in value;" as, stocks appreciate, money appreciates, etc. This use is not unknown in England, but it is less common there. It is undesirable, because rise sufficiently expresses the idea, and appreciate has its own distinctive meaning, which ought not to be confused with one so entirely different. Origin: AS. Risan; akin to OS. Risan, D. Rijzen, OHG. Risan to rise, fall, Icel. Risa, Goth. Urreisan, G. Reise journey. CF. Arise, Raise, Rear. 1. The act of rising, or the state of being risen. 2.

Elevation or ascent of the voice; upward change of key; as, a rise of a tone or semitone. 9. The spring of a fish to seize food (as a fly) near the surface of the water.

Activation may be provided by contact with the glass tube or exposure to activators (e.g., ellagic acid, particulate silicates such as diatomaceous earth or kaolin) before addition of the calcium chloride. It is used as a screening test and to monitor heparin therapy. (12 Dec 1998) |
| relaxation time | Time taken for a system to return to the resting or ground state or a new equilibrium state following perturbation. Often used in context of receptor systems that have a refractory period after responding and then relax to a competent state.

| rise time |
Usually, the time required for a pulse to increase from 10% of its final value to 90% of its final value. Rise time is less frequently measured between the 5% and 95% points or the 1% and 99% points. Rise time is used to specify the transient response of an instrument, and is similar to its time constant, relaxation time, or response time, although these latter terms use (1 - e -1 ), or about 63%, as the fractional change in state over which time is measured, beginning at an initial value. ...

| rise time |
The time taken for a signal to rise from silence to full intensity. The tones of different instruments can be distinguished by their rise time, the tones of percussive instruments like the piano rising very rapidly and others like the tuba, more slowly. In music, "rise time" is called "attack" (see amplitude envelope). [3], [4]
