| 영문 | autonomic nervous system | 한글 | 자율신경계 |
|---|---|---|---|
| 설명 | 사람의 의지와 관계없이, 침을 흘리거나 소화운동 등과 같은 스스로 조정이 되어 움직이는 신경계이며 여기에는 다음과 같은 두 가지가 있다. 1.교감신경계(sympathetic nervous system)-사람이 위험상태에 이르렀을 경우에 흥분이 되는 자율신경계. 즉 심박수의 증가, 소화기 운동의 감소 등의 일이 이곳을 통해서 일어난다. 교감신경이 흥분되면 교감신경의 말단에서 epinephrine, norepinephrine 등의 물질이 분비되고 이것들에 의해서 말초장기가 변화를 일으킨다. 하지만 장기에 따라서 epinephrine이나 norepinephrine의 수용체를 가지고 있어서 여러 가지 다른 장기의 반응을 볼 수가 있다. 수용체는 다음과 같다. -알파수용체(alpha-receptor): 말초혈관의 수축, 기관지의 수축, 동공의 근육의 수축 -베타1수용체(beta 1-receptor): 심장에 존재하는 수용체, 심장을 빨리 뛰게하는 역할을 한다. -베타2수용체(beta 2-receptor): 혈관의 이완, 기관지의 이완, 즉 각 장기들은 그 장기가 가지고 있는 교감신경의 수용체에 따라 교감신경의 흥분(교감신경 말단에서의 epinephrine의 분비)에 대한 반응이 달라진다(예-교감신경이 흥분시에 beta 1-수용체를 가지고 있는 심장은 빨리 뛰게 된다. 교감신경 흥분시에 동공의 근육이 수축해서 동공의 크기가 커진다) 2.부교감신경계(parasympathetic nervous system)-교감신경과 반대로 작용한다. 즉 사람이 졸리거나 쉴 경우에 흥분한다. 부교감신경이 흥분할 때에는 신경의 말단에서 아세칠콜린의 분비가 일어나고 이것으로 인해서 각 장기의 변화가 일어난다. |

| 영문 | TNM staging system | 한글 | 종양병기분류계통 |
|---|---|---|---|
| 설명 | 종양의 병기(stage)를 결정하는 한 방법. T는 Tumor(종양)를 뜻하며 원발병터의 크기, 주위조직으로의 침윤정도 등에 따라 T1, T2, T3, T4(숫자가 높을 수록 주위로 침윤이 많다) 등으로 나눈다. N은 Node(림프절)를 뜻하며 침범된 림프절의 갯수, 크기, 위치 등에 따라 N1, N2, N3 등으로 나눈다. M은 Metastasis(전이)를 뜻하며 원격전이의 유무에 따라 M0, M1 등으로 나눈다. 이상의 방법으로 T, N, M이 결정되면 이들을 조합하여 최종적인 병기를 결정한다. 이렇게 결정된 병기는 치료 방침 결정과 예후 판단에 매우 중요하다. |

| 영문 | central nervous system(CNS) | 한글 | 중추신경계 |
|---|---|---|---|
| 설명 | 신경계는 중추신경계와 말초신경계로 분류할 수가 있다. 중추신경계란 뇌와 척수로 구성되어 있는 신경계를 이르는 말이다. 말초신경계란 이 이외의 모든 신경계를 이르는 말이다. |

| Ivy bleeding time test | A bleeding time test in which a sphygmomanometer is inflated to 40 mm Hg around the upper arm, a 5-mm deep incision is made on the flexor surface of the forearm, and the time is measured to cessation of bleeding. (05 Mar 2000) |
| thrombin time | Test of the conversion of fibrinogen to fibrin by thrombin in which clotting time of plasma mixed with a thrombin solution is measured. Time is prolonged by afibrinogenaemia, abnormal fibrinogen, or the presence of inhibitory substances, e.g., fibrin-fibrinogen degradation products, heparin. Reptilase, a thrombin-like enzyme unaffected by the presence of heparin, may be used in place of thrombin. (12 Dec 1998) |
| time | 1. Duration, considered independently of any system of measurement or any employment of terms which designate limited portions thereof. "The time wasteth [i. E. Passes away] night and day." (Chaucer) "I know of no ideas . . . That have a better claim to be accounted simple and original than those of space and time." (Reid) 2. A particular period or part of duration, whether past, present, or future; a point or portion of duration; as, the time was, or has been; the time is, or will be. "God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets." (Heb. I. 1) 3. The period at which any definite event occurred, or person lived; age; period; era; as, the Spanish Armada was destroyed in the time of Queen Elizabeth; often in the plural; as, ancient times; modern times. 4. The duration of one's life; the hours and days which a person has at his disposal. "Believe me, your time is not your own; it belongs to God, to religion, to mankind." (Buckminster) 5. A proper time; a season; an opportunity. "There is . . . A time to every purpose." (Eccl. Iii. 1) "The time of figs was not yet." (Mark xi. 13) 6. Hour of travail, delivery, or parturition. "She was within one month of her time." (Clarendon) 7. Performance or occurrence of an action or event, considered with reference to repetition; addition of a number to itself; repetition; as, to double cloth four times; four times four, or sixteen. "Summers three times eight save one." (Milton) 8. The present life; existence in this world as contrasted with immortal life; definite, as contrasted with infinite, duration. "Till time and sin together cease." (Keble) 9. Tense. 10. The measured duration of sounds; measure; tempo; rate of movement; rhythmical division; as, common or triple time; the musician keeps good time. "Some few lines set unto a solemn time." (Beau. & Fl) Time is often used in the formation of compounds, mostly self-explaining; as, time-battered, time-beguiling, time-consecrated, time-consuming, time-enduring, time-killing, time-sanctioned, time-scorner, time-wasting, time-worn, etc. Absolute time, time irrespective of local standards or epochs; as, all spectators see a lunar eclipse at the same instant of absolute time. Apparent time, the time of day reckoned by the sun, or so that 12 o'clock at the place is the instant of the transit of the sun's center over the meridian. Astronomical time, mean solar time reckoned by counting the hours continuously up to twenty-four from one noon to the next. At times, at distinct intervals of duration; now and then; as, at times he reads, at other times he rides. Civil time, time as reckoned for the purposes of common life in distinct periods, as years, months, days, hours, etc, the latter, among most modern nations, being divided into two series of twelve each, and reckoned, the first series from midnight to noon, the second, from noon to midnight. Common time Apparent time as reckoned from the transit of the sun's center over the meridian. 1. To appoint the time for; to bring, begin, or perform at the proper season or time; as, he timed his appearance rightly. "There is no greater wisdom than well to time the beginnings and onsets of things." (Bacon) 2. To regulate as to time; to accompany, or agree with, in time of movement. "Who overlooked the oars, and timed the stroke." (Addison) "He was a thing of blood, whose every motion Was timed with dying cries." (Shak) 3. To ascertain or record the time, duration, or rate of; as, to time the speed of horses, or hours for workmen. 4. To measure, as in music or harmony. Origin: OE. Time, AS. Tima, akin to tid time, and to Icel. Timi, Dan. Time an hour, Sw. Timme. 58. See Tide. (01 May 1998) |

| time lapse | <technique> Technique applied to speed up the action in a film or videotape sequence. In filming by taking a frame every few seconds and projecting at conventional speed (16 or 24 frames per second), the movements of cells can be greatly speeded up and then become conspicuous. With videotape, the recording is made at slow tape speed and replayed at full speed. The opposite of slow motion. (28 May 1998) |
