| 영문 | lung cancer | 한글 | 폐암 |
|---|---|---|---|
| 설명 | 허파에 생기는 악성종양이다. 가장 예후가 나쁜 종양중의 하나로써 조기발견이 어렵고 증세 또한 늦게 나타나서, 그 종양의 종류에 따라 다르나 치료후에도 대개 8%만이 5년 생존이 가능한 악성종양이다. 유발인자로는 대표적으로 담배가 알려져 있으며, 유전적인 요소도 어느 정도 기여하는 것으로 알려져 있다. |

| 영문 | cancer chemotherapy | 한글 | 항암화학요법 |
|---|---|---|---|
| 설명 | 화학적 물질을 이용하여 암을 치료하는 것을 말한다. 이때 사용되는 물질을 항암제라고 한다. 이상적인 항암제는 정상적인 세포에는 이상이 없고 단지 암세포에만 치명적인 효과를 나타내어야 한다. 이렇게 하려면 암세포만의 특이한 특성을 이해하고 그곳에만 작용하는 약물을 개발하여야 한다. 최근 대부분의 항암제는 암세포가 정상 세포에 비하여 월등히 증식을 빨리한다는 특성을 이용하고 있다. 증식이 빠르다는 것은 유전정보를 가지고 있는 DNA의 복제가 빠르다는 것을 의미한다. 만약 DNA의 복제를 방해한다면 증식이 아주 빠른 암세포에게는 치명적이지만 영원히 증식을 하지 않는(DNA의 복제가 거의 필요없는)신경세포나 증식이 암세포에 비해서 아주 느린 정상세포에서는 거의 영향을 주지 못한다. 하지만 신체에서도 정상적으로 증식이 암세포와 비슷한 수준으로 일어나는 세포가 있는데 그것은 머리카락을 만드는 모낭세포와 소화관의 점막을 이루는 세포와 혈액의 세포를 만드는 골수 세포이다. 그러므로 항암제를 사용할 경우 이런 세포가 암세포와 마찬가지로 치명적인 영향을 입을 것은 당연하다(그래서 항암제 치료시엔 머리가 빠지고 소화불량이 잘온다). |

| chloride current | Flow of chloride ions through chloride selective ion channels. (18 Nov 1997) |
|---|---|
| current | <chemistry> The amount of charge carried per unit time. (09 Jan 1998) |
| current density | <radiobiology> Amount of current flowing through a substance, per unit area perpendicular to the direction of current flow. (See also density) (09 Oct 1997) |
| current drive | <radiobiology> Any of a variety of techniques used to cause current flow in a plasma. See inductive current drive, RF current drive, non-inductive current drive. Usually applied to schemes used to generate current in tokamaks and other toroidal devices which require internal plasma currents. See: bootstrap current. (09 Oct 1997) |
| current of injury | The current set up when an injured part of a nerve, muscle, or other excitable tissue is connected through a conductor with the uninjured region; the injured tissue is negative to the uninjured. Synonym: demarcation current. (05 Mar 2000) |
| halo current | <radiobiology> Currents in the halo region of a plasma discharge. See: halo. (09 Oct 1997) |
| high frequency current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
| dark current | <physiology> Current caused by constant influx of sodium ions into the rod outer segment of retinal photoreceptors and that is blocked by light (leading to hyperpolarization). The plasma membrane sodium channel is controlled through a cascade of amplification reactions initiated by photon capture by rhodopsin in the disc membrane. (18 Nov 1997) |
| d'Arsonval current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
| demarcation current | The current set up when an injured part of a nerve, muscle, or other excitable tissue is connected through a conductor with the uninjured region; the injured tissue is negative to the uninjured. Synonym: demarcation current. (05 Mar 2000) |
| descending current | The direction of current flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending current. Synonym: centrifugal current. (05 Mar 2000) |
| direct current | (DC) Electric current which travels continuously in the same direction over a sustained period of time, contrast with AC (Alternating Current) which oscillates as a function of time. (09 Oct 1997) |
| inductive current drive | <physics> Method to drive current in a toroidal plasma by using the torus of conducting plasma as the second coil in a transformer. The primary coil usually runs down the centre of the torus, changes in the current driven through the primary coil create changing magnetic fields which drive current in the plasma. The current thus driven can be used to heat the plasma as well (see also ohmic heating, induction). (09 Oct 1997) |
| Tesla current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
| eddy current | <radiobiology> Electric current induced inside a conductor when the conductor (a) moves through a nonuniform magnetic field, or (b) experiences a change in the magnetic flux through its surface. (09 Oct 1997) |
