|---|---|---|---|
| 설명 | 심장의 수술에 사용되는 기계로서 심장이 수술을 받고 있는 동안 기능을 하지 못하므로 이 기능을 대신 해주는 기계이다. 이것은 대정맥과 대동맥사이에 연결이 되어서 혈액을 강제로 순환시키면서 대정맥에서 온 피에 산소를 공급하여 대동맥으로 돌려 보내는 역할을 한다. 즉 심장과 폐의 역할을 동시에 하는 기계이다. |

| 영문 | congestive heart failure | 한글 | 울혈성심장기능상실 |
|---|---|---|---|
| 설명 | 심장의 원래 기능, 즉 혈액을 말초로 보내는 펌프와 같은 기능이 거의 없어진 상태를 말한다. 피를 보내는 펌프의 역할이 멈추었으므로 심장으로 들어오는 피는 심장으로 들어오지 못하고 정맥속에서 정체하게 된다. 그리하여 혈액의 대부분이 말초의 정맥에 머물게 되어 여러 가지 증상이 나타난다. 특히 허파를 돌아 좌심방으로 들어가야하는 피가 펌프 기능이 없어져서 왼심방에 많은 피가 정체하고 있어서 들어가지 못해서 허파에 고이게 된다. 그러면 허파에 산소와 이산화탄소를 교환하는 기능이 없어져서 숨을 쉬지 못하는 결과를 낸다. 즉 숨이 차고 숨쉬기 힘든 증세가 나타난다. 또 온몸을 순환한 다음에 우심방으로 들어와야하는 피도 우심방으로 들어오지 못해서 말초에 정체하므로 온몸이 붓게 된다. |

| Hyrtl's loop | A communicating loop between the right and left hypoglossal nerves, lying between the geniohyoid and genioglossus muscles or in the substance of the geniohyoid; it is found in about one in ten persons. Synonym: Hyrtl's anastomosis. (05 Mar 2000) |

| stem and loop structure | <molecular biology> The structure of tRNAs is so termed because it has four base paired stems and three loops (not base paired), one of which contains the anticodon. (18 Nov 1997) |
| nephronic loop | The U-shaped part of the nephron extending from the proximal to the distal convoluted tubules, consisting of descending and ascending limbs, located in the medulla renalis and medullary ray. Synonym: Henle's ansa, Henle's loop. (05 Mar 2000) |
| subclavian loop | A nerve cord connecting the middle cervical and stellate sympathetic ganglia, forming a loop around the subclavian artery. Synonym: subclavian loop, Vieussens' ansa, Vieussens' loop. (05 Mar 2000) |
| displacement loop | <molecular biology> A structure that can sometimes be seen on DNA which forms when a small area of the double-stranded molecule comes apart and becomes two single strands. The result is a structure shaped like the letter D. Single-stranded binding proteins are usually present to hold the strands apart for the purpose of DNA replication. (09 Oct 1997) |
| d loop | <molecular biology> A structure that can sometimes be seen on DNA which forms when a small area of the double-stranded molecule comes apart and becomes two single strands. The result is a structure shaped like the letter D. Single-stranded binding proteins are usually present to hold the strands apart for the purpose of DNA replication. (09 Oct 1997) |
| double loop hernia | The presence of two loops of intestine in a hernial sac. Synonym: double loop hernia. (05 Mar 2000) |
| Ivy loop wiring | Placement of a wire around two adjacent teeth to provide an attachment for intermaxillary elastics. (05 Mar 2000) |
| T loop of RNA | <molecular biology> The T loop of tRNA is the region of the molecule that is responsible for ribosome recognition. (16 Dec 1997) |
| Tphi CG loop | <molecular biology> The T loop of tRNA is the region of the molecule that is responsible for ribosome recognition. (16 Dec 1997) |
| lenticular loop | The pallidal efferent fibres curving around the medial border of the internal capsule. Synonym: ansa lenticularis, lenticular ansa. (05 Mar 2000) |
| loop | 1. A fold or doubling of a thread, cord, rope, etc, through which another thread, cord, etc, can be passed, or which a hook can be hooked into; an eye, as of metal; a staple; a noose; a bight. "That the probation bear no hinge, nor loop To hang a doubt on." (Shak) 2. A small, narrow opening; a loophole. "And stop all sight-holes, every loop from whence The eye of Reason may pry in upon us." (Shak) 3. A curve of any kind in the form of a loop. 4. A wire forming part of a main circuit and returning to the point from which it starts. 5. <physics> The portion of a vibrating string, air column, etc, between two nodes; called also ventral segment. Loop knot, a single knot tied in a doubled cord, etc. So as to leave a loop beyond the knot. Origin: Cf. Ir. & Gael. Lub loop, noose, fold, thong, bend, lub to bend, incline.

| loop bioreactors | Bioreactors in which the fermenting material is cycled between a bulk tank and a smaller tank or loop of pipes. The circulation helps mix the materials and ensures that gas injected into the fermenter is well distributed. (14 Nov 1997) |
| loop diuretic | A class of diuretic agents (e.g., furosemide, ethacrynic acid) that act by inhibiting reabsorption of sodium and chloride, not only in the proximal and distal tubules but also in Henle's loop. (05 Mar 2000) |
| loop electrocautery excision procedure | Electrocautery excisional biopsy of abnormal cervical tissue. (05 Mar 2000) |
