| 설명 | 허파 성숙도의 미숙으로 허파꽈리를 팽창시키는 물질(표면활성제)이 부족하여 호흡곤란이 초래되는 병으로서 미숙아에 호발하는데, 출생시 임신기간보다도 허파 성숙 정도가 더 관여된다. 단일 병으로서는 사망률이 가장 높으며(약 30%), 신생아의 대표적인 병이다. 임상적으로는 미숙아, 생후 6~8시간내 호흡곤란증세 출현과 생후 24~48시간의 증상 악화, 생후 2~3일간 인공적으로 산소를 공급하지 않으면 호흡을 계속시킬 수가 없으며 점점더 산소의 공급 의존도가 높아지며, 동맥혈액속의 산소농도가 내려가고 이산화탄소의 농도가 높으며, 흉부 방사선 소견을 참작하여 진단한다. 환아는 숙련된 간호 인력과 첨단 의료 장비가 설치된 신생아 집중 치료실에서 치료하여야 한다. 예후는 증세의 경중에 따라 다르고 사망률은 30~50% 된다. 어떤 아기에 있어서는 치료 후에 눈이나 기관지허파 계통에 장애를 일으키는 산소중독증이 보고되고 있다. |

| ANESR | apparent norepinephrine secretion rate |
| biological transport | The movement of materials (including biochemical substances and drugs) across cell membranes and epithelial layers, usually by passive diffusion. (12 Dec 1998) |
|---|---|
| biological transport, active | The movement of materials across cell membranes and epithelial layers against an electrochemical gradient, requiring the expenditure of metabolic energy. (12 Dec 1998) |
| vectorial transport | <physiology> Transport of an ion or molecule across an epithelium in a certain direction (e.g. absorption of glucose by the gut). Vectorial transport implies a nonuniform distribution of transport proteins on the plasma membranes of two faces of the epithelium. (06 Mar 2000) |
| paracellular transport | Solvent movement across an epithelial cell layer through the tight junctions between cells. Compare: transcellular transport. (05 Mar 2000) |
| vesicular transport | <cell biology> Process of transport of material across an epithelium by uptake on one face into a coated vesicle, which may then be sorted through the trans Golgi network and transported to the opposite face in another set of vesicles. (17 Mar 1998) |
| passive transport | <biochemistry, physiology> The movement of a substance, usually across a plasma membrane, by a mechanism that does not require metabolic energy. See: active transport, transport protein, facilitated diffusion, ion channels. (18 Nov 1997) |
| renal tubular transport, inborn errors | Genetically determined disorders of the reabsorptive functions of the kidney with regard to specific nephron segments responsible for specific transport functions, classifiable by proximal nephron function, loop of henle function, and distal nephron function. The transport defects can be selective or nonselective. (12 Dec 1998) |
| respiratory transport | The processes of gas exchange and various metabolic functions taking place in the lung, generally at the alveolar level. (12 Dec 1998) |
| retrograde axonal transport | <cell biology> The transport of vesicles from the synaptic region of an axon towards the cell body: involves the interaction of MAP1C with microtubules. (11 Jan 1998) |
| channel transport | <radiobiology> In inertial fusion research using light ion drivers, describes the use of current-carrying plasma channels (which are magnetically confined to the channel) to transport electron or ion beams between the ion diode and the fusion target. This allows the ion source to stand back from the target. (09 Oct 1997) |
| reverse electron transport | <chemistry> The energy-dependent movement of electrons against the thermodynamic gradient to form a strong reductant from a weaker electron donor. (11 Jan 1998) |
| cotranslational transport | <cell biology> Process whereby a protein is moved across a membrane as it is being synthesised. This process occurs during the translation of the message at membrane associated ribosomes in rough endoplasmic reticulum during the synthesis of secreted proteins in eukaryotic cells. (18 Nov 1997) |
| coupled transport | The linked, simultaneous transport of two substances across a cell membrane (or another intracellular membrane). If the two substances are moving in the same direction (both into the cell or both out of the cell) it is called symport. If the two substances are moving in opposite directions (one moves into the cell while the other moves out) it is called antiport. (09 Oct 1997) |
| hydrogen transport | The transfer of hydrogen from one metabolite (hydrogen donor) to another (hydrogen acceptor) through the action of an enzyme system; the donor is thus oxidised and the acceptor reduced. (05 Mar 2000) |
| sperm transport | Passive transport or active migration of spermatozoa from the testes through the male genital system as well as within the female genital system. (12 Dec 1998) |
