| 영문 | sudden infant death syndrome | 한글 | 영아급사증후군 |
|---|---|---|---|
| 설명 | 한 살 이하의 건강한 아기가 아무런 조짐이나 원인 없이 갑자기 사망했을 경우에 내리는 진단이다. 이 증후군은 생후 1~4개월 사이에 가장 많이 발생하며, 대부분 밤 10시에서 오전 10시 사이에 발생한다. 조산하거나 부모가 흡연자일 경우, 20세 이하 산모의 초산, 임신전 건강관리에 소홀한 산모에게서 태어난 영아에게서 많이 발생한다. 이 증후군으로 사망한 영아의 형제일 경우 일반적인 영아보다 걸릴 확률이 높은 것으로 알려져 있다. |

| 영문 | severe acute respiratory syndrome(SARS) | 한글 | 중증급성호흡증후군 |
|---|---|---|---|
| 설명 | 중국 광동 지역에서 가장 먼저 발생한 전염성호흡기병으로 세계보건기구(WHO)에서 ‘중증급성호흡증후군(SARS)'으로 명명했다. 섭씨 38도 이상의 고열과 기침, 호흡곤란, 저산소증, X선상의 폐렴증상 중 하나 이상의 증상이 나타나며, 두통, 근육통, 식욕부진, 피로감, 발진, 설사를 동반할 수 있다. 초기 증상은 감기와 비슷하지만 폐렴으로 발전하면 치명적일 수 있다. 현재 밝혀진 감염경로는 환자가 재채기나 기침할 때 내뿜는 침방울이고, 이것이 다른 사람의 호흡기로 들어갈 때 전염된다. 침방울이 전달되는 거리는 보통 1m로 보고 있다. 공기를 통해 전염이 가능하다는 주장이 제기됐지만 아직 확인되지 않았다. 원인균은 변종 코로나바이러스로 밝혀졌다. |

| 영문 | syndrome | 한글 | 증후군 |
|---|---|---|---|
| 설명 | 증상의 집합. 어떤 질병의 징후의 총합을 말한다. 대개 그 원인은 알 수 없으나, 증상이 복합적으로 나타나고 이에 대한 치료가 일정한 경우 하나의 증후군으로 취급한다. |

| 영문 | asphycitic syndrome | 한글 | 질식증후군 |
|---|---|---|---|
| 설명 | 호흡기중의 산소결핍에 의한 생명정지의 절박한 상태, 또는 실제로 정지가 일어난 상태, 고이산화탄소증과 저산소증 혹은 무산소증 등이 동반된다. 외계 폐의 고통이 두절되어 폐의 호흡작용이 장애되는 것(외질식)과 가스나 약제에 의해 생체내 조직의 가스교환이 방해를 받는 것(내질식)이 있다. 일반적으로 외질식을 가리키는 경우가 많다. 원인으로서는 코나 입 등 호흡입구의 폐색, 음식물이나 이물에 의한 기도폐색, 목조임, 물 또는 분비물 등이 기도로 들어가는 것, 약물 또는 파상풍에 의한 호흡근마비, 매몰 등 외력에 의한 호흡운동의 저지, 공기 중의 산소부족 및 유독가스의 흡입 등을 들 수 있다. |

| 영문 | nephrotic syndrome | 한글 | 콩팥증후군 |
|---|---|---|---|
| 설명 | 콩팥의 토리이상에 의한 단백질손실이 주원인인 병이다. 그 정의는 성인의 요단백량(소변에 섞여 나오는 단백질의 양. 대개 정상인에서는 나오지 않거나, 혹은 아주 소량이 나올 뿐임)이 하루 3.5mg이상, 또한 소아에서는 혈중 알부민농도가 2.5mg이하, 하룻동안 소변으로 나오는 요단백량을 시간당 계산했을 때 시간당 40mg이상인 경우이다. 따라서 콩팥증후군이란 위의 정의에 합당하기만 하면 모두 해당되므로, 여러 가지 원인에 의한 콩팥이상으로서 단백질의 지나친 배출을 나타내는 질병의 집합체를 뜻한다. 대개 증상은 지나친 혈중단백질의 감소로 인한 부종, 그리고 이차적인 증상으로 발생한 고지질혈증, 감염감수성의 증가, 고혈압 등이다. 치료와 예후는 콩팥증후군을 나타내는 각 원인에 따라 다르나, 대개 소아에 발생한 경우 스테로이드제재에 의한 치료효과가 높다. |

| medullary membrane | <anatomy> The layer of vascular connective tissue lining the medullary cavities of bone. Origin: NL, fr. Gr. + a bone. Source: Websters Dictionary (01 Mar 1998) |

| pemphigoid, benign mucous membrane | A chronic blistering disease with predilection for mucous membranes and less frequently the skin, and with a tendency to scarring. It is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement. (12 Dec 1998) |
| reticular membrane | The membrane formed by cuticular plates of the cells of the spiral organ of Corti; it appears netlike when viewed from above. Synonym: membrana reticularis. (05 Mar 2000) |
| membrane | A thin layer of tissue which covers a surface, lines a cavity or divides a space or organ. (18 Nov 1997) |
| membrane attack complex | <immunology> A term originally used to refer to the heat labile factor in serum that causes immune cytolysis, the lysis of antibody coated cells and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed components of complement and are designated by the symbols C1 through C9. C1 is a calcium dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower case letter suffixes, for example, C3a. Inactivated fragments may be designated with the suffix i, for example C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol for example C1 or C4b, 2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3, C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3, activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins or chemotactic factors. (05 Jan 1998) |
| membrane bone | A bone that develops embryologically within a membrane of vascularised primitive mesenchymal tissue without prior formation of cartilage. (05 Mar 2000) |
| membrane-bound proton-translocating PPi synthase | <enzyme> From rhodospirillum rubrum; functions as an alternative coupling factor; n,n'-dicyclohexylcarbodiimide-sensitive; catalyses the phosphorylation of pi to ppi, the hydrolysis of ppi and the concomitant translocation of proton across the plasma membrane Registry number: EC 3.6.1.- Synonym: h(+)-ppi synthase (26 Jun 1999) |
| membrane capacitance | The electrical capacitance of a membrane. Plasma membranes are excellent insulators and dielectrics: capacitance is the measure of the quantity of charge that must be moved across unit area of the membrane to produce unit change in membrane potential and is measured in Farads. most plasma membranes have a capacitance around 1 microfarad cmexp 2. (18 Nov 1997) |
| membrane-coating granule | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| membrane depolarisation | The process or act of neutralising polarity, depriving of polarity, or the result of such action; reduction to an unpolarised condition. <physiology> The reversal of the resting potential in excitable cell membranes when stimulated i.e., the tendency of the cell membrane potential to become positive with respect to the potential outside the cell. A positive shift in a cells resting potential (that is normally negative), thus making it numerically smaller and less polarized, for example 90mV to 50mV. <optics> Depolarisation of light, a change in the plane of polarization of rays, especially by a crystalline medium, such that the light which had been extinguished by the analyser reappears as if the polarization had been anulled. The word is inappropriate, as the ray does not return to the unpolarised condition. Origin: Cf. F. Depolarisation. (27 Oct 1998) |
| membrane dipeptidase | <enzyme> Renal dipeptidase which metabolises thienamycin and related carbapenem antibiotic Registry number: EC 3.4.13.19 Synonym: dehydropeptidase-i, dehydropeptidase I, microsomal dipeptidase (26 Jun 1999) |
| membrane enzyme | <enzyme> An enzyme present or embedded in a biomembrane. (05 Mar 2000) |
| membrane expansion theory | That adsorption of anaesthetics into membranes so alters membrane volume and/or configuration that membrane function is affected in such a way as to produce anaesthesia. (05 Mar 2000) |
| membrane fluidity | Biological membranes are viscous 2 dimensional fluids within their physiological temperature range. (18 Nov 1997) |
| membrane fracture | Method of specimen preparation for the electron microscope in which rapidly frozen tissue is cracked so as to produce a fracture plane through the specimen. The surface of the fracture plane is then shadowed by heavy metal vapour, strengthened by a carbon film and the underlying specimen is digested away, leaving a replica that can be picked up on a grid and examined in the transmission electron microscope. The great advantage of the method is that the fracture plane tends to pass along the centre of lipid bilayers and it is therefore possible to get en face views of membranes that reveal the pattern of Integral membrane proteins. The E face is the outer lamella of the plasma membrane viewed as if from within the cell, the P face the inner lamella viewed from outside the cell. Fracture planes also often pass along lines of weakness such as the interface between cytoplasm and membrane, so that outer and inner membrane surfaces can be viewed. Further information about the structure can be revealed by freeze etching. Extremely rapid freezing followed by deep etching has allowed the structure of the cytoplasm to be studied without the artefacts that might be introduced by fixation. (18 Nov 1997) |
