| 영문 | dumping syndrome | 한글 | 덤핑증후군 |
|---|---|---|---|
| 설명 | 부분적 위절제술 또는 위빈창자연결술을 받은 환자에게서 음식을 먹은 후에 일어나는 증후군이다. 명치 부분의 팽만감과 압박감-구역-구토 등의 복부증상 외에 탈력감-현기증-발한-가슴띔 등 순환장애 증상이 따른다. 그런 증상은 섭취한 음식물이 위에서 작은창자로 추락하듯 배출됨으로써 음식물의 무게로 인해 소화관이 아래쪽으로 쳐져든다. 작은창자벽이 급격하게 늘어나든가, 화학적 자극으로 인한 작은창자벽의 자율신경반사, 작은창자벽의 삼투압에 의해 소화관으로 수분이 급속히 대량 이동하여 순환되는 혈액의 양이 감소하여 일어난다. 주로 식사요법으로 치료하여, 약물요법으로는 아트로핀-헥사메토늄-페노바르비탈-탄산수소나트륨의 사용 및 포도당주사도 효과가 있다. 수술요법은 빌로스(Billroth) 제1법으로의 변환, 대용위의 제작 등이 있으나 확실한 것은 아니다. |

| 설명 | 영유아나 소아가 부모 등의 보육자나 형제자매로부터 반복해서 신체적인 학대를 받아 발생하는 각종 증사의 총칭이다. 1962년 켐프(Kempe)에 의해 명명되었다. 상처를 받은 시기가 서로 차이가 있는 외상이 몸 전체 여러 곳에서 관찰되는 것이 특징이다. 피부의 손상과 얼룩출혈, 경질막하 혈종, 골절 등이 많고 극단적인 경우는 영구적 뇌손상과 죽음에 이르는 경우도 있다. 학대동기는 피해자 입장에서는 육체적-정신적 발육부전, 쌍둥이, 기형, 밤중에 우는 것, 야뇨증, 장난, 반항적 태도 등이 있으며 가해자 입장에서는 보육자의 아이에 대한 애정결핍과 과잉 기대, 육아에 대한 무지, 형제자매에 대한 시샘, 정신병, 신경증, 지능저하, 알코올 중독 등이 있고, 또 생활환경의 입장에서는 빈곤, 부부 불화, 핵가족이면서 사회적으로 고립된 가정 등을 들 수 있다. |

| 영문 | severe acute respiratory syndrome(SARS) | 한글 | 사스 |
|---|---|---|---|
| 설명 | 중국 광동 지역에서 가장 먼저 발생한 전염성 호흡기 질환으로 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. |

|---|---|---|---|
| 설명 | 임신기간 중에 산모가 풍진에 걸리면 이 풍진 바이러스는 태반을 통해서 태아에게 전달되어서 태아의 풍진감염을 일으킨다. 임신 첫 3개월 동안, 특히 임신 첫달에 태아가 풍진의 감염을 받으면, 신생아에서 선천기형, 즉 눈에서 촛점을 정확히 맞추어주는 렌즈의 역할을 하는 수정체의 혼탁(백내장), 심장기형, 귀머거리 및 심한 지능박약을 동반하는 소두증 등이 발생하는 수가 많다. |

| ear, low-set | A minor anomaly involving an ear situated down below its normal location. Technically, the ear is low-set when the helix (of the ear) meets the cranium at a level below that of a horizontal plane through both inner canthi (the inside corners of the eyes). The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |

| low-activation materials | <radiobiology> In fission reactors, one is forced to deal with the radioactive byproducts of the fission process, but in fusion reactors one generally has a choice of what materials to expose to neutrons produced by the fusion process. A major problem for fusion reactors is developing materials (such as for the reactor vacuum vessel structure) which can be exposed to high levels of neutron bombardment without becoming permanently radioactive. Candidate structural materials which have relatively low induced radiactivation (generally relative to stainless steel) are known as low-activation materials, these include titanium, vanadium, and silicon-carbide.

| low affinity platelet factor IV | Cytokine, produced from platelet basic protein, that acts as a growth factor. (18 Nov 1997) |
| low aspect ratio | <physics> An aspect ratio for a torus that is small (minor radius is almost as big as major radius). There are many fusion devices which are designed to have a low aspect ratio. Such devices look more like tractor tires than bicycle tires, as toruses go. There are reasons to believe that low aspect ratio devices will offer some advantages for a fusion reactor. Usually, ease of theoretical and/or numerical analysis is not one of these advantages. (16 Mar 1998) |

| low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats in the bloodstream. High levels of low density lipoprotein are considered a positive risk factor for the development of coronary artery disease. Less than 130 mg/dl is desirable, 130 to 159 mg/dl is borderline high, over 160 is considered high. Acronym: LDL (10 Jan 1998) |
| low density lipoprotein receptor | <biochemistry> A cell surface protein that mediates the endocytosis of low density lipoprotein by cells. Genetic defects in low density lipoprotein receptors lead to abnormal serum levels of low density lipoprotein and hypercholesterolaemia. (16 Mar 1998) |
| low-density lipoprotein receptors | Receptors on the surface of cells, especially liver cells, which bind to low density lipoprotein and promote clearance of LDL from the plasma. (05 Mar 2000) |

| low-fat diet | A diet containing minimal amounts of fat.Diets containing low amounts of fat and cholesterol are designed to reduce the risk of heart disease and, in some cases, cancer. Dozens of such diets have been promulgated, both by medical and lay advisors. Their popularity can be attributed in part to clinical studies that have, since the 1980s, revealed, on the one hand, the hazards of eating high-fat, high-cholesterol foods and, on the other, the benefits of ingesting less saturated fat and LDL (low density lipoprotein) cholesterol. Although coronary deaths have been reduced by roughly 30% since 1970, the aim of health officials is to further reduce heart attack rates. The average cholesterol level among adult Americans has fallen from 213 to 205 mg/dl since 1978. However, the National Cholesterol Education Program recommends that individuals maintain a total cholesterol level of no more than 200 mg/dl, with LDL at less than 130 mg/dl and HDL (high density lipoprotein) around 60 mg/dl. About one-half of American adults exceed those recommendations. Low-fat, low-cholesterol diets are rich in whole grains, fresh fruits and vegetables, and legumes, and limit or exclude consumption of processed oils, dairy products, nuts and seeds, and meats. See atherosclerosis, free radicals. (05 Mar 2000) |
