| 영문 | ESR(Erythrocyte Sedimentation Rate) | 한글 | 적혈구침강속도, 혈침 |
|---|---|---|---|
| 설명 | 혈액이 응고되는 것을 방지하는 항응고제를 넣은 혈액을 침강용 유리관에 넣어 가만히 세워 두었을 때 적혈구가 가라앉는 속도를 이르는 말이다. 1918년 스웨덴의 병리학자 파레우스의 창안에 의한 것이다. 측정방법으로 여러 가지가 있는데, 국제표준법으로는 1973년 웨스터그렌법의 1시간법이 선정되었으며, 1977년 그것을 개정하여 각국에서 쓰도록 권장하고 있다. 1시간 후 침강용 유리관 위쪽의 혈장기둥의 높이를 mm로 읽어, 그것을 적혈구침강의 1시간값으로 한다. 만약 혈장과 적혈구의 경계가 선명하지 못한 경우, 적혈구의 밀도가 그 이하에서는 일정하다고 여겨지는 곳의 눈금을 읽어 적혈구침강의 1시간값으로 한다. 측정 때의 실내온도는 18~25도로 한다. 일반적으로 이보다 온도가 높은 경우는 혈침반응이 촉진되며, 낮은 경우는 늦어진다. 정상 값은 2~10mm(남자), 3~15mm(여자)이며 15세 이하의 어린이, 50세 이상의 고령자에서는 약간 높다. |

| heparin, low-molecular-weight | <chemical> Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of haemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |

| infant, low birth weight | An infant having a birth weight of 2500 gm. (5.5 lb.) or less but infant, very low birth weight is available for infants having a birth weight of 1500 grams (3.3 lb.) or less. (12 Dec 1998) |
| infant, very low birth weight | An infant having a birth weight of 1500 grams (3.3 lb.) or less. (12 Dec 1998) |
| 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) |
| kininogen, low-molecular-weight | A protein, molecular weight 50 kD, located in various normal tissues. Upon cleavage by kallikrein or other kallikreins, it forms kallidin. Kallidin, in turn, is converted into bradykinin. (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) |
