| 설명 | 사람의 적혈구 표면에는 여러 가지 항원성을 가진 물질이 존재한다. 즉 면역학적 반응을 일으킬 수 있는 물질을 표면에 가지고 있다. 그리고 사람의 피속에는 이것과 반응할 수가 있는 항체도 존재한다. 사람의 혈액은 이것에 따라 몇가지 형으로 분류할 수가 있고, 이것을 혈액형이라고 한다. 혈액형은 적혈구 표면에 있는 어떤 물질을 기준으로 하느냐에 따라서 여러 가지로 분류될 수 있다. 대표적인 혈액형의 구분 방법에는 ABO혈액형과 Rh혈액형이 있다. 1. ABO 혈액형 가장 많이 사용되고 있는 혈액형 구분법. 적혈구 표면에는 A, B형의 두 가지 물질을 하나, 혹은 둘, 또는 하나도 가지지 않을 수가 있다. 그리고 피속에는 이것과 반응해서 적혈구를 파괴하거나 응집시킬 수 있는 물질(항체)이 존재한다. 물론 자신의 적혈구가 가지고 있는 물질에 대한 항체는 존재하지 않는다. -A형 혈액형－적혈구 표면에 A항원, 혈액속에 B에 대한 항체 -B형 혈액형－적혈구 표면에 B항원, 혈액속에 A에 대한 항체 -AB형 혈액형－적혈구 표면에 A, B항원, 혈액속에 A,B에 대한 항체를 가지지 않는다. -O형 혈액형－적혈구 표면에 A, B항원 모두를 가지지 않고, 혈액속에 A, B에 대한 항원을 모두 가진다. 대개 이것을 이용하여 수혈의 타당성 여부를 조사한다. 만약 A형 혈액형을 가진 사람의 피를 B형 혈액형의 사람에게 수혈하면 B형 혈액형을 가진 자의 피속에 있는 A에 대한 항체때문에 들어온 A형의 적혈구는 파괴되거나, 응집이 된다. O형의 혈액형을 가진 사람의 혈액의 적혈구는 표면에 A, B의 어떠한 물질도 가지고 있지 않아서 어떠한 혈액형을 가진 사람에게 수혈해도 반응을 일으키지 않는다. 이와 같은 원리로 AB형의 혈액형을 가진 사람은 혈액속에 A, B에 대한 항체를 모두 가지고 있지 않으므로 어떠한 혈액형이라도 받을 수가 있다. 2. Rh혈액형 적혈구표면에 있는 D라는 물질을 기준으로 하여 혈액형을 나누는 방법. 만약 D라는 물질이 적혈구의 표면에 존재하면 Rh(+), 존재하지 않으면 Rh(－)라고 한다. ABO혈액형에서와 같이 Rh(+)혈액형을 가지는 사람의 피속에는 D라는 물질에 대한 항체가 존재하지 않지만 Rh(－)혈액형을 가진 사람의 피속에는 D에 대한 항체가 존재한다. ABO혈액형과 마찬가지로 수혈의 타당성을 결정하는데 중요한 역할을 한다. |

|---|---|---|---|
| 설명 | 혈액속의 요소를 말한다. 요소란 단백질이나 아미노산의 최종산물로써 간에서 생산되어 콩팥으로 배출되는 물질이다. 이것은 인간에게 없어서는 안될 단백질과 아미노산의 산물이므로 사람에겐 언제나 일정량이 생산된다. 콩팥의 기능이 나쁠 경우에는 이것이 콩팥으로 배설되지 못하고 몸속에 축적된다. 그러므로 콩팥의 기능측정에 이것이 이용 된다. |

| 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) |
