| 설명 | 적혈구의 기능은 산소를 운반하는데 있다. 적혈구 속에 산소와 결합을 하여 산소를 운반하는 혈색소라는 물질이 있다. 철은 이 혈색소의 중요한 부분을 이루는 것으로 철이 없으면 혈색소가 만들어질 수가 없다. 혈색소가 없으면 역시 적혈구도 만들어지지 않으므로 체내에 철이 부족하면 빈혈이 생긴다. 이 철결핍성 빈혈은 빈혈의 원인 중에서 가장 흔한 것이다(약 25%를 차지한다). 철저장량의 저하-결핍, 혈청철농도의 저하, 트란스페린량 상승, 트란스페린포화도의 저하, 혈색소농도 또는 헤마토크리트의 저하, 저색소성대적혈구를 특징으로 하는 빈혈로서, 생체 내에서 철이 장기에 걸쳐 결핍되며 그 때문에 혈색소 생산 감소에 의해 일어난다. 창자에서의 철흡수량 부족, 철의 수요 증대(유아기, 사춘기, 임신), 철소실과잉(출혈)에 의해 일어나며, 특히 사춘기에서 폐경기까지의 여성에게 많다. 증상으로서는 얼굴창백, 피로감, 피부창백, 손톱 변화(스푼 모양) 등을 나타낸다. 구강 영역에서는 혀의 접촉통, 발적, 건조감, 삼킴곤란을 수반하면 플러머-빈슨(Plummer-Vinson)증후군이라고 한다. 혈액 소견은 혈청철은 저하하며, 철결합능력의 상승, 저색소성 작은적혈구성을 나타낸다. |

| convergence excess | That condition in which an oesophoria or esotropia is greater for near vision than for far vision. (05 Mar 2000) |

| selenium excess | Too much of the mineral selenium may cause reversible changes in the hair (balding) and nails, garlic odour to the breath, intestinal distress, weakness and slower mentation (slowed mental functionning). According to the national academy of sciences, the recommended dietary allowances of selenium are 70 milligrams per day for men and 55 milligrams per day for women. (12 Dec 1998) |
| negative base excess | A measure of metabolic acidosis, usually predicted from the Siggaard-Andersen nomogram; the amount of strong alkali that would have to be added per unit volume of whole blood to titrate it to pH 7.4 while at 37캜 and at a carbon dioxide pressure of 40 mm Hg. (05 Mar 2000) |
| divergence excess exotropia | Exotropia in which the strabismus is notably greater for far vision than for near vision. (05 Mar 2000) |
| iodine excess | Just as too little iodine can cause thyroid disease, so may prolonged intake of too much iodine also lead to the development of goiter (swelling of the thyroid gland) and hypothyroidism (abnormally low thyroid activity). Certain foods and medications contain large amounts of iodine. Examples include seaweed; iodine-rich expectorants (such as sski and lugol's solution) used in the treatment of cough, asthma, chronic pulmonary disease; and amiodarone (cardorone), an iodine-rich medication used in the control of abnormal heart rhythms (cardiac arrhythmias). (12 Dec 1998) |
| iron excess | Iron overload can damage the heart, liver, gonads and other organs. Iron overload is a particular risk in people who may have certain genetic conditions (haemochromatosis) sometimes without knowing it and also in people receiving recurrent blood transfusions. According to the national academy of sciences, the recommended dietary allowances of iron are 15 milligrams per day for women and 10 milligrams per day for men. (12 Dec 1998) |
| excess | 1. The state of surpassing or going beyond limits; the being of a measure beyond sufficiency, necessity, or duty; that which exceeds what is usual or prover; immoderateness; superfluity; superabundance; extravagance; as, an excess of provisions or of light. "To gild refined gold, to paint the lily, To throw a perfume on the violet, . . . Is wasteful and ridiculous excess." (Shak) "That kills me with excess of grief, this with excess of joy." (Walsh) 2. An undue indulgence of the appetite; transgression of proper moderation in natural gratifications; intemperance; dissipation. "Be not drunk with wine, wherein is excess." (Eph. V. 18) "Thy desire . . . Leads to no excess That reaches blame." (Milton) 3. The degree or amount by which one thing or number exceeds another; remainder; as, the difference between two numbers is the excess of one over the other. <geometry> Spherical excess, the amount by which the sum of the three angles of a spherical triangle exceeds two right angles. The spherical excess is proportional to the area of the triangle. Origin: OE. Exces, excess, ecstasy, L. Excessus a going out, loss of self-possession, fr. Excedere, excessum, to go out, go beyond: cf. F. Exces. See Exceed. Source: Websters Dictionary (01 Mar 1998) |
| excess annual growth | The amount by which new forest growth exceeds removal in a year. The annual quantity of wood produced in a forest in excess of market demand. (05 Dec 1998) |
| excess lactate | The increase in lactate concentration beyond what would be expected from the increase in pyruvate concentration resulting from a change in redox potential; used as an index of anaerobic carbohydrate metabolism. (05 Mar 2000) |
| zinc excess | Too much zinc can cause gastrointestinal irritation (upset stomach), interfere with copper absorption and cause copper deficiency, and (like too little zinc) cause immune deficiency. According to the national academy of sciences, the recommended dietary allowances of zinc are 12 milligrams per day for women and 10 milligrams per day for men. (12 Dec 1998) |
| absolute refractory period | The period following excitation when no response is possible regardless of the intensity of the stimulus. (05 Mar 2000) |
| anaemia, refractory | Anaemia (a shortage of red blood cells) unresponsive to treatment. (12 Dec 1998) |
| refractory | Not readily yielding to treatment. Origin: L. Refractorius (18 Nov 1997) |
| refractory anaemia | <haematology> A form of myelodysplasia which primarily affects the red cell production by the bone marrow. In some cases the developing red cells show an internal ring of iron granules. These cells are called sideroblasts. Refractory anaemia and refractory anaemia with sideroblasts are the most common forms of myelodysplasia. Origin: Gr. Haima = blood (13 Nov 1997) |
| refractory cast | A cast made of material that will withstand the high temperatures of metal casting or soldering without disintegrating. Synonym: investment cast. (05 Mar 2000) |
