| 설명 | 척추동물의 적혈구 속에 다량으로 들어있는 색소단백질. 철을 품는 포르피린 고리와 단백질의 일종(글로빈)으로 되어 있다. 철(Fe)에는 산소와 가역적으로 결합하는 능력이 있어, 생체 내에서는 산소를 운반하는 일을 한다. 혈색소 한 분자는 네 개의 폴리펩티드 사슬로 되어 있고, 각각의 폴리펩티드 사슬에는 한 개씩의 헴이 함유되어 있다. 따라서 혈색소 한 분자에는 철원자가 네 개 함유되고, 철원자 한 개에 대해 한 분자씩의 산소가 결합하므로, 혈색소 한 분자에는 산소 4분자가 결합한다. 혈색소는 산소압이 높은 허파나 아가미에서는 산소와 결합하고, 산소압이 낮은 조직에 이르면 산소를 유리한다. 더욱이 산소의 방출은 pH가 낮아짐에 따라 촉진되므로, 이산화탄소가 많고 pH가 낮은 말초조직에서는 산소를 보다 유리하기 쉽게 된다. 이산화탄소는 혈장 속에 녹아 허파에 운반되어 허파호흡으로 체외에 방출되면 pH는 다시 원상태로 돌아가고 혈색소는 다시 산소와 결합한다. 분자량 약 6,500의 색소단백질로 혈액 속에서의 함유량은 혈액 100 mL중의 그램수로 나타낸다. 정상치는 남자 16g/dL(14~18g/dL), 여자 14g/dL (12~16g/dL)이다. |

| hemoglobin | <cell biology, haematology> Four subunit globular oxygen carrying protein of the erythrocytes of vertebrates and some invertebrates. It is a conjugated protein containing four haem groups and globin. There are two alpha and two beta chains (very similar to myoglobin) in adult humans, the haem moiety (an iron containing substituted porphyrin) is firmly held in a nonpolar crevice in each peptide chain. There are four globin polypeptide chains, designated alpha, beta, gamma, delta in the adult. Each is composed of several hundred amino acids. (08 Mar 2000) |

| arrhythmias, slow | Abnormally slow heart rhythms, medically termed bradycardia. (12 Dec 1998) |
| slow | To go slower; often with up; as, the train slowed up before crossing the bridge. 1. Moving a short space in a relatively long time; not swift; not quick in motion; not rapid; moderate; deliberate; as, a slow stream; a slow motion. 2. Not happening in a short time; gradual; late. "These changes in the heavens, though slow, produced Like change on sea and land, sidereal blast." (Milton) 3. Not ready; not prompt or quick; dilatory; sluggish; as, slow of speech, and slow of tongue. "Fixed on defense, the Trojans are not slow To guard their shore from an expected foe." (Dryden) 4. Not hasty; not precipitate; acting with deliberation; tardy; inactive. "He that is slow to wrath is of great understanding." (Prov. Xiv. 29) 5. Behind in time; indicating a time earlier than the true time; as, the clock or watch is slow. 6. Not advancing or improving rapidly; as, the slow growth of arts and sciences. 7. Heavy in wit; not alert, prompt, or spirited; wearisome; dull. Slow is often used in the formation of compounds for the most part self-explaining; as, slow-gaited, slow-paced, slow-sighted, slow-winged, and the like. Slow coach, a slow person. See def.7, above. <zoology> Slow lemur, or Slow loris, an East Indian nocturnal lemurine animal (Nycticebus tardigradus) about the size of a small cat; so called from its slow and deliberate movements. It has very large round eyes and is without a tail. Called also bashful Billy. Slow match. See Match. Synonym: Dilatory, late, lingering, tardy, sluggish, dull, inactive. Slow, Tardy, Dilatory. Slow is the wider term, denoting either a want of rapid motion or inertness of intellect. Dilatory signifies a proneness to defer, a habit of delaying the performance of what we know must be done. Tardy denotes the habit of being behind hand; as, tardy in making up one's acounts. Origin: OE. Slow, slaw, AS. Slaw; akin to OS. Slu blunt, dull, D. Sleeuw, slee, sour, OHG. Slo blunt, dull, Icel. Slr, slr, Dan. Slov, Sw. Slo. Cf. Sloe, and Sloth. Source: Websters Dictionary (01 Mar 1998) |

| slow combustion | See: decay. Spontaneous combustion, the ignition of a mass of material by heat developed within it by the oxidation of the substances composing it without external ignition. (05 Mar 2000) |
| slow fever | A continued fever of long duration. (05 Mar 2000) |
| slow muscle | <physiology> Striated muscle used for long term activity (e.g. Postural support). Depend therefore on oxidative metabolism and have many mitochondria and abundant myoglobin. (18 Nov 1997) |

| slow ray | <microscopy> The slower of the two rays created by a crystal or fibre and the one that travels the path of higher refractive index. (05 Aug 1998) |
| slow-reacting factor of anaphylaxis | Slow-reacting substance of anaphylaxis (SRS-A), a leukotriene of low molecular weight which is released in anaphylactic shock and produces slower and more prolonged contraction of muscle than does histamine; it is active in the presence of antihistamines (but not epinephrine) and seems not to occur preformed in mast cells, but as a result of an antigen-antibody reaction on the granules. Compare: peptidyl leukotrienes. Synonym: slow-reacting factor of anaphylaxis. (05 Mar 2000) |

| slow reacting substance of anaphylaxis | <immunology> Potent bronchoconstrictor and inflammatory agent released by mast cells, an important mediator of allergic bronchial asthma. A mixture of three leukotrienes (LTC4 mainly, LTD4 and LTE4) (18 Nov 1997) |
| slow scan | <microscopy> A system of video scanning in which the time used to read each line has been increased in comparison to standard video. The bandwidth needed to faithfully transmit or record the signal is reduced in inverse ratio to the scanning time. Slow scan allows the video signal to be transmitted over a telephone line, or line scans to be registered on a chart recorder. (19 Jan 1998) |
| slow virus | 1. <virology> Specifically one of the Lentivirinae 2. Any virus causing a disease that has a very slow onset. Diseases such as sub acute spongiform encephalopathy, Aleutian disease of mink, scrapie, kuru and Creutzfeldt Jacob disease may be caused by slow viruses. See: prion. (18 Nov 1997) |
| slow virus disease | A disease that follows a slow, progressive course spanning months to years, frequently involving the central nervous system, and ultimately leading to death, such as visna and maedi of sheep, caused by viruses of the subfamily Lentivirinae (family Retroviridae), and subacute sclerosing panencephalitis, seemingly caused by the measles virus; spongiform encephalopathies including kuru of man, scrapie of sheep, and transmissible encephalopathy of mink may also be classified under slow virus disease but their respective aetiologic agents have not been adequately characterised.
