|---|---|---|---|
| 설명 | 신생아를 포함해 출생 후 1년까지의 어린이를 말하며 이 기간을 영아기라 부른다. 신체발육 및 운동기능의 발달이 매우 활발한 시기이다. 이 시기는 신생아 때부터 계속해서 환경에 적응해 가는 중요한 시기이다. 젖니가 나오며 면역기능의 활성화, 반사의 소실과 수의운동의 발달, 감각(시각, 청각, 촉각) 기능의 발달, 체중과 키의 증가를 확인할 수 있다. 체중은 3개월에 2배, 1년엔 3배가 되며, 키는 1년에 약 27cm 자란다. |

| 영문 | sudden infant death syndrome | 한글 | 영아급사증후군 |
|---|---|---|---|
| 설명 | 한 살 이하의 건강한 아기가 아무런 조짐이나 원인 없이 갑자기 사망했을 경우에 내리는 진단이다. 이 증후군은 생후 1~4개월 사이에 가장 많이 발생하며, 대부분 밤 10시에서 오전 10시 사이에 발생한다. 조산하거나 부모가 흡연자일 경우, 20세 이하 산모의 초산, 임신전 건강관리에 소홀한 산모에게서 태어난 영아에게서 많이 발생한다. 이 증후군으로 사망한 영아의 형제일 경우 일반적인 영아보다 걸릴 확률이 높은 것으로 알려져 있다. |

| myosin heavy chain | <protein> See myosin: do not confuse with heavy meromyosin which is a subfragment of the heavy chain of myosin II. (18 Nov 1997) |
|---|---|
| myosin heavy chains | The heavy chains of the muscle protein myosin. Each molecule of myosin is composed of two heavy chains and two pairs of light chains. The heavy chains have a molecular weight of about 230 kD and each heavy chain is associated with a dissimilar pair of light chains. (devlin, textbook of biochemistry: with clinical correlations, 3rd ed, p957) (12 Dec 1998) |
| heavy | 1. Heaved or lifted with labour; not light; weighty; ponderous; as, a heavy stone; hence, sometimes, large in extent, quantity, or effects; as, a heavy fall of rain or snow; a heavy failure; heavy business transactions, etc.; often implying strength; as, a heavy barrier; also, difficult to move; as, a heavy draught. 2. Not easy to bear; burdensome; oppressive; hard to endure or accomplish; hence, grievous, afflictive; as, heavy yokes, expenses, undertakings, trials, news, etc. "The hand of the Lord was heavy upon them of Ashdod." (1 Sam. V. 6) "The king himself hath a heavy reckoning to make." (Shak) "Sent hither to impart the heavy news." (Wordsworth) "Trust him not in matter of heavy consequence." (Shak) 3. Laden with that which is weighty; encumbered; burdened; bowed down, either with an actual burden, or with care, grief, pain, disappointment. "The heavy [sorrowing] nobles all in council were." (Chapman) "A light wife doth make a heavy husband." (Shak) 4. Slow; sluggish; inactive; or lifeless, dull, inanimate, stupid; as, a heavy gait, looks, manners, style, and the like; a heavy writer or book. "Whilst the heavy plowman snores." (Shak) "Of a heavy, dull, degenerate mind." (Dryden) "Neither [is] his ear heavy, that it can not hear." (Is. Lix. 1) 5. Strong; violent; forcible; as, a heavy sea, storm, cannonade, and the like. 6. Loud; deep; said of sound; as, heavy thunder. "But, hark! that heavy sound breaks in once more." (Byron) 7. Dark with clouds, or ready to rain; gloomy; said of the sky. 8. Impeding motion; cloggy; clayey; said of earth; as, a heavy road, soil, and the like. 9. Not raised or made light; as, heavy bread. 10. Not agreeable to, or suitable for, the stomach; not easily digested; said of food. 11. Having much body or strength; said of wines, or other liquors. 12. With child; pregnant. Heavy artillery. <chemistry> See Metal. Heavy weight, in wrestling, boxing, etc, a term applied to the heaviest of the classes into which contestants are divided. Cf. Feather weight, under Feather. Heavy is used in composition to form many words which need no special explanation; as, heavy-built, heavy-browed, heavy-gaited, etc. Origin: OE. Hevi, AS. Hefig, fr. Hebban to lift, heave; akin to OHG. Hebig, hevig, Icel. Hofigr, hofugr. See Heave. Source: Websters Dictionary (01 Mar 1998) |
| heavy chain | <protein> In general, the larger polypeptide in a multimeric protein. Thus the immunoglobulin heavy chain is of 50 kD, the light chain of 22 kD, whereas in myosin the heavy chain is very much larger (220 kD) than the light chains (~20 kD). (18 Nov 1997) |
| heavy chain disease | A disorder of immunoglobulin synthesis in which large quantities of abnormal heavy chains are excreted in the urine. The amino acid sequences of the n- (amino-) terminal regions of these chains are normal, but they have a deletion extending from part of the variable domain through the first domain of the constant region, so that they cannot form cross-links to the light chains. The defect arises through faulty coupling of the variable (v) and constant (c) region genes. (12 Dec 1998) |
| heavy hydrogen | <radiobiology> Somewhat informal alternative name for deuterium. See: deuterium. (10 Jan 1998) |
| Heavy Ion Beams | <radiobiology> Particle beams using heavy (as opposed to light) ions. These can be used for inertial confinement fusion research. (10 Jan 1998) |
| heavy liquid petrolatum | <chemical> A mixture of liquid hydrocarbons obtained from petroleum. It is used as laxative, lubricant, ointment base, and emollient. Pharmacological action: cathartic, emollients, ointment bases. Chemical name: Hydrocarbon oils (12 Dec 1998) |
| heavy metal | A metal with a high specific gravity, typically larger than 5; e.g., Fe, Co, Cu, Mn, Mo, Zn, V. (05 Mar 2000) |
| heavy metal neuropathy | Peripheral nervous system disorders attributed to intoxication of one of the heavy metals: arsenic, gold, lead, mercury, platinum and thallium. (05 Mar 2000) |

| heavy water | most commonly used by cell biologists to stabilise microtubules. (18 Nov 1997) |
| immunoglobulins, heavy-chain | Major components of immunoglobulin molecules. They are the larger of the two types of polypeptide chains responsible for the biological and immunological properties of the different immunoglobulins. They differ according to the class of ig from which they were isolated, contain 450 to 600 amino acid residues per chain, and have molecular weights of 51-72 kD. One ig molecule comprises two heavy and two light chains. (12 Dec 1998) |
