|---|---|---|---|
| 설명 | 의지작용 및 의식이 부분적으로 또는 완전히 정지되고 신체적 기능이 부분적으로 정지되는 몸과 마음의 상태. 수면은 입면기, 가벼운 수면기, 깊은 수면기, 렘수면기의 4상으로 나뉘어 있다. 깊은 수면에서 렘수면까지의 주기를 수면주기라고 하며 약 90분의 주기로 하루에 4~5회 되풀이된다. 수면의 주기는 뇌내의 수면을 일으키는 기구와 각성을 일으키는 기구가 번갈아 작동해서 형성되고 있다. 아침에 눈을 떠서 밤에 잠든다는 기본적인 일주기 리듬은 시상하부의 시각교차위핵에 의해서 억제되고 있다. 수면시간은 신생아에서 약 15시간이 나 있으나 성인에서 약 8시간, 노인이 되면 약 6시간 정도이다. 렘수면은 신생아에서 약 8시간이나 되지만 출생 후 2년째부터 급격히 감소한다. 수면량은 생쥐 등의 산소소비량이 많은 동물일수록 길고 코끼리와 같은 적은 동물일수록 짧다. 수면은 에너지소비량의 저하나 정상정신상태의 유지에도 관여한다고 생각되고 있다. |

| 설명 | 일반적으로, 생체나 생체 물질이 그 기능을 활발하게 나타내게 되는 것, 예를 들면 ① 촉매 등에서, 그 표면 상태의 변화나, 다른 물질의 첨가 등에 의하여, 그 기능이 현저하게 높아지는 것. ② 효소전구체의 활성화로서 효소작용을 가지지 않는 효소 전구체가 활성있는 효소로 변화는 것. 또 황화수소나 시안화수소산 등으로 파파인이 활성화되는 경우도 있다. |

| activation | <radiobiology> Activation occurs when a particle interacts with an atomic nucleus, shifting the nucleus into an unstable state, and causing it to become radioactive. In fusion research, where deuterium-tritium is a common fuel mixture, the neutron released when (D + T) combine to form (4He + n) can activate the reactor structure. In this case the 4He is inert, the neutron sticks to another nucleus, and the neutron + nucleus reaction creates an actvation product. Sometimes called radioactivation. See: activation product, activation analysis. (09 Oct 1997) |
|---|---|
| activation analysis | <radiobiology> Method for identifying and measuring chemical elements in a sample of material. Sample is first made radioactive by bombardment with neutrons, charged particles, or gamma rays. Newly formed radioactive atoms in the sample then give off characteristic radiations (such as gamma rays) that tell what kinds of atoms are present, and how many. (09 Oct 1997) |
| activation energy | <chemistry> The amount of energy (expressed in joules) that is needed to convert all the molecules in one mole of a reacting substance from a ground state to the transition state. (06 May 1997) |
| activation product | <radiobiology> The unstable nucleus formed when activation occurs. (See activation above.) (09 Oct 1997) |
| amino acid activation | The first step of protein synthesis, whereby an amino acid reacts with adenosine triphosphate in the presence of aminoacyl RNA synthetase to produce an amino acid adenylate, which provides the energy necessary for the attachment of the amino acid to a specific transfer RNA molecule. (12 Dec 1998) |
| macrophage activation | The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (maf) and the macrophage migration-inhibitory factor (mmif), immune complexes, c3b, and various peptides, polysaccharides, and immunologic adjuvants. (12 Dec 1998) |
| gene activation | The process of activation of a gene so that it is expressed at a particular time. This process is crucial in growth and development. (05 Mar 2000) |
| Gibbs energy of activation | The Gibbs energy that must be added to that already possessed by a molecule or molecules in order to initiate a reaction. (05 Mar 2000) |
| virus activation | The mechanism by which latent viruses, such as genetically transmitted tumour viruses or prophages of lysogenic bacteria, are induced to replicate and are released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell lipopolysaccharides, glucocorticoid hormones, halogenated pyrimidines, ionizing radiation, ultraviolet light, and superinfecting viruses. (12 Dec 1998) |
| cis activation | <molecular biology> Activation of a gene by an activator located on the same chromosome i.e. Not by a diffusible product. (18 Nov 1997) |
| complement activation | The sequential activation of serum components c1 through c9, initiated by an erythrocyte-antibody complex or by microbial polysaccharides and properdin, and producing an inflammatory response. (12 Dec 1998) |
| platelet activation | A series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable haemostatic plug. (12 Dec 1998) |
| neutron activation analysis | Activation analysis in which the specimen is bombarded with neutrons. Identification is made by measuring the resulting radioisotopes. (12 Dec 1998) |
| neutrophil activation | The process in which the neutrophil is stimulated by diverse substances, resulting in degranulation and/or generation of reactive oxygen products, and culminating in the destruction of invading pathogens. The stimulatory substances, including opsonised particles, immune complexes, and chemotactic factors, bind to specific cell-surface receptors on the neutrophil. (12 Dec 1998) |
| EEG activation | The low voltage, fast pattern of attentive wakefulness. (05 Mar 2000) |
