| 영문 | growth hormone | 한글 | 성장호르몬 |
|---|---|---|---|
| 설명 | 뇌하수체 전엽에서 분비되는 호르몬중 하나로서 시상하부의 성장호르몬방출 호르몬에 의해 분비가 자극되며 소마토스타틴(somatostatin: 이자에서 분비되며, 성장호르몬에 반대되는 작용을 함)에 의해 분비가 억제된다. 성장 호르몬 방출 호르몬은 도파민(dopamine)으로 알려져 있다. 성장 호르몬은 세포의 성장을 촉진시키며 특히 골의 성장을 자극하는데 그 작용은 직접 세포에 작용하는 것이 아니라 간과 근육에 작용하여 그곳에서 소마토메딘을 생성하며 이 소마토메딘이 세포의 성장을 촉진시킨다. 한편 성장 호르몬은 성장에 필요한 단백질 합성을 항진시키고 에너지는 지방을 이용하여 얻게하므로 지방이용호르몬이라고도 불린다. 성장 호르몬이 과다 분비되면 거인증, 말단비대증이 유발되며 성장 호르몬이 결핍되면 성장부진이 온다. |

| 영문 | risk factor | 한글 | 위험인자 |
|---|---|---|---|
| 설명 | 국제방사선방호위원회(ICRP)가 1977년 권고에서 방사선방호의 목적으로 채택한 지수로, 단위선량(1 Sv)당 확률적 영향의 발생확률을 추정하여 나타낸 것이다. 생식선 선량에 대한 유전적영향의 발생률(4×10－3/Sv)이나 적색골수선량에 대한 백혈병 발생률(2×10－3/Sv)등 외에 뼈, 허파, 갑상샘, 젖샘, 기타 조직의 위험지수를 측정하여, 확률적 영향의 전신에 있어서 치사위험지수의 합계를 16.5×10－3/Sv로 하였다. 그후 ICRP는 1990년 권고에서 대상이 되는 조직과 장기를 추가하고, 수치 개정을 하면서 명칭도 각목적확률지수라고하였다. 이 권고에 의하면, 치사적 확률적 영향의 확률지수의 합계는, 일반인에 있어 60.0×10－3/Sv이다. |

| 영문 | sensory nerve | 한글 | 감각신경 |
|---|---|---|---|
| 설명 | 감각세포가 받은 자극을 중추신경에 전달하는 신경. 눈이나 피부 등에 있는 감각기가 외부로부터 자극을 받으면 감각신경을 거쳐 척수와 대뇌겉질까지 감각이 전달된다. 이와 같이 외부로부터 내부를 향해 전달되는 감각신경은 구심성 신경계통이며, 원심성 운동신경계통 및 자율신경계통에 필적하는 말초신경의 하나이다. 이 감각신경에는 후각신경(뇌신경Ⅰ)-시각신경(뇌신경Ⅱ)-눈돌림신경(뇌신경Ⅲ)-삼차신경(뇌신경Ⅴ)-얼굴신경(뇌신경Ⅶ)-청각신경(뇌신경Ⅷ)-혀인두신경(뇌신경Ⅸ)-미주신경(뇌신경Ⅹ) 및 척수신경이 있다. 감각신경 중 미주신경을 제외하면 모두 두부에 분포되어 있고, 후각신경-시각신경-청각신경의 세가지는 특히 분화된 감각상피를 지배한다. 혀인두신경은 미각의 말단장치와 그 밖의 부분에 연결되고 미주신경은 흉강과 복강의 기관에 분포되어 구심성 충격을 중추에 전달하며 삼차신경은 척수의 각 마디에 있는 신경에 해당하여(머리의 피부-점막 등의 표면감각과 심부감각을 관장한다. 척수의 감각신경계통에도 피부와 심부, 내장의 분포에 따른 구별이 있다. |

| receptors, nerve growth factor | Cell surface receptors that bind nerve growth factor (ngf) and trigger intracellular changes influencing the behaviour of cells. Nerve growth factor receptors mediate the effects of nerve growth factor on the survival and growth of neurons. (12 Dec 1998) |
|---|
| receptors, epidermal growth factor-urogastrone | Glycoproteins of about 170 kD that have protein kinase activity and span the plasma membranes of growing cells, including tumours. They are activated by the binding of epidermal growth factor-urogastrone which then initiates DNA and protein synthesis. They are not found on mitotically quiescent cells except in the stomach where they control the synthesis and release of digestive enzymes and gastric acid. Transforming growth factor alpha also binds to and activates these receptors. (12 Dec 1998) |
|---|---|
| receptors, fibroblast growth factor | Specific molecular sites or structures on cell membranes that react with fibroblast growth factors (both the basic and acidic forms), their analogs, or their antagonists to elicit or to inhibit the specific response of the cell to these factors. These receptors frequently possess tyrosine kinase activity. (12 Dec 1998) |
| receptors, growth factor | Cell surface receptors that bind growth or trophic factors with high affinity, triggering intracellular responses which influence the growth, differentiation, or survival of cells. (12 Dec 1998) |
| receptors, insulin-like-growth factor I | Specific proteins on or in cells to which insulin-like growth factor I (somatomedin c) binds and thereby modifies the function of the cells. These receptors contain transmembrane and cytosolic domains, bind igf-I preferentially, and have high-affinity sites for igf-II. The alpha-subunit has a mw of 130 kD and the beta subunit possesses tyrosine kinase activity. (12 Dec 1998) |
| receptors, insulin-like-growth-factor II | Specific proteins on or in cells to which insulin-like growth factor II and mannose-6-phosphate bind and thereby modify the function of the cells. These receptors have a mw of 250 kD and possess no tyrosine kinase activity. (12 Dec 1998) |
| receptors, platelet-derived growth factor | Specific molecular sites or structures on cell membranes that react with platelet-derived growth factor, its analogs, or antagonists, to elicit or to inhibit the specific response of the cell to this factor. Pdgf binds with different affinities and specificities to two structurally related receptors, the alpha-receptor and the beta-receptor. Both of these receptors are transmembrane proteins with an intracellular, ligand-stimulatable protein kinase domain. (12 Dec 1998) |
| receptors, transforming growth factor beta | Cell-surface proteins that bind transforming growth factor beta and trigger changes influencing the behaviour of cells. Two types of transforming growth factor receptors have been recognised. They differ in affinity for different members of the transforming growth factor beta family and in cellular mechanisms of action. Transforming growth factor alpha binds to the same receptors as epidermal growth factor (see receptors, epidermal growth factor-urogastrone). (12 Dec 1998) |
| nerve growth factor | <growth factor> A peptide (13.26 kD) of 118 amino acids (usually dimeric) with both chemotropic and chemotrophic properties for sympathetic and sensory neurons. Found in a variety of peripheral tissues, nerve growth factor attracts neurites to the tissues by chemotropism, where they form synapses. The successful neurons are then protected from neuronal death by continuing supplies of nerve growth factor. It is also found at exceptionally high levels in snake venom and male mouse submaxillary salivary glands, from which it is commercially extracted. Nerve growth factor was the first of a family of nerve tropic factors to be discovered. Amino acids 1-81 show homology with proinsulin. Besides its peripheral actions, nerve growth factor selectively enhances the growth of cholinergic neurons that project to the forebrain and that degenerate in Alzheimer's disease. Acronym: NGF (18 Nov 1997) |
| nerve growth factor antiserum | An antiserum containing antibodies against nerve growth factor; when injected into newborn animals the majority of sympathetic ganglion cells are permanently destroyed, resulting in hypoinnervation of peripheral tissues. Synonym: NGF antiserum. (05 Mar 2000) |
| brain-derived growth factor | <growth factor> Small basic protein purified from pig brain, a member of the family of neurotrophic factors that also includes Nerve Growth Factor and neurotrophin 3. In contrast to nerve growth factor, brain-derived neurotrophic factor is predominanantly (though not exclusively) localised in the CNS. It supports the survival of primary sensory neurons originating from the neural crest and ectodermal placodes that are not responsive to NGF. In the brain brain-derived neurotrophic factor has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. Acronym: BDGF (12 Dec 1998) |
| vascular endothelial growth factor | A growth factor that is responsible for the growth of blood vessels. (12 Dec 1998) |
| growth factor | <biochemistry> A complex family of polypeptide hormones or biological factors that are produced by the body to control growth, division and maturation of blood cells by the bone marrow. They regulate the division and proliferation of cells and influence the growth rate of some cancers. These factors occur naturally but some can be synthesised using molecular biology techniques and are used clinically to stimulate normal white cell production following chemotherapy or bone marrow transplantation. Examples include epidermal growth factor, platelet-derived growth factor, fibroblast growth factor. Insulin and somatomedin are also growth factors, the status of nerve growth factor is more uncertain. Perturbation of growth factor production or of the response to growth factor is important in neoplastic transformation. (29 Sep 1997) |
| growth hormone-releasing factor | <endocrinology> Peptide hormone related to the glucagon family, released from the pituitary, acts on the adenohypophysis to release growth hormone. Synonym: somatoliberin, growth hormone-releasing factor. (20 Sep 2002) |
| platelet-derived growth factor | <growth factor> The major mitogen in serum for growth in culture of cells of connective tissue origin. It consists of 2 different but homologous polypeptides A and B (~30,000 D) linked by disulphide bonds. Believed to play a role in wound healing. It is carried in the alpha-granules of platelets and is released when platelets adhere to traumatised tissues. Connective tissue cells near the traumatised region respond by initiating the process of replication. The B chain is almost identical in sequence to p28sis, the transforming protein of simian sarcoma virus, that can transform only those cells that express receptors for platelet derived growth factor, suggesting that transformation is caused by autocrine stimulation. The receptor is a tyrosine kinase. Acronym: PDGF (12 Dec 1998) |
| sarcoma growth factor | <growth factor> Polypeptide released by sarcoma cells that promotes the growth of cells by binding to a cell surface receptor, the sarcoma cell is therefore self sufficient and independent of normal growth control. See: growth factors. The name is no longer commonly used. (18 Nov 1997) |
