| 영문 | hormone | 한글 | 호르몬 |
|---|---|---|---|
| 설명 | 호르몬이란 특정한 내분비선에서 생성, 저장되어 있다가, 관류하는 혈액 중으로 분비된 다음 혈액에 실려 멀리 떨어져 있는 표적세포(호르몬이 작용을 나타내는 세포)에 이르러 그곳에서 특정한 기능을 발휘하는 물질을 말한다. 내분비샘이 아니더라도 어느 세포나 세포군에서 세포외액 중으로 분비된 다음 다른 세포에 가서 세포의 기능을 변동시키는 물질의 일부도 호르몬의 범주에 포함시키고 있으며 이들을 특별히 국소호르몬이라 부른다(예-아세틸콜린, 아드레날린, 콜레시스토키닌 등). 이에 비해서 특정 내분비샘에서 혈중으로 분비되는 진정한 의미의 호르몬들을 일반호르몬이라고 부른다. 호르몬을 흔히 3종의 무리로 분류를 하는데 아드레날린이나 thyroxine과 같이 아미노산의 유도체로 된 호르몬들(amine derivative), 많은 아미노산을 재료로 만들어졌거나 당단백으로 된 단백호르몬(peptide hormone), 그리고 콜레스테롤을 재료로 만들어진 지방호르몬(steroid hormone) 등으로 구분되며 이들은 대체로 종류에 따라 작용메커니즘을 달리하고 있다. |

| 영문 | luteinizing hormone(LH) | 한글 | 황체형성호르몬 |
|---|---|---|---|
| 설명 | 여성의 월경은 정해진 순서에 의해 일어나게 된다. 먼저 난포자극호르몬이 뇌에서 분비되어 여성의 난소를 자극하게 되면 난포가 자극받아 난포호르몬(에스트로젠)을 분비하게 되고 이것은 다시 되먹이기 메커니즘 의해 뇌에 작용을 하여 황체화호르몬이 뇌에서 분비되고 이것이 이른바 절정에 이르렀을 때, 난포에서 배란이 일어나게 된다. 이후 난포는 황체로 변하게 되며, 배란된 난자가 수정되지 아니하면, 황체는 황체호르몬(프로게스테론)을 분비한 뒤 퇴화되고 곧 이어 월경이 일어나게 된다. 이 일은 정상적인 대부분의 여성에서 28일을 주기로 일어나며, 대개 황체화호르몬 절정 이후 마지막은 14일로 일정하다고 한다. |

| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |

| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| accretionary growth | Growth by an increase of intercellular material. (05 Mar 2000) |
| appositional growth | Growth accomplished by the addition of new layers on those previously formed; e.g., the addition of lamellae in the formation of bone; it is the characteristic method of growth when rigid materials are involved. (05 Mar 2000) |
| auxetic growth | Growth by increase in the size of component cells. Synonym: intussusceptive growth. (05 Mar 2000) |
| bacterial growth | Growth of a bacterial culture either by increase in cell material or cell number. (05 Mar 2000) |
| B-cell differentiation/growth factors | Various substances, usually obtained from the supernatant of T-cell cultures, such as interleukin 4, 5, and 6. These substances are necessary for B-cell growth, maturation, and differentiation into plasma cells or B memory cells. (05 Mar 2000) |
| biphasic growth curve | <cell culture, microbiology> A particular type of growth curve seen in cultured microorganisms in which they have two exponential growth stages separated by a plateau phase. This double-hump curve is produced when the microbes are cultured using two carbon sources, one of which must be used up before the second can be used. (19 Jan 1998) |
| 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) |
| capon-comb-growth test | A test for androgenic activity, based upon the stimulation of comb growth in capons (castrated cockerels) or immature roosters. Synonym: capon-comb-growth test, cock's comb test. (05 Mar 2000) |
| radial growth phase | The early pattern of growth of cutaneous malignant melanoma, in which tumour cells spread laterally in the epidermis. (05 Mar 2000) |
| vascular endothelial growth factor | A growth factor that is responsible for the growth of blood vessels. (12 Dec 1998) |
| mammary derived growth inhibitor | Fatty acid binding protein that inhibits proliferation of mammary carcinoma cells. (18 Nov 1997) |
| 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) |
