| 영문 | beta human chorionic gonadotropin | 한글 | 베타 사람융모성 생식샘자극호르몬 |
|---|---|---|---|
| 설명 | 태반세포에서 만들어지는 호르몬. 기능은 임신의 초기에 황체(원래 난자를 싸고 있던 세포들이 배란이 일어나서 난자가 빠져나간 후 주머니 모양을 이룬 것. 임신초기에 임신의 유지에 필요한 호르몬을 생성한다)의 유지에 기여하고, 태아의 고환조직에서 남성호르몬이 분비되는 것을 촉진시킨다. 또 이것은 임신초기의 임산부의 소변에서 많은 양이 검출되므로 이것을 이용해서 임신의 여부를 손쉽게 조사할 수가 있다. |

| 영문 | beta ray | 한글 | 베타선 |
|---|---|---|---|
| 설명 | 방사성 원자핵이 β붕괴함에 따라 방출되는 방사선. 원자에 정상보다 많거나 적은 중성자나 양자를 가지고 있는 경우에는 원자가 안정되기 위하여 붕괴가 세가지 방법으로 생긴다. 이중 중성자가 하나의 전자를 내고 양성자가 되는 변화를 거치면서 나오는 전자선이다. 그 실체는 고속의 전자 또는 양전자이며 최대 에너지는 105-107eV. 투과력 및 이온화 작용은 α선과 γ선의 중간 정도이다. |

| adenoma, basophil | A small tumour of the anterior lobe of the pituitary gland whose cells stain with basic dyes. It may give rise to excessive secretion of acth, resulting in cushing's syndrome. (12 Dec 1998) |
|---|---|
| basophil | <haematology> Mammalian granulocyte with large heterochromatic basophilic granules that contain histamine bound to a protein and heparin like mucopolysaccharide matrix. They are not phagocytic. Very similar to mast cells though it is not clear whether they have common lineage. (18 Nov 1997) |
| basophil adenoma | <tumour> A tumour of the adenohypophysis in which the cell cytoplasm stains with basic dyes, often ACTH producing. (05 Mar 2000) |
| basophil cell of anterior lobe of hypophysis | beta cell of anterior lobe of hypophysis |
| basophil degranulation test | An in vitro test used in the diagnosis of allergies including drug hypersensitivity. The allergen is added to the patient's white blood cells and the subsequent histamine release is measured. (12 Dec 1998) |
| basophil granule | A granule that stains readily with a basic dye. (05 Mar 2000) |
| basophil substance | The material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Synonym: basophil substance, basophilic substance, chromophil substance, Nissl bodies, Nissl granules, substantia basophilia, tigroid bodies, tigroid substance. (05 Mar 2000) |
| tissue basophil | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |
| androst-5-ene-3 beta,17 beta-diol | <chemical> An adrenal-derived oestrogenic metabolite of dhea. Evidence exist for its use as an endocrine regulator of immune response. Pharmacological action: anabolic steroids. Chemical name: Androst-5-ene-3,17-diol, (3beta,17beta)- (12 Dec 1998) |
| beta-1,3-galactosyl-0-glycosyl-glycoprotein beta-1,3-N-acetylglucosaminyltransferase | <enzyme> Capable of adding a glcnac residue to g1cnacman(3)g1cnac; from mung bean seedlings Registry number: EC 2.4.1.146 Synonym: n-acetylglucosaminyltransferase II, gal3-(glcnac6)galnac-mucin (glcnac--gal)3-glcnactransferase (26 Jun 1999) |

| beta-n-acetylglucosaminylglycopeptide beta-1,4-galactosyltransferase | <enzyme> An enzyme that catalyses the transfer of galactose from udp-galactose to a specific glycoprotein receptor, 2-acetamido-2-deoxy-d-glucosyl-glycopeptide, during glycopeptide synthesis. Chemical name: UDPgalactose:N-acetyl-beta-D-glucosaminylglycopeptide beta-1,4-galactosyltransferase Registry number: EC 2.4.1.38 (12 Dec 1998) |
| beta, or beta-value | <radiobiology> Ratio of plasma kinetic pressure to magnetic-field pressure, proportional to the ratio of plasma kinetic energy density to magnetic field energy density. Beta is usually measured relative to the total, local field (loosely called beta toroidal), but sometimes the plasma pressure relative to only the poloidal component of the field (beta poloidal) or relative to some external field (like the maximum field at the magnetic coils) is more useful. There is also a normalised beta (beta_N) of interest when discussing the beta limit. (lots of help from Art Carlson with the above.) Because the cost of a reactor is strongly influenced by the strength of the magnetic field that must be provided, beta values are directly related to the economics of fusion power production. Beta is usually expressed as a percentage, with 5% generally believed to be the minimum value required for an economical fusion reactor. See: pressure, kinetic pressure, magnetic pressure, second stability. (09 Oct 1997) |
