|---|---|---|---|
| 설명 | 생물체 세포속에서 합성되고, 주로 세포내에서 진행되는 화학반응을 촉매하는 단백질로 시험관내에서도 같은 촉매작용을 한다. 이 효소는 인공적으로 만든 어떤 촉매제보다 그 특이성과 촉매작용이 탁월한 특별한 생체분자이다. 신진대사, 즉 세포내에서 일어나는 물질의 화학적 변환은 효소의 작용에 의해 매우 빠르고 원할하게 이루어진다. 이것은 효소의 촉매 효율이 높은 점과 효소의 기질 특이성 때문이다. 효소반응은 상온, 상압, 최적 pH 등 적절한 조건 아래에서 진행된다. 또 효소의 주체가 단백질이기 때문에 단백질을 변성시키는 열, 강산, 강알칼리, 유기용매 등에 의해 그 작용을 잃는다. 효소는 생체에 널리 분포하며, 복잡하고 다양한 대사반응을 촉매하기 때문에 종류도 많다. 앞서 말한 바와 같이 대부분의 효소는 세포내에 존재하지만, 혈액과 그외의 간질액에 들어 있기도 하고 소화효소류처럼 체외로 분비되는 것도 있다. |

|---|---|---|---|
| 설명 | 효소결합면역흡착제 검정법으로 번역되고 있다. 이 법은 항원(또는 항체)에 알칼리 포스파타아제 또는 페르옥시디아제 등의 산소를 결합시켜 두고 그 산소활성을 지표로 삼아 항원항체반응의 정도를 안 다음 여기에서 항원(또는 항체)의 양을 구하는 것이다. 이 법의 이점으로서 고감도, 조작의 간단함 및 방사선면역측정법처럼 방사성물질을 사용하지 않아도 된다는 점을 들 수 있다. 호르몬이나 면역글로불린의 정량법으로서 응용 되고 있으며 측정용 키트도 시판되고 이있다. |

|---|---|
| wandering organ | An organ with loose attachments, permitting its displacement. Synonym: floating organ, ptotic organ. (05 Mar 2000) |
| Weber's organ | A minute pouch in the prostate opening on the summit of the seminal colliculus, the analogue of the uterus and vagina in the female, being the remains of the fused caudal ends of the paramesonephric ducts. Synonym: utriculus prostaticus, masculine uterus, Morgagni's sinus, sinus pocularis, uterus masculinus, vagina masculina, vesica prostatica, Weber's organ. (05 Mar 2000) |
| multiple organ failure | A progressive condition usually characterised by combined failure of the lungs, liver, kidney, and clotting mechanisms, usually postinjury or postoperative. (12 Dec 1998) |
| Corti's organ | A prominent ridge of highly specialised epithelium in the floor of the cochlear duct overlying the basilar membrane of cochlea, containing one inner row and three outer rows of hair cells, or cells of Corti (the auditory receptor cells innervated by the cochlear nerve) supported by various columnar cells: the pillars of Corti, cells of Hensen, and cells of Claudius; the spiral organ is partly overhung by an awning-like shelf, the tectorial membrane, the free marginal zone of which is covered by a gelatinous substance in which the stereocilia of the outer hair cells are embedded. Synonym: organum spirale, acoustic papilla, Corti's organ. (05 Mar 2000) |
| critical organ | The organ or physiologic system that for a given source of radiation would first reach its legally defined maximum permissible radiation exposure as the dose of radiopharmaceutical is increased; e.g., the kidney is the critical organ when 197Hg-chlormerodrin is given. (05 Mar 2000) |
| ptotic organ | An organ with loose attachments, permitting its displacement. Synonym: floating organ, ptotic organ. (05 Mar 2000) |
| spiral organ | A prominent ridge of highly specialised epithelium in the floor of the cochlear duct overlying the basilar membrane of cochlea, containing one inner row and three outer rows of hair cells, or cells of Corti (the auditory receptor cells innervated by the cochlear nerve) supported by various columnar cells: the pillars of Corti, cells of Hensen, and cells of Claudius; the spiral organ is partly overhung by an awning-like shelf, the tectorial membrane, the free marginal zone of which is covered by a gelatinous substance in which the stereocilia of the outer hair cells are embedded.

| neuromast organ | A structure in fish consisting of a long groove or canal extending along each side of the trunk and tail and branching in the head region; the groove or tube is lined with neuroepithelial cells, some of which are in groups known as neuromasts; its function appears to be the detection of vibrations of low frequency. Synonym: neuromast organ. (05 Mar 2000) |
| neurotendinous organ | <cell biology, physiology> A proprioceptive sensory nerve ending embedded among the fibres of a tendon, often near the musculotendinous junction; it is compressed and activated by any increase of the tendon's tension, caused either by active contraction or passive stretch of the corresponding muscle. Synonym: neurotendinous organ, neurotendinous spindle. (05 Mar 2000) |

The root is attached to the descending portions of the pubic bone by the crura, the latter being the extremities of the corpora cavernosa and beneath them the corpus spongiosum, through which the urethra passes. The glans is covered with mucous membrane and ensheathed by the prepuce or foreskin. The penis is homologous with the clitoris in the female. (18 Nov 1997) |

| organ | 1. An instrument or medium by which some important action is performed, or an important end accomplished; as, legislatures, courts, armies, taxgatherers, etc, are organs of government. 2. <biology> A natural part or structure in an animal or a plant, capable of performing some special action (termed its function), which is essential to the life or well-being of the whole; as, the heart, lungs, etc, are organs of animals; the root, stem, foliage, etc, are organs of plants. In animals the organs are generally made up of several tissues, one of which usually predominates, and determines the principal function of the organ. Groups of organs constitute a system. See System. 3. A component part performing an essential office in the working of any complex machine; as, the cylinder, valves, crank, etc, are organs of the steam engine. 4. A medium of communication between one person or body and another; as, the secretary of state is the organ of communication between the government and a foreign power; a newspaper is the organ of its editor, or of a party, sect, etc. 5. [Cf. AS. Organ, fr. L. Organum. A wind instrument containing numerous pipes of various dimensions and kinds, which are filled with wind from a bellows, and played upon by means of keys similar to those of a piano, and sometimes by foot keys or pedals; formerly used in the plural, each pipe being considired an organ.
