| 설명 | 세포핵 속에 존재하며, 헤마톡실린 등의 염기성 색소로 염색이 되는 물질. 염색사나 염색체의 주성분이다. 세포핵 안에는 호염기성 물질로 DNA와 히스톤(핵단백질)의 복합체를 주성분으로 한다. 원래는 염기성 색소에 쉽게 염색된다는 의미에서 명명되었다. 세포주기에 따라 그 구조가 변한다. 전자현미경으로 전자밀도가 높은 부분은 기능이 낮고 전자밀도가 낮은 부분은 기능적으로 활성도가 높다. 퍼진염색질과 뭉친염색질로 나누기도 한다. 퍼진염색질은 이상 응축을 일으키지 않지만 유전자를 함유하고 있다. 이것에 비해 뭉친염색질은 이상응축을 나타내며, 퇴색반응으로 각 염색체에 특유한 줄무늬를 나타낸다. |

| vitelline reservoir | In cestodes and trematodes, a common chamber receiving vitelline (yolk) material from the two vitelline ducts; the yolk material then passes into the ootype to surround the ovum with nutritive vitelline granules that are enclosed by a characteristically formed eggshell. Synonym: vitelline reservoir. (05 Mar 2000) |

| Pecquet's reservoir | A dilated sac at the lower end of the thoracic duct into which the intestinal trunk and two lumbar lymphatic trunks open; it occurs inconstantly and when present is located posterior to the aorta on the anterior aspect of the bodies of the first and second lumbar vertebrae. Synonym: ampulla chyli, chyle cistern, chylocyst, Pecquet's cistern, Pecquet's reservoir, receptaculum chyli, receptaculum pecqueti. (05 Mar 2000) |
| reservoir | 1. <anatomy> A place or cavity for storage, for anatomical structures serving as a storage space for fluids. 2. <geography> A place where anything is kept in store; especially, a place where water is collected and kept for use when wanted, as to supply a fountain, a canal, or a city by means of aqueducts, or to drive a mill wheel, or the like. 3. <botany> A small intercellular space, often containing esin, essential oil, or some other secreted matter. Receiving reservoir, a principal reservoir into which an aqueduct or rising main delivers water, and from which a distributing reservoir draws its supply. 4. <microbiology> A reservoir host or reservoir of infection, an alternate or passive host or carrier that harbours pathogenic organisms, without injury to itself and serves as a source from which other individuals can be infected. Origin: F. Reservoir, LL. Reservatorium, from server = to reserve (27 Oct 1998) |
| reservoir bag | A collapsible reservoir from which gases are inhaled and into which gases may be exhaled during general anaesthesia or artificial ventilation. Synonym: reservoir bag. (05 Mar 2000) |
| reservoir host | The host of an infection in which the infectious agent multiplies and/or develops, and upon which the agent is dependent for survival in nature; the host essential for the maintenance of the infection during times when active transmission is not occurring. (05 Mar 2000) |
| reservoir of infection | Living or nonliving material in or on which an infectious agent multiplies and/or develops and is dependent for its survival in nature. (05 Mar 2000) |
| reservoir of spermatozoa | The site where spermatozoa are stored; the distal portion of the tail of the epididymis and the beginning of the ductus deferens. (05 Mar 2000) |
| reservoir, ommaya | A device implanted under the scalp and used to deliver anticancer drugs to the fluid surrounding the brain and spinal cord. (12 Dec 1998) |
| ommaya reservoir | <apparatus> A device with a fluid reservoir implanted under the scalp with a catheter to a ventricle. It allows for medication to be given directly to the CSF and into the brain. (16 Dec 1997) |
| Barr chromatin body | Condensed chromatin of the inactivated X chromosome in female mammals (Barr body). (18 Nov 1997) |
| chromatin | Stainable material of interphase nucleus consisting of nucleic acid and associated histone protein packed into nucleosomes. Euchromatin is loosely packed and accessible to RNA polymerases, whereas heterochromatin is highly condensed and probably transcriptionally inactive. (18 Nov 1997) |
| chromatin 3'-phosphatase-5'-hydroxy kinase | <enzyme> Hydrolyzes the 3'-phosphate end of a polynucleotide duplex followed by ATP-mediated phosphorylation of the 5'-oh end Registry number: EC 3.1.3.- Synonym: chromatin-phosphatase-hydroxykinase (26 Jun 1999) |
