|---|---|---|---|
| 설명 | 어떤 물질계나 구조에 액체나 기체 등의 확산이 있는 경우에 그 구조가 확산성 물질분자의 통과나 침입을 허용하는 성질. 생물학적으로는 특히 세포막을 비롯한 여러 생체의 막구조가 가지는 투과성이 중요하다. 이 생체막의 대부분은 용매나 일부의 한정된 용질 분자만을 통과시키기 쉬운 반투막을 가지며, 이 성질은 그 생체막이 살아 있는 상태에서만 유지된다. 생체막의 투과성은 그 막을 지나서 일어나는 여러 가지 물질의 이동에 깊은 관계가 있다. 삼투압에 의한 단순한 확장에 주로 기인하는 수동적인 경우로부터 염류-포도당-아미노산 등의 흡수 때 에너지를 필요로 하는 능동적 수송까지 여러 가지가 있다. 또한 분비-흡수-배출, 막의 흥분성 등 수많은 중요한 생리현상의 요인이다. |

| dentin permeability | The property of dentin that permits passage of light, heat, cold, and chemical substances. It does not include penetration by microorganisms. (12 Dec 1998) |

| capillary permeability | Property of blood capillary walls that allows for the selective exchange of substances. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (tight junctions) which may limit large molecule movement. (12 Dec 1998) |

| capillary permeability factor | A mixture of bioflavonoids extracted from plants (especially citrus fruits). It reduces the permeability and fragility of capillaries and is useful in the treatment of certain cases of purpura that are resistant to vitamin C therapy. See: hesperidin, quercetin, rutin. Synonym: capillary permeability factor, citrin, permeability vitamin. (05 Mar 2000) |
| cell membrane permeability | A quality of cell membranes which permits the passage of solvents and solutes into and out of cells. (12 Dec 1998) |
| permeability | The property or state of being permeable. (18 Nov 1997) |
| permeability coefficient | A coefficient associated with simple diffusion through a membrane that is proportional to the partition coefficient and the diffusion coefficient and inversely proportional to membrane thickness. (05 Mar 2000) |
| permeability constant | A measure of the ease with which an ion can cross a unit area of membrane driven by a 1.0 m difference in concentration; usually expressed in centimeters per second. Compare: permeability coefficient. (05 Mar 2000) |
| permeability theory of narcosis | That the permeability of the cell membrane is decreased by narcotic concentrations of aliphatic and other central nervous system depressants. (05 Mar 2000) |
| permeability vitamin | A mixture of bioflavonoids extracted from plants (especially citrus fruits). It reduces the permeability and fragility of capillaries and is useful in the treatment of certain cases of purpura that are resistant to vitamin C therapy. See: hesperidin, quercetin, rutin. Synonym: capillary permeability factor, citrin, permeability vitamin. (05 Mar 2000) |
| soil permeability | The ease with which gases, liquids or plant roots penetrate or pass through a layer of soil. (09 Oct 1997) |
| dental enamel permeability | <dentistry> The property of dental enamel to permit passage of light, heat, gases, liquids, metabolites, mineral ions and other substances. It does not include the penetration of the dental enamel by microorganisms. (12 Dec 1998) |
| Duran-Reynals permeability factor | <enzyme> Enzyme that degrades hyaluronic acid, found in lysosomes. (18 Nov 1997) |
| lymph node permeability factor | A substance, released by lymphocytes when stimulated or damaged, that increases capillary permeability and the accumulation of mononuclear cells. (05 Mar 2000) |
| vascular dentin | Dentin in which the primitive capillaries have remained uncalcified and so are wide enough to give passage to the formed elements of the blood. Synonym: vascular dentin. (05 Mar 2000) |
| reparative dentin | Morphologically irregular dentin formed in response to an irritant. Synonym: irregular dentin, irritation dentin, reparative dentin. (05 Mar 2000) |
| peritubular dentin | An electron-dense layer of dentin observed adjacent to the odontoblastic process. (05 Mar 2000) |
