|---|---|---|---|
| 설명 | 뇌와 척수에는 혈류로부터 어떤 물질이 유입되는 것을 막는 장벽이다. 이것은 뇌와 척수에 존재하는 모세혈관의 투과성이 비교적 다른 모세혈관의 투과성보다 떨어지기 때문이다. |

|---|---|---|---|
| 설명 | 혈액으로부터 뇌로는 지질용해성이 높은 약물밖에 이행되지 않는다. 수용성의 약물을 뇌로 이행되지 않게 하고 있는 것이 혈액뇌장벽이며 뇌의 모세혈관 내피세포, 모세혈관 주위의 세포가 장벽이 되고 있다. 물질교환은 수동확산에 의해 이루어지지만, 뇌의 생리적 활동에 필요한 물질은 이온형이라도 담체를 통해 이행된다. |

| heterocyclic compounds with 4 or more rings | A class of organic compounds containing four or more ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic. (12 Dec 1998) |
|---|---|
| Donders' rings | An obsolete term for the iridescent ring's or haloes observed by a cloudy cornea due to acute glaucoma. (05 Mar 2000) |
| oesophageal webs and rings | <radiology> Congenital web, web secondary to bullous disease, cervical web, Plummer-Vinson (Patterson-Kelly) syndrome, mucosal (Schatzki) ring (12 Dec 1998) |
| Liesegang rings | Coloured ring's of precipitated silver chromate formed when a drop of concentrated silver nitrate is added to the surface of a gel (such as gelatin, agar, or silica gel) containing potassium dichromate. (05 Mar 2000) |
| convex | Applied to a surface that is evenly curved outward, the segment of a sphere. Origin: L. Convexus, vaulted, arched, convex, fr. Con-veho, to bring together (05 Mar 2000) |
| convex lens | A converging lens. Synonym: plus lens. (05 Mar 2000) |
| convex mirror | A spherical reflecting surface that constitutes a segment of the exterior of a sphere. (05 Mar 2000) |
| high convex | The segment of a sphere of short radius. (05 Mar 2000) |
| double convex lens | A lens with both surfaces convex. Synonym: convexoconvex lens, double convex lens. (05 Mar 2000) |
| low convex | The segment of a sphere of long radius. (05 Mar 2000) |
| barrier | An obstruction. (18 Nov 1997) |
| barrier contraceptive | A mechanical device designed to prevent spermatozoa from penetrating the cervical os; usually used in combination with a spermicidal agent, i.e., vaginal diaphragm. (05 Mar 2000) |
| blood-air barrier | The barrier between capillary blood and alveolar air comprising the alveolar epithelium and capillary endothelium with their adherent basement membranes and epithelial cell cytoplasm. Gaseous exchange occurs across this membrane. (12 Dec 1998) |
| blood-aqueous barrier | The anatomical mechanism that prevents exchange of materials between the chambers of the eye and the blood. The tight junctions of the nonpigmented epithelium of the ciliary body, the junctions of the iris tissues, and iris blood vessels constitute the blood-aqueous barrier. Lipid-soluble substances such as oxygen and carbon dioxide penetrate the barrier at a high rate. Sodium, larger water-soluble ions, proteins, and other large and medium-sized molecules are restricted. (12 Dec 1998) |
| blood-brain barrier | <pharmacology, physiology> A protective barrier formed by the blood vessels and glia of the brain. It prevents some substances in the blood from entering brain tissue. The blood vessels of the brain (and the retina) are much more impermeable to large molecules (like antibodies) than blood vessels elsewhere in the body. This has important implications for the ability of the organism to mount an immune response in these tissues, although the basis for the difference in endothelial permeability is not well understood.
