| 영문 | blood-brain barrier(BBB) | 한글 | 혈뇌장벽 |
|---|---|---|---|
| 설명 | 뇌와 척수에는 혈류로부터 어떤 물질이 유입되는 것을 막는 장벽이다. 이것은 뇌와 척수에 존재하는 모세혈관의 투과성이 비교적 다른 모세혈관의 투과성보다 떨어지기 때문이다. |

| 영문 | blood-brain barrier | 한글 | 혈액뇌장벽 |
|---|---|---|---|
| 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. |

| 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. (16 Dec 1997) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| blood-retinal barrier | Specialised nonfenestrated tightly-joined endothelial cells that form a transport barrier for certain substances between the retinal capillaries and the retinal tissue. (12 Dec 1998) |
| blood-testis barrier | The membrane in the testis that separates sperm from the bloodstream. (09 Oct 1997) |
| placental barrier | The semipermeable layer of foetal tissue separating the maternal from the foetal blood in the placenta; composed of: 1) endothelium of the foetal vessels in the chorionic villi, 2) stromata of the villi, 3) cytotrophoblast (negligible after the fifth month of gestation), and 4) syncytial trophoblast covering the villi; the placental membrane acts as a selective membrane regulating passage of substances from the maternal to the foetal blood. Synonym: placental barrier. (05 Mar 2000) |
| incest barrier | In psychoanalysis, the learning or internalization of parental and social prohibitions against incest. (05 Mar 2000) |
| thermal barrier | <radiobiology> In magnetic mirror devices, this is a depression of electrostatic potential formed by enhancing ion loss in the region between the central cell and the positive potential plug. The thermal barrier significantly reduces the density requirements in the plug and lowers the overall power required to sustain the solenoidal plugging by thermally decoupling central cell electrons from the end plugs. (09 Oct 1997) |
| camelids, new world | Ruminant mammals of south america. They are related to camels. (12 Dec 1998) |
| papua new guinea | A country consisting of the eastern half of the island of new guinea and adjacent islands, including new britain, new ireland, the admiralty islands, and new hanover in the bismarck archipelago; bougainville and buka in the northern solomon islands; the d'entrecasteaux and trobriand islands; woodlark (murua) island; and the louisiade archipelago. It became independent on september 16, 1975. Formerly, the southern part was the Australian territory of papua, and the northern part was the un trust territory of new guinea, administered by Australia. They were administratively merged in 1949 and named papua and new guinea, and renamed papua new guinea in 1971. (12 Dec 1998) |
