| 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. |

| 영문 | cerebrospinal fluid(CSF) | 한글 | 뇌척수액 |
|---|---|---|---|
| 설명 | 거미막밑공간과 뇌실을 채우고 있으면서 뇌와 척수를 쌓고 있는 맑은 액체를 뇌척수액이라 한다. 거미막밑공간이란 3개의 층(밖에서 부터 경질막, 거미막, 유막)으로 이루어진 뇌막 중에서 2번째 층에 해당하는 거미막의 아래의 공간으로 가장 밑에 있는 뇌막인 유막의 위에 존재하는 공간이다. 뇌실이란 뇌속에 존재하는 공간으로 그 속에는 뇌실액으로 채워져 있다. 뇌와 척수는 고체이고 이것들을 둘러쌓는 뇌척수액은 액체이므로 뇌, 척수는 뇌척수액속에 떠있는 결과가 된다. 이는 외부의 충격으로부터 뇌와 척수를 보호하는데 유용하다.  |

| 영문 | extracellular fluid | 한글 | 세포외액 |
|---|---|---|---|
| 설명 | 세포외에 존재하는 모든 체액에 대한 일반명. 사이질액, 혈장, 림프액, 뇌척수액 등을 포함한다. 즉, 능동적인 세포분비에 의해 생기는 액으로 이루어진다. 일정한 세포의 정상적 외환경을 만들어 준다. |

| 영문 | amniotic fluid | 한글 | 양수 |
|---|---|---|---|
| 설명 | 임신시에 태아는 얇은 막에 둘러쌓여 있고 이 막과 태아사이에 액체가 있다. 이 막을 양막(amnion)이라고 하고 양막속의 액체 양수라고 한다. |

| 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-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) |
| 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-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) |
| allantoic fluid | The fluid within the allantoic cavity. (05 Mar 2000) |
| amniotic fluid | <anatomy, obstetrics> The fluid that surrounds the developing foetus within the amniotic sac. This environment cushions the baby from injury and plays an important role in foetal development. (05 Feb 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| amniotic fluid syndrome | <syndrome> Pulmonary embolic phenomena thought to be due to infusion of amniotic fluid containing epithelial squames into maternal blood vessels; shock ensues and sudden death may occur. (05 Mar 2000) |
