| 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. |

| postinfarction ventricular septal defect | A defect developed in the ventricular septum resulting from rupture of an acute myocardial infarction. (05 Mar 2000) |
| salt-losing defect | Renal tubular abnormality causing loss of sodium in the urine. (05 Mar 2000) |
| septal defect, atrial | A hole in the septum, the wall, between the atria, the upper chambers of the heart. Commonly called an asd. Asds are a major class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| septal defect, ventricular | A hole in the interventricular septum, the wall between the ventricles, the lower chambers of the heart. Commonly called a vsd. Vsds are a common class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| neural tube defect | <neurology, paediatrics> Abnormal development during embryonic life of the neural tube producing congenital malformations of the nervous system due to closure failure of the neural tube. The structure gives rise to the central nervous system (the brain and spinal cord), and failure to close results in anencephaly (absence of the cranial vault and absence of most or all of the cerebral hemispheres of the brain) and spina bifida or meningomyelocele (open spina with exposure and protusion of the spinal cord). The risk of neuroal tube defects can be decreased by the mother taking folic acid during pregnancy. (04 Jul 1999) |
| defect | 1. Want or absence of something necessary for completeness or perfection; deficiency; opposed to superfluity. "Errors have been corrected, and defects supplied." (Davies) 2. Failing; fault; imperfection, whether physical or moral; blemish; as, a defect in the ear or eye; a defect in timber or iron; a defect of memory or judgment. "Trust not yourself; but, your defects to know, Make use of every friend any every foe." (Pope) "Among boys little tenderness is shown to personal defects." (Macaulay) Synonym: Deficiency, imperfection, blemish. See Fault. Origin: L. Defectus, fr. Deficere, defectum, to desert, fail, be wanting; de- + facere = to make, do. See Fact, Feat, and cf. Deficit. Source: Websters Dictionary (01 Mar 1998) |
| defect, atrial septal | A hole in the septum, the wall, between the atria, the upper chambers of the heart. Commonly called an ASD. ASDs are a major class of congenital cardiac malformation. (12 Dec 1998) |
| defect, enzyme | An abnormality in the protein (enzyme) important in catalyzing a normal biochemical reaction in the body. Disorders result from a deficiency (or functional abnormality) of an enzyme. Archibald Garrod in 1902 was the first to attribute a disease to an enzyme defect: an inborn error of metabolism. Today, newborns are routinely screened for certain enzyme defects such as phenylketonuria (PKU) and galactosaemia, an error in the handling (metabolism) of the sugar galactose. (12 Dec 1998) |
| defect, ventricular septal | Hole in the interventricular septum, the wall between the ventricles (lower chambers of the heart). Commonly called a VSD. VSDs are a common class of heart deformity present at birth (congenital cardiac malformation). (17 Dec 1998) |
| iodide transport defect | See: familial goiter. (05 Mar 2000) |

| oesophageal filling defect | <radiology> Tumour, carcinoma (oesophagus, stomach extending proximally), leiomyoma / leiomyosarcoma, polyp: fibrovascular, inflammatory, adenomatous, papilloma, carcinosarcoma, lymphoma, metastasis, oesophageal varix, extrinsic lesion (vascular impression, adenopathy, cyst), foreign body (12 Dec 1998) |
| osteoporotic marrow defect | Focal osteoporotic bone marrow defect of the jaw; a focal radiolucent defect composed of normal marrow. (05 Mar 2000) |
| Eisenmenger's defect | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
