| 설명 | 허파 성숙도의 미숙으로 허파꽈리를 팽창시키는 물질(표면활성제)이 부족하여 호흡곤란이 초래되는 병으로서 미숙아에 호발하는데, 출생시 임신기간보다도 허파 성숙 정도가 더 관여된다. 단일 병으로서는 사망률이 가장 높으며(약 30%), 신생아의 대표적인 병이다. 임상적으로는 미숙아, 생후 6~8시간내 호흡곤란증세 출현과 생후 24~48시간의 증상 악화, 생후 2~3일간 인공적으로 산소를 공급하지 않으면 호흡을 계속시킬 수가 없으며 점점더 산소의 공급 의존도가 높아지며, 동맥혈액속의 산소농도가 내려가고 이산화탄소의 농도가 높으며, 흉부 방사선 소견을 참작하여 진단한다. 환아는 숙련된 간호 인력과 첨단 의료 장비가 설치된 신생아 집중 치료실에서 치료하여야 한다. 예후는 증세의 경중에 따라 다르고 사망률은 30~50% 된다. 어떤 아기에 있어서는 치료 후에 눈이나 기관지허파 계통에 장애를 일으키는 산소중독증이 보고되고 있다. |

| 설명 | 원형질 표면을 덮는 엷은막. 두께는 5~25μm이다. 광학현미경으로는 관찰할 수 없지만 전자현미경으로 관찰이 가능하다. 원형질막의 분자구조는 레시틴이나 콜레스테롤 등의 표면 활성물질 분자가 2분자층으로 그 표면에 배열되며, 이것을 각 1분자층의 단백질 분자가 양쪽에서 샌드위치한 단위막 구조이다. 전자현미경적으로 이 단위는 암-명-암의 3층(각 약 20nm)으로 구별된다. 원형질의 투과성에 중요한 구실을 하며, 생리상태가 변하면 그 투과성도 신속히 변한다. 또, 손상이 되면 쉽게 새로 형성된다. |

| basal membrane of saemicircular duct | The basal membrane underlying the epithelium of the saemicircular duct. Synonym: membrana basalis ductus saemicircularis, basal lamina of saemicircular duct. (05 Mar 2000) |
| basement membrane | <cell biology> Extracellular matrix characteristically found under epithelial cells. There are two distinct layers: the basal lamina, immediately adjacent to the cells, is a product of the epithelial cells themselves and contains collagen type IV and the reticular lamina is produced by fibroblasts of the underlying connective tissue and contains fibrillar collagen. (15 Nov 1997) |
| basilar membrane | A thin layer of tissue covered with mesothelial cells that separates the cochlea from the scala tympani in the ear. (18 Nov 1997) |
| basolateral plasma membrane | <cell biology> The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes). (18 Nov 1997) |
| Bichat's membrane | The inner elastic membrane of arteries. (05 Mar 2000) |
| black membrane | <chemistry> An artificial phospholipid membrane formed by painting a solution of phospholipid in organic solvent over a hole in a hydrophobic support immersed in water. Drainage of the solvent from the film produces diffraction colours until the thickness falls below the wavelength of light it then appears to be black. The structure is an extended bimolecular leaflet. (18 Nov 1997) |
| Bogros' serous membrane | A membrane of the episcleral space (of Tenon). (05 Mar 2000) |
| Bowman's membrane | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| branch of auriculotemporal nerve to tympanic membrane | Sensory branch of the auriculotemporal nerve supplying the external surface of the tympanic membrane. Synonym: ramus membranae tympani nervi auriculotemporalis, nerve of tympanic membrane. (05 Mar 2000) |
| bruch membrane | The membrane, also called the lamina basalis choroideae, that acts as a support structure on the inner side of the choroid (the vascular sheet that supplies the retinal pigment epithelium and the outer portion of the sensory retina adjacent to it). It is 7 microns thick and is composed of the basement membranes of the choriocapillaris endothelium and the retinal pigment epithelium. The membrane stops at the optic nerve, as does the retinal pigment epithelium. (12 Dec 1998) |
| Bruch's membrane | The transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym: basal lamina of choroid, basal layer of choroid, Bruch's membrane, Henle's membrane, lamina vitrea, vitreous lamella, vitreous membrane. (05 Mar 2000) |
| Brunn's membrane | The epithelium of the olfactory region of the nose. (05 Mar 2000) |
| bucconasal membrane | A thin, transient epithelial sheet separating the primitive nasal cavity from the stomodeum in the seven-week-old human embryo. Synonym: oronasal membrane. (05 Mar 2000) |
| buccopharyngeal membrane | A bilaminar (ectoderm and endoderm) membrane derived from the prochordal plate; after the embryonic head fold has evolved it lies at the caudal limit of the stomodeum. Synonym: oral membrane, oropharyngeal membrane. (05 Mar 2000) |
