| 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. |

| uraemic colitis | Colitis characterised by haemorrhages in the mucosa, occurring in renal failure, possibly owing to the irritant effect of ammonia formed by breakdown of increased urea in the intestinal secretions. (05 Mar 2000) |
| adamantine membrane | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth.
