| 영문 | nerve cell | 한글 | 신경세포 |
|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

| 영문 | glia cell | 한글 | 아교세포 |
|---|---|---|---|
| 설명 | 신경세포 사이에서 그물구조를 이루며 이를 지지하는 조직. 신경아교세포는 신경모세포와 갈라진 아교모세포가 다시 여러 형태로 분화-성장한 것이다. 뇌실이나 척수중심관의 벽을 덮고 원주상 또는 입방형이며, 초기에는 유리면에 섬모가 있다. 대형세포는 별뇌실막세포는 아교세포라고 하며, 신경세포나 신경섬유 사이에 산재한다. 그 외에 희소돌기아교세포도 포함된다. |

| 영문 | reserve cell | 한글 | 예비세포 |
|---|---|---|---|
| 설명 | 일반적으로 상피조직에서 이미 있던 상피세포가 손상을 받아 사멸하면 매꿔지는 그 밑에 있는 미분화세포 예를 들면, 기관지 내표면을 덮는 중층 원주 상피의 기저에 있는 작은 미분화 상피 세포. |

| 영문 | stem cell | 한글 | 줄기세포, 간세포 |
|---|---|---|---|
| 설명 | 자기 복제를 하여 자신을 존속시키면서 한편으로는 증식과 분화를 하여 새로운 세포를 형성하는 세포로서 조혈줄기세포가 대표적이다. 조혈줄기세포는 골수에 있는 세포로서 모든 혈구세포가 여기에서 분화되어 발생한다. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

| Friend spleen focus forming virus | <virology> Defective virus found in certain strains of Friend virus, detected by its ability to form foci in spleens of mice and believed to be responsible in those strains for the production of a leukaemia associated with polycythaemia rather than anaemia. (18 Nov 1997) |

| atheromatous plaque | A well-demarcated yellow area or swelling on the intimal surface of an artery; produced by intimal lipid deposit. (05 Mar 2000) |
| atherosclerotic plaque | <cardiology, pathology> A buildup of cholesterol and fatty material within a blood vessel due to the effects of atherosclerosis. (27 Sep 1997) |
| bacterial plaque | In dentistry, a mass of filamentous microorganisms and large variety of smaller forms attached to the surface of a tooth which, depending on bacterial activity and environmental factors, may give rise to caries, calculus, or inflammatory changes in adjacent tissue. Synonym: dental plaque, mucous plaque, mucinous plaque. (05 Mar 2000) |
| bacteriophage plaque | A clear circular zone in an otherwise confluent growth of bacteria on an agar surface resulting from bacterial lysis by bacterial viruses. (05 Mar 2000) |
| plaque | <dentistry> Dental plaque is a combination of food (left in the mouth after eating), bacteria (which live in the mouth) and bacterial byproducts (acidic wastes). These acidic wastes can break down the tooth enamel leading to tooth decay. Plaque also irritates the gum tissue (see gingivitis) and eventually destroys periodontal tissue, promoting periodontal disease. (27 Sep 1997) |

| plaque assay | 1. <investigation> Assay for virus in which a dilute solution of the virus is applied to a culture dish containing a layer of the host cells, convective spread is prevented by making the medium very viscous. After incubation the plaques, areas in which cells have been killed (or transformed), can be recognised and the number of infective virus particles in the original suspension estimated. 2. Assay for cells producing antibody against erythrocytes or against antigen that has been bound to the erythrocytes. The cell is surrounded by a clear plaque of haemolysis. Basic principle behind the assay is the same as for the virus plaque assay. (18 Nov 1997) |
| Plaque Index | An index for estimating the status of oral hygiene by measuring dental plaque which occurs in the areas adjacent to the gingival margin. (05 Mar 2000) |
| mucous plaque | In dentistry, a mass of filamentous microorganisms and large variety of smaller forms attached to the surface of a tooth which, depending on bacterial activity and environmental factors, may give rise to caries, calculus, or inflammatory changes in adjacent tissue. Synonym: dental plaque, mucous plaque, mucinous plaque. (05 Mar 2000) |
| pleural plaque | Fibrous thickening of the parietal pleura, characteristically caused by inhalation exposure to asbestos. (05 Mar 2000) |
| haemolytic plaque assay | <investigation> A haemolytic plaque assay is a lab technique used to show that certain antibodies are secreted by antibody-making cells when these cells are mixed with red blood cells. The mixture is spread onto a plate of agar, if a plaque appears, it means that the red blood cells have been destroyed (by haemolysis) by the antibodies. (09 Oct 1997) |
| senile plaque | <neurology> Characteristic feature of the brains of Alzheimer's patients and aged monkeys, consisting of a core of amyloid fibrils surrounded by dystrophic neurites. The principal component of amyloid fibrils in senile plaques is B/A4, a peptide of about 4 kD that is derived from the larger amyloid precursor protein (APP). The B/A4 sequence is located near the C terminus of APP. (18 Nov 1997) |
