| 설명 | 치아의 한 부분을 이르는 말이다. 치아관을 피복하는 회백색 반투명의 단단한 물질이다. 치아는 크게 치아관(crown)과 치근(root)으로 나눌 수가 있다. 치아관이란 구강내로 돌출하고 있는 치아의 부분이며, 치근이란 치아관 아래에 존재하는 치아의 부분을 말한다. 사기질은 치아관을 둘러싸고 있는 아주 단단한 조직으로 우리가 입안으로 직접 관찰할 수가 있는 흰색을 띠는 것이다. 전신에서 가장 단단한 부분으로 굳기 6~7° 이므로 석영과 거의 비슷하다. 사기질소주라고 하는 3~5μm 굵기의 사상체의 집합으로 한 개의 이에 수백만 개의 작은기둥이 있다. 사기질은 한번 마모되거나 녹아 버리면 다시 신생되지 않는다. 잇몸의 내부에 있는 치근부에서는 상아질 표면이 시멘트질로 덮여 있다. 사기질에는 신경이 없으므로 여기에 생긴 충치에는 치통이 없으나, 상아질까지 침범되었을 때 냉수가 스며들면 이가 시리고 치통이 시작된다. 소량의 플루오르화물을 섭취하면 이가 건강해진다고 하지만 과다하면 사기질을 상하게 한다. |

| Auer rods | Rod-shaped structures of uncertain nature in the cytoplasm of immature myeloid cells, especially myeloblasts, in acute myelocytic leukaemia; may be an abnormal form of lysosomes; they contain peroxidase and acid phosphatase, and stain red by azure-eosin stains. Synonym: Auer rods. (05 Mar 2000) |

| gram-negative aerobic rods and cocci | <microbiology> A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes. (12 Dec 1998) |
| gram-negative anaerobic straight, curved, and helical rods | <microbiology> A group of anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative facultatively anaerobic rods | <microbiology> A large group of facultatively anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-positive asporogenous rods | <microbiology> A gram-positive, non-spore-forming group of bacteria comprising organisms that have morphological and physiological characteristics in common. (12 Dec 1998) |
| gram-positive asporogenous rods, irregular | <microbiology> A group of irregular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive asporogenous rods, regular | <microbiology> A group of regular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive endospore-forming rods | <microbiology> Rod-shaped bacteria that form endospores and are gram-positive. Representative genera include bacillus and clostridium. (12 Dec 1998) |
| gram-positive rods | <microbiology> A large group of rod-shaped bacteria that retains the crystal violet stain when treated by gram's method. (12 Dec 1998) |
| rods (retina) | One of the two photoreceptor cell types of the vertebrate retina. In rods the photopigment is in stacks of membranous disks separate from the outer cell membrane. Rods are more sensitive to light than cones, but rod mediated vision has less spatial and temporal resolution than cone vision. (12 Dec 1998) |
| Corti's rods | Cell's forming the outer and inner walls of the tunnel in the organ of Corti. Synonym: Corti's pillars, Corti's rods, pillar cells of Corti, tunnel cells. (05 Mar 2000) |
| napier's rods | A set of rods, made of bone or other material, each divided into nine spaces, and containing the numbers of a column of the multiplication table; a contrivance of Baron Napier, the inventor of logarithms, for facilitating the operations of multiplication and division. Source: Websters Dictionary (01 Mar 1998) |
| layer of rods and cones | The layer of the retina next to the pigment layer and containing the visual receptors. See: retina, granular layers of retina, neuroepithelial layer of retina. Synonym: bacillary layer. (05 Mar 2000) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| mottled enamel | Alterations in enamel structure due to excessive fluoride ingestion during tooth formation; varies in appearance from small white opacities to yellow and black spotting. Nanoid enamel, a condition of abnormal thinness of the enamel. Synonym: dwarfed enamel. Whorled enamel, enamel in which the rods assume a spiral or twisting course. (05 Mar 2000) |
