| 영문 | bone age | 한글 | 뼈나이, 골연령 |
|---|---|---|---|
| 설명 | 생리적 연령의 일종으로 나이를 더함에 따른 뼈의 성숙도를 평가하여 어린이의 전신발육을 판정하는 것이다. 뼈나이 평가에는 손목뼈나 발목뼈의 X선사진을 바탕으로 각 화골중심의 형태나 수를 평가한다. 손목뼈의 화골개수를 세는 방법은 간단해서 그의 수는 난 해를 포함한 연령과 거의 일치하지만 뼈발육의 지속을 가늠할 수 있다. |

| 영문 | bone scan | 한글 | 뼈스캔 |
|---|---|---|---|
| 설명 | 뼈의 무기질은 칼슘과 인산염으로 이루어져 있다. 그래서 뼈에 병터가 있는 경우에는 뼈의 인산염분포나 양이 변화하게 된다. 이것을 이용하여 인산염에다가 방사선을 내보내는 물질을 붙여 환자에게 투여하고 그 물질이 내보내는 방사선을 이용하여 영상을 만들어서 뼈의 전반적인 상태나 병터의 발견에 이용하는 방법을 뼈스캔(bone scan)이라고 한다. |

| 영문 | mandibular bone, mandible | 한글 | 아래턱뼈, 하악골 |
|---|---|---|---|
| 설명 | 얼굴을 구성하는 뼈의 한 종류로써, 흔히 말하는 "턱"을 이루는 뼈를 말한다. 얼굴뼈를 이루는 뼈는 위턱뼈(maxillary bone), 아래뼈(mandibular bone), 눈물뼈(lacrimal bone), 코뼈(nasal bone), 광대뼈(zygomatic bone), 보습뼈(vomer) 등이 있다. |

| 영문 | red bone marrow | 한글 | 적색골수 |
|---|---|---|---|
| 설명 | 분화중의 갈비뼈, 척추뼈나 그 외의 많은 작은 뼈에 있는 활동성 골수이다. 적혈구나 과립백혈구의 생산 장소이다. |

| 영문 | nasal bone | 한글 | 코뼈 |
|---|---|---|---|
| 설명 | 코뿌리의 기초를 이루는 사다리꼴의 얇은 뼈로 좌우 한 쌍의 물렁뼈이며, 정중앙선에서 붙어 있다. 코뼈의 윗모서리는 이마뼈, 아래모서리는 코선반연골, 가쪽모서리는 위턱뼈이마돌기와 접한다. 바깥면은 평활하지만 속안면은 요면을 이루며, 세로로 걸친 벌집뼈신경구는 코뼈구멍으로 연결되어 앞벌집뼈신경과 통한다. |

| density dependent inhibition of growth | <cell culture> The phenomenon exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached. The critical density is considerably higher for most cells than the density at which a monolayer is formed, for this reason, most cell behaviourists prefer the term density dependent inhibition of growth as this avoids any confusion with contact inhibition of locomotion, a totally different phenomenon that is contact dependent. (12 Jan 1998) |

| density gradient | <chemistry> A column of liquid in which the density varies continually with position, usually as a consequence of variation of concentration of a solute. Such gradients may be established by progressive mixing of solutions of different density as for example: sucrose gradients) or by centrifuge induced redistribution of solute (as for caesium chloride gradients). Density gradients are widely used for centrifugal and gravity induced separations of cells, organelles and macromolecules. The separations may exploit density differences between particles or primarily differences in size, in which latter case the function of the gradient is chiefly to stabilise the liquid column against mixing. (12 Jan 1998) |
| density gradient centrifugation | <technique> High-speed centrifugation inwhich molecules float at a point wheretheir density equals that in a gradient of cesium chloride or sucrose. (12 Jan 1998) |
| incidence density | The person-time incidence rate. (05 Mar 2000) |
| intermediate density lipoprotein | Class of lipoproteins formed in degradation of very-low-density lipoproteins; about half are cleared quickly from the plasma into the liver by receptor-mediated endocytosis; the other half are degraded into low density lipoproteins. (05 Mar 2000) |
| inverse density dependence | <epidemiology> See density dependence. (05 Dec 1998) |
| optical density | 1. <chemistry, investigation> Absorbance is defined as a logarithmic function of the percent transmission of a wavelength of light through a liquid. 2. <microbiology> This can be used as a measure of the amount of light absorbed by a suspension of bacterial cells or a solution of an organic molecule, it is measured by a colourimeter or spectrophotometer. Absorbance values are used to plot the growth of bacteria in suspension cultures and to gauge the purity and concentration of molecules (such as proteins) in solution. See: absorption. (15 Jan 1998) |
| organismal density | <microbiology> Number of organisms or items per unit area or volume. (09 Oct 1997) |
| either particle flux density | The particle fluence rate, or energy flux density, the energy fluence rate of intensity. Compare: fluence. (05 Mar 2000) |
| familial high density lipoprotein deficiency | Familial high {density lipoprotein deficiency}; a heritable disorder of lipid metabolism characterised by almost complete absence from plasma of high density lipoproteins, and by storage of cholesterol esters in foam cells, tonsillar enlargement, an orange or yellow-gray colour of the pharyngeal and rectal mucosa, hepatosplenomegaly, lymph node enlargement, corneal opacity, and peripheral neuropathy; autosomal recessive inheritance. Synonym: familial high {density lipoprotein deficiency}, Tangier disease. Origin: G. An-, priv., + alpha, a, + lipoprotein + -aemia, blood (05 Mar 2000) |
| flux density | <radiobiology> Total amount of a quantity passing through a unit surface area in unit time See: flux. (09 Oct 1997) |
| low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats in the bloodstream. High levels of low density lipoprotein are considered a positive risk factor for the development of coronary artery disease. Less than 130 mg/dl is desirable, 130 to 159 mg/dl is borderline high, over 160 is considered high. Acronym: LDL (10 Jan 1998) |
| low density lipoprotein receptor | <biochemistry> A cell surface protein that mediates the endocytosis of low density lipoprotein by cells. Genetic defects in low density lipoprotein receptors lead to abnormal serum levels of low density lipoprotein and hypercholesterolaemia. (16 Mar 1998) |
| low-density lipoprotein receptors | Receptors on the surface of cells, especially liver cells, which bind to low density lipoprotein and promote clearance of LDL from the plasma. (05 Mar 2000) |
| bone within a bone | <radiology> STOP heavy metal, S: sickle cell disease, T: Thorotrast, O: osteopetrosis, P: Paget's disease, heavy metals, hypervitaminosis D (12 Dec 1998) |
