| 영문 | fasting blood sugar | 한글 | 공복혈당, 빈속혈당 |
|---|---|---|---|
| 설명 | 혈액속에 포함되어 있는 포도당. 뇌와 적혈구의 에너지원이 되고, 그 양은 운동, 식사 따위에 의하여 달라진다. 건강인의 아침 공복시 혈중 포도당 농도는 60~100mg/dL이지만 기타의 당질 즉 과당, 갈락토스, 5탄당은 미량이며 일반적으로 혈당일 하면 혈중포도당을 의미한다. 혈당은 생체의 에너지원으로서 가장 중요한 물질이다. 그 농도는 창자관으로부터의 흡수, 간에 있어서의 당신생과 글리코겐의 합성-분해, 말초조직의 당이용, 콩팥으로부터의 배설 등 여러 인자에의해 좌우되며 그 조절에는 자율신경과 각종 호르몬이 밀접하게 관계한다. 특히 혈당저하작용에는 인슐린이, 그리고 혈당상승작용에는 에피네프린, 글루카곤, 성장호르몬, 부신겉질호르몬, 부신겉질자극호르몬, 갑상샘 호르몬이 관계가 있으며 그것들의 대항 및 협조 작용에 의해 혈당치가 조절된다. |

| differential | 1. Relating to or indicating a difference; creating a difference; discriminating; special; as, differential characteristics; differential duties; a differential rate. "For whom he produced differential favors." (Motley) 2. <mathematics> Of or pertaining to a differential, or to differentials. 3. <mechanics> Relating to differences of motion or leverage; producing effects by such differences; said of mechanism. Differential calculus. <mathematics> A portable hoisting apparatus, the same in principle as the differential windlass. A hoisting pulley to which power is applied through a differential gearing. Differential screw, a compound screw by which a motion is produced equal to the difference of the motions of the component screws. Differential thermometer, a thermometer usually with a U-shaped tube terminating in two air bulbs, and containing a coloured liquid, used for indicating the difference between the temperatures to which the two bulbs are exposed, by the change of position of the coloured fluid, in consequence of the different expansions of the air in the bulbs. A graduated scale is attached to one leg of the tube. Differential windlass, or Chinese windlass, a windlass whose barrel has two parts of different diameters. The hoisting rope winds upon one part as it unwinds from the other, and a pulley sustaining the weight to be lifted hangs in the bight of the rope. It is an ancient example of a differential motion. Origin: Cf. F. Differentiel. 1. <mathematics> An increment, usually an indefinitely small one, which is given to a variable quantity. According to the more modern writers upon the differential and integral calculus, if two or more quantities are dependent on each other, and subject to increments of value, their differentials need not be small, but are any quantities whose ratios to each other are the limits to which the ratios of the increments approximate, as these increments are reduced nearer and nearer to zero. 2. A small difference in rates which competing railroad lines, in establishing a common tariff, allow one of their number to make, in order to get a fair share of the business. The lower rate is called a differential rate. Differentials are also sometimes granted to cities. 3. <physics> One of two coils of conducting wire so related to one another or to a magnet or armature common to both, that one coil produces polar action contrary to that of the other. A form of conductor used for dividing and distributing the current to a series of electric lamps so as to maintain equal action in all. <mathematics> Partial differential, the differential of a function of two or more variables, when each of the variables receives an increment. The total differential of the function is the sum of all the partial differentials. Source: Websters Dictionary (01 Mar 1998) |

| differential adhesion | The differential adhesion hypothesis was advanced by Steinberg to explain the mechanism by which heterotypic cells in mixed aggregates sort out into isotypic territories. Quantitative differences in homo and hetero typic adhesion are supposed to be sufficient to account for the phenomenon without the need to postulate cell type specific adhesion systems: fairly generally accepted, although some tissue specific cell adhesion molecules are now known to exist.

| differential centrifugation | A technique for separating organellesor other differently-sized cellcomponents in a centrifuge, particles of the same size and weight willsettle out into common layers. (09 Oct 1997) |
| differential diagnosis | The determination of which two or more diseases with similar symptoms is the one from which a patient is suffering from based on an analysis of the clinical data. (27 Sep 1997) |
| differential display PCR | Method of image formation in the light microscope based on the method proposed by Nomarski (though strictly speaking all forms of optical microscopy rely to a greater or lesser extent on differential interference). The light beam is split by a Wollaston prism in the condenser, to form slightly divergent beams polarized at right angles. One passes through the specimen (and is retarded if the refractive index is greater) and one through the background nearby: the two are recombined in a second Wollaston prism in the objective and interfere to form an image. The image is spuriously three dimensional the nucleus, for example: appears to stand out above the cell (or be hollowed out) because it has a higher refractive index than the cytoplasm. The Nomarski system has the advantage that there is no phase halo, but the contrast is low and image formation with crowded cells is poor because the background does not differ from the specimen. (18 Nov 1997) |
| differential equation | <epidemiology> The mathematical formulation corresponding to a continuous model; an equation involving derivatives. (05 Dec 1998) |
| differential gene expression | Gene expression that responds to signals or triggers; a means of gene regulation; e.g., effects of certain hormones on protein biosynthesis. (05 Mar 2000) |
| differential growth | Different rates of growth in associated tissues or structures; used especially in embryology when the differences in growth rates result in changing the original proportions or relations. (05 Mar 2000) |
| differential interference contrast | <technique> A mode of contrast generation in microscopy that yields an image with a shadow relief. The relief reflects the gradient of optical path difference. Differential Interference Contrast, which is a form of interferenc microscopy that uses polarizing beam splitters, can be of the Smith or Nomarski type. Acronym: DIC (05 Aug 1998) |
| differential manometer | Any device that indicates the difference in pressure between two fluids, regardless of any changes in their absolute pressures. Mercurial manometer, an manometer in which the varying pressures are shown by differences of elevation in a column of mercury. (05 Mar 2000) |
| differential medium | A medium which is used to differentiate different types of microorganisms based on their different colours or colony shapes. Examples of differential media are: Macconkey's agar and SS agar. (09 Oct 1997) |
| differential renal function test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |
| differential screening | Process in development of a multicellular organism by which cells become specialised for particular functions. Requires that there is selective expression of portions of the genome, the fully differentiated state may be preceded by a stage in which the cell is already programmed for differentiation but is not yet expressing the characteristic phenotype determination. (18 Nov 1997) |
| differential spinal anaesthesia | A form of diagnostic spinal anaesthesia producing blockade of different types of nerves in the subarachnoid space, based upon their differences in sensitivity to local anaesthetics; also observed during surgical spinal anaesthesia. (05 Mar 2000) |
