| 설명 | 피부나 점막이 푸르스름해지는 것으로 환원 적혈구가 많을 경우에 나타난다. 적혈구속에 산소와 결합하여 산소를 운반하는 역할을 하는 것을 혈색소라고 하는데 이 혈색소가 산소와 결합하지 못한 것을 환원 혈색소라고 한다. 대개 이 환원적혈구의 혈중농도가 5%이상일 경우에 청색증이 나타난다. 이 청색증은 특히, 입술, 손가락의 끝, 귀 등에서 쉽게 관찰이 되어진다. 이 청색증은 중심성과 말초성의 두 가지로 나뉘어질 수가 있다. 중심성 청색증(central cyanosis)은 혀, 입술, 구강점막 등 중심부위에 주로 청색증이 나타나는 경우로 이 경우는 폐에서 가스교환의 문제가 있어서 동맥혈에 일정량 이하의 산소가 포함이 되어 있는 경우에 생기는 현상으로 호흡기 질환이나, 해발 2400미터이상의 고지에 있는 경우에 생길 수가 있다. 말초성 청색증(peripheral cyanosis)은 손가락 등의 신체의 말단 부위에 청색증이 있는 경우로 주로 혈류의 순환의 이상으로 혈류가 신체의 말초에 지체되어 있는 경우에 주로 발생한다. |

| cyanosis | <clinical sign> A bluish discolouration, applied especially to such discolouration of skin and mucous membranes due to excessive concentration of reduced haemoglobin in the blood. Origin: Gr. Kyanos = blue (21 May 1997) |
|---|---|
| cyanosis retinae | Venous congestion of the retina. Shunt cyanosis, any blue colour of the entire skin or a region of the skin or mucous membrane due to a right to left shunt permitting unoxygenated blood to reach the left side of the circulation. (05 Mar 2000) |
| hereditary methemoglobinaemic cyanosis | Methemoglobinaemia due to formation of any one of a group of abnormal a chain or b chain haemoglobins collectively known as haemoglobin M. Slate-gray cyanosis occurs in early infancy, without pulmonary or cardiac disease, and is resistant to ascorbic acid or methylene blue therapy; autosomal dominant inheritance, methemoglobinaemia due to deficiency of cytochrome b5 reductaseor methemoglobin reductase, the enzyme responsible for reduction of intraerythrocyte methemoglobin; cyanosis is improved by ascorbic acid or methylene blue; autosomal recessive inheritance, one case of methemoglobinaemia has been reported that apparently is due to a deficiency of cytochrome b5. Synonym: hereditary methemoglobinaemia, hereditary methemoglobinaemic cyanosis, primary methemoglobinaemia. (05 Mar 2000) |
| tardive cyanosis | cyanose tardive |
| toxic cyanosis | Cyanosis due to methemoglobin formation resulting from the action of certain drugs, e.g., nitrites. (05 Mar 2000) |
| late cyanosis | cyanose tardive |
| automated differential leukocyte counter | An instrument using digital imaging or cytochemical techniques to differentiate leukocytes. (05 Mar 2000) |
| Begg light wire differential force technique | An orthodontic appliance utilizing small gauge labial wires with expansion and contraction loops formed into it and attached to bands fitted to individual teeth; sometimes called Begg light wire differential force technique. (05 Mar 2000) |
| calorimetry, differential scanning | Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample. (12 Dec 1998) |
| white blood cell differential | <haematology> The white blood cell differential is a percentage of each type of white blood cell based on a count of 100 white cells. A change in the white blood cell type (to neutrophils or bands) can indicate a bacterial infection. Neutrophils, bands, lymphocytes, monocytes, basophils and eosinophils are all included. (13 Nov 1997) |
| semantic differential | Analysis of word concepts by the association of polar adjectives, e.g., good-bad, with the concept, father. The adjectives are usually scaled in 7 steps. The subject's placement of the concept on the adjectival scale indicates the connotative meaning of the concept. (12 Dec 1998) |
| diagnosis, differential | 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 | 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. (18 Nov 1997) |
| differential blood pressure | The arterial blood pressure at corresponding points on the two sides of the body. (05 Mar 2000) |
