| 설명 | 단위시간에 어떤 물질이 분비기관을 통하여 혈액에서 제거되는 현상 혹은 제거할 수 있는 능력. 치과용어로는 지대치 형성된 치아의 교합면과 대합치 교합면과의 거리 또는 대합치 교합면간의 거리를 주로 나타내고, 기타 서로 마주보고 있는 물체간의 거리를 나타낼 경우에도 적용된다. |

| 설명 | 청소(clearance)란 피속에서 어떤 물질을 제거하는 속도를 의미한다. 피속에서 어떤 물질을 제거하는 것은 주로 콩팥의 역할이므로 콩팥에서의 어떤 물질이 제거되는 청소율이 임상적으로 중요하다. 콩팥에서의 어떤 물질의 청소율은 다음과 같은 식으로 구해진다. C(creatinine clearance) = V × U / P C란 콩팥의 청소율의 약자이고 V는 1분당 나오는 소변의 양으로 ml/min이란 단위로 표시한다. 그리고 U란 소변에 들어 있는 청소율 측정의 대상이 되는 물질의 농도이다. P란 청소율 측정의 대상이 되는 물질의 혈액 중의 농도를 나타낸다. 크레아티닌 청소란 크레아틴이라는 물질의 청소율을 나타내는 말로 콩팥 기능의 평가에 많이 사용되는 지표이다. |

| free water clearance | The amount of water excreted in the urine beyond that which would accompany the excreted solutes if the urine were isosmotic with plasma; it represents the loss of body water in excess of solute tending to raise body osmolality and making urine hyposmotic. Unlike other clearance's, it is calculated by subtracting the osmolal clearance from the actual volume of urine excreted per minute. A negative value for free water clearance represents the amount of water that the body has reclaimed from isosmotic tubule fluid to make the urine hyperosmotic and to lower body osmolality.

| carbon dioxide-free water | Purified water that has been boiled vigorously for 5 minutes or more. (05 Mar 2000) |

| free water | Water in the body that can be removed by ultrafiltration and in which substances can be dissolved. (05 Mar 2000) |
| amylase-creatinine clearance ratio | A test for the diagnosis of acute pancreatitis; it is determined by measuring amylase and creatinine in serum and urine in apparently healthy individuals the renal clearance of amylase is less than 5% that of creatinine; in acute pancreatitis the ratio is said to be greater than 0.05 or 5%. (05 Mar 2000) |
| ANP clearance receptors | Cell surface proteins that bind atrial natriuretic peptide and ANP fragments without initiating biological action. (05 Mar 2000) |
| p-aminohippurate clearance | A good measure of renal plasma flow, which it slightly underestimates; when a low plasma concentration of p-aminohippurate (PAH) is maintained by intravenous infusion, the kidney extracts and excretes almost all of the PAH from the plasma before it reaches the renal vein. (05 Mar 2000) |
| maximum urea clearance | The urea clearance when the urine flow exceeds 2 ml/min; normal value is about 75 ml blood/min per 1.73 m2 body surface area. (05 Mar 2000) |
| metabolic clearance rate | Volume of biological fluid completely cleared of drug metabolites as measured in unit time. Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site. (12 Dec 1998) |
| clearance | 1. The process of clearing. 2. <physiology> The rate at which a substance is removed from the blood. (18 Nov 1997) |
| mucociliary clearance | Rate of ciliary and secretory activity of the respiratory submucosal glands. It is a non-specific host defense mechanism, measurable in vivo by mucus transfer, ciliary beat frequency, and clearance of radioactive tracers. (12 Dec 1998) |
| creatinine clearance | Measurement of the clearance of endogenous creatinine, used for evaluating the glomerular filtration rate (GFR). (05 Mar 2000) |
| creatinine clearance test | <investigation, nephrology> A test of the amount of creatinine in blood or in blood and urine shows if the kidneys are working right or if one or both are diseased. (09 Oct 1997) |
| standard urea clearance | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula. (05 Mar 2000) |
| steroid metabolic clearance rate | A measure of the rate of metabolism of a given steroid within the body, usually expressed as liters of body fluid that contain the amount of steroid metabolised per day. (05 Mar 2000) |
| interocclusal clearance | The space between the occluding surfaces of the maxillary and mandibular teeth when the mandible is in physiologic resting position. Synonym: interocclusal clearance, interocclusal distance, interocclusal gap, interocclusal rest space. (05 Mar 2000) |
| inulin clearance | An accurate measure of the rate of filtration through the renal glomeruli, because inulin filters freely with water and is neither excreted nor reabsorbed through tubule walls. Inulin is not a normal constituent of plasma and must be infused continously to maintain a steady plasma concentration and a steady rate of urinary excretion during the measurement. Inulin clearance in a normal adult person is about 120 ml/min (range 100-150) per 1.73 m2 body surface area. (05 Mar 2000) |
| free water clearance |
Free water clearance is used to express quantitatively the renal tubular handling of water. It represents the difference between the actual volume of urine produced per unit time and the volume required to excrete that amount of solute iso-osmotically with plasma. It can be calculated using the equation:
