|---|---|---|---|
| 설명 | 삼투라는 현상은 일정 크기 이하의 물질은 통과시키고 그 이상의 크기를 가진 물질은 통과 시키지 못하게 하는 막(반투막)을 사이에 두고 양쪽에 그 막을 투과하지 못하는 물질의 농도가 차이가 날 때 발생하는 것으로 막을 통과할 수 있는 물질이 막 양쪽의 통과 할 수 없는 물질의 농도를 같게 하는 방향으로 움직이는 것을 말한다. |

|---|---|---|---|
| 설명 | 적혈구세포의 삼투압 특성 변화에 대한 민감성. 적혈구가 저농도의 나트륨 용액에 노출하면 세포막의 능력을 초과할 때까지 다량의 물을 흡수하여 부풀어올라 파열하고 고농도의 나트륨 용액에 노출하면 적혈구의 세포내액이 빠져나가 크기가 줄어들며 파괴된다. 예외적 취약성이나 저항성은 특정 병의 진단적 기준이 될수 있다. 정상세포는 0.39~0.45% 소금물 용액에서 용혈이 시작되며, 37℃(98.6℉)에서 0.30~0.33% 소금 용액에 적혈구를 노출시키면 용혈은 24시간 이내에 완료된다. |

| osmotic nephrosis | Swelling of renal tubular epithelium associated with glomerular filtration of sugars and dextrose; the swelling is due to formation of cytoplasmic vesicles by pinocytosis, and is reversible, probably with no dysfunction, when produced by glucose or mannitol. (05 Mar 2000) |

| diuretics, osmotic | Diuretics that are filtered at the glomerulus and reabsorbed in the renal tubule only to a limited extent. They thus increase the amount of osmotically active solute in the urine and a corresponding increase in urine volume. These compounds also increase the osmolality of plasma, thereby increasing the diffusion of water from the intraocular and cerebrospinal fluids; they can be used for reducing the pressure and volume of these fluids. (12 Dec 1998) |
|---|---|
| iso-osmotic | <physiology> Having the same total osmotic pressure or osmolality as another fluid (ordinarily intracellular fluid); such a fluid is not isosmotic if it includes solutes that freely permeate cell membranes. Synonym: iso-osmotic. (05 Mar 2000) |
| osmotic | <chemistry> Pertaining to or of the nature of osmosis (= the passage of pure solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a membrane which selectively prevents the passage of solute molecules, but is permeable to the solvent). (18 Nov 1997) |
| osmotic diuresis | Diuresis due to a high concentration of osmotically active substances in the renal tubules (e.g., urea, sodium sulfate), which limit the reabsorption of water. (05 Mar 2000) |
| osmotic diuretics | Drugs, such as mannitol, which by their osmotic effects retain water during urine formation and thus dilute electrolytes in the urine, making resorption less efficient; they promote the elimination of water and electrolytes in the urine. (05 Mar 2000) |
| osmotic fragility | The susceptibility, or lack of resistance, of erythrocytes to haemolysis when exposed to increasingly hypotonic saline solutions. (12 Dec 1998) |
| osmotic pressure | See: osmosis. The pressure required to prevent osmotic flow across a semi permeable membrane separating two solutions of different solute concentration. Equal to the pressure that can be set up by osmotic flow in this system. (18 Nov 1997) |
| osmotic shock | Passage of solvent into a membrane bound structure due to osmosis, causing rupture of the membrane. A method of lysing cells or organelles. (18 Nov 1997) |
| effective osmotic pressure | That part of the total osmotic pressure of a solution that governs the tendency of its solvent to pass across a boundary, usually a semipermeable membrane; it is commonly represented by the product of the total osmotic pressure of the solution and the ratio (corrected for activities) of the number of dissolved particles that do not permeate the bounding membrane to the total number of particles in the solution; equivalent in meaning to tonicity; commonly expressed in equivalent units of osmolality rather than pressure per se. (05 Mar 2000) |
| acute lobar nephrosis | A severe but localised bacterial infection of the renal parenchyma that may produce a mass effect simulating a renal abscess. (05 Mar 2000) |
| acute nephrosis | Acute oliguric renal failure, especially that caused by certain poisons. (05 Mar 2000) |
| amyloid nephrosis | The nephrotic syndrome due to deposition of amyloid in the kidney. See: renal amyloidosis. (05 Mar 2000) |
| bile nephrosis | <gastroenterology, nephrology> Acute renal failure occurring in a patient with liver failure. The exact causal relationship in unclear, but those with alcoholic cirrhosis and alcoholic hepatitis are at greatest risk. Symptoms include decreased or absent urine production, jaundice, abdominal swelling, delirium, confusion, nausea and vomiting. Prognosis is very poor. (27 Sep 1997) |
| vacuolar nephrosis | Vacuolation of the epithelial cytoplasm of renal convoluted tubules in patients seriously depleted of potassium; vacuoles do not contain fat or glycogen, concentrating ability is impaired, polyuria and polydipsia are common, and pyelonephritis may develop. Synonym: vacuolar nephrosis. (05 Mar 2000) |
| cholaemic nephrosis | An obsolete term for the occurrence of acute renal failure in jaundiced patients; the kidneys contain tubular casts of bile and may show tubular necrosis, but there is little evidence that jaundice or bile casts directly damage the kidneys. (05 Mar 2000) |
