| 영문 | hemolysis | 한글 | 용혈 |
|---|---|---|---|
| 설명 | 혈액 속의 적혈구만이 어떤 원인에 의하여 파괴되어 안에 있는 혈색소가 유출되는 현상. 적혈구가 깨지는 원인은 여러 가지가 있다. 생리식염수 등으로 부유시킨 적혈구가 전부 녹으면 불투명하고 흰빛이 도는 적색을 띤 부유액은 붉은 잉크 모양의 투명한 액이 되어 육안으로도 잘 볼 수 있지만 용액의 정도가 50~60% 이하일 때는 그대로는 알기 어렵다. |

| 영문 | osmotic pressure | 한글 | 삼투압 |
|---|---|---|---|
| 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. |

| 영문 | osmotic fragility | 한글 | 삼투압취약성 |
|---|---|---|---|
| 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. |

| hemolysis | <haematology> Disruption of the integrity of the red cell membrane causing release of haemoglobin. Haemolysis may be caused by bacterial haemolysins, by antibodies that cause complement dependent lysis, by placing red cells in a hypotonic solution or by defects in the red cell membrane. Origin: Gr. Lysis = dissolution (18 Nov 1997) |

| 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 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) |
| 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) |
| bovine colloid | <protein> Protein present in serum that causes agglutination of antibody antigen complement complexes, binds C3b. (18 Nov 1997) |
| radiogold colloid | A radioactive isotope of gold emitting negative beta particles and gamma radiation, with a half-life of 2.7 days; formerly used for irradiation of closed serous cavities in the palliative treatment of ascites and pleural effusion due to metastatic malignancies, and for liver scans. Synonym: 198Au colloid, colloidal radioactive gold. (05 Mar 2000) |
| gold colloid | A purplish suspension of minute particles of metallic gold, made by reducing a solution of bromauric acid or other acid or salt of gold. It is used as a probe in immunochemistry. (12 Dec 1998) |
| gold colloid, radioactive | <chemical> A radioactive suspension of minute particles of metallic gold, made by exposure to neutrons. It is used in the pleural cavity to treat lung cancer. Pharmacological action: antineoplastic agent, radiopharmaceuticals. (12 Dec 1998) |
| colloid osmotic hemolysis |
The swelling and rupture of red blood cells when they become excessively permeable to sodium and fill with water.
