| 설명 | 혈액이나 소변에서 실시하는 검사항목. pH검사는 인체의 체액의 산성, 알칼리성을 알아보는 중요한 검사이다. 인체는 약알칼리성에 속하나, 이보다 pH의 증가나 감소가 나타날 경우, 생명에 위험이 발생한다. 인체내에는 이런 산도의 증감을 막기위해, 이른바 완충제들이 많이 존재하며, 특히 허파와 콩팥이 완충작용을 수행하는 주요기관이다. 콩팥은 산도가 높을 경우, 소변에서 산도를 증가시켜 배출함으로써 혈액내의 알칼리성 농도가 증가하도록 한다. 또한 허파에서도, 혈액내에 산도가 증가시 호흡을 증가함으로써 밖으로 산의 배출을 증가시킨다. 이런 허파와 콩팥의 균형은 아주 적절히 이루어지고 있으며, 어느 한 기관의 이상이 발생하면, 이런 균형은 깨어지기 쉽다. |

| ion exchange resin | <chemistry> A resin of polymers that havefixed charged groups which is used in chromatographic columns to separate ions. (27 Oct 1998) |
|---|---|
| ion exchange resins | <chemistry> High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ion exchange) with either cations or anions. See: ion exchange, ion exchanger. (12 Dec 1998) |
| chromatography, ion exchange | Separation technique in which the stationary phase consists of ion exchange resins. The resins contain loosely held small ions that easily exchange places with other small ions of like charge present in solutions washed over the resins. (12 Dec 1998) |
|---|---|
| ion exchange | Reversible chemical reaction between a solid, often an ion exchange resin, and a fluid whereby ions may be exchanged from one substance to another. This technique is used in water purification, in research, and in industry. (12 Dec 1998) |
| ion exchange chromatography | <procedure> Separation of molecules by absorption and desorption from charged polymers. An important technique for protein purification. For small molecules the support is usually polystyrene, but for macromolecules, cellulose, acrylamide or agarose supports give less non-specific absorption and denaturation. Typical charged residues are CM carboxymethyl) or DEAE (diethylaminoethyl). (27 Oct 1998) |
| anion exchange resin | <chemistry> A resin with fixed cationic groups which is used in chromatography to separate anionic molecules. A High molecular weight, insoluble polymers that contain functional anionic groups capable of undergoing exchange reactions. These resins are used for ion exchange chromatography, as gastric antacids, hypocholesteraemics, etc. (14 Aug 2000) |
| cation-exchange resin | See: cation exchange, cation exchanger. (05 Mar 2000) |
| anion exchange | The process by which an anion in a mobile (liquid) phase exchanges with another anion previously bound to a solid, positively charged phase, the latter being an anion exchanger. It takes place when Cl- is exchanged for OH- in desalting. The reaction is Cl- (in solution) + (OH- on anion exchanger+) → (Cl- on anion exchanger) + OH- (in solution); combined with cation exchange, NaCl is removed from solution. Anion exchange may also be used chromatographically, to separate anions, and medicinally, to remove an anion (e.g., Cl-) from gastric contents or bile acids in the intestine. (05 Mar 2000) |
| maternal-foetal exchange | Exchange of substances between the maternal blood and the foetal blood through the placental barrier. It excludes microbial or viral transmission. (12 Dec 1998) |
| cation exchange | The process by which a cation in a liquid phase exchanges with another cation present as the counter-ion of a negatively charged solid polymer (cation exchanger). A cation-exchange reaction in removal of the Na+ of a sodium chloride solution is RSO3-H+ + Na+ → RSO3-Na+ + H+ (R is the polymer, RSO3- is the cation exchanger); if this is combined with the anion-exchange reaction, NaCl is removed from the solution (desalting). Cation exchange may also be used chromatographically, to separate cations, and medicinally, to remove a cation; e.g., H+, from gastric contents, or Na+ and K+ in the intestine. See: anion exchange. (05 Mar 2000) |
| cation exchange resins | High molecular weight insoluble polymers which contain functional cationic groups that are capable of undergoing exchange reactions; used in various types of chromatography; also to treat hyperkalaemia. (12 Dec 1998) |
| respiratory exchange ratio | The ratio of the net output of carbon dioxide to the simultaneous net uptake of oxygen at a given site, both expressed as moles or STPD volumes per unit time; in the steady state, respiratory exchange ratio is equal to the respiratory quotient of metabolic processes. (05 Mar 2000) |
| charge exchange | <radiobiology> Phenomenon in which an ion colliding with a molecule (or an atom) neutralises itself by capturing an electron from the molecule or atom, and transforming the molecule or atom into a positive radical or ion. (13 Nov 1997) |
| plasma exchange | Removal of plasma and replacement with various fluids, e.g., fresh frozen plasma, plasma protein fractions (ppf), albumin preparations, dextran solutions, saline. Used in treatment of autoimmune diseases, immune complex diseases, diseases of excess plasma factors, and other conditions. (12 Dec 1998) |
| pulmonary gas exchange | The exchange of oxygen and carbon dioxide between alveolar air and pulmonary capillary blood. (12 Dec 1998) |
| sister chromatid exchange | An aberrant crossing-over event in which there is an exchange of segments between the sister chromatids of a chromosome, either between the sister chromatids of a meiotic tetrad or between the sister chromatids of a duplicated somatic chromosome. It can be induced by ultraviolet and ionizing radiation or by mutagenic agents and is observed by autoradiography. (12 Dec 1998) |
| needle-exchange programs | Organised services for exchange of sterile needles and syringes used for injections as a potential means of reducing the transmission of infectious diseases. (12 Dec 1998) |
