| 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 | <chemistry, radiobiology> Atomic particle, atom or chemical radical bearing an electric charge, either negative or positive. (16 Dec 1997) |
|---|---|
| ion channel | <cell biology> A transmembrane pore that presents a hydrophilic channel for ions to cross a lipid bilayer down their electrochemical gradients. Some degree of ion specificity is usually observed and typically a million ions per second may flow. Channels may be permanently open, like the potassium leak channel or they may be voltage gated, like the sodium channel or ligand gated like the acetylcholine receptor. (27 Oct 1998) |
| ion channel gating | The opening and closing of ion channels due to a stimulus. The stimulus can be a change in membrane potential (voltage-gated), drugs or chemical transmitters (ligand-gated), or a mechanical deformation. Gating is thought to involve conformational changes of the ion channel which alters selective permeability. (12 Dec 1998) |
| ion channels | Gated, ion-selective glycoproteins that traverse membranes. The stimulus for channel gating can be a membrane potential, drug, transmitter, cytoplasmic messenger, or a mechanical deformation. Ion channels which are integral parts of ionotropic neurotransmitter receptors are not included. (12 Dec 1998) |
| ion cyclotron emission | <radiobiology> As ions gyrate around in a magnetic field (see also larmor radius or cyclotron radius), they radiate radio-frequency electromagnetic waves. This is known as ion cyclotron emission, and can be measured to help diagnose a plasma. (09 Oct 1997) |
| ion diode | <radiobiology> Device for producing and accelerating ion beams for light ion drivers for inertial confinement fusion. Ions are produced in an anode plasma, extracted as space-charge-limited ion flow, and accelerated to the cathode, composed of a confined electron swarm, by an applied electric field. Millions of amperes of current at millions of volts have been produced this way. (27 Oct 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) |
| 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) |
| ion exchanger | See: anion exchanger, cation exchanger. (05 Mar 2000) |
| ion pump | A membranal complex of proteins that is capable of transporting ions against a concentration gradient using the energy from ATP. (05 Mar 2000) |
| ion pumps | Integral membrane proteins that transport ions across a membrane against an electrochemical gradient. (12 Dec 1998) |
| ion selective electrode | An electrode half cell, with a semi permeable membrane that is permeable only to a single ion. The electrical potential measured between this and a reference half cell (e.g. A calomel electrode) is thus the Nernst potential for the ion. Given that the solution filling the ion selective electrode is known, the activity (rather than concentration) of the ion in the unknown solution can be measured. Commercial ion selective electrodes frequently use a hydrophobic membrane containing an ionophore, such as valinomycin (for potassium) or monensin (for sodium). A pH electrode is made with a thin membrane of pH sensitive (i.e. Proton permeable) glass. (18 Nov 1997) |
| ion transport | The movement of ions across energy-transducing cell membranes. Transport can be active or passive. Passive ion transport (facilitated diffusion) derives its energy from the concentration gradient of the ion itself and allows the transport of a single solute in one direction (uniport). Active ion transport is usually coupled to an energy-yielding chemical or photochemical reaction such as ATP hydrolysis. This form of primary active transport is called an ion pump. Secondary active transport utilises the voltage and ion gradients produced by the primary transport to drive the cotransport of other ions or molecules. These may be transported in the same (symport) or opposite (antiport) direction. (12 Dec 1998) |
| Alfven ion cyclotron instability | <radiobiology> An electromagnetic microinstability near the ion cyclotron frequency, driven by the ion loss cone in a mirror device. Acronym: AIC (13 Nov 1997) |
|---|---|
| aquo-ion | A hydrated ion; an ion containing one or more water molecules; e.g., Cu(H2O)42+. (05 Mar 2000) |
| gated ion channel | <physiology> Transmembrane proteins of excitable cells, that allow a flux of ions to pass only under defined circumstances. Channels may be either voltage gated, such as the sodium channel of neurons or ligand gated such as the acetylcholine receptor of cholinergic synapses. Channels tend to be relatively ion specific and allow fluxes of typically 1000 ions to pass in around 1ms, they are thus much faster at moving ions across a membrane than transport ATPases. (05 May 1997) |
| central metal ion | <chemistry> The metal ion to which the ligands are attached at the centre of a coordination complex. (09 Oct 1997) |
| voltage gated ion channel | <physiology> A transmembrane ion channel whose permeability to ions is extremely sensitive to the transmembrane potential difference. These channels are essential for neuronal signal transmission and for intracellular signal transduction. See: sodium channel. (18 Nov 1997) |
| gram-ion | <chemistry> The weight in grams of an ion that is equal to the sum of the atomic weights of the atoms making up the ion. (05 Mar 2000) |
| 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) |
| mobile ion carrier | <chemistry> A molecule that allows ions to cross lipid bilayers. There are two classes: carriers and channels. Carriers, like valinomycin, form cage like structures around specific ions, diffusing freely through the hydrophobic regions of the bilayer. Channels, like gramicidin, form continuous aqueous pores through the bilayer, allowing ions to diffuse through. See: ion channels. (18 Nov 1997) |
| common ion effect | <chemistry> The influence on an equilibrium by the presence of a substance which contains ions that participate in the equilibrium. (09 Oct 1997) |

| hydride ion | The H- i., transferred to acceptor molecules in some biological oxidations. (05 Mar 2000) |

| hydronium ion | <chemistry> A positively charged ion that is water with an additional hydrogen atom (H3O). (09 Oct 1997) |
