| exchange transfusion | Removal of most of a patient's blood followed by introduction of an equal amount from donors. Synonym: exsanguination transfusion, substitution transfusion, total transfusion. (05 Mar 2000) |
|---|---|
| exchange transfusion, whole blood | Repetitive withdrawal of small amounts of blood and replacement with donor blood until a large proportion of the blood volume has been exchanged. Used in treatment of foetal erythroblastosis, hepatic coma, sickle cell anaemia, disseminated intravascular coagulation, septicaemia, burns, thrombotic thrombopenic purpura, and fulminant malaria.

| 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) |
| 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) |
| complex ion | The colour, texture, and general appearance of the skin of the face. Origin: L. Complexio, a combination, (later) physical condition (05 Mar 2000) Previous: complex carbohydrate, complex closure, complex febrile convulsion, complexinNext: complex ion, complexity, complex learning processescomplex ion <chemistry> An ion formed by the combination of a central metal ion and ligands.

| Heavy Ion Beams | <radiobiology> Particle beams using heavy (as opposed to light) ions. These can be used for inertial confinement fusion research. (10 Jan 1998) |

| hydride ion | The H- i., transferred to acceptor molecules in some biological oxidations. (05 Mar 2000) |
| hydrogen ion | A hydrogen atom minus its electron and therefore carrying a unit positive charge (i.e., a proton); in water, it combines with a water molecule to form hydronium ion, H3O+. (05 Mar 2000) |
| ion exchanger |
A permanent, insoluble material which contains ions that will exchange reversibly with other ions in a surrounding solution. Both cation and anion exchangers are used in water conditioning.

| ion exchange |
A reversible process in which ions are released from an insoluble permanent material in exchange for other ions in a surrounding solution; the direction of the exchange depends upon the affinities of the ion exchanger for the ions present, and the concentrations of the ions in the solution.

| ion exchange c. |
that in which the stationary phase is an ion exchange resin. The mobile phase is an aqueous buffer solution that determines the degree of ionization of the sample components and thus their affinity for the stationary phase.

| ion exchange r. |
a high molecular weight, insoluble polymer of simple organic compounds with the ability to exchange its attached ions for other ions in the surrounding solution. They are classified as (a) cation or anion exchange resins, depending on which ions the resin exchanges, and (b) carboxylic, sulfonic, etc., depending on the nature of the active groups.
