| potassium channel | Ion channel selective for potassium ions. There are diverse types with different functions, for example: delayed rectifier channels, M channels, A channels, inward rectifier channels, Ca dependent K channels. (18 Nov 1997) |
|---|---|
| single channel recording | Variant of patch clamp technique. (18 Nov 1997) |
| slow channel-blocking agent | calcium channel-blocking agent |
| delayed rectifier channel | <physiology> The potassium selective ion channels of axons, so called because they change the potassium conductance with a delay after a voltage step. The name is used to denote any axon like K channel. Various roles for example regulation of pacemaker potentials, generation of bursts of action potentials or generation of long plateaus on action potentials. (18 Nov 1997) |
| double-channel catheter | A catheter with two lumens, allowing irrigation and aspiration. Synonym: two-way catheter. (05 Mar 2000) |
| 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) |
| transnexus channel | A hexagonal 15-20A |
| ligand-gated channel | A class of ion channel's whose ionic permeability is regulated by cell membrane receptors that respond to specific extracellular chemical signals. (05 Mar 2000) |
| ligand gated ion channel | A transmembrane ion channel whose permeability is increased by the binding of a specific ligand, typically a neurotransmitter at a chemical synapse. The permeability change is often drastic, such channels let through effectively no ions when shut, but allow passage at up to 10exp7 ions sexp 1 when a ligand is bound. Recently, the receptors for both acetylcholine and GABA have been found to share considerable sequence homology, implying that there may be a family of structurally related ligand gated ion channels.

| acetosulfone sodium | 2-N-Acetylsulfamyl-4,4'-diaminodiphenylsulfone;a leprostatic administered orally. (05 Mar 2000) |
| acetrizoate sodium | Salt of 3-acetamido-2,4,6-triiobenzoic acid, a formerly used water-soluble radiographic contrast medium. (05 Mar 2000) |
| antimony sodium gluconate | <chemical> Antimony complex where the metal may exist in either the pentavalent or trivalent states. The pentavalent gluconate is used in leishmaniasis. The trivalent gluconate is most frequently used in schistosomiasis. Pharmacological action: antiprotozoal agents, schistosomicides. (12 Dec 1998) |
| antimony sodium tartrate | Na(SbO)C4H4O6;used in the treatment of schistosomiasis, and as an emetic. Synonym: sodium antimonyl tartrate. (05 Mar 2000) |
| antimony sodium thioglycollate | A compound of antimony trioxide and thioglycolic acid, used for tropical parasites. (05 Mar 2000) |
