| LAN | local area network; long-acting neuroleptic [agent] |
| LAS | laboratory automation system; lateral amyotrophic sclerosis; laxative abuse syndrome; left anterior-... |
| LCBF | local cerebral blood flow |

| neoplasm recurrence, local | The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site. (12 Dec 1998) |

| local | Restricted to or pertaining to one spot or part, not general. Origin: L. Localis (18 Nov 1997) |
| local anaemia | Anaemia resulting from a decreased supply of blood to a part, as in the occlusion of a vessel. (05 Mar 2000) |
| local anaesthesia | The use of a local anaesthetic (usually injected into the tissue) results in a small region of anaesthesia (numbness). Lidocaine (Xylocaine) or (Marcaine) are commonly used. Origin: Gr. Aisthesis = sensation (27 Sep 1997) |
| local anaesthetic | The use of a local anaesthetic (usually injected into the tissue) results in a small region of anaesthesia (numbness). Lidocaine (Xylocaine) or (Marcaine) are commonly used. (27 Sep 1997) |
| local anaesthetic reaction | A toxic reaction due to absorption of local anaesthetic drug during regional anaesthesia, ranging from drowsiness to convulsions and cardiovascular collapse. (05 Mar 2000) |
| local anaesthetics | Drugs used for the interruption of the nerve transmission of pain sensations. They act at the site of application to prevent perception of pain; examples include procaine and lidocaine. (05 Mar 2000) |
| local anaphylaxis | The immediate, transient kind of response that follows the injection of antigen (allergen) into the skin of a sensitised individual and is limited to the area surrounding the site of inoculation. See: skin test. (05 Mar 2000) |
| local area networks | Communications networks connecting various hardware devices together within or between buildings by means of a continuous cable or voice data telephone system. (12 Dec 1998) |
| local asphyxia | Stagnation of the circulation, sometimes resulting in local gangrene, especially of the fingers; one of the symptoms usually associated with Raynaud's disease. (05 Mar 2000) |
| local bloodletting | Removing blood from the smaller vessels, formerly by a cupping glass or by leeching. (05 Mar 2000) |
| local circuit theory | <physiology> A generally accepted model for neuronal conduction, by which depolarisation of a small region of a neuronal plasma membrane produces transmembrane currents in the neighbouring regions, tending to depolarise them. As the sodium channels are voltage gated, the depolarisation causes further channels to open, thus propagating the action potential. (18 Nov 1997) |
| local death | Death of a part of the body or of a tissue by necrosis. (05 Mar 2000) |
| local epilepsy | Epilepsy of various aetiologies characterised by focal seizures or secondarily generalised tonic-clonic seizures. Ictal symptoms are often related to the brain region where the seizure begins focally. Synonym: cortical epilepsy, local epilepsy, partial epilepsy. (05 Mar 2000) |
| local excitatory state | Increased irritability of a nerve fibre or muscle fibre which is produced by an ineffective electrical stimulus; summation of the stimuli may occur, resulting in a propagated impulse if two or more subliminal stimuli are applied in rapid succession. (05 Mar 2000) |
