摘要：
The alpha 7 receptor agonist dimethoxybenzylidene anabaseine (DMXB) protected rat neocortical neurons against excitotoxicity administered 24 h before, but not concomitantly with, NMDA. This action was blocked by nicotinic but not muscarinic antagonists. DMXB (1 mg/kg i.p.) also reduced infarct size in rats when injected 24 h before, but not during, focal ischemic insults. In a mecamylamine-sensitive manner, alpha 7 receptors appear neuroprotective in non-apoptotic model. (C) 1998 Elsevier Science B.V.
