Effects on cholinergic markers in rat brain and blood after short and prolonged administration of donepezil.

abstract：:Many studies have demonstrated that apoptosis play an important role in cerebral ischemic pathogenesis and may represent a target for treatment. Neuroprotective effect of quercetin has been shown in a variety of brain injury models including ischemia/reperfusion. It is not clear whether BDNF-TrkB-PI3K/Akt signaling pa...
