The present study aimed to observe cortical expression of Bcl-2 and Bax,cysteine-dependent aspartate directed proteases-3 activity and apoptotic cell death in a rat model of middle cerebral artery occlusion pretreated with propofol.Results showed that,propofol pretreatment significantly reduced oxidative stress levels and attenuated neuronal apoptosis in the cortex of rats.Propofol pretreatment upregulated Bcl-2 expression,and downregulated Bax expression and cysteine-dependent aspartate directed proteases-3 activity.These findings indicate that propofol pretreatment inhibits cell apoptosis during focal cerebral ischemia/reperfusion injury.This neuroprotective effect is most likely achieved through the Bcl-2/Bax/cysteine-dependent aspartate directed proteases-3 pathway.

Results indicate that, propofol pretreatment significantly reduced oxidative stress levels and attenuated neuronal apoptosis in the cortex of rats .ropofol pretreatment upregulated Bcl-2 expression, and downregulated Bax expression and cysteine-dependent aspartate directed proteases-3 activity. These findings that propofol pretreatment inhibits cell apoptosis during focal cerebral ischemia / reperfusion injury. This neuroprotective effect is most likely achieved through the Bcl-2 / Bax / cysteine-dependent aspartate directed proteases-3 pathway.
