PG - 825-34 LID - 10.3233/NRE-141177 [doi] AB - BACKGROUND: Due to the lack of efficient neuroprotective therapies, the ischemia-reperfusion (I/R) injury is a major medical problem urgently needed to be further studied. OBJECTIVE: To investigate the neuro-protective effects of propofol-dexmedetomidine (dex) combination on I/R-induced cerebral injury and potential mechanisms. METHODS: Sprague-Dawley rats were randomized to sham-operated, I/R, I/R plus propofol, I/R plus dex, and I/R plus propofol-dex combination group. I/R insult was induced by 2 h middle cerebral artery occlusion (MCAO) followed by 24 h reperfusion; Drugs were administered 20 min before the onset of ischemia and continued for another 2 h. Functional outcomes, the expression of Superoxide dismutase (SOD), Methane Dicarboxylic Aldehyde (MDA), Tumor necrosis factor-alpha (TNF-alpha), Interleukin-1beta (IL-1beta), caspase-3 and protein kinase B (AKT) were tested. RESULTS: Propofol-dex combination significantly mitigates I/R-induced neurological deficits in model rats compared to dex or propofol infusion alone. The decreased activity of SOD was significantly reversed following co-administration of propofol and dex, along with the down-regulated MDA content. Perioperative treatment with propofol and dex significantly suppressed I/R-up regulated TNF-alpha and IL-1beta expressions, ameliorated AKT1 expression and caspase-3 activity. CONCLUSION: Propofol-dex combination exerted a stronger neuro-protection against I/R injury when compared with propofol or dex alone.
