Objective:To investigate the influence of edaravone on expression of VEGF
IL-1β and TNF-α in vascular cognitive impairment brain and the serum level of VEGF
IL-1β and TNF-α in vascular cognitive impairment rats
in order to study neuroprotection mechanism of edaravone against vascular cognitive impairment.Methods:The vacsular cognitive impairment rat model was established by permanent bilateral occlusion of both common carotid arteries.Behaviour was evaluated 2 weeks after permanent bilateral occlusion of both common carotid arteries with Morris water maze and shuttle box task.Wistar rats were randomly divided into sham-operation group(S)
vascular cognitive impairment model group(M)and edaravone treatment group(MT).Serum level and expression of IL-1β and TNF-α was measured by enzyme linked immunosorbent assay
VEGF by enzyme linked immunosorbent assay and western blotting.Results:Edaravone significantly improved cognitive impairment from permanent bilateral occlusion of both common carotid arteries.The serum level and expression of IL-1β and TNF-α in MT group were lower than these in M group(P<0.01).The serum level and expression of VEGF in MT group was higher than these in M group(P<0.01).The serum level and expression of VEGF
IL-1β and TNF-α in MT and M groups were higher than that of in S group(P<0.01).Conclusions:Edaravone can restrain the expression of IL-1β
TNF-α and increase the expression of VEGF in rats with vascular cognitive impairment.Edaravone can enhance recovery of vascular cognitive impairment to protect neural function by restraining neuroinflammation.
