Abstract:
Objective To explore the effect and mechanism of curcumin on rat cerebral ischemia reperfusion injury.Methods The rat model of cerebral ischemia reperfusion injury was constructed by the suture-occluded method.The effects of curcumin on cerebral infarction range,cerebral water content,neurological symptoms,cerebral histopathological morphology and expressions of PI3K,AKT,p-AKT,m-TOR,MDA,CAT,GPX,SOD,Bcl-2,Bax,Caspase-3 and Cleavage-Caspase-3 were evaluated.Results Cur-cumin had the protective effect on cerebral ischemia reperfusion injury,could alleviate the neurological symptoms,decreased the cer-ebral tissue pathological morphological changes and cerebral water content,in addition,which could alleviate the expressions of MDA,Bax,Cleavage-Caspase-3,IL-6,MCP-1 and TNF-αand increased the expressions of PI3K,p-AKT,mTOR,Bcl-2,Caspase-3, CAT,GPX and SOD.Conclusion The curcumin pretreatment has the significantly protective effect on cerebral ischemia-reperfusion injury,which may be associated with activating PI3K/AKT/mTOR signal pathway,while suppressing inflammation,apoptosis and oxidative stress.
