Effect of paeonol on inflammatory factors after focal cerebral ischemia-reperfusion injury in rats / 中国生化药物杂志

ABSTRACT

Purpose To observe the effect of paeonol on inflammatory factors after focal cerebral ischemiareperfusion injury in rats and its possible mechanism of paeonol.Methods Focal cerebral ischemic model was established by MCAO in rats.After 2 hours of cerebral ischemia and 22 hours of reperfusion,the expression of TNF-α and IL-1β in brain was determined by immunohistochemistry.The content of TNF-α and IL-1β in serum was measured by ELISA.Results Compared with model group,the levels of TNF-α and IL-1β in brain and serum in rats in the paeonol groups were obviously decreased.Conclusion Paeonol could relieve brain damage induced by focal cerebral ischemia-reperfusion,which may be related to inhibiting the production of inflammatory factors.
