摘要：

Objective: Stroke is the second leading cause of death worldwide. This study aimed to investigate the neuroprotective effect of Paeoniae Radix Rubra(PRR) on ischemic stroke of mice.Methods: The focal ischemic stroke model was produced via middle cerebral artery occlusion. The experimental mice were divided into four groups: vehicle-sham group, PRR-sham group, vehicle-ischemia group, and PRR-treated ischemia group. The cerebral infarction volume was detected with TTC staining.The number of neurons in the hippocampal CA1 of the ischemic side, and the activation of astrocytes and microglia were observed via immunohistochemical staining. Western blotting was used to determine the expression changes of SOD1, SOD2, and Catalase protein levels in the hippocampus.Results: PRR significantly reduced the cerebral infarct volume induced by ischemic injury and inhibited the astrocytes and microglia activation in the hippocampal CA1 region. The decreased levels of SOD1,SOD2, and Catalase that was induced by ischemic reperfusion were simultaneously improved after PRR treatment.Conclusion: PRR improved neuronal injuries that were induced by transient cerebral ischemia via inhibiting gliosis and elevating anti-oxidants.
