Objective: To investigate the protective effect and mechanism of combined formula of Erigerontis Herba and Paeoniae Radix Rubra (Xinshao) on cerebral ischemia reperfusion injury in rats. Method: The rats were randomly divided into four groups:sham operation group
model group
nimodipine group (12.6 mg · kg-1) and Xinshao group (12.5 g · kg-1). Rats were administrated with drugs for 3 days; then the cerebral ischemia-reperfusion model was established by improved Zea longa method. After surgery
the rats were administrated with drugs for 7 days. The neurological behavior was evaluated by Zea Longa method.triphenyltetrazolium Chloride(TTC) staining was performed to determine the area of cerebral infarction. interleukin-6(IL-6)
IL-1β and tumor necrosis factor-α(TNF-α) levels in serum were examined by enzyme-linked immunosurbent assay(ELISA). The levels of phosphorylation of p65 and IκBα were detected by Western blot. Result: Compared with sham operation group
the score of neurological behavior and the percentage of infarct area were significantly increased in model group
which indicated the successful establishment of the MACO model. Xinshao could significantly ameliorate the neurological behavior (P<0.05)
and decrease the percentage of infarct area (P<0.05). Compared with model group
the levels of IL-6
IL-1β and TNF-α in serum were significantly lowered in Xinshao group (P<0.01). Western blot analysis showed that Xinshao could reduce the phosphorylation levels of p65 and IκBα (P<0.01). Conclusion: Xinshao has a protective effect on cerebral ischemia reperfusion injury in rats
which may be associated with the inhibition of nuclear transcription factor-κB(NF-κB) pathway.
