Abstract
Salvianolate has been widely used for the treatment of cerebrovascular diseases. However, the detailed molecular mechanism of how it alleviates cerebral ischaemia-reperfusion injury is not well understood. In the present study, we investigated the neuroprotective effects of salvianolate in acute cerebral infarction using the PC12 cell oxygen-glucose deprivation (OGD) model in vitro and the rat transient middle cerebral artery occlusion (MCAO) model in vivo. The results showed that the salvianolate significantly reduced the level of reactive oxygen species and inhibited the Caspase-3 signalling pathway in vitro; at the same time, in vivo experiments showed that salvianolate obviously reduced the infarct area (12.9%) and repaired cognitive function compared with the model group (28.28%). In conclusion, our data demonstrated that the salvianolate effectively alleviated cerebral ischaemia-reperfusion injury via suppressing the Caspase-3 signalling pathway.
