Abstract
Tetramethylpyrazine (TMP) has been studied in depth and is widely used in the treatment of many kinds of diseases in China. However, whether it has neuroprotective effects on cerebral ischemia remains unclear. An ischemia/reperfusion (I/R) injury animal model was established via middle cerebral artery occlusion in this study. We set several different groups in which the rats were performed in different ways to explore the effects of TMP on blood-brainbarrier (BBB) disruption and determine whether TMP relieved BBB disruption through blocking the JAK/STAT signaling pathway. Our results showed that TMP could reduce the neurological functional loss, decrease the brain edema and BBB permeability, as well as increase the expression of tight junction proteins via inhibiting the activation of JAK/STAT signaling pathway. Overall, we demonstrated that TMP promoted neurological recovery after I/R injury via restoring the integrity and function of BBB.Entities:
