Conclusion
UTI improves cerebral IR injury in rats potentially via decreasing the expression levels of AQP4.
Results
Compared with S group, the infarct volume, water content, neurological scores and AQP4 levels in the rat brain tissues were significantly increased in IR group. Administration of UTI significantly decreased the infarct volume, water content of the brain tissue and neurological scores. Moreover, the expression levels of AQP4 were also down-regulated by UTI treatment.
