ZRS promoted brain injury amelioration and improved nerve function and behavioural performance. A TTC staining showing infarct volumes 7 days after surgery. Normal brain tissue appears red, and infarcted tissue appears pale grey. B Neurological deficit scores in the three groups were assessed by the Longa scale scoring system 2 h, 3 days, 7 days, and 14 days after reperfusion. *P < 0.05 versus Veh group, n = 10 per group. C Quantitative analysis of brain infarct volumes in vehicle- and ZRS-treated rats 1, 3, and 7 days after MCAO. *P < 0.05, **P < 0.01 versus Veh group, n = 6 per group
