Effect of astragalin on inflammation in brain I/R rats. a NF-κB (p65) and COX-2 protein expression levels. b Quantitative results of NF-κB (p65) protein expression. c Quantitative results of COX-2 protein expression. d NO levels in the brain of each group of rats. Data represent the average ± SD of three independent experiments for each bar. n = 10.Compared with the sham operation group, ##P < 0.01; compared with the I/R group, *P < 0.05, **P < 0.01
