F Averaged use times of the right forelimb in each subgroup of rats at each time point. G Photographs of the Food Pellet-taking Test in each subgroup of rats. H Averaged IBB scores in each subgroup of rats at 8 weeks postsurgery. The data shown are the mean ± SD in each group; ***P < 0.001, **P < 0.01, *P < 0.05. NS normal saline, NAG acetylglutamine
