Effects of glibenclamide on memory in rats with sevoflurane-induced cognitive impairment as demonstrated by the Y maze test. Values are presented as (A) mean ± SEM (n = 15) of total arm entries and (B) percentage of spontaneous alternations: # – p < 0.05 and ## – p < 0.01 for significant difference versus the control group; * – p < 0.05 for significant difference versus the low-dose sevoflurane group; GBC – glibenclamide; LDS – low-dose sevoflurane
