Exogenous H2S reverses impaired cognitive function without altering locomotor performance, which is similar to L-NAME. a and b Locomotor activity was assessed using the OFT on Day 2 post-surgery and the total moving distance and moving duration were measured. c and d Spatial learning ability was evaluated using the MWM on Days 3 to 7 post-surgery, and the escape latency and path length were measured. e and f Spatial memory capacity was assessed using the MWM on Day 8 post-surgery, and the percent time and length in the target quadrant were measured. * P < 0.05, compared with the sham group; ** P < 0.01, compared with the sham group; # P < 0.05, compared with the surgery group; ## P < 0.01, compared with the surgery group
