Effect of H₂S on the spatial orientation learning ability of mice. After treatment with saline or NaHS (30 and 100 µmol/kg/day, intraperitoneally) for 11 days followed by co-treatment with TAA (150 mg/kg, intraperitoneally) for 3 days, respectively, the mice were subjected to the Y-maze test. (A) The total number of arm entries and (B) spontaneous alternations were recorded. Values are presented as the mean ± SEM. n=9-15. ^*P<0.05 vs. control; ^##P<0.01 vs. TAA. H2S, hydrogen sulfide; TAA, thioacetamide; NaHS, sodium hydrogen sulfide.
