Effect of CP and A/S on GLT-1, xCT and GLAST expression in the hippocampus (Hipp). (A, C, E) Immunoblots for GLT-1/ β-tubulin, xCT/ β-tubulin and GLAST/ β-tubulin, respectively. (B), (D) and (F) Statistical analysis revealed no change in the GLT-1, xCT or GLAST expression among Vehicle-Vehicle, CP-Vehicle and CP-A/S groups, (p > 0.05), (n = 6-7 for each group), values shown as means ± S.E.M, (V: Vehicle; A/S: Ampicillin/Sulbactam; CP: CP 55,940).
