Effect of LPS on step-through type passive avoidance test (A) and water maze test (B, C, D). (A), Each value is mean ± S.E. from 7–9 mice. *Significantly different from control (p < 0.05). Memory function was determined by the escape latencies (B, sec), distance (C, cm) and speed (D, cm/sec) for 3 days at 4 hr (designated 1 day) after administration of LPS. Each value is mean ± S.E. from 7–9 mice. *Significantly different from control (p < 0.05).
