Effect of sulindac sulfide on the LPS-induced memory impairment (A-C) and elevated Aβ1–42 level (D). Sulindac sulfide was pretreated for 3 weeks by oral administration. For the passive avoidance performance test, mice were trained one time. At 24 hr later, mice were given LPS (250 μg/kg, i.p.). After 4 hr treatment of LPS, the latency period was measured. Each value is means ± S.E. from 15 mice. *Significantly different from LPS treated control (p < 0.05). (B-C), Mice were pretreated with Sulindac sulfide for 3 weeks, and then trained for 3 days (2 times/day, 6 times training), and then LPS (250 μg/kg, i.p.) was administered into mice. Memory function was determined by the escape latencies (cm, B) and distance (sec, C) at 4 hr (designated day 1). Each value is means ± S.E. from 15 mice. D, The levels of Aβ1–42 were assessed after finishing the behavioral tests by using a specific Aβ1–42 ELISA. Values measured from each group of mice were calibrated by amount of protein and expressed as mean ± S.E. (n = 15) *Significant different from LPS treated group (p < 0.05).
