Effects of PLA treatment on locomotor activity. Rats were randomly grouped and then treated with PLA (25, 50 and 75 mg/kg) or vehicle for 6 weeks after LPS injection. On day 42, rats were placed into open-field apparatus, and spontaneous behaviors of 30 min was measured and analyzed by a Tru Scan 2.01 software. a total movement distance; b total movement time; c total rest time; d horizontal velocity. n = 10–11. *** P < 0.001 vs. sham group, ## P < 0.01, ### P < 0.001 vs. LPS group
