PREP increased in PCA rats is recovered to control level after ibuprofen treatment. Groups of 4–5 animals of control sham operated rats (left) and PCA rats (left), were administrated with 0, 5, 15 and 30 mg/kg for 4 days, and striatal PREP levels of activity (upper graph) and protein (lower graph) were measured in both groups. The shade of grey in the bars increases with the increase on ibuprofen dose as showed. Statistical p values between selected bars are shown
