Figure 7.

A, B, Digitized autoradiographic images (A) and quantitative analysis (B) showing the effects of separate or combined unilateral 6-hydroxydopamine lesion and Pf-HFS on striatal PPE mRNA expression. The data presented in the graphs are the means ± SEM of the optical density values determined from n animals per condition and are expressed as the percentages of control. Statistical comparison was performed using a one-way ANOVA followed by Student–Newman–Keuls test. Scale bar, 2 mm. ●, Side ipsilateral to surgery. **p < 0.01 compared with control values; ^@p < 0.05 compared with 6-OHDA lesion values.
