Fig 2. The influence of 6-OHDA, pramipexole and imipramine on BDNF mRNA in the hippocampus.

The results are expressed as the mean ± S.E.M. LESION—lesioned rats, IMI—imipramine, PRA—pramipexole, Q-B/pixel2—the mean optical density-background per area units, SAL—saline, SHAM—sham-operated rats, n = 7–10, differences between SHAM-SAL vs. other groups are indicated by *p≤0.05, and differences between LESION-SAL vs. other groups by #p≤0.05).
