Potassium-evoked and amphetamine-evoked overflow of DA from the striatum of young adult, middle-aged and aged animals injected in the right striatum with 6-OHDA four weeks prior to treatment with vehicle or calcitriol. Microdialysis experiments were performed three weeks after the last vehicle or calcitriol injection. The results are expressed as percentage of DA overflow on the lesioned side compared to the contralateral, unlesioned side. Values shown are mean ± SEM from 7–8 animals per group. * p < 0.05 vs. vehicle treated group of the same age (two-way ANOVA with age and treatment group as between factors; followed by Newman-Keuls post-hoc comparisons).
