Effects of lead, DSP-4 and L-DOPA treatment on motor coordination assessed by the rotarod test. (A) Motor coordination histograms represent the time spent on the rotarod bar in control and lead treated rats. (B) Histograms showing the comparison of the time spent on the rotarod bar in control, lead and DSP-4 rats on day 56. (C) Histograms showing the effect of L-DOPA in lead and DSP-4 rats. Values are the mean ± SEM. Data from controls and lead rats on (A) were compared using the two-way ANOVA followed by Sidak's post-hoc test. Data from controls (n = 6), lead (n = 6), and DSP-4 rats (n = 6) on (B) were compared using the one-way ANOVA followed by Tukey's post-hoc test. Data from lead (n = 6) and DSP-4 (n = 6) rats on (C) were compared using the Mann whitney test. *P < 0.05, **P < 0.01, ***P < 0.001, NS, no significant.
