Quantification of tyrosine hydroxylase (TH)+ cells in control and experimental groups (treated with 100 µM of 6-hydroxydopamine, 6-OHDA).
(A) comparison of control with experimental groups (1, 3, and 5 days of exposure to 6-OHDA). The results showed reduction in TH+ cells in all experimental groups compared with the controls. (B) comparison of treated groups with each other revealed decreases in TH+ cells during the course of the experiment.
