Results from behavioral analysis. In A, B and C, means of crossing, rearing and defecations, respectively, in the open field test at 1 and 15 days after the surgical microinjections of vehicle (Control) or 6-hydroxydopamine (6-OHDA) into dorsal striatum of rats (n = 8). In D, results of the cylinder test. Columns represent the mean e and bars indicate the SEM. DTTS: dry tea of Tradescantia spathacea at 10, 30 and 100 mg/kg in distillated water, p.o., during 30 days. * indicates significant difference from Control group (being * p < 0.05; **p < 0.01; ***p < 0.001 and ****p < 0.0001), # indicates significant difference from 6-OHDA (#p < 0.05 and ###p < 0.001), and + indicates significant difference from DTTS 10 (p < 0.05). Two-way analysis of variance with Bonferroni's post-tests.
