Figure 1: (a) Barnes maze acquisition escape time (s) of experimental animals following oral administration of Pb2⁺ and Curcuma longa. n = 6; mean ± SEM, two-ways repeated measures ANOVA, Tukey post hoc test. ^aP < 0.05 when compared to control, ^bP < 0.05 when compared to Pb2⁺. (b) Barnes maze probe test escape time (s) of experimental animals following oral administration of Pb2⁺ and Curcuma longa. n = 6; mean ± SEM, one-way ANOVA, Tukey post hoc test. ^aP < 0.05 when compared to control, ^bP < 0.05 when compared to Pb2⁺. (c) Barnes maze acquisition wrong trials of experimental animals following oral administration of Pb2⁺ and Curcuma longa. n = 6; mean ± SEM, two-ways Repeated measures ANOVA, Tukey post hoc test. ^aP < 0.05 when compared to control, ^bP < 0.05 when compared to Pb2⁺. (d) Barnes maze probe test wrong trials (n) of experimental animals following oral administration of Pb2⁺ and Curcuma longa. n = 6; mean ± SEM, Kruskal − Wallis test, Dunn's post hoc test. ^aP < 0.05 when compared to control, ^bP < 0.05 when compared to Pb2⁺.
