Lead concentration in the hippocampus of P60–75 rats

Groups	Con (n = 8)	Lead (n = 8)	Con+Tau (n = 7)	Lead+ PW-Tau (n = 7)	Lead+ WL-Tau (n = 8)	Lead+ PL-Tau (n = 8)
Lead concentration in hippocampus(μg/g)	0.249 ± 0.096	1.514 ± 0.64^a	0.249 ± 0.143	0.475 ± 0.129^b	0.929 ± 0.094^c	0.502 ± 0.148^b

All the values are expressed as mean ± SEM; the number of experiments is shown in brackets (n =); ^asignificantly different from Con group (p < 0.01); ^bsignificantly different from Lead group (p < 0.01) and statistically indistinguishable from Con group (p > 0.05); ^csignificantly different from Lead (p < 0.01), Con (p < 0.01), Lead+PW-Tau (p < 0.05) and Lead+PL-Tau groups(p < 0.05). One-way ANOVA with the Bonferroni post hoc test were used for statistical analysis.
