Fig. 2From: Intraventricular infusion of quinolinic acid impairs spatial learning and memory in young rats: a novel mechanism of lead-induced neurotoxicityNumber of quinolinic acid immunoreactive cells/field in cortex (a), CA1 (b), CA3 (c), dentate gyrus (d), and thalamus (e) regions in Pb-exposed and control groups at PND45 and PND60. Data were analyzed with one-way ANOVA with Bonferroni multiple comparisons test (n = 4 in all groups). Note Pb-exposed rats had significantly higher number of QA-immunoreactive cells in all regions studied at both PND45 and PND60 compared to control group except in thalamus at PND45 (* p < 0.05)Back to article page
