Poster summary

We investigated the effect of early cadmium and aluminium co-exposures in neonatal mice. The study which comprised four groups of Control: A; AlCl3:B; CdCl2:C and AlCl3+CdCl2 :D. Weekly intraperitoneal treatment commenced on postnatal day 7 and lasted till postnatal day 35. Following behavioural phenotyping, on postnatal day 55-57, animals were sacrificed on PD 58 and brains were harvested. Brain regions (prefrontal cortex (PFC), stratum (ST) and hippocampus (HP)) were processed for oxido-inflammatory indices. Data was expressed as mean ± SD. P<0.05 was considered as statistically significant using a one-way ANOVA followed by Bonferroni multiple comparison test. Our findings suggests that neonatal co-exposures of aluminium and cadmium induced behavioural modifications relative to hyper locomotion and memory deficits found in several neurodevelopmental pathologies. These behavioural modifications may have occurred in response to altered oxido-inflammatory balance in the mice brain.
