Aluminium exposure has been linked with developmental neurotoxicity in humans and experimental animals.The study aimed to evaluate the ameliorative effect of Tamarindus indica on the developing cerebellar cortex, neurobehavior, and immunohistochemistry of the cerebellar cortex following prenatal aluminum chloride (AlCl3) exposure. Pregnant timed Wistar rats were divided into 5 groups (n=4). Group I (negative control) was given distilled water, group II was treated with 200 mg/kg of AlCl3, group III were given 200 mg/kg of AlCl3 and 400 mg/kg of ethyl acetate leaf fraction of Tamarindus indica (EATI), group IV were given 200 mg/kg of AlCl3 and 800 mg/kg of EATI, and group V were treated with 200 mg/kg of AlCl3 s/c and 300 mg/kg of vitamin E for 14 days (prenatal day 7–21) via the oral route. Male pups (n=6) were randomly selected and taken for neurobehavioral studies, and humanely sacrificed via intraperitoneal injection of thiopental sodium. The cerebellum was removed, fixed and tissue processed for histological and immunohistochemical studies. The results revealed that prenatal AlCl3 exposure impacted neurodevelopment and neurobehaviour among exposed pups. Prenatal AlCl3 exposure was marked with delayed cytoarchitectural development of the cerebellar cortex and increased GFAP expression inthe cerebellar cortex. On the other hand, treatment with EATI and vitamin E were marked with significant improvements.The present study therefore concluded treatment with EATI shows an ameliorative effect to prenatal AlCl3 exposure.
