dc.description.abstract | Ethnopharmacological relevance: Amburana cearensis (Allemao) A.C.Sm. is a medicinal plant of the Brazilian
Caatinga reported to present antioxidant and anti-inflammatory activity. This study aimed to evaluate the
neuroprotective effect of the extracts obtained from the seeds of A. cearensis in primary cultures of cerebellar
cells subjected to excitotoxicity induced by glutamate and brain mitochondria submitted to oxidative stress.
Materials: and methods: Primary cultures of cerebellar cells were treated with the ethanol (ETAC), hexane
(EHAC), dichloromethane (EDAC) and ethyl acetate (EAAC) extracts of the seeds of A.cearensis and subjected
to excitotoxicity induced by glutamate (10 μM). Mitochondria isolated from rat brains were submitted to
oxidative stress and treated with ETAC.
Results: Only the EHAC extract reduced cell viability by 30% after 72 h of treatment. Morphological analyses by
Immunofluorescence showed positive staining for glutamine synthetase, β-III tubulin, GFAP and IBA1 similar
to control cultures, indicating a better preservation of astrocytes, neurons and microglia, after excitotoxic
damage induced by glutamate in cerebellar cultures treated with the extracts. The ETAC extract also protected
mitochondria isolated from rat brains from oxidative stress, reducing the swelling, dissipation of the membrane
potential, ROS production and calcium influx.
Conclusion: Thus, this study suggests that the seed extracts from A. Cearensis exhibit neuroprotective potential
against oxidative stress and excitotoxicity induced by glutamate and can be considered a potential therapeutic
agent in the treatment of neurodegenerative diseases. | pt_BR |
