Ações neuroprotetoras da vitamina C no corpo estriado de ratos após convulsões induzidas pela pilocarpina

Abstract: ResumoContexto: As convulsões podem produzir danos neuronais em diversas áreas e, especialmente, nas estruturas límbicas. Objetivos: O objetivo do presente trabalho foi estudar os efeitos neuroprotetores da vitamina C nas alterações histopatológicas observadas no corpo estriado de ratos convulsivos. Material e métodos: Foram utilizados ratos Wistar adultos. Os animais foram divididos em quatro grupos. O primeiro grupo foi tratado com salina 0,9% (grupo controle) e o segundo, com pilocarpina (400 mg/kg, grupo P… Show more

“…PTZ is a non-competitive antagonist of GABA A receptors, which act closing Cl À channels, thereby reducing the inhibitory neurotransmission mediated by GABA (Qu et al, 2005;Silva et al, 1998). The blockade of the onset of seizures induced by pilocarpine may be achieved by anti-cholinergic drugs, suggesting that activation of the muscarinic cholinergic receptor contributes to the initiation of seizures (Freitas and Tomé, 2010). Strychnine acts as a competitive antagonist of glycine, which reduces the inhibitory effects on the central nervous system (Kaputlu and Uzbay, 1997).…”
