“Immunoblotting assay results revealed that silymarin reduced 4-aminopyridine-induced phosphorylation of ERK1/2.”
“In rat cortical synaptosomes, silymarin reduced glutamate release and calcium elevation evoked by the K+ channel blocker 4-aminopyridine but did not affect glutamate release caused by the Na+ channel activator veratridine or the synaptosomal membrane potential.”
