Photomicrograph in CA1 of the hippocampus a Control group showing a normal structure of CA1. b Acrolein-treated group showing increased apoptotic neurones with dystrophic changes in the form of shrunken hyperchromatic, chromatolysis (arrows). c Quercetin nanoparticle-treated group showing normal neuronal cells (arrows). d Ameliorative group showing a decrease in ischaemic neuronal injury of neuronal cells (arrowheads indicate atrophic cells). e Protective group showing a marked decrease in neuronal injury of the neuronal cells (arrowheads). f Recovery group showing a minor decrease in ischaemic neuronal injury of neuronal cells (arrowheads).
