Oleanolic acid suppresses pentylenetetrazole-induced seizure in vivo

open access: yesInternational Journal of Environmental Health Research, 2023
The aim of this study was to investigate the protective effects of triterpene oleanolic acid on the brain tissue of mice with pentylenetetrazole (PTZ)-induced epileptic seizures. Male Swiss albino mice were randomly separated into five groups as the PTZ, control, and oleanolic acid (10, 30, and 100 mg/kg) groups.
