Citation abstract

Ganoderma lucidum extract (GLE) has neuro-therapeutic and anticonvulsant effects. This study aimed to evaluate the potential neuroprotective and antioxidant effects of ethanolic extract on pentylenetetrazol-induced brain damage in male Wistar rats and to analyze behavioral manifestations in vivo. Seizure latency, duration, and severity were measured in PTZ-treated rats according to the Racine scale; thus, oxidative stress markers, malondialdehyde (MDA), nitric oxide (NO), and catalase catalytic activity were measured by the 2-thiobarbituric acid, Griess reagent, and hydrogen peroxide methods, respectively. PTZ-injured rats showed both shorter seizure latency and longer seizure duration and intense seizure severity. The effects were enhanced by GLE in a dose-dependent manner. In addition, GLE decreased NO levels, increased catalase levels and decreased MDA levels in the hippocampus and the prefrontal cortex in rats treated with PTZ (75 mg/kg; i.p.). GLE conferred anticonvulsant and neuroprotective effects against PTZ-induced brain damage by repressing molecular processes involved in the production of oxidative stress markers.
