Objectives: Epilepsy is a neurological condition characterized by repeated seizures attributable to synchronous neuronal activity in the brain. The study evaluated the effect of acetone extract of Adansonia digitata stem bark (ASBE) on seizure score, cognition, depression, and neurodegeneration as well as the level of Gamma-Aminobutyrate acid (GABA) and glutamate in Pentylenetetrazol-kindled rats. Methods: Thirty-five rats were assigned into five groups (n = 7). Groups 1-2 received normal saline and 35 mg/kg PTZ every other day. Groups 3-4 received 125 mg/kg and 250 mg/kg ASBE orally while group 5 received 5 mg/kg diazepam daily for twenty-six days. Group 3-5 received PTZ every other day, 30 mins after ASBE and diazepam. Results: The results showed that Pentylenetetrazol (PTZ) induces seizure, reduces mobility time in force swim test and decreases the normal cell number in the brain. It also significantly decreases (p < 0.05) catalase, superoxide dismutase and reduced glutathione activities compared to the ASBE pre-treated rats. Pre-treatment with ASBE reportedly decreases seizure activities significantly (p < 0.05) and increases mobility time in the force swim test. ASBE also significantly elevate (p < 0.05) the normal cell number in the hippocampus, temporal lobe, and dentate gyrus. Conclusion: ASBE reduced seizure activity and prevented depression in PTZ-treated rats. It also prevented neurodegeneration by regulating glutamate and GABA levels in the brain as well as preventing lipid peroxidation.

The study investigates the role of Anogeissus leiocarpus methanol stem bark extract (ALSE) on seizure, oxidative stress and cognitive performance in pentylenetetrazole (PTZ)-induced epilepsy in rat model. Thirty Wistar rats were allocated into five groups (n = 6). Groups 1 and 2 received normal saline intra-peritoneal (i.p) every day and PTZ (i.p) at 35 mg/kg every other day respectively. Groups 3–5 were given ALSE orally at (250 mg/kg and 500 mg/kg) and Diazepam at 4 mg/kg (i.p) respectively. Groups 3–5 were given PTZ (i.p) at 35 mg/kg every other day for 30 days, 30 min after ALSE and Diazepam administration. The rats were observed for seizure activities and also evaluated for cognitive functions. The rats were euthanized thereafter and the brain histology and oxidative stress biomarkers were evaluated. PTZ induction resulted into increased seizure activities leading to the development of kindling, oxidative stress, cognitive impairment and histological aberration of the hippocampus. However, pretreatment with ALSE decreased seizure activities, reversed oxidative stress and cognitive impairment and preserved hippocampal histology relative to the PTZ alone treated rats. Conclusively, ALSE was found to increase seizure latency, prevented cognitive decline, and decreased seizure activities induced by PTZ-kindling in rats. Additionally, ALSE ameliorates PTZ-induced oxidative stress and histological aberrations of the hippocampus. Hence, this study proposed that ALSE might be a promising tool for ameliorating seizure in epilepsy.
