    AbstractEpilepsy is a widespread and mainly severe neurological condition portrayed by recurring spontaneous seizures caused by the brain's abnormal electrical activity. According to new research, inflammation may be both a result and the cause of epileptic seizures. The highest zinc levels in the brain have been found in the hippocampus which is one of the most studied regions of the brain regarding epilepsy. Zinc may have an anti-inflammatory potential as zinc co-factors affect numerous biochemical and physiological reactions. In this study, we evaluated the effects of intraperitoneal zinc administration on seizure activity in murine PTZ model. Rats received either intraperitoneal (IP) zinc sulfate at two different dosages (50-100 mg/kg) or a placebo followed by pentylenetetrazole (IP), a strong seizure-inducing drug. The spike percentages were considerably lower in the PTZ (35 mg/kg) and 50 or 100 mg/kg zinc-treated groups (A3 and A4) than in the PTZ (35 mg/kg) and saline-treated group (A2; p may be used as an adjuvant therapy in combination with other antiepileptic drugs in the future (Tab. 3, Fig. 1, Ref. 27) Keywords: anti-seizure effect of zinc, epilepsy, abnormal electrical activity, antiepileptic drugs, rat model.
