Abstract
Background and Purpose: Ethanol is known as anticonvulsant and proconvulsant but sometimes has no effect on seizure. There is no report about the role of ethanol on the anticonvulsant effect of Valproic acid (VPA). In this study، we explore the effect of ethanol on the anticonvulsant effect of VPA.
Methods and Materials: In this experimental study، eight groups of mice (25-30 gr) were injected pentylenetetrazol (PTZ) (37 mg/kg; ip) every other day (3 times a week). Groups receiving ethanol (0.5 and 1 g/kg; 7 and 21 continuous days; everyday; ip)، PTZ was injected 30 minutes after ethanol. In Valproic acid+ethanol، Valproic acid (100 mg/kg) was injected 5 minutes before ethanol (1 g/kg). Immediately after PTZ injection، seizure stages were recorded for 20 min. Seizure stage-4 duration (S4D)، seizure stage-4 latency (S4L) and seizure stage 1 latency (S1L) were recorded from each mouse after PTZ injection، and data were compared with control groups. The basis of all decisions was a significant level of P
