The aim of the present study was to examine the effect of subchronic co-administration of folic acid (F) and L-arginine (A) on behavioural and electroencephalographic (EEG) characteristics of DL homocysteine thiolactone (H) induced seizures in adult rats. The activity of membrane ATPases in different brain regions were also investigated. Rats were treated with F, A, or vehicle for 15 days (regimen: F 5 mg/kg + A 500 mg/kg (F5A500); F 10 mg/kg + A 300 mg/kg (F10A300)). Seizures were elicited by convulsive dose of H (H, F5A500H, F10A300H) Subchronic supplementation with F and A did not affect seizure incidence, number of seizure episodes, and severity in F5A500H and F10A300H groups vs. H group. However, a tendency to increase latency and decrease the number of seizure episodes was noticed in the F10A300H group. EEG mean spectral power densities during ictal periods were significantly lower in F10A300H vs. H group. The activity of Na+/K+-ATPase and Mg2+-ATPase was significantly increased ...in almost all examined structures in rats treated with F and A. We can conclude that subchronic supplementation with folic acid and L-arginine has an antiepileptic effect in DL homocysteine thiolactone induced epilepsy.
