Abstract Pregnant mice are more susceptible to flurothyl-induced seizures than are non-pregnant controls. The possibility that the well-known increase in beta-endorphin concentration which accompanies pregnancy was involved in this effect was examined by testing whether naloxone administration could block the increased seizure susceptibility. Pregnant female, control female and male C3H mice were treated with 5-50 mg/kg naloxone 5 min before flurothyl seizure testing. Naloxone markedly increased clonic seizure susceptibility in all three groups at a dose of 50 mg/kg, but had little effect at lower doses. In contrast, naloxone had differential effects on myoclonic seizures in pregnant and control female mice, being anticonvulsant in the controls, but proconvulsant in the pregnant mice. A role for endogenous opiates is unlikely in mediating clonic seizures in pregnant mice, but may be involved in myoclonic seizures.
