Acetoxycycloheximide enhances audiogenic seizures in DBA-2J mice.

Inborn errors of metabolism often cause epilepsy, as with certain strains of mice. Aggravating the metabolic defect with a protein synthesis inhibitor increases the symptoms. Mature animals that have "outgrown" their genetic susceptibility to audiogenic seizures are made susceptible again by acetoxycycloheximide. After a single small dose the incidence and severity of audiogenic seizures increases at 16 hours, reaches a maximum of 40 hours, and then declines gradually.
