Reduction of duration and severity of megimide seizures in rats on a folic acid deficient diet.

Folic acid deficient diet reduces the duration and severity of intravenous megimide seizures in the rat after 6 months of diet. Plasma and serum folate levels are strongly reduced after that period. The difference between Lactobacillus casei and Streptococcus faecalis activity in brain show a slight, but not significant, decrease after 12 months of diet.
