G. Anderson A1 S. D. Markowitz A1 D. D. Bonnycastle YR 1962 UL http://jpet.aspetjournals.org/content/136/2/179.abstract AB The relationship between the rise in brain 5-hydroxytryptamine and anticonvulsant action of diphenylhydantoin has been investigated, and some correlation between the time courses of each was noted. However, comparison of the relative effects of diphenylhydantoin, phenylisopropyl hydrazine and 5-hydroxytryptophan on the maximal extensor reflex in response to electroshock and rise in brain 5-hydroxytryptamine showed a complete lack of correlation.
