Arachidonic acid and arachidonoyl-diglycerols increase in rat cerebrum during bicuculline-induced status epilepticus

N G Bazan et al. Neurochem Res. 1982 Jul.

Abstract

Bicuculline-induced status epilepticus was found to be associated with increased amounts of free fatty acids and diacylglycerols in the rat cerebrum. The predominant fatty acid in both lipid pools was arachidonic acid. The accumulation of arachidonoyl-diglycerols decreased at the time of and during behavioral seizures induced by bicuculline, while the amount of free arachidonic acid appeared to increase. We propose a metabolic relationship between these lipids to explain the described changes. The similarities between the composition of the lipid pools and the fatty acid composition of phosphatidylinositol support the hypothesis that these changes may be a result of a convulsion-activated degradation of this phospholipid from excitable membranes.
