Abstract
The addition of oleoylanilide or linoleylanilide to human polymorphonuclear leukocytes induces a time‐and dose‐dependent generation of arachidonic acid. Half‐maximal effect is caused by a dose of 0.2 mg linoleylanilide/ml. Fatty acid anilides also produce a time‐ and dose‐dependent inhibition of the synthesis of triacylglycerol. Half‐maximal effect is caused by 1 μg linoleylanilide/ml. These results indicate that fatty acid anilides, which have been found in the illegal cooking oil which intoxicated thousands of Spaniards, alter lipid metabolism in human polymorphonuclear leukocytes.
