The underlying etiology of the toxic oil syndrome may be related to any of several toxic contaminants. The hypothesis is made that two or more toxic compounds may act synergistically to cause vascular damage in the toxic oil syndrome. To support this hypothesis, previous studies are reviewed concerning the remarkable synergistic toxic action of allylamine and beta-aminopropionitrile on the media of blood vessels. Although these toxins are not directly related to the toxic oil syndrome, this previous experimental work emphasizes the possibility that unexplored synergistic actions may be important. Furthermore, the hypothesis that contaminating fatty acid anilides in toxic oil undergo alterations during cooking is supported by high pressure liquid chromatographic analysis.
The theoretic metabolism of fatty acid anilides is discussed. Recent data concerning the toxic actions of the anilides of oleic and linoleic acid are given. These data suggest that these anilides induce immunologic alterations that may be similar to those seen in the toxic oil syndrome. In addition, the heated anilides appear to have increased toxicity, supporting the concept that the use of toxic oil in cooking may increase its toxicity.
