Nitrogen-Free Plasmalogen Observed in Infarcted Myocardium of the Dog

Abstract

Heart tissue from dogs in which myocardial infarction was induced experimentally was analyzed histochemically and chromatographically for plasmalogens. A new, nitrogen-free plasmalogen was observed that was confined to the infarcted area; marked histochemical alterations in the pattern of distribution of the plasmalogens occurred. The new plasmalogen is believed to be a polymer of phosphatidic acid plasmalogen.
