Endogenous anandamide in monocytes from cirrhotic and control rats. A representative LC/MS analysis of samples extracted from the monocyte fraction of 20 ml pooled blood of sham-operated (a) and cirrhotic (b) rats. Two selected ions were monitored simultaneously: m/z 356.2 for d₈-anandamide ions as internal standard (upper panels) and m/z 348.2 for anandamide ions (bottom panels). Numbers at the peaks indicate the Liquid chromatography (LC) retention time of the compounds in minutes.
