The effects of synthetic and natural phenol polymers on the release of plasminogen activator were examined on an isolated vascular preparation of the pig ear. Of the synthetic phenol polymers, the products of caffeine acid and 3,4-dihydroxyphenylacetic acid were found to raise the activity of plasminogen activator. As far as the natural polymers of phenol are concerned, only sodium humate was found to produce an action similar to that of the products of caffeinic acid and 3,4-dihydroxyphenylacetic acid.
