By implanting a Teflon chamber subcutaneously into a sheep a mild aseptic inflammatory lesion was produced from which wound fluid could be sampled daily. The prostaglandin content of this wound fluid was examined. Prostaglandin E2 activity was found in all samples, and a peak was apparent on the fourth or fifth day after producing the lesion. The amount of prostaglandin activity appeared to be unrelated to the total number of polymorphs in the fluid or to the volume of this exudate.
