the proportions of prostaglandin f varied between specimens.5 the amount of extracted prostaglandin-like activity was increased by adding cofactors and arachidonic acid , and lessened by homogenization with acid-ethanol.6 the type and amount of activity generated from arachidonic acid by partly purified colonic mucosal prostaglandin synthetase depended on the substrate concentration.7 the possible relationships of prostaglandins to mucus secretion and other physiological and pathological gut functions are discussed .
