superfused human isolated gastric mucosa released prostaglandin-like material and release was increased by stretching or clamping the tissue.2 the relative amounts of extracted biological activity were broadly as follows : gastric antral mucosa > colon muscle > gastric body mucosa approximately ileal mucosa > colon mucosa approximately gastric muscle approximately ileal muscle.3 prostaglandin e and f were tentatively identified by chromatography and sensitivity to inactivation by alkali.4 prostaglandin e apparently contributed most to the biological activity , possibly because the assay tissue is more sensitive to prostaglandin e than to f .
