[Release of prostaglandins and their precursors by bradykinin].

Bradykinin induces a release of unsaturated fatty acids and of prostaglandins from the perfused rat lung. This release is inhibited by chloroquine, a phospholipase A inhibitor. Histamine has no stimulating effect on fatty acids production. It is suggested that prostaglandins release induced by bradykinin might depend on a phospholipase activation.
