we have investigated the effects of norepinephrine ( ne ) and acetylcholine ( ach ) on prostaglandin ( pge2 and 6 keto-pgf1 alpha ) production by rabbit iris , measured by radioimmunoassay ( ria ) , and the type of phospholipase activated by ne in irides in which phosphatidylinositol ( pi ) was doubly prelabeled with [ 3h ] myo-inositol and [ 1-14c ] arachidonic acid ( 14c-aa ) , quantitated by radiometric and chromatographic methods .
