these studies indicate that a ) unlike the mammalian preparations prostacyclin synthetase does not appear to be a major enzymatic activity of the pigeon aorta , rather , b ) pgh-pge isomerase is the major endoperoxide metabolizing activity in the pigeon aorta and thus , c ) a deficiency of prostacyclin production is not involved in the geneis of atherosclerosis in the pigeon .
