title: Effect of dipyridamole on the formation of 6-oxo-prostaglandin F1 alpha by the rat isolated aorta and ram seminal vesicle microsomes.
abstract: 1 Dipyridamole (1 and 10 muM) enhanced the production of 6-oxo-prostaglandin F1 alpha by rat aortic tissue. 2 Dipyridamole (5 to 40 muM) did not influence the PGI2-synthetase activity in ram seminal vesicle microsomes whereas, in concentrations ranging from 100 to 200 muM, it reduced the metabolism of exogenously added arachidonic acid. The latter effect may be due to an inhibition of the cyclooxygenase.
