In this study three forms of cyclic nucleotide phosphodiesterase (PDE) isolated from rabbit aorta were pharmacologically characterized, and the consequence of selective inhibition of calmodulin-stimulated PDE (CaM-PDE) and cGMP specific PDE (cG-PDE) was evaluated using PDE inhibitors. The cG-PDE (F1)

The objective this investigation was to determine the relative importance of type I, III, and IV phosphodiesterases in the regulation of cyclic adenosine monophosphate (cAMP) in the renal circulation. In the first experimental series, four groups of isolated rat kidneys
