Magnitude (Left) and duration (Right) of the increase in cavernosal pressure in response to intracavernosal injection of acetylcholine (ACh; Upper) or zaprinast (Lower) 1 day after administration of AdCMVβgal or AdCMVeNOS. Responses to acetylcholine and zaprinast 1 day after administration of vehicle were similar to those observed after administration of AdCMVβgal. n, number of experiments; ∗, response significantly different from AdCMVβgal (P < 0.05).
