Effect of lisinopril and fosinopril in scopolamine-induced amnesic rats during the exploration trials in passive avoidance test. Comparison between control, scopolamine, lisinopril, and fosinopril during the exploration trials in passive avoidance test. Values are mean ± SE, ∗versus scopolamine (p < 0.05), ∗∗versus scopolamine (p < 0.001), aversus control (p < 0.05), and bversus control (p < 0.001).
