Fig. 1From: Nitric Oxide-Dependent Penile Erection in Mice Lacking Neuronal Nitric Oxide Synthase Wild-type and nNOS − isolated corporal tissue tension effects following electrical field stimulation in response to the NOS inhibitor nitro- L -arginine methyl ester ( L -NAME) and the NO precursor L -arginine Equivalent contractile effects in the presence of L-NAME and relaxant effects in the presence of L-arginine were observed for both groups at the frequencies shown. The data are expressed as means ° SEM for six strips.Back to article page
