(A) Tracings illustrating the effects of L-NAME on field stimulation-induced relaxant responses of the pig anococcygeus and retractor penis muscles. (B) Mean data for the effects of L-NAME (100 μM), L-NAME plus L-arginine (1 mM) and tetrodotoxin (1 μM) on field stimulation-induced relaxations of the pig anococcygeus and retractor penis muscles muscle. Columns represent means and I-bars indicate the s.e.mean of 4–5 experiments. *Indicates a significant difference (P<0.05, Student's t-test) from the corresponding control group.
