Effect of the NOS inhibitor L-NAME on EFS-evoked hyperpolarization in the longitudinal smooth muscle of the chicken mesenteric artery. (A) Typical recordings of EFS-evoked responses in the absence (control) or presence of L-NAME (100 µM) are shown. (B) Peak amplitudes of EFS-evoked hyperpolarization are summarized as means ± SEM (n= 5). *Significantly different from control values (P < 0.05). EFS, electrical field stimulation; L-NAME, Nω-nitro-L-arginine methyl ester; NOS, nitric oxide synthase.
