The effects of L-nitroarginine (L-NNA), an inhibitor of nitric oxide (NO) synthesis, on non-adrenergic, non-cholinergic inhibitory transmission in the circular smooth muscle of the rat gastric fundus were studied. The relaxation in response to nerve stimulation in the presence of guanethidine and atropine was depressed by the application of L-NNA (10(-4) M), and the depression was reversed by the addition of L-arginine (10(-4) M). The time course of the relaxation was altered from a monophasic to biphasic one, both of which were depressed. Stimulation of non-adrenergic, non-cholinergic nerves initiated inhibitory junctional potentials (i.j.p.). In addition, slow after-hyperpolarization was observed when stimuli were applied repeatedly at frequencies higher than 0.5 Hz. L-NNA reduced the i.j.p. partially and abolished the after-hyperpolarization, indicating the partial involvement of NO in non-adrenergic, non-cholinergic inhibitory transmission. The effects of L-NNA on the nerve-mediated relaxation are thought to be due to changes in the i.j.p. and slow after-hyperpolarization.
