FIGURE 2. Effect of nitric oxide synthase inhibition with subcutaneous l-NAME (10 mg/kg) and the effect of l-NAME combined with intraperitoneal l-arginine (l-Arg; 300 mg/kg) or d-arginine (d-Arg; 300 mg/kg) on bombesin (100 μg/kg)-induced gastric hyperemia. Data are presented as percent change from baseline blood flow determinations and represent the mean ± SEM; n ≥ 5/group. *P < 0.05 versus saline counterpart. +P < 0.05 versus saline/bombesin. #P < 0.05 versus l-NAME/bombesin.
