Inhibition of nitric oxide synthase with L-NMMA (10 μmol/L) significantly reduces local dilation at low pulse durations (left panel) but not conducted (right panel) responses. This indicates that NO as an endothelial dilator is released at low ATP pulses but that NO is not involved in the conducted vasomotor responses. Data are presented as % maximum diameter to compensate for control diameter change induced after NOS inhibition. n = 5; * denotes p < 0.05 RANOVA between control and after L-NMMA.
