Response of nitric oxide pathway to l-arginine infusion at the altitude of 4,350 m

It was hypothesized that hypoxia may inhibit nitric oxide (NO) production by reducing the availability of endothelial NO synthase (NOS III) substrate. To evaluate the effect of L-arginine on the NO release in high altitude, 11 subjects were infused with L-arginine (0.5 g x kg(-1)) during 30 min in n...
