Effects of inhibitors of nitric oxide signalling on relaxation to NAGly in mesenteric arteries. In endothelium-intact (A) and endothelium-denuded (B) vessels, relaxation was elicited by NAGly alone, or after treatment with l-NAME (300 µM) or l-NAME and apamin (50 nM) plus charybdotoxin (50 nM). (C) Relaxation was elicited by NAGly alone, or after treatment with ODQ (10 µM) in endothelium-intact vessels. n= 5–7. Values are shown as means, and vertical bars represent SEM.
