Fig. 7.
Effects of NOS inhibition on maximal vasorelaxation (A) and timeline of vasorelaxation during hypoxia (B). Vasorelaxation during hypoxia is not affected by NOS inhibition. l-NAME was added to the organ bath 50 min prior to the onset of hypoxia. Force is expressed as %change from PE-precontraction. N = 3–6/group.
