(A) Schematic representation of the NO–cGMP relaxant pathway. Bold arrows indicate targets of the different drugs we used. (B) Wall tension recordings of the effect of ACh in PGF_2α-precontracted rat intrapulmonary arteries incubated for 24 hr in the absence (black trace) or presence (gray trace) of SRM1648(200 μg/mL). Oscillations during contraction are not a characteristic feature of SRM1648-exposed arteries, because we also observed them in unexposed arteries.
