Effect of the PKC inhibitors staurosporine and Ro 31–8220 on the l-NA-induced increase in tone of rabbit aortic rings. Rabbit aortic rings were precontracted to ≈20% of the maximal phenylephrine-induced tone with PGF2α (open bars). Once a stable contraction had been achieved, l-NA was applied (hatched bars). Experiments were performed in the absence (A) and presence (B) of 100 nM staurosporine and 30 nM Ro 31–8220. Data are presented as the mean ± SEM of four separate experiments. ∗, P < 0.05.
