Vasodilator responses of isolated and pressurized porcine retinal arterioles to bradykinin and resveratrol. (A) Vasodilation to bradykinin (1 nM) was examined in the absence (Denudation, n = 5) or presence (n = 5) of endothelium, or before and after administration of L-NAME (n = 5), SU1498 (n = 4), wortmannin (n = 5), MG132 (n = 5), PD150606 (n = 5), or EX527 (n = 8). (B) Vasodilation to resveratrol (30 μM) was examined before and after administration of wortmannin (n = 5), MG132 (n = 5), or EX527 (n = 5). *P < 0.05 versus Control.
