text_1: Chronic aerobic exercise alters endothelial function, improving vasodilating mechanisms mediated by NO.
text_2: To determine whether prostanoids and/or the nitric oxide synthase pathway were involved in the ET-induced changes in bradykinin-induced vasodilation, responses to bradykinin were examined in coronary resistance arteries from both ET and SED pigs in the presence of indomethacin and in the presence of nitro-monomethyl L-arginine (L-NMMA).
