Superoxide production within vascular walls of rabbit mesenteric resistance arteries. (A) Superoxide production was estimated from the fluorescence intensity of the superoxide-sensitive dye dihydroethidium. (B) Effects of in vitro applications of Mn-TBAP, GF109203X and L-arginine+5-MTHF on superoxide production in NTG-treated rabbits. For both (A) and (B), similar observations were made in other sections obtained from four preparations from four other animals.
