Oxidative and nitrosative stress enzymes in relation to nitrotyrosine in Helicobacter pylori-infected humans

Figure 1 Scatter-plot demonstrating the result of Western blot inducible nitric oxide synthase, myeloperoxidase and nicotinamide adenine dinucleotide phosphate-oxidase protein expression in biopsies from the anrum of the Helicobacter pylori neg (n = 13) and Helicobacter pylori pos (n = 8) groups. A: Inducible nitric oxide synthase (iNOS), ^bP < 0.01; B: Myeloperoxidase (MPO), ^aP < 0.05; C: Nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase subunit p47-phox in biopsies from the antrum of the H. pylori neg. (n = 13) and H. pylori pos. (n = 8) groups, ^bP < 0.01, OD: Optical density.
