FIG. 3.

Levels of IL-12 protein as determined by ELISA in 100-μg portions of total protein extracts obtained from freshly gastric biopsies from H. pylori-infected patients (n = 10; median inflammation score, 2.5 ± 0.26) and from uninfected patients with NSAID-related gastritis (n = 6; median inflammation score, 1.5 ± 0.22) (w gastritis) and without gastritis (n = 4; inflammation score, 0) (w/o gastritis). Statistical significance was assessed by ANOVA and Tukey's multiple-comparison tests. ns, not significant.
