Fig. 5.
Uninfected and H. pylori-infected male mice have elevated gastric pH. Acidity in gastric washes from male and female 129/Sv mice, either uninfected or infected with H. pylori for 2 weeks (n = 10), were measured by using a pH meter (mean ± standard error of the mean [SEM]). Gastric pH was significantly affected by gender (P = 0.002 [*]) but not by 2 weeks of H. pylori infection (P = 0.102) (two-way ANOVA).
