Adhesion ability of H. pylori increased under the treatment of higher glucose concentration. Strain J99 and 43504 growth in different level of glucose (100, 150, 200 mg/dL) was added to AGS cells with the pretreatment of the same glucose concentration (A, B) or the pretreatment of contrary concentration (200, 150, 100 mg/dL) (C, D). Relative adhesion ratio indicates that the adhesion of H. pylori in 100 mg/dL of glucose serve as the reference, and the bacterial adhesion value in 150 and 200 mg/dL of glucose was divided by the value of reference. *indicated a significant difference between the treatment of different glucose concentrations (paired t test, p < 0.05).
