Potential effect of chronic Helicobacter pylori infection on glucose metabolism of Mongolian gerbils

Figure 5 Effects of chronic Helicobacter pylori infection on the apoptosis of islet β-cells in Mongolian gerbils. A: Apoptotic rate of islet β-cells was detected by TUNEL assay in the control and Helicobacter pylori (H. pylori) groups at 6 and 12 mo. Data are expressed as the means ± SEM (n = 8-10 mice/group). P > 0.05 was observed between H. pylori infected mice and their controls; B: Representative images of islet β-cells in the pancreas of Mongolian gerbils at 6 mo after H. pylori infection by TUNEL staining (magnification × 400).
