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

Figure 4 Effects of chronic Helicobacter pylori infection on the expression of insulin-like growth factor-1 and insulin in the pancreas of Mongolian gerbils. A: Immunohistochemistry scores of insulin-like growth factor-1 (IGF-1) and insulin were determined in the control and Helicobacter pylori (H. pylori) groups at 6 and 12 mo (n = 8-10). Data are expressed as the mean ± SEM. ^aP < 0.05 between H. pylori infected mice at 6 mo and their controls concerning the expression of IGF-1; B: Representative immunohistochemical staining of IGF-1 and insulin expression in the pancreas of Mongolian gerbils at 6 mo after H. pylori infection (magnification × 400).
