Effects of hydrotalcite combined with esomeprazole on gastric ulcer healing quality: A clinical observation study

Figure 3 Gastric mucosal fibrosis was evaluated by Masson’s trichrome staining in a 200 × field. Blue-stained signals represent fibrosis. A: Combination therapy before and after treatment; B: Monotherapy before and after treatment; C: Healthy control group. The area of collagen fiber deposition in the combination therapy group was significantly larger than that in the monotherapy group after treatment, and was similar to that in normal mucosal tissue.
