mRNA expression level of EGF and EGFR in mouse gastric. a–e In the same column, values with different letters are significantly different (P < 0.05) according to Duncan’s multiple-range test. Normal = normal mice; Negative control = mice treated with HCl/ethanol (10 mL/kg); Ranitidine = 50 mg/kg per day by gavage; HFY09 = mice treated with HCl/ethanol (15th day) and doses (L, H) of Lactobacillus plantarum HFY09 (10⁸, 10⁹ CFU/kg per day); LB = mice treated with HCl/ethanol (15th day) and Lactobacillus delbrueckii subsp. bulgaricus (10⁹ CFU/kg per day)
