Objective: To explore the relationship between epidermal growth factor(EGF),gastrin,somatostatin and inflammatory cytokines and chronic gastritis(CG) in rats.Methods: Rats model of chronic gastritis were established,EGF,gastrin,somatostatin,IL-2,IL-4 and TNF-α from blood of CG model rats were measured by ELISA.Results: EGF,gastrin,IL-2 and TNF-α in model group were higher than those in normal control group.IL-4 was lower than those in normal control group,and there was no difference in somatostatin of normal model groups (P~〉 0.05 )...
