Objective: To investigate the mechanism of isinglass in the prevention and treatment of chronic atrophic gastritis (CAG) in rats. Method: Animal models of SD rats with CAG were made in accordance with the previous experience of combined administration of 60% ethanol, 20 mmol·L-1 sodium deoxycholate and 0.1% ammonia water. In prevention groups, sucralfate and isinglass were used as preventive therapy while CAG rat model was being made. In the reverse groups, sucralfate and isinglass were used to treat rats after establishment of CAG rat model. Finally all the rats were executed. Then the length of the proliferation zone of the gastric mucosa and serum epidermal growth factors(EGF) and growth hormones (GH) level were studied. Result: In isinglass prevention groups and high dose isinglass reverse group, the length of the proliferation zone of the gastric mucosa was very close to that in normal control group (P > 0.05), much better than model control group (P < 0.01). In low dose isinglass reverse group, it was lower than that in normal control group (P < 0.01), but much better than model control group (P < 0.01). In both prevention and reverse groups, serum EGF level was higher than that in normal (P < 0.01) and model control group(P < 0.05). Serum GH level was the same in every group (P > 0.05). Conclusion: The mechanism of isinglass in the prevention and treatment of CAG rats lies in revitalizing and proliferating gastric mucosal cells by stimulating endogenous EGF secretion.
