Objective To establish a rat model of chronic atrophic gastritis and investigate the factors inducing gastric atrophy. Methods According to the repeated orthogonal design of L 8(2 7), 60% alcohol and 20 mmol/L sodium deoxycholate (served as factor A), 0.05%~0.1% ammonia water (factor B) and 0.05% indomethacin (factor C) were given, alone or in combination, to rats in three experiments for 3 months, 6 months and 9 months, respectively. Then the rats were sacrificed and pathologic changes of the gastric mucosa were studied by gross appearence and microscopy. Results Typical appearance of CAG, which could maintain over one month, were found in all rats treated with factor A,B,C alone or in combination for 6 or 9 months. Conclusion 60% alcohol, 20 mmol/L sodium deoxycholate, 0.05%~0.1% ammonia water and 0.05% indomethacin given to SD rats for 6 months could establish animal model of CAG with a 100% successful rate.
