Chronic gastritis rat model and role of inducing factors

Figure 1 Severe infiltration of inflammatory cells, decreased thickness of lamina propria and lessened pyloric glands in gastric antrum of rats with gastritis induced by factor A. The results induced by factors A + B + C, A + C, A + B were similar. HE stain × 100. Factor A: Combined intragastric treatments of 600 mL/L alcohol, 20 mmol/L sodium deoxycholate and 0.5 g/L ammonia;Factor B: Treatment of forage containing low levels of vitamins; Factor C: Treatment of indomethacin.

Figure 2 Severe infiltration of inflammatory cells, decreased parietal cells in oxyntic glands in gastric body of rats with gastri-tis induced by factor A with no changes in thickness of lamina propria. The results induced by factors A + B + C, A + C, A + B were similar. HE stain × 100. Factor A: Combined intragastric treat-ments of 600 mL/L alcohol, 20 mmol/L sodium deoxycholate and 0.5 g/L ammonia; Factor B: Treatment of forage contain-ing low levels of vitamins; Factor C: Treatment of indomethacin.
