Data are expressed as the number of rats exhibiting each score of gastric erosion and PMN infiltration (n = 6).
1
The gastric erosion score: Score 0: No erosion; Score 1: Erosion 1/3 of epithelium depth; Score 2: Erosion 2/3 of epithelium depth, or develop ulcer.

The gastric infiltration level was estimated and scored by the pathologist following the update Sydney System[29]. PMN infiltration score: Score 0: No infiltration; Score 1: PMN infiltrate 1/3 of epithelium; Score 2: PMN infiltrate 2/3 of epithelium; Score 3: PMN infiltrate all depth of epithelium represented normal, mild, and marked mucosal injury respectively.
