Normal: group that did not undergo ulcer induction; control 1: rats sacrificed on the 4th day after ulcer induction; control 2: rats sacrificed on the 4th day after ulcer induction; control 3: ulcerated rats treated with distilled water for 10 days; control 4: group of rats treated with sucralfate at a dose of 50 mg/kg. The values in the table represent the ; ^a, ^ab, and ^abc: statistically significant difference from control 2; , , and : statistically significant difference from control 3; ⁺, ⁺⁺, and ⁺⁺⁺: statistically significant difference from normal.
