Measurement of the lesion area, inhibition percentage, alcian blue binding capacity and pH.

The experiment consisted of the negative control group (Group 1), the complex control group (Group 2), the lesion control group (Group 3), the reference group pre-treated with 20 of omeprazole (Group 4) and the experimental groups (Groups 5–8) which received 1.091×10−5, 2.181×10−5, 4.362×10−5 and 8.724×10−5 M/kg of the zinc (II) complex as a pre-treatment. All values are expressed as mean ± standard error mean. Mean difference is significant at the p<0.05 level (one-way between groups ANOVA with post-hoc analysis). *significant when compared to the ulcer control group (Group 3). #significant when compared to the reference control group (Group 4).
