FIGURE 5.

Immunohistochemical staining of endothelial nitric oxide synthase (eNOS) in gastric mucosal tissues. Representative gastric mucosal sections from (A) normal control animals, (B) ulcerative animals treated with indomethacin alone (60 mg/kg), (C,D) ulcerative rats treated with indomethacin + PGG at two doses: 100 and 200 mg/kg, respectively, and (E) ulcerative animals treated with indomethacin + famotidine-treated group (10 mg/kg). Brown and blue indicate positive and negative staining of eNOS, respectively. Avidine biotin peroxidase stained with Hx counter stain x200. Data are expressed as mean ± S.E, n = 10. *^,@significantly different from corresponding control group of rats and indomethacin group, respectively, at p < 0.05 by one-way ANOVA was used for statistical analysis followed by Tukey’s post hoc test.
