Figure 4: Immunohistochemical staining of Ki-67 antibody in the representative tissue specimens. (a and b) control rats; (c and d) Helicobacter pylori infection and N-methyl-N-nitrosourea administration group; (e and f) Helicobacter pylori infection and N-methyl-N-nitrosourea administration supplemented with 60 mg/kg curcumin for 30 weeks. Images were obtained at ×20 (a, c, and e) and ×40 (b, d, and f). Diaminobenzidine stained immunoreactive cells (dark brown stain in their nuclei, arrows)
