Effects of PTX on cellular proliferation of colon epithelium in the experimental mice. (A) Assessment of the normal crypts in the colon of AOM-treated db/db mice using antibody for proliferating cell nuclear antigen (PCNA). Sections of the colon from each group were stained immunohistochemically with anti-PCNA antibody, as described in the Materials and Methods section. Representative photomicrographs from each group are shown. Scale bars, 200 µm; (B) Evaluation of PCNA labeling index in the normal crypts in the colon of the experimental mice. Each column represents the mean ± SD (n = 6 for each group). * p < 0.05 vs. PTX-untreated control group.
