Representative micrographs (× 400) stained by anti-bromodeoxyuridine (anti-BrdU) immunohistochemical method (A), and quantitation of the number of total (B) and BrdU-labeled (C) cells in the proliferation zone from the duodenal mucosa of the rats. Data are mean ± SD (n = 8). The nuclei of BrdU-labeled cells were stained in brown. The number of total and BrdU-labeled cells was obtained from three individual crypts for each rat. Values not sharing the same letter differ significantly (P < 0.05) within the same day by Fisher’s least significant difference test.
