5-FU treatment induced decrease in leukocytes number in blood and in PCNA positive cell in small intestine of CV and GF groups. Leukocytes number in blood was reduced after 5-FU treatment of CV, GF, and AB groups when compared to respective control (a). The number of PCNA-positive epithelial cells was equally decreased in both CV and GF mice on 3rd day after 5 FU injection (b). These effects were not different between the several 5-FU-treated groups. These data were displayed in histological representation (10X) (c). NC: negative control staining. The data represent the mean ± SEM of 5–6 animals per group. *p < 0.05 vs respective control.
