Caffeic acid phenethyl ester modifies the Th1/Th2 balance in ileal mucosa after γ-irradiation in the rat by modulating the cytokine pattern

Figure 6 Irradiation effect on intrinsic apoptotic factor expression modulation and caspase activity post-irradiation in rats. (■): CAPE-untreated (□): CAPE-treated. Apoptotic cells presence was confirmed by the terminal deoxynucleotidyltransferase (TdT)-mediated dUTP-biotin nick-end labeling (TUNEL) staining in ileum. (A): Control; (B): 6 h; (C): 7 d after γ-irradiation. (D): 6 h; (E): 7 d from irradiated CAPE-treated (x 20) (mean ± SEM, n = 6); ^bP < 0.01 vs control; ^dP < 0.01 vs untreated.
