Histopathological comparison of topical therapy modalities for acute radiation proctitis in an experimental rat model

Figure 1 Sum of the histopathologic scores regard to the euthanasia days. 1: control group; 2: mesalazine group; 3: formalin group; 4: betamethasone group; 5: misoprostol group. The differences in the mean scores of all groups, but the formalin group on the 10^th and 15^th d and betamethasone group on the 10^th and 15^th d were statistically significant.
