Özet

Objective: The aim of this study is to investigate the efficacy of tadalafil against pentoxifylline in rat model of ischemic colitis (IC). Material-Methods: Thirty-twoWistar albino rats were subjected to laparotomy and left colon devascularization to create an IC model and then randomly placed into four groups. Group-1 (sham group) was administered 0.9% NaCl following laparotomy, group 2 (control group) was administered 0.9% NaCl following induced IC, group 3 was given pentoxifylline (n = 8), and group 4 was given tadalafil. On the third day; macroscopic findings, Gomella's ischemic area and Wallace scoring, histopathological analysis, and Chiu scoring were performed, and malondialdehyde (MDA) measurement in ischemic colon tissue was carried out through chemical analysis. Results: Significant differences were observed in acidic fluid, bowel dilatation, and serosal change (p < .05). The ischemic area measured 63.3 mm(2) in the control group, 2.8 mm(2) in the pentoxifylline group (p = .0001), and 2.4 mm(2) (p = .0001) in the tadalafil group. A significant difference was seen between the sham group and the control and pentoxifylline groups (p < .01), in terms of Wallace score and Chiu classification. Similarly, a significant difference was determined between the control group and pentoxifylline and tadalafil groups (p <.01), but no significant difference was established between the pentoxifylline group and tadalafil group (p = .33). MDA measurement was found on an average to be 63.7 in the control group, 22.7 in group 3 and 22.8 in group 4 (p = 001). Conclusion: Although tadalafil is superior to pentoxifylline, both drugs are considered to have positive effects.
