Abstract

Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.Objectives: This study was designed to evaluate effects of hyperbaric oxygen (HBO) plus 3-aminobenzamide (3-AB) cotreatment on tissue oxidative stress parameters (TOSp), tissue histopathology scores (THSc), and bacterial translocations (Bact-Trans) in an experimental model of severe acute pancreatitis (AP). Methods: Seventy-five Sprague-Dawley rats were randomized into 5 groups. Group 1 received sham. Severe AP was induced by intraductal taurocholate infusion and then group 2 received saline, group 3 received 3-AB, group 4 received 3-AB plus HBO, and group 5 received HBO. 3-Aminobenzamide (10 mg/kg per day, once daily, intraperitoneal) and saline (1 mL/kg) were started right after the induction, whereas HBO (2,8 atm pressure, BID, 90 minutes each) was started at the sixth hour. The rats were euthanized at the 54th hour, and TOSp, THSc, and Bact-Trans were studied.Results: In treatment groups 3 and 5, Bact-Trans (P < 0.05, P < 0.05), TOSp (P < 0.05, P < 0.05), and THSc (P < 0.001, P < 0.001) were significantly lower than controls. In addition to these findings, group 4 (cotreatment) showed the most significant effect on Bact-Trans and THSc (P < 0.001, P < 0.001) and also better in TOSp (P < 0.02).Conclusions: Poly(ADP-ribose) polymerase inhibition by 3-AB and HBO treatment alone was effective in the course of severe AP, and favorable with cotreatment because of the improved cascades of inflammatory process by different aspects.
