Abstract
BACKGROUND: The purpose of this study is to investigate the potential protective effect of the ukrain on ischemia-reperfusion (IR) injury in rat intestine, which has not previously been studied. METHODS: Thirty-one male Sprague-Dawley rats were randomly assigned to four groups, each consisting of eight rats as follows: (1) a sham group (S) (laparotomy, but no IR injury); (2) ukrain group (U) (no IR, and ukrain was administered intraperitoneally 1 h before laparotomy); (3) intestinal ischemia-reperfusion (II/R) group (30-min occlusion of the superior mesenteric artery then 2-h reperfusion); and (4) ukrain + II/R group (U + II/R) (30-min occlusion of the superior mesenteric artery then 2-h reperfusion; ukrain was administered intraperitoneally 1 h before IR). RESULTS: Serum total oxidant status (TOS) and total antioxidant status (TAS) were measured using Erel method. Oxidative stress index was calculated using the TOS/TAS ratio. TAS levels increased and TOS serum levels were also significantly decreased in the ukrain + IR group compared with the IR group (P = 0.000 and P = 0.015). CONCLUSIONS: In this study, we demonstrated for the first time in literature that ukrain helps to prevent intestinal tissue breakdown against II/R injury and that this effect can be achieved by antioxidant activities.
