Ischemia-reperfusion injury is a clinical condition that poses life-threatening risks and can be caused by diseases or operations such as trauma, shock, and gastric dilatation volvulus. The objective of this study was to examine the effect of oxytocin on intestinal damage in rats induced by experimental ischemia-reperfusion injury. Three groups of Wistar albino rats were established: a control group (CTR, n=6), an intestinal ischemia-reperfusion group (I-IR, n=6), and an intestinal ischemia-reperfusion with oxytocin group (I-IR+Oxt, n=6). The I-IR+Oxt group received an intraperitoneal injection of 1 mg/kg oxytocin 30 minutes before anesthesia. In the I-IR and I-IR+Oxt groups, the superior mesenteric artery was ligated for 1 hour to induce ischemia-reperfusion injury, followed by one hour of reperfusion by opening the ligatures. At the end of the reperfusion period, the rats were euthanized, and blood and intestinal tissue samples were collected. From the blood samples, ALT, ALP, AST, LDH, BUN, creatinine, IL-1β, and TNF-α concentrations were evaluated. Tissue samples were analyzed for IL-1β, TNF-α, and MDA activity. Serum and tissue IL-1β and TNF-α concentrations were higher in both the I-IR and I-IR+Oxt groups compared to the CTR group. However, these levels were found to be lower in the I-IR+Oxt group compared to the I-IR group. The histopathological analysis showed that the I-IR+Oxt group had better epithelial regeneration and less inflammatory cell infiltration compared to the I-I/R group. In conclusion, oxytocin inhibited the release of IL-1β and TNF-α and the harmful effect of I/R on intestinal cells.
