Curcumin Enhanced the Neomucosa Formation by Mediating the Antioxidation Mechanism in Rats

OBJECTIVES: The purpose of the study was to examine the possible effects of curcumin on the formation of neomucosa in parietal peritoneum which was applied as a patch for terminal ileal defect in rats. METHODS: Sixteen male Wistar Hannover rats were split into two groups. The control group was injected with saline and curcumin (2 mL/kg/day, by gavage) was given to the experimental group. In both groups, amounts of 8-hydroxy-2’-deoxyguanosine (8-OHdG) and malondialdehyde (MDA), the activities of glutathione peroxidase and superoxide dismutase were determined in serum. The development of neomucosa formation was examined morphologically. RESULTS: Serum antioxidant levels and glutathione peroxidase activity in rats given curcumin were significantly higher than those of the control group (p<0.05). The levels of oxidative markers (MDA and 8-OHdG) in rats given curcumin were significantly lower than those of the control group (p<0.05). In the histopathological examination, 62.5% of rats in the curcumin group showed formation of neomucosa while 37.5% of control rats showed neomucosa. CONCLUSION: The use of curcumin in rats with terminal ileal defect enhanced the formation of neomucosa by decreasing the oxidation level and increasing the antioxidation level. Curcumin may be used in the patients with short bowel syndrome to increase the absorption surface area.
