Özet

Background/Purpose: The role of cytokines in the pathogenesis of hemodynamic instability or tissue destruction in patients with necrotizing enterocolitis (NEC) remains undefined. The aim of this study was to determine the effects of recombinant human interleukin-102 (rhIL-10) on intestines of hypoxia-induced necrotizing enterocolitis in immature rats. Methods: The study was performed on 1-day-old Sprague Dawley rat pups. Group 1 (n = 8) served as nonhypoxic controls. Group 2 (untreated, n 11) rats were subjected to hypoxia-reoxygenation (H/O) and then were returned to their mothers. Group 3 (rhIL-10 treated, n = 10) rats were subjected to H/O, were returned to their mothers, and were treated with rhIL-10 (75 mug/kg subcutaneously) for the next 3 days. All animals were killed on day 4, and intestine specimens were obtained to determine the tissue level of malon-dialdehyde (MDA) and histologic changes. Results: The microscopic lesions in the untreated rats were virtually the same as those seen in neonatal NEC, with destruction of villi and crypts, and in some cases extension to the muscularis. In contrast, in the rats treated with rhIL-10, lesions were limited essentially to the very tips of the villi. Intestinal injury score was significantly less in the rhIL-10-treated rats than in the untreated rats (P < .05). In the rhIL-10-treated group, Malondialdehyde (MDA) levels were not significant in comparison to the control group. In the untreated group, MDA levels were significantly increased when compared with the control and the rhIL-10-treated groups (P < .001 and P < .05, respectively). Conclusion: RhIL-10 has a protective effect on intestinal injury in NEC in an experimental model. Copyright 2002, Elsevier Science (USA). All rights reserved.
