Necrotizing enterocolitis (NEC) is a serious inflammatory intestinal disorder with a high mortality rate, which occurs most commonly in newborn infants., a common contaminant in infant formula, is associated with NEC. However, its role in NEC pathogenesis is unknown, and there are still no effective treatments for NEC. Currently, natural bioactive products have been investigated for their beneficial effects in preventing microbial infection. In this study, a neonatal mouse intestinal inflammation model was used to examine the protective effects of citral (a natural bioactive product) on-induced intestinal inflammation and damages. It was shown that citral reduced the number ofcells in ileal tissues, and mice treated with citral had a significantly higher body weight than-infected mice. Citral treatment also ameliorated serious ileal tissue damages, including epithelial sloughing, villous rupture, and enterocyte apoptosis.infection upregulated the messenger RNA transcription levels of several inflammation-associated genes, increased production of IL-6 and TNF-α, and activated the NF-κB and MAPK signaling pathways in ileal tissues. Citral treatment mitigated these inflammatory responses. The apoptotic index and activities of caspase 3, 8, and 9 increased in murine ileum afterinfection, but citral inhibited both enterocyte apoptosis and activations of these caspase. These findings suggest that citral has protective effects on-induced intestinal inflammation in newborn mice, and it may play a future role in the management ofassociated infections and diseases.
