Colon epithelial cells assessed via atransmission electron microscope. HIBD could result in edematous changes in the matrix, cristae in the mitochondria, the sparse distributed swelled microvilli, the vague epithelial cell organelles, remarkable decreased junctions and the loosened interstitial tissue (e-h) compared with sham group (ad). Melatonin treatment could reduce the severity of pathology after injury (i-l). Red solid arrows represent tight junctions, red hollow arrows represent intestinal epithelium microvilli, and ▲ represents mitochondria
