FIG. 1

Terminal ileum H and E sections from control pups [(A) magnification ×20] showing intact villi and close approximation of mucosa to underlying layers. Experimental pup intestine reveals grade 2 NEC, [(B) magnification ×20)] in the formula fed/hypoxia pups and grade 4, [(C) magnification ×20] in the formula fed/hypoxia/LPS pups. The long arrow highlights moderate submucosal separation in grade 2 NEC and the short arrow shows evidence of villous sloughing in grade 4 NEC.
