The effects of a 4%-protein diet in adult rats with respect to the morphometric aspects of the myenteric plexus in the ileum were assessed. Twenty animals were randomly divided into two groups: Control Group (n = 10), which received 26%-protein chow, and Experimental Group (n = 10), which received 4%-protein chow for 90 days. Neurons in the myenteric plexus in the ileum in whole mount were evidenced through Giemsa and NADH-diaphorase techniques. The overall neuronal population as well as the subpopulation positive for NADH diaphorase presented atrophy, with a reduction of the perikaryon, nucleus and cytoplasm.
