Neuron counts and percentages of normal and degenerate neurons in the submucosal plexus and myenteric plexus of post perfusion biopsies and control biopsies (taken fresh, before transport and perfusion) per section; each of the 9 ilei is listed. There were no significant differences in percentages of normal and degenerate neurons between perfused samples and control samples
