Numbers of CGRP, galanin, GRP, NPY, PACAP, SP, VIP, and nNOS immunoreactive, NADPH diaphorase positive (A and C); and CGRP mRNA, galanin mRNA, NPY mRNA, VIP mRNA, and nNOS mRNA expressing (B and D) neuronal cell bodies in submucous (A and B) and myenteric (C and D) ganglia from sham operated and bypassed (1-10 weeks) rat ileum. The numbers of positive cell bodies are expressed as the percentage of the total number of cell bodies, established by EtBr staining. Mean (SEM). *p<0.05, **p<0.01, ***p<0.001 compared with sham operated; p values refer to one, two, or three bars, as indicated.
