Figure 4 Representative immunofluorescence images of myenteric vasoactive intestinal peptide-immunoreactive positive neurons in full-thickness sections of canine gastric antrum (200 × magnification, scale bar = 50 μm). A: Representative images of anti-human neuronal protein HuC/HuD-immunoreactive (anti-Hu-IR) labeled neurons in diabetes mellitus (DM) + gastric electrical stimulation (GES); B: Representative images of vasoactive intestinal peptide-immunoreactive (VIP-IR) positive neurons in DM + GES; C: Representative merged images of anti-Hu-IR/VIP-IR in DM + GES; D: Representative images of anti-Hu-IR labeled neurons in DM + sham GES (SGES); E: Representative images of VIP-IR positive neurons in DM + SGES; F: Representative merged images of anti-Hu-IR/VIP-IR in DM + SGES; G: Representative images of anti-Hu-IR labeled neurons in control + GES; H: Representative images of VIP-IR positive neurons in control + GES; I: Representative merged images of anti-Hu-IR/VIP-IR in control + GES; J: Representative images of anti-Hu-IR labeled neurons in control + SGES; K: Representative images of VIP-IR positive neurons in control + SGES; L: Representative merged images of anti-Hu-IR/VIP-IR in control + SGES; M: Number of anti-Hu-IR positive neurons; N: Number of VIP-IR positive neurons; O: Proportion of VIP-IR positive neurons relative to total neurons. The proportion of VIP-IR neurons was significantly higher in the diabetes mellitus canines compared with controls, whether in GES or SGES subgroups (cP < 0.001). Anti-Hu: Anti-human neuronal protein HuC/HuD; DM: Diabetes mellitus; GES: Gastric electrical stimulation; IR: Immunoreactive; SGES: Sham gastric electrical stimulation; VIP: Vasoactive intestinal peptide.
