Region-dependent effects of diabetes and insulin-replacement on neuronal nitric oxide synthase- and heme oxygenase-immunoreactive submucous neurons

Figure 6 Proportion of HO2-immunoreactive neurons related to the total number of submucous neurons in the duodenum, ileum and colon. A: Only in controls; B: In control, diabetic and insulin-treated diabetic rats. Data are expressed as mean ± SE; ^fP < 0.0001 vs control duodenum, ^gP < 0.0001 vs control ileum, ^bP < 0.001 vs controls, and ^cP < 0.05 vs diabetics; C: Controls; D: Diabetics. IR: Immunoreactive; ID: Insulin-treated diabetics.
