Distribution histograms that show CBS expression in dorsal root neurons of a normoglycemic and b diabetic rats 21 days after administration with streptozotocin. The graphs represent the number of CBS-positive neurons (black bars) or the number of NeuN-positive neurons (white bars) stratified according the neuron cross sectional area in μm2. Data are expressed as the average percentage ± SEM of 10–12 longitudinal cross-sections from three rats. There is no statistical difference between CBS-positive neurons of normoglycemic and diabetic rats (P > 0.05), as determined by two-way ANOVA
