A: Total number of neurons in L5 dorsal root ganglia of long-term diabetic, recovered, and nondiabetic mice. A: Total number of neurons in L5 dorsal root ganglia of long-term diabetic, recovered, and nondiabetic mice. Recovered mice are those that originally were diabetic but that reverted to euglycemia between 6 and 9 months after diabetes initiation. Data are the means ± SE. All three groups were compared using a one-way ANOVA with Bonferroni post hoc comparison. *P < 0.05. B: Diameter histogram of L5 dorsal root ganglion neurons of long-term diabetic, recovered, and nondiabetic mice. Data are the means ± SE of each size. A two-way ANOVA was performed (treatment, P < 0.001; diameter, P < 0.001; interaction, not significant). James M. Kennedy, and Douglas W.
