Total endoneurial and epineurial vascular luminal area in nerve stumps at 48 h and 2 weeks after sciatic nerve transection. Total endoneurial and epineurial vascular luminal area in nerve stumps at 48 h and 2 weeks after sciatic nerve transection. A: Proximal stump (5 mm from transection site). B: Distal stump (10 mm from transection site). Shams consisted of nerve exposure but no injury. Means ± SE are presented on a log10 scale for clarity. Five to six animals per group were used in the experiment. Diabetic and nondiabetic rats were compared at both time points using a one-way ANOVA with Bonferroni post hoc Student’s t tests. *P ≤ 0.05; **P ≤ 0.01 (n = 5–6). James M. Kennedy, and Douglas W.
