Pathological results at different concentrations of glucose and morphological score. a–i H/H, H/M, H/L, M/H, M/M, M/L, L/H, L/M, and L/L group, respectively (×400 magnification). j H/H and M/H groups had high scores. L/M and L/L groups had a low score. *p < 0.01 compared with the other groups. #p < 0.01 compared with the other groups. **p < 0.01 compared with H/H, H/M, H/L, M/H, M/M, M/L, and L/H groups. ##p < 0.01 compared with H/H, H/M, H/L, M/H, M/M, M/L, and L/H groups
