Changes in blood glucose level, body weight, MWT, and TWL in STZ-induced diabetic rats. a. Diabetes induction was assessed by measurement of blood glucose level by using a blood glucose meter. b. Changes in body weight in control and diabetic rats. c. STZ-induced mechanical allodynia. d. STZ-induced thermal hyperalgesia. The data are presented as means ± SD. Naive, group naive; NS, group NS, which received only the NS; Group STZ, which received STZ; *P < 0.05 compared with the Naive and NS groups, n = 6 per group
