Intranasal insulin did not affect body weight and blood glucose levels. A: The body weight of all experimental animals decreased in the first few days after the surgery; however, all animals were able to regain body weight to the pre-surgery levels afterward. There were no significant differences among groups. Similarly, blood glucose levels dropped sharply in all animals at 24 h post-surgery, but returned to pre-surgery levels afterwards. There were no significant differences of blood glucose levels among treatment groups. *P<0.05 vs before surgery. N=16 in each group.
